The Proceedings, begun in 1878, is intended primarily as a medium for the publication of original papers, based on the collections of the National Museum, that set forth newly acquired facts in biology, anthropology, and geology, with descriptions of new forms and revisions of limited groups. Copies of each paper, in pamphlet form, are distributed as published to libraries and scientific organiza- tions and to specialists and others interested in the different subjects. The dates at which these separate papers are published are recorded in the table of contents of each of the volumes. The present volume is the seventy-second of this series. The Bulletin, the first of which was issued in 1875, consists of a series of separate publications comprising monographs of large zoological groups and other general systematic treatises (occasionally in several volumes), faunal works, reports of expeditions, catalogues of type-specimens, special collections, and other material of similar nature. The majority of the volumes are octavo in size, but a quarto size has been adopted in a few instances in which large plates were regarded as indispensable. In the Bulletin series appear volumes under the heading Contributions from the United States National Herbarium, in octavo form, published by the National Museum since 1902, which contain papers relating to the botanical collections of the Museum.

The special characteristics of this worm, as noted by that writer, are the two unequal pairs of teeth in the anterior and ventral portion of the mouth capsule, the inner or median pair being described as very small—in fact, almost rudimentary—and the presence of three small projections or teeth on each side of the dorsal edge of the mouth capsule. Alessandrini also noted in this species a ‘ small process with a rugged surface on each side of the cloacal aper- ture in the male. Ancylostoma plurideniatum was not reported again for 17 years, and then Vevers (1922) reported it from the intestine of Felis tigris, in the Malay States, noting certain minor differences between his specimens and Alessandrini’s description of this species. Two years later Chapin (1924) recorded it from a South American carnivore (Felis tigrina), which had died in the National Zoological Park in Washington, D. C. Chapin merely noted the presence of this species in the United States, but did not discuss the morphology of the worm. _In the opinion of Lane (1918) this species should be made the type of a new genus. : Lane has also considered the possibility that Alessandrini may have misinterpreted the structures on the dorsal edge of the mouth capsule as well as the two rugged structures near the cloacal aperture of the male, in which case the question of the possible identity of Ancylostoma pluridentatum with Ancyclostoma NO. 2697.—PROCEEDINGS U. S. NATIONAL Museum, VOL. 72. ArT. | 55216—27——1 ae Ti 2 PROCEEDINGS OF THE NATIONAL MUSEUM vou. 72 braziliense deserved serious consideration. Lane concluded, how- ever, that: “ The doubt can only be cleared up by the reexamination of Alessandrini’s original material, if this be still in existence.” Darling (1923) appears to accept the view that A. pluridentatum is probably identical with A. braziliense, basing this view on Ales- sandrini’s statement that the inner pair of teeth is almost rudi- mentary, a feature noted by Darling as well as by other investigators with reference to the corresponding teeth of A. braziliense. Darling states further that there is a possibility that the three dorsal teeth on each side of the mouth capsule as noted by Alessandrini may have been the result of some pathological condition. In view of the doubt expressed by Lane and Darling concerning the present status of Ancylostoma pluridentatum the writer exam- ined the specimens collected by Chapin from Felis tigrina as well as specimens of this species from two other lots present in the Helminthological collections of the United States National Museum. One lot was collected about a year ago from the intestine of a South American carnivore (felis eyra) that had died in the Na- tional Zoological Park, the specimens having been determined by Chapin and the writer. The second lot was discovered by the writer in the course of examinations of various specimens of hookworms from carnivores present in the helminthological col- lections of the United States National Museum. The lot in ques- tion was collected in January, 1905, from Fels species by Dr. Albert Hassall in the course of a post-mortem examination of the animal which had died in the National Zoological Park. These specimens were later examined by Dr. C. W. Stiles, of the hygienic laboratory of the United States Public Health Service, who labeled them “Ancylostoma, new species.” It should be noted in this con- nection that Doctor Stiles’s determination was made before Ales- sandrini’s description of A. pluridentatum was published. The observations recorded in this paper not only confirm the specific validity of A. pluridentatwm, based on a study of specimens from the type locality, but also clear up certain points in the morphology of these worms that led Darling to the view that Ancylostoma pluridentatum and Ancylostoma braziliense are prob- ably identical. DESCRIPTION OF ANCYLOSTOMA PLURIDENTATUM The features of the mouth capsule that differentiate Ancylostoma pluridentatum from all other species of the genus Ancylostoma are the structure of the two pairs of teeth in the anterior and ventral portion of the mouth capsule, coupled with the presence of three small teeth on each side of the dorsal wall of the mouth. (Fig. 1.) As has already been said these features were noted and emphasized by ART. 1 ANCYLOSTOMA PLURIDENTATUM—SCHWARTZ 3 Alessandrini who described the inner ventral teeth as being very small in comparison with the large outer teeth. So far as concerns the relative size of the pair of inner teeth, the writer has not been able to confirm Alessandrini’s findings, as the inner pair of teeth in the specimens examined was found to be of good size. How- ever, Alessandrini’s interpretation of the size of the inner teeth may have been due to his study of imperfectly cleared specimens or to an interpretation of the tips of the teeth as teeth with the remaining broad portion regarded as a basal plate to which they were attached, instead of regarding the entire structure as a tooth in each case as the writer has regarded them. In specimens imperfectly cleared only the tips of the inner teeth which point caudad are visible, since they protrude beyond the margin of the outer teeth, the remaining portion of these teeth, which lie in a more or less horizontal plane, being covered by the outer teeth. When the buccal capsule is viewed through the ventral surface, however, the inner teeth which are more ventrally placed than the outer teeth, stand out quite distinctly in well cleared specimens, and are seen to be discrete structures, and of good size. The tips of the outer teeth are relatively large and con- spicuous, and have the shape of a triangle. In certain specimens from Felis tigrina the tips of the outer teeth were found to be truncated in a number of specimens (fig. 4), resem- bling in this respect the corresponding teeth of Ancylostoma brazili- ensé, in which similar malformations of the outer teeth are by no means uncommon. In A. pluridentatum the abnormality in the outer teeth is sometimes unilateral and sometimes bilateral. In some speci- mens the tip of the tooth appears to be cut off cleanly whereas in other specimens it presents the appearance of an uneven surface sug- gestive of erosion. Abnormalities were also observed in the three pairs of smail dorsal teeth in specimens from els tigrina. The mid- dle tooth on one or both sides is the one affected, and appears to be eroded in certain specimens. In some specimens the tips of the teeth are almost entirely absent, the characteristically pointed tooth being replaced by a slightly concave or by a more or less irregularly fiat- tened cuticular elevation. Normally the dorsal teeth end in sharp points. No abnormalities of the teeth were observed in specimens from Felis eyra and from Felis species. The cephalic papillae are very conspicuous and are located anterior to the nerve ring. Their position with respect to the middle of the esophagus is by no means constant, being either slightly anterior or posterior to the middle of the esophagus. The position of the excre- tory pore is slightly posterior to the nerve ring. Male.—The males are from 7 to 8 mm. long by about 294 wide in the middle of the body. The maximum width of the body is imme- diately in front of the bursa which has a diameter of from 302 to 4 PROCEEDINGS OF THE NATIONAL MUSEUM vou. 72 310. The buccal capsule is from 131 to 1784 wide. The esophagus (fig. 8) is from 638 to 7404 long by 1682 in maximum width. ‘The nerve ring is located anterior to the middle of the esophagus, dividing the latter into two parts having an approximate ratio of 4 to 6. In a specimen from Felis tigrina the cervical papillae divide the esoph- agus into two parts, the ratio of the anterior part to the posterior part being 17 to 13, whereas in a Species from Felis eyra this ratio is 25 to 17. The spicules are long and slender Ge 6), and are from 1.15 to 1.17 mm. long. The short gubernaculum is from 60 to 74» long by 10u wide. The bursa (fig. 5) is from 470 to 554 wide when spread out. The ventro-ventral ray isa little longer and also somewhat wider than the latero-ventral ray. The tips of these rays extend to within a short distance from the margin of the bursa. The externo-lateral ray, which terminates at a considerable distance from the edge of the bursa, is much smaller than the medio-lateral and postero-lateral rays from which it diverges. The medio-lateral and postero-lateral rays are large and parallel, their tips extending almost to the poste- rior margin of the lateral lobes of the bursa. The distance between the tips of the externo-lateral rays when the bursa is viewed from the dorsal aspect is 180n. The dorsal ray is from 151 to 168 long and divides into two branches at a distance of about 35, from the posterior end. Each branch of the dorsal ray is tridigitate. The prebursal papillae are located at a distance of 504 from the posterior margin of the lateral lobes of the bursa. As noted by Alessandrini, a rugged structure is present on each side near the anogenital opening. (fig. 6), the surface of which appears granular in optical section. Female—The females are from 10 to 11 mm. long by 344 to 378u wide in the region of the vulva. The maximum diameter of the buccal capsule varies from 168 to 210u. The esophagus is from 739 to 806u long by 185 to 2104 in maximum width. The cephalic papillae divide the esophagus into two unequal parts, the ratio of the portion anterior to the papillae to that posterior to the papillae being 26:20 in a specimen from Felis tigrina, whereas in a specimen from Felis eyra the ratio is 22:23. The nerve ring is anterior to the cephalic papillae, the excretory pore being in a position inter- mediate between the nerve ring and cephalic papillae. The vulva is located near the beginning of the posterior third of the body. In an immature specimen about 8 mm. long the vulva is located at a distance of 2.8 mm. from the tip of the tail. In a speci- men about 11 mm. long the distance from the vulva to the tip of the tail is 3.3 mm. The tail (fig. 2) is from 126 to 176u long and is gradually attenuated. The slender bristle that is inserted in the tip of the tail is from 17 to 25n long.

RAY 55216—27——2 6 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 72 DISCUSSION It will be noted from the description that there are certain slight differences in the morphology of the worms from Felis tigrina and Felis eyra, the most important differences being in the position of the cephalic papillae and in what appear to be malformations of the teeth. In specimens from felis tigrina the cephalic papillae are located anterior to the middle of the esophagus and but slightly posterior to the nerve ring, whereas in specimens from Felis eyra the cephalic papillae are located posterior to the middle of the esophagus and considerably posterior to the nerve ring. Other minor differences in specimens from the two hosts were noted but these were rather variable, and possibly due to the fact that the worms from /’, tigrina are not fully grown. So far as concerns Lane’s suggestion that Ancylostoma pluriden- tatwm represents a new genus, the writer is of the opinion that Lane’s judgment was sound in not actually proposing a new generic name, that the special differentiating characters of this worm should be regarded at this time as of specific rank, and that for the present, at least, these parasites may be left in the genus Ancylostoma since they possess all of the essential characters of this genus. If for no other reason than that of convenience, the creation of a new genus for A. pluridentatwm is avoided in this paper as not justified at the present time owing to the comparatively small number of easily differentiated species now assigned to the genus Ancylos- toma. In general we feel that dividing a comparatively small and coherent genus to form from one of its species a new genus containing only that species frequently adds unwarrantably to the already bur- densome nomenclature with which the taxonomist must cope. Should other forms be found to share with A. pluridentatum characters not shared by other species assignable to Ancylostoma, it will then be time to consider the proposal of a genus for this group. SPECIES OF THE GENUS ANCYLOSTOMA Yorke and Maplestone (1926) list the following species as belong- ing to the genus Ancylostoma: A. ducdenale (Dubini, 1843) Crep- lin, 1845, type species of the genus; A. braziliense de Faria, 1910; A. caninum (Ercolani, 1859); A. conepati (Solanet, 1911); A. gél- soni Gedoelst, 1917; A. malayanum. (Alessandrini, 1905); A. méné- mum (Linstow, 1906); A. mucronatum (Molin, 1861); A. myceées, new name, Yorke and Maplestone, 1926 (= Diploodon quadridentatum Molin, 1861); A. pluridentatum (Alessandrini, 1905). Mbolin’s two species are inadequately described, but his figures indicate quite clearly that they belong to the genus Ancylostoma. His figure of A. mucronatum shows two equal spicules nearly one-fourth as long as the total length of the male. In this connection it is interesting ART. 1 © ANCYLOSTOMA PLURIDEN TATUM—SCHWARTZ 7 to note that the males of A. conepati, which have an average length of 8.8 mm., have long spicules, their average size being 2 mm., the ratio of the length of the spicules to the total length of the body being practically the same in this species as in A. mucronatum. ‘The fact that both of these species occur in South America is of further interest in connection with their possible identity. It may be noted, however, that A. mucronatum is from an edentate, Dasypus gilvipes, whereas A. conepati is from a carnivore, Conepatus suffocans. However, owing to the paucity of morphological data regarding A. mucronatum the question of the possible identity of this form with A. conepati is left open. Both of these species appear to be closely related to A. caninum, differing from the latter primarily in the lengths of the spicules. Molin’s figure of Diploodon quadriden- tatum (=A miycetis) shows two pairs of well-developed teeth in the anterior portion of the mouth capsule. Male specimens of this species were not available to Molin, his description and figure being based on a female. Whether this form, collected from a primate (Mycetes coraya), is A. duodenale or whether it represents a dis- tinct species can not be decided on the basis of Molin’s description. A. minimum is inadequately described, there being no reference to teeth in the anterior portion of the buccal capsule. Von Linstow’s ficure of the bursa suggests that the species may belong to the genus Ancylostoma, nceaeoll the possibility that he was Fiolhae with a species of Uncinaria must also be taken into poidideralion So far as can be judged from the arrangement of the bursal rays, this species is related to forms such as A. braziliense and other species of this genus, which have but two pairs of teeth in the anterior por- tion of the buccal capsule. A. gilsont Gedoelst, 1917, from Sczurus prevosti, is regarded by the writer as a synonym of A. bra- ziliense, since the figures and measurements of this species given by Gedoelst agree in practically all respects with available figures and descriptions of A. braziliense and with the writer’s ob- servations on that species based on a study of specimens from the United States, South America, and various parts of Asia. Gedoelst has apparently created A. gilsoni largely on the basis of host rela- tionship and does not point out in what respects this species differs from A. braziliense. Our present knowledge of host relationships of species of the genus Ancylostoma does not appear to justify the erection of a new species on this basis alone, since certain species of this genus are known to occur in aberrant hosts. This is especially true with reference to A. braziliense, which occurs not only in species of carnivores but also occasionally in man, in which host it attains fertile maturity. Lane (1916) has called attention to the fact that in species of ae genus Ancylostoma which contain three pairs of teeth in the anterior 8 PROCEEDINGS OF THE NATIONAL MUSEUM VoL. 72 ventral portion of the mouth capsule, the medio-lateral and postero- lateral rays are divergent, the cleft between these rays being deeper than that between the externo-lateral and medio-lateral rays, whereas in forms having two pairs of teeth in the anterior ventral portion of the buccal capsule the medio-lateral and postero-lateral rays he close together and parallel, the cleft formed between these rays not being deeper than that formed between the externo-lateral and medio- lateral rays. The following key will serve to differentiate the species of Ancy- lostoma* and to indicate their relationships. I.

In connection with the above key it is worth noting that the teeth in the anterior ventral portion of the buccal capsule of species of Ancylostoma show a series of stages which may be interpreted as being either progressive or regressive in nature. In A. caninum, A. conepati, and A. mucronatum three pairs of well-developed teeth are present in the anterior ventral portion of the buccal capsule; in A. duodenale the inner of the three pairs of teeth is very small, in fact, almost rudimentary; in A. malayanum and, so far as can be judged from Molin’s figure, in A. mycetis, only two pairs of well- developed teeth are present in the anterior ventral portion of the buccal capsule; in A. pluridentatum and in A. braziliense two pairs of teeth are present, the inner pair of teeth being reduced in size, the 14, minimum is not included in this key owing to the absence of knowledge regarding the presence of teeth in the anterior ventral portion of the buccal capsule. Assuming that von Linstow’s species belongs to the genus Ancylostoma, it has affinities with the forms in Group II so far as can be judged from his figure of the bursa. ART. 1 ANCYLOSTOMA PLURIDENTATUM—SCHWARTZ 9 buccal capsule containing in the anterior ventral portion one pair of well-developed teeth and one pair of small or rudimentary teeth. In certain specimens of A. braziliense collected by the writer from a cat which was shipped from Florida the inner pair of small teeth was found to be entirely absent, whereas in other specimens from the same host it was present. This observation suggests the possibility of the occurrence of a variety of Ancylostoma braziliense containing but a single pair of teeth. Such variation, if germinal in character and not due merely to external causes, undoubtedly represents an incipient species. It is suggested, purely as an interesting speculation, that the various species of Ancylostoma containing less than three pairs of well-developed teeth in the anterior oral margin may have arisen from forms containing three pairs of teeth, each species representing a mutation.

MarsHatt, Assistant Curator, Division of Mollusks, United States National Museum In my paper “ New Uruguayan Mollusks of the Genus Corbicula ”* I described : Corbicula (Cyanocyclas) circularis. Corbicula (Cyanocyclas) compacta. Corbicula (Cyanocyclas) delicata. Corbicula (Cyanocyclas) exquista. Corbicula (Cyanocyclas) felipponei. Corbicula (Cyanocyclas) fortis. Corbicula (Cyanocyclas) oleana. Corbicula (Cyanocyclas) paysanduensis. Specimens from Brazil, which were already in the Museum collec- tion, and many specimens, all of them from the Department of Colonia, Uruguay, and nearly all from the Bay of Colonia in the Rio de la Plata, lately received from Prof. Auguste Teisseire, Directeur du Lycee Departemental de Colonia, make it necessary to describe six new species. im many specimens of Corbicula there are radiating splashes of purple along the interior edge of the ventral margin. When these: occur there should be a corresponding ray, usually of reddish, on: the outer surface and often such rays will be revealed by careful. examination although at first their presence may be unsuspected. In same specimens in which there are rays it is impossible to detect them, because of a thickening of the periostracum which makes it nontranslucent.. In such cases if the periostracum be removed the rays will show clearly on the white background; or if a longitudinal section of the shell be made dots of color will show where the rays were cut. When radiating splashes of purple occur along the ventral inner edge they are a sure sign that rays, even though invisible, are present on the outside, and it is unnecessary to remove the 11924, Proc. U. S. Nat. Mus., vol. 66, art. 15, pp. 1-12. No. 2699.—PRocEEDINGS U. S.

On the outside the rays are single, narrow “clear-cut” and reddish, but on the inner margin many of them are double, broad, blurred, purple, or deep lavender. A section across the rays near the ventral margin shows that there they go entirely through the calcareous portion of the shell. In sections made nearer the beaks they go at least part way through. Several of the specimens received from Professor Teisseire con- tained young. When collected, these specimens were not cleaned, and the young of various ages are included in the dried flesh of the females. The young are in perfect condition. A fine specimen of C’. felipponei (Cat. No. 365390) from the Bey of Colonia contained embryonic and nepionic shells. The latter were probably not yet developed to the age of extrusion, as they are smaller than one would expect from the size of the adult. In these young, which are very pale straw color, there is a splash of purple on the anterior area and one on the posterior. Immediately after the close of the embryonic stage fine radiating lines of lavender make their appearance. Such lines occur in specimens not more than a millimeter in length. CORBICULA (CYANOCYCLAS) TEISSEIREI, new species Plate 1, figs. 1, 2 Shell rather thin, nearly elliptic, rounded and slightly narrower in front, more broadly rounded at the rear; a little inflated, beaks rather low, situated at the middle of the dorsal line, which is well arched. Ventral line regularly curved. Posterior and anterior ridges not well defined, the descent to the margin more abrupt at the rear than in front. Periostracum generally clothlike and dull, but slightly glossy on the convexity of the shell. Sculpture of numerous concentric striae, which develop into fine ribs on the an- terior area. Color brownish with an olivaceous cast and with three obscure broad fuscous rays in the vicinity of the posterior ridge, and with faint radiating lines of color over the general surface. The shell being “dead” the color of the interior has changed to nearly uniform purple. (Fresh specimens have the interior gay with pink, lavender, and purple, with three broad purple interrupted rays indicating the location of the three fuscous rays of the ex- terior—a number of fine lavender rays unequally distributed.) In the right valve the middle and posterior cardinal teeth are distinctly grooved on the summit, the anterior cardinal small and thin, In the left valve none of the cardinals is grooved, and the posterior one is small and thin. In both valves the cardinals are widely divergent. In the right valve the two posterior laterals are rather ART. 3 MOLLUSKS FROM URUGUAY AND BRAZIL-—MARSHALL 5 distant from the beak, the inner lateral being finely crenulated on its upper surface. In this valve the two anterior laterals begin near the beak, the inner one being finely crenulated on its upper surface. Left valve with one anterior and one posterior lateral, both crenulated on the edge. Anterior adductor scar deep; pos- terior scar not so deep, but well marked. The type (Cat. No. 365382, U.S.N.M.) measures: Length, 27.5 mm.; height, 23 mm.; diameter, 14 mm. It comes from Arroyos in the Department of Colonia, Uruguay, and was collected and pre- sented by Prof. Auguste Teisseire. The finest specimen of all (Cat. No. 365380, U.S.N.M.) measuring: Length, 28 mm.; height, 23 mm.; diameter, 15 mm.; has the teeth abnormal and therefore could not be used as type. The abnormality consists in having the two posterior cardinals of each valve fused into a single tooth. The interior of this specimen is especially gay with mixed colors of white, pink, lavender, and purple. Other specimens which retain the true coloring of the interior show these gay colors to be usual with the species. Younger and weathered shells are greenish, or pinkish on the outside and show several radi- ating fine lines. CORBICULA (CYANOCYCLAS) SIMPLEX, new species Plate 1, figs. 3, 4 Shell rather thin, somewhat inflated, nearly round, but broader at the rear than front, posteriorly subtruncate, anteriorly slightly ex- tended. Dorsal margin well arched, beaks a little behind the middle, anterior dorsal margin very oblique, posterior dorsal margin gently sloping and shorter. Ventral margin regularly curved, rounding gradually into the anterior margin and suddenly into the posterior margin. Posterior ridge high but rounded; anterior ridge indis- tinct; sculpture of fine concentric striae, more marked in front than in the rear. Rest perieds distinctly marked by deeper lines and blackish color. Color olive green with a broad darker green ray on the posterior ridge and two similar rays on the posterior dorsal area. Interior purple with a white edging around the margin, the exterior rays indicated by purple rays in the interior. In right valve the anterior cardinal is minute and oblique, the middle cardinal thick and deeply bifid, the posterior cardinal thick and moderately bifid and oblique. In the left valve the anterior cardinal is moderately thick, the middle cardinal is thick and deeply bifid, the posterior cardinal long and thin. Right valve with two anterior and two posterior laterals which are rather low and short, the inner ones crenulated. Left valve with a single lateral in front and one at the rear, both rather high and both crenulated. Adductor scars deeply impressed, pallial sinus well marked. = PROCEEDINGS OF THE NATIONAL MUSEUM VoL. 72 The type (Cat. No. 365385, U.S.N.M.) measures: Length, 24.5 mm.; height, 21.5 mm.; diameter, 18.5 mm. It and a single valve (Cat. No. 365386, U.S.N.M.) come from Arroyosin the Department of Colonia, Uruguay, and were collected and presented by Prof. Auguste Teisseire. This species is closely related to (. tedsseirei, but differs in the shortened posterior end and in the greenish color. Two specimens (Cat. Nos. 365387 and 365388) from Arroyos in the Department of Colonia, Uruguay, sent by Professor Teisseire, contain young in the dried flesh of the mother. The largest of these young is 444 mm. long. The parent shell has a length of 2114 mm. In the young the tips of the beaks are glassy, tinged with lavender, followed by a broad splash of white, which is surrounded by an irregular circle of violet, then a whitish, concentric band and the ventral portion purplish. The posterior area shows three purple rays. These are the beginnings of the three external fuscous rays and internal purple rays of the adult. CORBICULA (CYANOCYCLAS) GUAHYBENSIS, new species \ Plate 1, figs. 9, 10 Shell small, rather compressed, nearly elliptic, slightly narrower in front than behind. Dorsal margin regularly curved, beaks a little in front of the middle, anterior dorsal margin slightly more oblique than the posterior. Ventral margin lightly curved, rounding grad- ually into the anterior margin and somewhat more sharply into the posterior. Anterior and posterior ridges rounded, not well defined. Sculpture of numerous fine concentric striae, stronger on the an- terior and posterior areas; the rest periods emphasized. Most of the shell glossy, very light straw color, becoming darker with dis- tance from the beaks. Surface with a number of narrow, unequal reddish rays, three of which are more prominent than the others. Interior mostly white with a large spot of lavender in the upper part. In right valve the anterior and posterior cardinals are oblique and thin, the latter larger than the former, the middle tooth thick and slightly bifid on its summit. In left valve the anterior cardinal is thicker and shorter than the posterior; the middle tooth thick and distinctly bifid. In right valve the two pairs of laterals are short and stout, the groove between each pair wide and deep, and the inner ones finely and sharply crenulated. In left valve there is one ante- rior and one posterior lateral, both of which are rather thick and finely crenulated. Adductor scars deep; the sinus in the pallial line wide, obtusely pointed, and unusually well marked. The type (Cat. No. 171426, U.S.N.M.) measures: Length, 15 mm.; height, 13 mm.; cliameter, 844 mm. It and 28 paratypes (Cat. No. ~ art. 3 MOLLUSKS FROM URUGUAY AND BRAZIL—MARSHALL 19) - 122321, U.S.N.M.) come from the Guahyba River, Rio Grande do Sul, Brazil, and were presented by Dr. H. von Ihering. Almost any one of the specimens might have been selected for the type as the variation among them as to form, color, and sculpture is very slight, while in size most of them approximate the type. This species is related to C’. dimosa but is distinguished at once by the smaller size, the slightly more elongate form, and especially by the very pale color. CORBICULA (CYANOCYCLAS) UNDULATA, new species 9 Plate 1, figs. 5, 6 Shell rather thick, subtriangular, inflated, obliquely truncated posteriorly, rounded and slightly extended anteriorly, dorsal line much arched, ventral margin evenly rounded, curving regularly into the anterior margin, and more sharply into the posterior margin. Posterior aspect wedge shaped, wide, and nearly at right angles with the convexity of the shell. Beaks high and moderately nar- row, pointing forward. Posterior ridge high and abrupt; anterior ridge low and not well defined. Sculpture consisting of numerous concentric ribs on the upper part of the shell which become less marked near the ventral margin; on the posterior area there are indications of obscure radiating ridges. Color dark yellowish olive, with a number of green radiating lines which are not uniform in width nor evenly spaced. Interior mainly dark purple, with lighter area in the middle and along the margins. Each of the radiating hnes on the outer surface is marked by a dark purple spot on the inner margin; pallial line and adductor scars well marked, and the pallial sinus deep and wide. In each valve there are three cardinal teeth, widely divergent. In right valve the an- terior cardinal is thin and platelike, the middle cardinal thick and slightly bifid, the posterior cardinal medium thick and long and bifid throughout its length. In left valve the anterior cardinal is thick, the middle one like the one in the right valve, and the posterior one thin. The right valve has two laterals anteriorly and two pos- teriorly, rather short and stout and crenulated. The left valve with a Short, thick, crenulated lateral anteriorly and posteriorly. The type (Cat. No. 365392, U.S.N.M.,) measures: Length, 19 mm.; height, 17 mm.; diameter, 13 mm. It comes from the Bay of Colonia, Rio de la Plata, Uruguay, and was collected and presented by Prof. Auguste Teisseire. This species differs from coloniemsis chiefly in the strong ‘concentric ribs. Its proportions, too, are different, as it is more ral 6 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 72 CORBICULA (CYANOCYCLAS) ITHERINGI, new species Plate 1, figs. 11, 12 Like C. coloniensis in color and to a great extent in form, but the posterior ridge not so marked, the posterior area less wedge shaped, the cardinal teeth relatively smaller and the lateral teeth relatively longer and thinner. The type (Cat. No. 171423, U.S.N.M.) consists of a single valve. It measures: Length, 22 mm.; height, 18.5 mm.; diameter (if both valves were present) would be 12mm. It comes from S. Leopols, Rio Grande do Sul, Brail, and was presented by Dr. H. von Ihering. This may prove to be a subspecies of C’. coloniensis, its variation from type due to a distant habitat. CORBICULA (CYANOCYCLAS) PLATENSIS, new species Plate 1, figs. 7, 8 Shell subequitrangular, thick, inflated, obliquely truncate pos- teriorly extended and sharply rounded anteriorly, dorsal line much arched, ventral margin evenly rounded, curving regularly into the anterior margin and angularly into the posterior margin. Both the anterior and posterior aspects wedge shaped, wide, and rounding into the convexity of the shell. Beaks high, located at the middle of the dorsal line, pointing forward. Posterior ridge high but rounded, the descent to the posterior margin rapid. Anterior ridge gradually rounded. Posterior end of shell slightly nasute. Beaks eroded, white at the tips and then deep purple. General color dark chestnut on a clothlike periostracum, the dorsal area slightly lighter. Several scarcely visible dark radiating lines. Interior mostly purplish, the cardinal teeth white, the lateral teeth and an area at the front and one at the rear delicate pink. Concavity pale purple, area between ventral border and pallial line deep rich purple rayed with white; a wide purple ray marking the posterior angle. In the right valve the anterior cardinal tooth is thin, platelike and very oblique; the middle tooth is thick and deeply bifid; the posterior tooth moderately thick, indistinctly bifid and oblique. In the left valve the anterior tooth is thicker than in the right valve, the middle tooth thick and slightly bifid, the posterior tooth thin. In right valve there are two anterior and two posterior lateral teeth, the inner ones crenulated. The left valve with one anterior and one posterior lateral tooth, the former the smaller, the latter very high, and both of them very sharply crenulated. Adductor scars not very prominent, sinus well marked, deep, and sharply pointed. The type (Cat. No. 365393, U.S.N.M.) measures: Length, 26.5 mm.; height, 23.5 mm.; diameter, 17.5 mm. It comes from the Bay ART. 3 MOLLUSKS FROM URUGUAY AND BRAZIL—MARSHALL 7 of Colonia, Rio de la Plata, Uruguay, and was collected and presented by Prof. Auguste Teisseire. This species belongs in the same group with C. felipponei and coloniensis. The clothlike periostracum and the more nasute form and greater inflation serve to differentiate it from them. It is a connecting link between C. coloniensis and C. fortis, distinct from both and yet partaking of the characteristics of each.

Merrit. Head Ourator of Geology, United States National Museum The recently received F. A. Canfield bequest of minerals contained representatives of seven falls of meteorites one of which (that of Nanjemoy, Md.) was a stone, one a pallasite, and the remaining five irons. Among these last were two with localities quite too indefinite to make them of great value or consequence, but which should nevertheless be recorded. These are as foilows: [1] Bolivia (Cat. No. 793) —This is a complete individual in form of a flattened oval (see pl. 1) without deep pittings or unusual surface markings, quite fresh, and weighing 21.25 kilograms (46.75 lbs.). The only information regarding it is given in Canfield’s own hand in a leaf from an old letter of which the first page and date are miss- ing. It reads: “A friend has given me a mass of meteoric iron which weighs 47 pounds and has never been cut. It was found 30 years ago and purchased by a priest, who thinking it was silver paid $600 in gold for it.” The iron is soft and malleable, and etches but poorly (pl. 2, lower), showing irregular somewhat wavy kamacite bands with little or no plessite and taenite in minute, almost microscopic films; schreibersite 1s present in scattered granules. The kamacite bands show under a low power a very fine granular structure. A representative piece submitted to EK. V. Shannon was reported on as follows: The piece of the iron which, ground free from scale, was used for the analysis weighed 22.1825 grams. Except insoluble matter, copper, and platinum, the determinations were made upon aliquot portions of this solution equivalent to 1.1066 grams each. Copper and platinum were determined in the residuum of the solution equivalent to 15.4929 grams of the iron. ‘The results of the analysis are as follows: No. 2700.—PROCEEDINGS U. S.

It is probably all extraneous. The reaction for platinum is of special interest. A portion of the hydrochloric acid solution of the iron equivalent to 15.4929 grams was saturated with hydrogen disulphide (H,S) and filtered. The separated sulphur was filtered out together with the platinum (Pt) and copper (Cu) as sulphides, and ignited in a porcelain crucible. | The residue, consisting in considerable part of iron oxide, was digested overnight in strong hot hydrochloric acid, diluted and fil- tered through a very small filter. The filter paper showed a visible black residue (PtS?). This was returned to the porcelain crucible, ignited and treated with aqua regia in the crucible and evaporated to dryness. After several evaporations to dryness with hydrochloric acid to expel free chlorine and nitrates the residue was several times evaporated to dryness with water, taken up in water and a few drops of potassium iodide were added. The red color characteristic of platinum immediately appeared. The procedure was repeated and the result was the same. This composition taken in connection with the structure would relegate the mass to the class of kamacite octahedrites. [2] Western Arkansas (Cat. No. 794).—This is a somewhat rounded triangular mass, polished and etched on one side and weigh- ing 1.75 kilograms. It was labeled in Canfield’s hand “Meteor found in Arkansas, presented by I. Price Wetherill, (?) June, 1890,” and on the obverse “ Mr. Wilkins said a native mountaineer brought this specimen to him in Joplin.” With so little of its history known the iron would have not been considered worthy of investigation but for peculiarities noted below. ’ The iron etches very poorly, yielding a dull lusterless surface on which the taenite plates are so thin as to be scarcely distinguish- able but by the aid of a lens. The kamacite bands are rarely over 1 millimeter in thickness and are very finely granulated throughout. Two very thin dull black wavy lines or veins the nature of which can not be determined traverse this face diagonally. Numerous very “ABT. 4: SOME NEW METEORIC IRONS——-MERRILL 3 small glistening points are assumed to be schreibersite. On account of lack of information regarding it further investigation was not attempted. Mr. Shannon has, however, made an analysis, the results of which are given in column I below. The iron was analyzed by the usual methods on a piece, ground free from scale or inclusions, weighing 11.0383 grams.

McCallie (of the Georgia State Survey) has but recently reported an iron found at a locality called Social Circle in his State that presents an almost identical appearance and granu- lated etched surface. The composition (column II above) agrees so closely that both analyses might have been thought made from the same mass except for the 0.09 per cent of tin, which is perhaps open to question. [3] Seneca Township, Lenawee County, Michigan (Cat. No.786) — This iron was brought to my attention by Stuart H. Perry, of the Adrian Daily Telegram, with the statement that it was found in July, 1923, and that it is supposed to be the result of a fall seen at Seneca ‘Township in 1914. The evidence thus far submitted can not, however, be considered as altogether confirmatory. As shown in the plate (pl. 2, upper), the mass is in the form of a flattened oval, and though oxidized and scaling somewhat on the outer surface still shows traces of the larger original thumb mark- ings. That it has lain exposed for some years is unmistakable. The present weight is 11.5 kilograms. An analysis by E. V.

MISSISSIPPIAN SPECIES By Grace B. Hotmes Of the Hastern High School, Washington, D. C. INTRODUCTION The present contributions to the study of the conodonts was pre- pared at the suggestion of Dr. R. S. Bassler and under his direction in the paleontological laboratory of the United States National Museum where extensive collections of these toothlike structures were avail- able. As Doctors Ulrich and Bassler had just completed their paper on the classification of the conodonts and had apphed their new classification in the description of an Upper Devonian fauna of western New York and an early Mississippian one from Tennessee, it was thought best that my work should carry these studies to the Mississippian rocks of Alabama and also include for the ready refer- ence by students illustrations of previously described species, with exception of three publications, and a bibliography of the group. The exceptions mentioned refer to the work of Bryant in 1921, Ulrich and Bassler in 1926, and Roundy in 1926, copies of which are still available to the student. ZOOLOGICAL AFFINITIES OF THE CONODONTS The affinities of the conodonts have been a subject of controversy almost since their discovery by Pander in 1856. That there was no doubt in Pander’s mind as to their relationship may be ascertained from the title of his monograph. He studied the internal as well as the external structure of the fossils and saw in their formation fishlike characters somewhat of the Selachian type. The question concerning the affinities of these fossils seems to have had its birth in the mind of Dr. J. S. Newberry, of Ohio, who after studying specimens found in the Cleveland shales remained undecided for some years whether they were Marsipobranchii (Cyclostomata) or Annelids. Hinde, who made the most comprehensive study of conodonts of any paleontologist up to Bryant’s work of 1921, classified them as primitive vertebrates, probably Myxinoids. He based his conclu- sions upon two facts: First, no gastropods which possessed such No. 2701.—PROCEEDINGS U. S. NATIONAL MUSEUM, VOL. 72, ART. 5. 55414—28——__1 1 2 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 72 teeth were found in the same formations nor did any crustaceans have such spines; and, secondly, the annelid jaws which he found | in the same beds are composed of chitin, while the conodont teeth contain both calcium carbonate and calcium phosphate. He was of the same opinion in 1900, namely, that the teeth belonged to fish rather than to some invertebrate. In 1886 Rohon and Zittel decided that “the conodonts have structurally nothing in common either with the dentine of Selachia and other fishes, the horny teeth of Cyclostomi, the lingual teeth of the Mollusca, the hooklets of the Cephalopoda, or the broken segment spines of the Crustacea; on the other hand, both in form and in structure, they agree remarkably with the masticatory apparatus of the Annelida and Gephyrea.” ‘They came to the conclusion that since there is this agreement, all these microscopic teeth, those ac- knowledged by Hinde to be annelids and those which he called conodonts, are the oral or oesophageal teeth of worms. In reviewing the literature on conodonts it will be found that the most thorough students of these fossils believe they are the remains. of primitive vertebrates, probably some simple fish. In neither of John Smith’s papers on conodonts of Scotland can one find a sug- gestion that these are not fish teeth, but an exception is found when Asser Hadding places them in the phylum Annelida. In Grabau’s Text-Book of Geology, conodonts are described as horny, jawlike, or toothed structures developed within the body—the oesophageal jaws of worms. Bryant in 1921 remarks: “ On the whole, the longer I have studied these organisms the more have I become convinced that the true conodonts have hardly anything really diagnostic in common with annelid jaws. If, as I shall hereinafter try to demonstrate, certain of the leaflike forms are of the nature of pavement teeth, then the conclusion seems almost unavoidable that the conodonts must be con- sidered as the dentition of some primitive type of fishes.” In the recent publication on the subject of conodonts by Ulrich and Bassler they are regarded as teeth and plates of primitive fish. Their classification is as follows: Class PISCES TYPICAL CONODONTS (teeth of primitive fishes) Family DISTACODIDAE Ulrich and Bassler Distacodus Hinde, 1879 (Machairodus Pander, 1856, preoccupied; Machairodia Smith, 1907); Acodus Pander, 1856; Acontiodus Pan- der, 1856; Drepanodus Pander, 1856; Scolopodus Pander, 1856; Oistodus Pander, 1856; Paltodus Pander, 1856. ‘arr, 5 BIBLIOGRAPHY OF THE CONODONTS—HOLMES BS _ Family PRIONIODIDAE Ulrich and Bassler Prioniodus Pander, 1856; Sudprioniodus Smith, 1907; Cordylodus Pander, 1856; Belodus Pander, 1856; Ligonodina, Ulrich and Bassler.

Family PRIONIODINIDAE Ulrich and Bassler, 1926 Genus HINDEODELLA Ulrich and Bassler, 1926 HINPEGDELLA TENERRIMA, new species Plate 9, figs. 6, 7 A long, thin, sharp pointed cusp rises from a very slender bar. Two broken denticles are on one side of the cusp and nine or ten are on the other side, all widely spaced. Due to the concavity of the bar immediately below the cusp, it may be inferred that this is the inner side of the jaw. Cotypes.—Cat. No. 11435, U.S.N.M. HINDEOGDELLA MINUTIDENS, new species late 9, fig. § The upright denticles in this specimen are so minute and regularly, though closely, spaced and the bar is so long and flat that this conodont resembles a fine-toothed saw. Holotype.—Cat. No. 11486, U.S.N.M. HINDEODELLA GERMANA, new species Plate 9, fig. 9 The anterior side of the bar is very thick and bears several needle- like, irregular denticles. On the posterior side the denticles, which slant backward, are alternately long and short. In one or two places two small denticles are found between the longer ones. The pos- terior end of the bar terminates in a spinelike point. Holotype.—Cat. No. 11437, U.S.N.M. HINDEODELLA SUBTILIS Ulrich and Eassier Plate 9, figs. 10, 11 1926.

Main cusp located at the point of downward bending, followed posteriorly by two equally large denticles separated by a minute one. Rest of bar occupied by narrow, more delicate denticles decreasing in size to the extremities. The irregularity of curvature and the three larger central denticles characterize this species.

Denticles all similar, being delicate and needle- like, but the long ones are grouped on the anterior part of the bar and the short ones on the posterior. The decided curvature of the bar, the absence of a main cusp, and the two sets of delicate denticles characterize this species. Holotype.—Cat. No. 11441, U.S.N.M.

The cusp is slightly extended below the bar into a protuberance. The denticles are very similar to each other and to the cusp in shape. Cotypes.—Cat. No. 11443, U.S.N.M. PRIONIODINA UNDULATA, new species Plate 9, fig. 18 This bar is slightly arched alone the posterior extension, but is sharply deflected at the cusp, forming a right angle. The main cusp is very long, stout, well rounded, and bluntly pointed. The denticies on both sides are similar to the cusp but they are about one-third the size and they vary somewhat as to length. The denticies farthest from the cusp are upright but the nearer they approach the cusp, the more they bend toward this great central tooth. A space a little less than the width of the denticles separates them. Holotype—Cat. No. 11444, U.S.N.M. Genus BRYANTODUS Ulrich and Bassler, 1926 BRYANTODUS INEQUALIS, new species Plate 10, figs. 1, 2 The bar is traversed for half its length by a median ridge. The other half is very flat, curling slightly at the end. A broad, short, sharply po:nted, and slightly recurved cusp rises at an obtuse angle from the center of the bar. The cusp is about four times as broad as the denticles at its base. Posterior to the main cusp the denticles are short and slightly separated. On the anterior side the denticles are about twice this length, although they gradually become shorter as they approach the end of the bar. As the denticles become shorter they are at right angles with the bar, whereas the long ones near the cusp are noticeably curved toward that tooth. The unequal size of the two sets of denticles marks this species. Coty pes.—Cat. No. 11445, U.S.N.M. BRYANTODUS INCLINATUS, new gepecies Plate 10, fig. 3 Tooth triangular in outline, consisting of a broad flat sharp pointed main cusp, inclined to the bar, followed posteriorly by at least 10 28 PROCEEDINGS OF THE NATIONAL MUSEUM vou, 72 slender denticles diminishing in size toward the extremity and ante- riorly by three or four similar denticles. All of the denticles are also blunt and are very much alike except in length. All are inclined with the main cusp. The strong inclination of both main cusp and denticles characterize this species. Holotype—Cat. No. 11446, U.S.N.M. ERYANTODUS GERMANUS, new species Plate 10, fig. 5 The wide, almost fiat bar is traversed for its entire length by a median line The upper and lower portions of the bar thus lie in two different planes. From the center of the upper half a broad angled and strongly recurved tooth rises. On the concave side of this cusp there is a broad, blunt denticle about as long as the cusp. The other denticles vary in length but are of the same general shape. On the other side of the cusp the denticles are longer, flatter, and very sharp. pointed. Narrow but equal spaces separate all of the denticles. Holotype—Cat. No. 11447, U.S.N.M. BRYANTSODUS SUBANGULATUS, new species Piate 10, fig. 6 This narrow bar is very strongly arched or angulated. On one side of the cusp the denticles are much shorter than those on the other side. All of the denticles become gradually shorter toward the ends of the bar. Holotype.—Cat. No. 11448, U.S.N.M.

On the other side it is stout but somewhat flat. Broad, heavy denticles rise from the long side of the bar. The terminal denticle is about as broad as any two of the others. All of the den- ticles are separated by very narrow spaces. There is a wide space on each side of the cusp which is round, very thick, and slightly ex- tended below the bar. On the short side of the bar the denticles are thinner than the others but they are quite substantial looking, They are short and widely spaced. Holotype.—Cat.

Diplododella bilateralis UtRicu and Bassier, Proce. U. 8S. Nat. Mus., vol. ‘68, p. 41, text, fig. 21. The short, narrow, blunt cusp rises from the center of a strongly arched bar, both sides of which are about equal in length. The median ridge, extending the whole length of the bar, divides the bar into two parts which lie in different planes. Beneath the cusp there is a small concave depression. ‘The denticles, which are alike on both sides of the cusp, seem to rise from the median ridge rather than from the edge of the bar. Spaces wider than the denticles separate them. The denticles themselves vary in size; the nearer the ends of the bar, the smaller and thinner they become. Holotype.—Cat. No. 11306, U.S.N.M. Genus HIBBARDELLA Ulrich and Bassler, 1926 HIBBARDELLA CURWVATA, new species Plate 10, fig. 9 _ This is a tiaralike tooth. There are five short, thick denticles with blunt points on each side of a narrow but very robust bar. Very wide spaces separate the denticles. The crownhke appearance is helped by the curved contour of the strongly arched bar. The blunt-pointed cusp is very wide, thick, and long. Holotype.—Cat. No. 11450, U.S.N.M.

Mus., vol. 68, p. 4, pl. 10, fig. 5, text fig. 20. This sharply arched bar is distinctly divided into two parts. On one side of the long, angular cusp which has its origin in the peak of the bar, the round, thick bar bears a number of short, sharp- pointed and well-separated denticles. The other side has the appear- ance of a flat, finely serrated paim leaf. Here the denticles eradu- ally diminish in length from the very long one next to the cusp to the one at the end of the bar which is so minute as to be hardly distinguished from the bar itself. Spaces about the width of very fine hairs separate these denticles. Holotype.—Cat.

The long, stout cusp, tapering to a very blunt point, divides. the bar into two unequal parts. The denticles are merely indicated on the short side of the sharply arched bar. The long side bears a number of long, needlelike denticles. In some places the relatively wide spaces between the denticles are filled with very fine denticles.

SYNPRIONIODINA PLANA, new species Plate 10, fig. 13 The bar is very broad, flat, and strongly arched. A median ridge divides the bar into two parts. The cusp is fiat, very wide, and tapers a little toward a rather wide, blunt point. It is about twice the length of the other denticles, which are similar in shape. The spaces become wider as both ends of the bar are approached. All of the denticles are set at right angles to the bar, which is very long on the steeper side of the arch. This specimen, as well as several others the bars of which are divided by the median ridge, gives one the impression of being one of a series, set in a jaw, as the shark’s teeth are. Holotype.—Cat.

The cusp, which is scarcely different from the other short, blunt pointed denticles, is moderately produced as a flange below the bar. These denticles are all widely separated. The terminal tooth of the long side helps to form a convex end to the bar. Holotype—Cat.

POLYGNATHUS TRILOBATUS, new species Plate 11, fig. 4 As its name indicates this is a distinctly three-lobed plate. The anterior lobe is long and narrow, while the lateral lobes sweep in broad lines from the anterior lobe to the carina. A low median ridge rises in the middle of the anterior lobe becoming flattened towards the top but gradually narrowing posteriorly until it is produced beyond the plate into a broad carina, bearing denticles. The tubercules of the basal portion are stronger and more concen- trically arranged than in Polygnathus concentricus. The tubercules. of the anterior lobe extend from side to side across the top of the median ridge. Holotype-—Cat.

S. Nat. Mus., vol 68, p. 47, pl. 8, figs. 6, 7. The plate is roughly triangular, having three well-defined lobes. The rounded lateral iobes gradually disappear into the sides of the sharp-pointed anterior lobe by means of a shallow, curving indenta- tion. The plate is slightly depressed toward the posterior end but elevated in the anterior lobe. The median ridge, which is low but sharp in the posterior end, extends the entire length of the plate and in the anterior lobe becomes broad, being produced beyond the plate by a carina bearing several round, compressed denticles. Both the median ridge and the carina are somewhat sinuous in their courses. Short tubercules are concentrically arranged in the lobes. In the anterior lobe, where they cross the median ridge, they are so closely spaced as to appear as continuous lines. Compared with Polygnathus tralobatus, this species differs in its more finely marked basal portion and in the extension of the median ridge to the anterior extremity. Plesioty pes —Cat.

Plate rhomboidal in shape. Posterior lobe long and narrow. Lateral lobes slightly broader and somewhat rounded. The median ridge which extends the length of the plate is extended beyond the plate by a short, narrow carina, bearing several denticles, varying in shape and size. These denticles are extensions of those borne on the median ridge. In the anterior end of the plate the ridge is traversed by tubercules concentrically arranged but terminating abruptly at the ill-defined base of the ridge. Parallel rows of denticles extend from the anterior lobe to the origin of the carina, where they turn at a sharp angle and terminate in the margin of the lateral lobes. The rhomboidal shape, less conspicuous transverse ribs, fewer rows of tubercules, and their more longitudinal arrangement, dis- tinguish this species from its allies such as Polygnathus concentricus.

The narrow median ridge which bears denticles throughout its length extends from the anterior end of the plate to the carina, which is slightly deflected. Several stout denticles are borne on the carina. The tubercules on both sides of the plate occur in short parallel lines extending from the margin to a depression at the base of the ridge.

Genus PALMATOLEPIS Ulrich and Bassler, 1926 PALMATGLEPIS INEQUALIS, new species Plate 11, figs. 8-10 This plate is divided into three parts by the unequal bifurcations of the median ridge. The main part of the ridge which is produced beyond the plate by a short, blunt carina, is broad and stout. The branches which are thin and high bear six or seven denticles. The short, blunt tubercules on each section of the plate are generally arranged at right angles to the main ridge or its branches.

The ridge is very low at the anterior end but rises toward the posterior end where it be- comes high and broad. On one side of the plate there is a short, pointed lobe. The relative smoothness of the surface serves to dis- tinguish this species from Palmatolepis perlobata Ulrich and Bassler to which it is related. 3 Holotype.—Cat. No. 11, 460, U.S.N.M.

W. Fousom Of the United States Bureau of Entomology This paper deals with the following forms: THYSANURA. Lepidocampa zetekt, new species. Gastrotheus lepismoideus Folsom. CoLLEMBOLA. Achorutes caecus, new species. Pseudachorutes albipes, new species. Folsomia fimetaria (Linnaeus) Tullberg. Folsomia fimetaria (Linnaeus) Tullberg var. dentata, new variety. Entomobrya cubensis, new species. Lepidocyrtus usitatus, new species. Lepidocyrtus nigrosetosus, new species. Lemdocyrtus summersi MacGillivray. Salina wolcotti, new species. Cyphoderus inaequalis, new species. Cyphoderus similis, new species. Cyphoderus pinnatus Folsom. Though all these forms are of interest because almost nothing has been published on the apterygotan fauna of Central America and the West Indies, some of them are of special interest for other reasons. Thus, Lepidocampa is a little known genus of generalized structure, being essentially a Campodea with scales. Four species of this paper are termitophilous. Three are cavernicolous. ‘Two of the new species, occurring on sugar cane, may be of economic importance. Hight species were collected by J. Zetek and I. Molino, of the Bureau of Entomology. Three forms were received from the Federal Horticultural Board, by whose inspectors they had been intercepted. Two species were collected in Porto Rico by G. N. Wolcott, ento- mologist. The termitophilous species were transmitted to the writer by Dr. T. E. Snyder, of the Bureau of Entomology. No. 2702.—PROcEEDINGS U. S. NATIONAL MUSEUM, VOL. 72, ART. 6 55219—27 1 2 PROCEEDINGS OF THE NATIONAL MUSEUM VOL, 72 Syntypes have been deposited in the United States National Museum, Washington, D. C. THYSANURA Genus LEPIDOCAMPA Oudemans The rare genus Lepidocampa is of special interest on account of its resemblance to Campodea. It differs from Campodea chiefly in having scales; also in the imperfect segmentation of the cerci, and the presence of peculiar frmged pulvilli. In most respects, however, the two genera agree anatomically, except as regards minute details of structure. ue The genus was founded by Oudemans (’90) for Z. weberi, a species from the East Indies. The diagnosis of this species is, by the way, inadequate, being almost entirely generic rather than specific. The same species has been reported by Silvestri (’98, 99) from Argentina, Paraguay, Brazil, and Ecuador; but he finds that to decide whether the species from South America is actually the same as that from the East Indies will require a minute examination of material from both regions. Silvestri (716, 718) afterward recorded ZL. weberi from Ceylon, Sumatra, British East Africa, and German East Africa. Carpenter (716) described Z. fimbriatipes from the Seychelles Islands, properly preferring to hold the species as distinct, for the present. His paper has been very useful in the writer’s study of the morphology of Lepidocampa. LEPIDGCAMPA ZETEKI, new species Plates 1-38, figs. 1-30 White. Campodeiform (fig. 1). Body clothed with scales. Head.—The Y-shaped epicranial suture is conspicuous. Eyes ab- sent. Antennae a little more than half as long as the head and body, moniliform. The number of antennal segments found was as fol- lows: One male, 27; four females, 22, 25, 27, 27, respectively; sex unknown, 27, 30, 26. Segments mostly cup-shaped; first two seg- ments short and broad (fig. 2); terminal segment (fig. 3) only one- fifth or one-fourth longer than the penultimate segment, ovate or oval. Segments 4-7, inclusive, each bear a dorsal pair of bothrio- tricha (fig. 2), which are extremely long, delicate, fringed threads. Segments 5 and 6 each bear, in addition, a ventral or ventro-lateral bothriotrix. Mouth-parts.—The labrum (fig. 4) bears antero-entally a pair of chitinous subtriangular toothed appendages (“unciform processes ” of Silvestri). The head of the mandible (figs. 5, 6) does not have the series of parallel ridges forming a molar area as described by Carpenter, but Ant, 6 TROPICAL AMERICAN APTERYGOTA—FOLSOM 3 bears instead three teeth on one mandible and two on the opposite mandible. | The Jacinia of the mandible also differs from that of Carpenter’s species, being palmately cleft (figs. 5, 6), some of the slender tapering primary lobes bearing secondary teeth. The galea of the maxilla (fig. 7) bears an anterior subclavate sensilla, mentioned by Carpenter. The dacinia is as in Figure 8. The lingua (fig. 9) is rounded anteriorly, with serrate antero-lateral margins. The superlinguae (mawillulae) are not subtriangular as in fimbriatipes, but are (fig. 9) rounded with the mesal margin an- teriorly serrate, the teeth becoming successively smaller posteriorly. Each superlingua bears meso-basally a fingerlike lacinial lobe (fig. 9). The palpus of the labéwm bears an anterior sensory papilla, as in Figure 10. Legs.—The tibia has an apical pair of stout, fringed, articulated spurs (fig. 11). The fringed pulvilli (fig. 12) are essentially like those described by Oudemans and by Carpenter, and quite unlike those figured by Silvestri. Styli—Styli are present on the first seven abdominal segments. Those of the first urosternum differ in form from the others, being (figs. 13, 14) stout, scarcely tapering, blunt, clothed throughout with setae, and ending-in several spiniferous papillae. In the female (fig. 13) there are two simple setae on the mesal side of the base of the stylus. In the male (fig. 14) the stylus is relatively shorter than in the female, and the posterior region of the sternum is thickly clothed with setae; while the posterior border bears two rows of spiniferous papillae. The styli of the remaining segments (fig. 15) are elongate and tapering, each with 5 or 6 setae on the distal half, and a pair of strong spines, apical and subapical, respectively. Hasertile vesicles (fig. 15) are present on the second to the seventh abdominal segment, inclusive. The base of the vesicle is not, how- ever, stiff and cylindrical like that of fimbriatipes. Genitalia—The external organs of reproduction pertain to the eighth abdominal segment. In the male (fig. 16) the eighth uro- siernum is prolonged posteriorly as a broad subtriangular lobe ending in a median rounded setigerous lobe; under the apical portion is the penis, composed of a pair of genital plates, described by Carpenter. In the female (fig. 17) the large sternal lobe terminates in a pair of blunt triangular lobes, each of which bears 4 or 5 setae; under these lobes is a pair of valves (fig. 18), each with 4 or 5 large setae. Telson, cerct—The telson (fig. 19) is subtriangular. The tenth sternum is divided posteriorly along the median line (figs. 20, 21). The anal valves are apparently not strongly developed in this species. Only one intact cercus was present; this being one-third as long as the head and body. The segmentation of the cerci is not definite, 4. PROCEEDINGS OF THE NATIONAL MUSEUM VOL, 72 but the transverse sutures shown in Figure 22 could be seen rather clearly. Clothing —Chaetotaxy is doubtless as important for the separation of species in this genus as it is in Campodea. The macrochaetae are unilaterally fringed or feathered. The head bears numerous short simple setae. The lateral setae of the thoracic terga (fig. 28) are constant in form, size, and position. On most of the abdominal segments there are postero-dorsal setae, as in Figure 24; a little in advance of each postero-lateral angle are two macrochaetae. Beside the base of each stylus is a lateral series of 5 setae (figs. 18, 15); on the mesal side, except on the first abdominal segment, are 6 setae in both sexes *(fig. 15). Near the posterior border of each of the first seven urosterna are two fringed setae, one on each side of the median line, in both SEXES. A comparison of the setal characters shows many differences be- tween this species and fimbriatipes. The thorax and abdomen are clothed densely with scales, dor- sally and ventrally, but scales are almost absent on head, antennae, legs, and cerci. The scales’ (figs. 25-30) are variable in form and size, but are relatively large and mostly broad, with a comparatively few strong striae. Maximum length of specimens: Male, 2.5 mm.; female, 2.8 mm.

The dorsal tooth of the mucro is usually larger than the ventral. Numerous specimens collected on cotton leaves were almost en- tirely yellow. The type material consists of an abundance of specimens collected in Porto Rico by G. N. Wolcott, after whom the species is named. He says that these springtails on corn are moderately abundant on the north side of the island, and on the south (dry) side of the island occur in enormous numbers. 12 PROCEEDINGS OF THE NATIONAL MUSEUM VOL, 72 Porto Rico—Point Cangrejos, February 6, on the ground; Rio Piedras, February 9, 11, 23, on Yautia; Bayamon, February 19, on canna and water hyacinth; Guinica, March 18, on cane; Bayamon, May 5; Isabella, August 1, on cotton leaves; Pefuelas, August 16, on corn. : Synty pes.—Cat.

CYPHODERUS PINNATUS (Folsom) [New combination] Plate 8, figs. 72-17 Borecus pinnatus Fousom, 1923 This variable species was described from British Guiana. My specimens from the Canal Zone agree with the types except in minor details, as follows: The antero-proximal lobe of the unguis is usually smaller than the postero-proximal (fig. 72), though occasionally subequal to the latter, as in the types. At the middle of the inner margin of the unguis is a strong tooth, which is obscure in the types. The outer dorsal pinnae of the dens are 5; the inner usually 4 (sometimes 5 or 6). The inner distal pinna (fig. 73) extends to the second anteapical tooth of the mucro; the adjacent outer pinna (fig. 74) extending not quite so far. The teeth of the mucro (fig. 73) vary from 3 to 9 in the specimens at hand (figs. 75-77) ; an apical and two anteapical teeth being constant. Apical tooth relatively small, usually more or less hooked, sometimes almost straight. Anteapical teeth large, subequal, each giving rise anteriorly to a lamella. In addition to the three primary teeth there may be from one to six small secondary teeth; these occur between the two anteapical teeth, in front of the second anteapical tooth, or in both places. To express the number, size, and position of the mucronal teeth, the following formula may be used, in which the primary teeth are indicated by large numerals and the secondary teeth by small ones, beginning with the apical tooth. Thus the formula for Figure 75 would be 111; that for Figure 73, 1111, In the specimens studied these formulae occurred : Length of speci- Mucronal formula mens (milimeters) BISA EcaCEhT Acie) emai aS Tee Lace Yeas Oe ls a a ONS wae TUT SIU (UTES By Se Oa Ti AI IR otc Ca BO tS om aE a 0.5, 1 SUTL SL ASL 1 (HUES) Z(G) ae ak oS Sn AS Me AN al ea Oe OH SE 0.5, 1 TUAUSL AU SV st et NES Re es CTR EE LP EAT Ut TRON oP Ng NN 1 UHL DST eh i A ae IN tah U SIMRAN SS By aed 1 BISUUitest it at tranny (GL > pened iat) ee ees eh cay STE RRO LANRN Te Vance cera ceri Mae Be CAUDAL I, 1 VILSESUTL ASUS TE ee OE UE SY SS Alt a TA OMA a St Je ee Le tc ac ae A ikea! 14 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 72 This table shows no close correlation between the number of sec- ondary teeth and the size of the specimen as indicated by its length.

M. Aupricu Associate Curator, Division of Insects, United States National Museum The Vienna Natural History Museum contains a large amount of type material in the American muscoid flies. This is principally in the species described by Wiedemann? in 1830, by Schiner? in 1868, and by Brauer and Bergenstamm ® in parts 4, 5, and 6 of their series called “ Zweifliigler des Kaiserlichen Museums zu Wien.” The last-named series contains many new genera based on new species and those of Wiedemann and Schiner. The authorities of the Vienna Museum a few years ago indicated a willingness to lend the American types to this museum for study, and I have availed myself of their liberality so far as to borrow six lots, numbering in all 110 species. I have reported on 79 of these in three articles published in the Annals of the Entomological Society of America.* On account of the magnitude of the project it is thought best to continue it in the Proceedings of the Museum, and the remainder thus far studied are included in the present paper. The study of these types has verified many identifications in the United States National Museum, demonstrated the synonomy of many genera and species, and furnished more complete data than formerly existed for the future identification of a considerable number of species not as yet represented in this museum. 1 Aussereuropiische Zweifliigelige Insekten, 2 volumes. 2 Diptera der Novara Reise, 1 volume, 3 Denkschriften der Kaiserlichen Akademie der Wissenschaften; part 4 is in vol. 56, 1889, pp. 1-180, with 11 plates; part 5 in vol. 58, 1891, pp. 305-446; and part 6 in vol. 60, 1893, pp. 89-240. 4Vol. 17, 1924, pp. 209-218 ; vol. 18, 1925, pp. 107-130,and 456-469.

Two females, both “ Lindig 1864 Venezuela ” and both with label in purple ink, large hand, “ columbiae BB type.” These agree with the description and may be the types although originally the species was said to be from Colombia.

Townsend had identified the species correctly from Panama and Peru in the United States National Museum. I afterwards found a specimen in the collection from Costa Rica. The type and our three specimens are all females. 81. PACHYGRAPHIA VIRGATA Wiedemann Dexia virgata WIEDEMANN, Auss. Zweifl., vol. 2, 1830, p. 382. Pachygraphia virgata BRAUER and BERGENSTAMM, Denk. Wien. Akad. Wiss., vol. 58, 1891, p. 406, vol. 60, 1893, p. 132.—TownsrEnp, Ins. Ins. Menst., vol. 4, 1916, p. 8. Brauer and Bergenstamm in both references included Deaia vir- gata Wiedemann and Deaia fervens Wiedemann under Pachy- graphia. ‘Townsend designated the former as type of this genus. One female “ Brasilien” labeled with genus and species but not the word “ type”; an old specimen with no legs, very few bristles and only one third antennal joint; thorax in bad condition and abdomen roughly glued on. It is possible to ascertain immediately that my genus Camptops® is a synonym of Pachygraphia. The shape of the head in virgata is exactly like that of wnicolor, genotype of Camp- tops. ‘They agree in having one orbital bristle, the vibrissae above the lower edge of the head, and so forth, but vzrgata has quite black palpi as mentioned by Wiedemann. In wnicolor there is a blackish changeable spot in the pollen of the upper part of the parafacial between the second antennal joint and the eye, which is entirely absent in virgata. The plumosity of the arista is longer in virgata and seems to continue to the extreme tip. The parafacial has a few small hairs, not in rows, just about as in unicolor. The only dif- ference I can make out in the chaetotaxy is that virgata has two intraalars, of which the anterior is absent in unicolor. In both there is no postscutellum, the third vein has six widely separated setules reaching nearly to the cross vein; bend of fourth vein rectan- gular with short stump, last section of fifth vein shorter than hind cross vein. In virgata the first posterior cell is narrowly open a little before the tip. The species is not represented in the National Museum. 82. ?

It does not belong to Pachygraphia (type virgata ' Wiedemann) already mentioned, but being in poor condition I will not attempt to establish a new genus upon this specimen. ‘The best that I can do is to mention characters sufficient to identify the species when new material is obtained. Tt is a rather slender, gray fly, nearly 6 mm. long, with a very striking seal-brown stripe on the last three abdominal segments, occupying about one-third of their width. Apparently a similar stripe exists on the thorax, since I can make it out on the scutellum and just before. The remainder of the abdomen is densely yellowish pollinose above; no median marginals on first and second segments; if any are present on the latter they must be very small; third with a marginal row of 6; the fourth has a marginal row of 6; and the fifth has a marginal row of the same number, but no discals what- ever. In the specimen the abdomen is rather flattened and has a sharp margin on each side which seems to be correlated with the color pattern but may be an individual peculiarity. There are only two sternopleurals; no pteropleural; well-developed row of hypo- pleural; only two pairs of scutellar. No trace of postscutellum. The wings narrow, third vein with two minute hairs at base; fourth vein with angular bend which is rather. close to hind margin, ending not very far before tip of wing; last section of fifth vein about one- seventh of the preceding. Head considerably shriveled, the front moderately narrow, apparently without ocellars; frontals extending slightly beyond base of antennae; parafacial rather narrow and apparently bare, the deeply shriveled facial ridges bare; vibrissae at oral margin; third antennal joint narrow, about twice the second, which is swollen toward the tip; arista pollinose to the tip, its ex- treme base enlarged. Palpi and proboscis rather small. Legs black, middle tibia with no bristles on outer front side; hind tibia with one on outer and one on inner hind side at the middle and one above the latter halfway to the base; also one on outer flexor side below middle. The species 1s not represented in the National Museum nor in any other collections that I have seen. 83. CHAETODEMOTICUS CHILENSIS Schiner Demoticus chilensis ScHINER, Novara, 1868, p. 324. Chaetodemoticus chilensis BraurR and BERGENSTAMM, Denk. Wien. Akad. Wiss., vol. 58, 1891, p. 385; vol. 60, 1893, p. 140. One male, “ Novara—R. Chili,” labeled as type of species, which is the type of the genus. Eyes bare, front broad, 0.42 of the head width at vertex, which is not much narrower than the space between the eyes at the vibrissae; two large verticals, the inner especially strong; ocellars stout, divergent and reclinate; frontals about 11, 6 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 72 the uppermost strongly divergent and reclinate, those below converg- ent, the lowest two or three extending down on the face and pro- clinate, the uppermost one of these being at the level of the base of the third antennal joint. About four pairs of proclinate orbital — bristles present, the uppermost small and close to the divergent frontals, the lowest opposite insertion of antennae nearly in line with the proclinate frontals. Parafrontal narrow above, the median stripe very wide; just above the antennae however the stripe is only as wide as one parafrontal. Parafacial moderately wide with numerous smallish black hairs. Cheek about one-fourth the eye height, bare except below and posteriorly. Mouth a hitle protuber- ant so that the length of the head here is equal to that at the inser- tion of the antennae. Facial ridges bare, face flat transversely. Vibrissae at the oral margin arising from a cluster of smaller bristles; antennae fully three-fourths as long as face; second antennal joint about two-thirds as long as the third; arista short, thickened nearly to the tip, the basal joints short. Palpi normal; proboscis short, but quite slender beyond the joint. Back of head a little bulging, with only white hair except the orbital row and a few dark hairs near the mouth.

RHINOMACQUARTIA CHAETOPHORA Brauer and Bergenstamm Rhinomacquartia chaetophora BRAUER and BERGENSTAMM, Denk. Wien. Akad. Wiss., vol. 58, 1891, pp. 373, 380, 404; vol. 60, 1893, p, 134. One female, the type, collected by Natterer at Ypanema, Brazil, and so labeled in abbreviated form. The species is so remarkable that it can not be placed in very close association with any known to me. Brauer and Bergenstamm in 1891 placed it first in Group Pseudodexiidae. Within this group however they have several sub- divisions to which they give the family ending, and they recognize Rhinomacquartiidae for this sole species on page 380; but on page 404 they have “ subgroup Rhinomacquartia ” consisting of this genus with a few others doubtfully added. In 1893, they divide “Sectio Pseudodexiidae ” into 17 subsections one of which is Rhinomacquar- tia, containing only this single genus and species. <As their “Group Pseudodexiidae ” is very heterogeneous, they in effect indicate no close relatives of the present genus. They were puzzled as to the sex of the specimen; the somewhat distorted apex of the abdomen did not seem to show male characters, but the front had no orbitals, so they put it down as a male with an interrogation. I relaxed the specimen and examined the abdominal structure and find it a female. The hypopleural bristles and postscutellum are well developed {I examined the latter while the specimen was relaxed). The arista is plumose above, below and in several other planes; it is hardly longer than the third antennal joint, and curved downward. The eyes are densely hairy. The head is flat behind and elongated forward, the length at antenna and epistoma are the same; this makes the para- facial unusually wide; it is nearly covered with uniform fine hair gradually becoming longer below. The front is quite prominent, broad, apparently without orbitals; ocellars broken off, outer vertical hairlike; the frontals very small above, the row ending at antennal insertion. On one side there is a scar on the parafrontal a little in advance of the anterior ocellus while on the opposite side the cor- responding scar is considerably farther forward. Whether these represent a pair of reclinate verticals or a pair of orbitals I can not tell. Epistoma strongly thrust forward between the vibrissae, the face concave in profile, ridges bare. Proboscis short, fleshy, palpi normal. Third antennal joint with parallel sides, rather elongate, more than twice the second; basal joints of arista small. Micrometer measurements of the head are as follows: width, 55 units; length at antennae, 38, at epistoma the same; height, 48 (eye, 33, cheek, 15); vertex, 16 (or 0.29 of head width). Thoracic chaetotaxy: acrostichal 3 anterior, posterior doubtful; dorsocentral, 3, 4 (the second posterior small and irregularly placed) ; humeral, 4; posthumeral, 2 (the hind one small); presutural, 1; notopleural, 2; supraalar, 3; intraalar, 2; postalar, 2; sternopleural, 8 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 72 2, 1; pteropleural, 0; scutellum with 2 lateral, 1 discal, scars of minute apical pair; prosternum bare. Hind calypter of good size, bare, a group of minute setules beneath it. Abdomen ovate, with weak bristles; none on first segment, second with weak marginal pair, no discals; third with marginal row of 6 rather strong and some irregular bristly discal hairs; fourth seg- ment with marginal row and a few small irregular on disk. Basal sternite visible, the others covered. Middle legs missing, hind tibia with very sparse and irregular cilia. Wing subhyaline, fourth vein a little curved backward, the bend rounded and rather close to hind margin; first posterior cell open only slightly before extreme apex; third vein with 3-5 setules at base, all the other veins bare, including stem vein. No costal spine. Hind cross vein nearly three-fourths of the way from small cross vein to bend of fourth. Head yellow, only the upper two-thirds of back, vertex, arista, and third antennal joint except base, black; cheeks with pale yellow hair, the bristles of epistoma beginning at about the middle. Tho- rax black, rather uniformly cinereous pollinose, scutellum concolorous. Abdomen yellow with median black stripe as wide as the distance between the two largest scutellar bristles; this stripe widens on posterior half of second segment into a flat triangle almost reaching the sides; on the third segment it forms a larger triangle covering all but the outer front part; fourth segment wholly black above except narrow margins. Venter yellow with some brownish stains. Legs yellow except tarsi, which are black. Length, 9 mm. I can find no near relative in the United States National Museum, but I venture to suggest Booponus intonsus Aldrich as neue some similar characters, including bare prosternum.. 85.

There is no reason to doubt that this specimen is the type of lata, although there are slight discrepancies in both existing dlaseaeiens! arT.7 AMERICAN MUSCOID FLIES IN VIENNA MUSEUM—ALDRICH 9 Female——Length, 9 mm. Eyes slightly but perceptibly hairy. Front broad, 0.37 of head width at the vertex, gradually widening as the face also does to lower curve of eye. Pollen of parafrontals, parafacials, and posterior orbit light golden yellow, which, however, does not extend upon the cheek. Middle of face cinereous, the ridges darker and bristly halfway (one side) or more (the other side); cheek one-third of eye height, hairy; proboscis short, fleshy; palpi of usual size, yellow, tips a little swollen. Antennae black, base of third joint reddish; third joint three times the second (not four, as stated by Brauer and Bergenstamm), rather thick at base and dis- tinctly tapering to a small apex; arista bare, its penultimate joint short, thickened to middle. Frontal bristles damaged, only the scars left of many; the usual orbitals are indicated, one ocellar remains, but twisted (?) toward the side. Back of head with white beard, bushy below. Thorax black with bluish-gray pollen; the usual four stripes visible from behind, somewhat coalescing behind suture. Scutellum slightly reddish at tip. Anterior acrostichal 3 on one side, 2 on the other (lacking the one just before the suture on this side). Scutellum with three large lateral, the apical (scars) far apart and strong; one discal scutellar pair. Supraalar 2; sterno- pleural 1, 1 on one side, the other 2, 1, but the lower small. Abdo- men with nearly uniform bluish-gray pollen, becoming distinctly more yellowish on fourth segment; the hair is coarse and almost suberect. First segment with one pair median marginals; second with one pair; third with a marginal row of about 10, and a sub- marginal irregular pair on the middle, too far back to be called discals; fourth segment with numerous erect small and large bris- tles beginning near base. In spite of Weidemann’s statement, the abdomen shows very little tessellation. Legs black; middle tibia with two bristles on outer front side, the lower large; hind tibia with a row of erect almost uniform bristles on the whole length, just below the middle one considerably larger (on one side, the other has two less enlarged at this place). This does not quite agree with Brauer and Bergenstamm. Wing subhyaline, third vein with two small setules at base; fourth vein with oblique rounded bend, ending considerably before apex. The species is exceedingly like Frontina frenchit Williston (syno- nym hesperus Brauer and Bergenstamm, type of Achaetoneura) of the United States, but the latter has bare eyes, four sternopleura.s, three supraalars, and the thira antennal joint is broad to the tip.

One male labeled “ Bilimek, Mexico, 1883,” undoubted type of the species. This is clearly the male of Microchira mexicana, described by Brauer and Bergenstamm on the following page from a female; I have previously reported on this specimen as indicated above. The male differs from the female principally in the shape of the head, having a narrower and much more prominent front and stouter antennae. The frontals extend in an irregular row down the parafacial to the transverse impression, about to the lower curve of the eye, and are considerably larger and more numerous than in the female; the hairs of the upper parafacial and lower part of parafrontal are coarse and bristly. The third antennal joint is considerably stouter than in the female and nearly four times the second. The arista is thickened on the basal two-fifths and dis- tinctly pubescent. As in the female, the pollen of the head, thorax, and abdomen has a somewhat yellowish cast, especially on the lower part of the head and the last abdominal segment. The male differs from the female in having normal front tarsi with moderately elongated claws and pulvilli. The National Museum contains two females of aperta from Fed- eral District, Mexico, collected by E. G. Smyth on August 31, 1922. 87. HYSTRICIA COPULATA Wiedemann Tachina copulaia WIEDEMANN, Auss. Zweifl., vol. 2, 1830, p. 295. Hystricia copulata BRAUER and BERGENSTAMM, Denk. Wien. Akad. Wiss.; vol. 58, 1891, p. 409.—EIncGEL, Zool. Jahrb., vol. 43, 1920, p. 306, fig. The history of this species is very curious. Wiedemann described it from two Brazilian specimens which he evidently believed had been taken in copulation. He noted that the male had a dark face and blackish beard, while the female had a yellowish face and white beard. Both specimens are before me. His male bears a very old label, probably Wiedemann’s, in ink brown with age, “copulata Wied. Brasilien,” also a Brauer and Bergenstamm label, “ Hys- tricia copulata Wied.,” and a red label, “ Type.” The other speci- men, also a male, is labeled “cop. 2 ” in the same handwriting and brown ink as the preceding; also “ Brasilien” a Brauer and Bergen- stamm label “ Willistonia copulata Wied.,” and “ Coll. Winthem.” ART. 7 AMERICAN MUSCOID FLIES tN VIENNA MUSEUM—ALDRICH 11 Brauer and Bergenstamm, 1891, in their systematic list of the ‘material in the Vienna Museum, entered Willistonia copulata Wiede- mann on page 403, and Hystricia copulata Wiedemann on page 409, but gave no indication that these were described as a single species by Wiedemann. The supposed female is a male of a species of Belvosia. Tt lacks the fourth abdominal tergite almost completely, which greatly changes its appearance and misled Wiedemann. There are only one or two narrow vestiges of this tergite present, but they show characteristic dense white pollen; the fifth sternite is present and indicates the male sex, as the absence of fronto-orbitals also does. The male (to which the species is hereby restricted) has been reported upon in detail and the genitalia well figured by Engel. He follows Brauer and Bergenstamm in placing it in the genus Zystricia, and I agree in this. On looking for the species in the National Museum, I found only a single female, which Townsend had placed under a manuscript specific name in his genus Hystriciopsis. ‘This genus was proposed by Townsend ° for the new species obscura, from Peru; the characters were as follows: “Runs to Hystricia in Brauer and Bergenstamm’s tables. May be distinguished by the epistoma being only moderately salient, not nasute; by the thickly haired tegulae, and by the distinctly curvate character of the spinelike macrochaetae.” On comparing obscura with amoena Macquart, the genotype of Hystricia, I find they are just alike in the pilosity of the ealypter, while the other characters adduced seem too slight to estab- lish a genus upon. Hystricia has, among other characters, bare para- facials, pilose eyes, palpi of good size but not excessively developed, lower calypter hairy, with numerous spinose bristles on scutellum and 2-4 abdominal tergites, also a few on the sternites. Hystricia copulata is a smaller species than amoena and obscura. The pollen of the male is spoiled, but in the female in the National Museum it is slate colored on the parafrontals, pale plumbeous on paratacials, face and cheeks; the palpi are almost black, only the tips a little paler; anterior part of thorax with considerable cinereous pollen, becoming thinner toward scutellum, which is shining brown. Calypters dark brown with dense blackish hair. The abdomen is shining brown with some indications of reddish, and in a very oblique view a slight trace of brown pollen. Venter wholly shining. ‘The narrowest part of the front is 0.15 of head width in male, and 0.22 in female. The cheek is about 0.4 the eye height in both sexes. the beard white behind but considerably mixed with black on upper and anterior part of cheek; several rather distinct bristles stand a Ins. Ins.

ZENILLIA THERMOPHILA Wiedemann Tachina thermophila WIEDEMANN, Auss. Zweifl., vol. 2, 1830, p. 325. Sisyropa thermophila BRAUER and BERGENSTAMM, Denk. Wien. Akad. Wiss., vol. 56, 1889, p. 163; vol. 58, 1891, p. 344; vol. 60, 1893, p. 113, 122. One male, “thermophila Wied. Java,” and “Coll. Winthem,” also red “type” label. I asked to see this Java specimen in order to assure myself about the status of the genus Sisyropa, this being the type species. The genus was established by Brauer and Bergenstamm in 1889 (p. 163), with only this species. In 1891 (p. 344), the authors gave a synopsis of a dozen species, from Java, Europe, Australia, and Brazil, prefacing with the remark, “We should probably have done better to unite the species of this genus with those in the genus Parexorista, with which, as also with Chaetolyga, they have the head structure in common.” In 1893, however, they place Sisyropa in the section Blepharipoda (p. 122), and Parexorista in section Masicera (p. 113). Since the standing of the genus depends entirely (aside from questions of priority) upon the characters of the type species, these will be briefly enumerated. The head of the specimen is obviously shrunken, so micrometer measurements are of doubtful value. Male, front moderately wide, face considerably wider but not widening very much below middle; front not prominent, face mod- erately receding; cheek probably about one-sixth the eye height in normal specimen; parafacial bare, very narrow below; vibrissae at oral margin; clypeus wide, facial ridges bristly only one-fifth of the way. Ocellars small, proclinate, parallel; frontals about 10, the uppermost pair large and reclinate, succeeding ones small, then gradually larger near antennae, the lowest almost at level of arista; one or two smallish bristles outside the main frontal row near antennal insertion. Antennae reaching four-fifths of the way to the oral margin, third joint of medium width, a little more than twice the second; arista slender, only a little thickened on proximal half, basal joints short. Palpi normal, proboscis short, fieshy. Thoracic chaetotaxy: acrostichal, 3, 3 (damaged, a little uncer- tain); dorsocentral, 2, 4; humeral, 3; posthumeral, 2; presutural, 2; notopleural, 2; supraalar, 3; intraalar, 3; postalar, 2; sterno- pleural, 2, 1; pteropleural minute; scutellum with 4 lateral, 1 rather large depressed apical, 1 discal. ant.7 AMERICAN MUSCOID FLIES IN VIENNA MUSEUM—ALDRICH 13 Abdomen ovate; first and second segments with one smallish erect median marginal pair of bristles, third with a marginal row of about 12 larger; fourth with erect coarse hairs becoming bristly at hind margin; no discals on second and third, but the hairs on whole dorsal surface are rather dense, evenly placed, and become more erect near the median line. On the venter of the third seg- ment, the inflexed tergite bears on each side a distinct rounded tuft of long hairs. The legs are of ordinary structure, the claws and pulvilli mod- erately elongated; middle tibia with two bristles on outer front side and a smaller depressed one below them. The hind tibiae are obvi- ously ciliated, with one bristle below middle row. Wings ordinary; first posterior cell rather wide open well before tip of wing; third vein with three or four setules at base, the others bare. The species is not represented in the National Museum. The North American species Zenillia eudryae 'Townsend shows hardly a single difference throughout; three instead of four lateral scutellar bristles is the only one I find. Carcelia gnava Meigen of Europe is also closely related, and as the genus Carcelia dates from 1830 it certainly includes Sisyropa as a synonym. Townsend based his genue Oxexorista on eudryae, but later restricted the genotype to a single specimen which he named thompsoni.’ This specimen shows only slight differences from eudryae, hence Oxexorista also becomes a synonym of Carcelia. It was the judgment of Aldrich and Webber ® that Carcelia itself should be a synonym of Zenillia - Robineau-Desvoidy. 89.

The species has been described by Brauer and Bergenstamm and shows few noteworthy additional characters.

Palpi dark yellow, covered with dense black hairs; dorsocentral 3, 4; presutural 2; sternopleural 2, 1; scutellum with 3 lateral, 1 apical decussate and depressed; pteropleural minute. No discals on second and third abdominal segments, on which the dark pattern takes the form of a broad median stripe and a lateral triangle, which is contiguous and does not reach the front edge. The third tergite has no cluster of hairs below. Middle tibia with one bristle on outer front side; hind tibia ciliate; tarsi with long claws and pulvilli.

Wien. Akad. Wiss., vol. 56, 1889, p. 163; vol. 58, 1891, p. 402; vol. 60, 1893, p. 123. One female, “ Brasilien”; an old folded label reads “ xanthocera Wied. Coll. Winthem.” Agrees with description except that the front is cinereous pollinose with dark red stripe, and the antennae are more reddish-brown than reddish-yellow. I believe it is one of the type series, of which Wiedemann had at least two. It is a true Winthemia (syn. Masipoda), in spite of the fact that even under a high power it shows not a single parafacial hair. Other- wise it has the characteristic structure of the genus throughout, in- cluding the tubular ovipositor. The second abdominal segment has a single large pair of marginals; the middle tibia has a single bristle on the outer front side near middle; there are only two sternopleurals. One female in the National Museum, collected at Bartica, British Guiana, June 7, 1901, agrees remarkably throughout except that under a high power it shows two or three pale slender hairs on the parafacial. Provisionally I regard this as the same species. Only the discovery of the male can clear the species up any further. 92, URAMYIA PRODUCTA Robineau-Desvoidy Uramyia producta ROBINEAU-DESvoIDy, Myodaires, 1830, p. 204.—BRAUER and BrrcrNstTamMM, Denk.

The specimens agree exactly with those identified by Townsend in the National Museum, and discussed by me.® GYMNOSTYLIA Macquart The status of this genus requires elucidation before proceeding to a discussion of the three species received under this generic name. Macquart described the genus in his Histoire Naturelle de Dip- téres.1° He included three species from Robineau’s Myodaires of 1830—Wacromya depressa, Harrisia scutellaris, and in a separate division with tomentose arista Leschenaultia cilipes. These were all Brazilian species. No genotype was indicated until 1916, when Townsend “ designated Macromya depressa. On the same page he designated the same species as genotype of Macromya Robineau- Desvoidy 7? which originally contained this and one other Brazilian species. Thus Gymnostylia is a complete synonym of Macromya. The genotype of the latter, depressa, is totally distinct from anything placed in Gymnostylia by Brauer and Bergenstamm. It is a very large, robust, depressed, yellow species, 16 to 18 mm. long, which I have not seen and am unable to place from the meager description (Macquart’s description is compiled from Robineau’s). 938.

Acrostichal, 3, 8; dorsocentral, 38, 3; sternopleural, 2,1. Mesonotum with rather dense yellowish pollen on which are two pairs of shining black stripes, the outer broader and interrupted. Abdomen rather narrow, with basal crossbands of yellowish pollen on second, third, and fourth segments, which occupy nearly half the length, are slightly interrupted at median line, and bear numerous small black dots from which the hairs arise. No discals even on the fourth segment, one pair median marginals on first and second segments, a marginal row on third and fourth. Third seg- ment with no matted or clustered hair on ventral side. A trace of yellow ground color on sides of second segment. Leys black. claws and pulvilli moderately elongate; middle tibia with one bristle on outer front side, hind not ciliated. The species hardly differs from variabilis except in having fully the posterior half of abdominal segments 2, 3, and 4 shining, while In variabilis the pollen covers all except a narrow hind margin.

One female, “Brasilia,” “longiseta Wd. coll. Winthem,” and B. B. label. Undoubtedly the type, as the plumosity of the arista is matted together by treatment with a solution as Wiedemann says. A second specimen, a male, is erroneously labeled zcterica, but does not agree with the type of that species; it is also from Brazil and in “ coll. Winthem.” The genus Chaetona was established by Van der Wulp (see above) for this and another species. Coquillett designated longzseta as the genotype in his Type Species (1910, p. 521). A female in the Na- tional Museum from Caura Valley, Venezuela, was correctly identi- fied by Townsend; and I have lately added a male, collected by me at La Providencia, Siquinala, Guatemala, April 16, 1926. Van der Wulp’s description and figure are very recognizable, but he shows the abdomen too broad near tip, and the profile shows the front too prominent and bulging. The exceptionally long arista with short, delicate plumosity is a very striking character. 97. CHAETONA ICTERICA Wiedemann Tachina icterica WIEDEMANN, Auss.

Undoubtedly the types. The genus was established by Brauer and Bergenstamm (1891, p. 339) for this species and two others. Townsend designated macilenta as type in 1916,1* carrying out the apparent intention of the authors, who mentioned only this species in their 1893 paper (p. 120).

The lat- ter mention the female, with flattened fore tarsi and smaller ocellars than the male; I do not have this sex. Male—Front at narrowest (vertex) 0.23 of head width. Front a little prominent, slightly shorter than face, which is receding. Head wider than high (48 to 37); vibrissae at oral margin; facial ridges bristly about half way; frontals descending to middle of sec- ond antennal joint; no orbitals; frontal stripe wide. Parafacials bare and silvery. One large pair of frontals reclinate; ocellars large, proclinate. Antennae long, third joint broadest in middle, three to four times the second; arista with basal joints short, slightly thickened for one-fifth its length. Palpi normal, yellow; proboscis fleshy, short. Back of head slightly bulging. Thorax somewhat damaged in both specimens, the disk nearly all black with broad white lateral border before wings. Pleurae almost silvery.

Post scutellum and hypopleurals well developed. Calypters moderately large, pure white: Abdomen narrow, shining black, the first segment nearly as long as the sec- ond; second and third with broad basal silvery band, including about half the segment above, less below; fourth segment wholly shining black. First segment with a pair of large strong median marginals; second the same; third with marginal row of same, but the median pair, as in the preceding segments, is not very close to hind margin; fourth segment with a marginal row placed as on third. The larger bristles of thorax and abdomen are flattened longitudinally at base, giving them a very stout appearance. There are no true discals on the abdomen. Legs black, rather stout, front tarsi unusually so; all claws and pulvilli elongated. Middle tibia with three bristles on cuter front side, the intermediate largest; hind tibia with a few irregular bristles on outer side. Wing noticeably brownish, more so along veins, tips rounded, first vein hairy on its middle third, third vein hairy almost to small cross vein; bend of fourth vein oblique. slightly rounded: first posterior cell open in margin rather far before apex; third vein un- dulating beyond small cross vein, widening the first posterior cell near its middle. art.7 AMERICAN MUSCOID FLIES IN VIENNA MUSEUM—ALDRICH 2] The genus differs from Phorocera in having the head more rounded, first vein hairy, and abdomen narrow. The female prob- ably has a piercer, as Brauer and Bergenstamm say the venter is “stufig” (in steps). The genitalia (fig. 1) are much like those of Phorocera (Huphoro- cera, Neophorocera) claripennis Macquart, of the United States; the united inner forceps form a convex disk basally with a slight, shining median ridge, the apex drawn out into a slender process shightly curved up; the outer forceps are reduced to flat plates. Both pairs brown in color. The fourth abdominal segment is greatly shortened below, the sternite small and almost invis- ible. Not in the National Museum. Fig. 1.—NEOMINTHO MACILENTA WIEDEMANN 99.

Speci- mens received later are from Maryland, Oklahoma, and Cordoba, Mexico. Since Schiner mentioned only a female in the original description, it might be thought that neither of the Brazilian specimens received from the Vienna Museum could be the type. How- ever, it seems clear that Schiner made a mistake regarding the sex. He gives the length as 15 mm., agreeing with these males, while in this species the female has a shorter abdomen, our single specimen of this sex measuring only 9mm. The description of coccyz is accessible and need not be repeated, but I add a figure of the unique genitalia Fic. 2.—PHOROCERA HEROS SCHINER 22 PROCEEDINGS OF THE NATIONAL MUSEUM vou. 72 (fig. 2, drawn by my colleague, C. T. Greene). I see only two slight points of difference between our northern males and the Brasilian ones—the latter have two small bristles outside the lower ones in the frontal row, as mentioned by Schiner, and they also have a somewhat narrower and more sharply limited basal pollinose crossband on the second and third abdominal segments. I do not consider these differ- ences sufiicient to maintain even a varietal standing for coccyz. 100. PHOROCERA BISERIALIS Schiner Phorocera biserialis ScHinER, Novara Reise, 1868, p. 326. Ctenophorocera biserialis BRAUER and BERGENSTAMM, Denk. Wien. Akad. Wiss., vol. 58, 1891, pp. 342, 402. One male, one female, “S. Amerika” and “Rio de Janei”, both with puparia as indicated by Schiner. Since Schiner referred the species to Phorocera, it is necessary tc find out why Brauer and Bergenstamm placed it in a different genus. Ctenophorocera was proposed by Brauer and Bergenstamm in 1891, and four species were placed in it—Tachina experta Wiedemann, from Cape of Good Hope; Phorocera biserialis Schiner from Brazil; Tachina munda Wiedemann, from Tranquebar; and blepharipus, new species, from Cape of Good Hope or Brazil. In 1893 (p. 84) they removed munda Wiedemann to Achaetoneura, remarking that the eyes were almost bare. In the same year in the keys they placed the genus Ctenophorocera, on page 119, in the Group Phorocera and ox page 121, in Group Blepharipoda, both times referring directly to experta as if it were type. Townsend ?® designated experta as type. I asked to see only the American species biserzalis and the possibly American one blepharipus, which are before me. Unfortunately I did not ask for the type species of the genus. I have, however, compared the two I have with the generic de- scription. The characters possibly differentiating the genus from Phorocera (type assimilis Fallen) are three. First, the row of bristles extending up each facial ridge is accompanied on the outer side by a row of hairs. It requires only an examination of a dozen or so of related species to see that this has very slight value. Second, the length of the head at vibrissae is almost equal to that at an- tennae; in other words the face is hardly receding. This is true of dlepharipus but certainly not of béserialis. The American genus Murdockiana might be considered here, but it has the epistoma strongly jutting forward between the vibrissae, unlike blepharipus. The third character is the ciliation of the hind tibiae, which is present in both of the species before me. This is » character which is best developed in males, runs through all possible degrees, and its 16 Ins, Ins. Menst., vol. 4, 1919, p. 7. art. 7 AMERICAN MUSCO7" FLIES IN VIENNA MUSEUM—ALDRICH 23 validity, never high in. this group, depends on the absence of con- necting forms in the particular small series under consideration. Not having the genotype of Ctenophorocera at hand, I can express no positive opinion of the genus, but I would put béserialis back in Phorocera, where Schiner described it.

The ground color of the front is black, heavily overlaid with yellow pollen. The median stripe is brown, almost as wide as either parafrontal. Verticals one large and one small; frontals about six, the upper two pairs represented only by large scars, probably reclinate, the next ones much smaller, decussate, one pair large just at the root of the antennae, and one pair below these. The parafrontals are rather densely covered with short black hairs, which below the upper orbital are proclinate, but above it are recli- nate, while near the median stripe they are directed toward the mid- dle line. This peculiar arrangement of hairs I have never seen in any other species, and it is rather noticeable. Parafacial and poste? rior orbit, except the upper part, bright silvery pollinose; the former eradually narrowing to almost the level of the vibrissae, where it is about as wide as the third antennal joint. Antennae black, rather brownish at base; third joint decidedly slender and about three and one-half times as long as the second. Arista bare, very thin on the apical half, the basal third slightly thickened. Facial ridges with hairs and small bristles extending more than one-third of the way to the root of the antenna.

They are labeled “Lindig 1864 Venezuela.” They agree with Macquart and Schiner accounts, but are not types. The species is the type of Aporia Macquart, but that name was preoccupied. Townsend proposed to change it to Veaporia**; as this was later discovered to be preoccu- pied also, he changed it to Paraporia." The species is not represented in the National Museum. The specimens are not of the same species as those in the National Museum determined as guadrimaculata and so accepted by me.1® These latter (two males) are much more like Uramyia, having an equally long but somewhat broader abdomen; they have on the second and third abdominal segments a large dark triangle with its trun- cated apex touching the preceding segment, leaving a cinerous spot on each side at base; these spots are not widely separated, and fade posteriorly, the rest of the dorsum of the segment being more or less reddish. The true guadrimaculata, agreeing with Macquart’s description and figure, is the species from Vienna; it has a much wider and shorter abdomen, velvet black in color, the two pairs of spots farther apart, smaller and much more sharply outlined. It is this form which is the genotype of Paraporia; there is no doubt of this, as Townsend proposed NVeaporia long before he had seen a specimen, and it merely replaced A porta, to be itself replaced by Paraporia. Neither genus was based on the specimens now in the National Museum. In this sense I think the genus Paraporia is a valid one, although in 1921, supposing the specimens in the National Museum to be of the type species, I placed it as a synonym of Uramyza. The species which was called guadrimaculata by me in 1921 I would now call Uramyia acuminata Van der Wulp, which I errone- ously placed as a synonym. 16 Muscoid Flies, 1908, p. 67. 17 Ent. Soc.

They agree with Van der Wulp’s figure in Biologia except that he has the vibrissae too high up. There is a distinct costal spine, as noted by Townsend. The Na- tional Museum has ten specimens of both sexes; from Guatemala (Aldrich), Vera Cruz (Townsend), Florida, and Colorado, the last identified by Brauer and Bergenstamm. Coquillett made dives a synonym of liturata Olivier, which I believe on examining the orig- inal description is no doubt correct. The female has the front shining, precisely as Van der Wulp indi- cates for his species pulchra; apparently he mistook some males of dives as females, as he says in this species the female does not have orbitals as it does in pulchra. It therefore seems certain that pulchra is asynonym. Dives is the genotype of Euantha. 105. EUANTHA AUCTA Wiedemann Dexia aucia WIEDEMANN, Auss. Zweifl., vol. 2, 1880, p. 377.

The species differs from Utwrata in having no yellow in wings, gen- eral darker color, and legs black except at bases of femora. The front of the female is wholly pollinose except a small area including the bases of the orbital bristles.

Agrees exactly with Wiedemann’s description; the specimen is characterized by a very peculiar wing, reproduced in Figure 3, which has been carefully drawn by C. T. Greene. The apical half of the wing is remarkably elongated, and there is a marked although ant.7 AMERICAN MUSCOID FLIES IN VIENNA MUSEUM—ALDRIOH 29 slight concavity in the costa before the extreme apex; the third vein has only one bristle at base above and below. The species is not represented in the National Museum, although Dr. C. H. T. Town- send had identified a closely related form with less elongated wing as “ egues subspecies with golden squamae.” Mr. Malloch had named the same species Morinia longitarsus Wulp, but I do not think it fits the description very well. The color of the thorax is sharply divided at the suture, being golden in front and dark brown behind. The slender abdomen is subshining black, with silver fasciae at base of second and third segments, narrower across the dorsum but broad laterally; the fourth segment is wholly silvery except a narrow black tip which bears a considerable tuft of bristles. There are no discals on the second and third segments. The first segment is uncom- monly long, exceeding the second, but has no median marginal bristles; the second has one pair and the third a row of about six; the fourth has no discal bristles. Fig. 3.—PSEUDODEXIA EQUES WIEDEMANN The head is almost circular when viewed from in front and the antennz attached slightly below the level of the middle of the eye, the third joint slender, over three times the second; arista rather short-plumose almost to its tip. Front golden pollinose almost to the antennae, at narrowest hardly wider than ocellar triangle, the frontal bristles beginning at the narrowest place and barely reaching the base of the antennae; parafacials narrow, silvery; vibrissae at margin of mouth, a few small bristles extending up almost halfway on the facial ridges; face rather flat and considerably receding; palpi normal, yellow; proboscis small, fleshy. Thoracic chaetotaxy so badly damaged that it can not be made out. Hind calypters very large, postscutellum and hypopleurals present. Legs black; middle tibia with two bristles on the outer front side; hind tibia with a partial row of quite small bristles on the outer hind side, one below the middle a little larger, standing directly opposite to one of equal size on the inner hind side. Claws and pulvilli elongate. 30 PROCEEDINGS OF THE NATIONAL MUSEUM vou. 72 Length of body, 8.4 mm.; of wing, 10 mm. Undoubtedly the female would have a normal or nearly normal wing. 107.

The specimen is in fine preservation and one would hardly think it could have ever been seen by Wiedemann; it does not look old enough and the pin looks modern. (It has not been repinned.) However, being irom Brazil and agreeing exactly with the Wiedemann description, it is undoubtedly authentically determined. Width of front 0.25 of head by micrometer. Ocellars proclinate, parallel, not very large, one broken off. Frontals 2 reclinate, about 11 decussate, some small, just outside middle of row, inclined mesally. Lowest frontal at level of tips of second antennal joints, below it only 2-3 very minute hairs. Parafrontal lead colored, densely polli- nose; parafacial pure white, not silvery; transverse impression and lower posterior orbit the same; cheek with black hairs nearly to eye and covered with very dense long white pollen, the little white scales suberect and distinct under high power. Antennae black, the third joint a little more than twice the second, moderately slender, not reaching vibrissae; arista rather long, evenly tapering, basal joint short. Palpi yellow at least on apical half. Back of head white pollinose and pilose with one row black above and 2-3 below. One pair of verticals, not decussate, reclinate. Facial ridges with coarse erect bristles not quite to the level of lowest frontal. Thorax thinly slaty or plumbeous above to scutellum, the latter brown.

Can not see under calypter, which is brown but not so dark as scutellum and abdomen. Abdomen uniformly brown, subshining, first segment with row of small spines along middle of hind edge, hardly noticeable; second segment with about a dozen small erect blunt spines along the middle region and four larger on hind edge (2 pairs) a wide space between these and the lateral one; third segment with a few very irregular discal erect spines, longer than those on second and confined to posterior half of segment; hind edge with row of stout, blunt spines about as long as the segment. The hair of the segment is more dense and erect at each side behind middle but does not form a matted patch below, though it is dense there; fourth segment with erect bristles all over, those on disk more spiny, at apex with only small bristles; genital segments brown. Prosternum with soft dark hair, a deep depression in its middle. Legs black, pulvilli yellowish-brown, rather long on all tarsi; middle tibia with row of about four long bristles on outer front side; hind tibia with characteristic large row of flattened hairs fringing outer hind side. Wings brownish, especially at base; epaulet and subepaulet brown; third vein with 2-3 hairs. Length, 14 mm. The species is represented in the National Museum by a series of specimens, collected in Panama, Guatemala, and northward to Massachusetts. 108. SPALLANZANIA AMERICANA Schiner Cnephalia americana ScHINER, Novara Reise, 1868, p. 327. One female “ Novara R. Chili,” the undoubted type of Schiner, agreeing with the description and having the abdomen damaged in the same way. This is a true Spadlanzania. It is well described by Schiner and I add only a few items. The vertex is 0.41 of the head width, the eyes diverging only a little and slightly converging again at the lowest part. The ocellar bristles are broken off but without much doubt they were reclinate. The bristles of the front are also mostly broken off, but the scars show two or three rows, the outer quite irregular; the parafacial has a row of about five rather strong bristles nearly in the middle, the space between them and the orbit bearing coarse hairs, but between them and the facial ridges the surface is bare. The pollen of the head is silvery when viewed from in front, with irregular blackish pollen along the orbits above; when viewed from above, however, the parafrontals appear black almost to the level of the antennae. 32 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 72 In an oblique side view a silver streak passes from the antennae to the orbit bordered above and below by blackish streaks; the antennae and. palpi are black, the facial depression is rather shallow and the ridges have only four or five small bristles above the vibrissae. The length of the head is the same at the antennae and at the vibrissae (45 units), not including the epistoma which juts farther forward; the height of the head is 55 units. The second antennal joint is 11 units long and the third 16. The thorax is very distinctly striped, the abdomen mostly shining black with distinct median pollinose vittae; the apical third of the fourth segment is orange red in color, more conspicuous at the extreme tip beyond the small bristles. There are four sternopleurals on one side, three on the other. Length, 10 mm. Not in the National Museum. 109. BELVOSIA ESURIENS Fabricius Musca esuriens Fapricius, Syst. Antl., 1805, p. 301.

Wiss., vol. 56, 1889, p. 97; vol. 58, 1891, pp. 349, 403; vol. 60, 1893, pp. 123, 204. Two males from Brazil, both “Coll. Winthem.” and bearing the small, square red tag without writing, which Brauer says indicates Wiedemann’s original specimens. One is labeled “esuriens Wd. (Fab. ?)” on a very old label; the other has a B. B. label “ Wallistonza esuriens Wd.” Neither of these can be a Fabrician type, as the Winthem Calle tion contained none. The two specimens unfortunately are not of the same species, and it becomes a serious question whether either can be regarded as an undoubted esuriens. Wiedemann apparently saw the Fabrician type when he redescribed the species; his first specimen mentioned above fits his own and the Fabrician description better than the second, and in spite of the question mark I think it must be regarded as the authentic specimen. It has the two whitish abdominal! crossbands as mentioned by Fabricius, and the one on the third segment is obviously interrupted as mentioned by Wiedemann. I therefore describe this specimen as the true esuriens, since there are probably no Fabrician specimens in existence. Male (Wiedemann erroneously calls it a female). Front at vertex 0.31 of head width; the eye rather broadly rounded above so that the narrow part continues a little forward from the ocelli then rapidly widening; parafrontal with three very irregular rows of bristles inclined toward the center, the pollen gray becoming very thin toward the vertex. Face and parafacials pure white, the latter somewhat silvery; hairs below the lowest frontals black, in certain art. 7 AMERICAN MUSCOID FLIES IN VIENNA MUSEUM——ALDRICH 33 lights two or three may have a pale reflection; cheek white pollinose and with white hairs among which three or four are black. Cheek two-fifths of the eye height. Vibrissae almost the length of the second antennal joint above the oral margin; facial ridges with seven or eight strong bristles, the row almost reaching level of arista; third antennal joint three times the second, which is brown in color; palpi yellow. Thorax black with thin gray pollen anteriorly; the scutellum subshining with a brown tinge. Calypters decidedly brown. Sternopleurals 4. Abdomen black, subshining; second segment with narrow basal band of light yellow pollen; third segment with a distinctly inter- rupted band of almost white pollen covering a little more than the basal half and extending on the venter; fourth segment decidedly pollinose except the tip where the bristles arise which is black; there is also a slender black median line scarcely interrupting the pale pollen. First and second segments with one pair of median mar- ginals; third and fourth with a marginal row. Legs black, the front claws and pulvilli elongated, the latter slightly longer than the last two tarsal joints. Hund tibia with sev- eral rather large suberect bristles on the outer side on the upper half, the lower half with uniform row of smaller bristles. All these bris- tles stand along the outer side of some more depressed hairlike ones. Wings rather light brown in color, narrow toward apex, bend of fourth vein rectangular but rounded, a little nearer the margin of the wing than usual; base of third vein with three or four hairs. Length, 11.5 mm. Four specimens of this species, a male and three females, have been received from the American Museum of Natural History; they were collected at Chapada, Brazil, by H. H. Smith. The male has a longer third antennal joint and a narrower band on the third abdominal segment than the Vienna specimen, but the females are like the latter. The second specimen received under the name of eswriens will be included as a paratype of a new species, in a revision of the genus soon to appear. 110, BELVOSIA POTENS Wiedemann Tachina potens WIEDEMANN, Auss.

In this specimen the reddish ground color of the parafacials, facial ridges, and cheeks shows through to a noticeable extent and the suture is distinctly bordered with a darker tinge to its lowest end. Frontal bristles in a single row, the hairs below the lowest are black, as are also the hairs of the cheek. Face considerably depressed in the middle, the vibrissae about the length of the second antennal joint above the oral margin; facial ridges with well-developed bristles up to a point above the middle of the third antennal joint. Antennae black, second joint more dark brown, with a tinge of red at the junc- tion with the third, which is three times as long as the second and a little tapering. Palpi dark yellow, cheek almost half the eye height, beard white. Thorax brownish black with usual thin pollen more distinct in front. Scutellum brown, with four pairs of bristles, the median pair of the same appearance as the others. The disk has about a dozen depressed small bristles. _Calypters brown. Sternopleurals 4 on one side, 5 on the other. Abdomen black, with faint reddish tinge at the sides; third seg- ment with only a very narrow basal interrupted, white, pollinose, crossband, hardly more than a line; fourth segment with dense pale yellow pollen, the apical third black. Legs black, front pulvilli slightly longer than last two tarsal joints; hind tibia on outer side with a row of small, suberect bristles mixed with a few hairs not so bushy in appearance as in many species. Wing brown throughout, narrow at apex, bend of fourth vein rec- tangular and rounded, its distance from the hind margin less than half of that to the large cross vein; third vein with two bristles. Genitalia smaller than in most of the species, the inner forceps black, closely pressed together near tip and bent forward almost with an angle; outer forceps hardly so long, dark yellow in color, flat and bluntly rounded at tip. Length, 10 mm. Represented in the National Museum by two females from Ypi- ranga, Sao Paulo, Brazil (“ Fonseca leg.”). In these the single row of frontals is as characteristic as in the male, and they have four proclinate orbitals in a row, rather far from the eye. The pollen on the parafrontal becomes very thin or almost absent on an oval area that does not include the frontals but touches the eye near the vertex; this area is more or less subshining black, but less in one specimen than the other. The vertex is 0.40 of the head width, the same in both. art. 7 AMERICAN MUSCOID FLIES IN VIENNA MUSEUM—ALDRICH 3835 SUMMARY OF CHANGES OF NOMENCLATURE PROPOSED NEW GHNUS Pammaerus for Gymnostylia leptotrichopa Brauer and Bergen- stamm.

Fenton Entomologist, United Siates Bureau of Entomology, Florence, South Carolina In the following paper are presented descriptions of 23 new species and one new variety of parasitic Hymenoptera of the sub- family Anteoninae. Most of the material studied was from the miscellaneous collection of the U. S. National Museum, and was collected in the New World. Reference to Kieffer’s keys is made in many places throughout this paper. The keys referred to are those published in Das Tierreich, family Bethylidae (vol. 41, 1914). LESTODRYINUS DICHROUS, new species Because the parapsidal furrows are greatly reduced, this species traces to Neodryinus in Kieffer’s key. It is placed in the genus Lestodryinus because it agrees with all the characters of this genus except the reduced parapsidal furrows. Female—Length 6 mm. Color testaceous and black as noted below. Head testaceous, broader than long (13:7); vertex concave, surface with fine longitudinal striations; lateral ocelli located far back on vertex almost to occiput and are approximate, anterior ocellus distant from these, being near frons; head not produced beyond the eyes; occiput truncate; antennae testaceous, third joint unusually long, being more than twice length of scape and second together, and almost three times length of fourth; fifth same length as fourth, thickened distally; sixth to ninth each somewhat shorter than preceding; tenth not quite twice length of ninth. Prothorax testa- ceous, shining with series of fine transverse striations and a fine thick whitish pubescence; mesoscutum and secutellum black, coarsely rugu- lose with distinct short white pubescence; postscutellum black with same sculpturing as scutellum, except a smooth area on the disk; legs testaceous, except hind coxae and small areas on middle and hind femora, which are black; chela with median arm. extending to second tarsal joint, lamellate at tip and a double row of lamellae extending from here to articular cavity, claw nearly parallel sided and straight except at the tip where it is sharply bent, provided with a single row of toothlike lamellae from near articulation with median arm to subapical tooth; wings with subcostal, median and submedian cells, bifasciate, the larger band extending transversely across the No. 2704.—PROCEEDINGS U.

M. Atprica Associate Curator, Division of Insects, United States National Museum The present paper contains two new species of the genus Lasia from Costa Rica, and a new genus and species from the Philippines. LASIA COLEI, new species Male.—Length, 12.5 mm. Bright metallic green; posterior part of abdomen more coppery. Legs black, tarsi pale yellow. Head flattened in front; eyes densely covered with hight yellow pile; back of head and ocellar triangle shining green, the latter not elevated but with two large and distinct ocelli. Eyes contiguous to the middle of the head in front, where the antennae are situated; these are small and slender, second joint except base and small por- tion of the base of the third joint yellow, remainder of third joint black, its tip sharply pointed. Proboscis when folded back slightly longer than the abdomen; no visible palpi. Pile of thorax yellow, rather dense, with some black hairs on the posterior part and on the scutellum. Abdomen in side view with erect black pile on the posterior part of segments one to four. This pile scarcely shows at all in the direct view. On the anterior portion of these segments there is some yellow pile which is continuous along the sides. Venter blue and violet with distinct pale hind margins of the segments; coxae shining green. Calypters with dense yellow pile, subhyaline in the middle with blackish rim. ~ Wing light brownish, the first and second veins coalescent before their tip; the petiole is joined at right angles just at the costa, by the upper branch of the fork of the third vein; the second and third branches of the fourth vein reach the margin. Halteres with brown - knob crossed by a yellow streak. No. 2705.—PROcEEDINGS U. S.

No. 40392, U.S.N.M. The species differs from fletti and scribae in having the tarsi light yellow, but resembles them in the venation. LASIA ROSTRATA, new species Male—Length, 8.5 mm. Color golden green, the humeri and scutellum more coppery. Head convex in front, the vertical triangle coppery; without ocelli. Antennae black, the third joint blunt, distinctly yellow at extreme base; eyes with long pale pile. Thorax densely covered throughout with furry light yellow pile through which the ground color is visible rather indistinctly. Abdomen golden green; first three segments with pile similar to that on the thorax, but a little deeper yellow on the sides of the segments tending to become brown. Last segment with long, silky, pale yellow hairs, especially on the sides. Front coxae green; femora and tibiae dark brown; knees and tarsi yellow. The femora and tibiae are covered with almost white pile. Calypters translucent light yellow with yellow rim and covered with dense pale pile. Wings hyaline, first and second veins joining the costa separately; the anterior branch of the third vein joins the costa distinctly be- yond the second vein; so that the venation is like the figure given by Wiedemann for splendens.+ The proboscis is remarkably long, so that it projects behind the abdomen about two-fifths of its own length. Described from one male, collected at Higuito, San Mateo, Costa Rica (Pablo Schild). Type.—Male, Cat. No. 40393, U.S.N.M. This species agrees so well with Wiedemann’s description and figure of splendens that I would have identified it as that species if I could have seen anything corresponding to the thoracic stripes which Wiedemann mentions and figures. They are entirely absent on this specimen. A female specimen from the same place and taken by the same col- lector agrees in most characters, including head structure and vena- tion. The proboscis, however, is much shorter, projecting only a little beyond the tip of the abdomen; while the ground color of the abdomen is blackish with very little metallic refiection; the pile of the abdomen is largely dark brown. Although it is probable that this belongs to the same species I did not venture to label it as the allotype. 1 Auss.

O ADDITIONS TO THE UPPER CRETACEOUS INVERTE- BRATE FAUNAS OF THE CAROLINAS By Lioyp W. STEPHENSON Of the United States Geological Survey INTRODUCTION The marine invertebrate Cretaceous faunas of North Carolina, with the exception of those of microscopic size, which have not yet been studied, were described in the fifth volume of the North Caro- lina Geological Survey, issued in 1928.1. A few species from the ad- joining State of South Carolina were included in the descriptions. Since the appearance of that volume additional material has be- come available from two localities, one in North Carolina and the other in South Carolina. The collection from North Carolina was obtained in 1923, at the new Rocky Point quarries, a mile northeast of Rocky Point station, Pender County, by Dr. L. B. Kellum, who was then engaged in a field study of the Eocene and Miocene fossil faunas of the eastern part of the State, and by me in 1926. This quarry is not identical with French Brothers’ quarry at old Rocky Point, on Northeast Cape Fear River, 3 miles east of Rocky Point station, where the earlier Rocky Point collections were made. Kellum did not furnish a detailed description of the section in which these fossils were found, but he reported that they were con- tained in a loose sandy matrix in the uppermost layer of the Peedee formation. The Peedee formation (Upper Cretaceous) of this gen- eral area, as shown by the quarries at Castle Hayne and at old Rocky Point, is unconformably overlain by the Castle Hayne marl, a forma- tion of Jackson Eocene age. When I visited the new quarries in May, 1926, they were not in operation and the pits were filled with water so that the section could not be examined. Both the Peedee 1The Cretaceous formations of North Carolina: North Carolina Geol. and Econ. Survey, vol. 5, 1923; Stephenson, L.

The most abundant material was gray, calcareous sandstone of the Peedee formation, containing many fossils preserved in part as the original shell material, such as the oyster, in part in the form of finely granular dolomitic calcite, of which some of the specimens of Cardium, Crassatellites, and Veniella are examples, and in part as interior casts and exterior molds. Fragments of coarse conglomer- ate consisting chiefly of phosphatic pebbles in a glauconitic sand matrix were common and these were obviously taken from the basal conglomeratic layer of the Castle Hayne formation. On sev- eral of the dumps were fragments of hard white limestone and masses of loose crumbly marl containing bryozoa, echinoids, and pectens, and these materials were derived from the Castle Hayne marl above the basal conglomerate. The collection includes two heretofore undescribed echinoids, seven new pelecypods, two new gastropods, and more perfectly preserved specimens of one pelecy- pod, Cardiwm (Trachycardium) penderense Stephenson, described in the volume to which reference has already been made. ‘There are also pelecypods and gastropods too imperfectly preserved for specific identification, some of which probably belong to undescribed species.

The South Carolina locality is Mars Bluff on the right side of Peedee River, 3 miles below Peedee village (Atlantic Ge Line R. R. bridge), Florence County.

With the exception of the new species, Cardium (Trachycardium) marsense, all of the specifically identified forms in the list occur in the Snow Hill marl member of the Black Creek formation of the Carolinas, and even the new species may be represented there by imperfectly preserved molds and casts. The containing bed is there- fore referred to that member, as is also the entire Cretaceous portion of the section, embracing 50 or 55 feet of strata. The beds in their present condition lack the calcareous character of the typical beds of the member, but the fossil-bearing bed was originally calcareous, the shells and other calcareous material having been subsequently replaced by silica.

Hazard, and the photographs were retouched by Miss Frances arrt.10 CRETACEOUS FAUNAS OF THE CAROLINAS—-STEPHENSON 5 Wieser, chief scientific illustrator of the Geological Survey, who also made the several drawings. Gi DESCRIPTION OF SPECIES CASSIDULUS KELLUMI, new species Plates 1, 2; plate 3, figs. 1, 2 Description —Test broadly ovate in basal outline, rather high and dome-shaped; base slightly concave, with two broadly expanding concave areas extending from the peristome to the ambitus, one on either side of the posterior center; these concave areas are separated from each other by a broad, low, rounded posterior ridge which ends at the ambitus in a slight protuberance or angulation below the periproct; a slight protuberance on the ambitus also marks the outer corners of each of the two concave areas at equal distances from the separating ridge and each protuberance is continued as a faint ridge up over the test; the protuberances and concave areas produce a slightly truncated effect on the ambitus at either side of the posterior center. The upper surface is not smoothly domed, for each am- bulacral area is distinctly raised between the pore bands, and each interambulacral area is divided into three flattened or slightly con- cave bands, widest at the ambitus, narrowing upward toward the apex, and the test is slightly humped above the periproct. Dimen- sions of the holotype: Length, 58 mm.; width, 53 mm., height, dl mm. The ambulacra are moderately broad in the petaloidal portions, become narrow at the lower ends of the petals, broaden out toward the ambitus, narrow down again on the base as they approach the peristome, near which they again broaden out sharply to form the fioscelles. In the petals the pores are small, and the pairs are con- nected by very narrow furrows, much narrower than the intervening ridges; the inner pore is slightly elongated, but in deeply weathered specimens is seen to be not quite so long as the outer one; the pairs of pores are very closely spaced and trend obliquely downward away from the center of the petals, and the petals are almost closed at their lower ends; below the petals very small pores can be dis- cerned on the ambulacral plates all the way to the floscelles. The floscelles broaden out sharply and are composed of long narrow more or less irregular plates each with a pore near its outer end; seven or eight pores on either side of each floscelle form an arch broken above by a group of six or seven pores on irregular plates, which form a small imperfect minor arch sunken considerably below the crest of the main arch. Pores occur on the inner ends of some of the plates of the floscelles, and form an irregular double line of five or six pores. 6 PROCEEDINGS OF THE NATIONAL MUSEUM VoL. 72 ~ The ambulacral areas between the pore bands are distinctly ele- vated. The ambulacral plates in the petals are long horizontally and very narrow, and consequently very numerous. ‘The interambulacral plates are much larger, the largest ones being three or four times. as long horizontally as they are wide. The whole upper surface is densely packed with tiny primary and secondary tubercles; even the ridges between the pore slits support each a row of tubercles; each primary is surrounded by a distinct areola and on some of the primaries a minute mamelon can be detected. The base is covered with similar larger and more widely spaced primary tubercles with distinct mamelons, some of which can be seen to be perforated, and each primary is surrounded by a relatively broad areola; the secondaries are tiny and relatively few. The apical system is situated 0.46 the length of the test from the anterior end; as seen in a slightly worn specimen, the madreporite is subcircular and relatively very large, the three other genital plates are small and perforated, and the ocular plates are minute, with no sign of perforations; as seen in a more deeply worn specimen, the madreporite is relatively smaller, the other genitals are larger, the oculars are larger and perforated. ‘The raised apical system on the specimen shown in Plate 3, Figures 1, 2, is apparently an abnormal feature, as none of the other specimens possess it. The significance of this peculiar feature is not known, but Austin H. Clark has called my attention to a similar raised apical system on one specimen of the Recent Stereocidaris leucacantha A. Agassiz and H. L. Clark. The peristome is situated centrally in a slight concavity of the base, is large, and includes five prominent oral lobes whose tips closely approach each other and are separated by deep, narrow ambulacral furrows. The outer surface of each oral lobe is covered with tubercles and is bordered by a slightly raised rim; the walls of the ambulacral furrows are densely packed with very small tubercles of regular size, arranged in rows parallel to the sloping outer surface of the lobe. ‘These features are beautifully preserved on the type, the peristome of which is nearly perfect in all its details. The periproct is high on the test, is small, and is situated in a deep, narrow sulcus which flares out and becomes shallow toward the ambitus. Remarks—Perhaps the most closely related American species is Cassidulus porrectus Clark,? from the Ripley formation, E'zogyra costata zone, in the vicinity of Eufaula, Ala.
