Description of a New Genus and Species of North American NOCTUINA,
BY AUG. R. GROTE.
Curator of Entomology. Buftalo Society Natural Sciences.
PHILOMMA. nov. gen.
Size moderate ; form slight ; wings broad ; anterior wings with the internal margin straight, external mai'gin moderately oblique and rounded, costal margin slightly rounded, 12-veined, veins 5 and 0 free, vein 4 equidistant from 3 and 5 at base, diseal cell open, subcostal cell small, elongate, its lower marginal vein indented midway between each extremity; posterior wings i^-veined, veins 1 and 2 free to base, veins 8 and 7 (costal and subcostal) diverging from a common stem at the extreme base ; antennse moderate, simple ; tongue short ; thorax mode- rately clothed with fine short hair ; abdomen moderately stout, slightly exceeding the posterior wings, smooth, not crested ; palpi slight, hardly exceeding the front; legs moderate, evenly clothed with short pubes- cence, hind tibia3 with four moderately stout spurs.
I erect this genus for a delicate Noctuid belonging to M. Boisduval's Ife.liofhidf€, the ornamentation of which is peculiar and different from anything I have yet met with in the Noctuina. The ordinary spots and lines are absent except the transverse posterior line which is indi- cated by the difference of coloring between the median and subtermi- nal spaces and by a series of white dots on the veins. At the outer extremity of the diseal space, at the base of vein 5, is a small neatly defined I'ounded ocellus with a whitish center, aunulated with reddish, and a second, larger, and with a blackish center, is situated on the median vein anterior to its furcation ; these ocelli at first sight seem to indicate a corresponding vein structure, which, on denuding the wing of scales, is seen not to be the case.
The pterogostic structure resembles that of Aiifhoecia {inarglnata) ; the subcostal cell is broader at the middle and vein 4 is not so near 8 at its base ; the tongue is shorter, wings relatively broader than in Anthuecia.
The eyes in the dried specimen are ornamented with petal-sliaped marks, diverging, like radii, from a common center.
1S(U.] 3
Philomma Henrietta, ikiv. sp. (Plate 2, fig. 1.)
Anterior wings broad ; ordinary spots and lines obsolete. Median and basal spaces bright lemon yellow, without markings except two ocellated spots : the smaller, situate at the outer extremity of the discal cell at the base of vein 5, with a whitish center and a reddish encir- cling line which is darker shaded internally : the larger, situate on the median vein anterior to the branches, with blackish center and similar encircling line. Transverse posterior line subobsolete, regularly undu- late, slightly arcuated superiorily, indicated by a series of white spots on the veins, subterminal and terminal spaces narrow, bright rose color ; subterminal and terminal lines entirely obsolete ; fringes rose color.
Costa rose color j internal margin from transverse posterior line to base narrowly bordered with the same shade.
Posterior wings silky, pale brownish, paler along the external mar- gin ; fringes pale, very slightly shaded with rose color.
Under surface of anterior wings silky, blackish on the disc, shaded with rose color in the terminal space and along costal and internal margins. Under surface of posterior wings silky, pale yellowish, shaded with rose color along costal margin and at external angle. Palpi, head, thorax and tegulje, rose color ; abdomen greyish ; legs ro.se color on their outer surface, tarsi greyish. Expanse f inch.
Hah. Eastern States. Coll. Ent. Soc. Philadelphia.
My specimens are apparently all 9 9 , and were taken by Mr. Rid- ings during the mouth of August at mid-day, on leaves of plants in the northern part of Massachusetts. The rose color of the anterior wings is brighter, but recalls the same shade in Alaria flortda.
I append a list of the described North American species of Noctuina included under the present sub-family, following almost entirely the arrano-ement of Mr. Walker. I am led to believe that the limit of the genus Hrliothis is at present too restricted, aud that the species included under Orla Cleyer. and perhaps other allied genera, will ulti- mately be found not improperly associated under the same generic name with annigara, though the coloration is widely different.

Notes on TENTHREDINID3;, with descriptions of new species,
In the Collection of the Entomological Societiy.
BY EDWARD NORTON.
Genus TEICHIOSOMA.
1. Trichiosoma triangulum. Kirby.
In place of the triangular black spot which ordinarily covers most of the tergum, a specimen from Colorado has most of the tergum yel- lowish rufous, with irregular black spots on the two basal segments above and beneath. Otherwise it agrees with specimens from Hud- son's Bay Territory and California.
Rocky Mountains, Col. Ter. (Coll. Ent. Soc. Philad.) One male.
Genus HYLOTOMA.
2. Hylotoma McLeayi. Leaeli.
Leach describes the wings as •• subfuscous, at the apex subhyaline." but the most common species in this country, which has come to be considered the typical species, has the wings smoky, at the apex clear, with a round fuscous spot beneath the stigma, which touches the first submarginal and does not extend beyond the black dot in the niiddle of the second. This is found from Maine to Illinois.
3. Hylotoma ceruleus. u. sp.
Blue-black, with violaeeou.- wings aufl a fuscous s))ot below tlie stigma. (Long 0..32. Br. wings 0.70 in.)
9 . Color violaceous, shining : antennse short, stout, black ; palpi white: legs tlie color of body, their knees and anterior tibife dark pieeous ; wings smoky violaceous, clearer toward tlie tips; the whole of marginal cell fuscous; a round darker spot below the stigma, covering most of the first and second submargina 1 cells: nervures black: lower middle cell of underwings not more than li.-ilf as long or large as the upper.
Pennsylvania. (Coll. P]nt. Soc. Philad.) One female.
1. Hylotoma clavicornis, Fab.
This has the wings hyaline, their basal half a little smoky; the fus- cous spot below the stigma semi-cylindrical, with the flattened side toward the tip of the wings.
Massachusetts. (Coll. Ent. Soc. Philad. j
r>. Hylotoma abdominalis, Leach.
This is larger than //. chiricorhlx. but is very much like it ; the ab- domen is of one color, with the apex beneath sometimes blue-black ;
6 [April
the wings have the fuscous ;<pot below the stigma round, with some- times a fainter lengthened spot beneath, and their base more or less smoky.
The male is undescribed. Its antenn;« are longer and are only tipped with yellowish. Its legs are black, with the anterior tibia3 pale before. The wings are clearer and the fuscous spot less distinct.
Massachusetts. ($1. SI.)
(i. Hylotoma scapularis, Klug. //. cdlcanea. Say. (Jrdinarily, the male and female are alike, having the head, breast, metathoras and abdomen blue-black ; the pro- and mesothorax, scutel and pleura rufous, the legs blue-black, tibia) and tarsi more or less whitish beneath ; wings violaceous.
Var. a. % ■ Only the prothorax rufjus; the mesothorax, scutel and pleura the color of body ; legs below the knees almost entirely white : apical third of wings hyaline.
Pennsylvania. (Coll. Eut. Soc. Philad.j
A pair was taken in coita^ of which the female resembles the usual ty|)e, and the male varies as above.
C4enus ATOMACERA. 7. Atomacera ruficoUis. n. sp.
Black, the pro- and mesothorax and scutel rufous. (Long 0.17. Br. wings 0.40 in.)
9. Shining black, short and stout; antenn;© thickly ciliate, 3rd joint not clavate but decreasing in size from before the middle, very slender at tij) ; the 4tli and otli joints of palpi flattened and enlarged, apical joint of equal length. but slender: basal third of antennas and face lieueath ferruginous, hairy: teg- ul8e. anterior angle, mesothorax and scutel rufous : legs black, their anterior tibite dull whitish, tibial spurs very short and sharp; wings ample, blackish fuscotis, clearer toward the ajDex, nervtires blackish, stigma large : four sub- marginal cells, the 1st small, its cross nervine clear and indistinct, 2nd cell of equal width throughout, 3rd wider at apex than long: lanceolate cell short, petiolate : uuderwings with two middle cells.
Pennsylvania. (Coll. Ent. Soc. Philad.) One female.
Not having seen either of Say's species, I cannot feel sure that it belongs to this genus. The form of the 3rd submarginal cell is (juite different. The abdomen is pointed like that of JVemafus, while that of Srhizorrruti is like Hi/lotoma.

••The labial palpi tour-jointed, the basal joint elongate, the second nearly twice as long, the third and fourth minute, the third inserted at tlie aj^ex of tlie second, the fourth at the apex of the third, the two latter elavate, truncate At their aj^ex. The maxillary palpi four-jointed, the basal joint stoutest, broad- est at the base, about the same length as the second and third joints, the apical joint minute. The superior wings with one marginal and two submarginal cells, the second submarginal cell receiving the two recurrent nervures.
•• In tlie female the head is usually very large, subquadrate, the ocelli placed forward on the vertex in a sliglit curve; the abdomen furnished with a dense l)ollen-brush beneath.
" Males usually reseuxbling the female, but more slender, having the antennae longer, and the apex of tlieir al)domen generally armed with spines or teeth." — Smith, Bees of Great Britain, p. 1.57.
The bees of this interesting genus are generally of a bluish or green- ish color, having a short, robust form, more or less pilo.se, the head large, especially in the females, and the abdomen mostly subglobose. A very interesting account of the economy of these bees is given by Mr. Smith (Ibid. pp. 158—162).
In this paper I have 33 North American species to record, all i)f which are known to me except two — 0. frigida Smith, and 0. hurco- lu's Say. In separating the closely allied species, I have relied much on the difference of sculpture and punctatiou, which seems to be very constant in the same species, although when more material has been accumulated, we may find intermediate grades of variation that will make varieties of some that are now considered distinct species.
1. 0. bucephala. n. sp.

The dark purple color and the narrow whitish fasciae of the abdo- men of this species, will readily distinguish it from all others known to me. The whitish apical fringe of the abdominal segments are very conspicuous when held in certain lights, and also on the apex of the abdomen where the segments are more retracted.
The specimens before me of this species were labelled 0. bucconis Say, but in that species the color is said to be "black," and the ven- tral scopa "fulvous"; but in the species before me the general color of the body is conspicuously dark purple, and the ventral scopa is black.

Hah. — Rocky Mountains, Colorado Territory. One specimen. (Coll. Ent. Soc. Philadelphia.)
This species probably belongs to the genus under which it is placed, as the maxillary palpi have but two joints, and the wings have the second recurrent nervure received a little beyond the apex of the second submarginal cell. The general appearance is similar to an Osmia, but the head is narrower than the thorax and the abdomen is without a ventral scopa.
Genus XYLOCOPA. Fabr. 3. Xylocopa californica, n. sp.
Female. — Head large, as wide as the thorax, black, slightly tinged with blue and green, especially on the cheeks, sparsely clothed with short black pubescence, that on the lower portion of the cheeks much longer; face flat, closely and conflueutly punctured, the punctures on the vertex stronger, those on the cheeks sparse ; on each side of the face a deeply impressed longitudinal line commencing at the insertion of each antenna and ending on the lateral margin of the clypeus; on the middle of the clypeus a short, smooth, slightly elevated, longitudi- nal line, anterior margin truncate, smooth and polished ; anterior mar- gin of the labrum smooth, polished, with a small, square, emarginate process in the middle ; mandibles smooth, polished, with a small patch of punctures near their base, the outer and inner margins channelled, the apex obtuse and slightly emarginate ; the extreme lower orbits of the eyes, at the base of the mandibles, flattened, smooth and polished. Thorax clothed with rather dense black pubescence, closely and deeply punctured, except the disk above which is smooth, polished and with- out pubescence; beneath bluish-green, above black and on each side of the disk between the wings, where the surface is punctured, it is iride- scent ; middle of the mesothorax in front with a finely impressed lon- gitudinal line which becomes obsolete before reaching the posterior margin ; scutellum closely punctured, golden-green. Legs bluish-green, clothed with black pubescence. Abdomen dark-green, with a blue and purple reflection, polished, sparsely punctured, the sides of the apical segments more closely and deeply punctured ; disk of the apical seg- ment with two oblique pubescent carina, meeting posteriorly and diverging anteriorly ; this segment, as well as the fifth, fringed with

Colored same as B. oagttns Smith, but is much smaller and more robust in proportion to the size. Mr. T. B. Ashtou collected a number of this species, all females, early iu the spring, in Northern New York, together with females of B. vagans, /ervidus, borealis, virffinicus, pen- sj/lvanicus. scparatus^ and tcrrlcola.
h. Bombus centralis, n. sp.
Female. — Head black, with a tuft of yellowish hairs above and be- low the antennfe and on the vertex. Thorax yellow above and on the sides, with a broad black band between the wings. Wings subhyaline, stained with fuscous, especially along the costa. Legs black, with black hairs ; tarsi rufous within. Abdomen with the two basal segments yellow, with a rather large black patch on the disk above ; the third and fourth segments pale orange-yellow; the apical segments black; beneath clothed with short yellowish pubescence. Length 8 lines.
Hah. — Fort Crook, California. One specimen. Mr. H. Ulke. (Coll. Ent. Soc. Philadelphia.)
Closely resembles B. Jiavifrons Cresson, but is rather more robust, and may be at once distinguished from that species by the black patch on the disk of the two basal segments of the abdomen above.

In mv list of the N. A. species of Bombixs (Pror. Ent. Soc. Philad.
42 [April
11, p. 93), I referred to this species, with some doubt, a single 9 speci- men from Canada ; since then I have received, through the kindness of Mr. WilUam Saunders and Mr. T. B. Ashton, a fine series ( 9 , $ and S ) of the true horealis of Kirby. The characters of this fine species are as fijllows : —
Female. — Head black, with the face and vertex clothed with pale yellowish pubescence, slightly tawny on the vertex. Thorax above densely clothed with bright tawny-yellow pubescence, with a broad black band between the wings ; beneath entirely black. Wings fuseo- hyaline. darkest along the apical margin. Legs black, tarsi pale with- out, rufous within. Abdomen above with the four basal seamen ts clothed with bright tawny-yellow pubescence, the two apical segments black; beneath black. Length 8 — 9 lines.
Worker. — Colored same as the female. Length 6 lines.
Male. — Like the female and worker, except that the antennae are as long as the thorax and setaceous, the sides of the thorax and the femora beneath are sometimes mixed with yellowish, the three apical segments of the abdomen above are more or less mixed with yellow and the last segment is tufted, the ventral segments are clothed with short pale yel- lowish pubescence. Length 7 — 8 lines.
Hah. — Canada (Saunders) and New York (Ashton). Coll. Ent. Soc. Philadelphia.
The males have much the appearance of some of the S varieties of Apatliu.-i elatua Fabr., but they do not belong to that genus.
The single 9 specimen which I supposed to be identical with this species, difiers from the 9 above described by having the abdomen above tawny-yellow, except the last segment which is black, and the ventral segments are clothed with short pale pubescence. It may be only a variety, and for the present it is probably best to consider it as such.
Genus APATHUS, Newm. 7. Apathus Ashtoni, n. sj).
Female. — Head entirely black. Thorax clothed above with pale yel- lowish, and beneath with black pubescence, on the disk above between the wings there is a mixture of black hairs and the scutellum is some- times altogether black. Wings fusco-hyaline, darker along the apical margin. Legs black, with black hairs, tarsi within rufous, the apical

joints exteriorly pale rufous. Abdomen black, smooth and shining, the posterior margin of the third segment above, broader laterally, the whole of the fourth and the extreme sides of the fifth segment densely clothed with yellowish pubescence, the remaining segments rather sparsely clothed with black pubescence ; apical segment smooth and shining, without pubescence ; in one specimen the basal segment above has a mixture of fuscous pubescence ; beneath black.

STATED MEETING, M a y 9 . President Bland in the Chair.
The Secretary read a letter from Mr. John Kirkpatriek of Cleveland.
Ohio, transmitting to the Society pupae of Eudryas uiiio in stems of
Hibiscus militarise which is abundant in wet swamps. Mr. K. says : —
■' The first time I found the pupse was last spring (1863) in pieces of stem washed ashore. Last winter I visited the localitj' on the ice and found nearly all the dead stems of the above jJlant burrowed by the larvre, and containing pupse. In the burrows of the Eudryas, a friend of mine found a few pupae of a dipterous insect and much resembling the pupae of the Tachinas that destroys the army worm. For many days last fall, there was a constant stream of but- terflies passing over this city : occasionally hundreds would be seen at once, at other times only a few. They were all of one species — Danais archippus. Its food-plant is abundant here. The larva of Sesia diffinis feeds on the leaves of the Snowberry (8ymphoricarpus racemosus) and also on those of the upright Honeysuckle {Lonicera tartarica) in gardens. Neither Dr. Harris or Dr. Clem- ens observed this. Three or four years ago I caught a specimen of Argynnis colvAnhina on the Cuyahoga flats, and within half a mile of this city. I have compared it with specimens from Florida, in the Cabinet of Prof. J. P. Kirt- land. and it in no wise diflTers from them. This is the only time, to my know- ledge, it has been seen so far north. Papilio cre.iphonten- was occasionally found here, but iiot since the cold winter of 1856-7.''

The foUowino- letter was read from Mr. James Aiitrus. dated West Farms, N. Y., April 15th, 1864:—
"A family of house-crickets have long been established in the house in which I live, but it is only of late that I have had my attention particularly directed to them. Harris says — " We have no house-crickets in America : our species inhabit gardens and fields, and enter our houses only by accident." Of course Dr. Harris must liave been entirely ignorant of the existence of a house species in this country similar to those in Europe. Now I have no means of knowing whether this opinion is universal, or whether the discovery has ever been made that we have house-crickets in this country ; but if such is the case. I think it will be found after an inspection of those I have lately captured in this house, to be an error. I have long been familiar to the creaking sound of these crickets, but thinking they had merely found their way there from the field, I never took any pains to find them out; but by mere accident one was caught a few days ago. and which, to my surprise and joy. proved to be an en- tirely distinct species from those inhabiting our gardens and fields, and having a close resemblance to, if not the same as, the European house-cricket of which I have got 2 poor specimens with which to compare them. They are light- brown with dark markings, not quite so large as the field-cricket (4c/iete abhre- viata Harris) and seems to be larger than its European representative. Like the latter its wings are very long, extending far beyond the wing covers. Per- haps this species is already known, but if not, it ought to be described, and for this purpose, if desired. I will gladly furnish specimens. Their haunts are very difficult to get at, and they are so shy and nimble that it is rather diflficult to get thera. I have only got so far 3 '^ and 1 9 •"
The Secretary also read the following extract from a letter from Mr. A. S. Packard, Jr., diited Brunswick. Maine, April 28, 1864 :—
•' I was overjoyed to-day to find both a 9 and "J, Stylops Childreni ! I took in my net an Andrena placida Smith, and just as it was nettled and I was about pinning it, I saw the % Stylops. On comparing it with Westwood's figure and details in Griffith's Cuvier, pi. 49, I have but little doubt that it is that species, for it will be seen in Westwood's Classif. that the insect was brought over to London in an Andrena collected in Xova Scotia. The Andrena placida was stylopized also, fortunately, for I found a single female in the abdomen — that is, what I call a female — for it may be remembered that Westwood and others call it a larva, wherein they were corrected by Siebold. Now I have little doubt but that the % Stylops was hatched from the body of some other Andrena. and flew upon the body of the Styloiiized specimen which I caught, to ' have a consultation ' with the 9 escoused within. For this purpose the % abdomen is very long and extensile, with two anal forceps capacious for seizing the female, and I have little doubt the anal tip is forced in to meet that of the 9 which is perhaps not so entirely immoveable but that it can be bent around and out- ward somewhat. This I can tell by dissection of the Andrena. In Westwood's figure the abdomen is represented as being very short, but it must have been drawn from a dried specimen when the region was withered and much short-
1S64.] 45
eued. It must be that the 9 9 '^""^ impregnated at this time, and that in the middle of June, as I have already observed, the viviporous young are hatched from the body of the parent. I do not see that the presence of this Stylops necessarily kills the bee or wasp, unless there are five or six individuals within the same bee-body."

Description of several new North American CTENOPHOR.ffi. BY BARON R. OSTEN SACKEN.
Five species were enumerated in my Catalogue of the descrHjed diptera of North America, under the head of Ctenophora. Subse- quent investigations have proved that two of them, C. fuUginosa Say, and C. ahdominalis Say, are true Tipulae. C. Parrii Kirby, seems also to be a Tlpida. The two remaining species G. dorsalis Walker, and C. succedKiix Walker, may perhaps be identified with two of the new species described below, although this identification, as will be shown, is by no means certain.
L Antennse of the male with four rows of branches, the tiro larger ones on file outside, the two smaller ones on the inside ; antennse of the female rather short, serrated ; male genitals clavate, but of moderate size ; female ovipositor short.

Head yellow, palpi yellowish, brownish towards the tip: front above the an- tennae yellow: a black, triangular spot occupies the remainder of the front and the vertex. Thorax more or less tinged with bright lemon-yellow on the ante- rior part of the prothorax above and on the pleurae: intermediate stripe brown- isli-bhick, triangular: lateral stripes brownish, very much abbreviated anteri- orly. Ilalteres yellowish-ferruginous with a more or less distinct trace of leinon-yellow on the knob. Feet ferruginous: coxse more or less tinged with lemon-yellow ; anterior half of the femora somewhat paler than the posterior one (especially in the male). Tarsi dark tawny, two last joints blackish : in the female, the basal joints of the tarsi are lighter ferruginous. Abdomen brownish-ferruginous, with a more or less distinct, narrow, black dorsal stripe. generally interrupted at the incisures of the segments; posterior corners of the intermediate segments, on the back, as well as on the venter, more or less tinged with lemon-yellow. Wings subhyaline, a yellowish tinge along the anterior margin, which reaches as far as the stigma; a similar tinge along the fifth longitudinal vein; stigu^a yolk yellow; a large brown cloud behind it, which on one side has a definite limit, formed by the cross-veins between the stigma and the discal cell ; on the other side (towards the apex) there is no such limit, and the brown fades away gradually; this cloud does not touch the costal margin, so that there is a small hyaline space left between it and the stigma; posteriorly, the cloud covers the apical half of the discal cell and does not reach beyond the hind margin of this cell.
Male. Antennae rather long (reaching somewhat beyond the root of the wing), with four rows of branches ; the inner ones about half so long as the outer ones; the three basal (branchless) joints and the flagellum. except its extreme tip. are yellowish : the branches are brownish. The male genitals are clavate. but the club is smaller than that of the species of the following section ; their color is brownish-ferruginous, blackish above.
Female. Antennae hardly reaching the root of the wings, serrated, ferrugi- nous-yellowish ; upper valves of the ovipositor very short and, beyond their broad basal portion, abruptly narrowed and almost linear: their tip is rounded. Hab. Illinois (Mr. Walsh.)
Observation. — I have seen in Dr. Harris's Collection in Boston, two female specimens of a Ctenophora, which, judging by the structure of their antennge. seem to beldng to this .section. I reproduce here the short description made by me, at the time when I saw them.
C. apicata n. sp. 9 •
Whole body yellowish-brown, shining; some darker spots on the vertex and thorax ; abdomen also darker, with the hind margin of one or two intermediate segments yellowish.

Antennse of the female longer than head and thorax together, basal joints black, Hagellum more or less ferruginous, extreme tips of the joints black, terminal joints more or less infuseated, the first joint of the fiagellum is but little shorter than the first antennal joint, the following joints of the flagellum gradually decrease in length; the four or five penultimate joints are subellip- tical and of about equal length. The whole thorax black, shining; a whitish spot on the posterior end of the membrane between the collare and the root of the wings. Halteres with a blackish stem and a dingy whitish knob, or alto- gether blackish ; abdomen of the male altogether black with large, club-shaped genitals ; abdomen of the female black, the two basal segments ferruginous : the latter half of the abdomen is tapering and ends in a long, sword-shaped ovipositor. Feet of the male black, the foremost pair rather brownish: the fore- most tarsi livid-brownish from the tiji of the first to the base of the fourth joint : feet of the/effia/e ferruginous, coxse and trochanters black: tarsi brownish, ex- cept the first and the root of the second joint, which are ferruginous. Wings uniformly brownish ferruginous, with a dark brown stigma. The second and third longitudinal veins are nearly parallel, only very slightly diverging to- wards their tip.

Observation. — One of the male specimens seen by me in the Cabi- net of the Entomological Society in Philadelphia, has the basal two- thirds of the wings almost hyaline, and the apical third is less brown- ish than in the other specimens. There is also a small hyaline spot beyond the stigma. It is evidently only a variety.

The coloring of the body is usually black, mixed with ferruginous, so that the black prevails on the thorax, the ferruginous on the abdomen, which, in most specimens, has a black, more or less extended, dorsal stripe. Among five males one had a black abdomen, the hind margins of the segments tinged with yellowish and some ferruginous spots on the sides of the two first, on the two last segments and on the club. When the tliorax is black, there is a percep- tible dull tawny sj)ot above the middle eoxte and a dull reddish spot on each side of the metathorax. In some specimens, the reddish color prevails on the thorax so as to leave only three broad, black, shining stripes on its back. The only female which I have seen, had a ferruginous thorax, with the exception of dark spots on the pleurse.
Anteunse of the male black at the base, flagellum grayish-brown in some spe- cimens, yellowish-white in others, with three rows of branches, the interme- diate one being the shortest. Antennte of the female longer than head and thorax together; three first joints brownish, the following ferruginous, more or less tipped with brown ; the proportion between the length of the joints is the same as in the female of C. fumipennis. On the thorax, the membrane be- tween the root of the wing and the collare is bright yellow : the pleuraj have a slight grayish down. Halteres yellowish, their stem sometimes infuseated. Male genitals large, clavate: female ovipositor long, sword-shaped. Femora ferruginous, dark brown at the tip : fore tibiae dark tawny, still darker towards the tip: middle and hind tibiae ferruginous-tawny, darker at the basis and grad- ually infuseated towards the tip. Tarsi dark brown, the tip of the first joint and the three following joints of the foremost ones are i)ale grayish brown. (The only female specimen liad altogether ferruginous feet, except the tarsi, which were brown, from the tip of the first joint.) Wings with a somewhat topazine yellowish tinge ; veins brown ; the interval between the costa and the first longitudinal vein more saturate yellow; stigma dark brown: its anterior por- tion sometimes paler; one of the males had a rather indistinct small grayish cloud, occupying the latter two-thirds of the discal cell and somewhat encroach- ing upon its surroundings; the extreme apex of the wing is also slightly mar- gined with gray : the second and third longitudinal veins are nearly parallel and the distance between their tips is somewhat shorter than the distance be- tween the tips of the third and of the following veins. Hah. Virginia (Dr. Wilson.)

Head lilack. mouth browiiisli. palpi hrownish-yellow. their tip hhick ; an- tenuw pale ferruginous; branches brownish gray, in three rows, the interme- diate row being the shortest. Thorax ferruginous, shining above ; hardly any vestiges of stripes are perceptible : the membrane between the root of the wings and the coUare dingy-yellow. Ilalteres yellow. Feet pale ferruginous: tips of the femora slightly brownish ; the extreme tips of the tibipe. including the spurs, brown: tarsi pale brownish, the extreme tips of the ?,d and 4th joints are l)rown : last joint dark brown. (The foremost feet are wanting in my only specimen.) Abdomen ferruginous, a Idack dorsal stripe of rather indefinite outline, begins at the second segment and ends at the base of the large, club- shaped male genitals, which are entirely ferruginous ; this stripe occuj)ies how- ever only the middle of the dorsal segments, the sides of which are ferrugi- nous. Wings altogether hyaline, even the space between the costa and the first longitudinal veins is without any tinge; veins yellow at the basis of the wings, black on the remainder of their surface; stigma brown : the 2d and 3d veins are distinctly diverging towards their tips, so that the distance between these tips is somewhat larger than that between the tip of the .Sd longitudinal and of the following vein.
Hah. Massachusetts (Sanborn).
Obsi' rent ion I. — I possess an imperfect specimen of a female, which may belong to this species. Although the body is differently colored, the hyaline wings, yellowish at the basis, and the direction of the 2d and od longitudinal veins aiford strong points of analogy. I incline to believe that G. front<il!>^. like (\ fopazi'na, varies in its coloring from black to ferruginous. I let the description of this female follow :
Head and thorax black, shining; palpi tawny at the base, the last joints black: antennae brown: first joint black above: the third joint (first joint of the flagellum) is about half the length of the first, incrassated towards the tip on its upper side and therefore, clavate : fourth joint linear, somewhat longer than the third: the fifth joint also linear, about | of the fourth: the 6th still shorter; the 7th and the following are subelliptical. the three penultimate joints subglobular. The membrane between the root of the wings and the col- lare is yellow. Halteres yellow. Fore coxae black, clothed with pale hairs, their extreme tip and the trochanters ferruginous ; middle and hind coxae pale ferruginous, black at the extreme basis ; femora ferruginous, the extreme tip brownish above: tibife dark tawny, paler on the inside; foremost tarsi dark brown; the first joint and the extreme basis of the second joint pale brownish. (The other tarsi, as well as the abdomen, are wanting.) Wings as in the male.
Bab. Ohio (Capt. Holden.)
Ohxervation TI. — It is not impossible that this is 6'. Kurrfdrns Walk., although the description of this species in the Diptera tSaaia/n-.'o'aiia is too unmeaning to admit of any conclusion, the more so. as Walker describes only the female.

Notes on some of the DIUENAL LEPIDOPTERA of the State of New York, with descriptions of their Larvae and Chrysalides.
By J. A. LINTXER. Utic.\. X. Y.
The following pages are compiled from a series of Notes, extending over a period of seven yeai's, during which time the writer was engaged in making a collection of the Insects of Schoharie, in Eastern New York, where he was then residing. Believing thorough explorations of limited localities to be of greater value to science, than the simple bringing together through exchange, of large collections, most of the work done, was without the knowledge of what had been achieved by others, and what additions were still needed, toward the completion of our Insect biographies. Through this neglect, now much regretted. many rare opportunities were lost, of adding materially, by additional observations and notes, to the number and value of the few new facts now presented.
The collection above referred to, numbers over two thousand species, of which about one-half are of the order of Lepidoptera. The Notes. with few exceptions, are of the Lepidoptera, and embrace descriptions more or less full, of one hundred larvae.
Papilio turnus, Linn.
The earliest appearance of this butterfly, which I have recorded, is the loth May. In a warm room I have had it emerge as early as December 0th. It is usually not very abundant. In 1856, not one came under my observation, but the year following it was so plentiful that toward the last of June it could occasionally be seen in companies of ten or twelve, settled upon damp patches of earth, after the manner of C. philodice. In 1858 it was as abundant as phUodice — our most common species. The black variety, glaucm, does not occur here. I have very rarely captured the female, and in those which I have bred, the males have largely outnumbered the other sex.
The larva has been taken the middle of August on the Hop, resting on a slight web, spun by it on the_ upper surface of the leaf. An ex- cellent description of it is given by Benj. D. Walsh, in Vol. I. p. o52 of these Proceedings.

The chri/mlis is 1.25 in. long, yellowisli, marked with brown on the wing-cases and most of the tubercles, and with a stigmatal brown line : head-case short, bifid, beaks diverging, corrugated, reflected exter- nally, with two intermediate minute tooth-like projections; dorsal region to the ninth segment, ranging with the thoracic ; thoracic projection slightly elevated, right-angled, with two small brown tubercles ante- rior to it ; a single small humeral projection ; margins of wing cases moderately angular; segments from the seventh to the twelfth inclusive, with two dorsal rows of small warty tubercles, two subdorsal rows of smaller, and a minute black point beneath each stigma, — the three terminal segments, carinated laterally beneath, and not ending in a spine.
Papilio asterias, Fab.
First appearance of bntfrrjl//. May 6th ; within doors, in a warm room, December 13th. The middle of June, it may be seen depositing its eggs, singly, upon the leaves of the parsnip, caraway and other umbelliferous plants.
The eggs are of a delicate light yellow, smooth and round, with the exception of being slightly flattened where they are attached to the leaf.
The mature larva is well known. The young larva is nearly black, and very unlike its appearance after its last molting, at which time it assumes its green color.
Chri/sah's 1 in. to 1.10 in. long; head case long, with beaks nearly parallel — otherwise as in turnus ; thoracic projection brown, moderately elevated, descending perpendicularly in front; middle dorsal region, depressed, — the ventral region opposite, correspondingly convex ; dor- sal and subdorsal tubercles in number and arrangement, as in furnus. but larger, approaching to spines ; wing cases projecting at their pos- terior angle ; terminal segments beneath, as in turnus. (Described from dead chrysalides, and the coloration consequently omitted, as in several of the following species.)
Papilio troilus, Linn.
This is one of our most rare diurnals. and I am only acquainted with its imago. I have taken it twice, the middle of June, resting on damp ground ; others have been reported to me, in a neighboring locaHty, where its food plant. La urns Sassa/rax. is found.

PiERis OLERAOEA, Harris.
This butterfly, until recently, has been extremely rare in this place. Previous to 1857, T had taken it but once during the three preceding: years. At present, in numbers, it ranks second to C. philodicc. It is usually seen flitting about gardens, and in the streets, alighting occa- sionally upon damp spots of earth. It commences its daily flight at an earlier hour than any other species — often before seven o'clock — and is seen abroad until quite late in the afternoon.
There are three broods of this butterfly during the year. Of the first brood, I have taken individuals as early as the 18th of April. About the 10th of May they are abundant; a month later none are t<> be seen.
The second brood appears about the 1st of July, varying from this period, by a week earlier or later, as the season may influence their development.
The middle of August, a third brood makes its appearance. During the last week of August and the first week of September, they are very numerous, more so than at any other time of the year. At any mo- ment during the day one or more individuals may be seen on the wing. My notes show, that for two years, this brood consisted only of those which had the posterior wings simply tinged with yellow, without the conspicuous black veins. Is this uniformly the case ? So far as I am able to recall, both those which I have bred and captured of the first brood, have had the black veined yellow posterior wings. It will be interesting to determine by further observations, whether these diff^er- ences in the successive broods really exist.
About the 10th of October, the last of the brood are seen flitting about, with denuded and broken wings. By this time nearly all the larvae have matured, and their chrysalides may be found suspended beneath boards, or under shelter of the grasses growing beside garden fences in the immediate vicinity of oleraceous crops.
From the marked variations in color, presented by this species, — the inferior surface of the posterior wings in some, having but the slightest tinge of yellow, and in others, being of an orange yellow, with con- spicuous black bordered veins, — authors have been led to separate it into distinct species, or at least into permanent varieties. Although varying so much in appearance, there can be but little doul)t that they
1864.] 53
constitute but a single species. Collections have been made, in which the extremes are connected by every gradation of shade. But it is probable that any number of individuals, collected from one locality, at one particular time, will present a very limited range of variation. In the earlier years of its appearance in this place, those taken, with very few exceptions, were nearly immaculate ; none were found having the black veined yellow posterior wings, which during the last few years have been so plentiful.
I had hoped to institute a series of experiments and observations, on the variations which this species offers, with a view of determining as far as practicable, the following points, some of which had been sug- gested for my study, by correspondents :
a. The range of variation existing in the brood of a single 9 ■
b. The modification of variation, from the union of % and 9 "' *h® same
style of variation.
c. Ditto of different styles of variation.
d. Ditto of the extremes of variation.
e. Variation as modified, by the food-plant.
/. Ditto by the impeded development of the larva by cold.
9. Ditto by the impeded development of the chrysalis.
My attempts were as follows. I gave a % and $ which had emerged from chrysalis the same day, the freedom of a large, well lighted apart- ment, in which had been placed sugar and water for their food, and thrifty potted plants of horse-radish, cabbage, &c., for the $ to deposit her eggs upon. They were found dead after the lapse of a few days ; no eggs had been placed on the plants, and they probably had not mated.
I took pairs in coitu, and treated them as above, with the same result.
I captured females while depositing their eggs, and furnished them with plants as above, but no eggs were found upon them.
I inclosed in boxes, ovipositing females, with distended bodies ; re- sult as before.
It will be seen from the above, that all my efforts to pair the species, or induce it to deposit eggs under the slightest restraint, were in vain. I trust that others who feel an interest in the subject of the variation of our diurnals, may be induced to prosecute its study, experimentally, and that some method may be found of overcoming the difficulties
54 [May
which have presented themselves. I would be pleased to have com- municated to me any instance of the successful pairing of any of our butterflies.
Although so abundant at Schoharie, oleracea is not generally dis- tributed over the State. In leaving the valley, it diminishes in fre- quency as we ascend the surrounding hills. At Utica not one indi- vidual came under my observation during last year, while at Oswego. in the month of August. I found it very numerous.
The larva is .9 in. in length; tapering toward the extremities from the 6th and 7th segments ; head small, rounded, flattened anteriorly, of the diameter of the 1st segment ; segments with six transverse wrinkles; incisures rather deep. Color of the head and body, apple- green ; a lighter green stigmatal stripe, becoming whitish just before the change to chrysalis ; an indistinct vascular line ; body and head covei'ed with numerous short hairs, giving it a downy appearance. — those beneath, white — above the stigmatal line, black mingled with the white, arising from minute black papillae; stigmata broadly oval.
Ohrysalis, attached by its tail, and suspended by a girt about its middle; quite angular; head with a single point; thoracic projection, prominent, compressed laterally, apex rounded ; the two lateral projec- tions, margining the wing-cases, shai'p ; abdomen, slender, pointed, rounded beneath, with dorsal and lateral carinations. Color white ; wing-cases, with brown linings, a brown irregular spot near the tip. another near the base, and black points on the nervures and on the margin intermediately : a black spot in front of each lateral projection ; a short black line on the thoracic projection anteriorly and posteriorly ; the segments superiorly, each with a brown cloud above their lateral carination, and regularly dotted with black, as follows : four dots (di- vided by the dorsal carination) posteriorly, forming a parallelogram — four in a transverse line, nearer the anterior portion, and two still nearer together, farther removed from the dorsal carination, — the ten dots arranged in a W nearly.
COLIAS PHILODICK, Grodt.
I have seen this butterfly abroad as early as April oOth, and as late in the year as November 4th. As with ohracea^ there are, in all pro- bability, three broods each year, for after its first coming it continues
1864.] 55
coQstantly with us, until its final disappearance. It is only in the Fall that it can be seen collected on damp earth by the road-side, in com- panies of hundreds, when as many as twenty can frequently be taken at one sweep of the net, and thousands driven up in a few minutes walk.
The white variety of the 9 is not very rare in this locality, although recorded as rare by authors, for a year has seldom passed without giv- ing me one or more. In 1858 — a year remarkably prolific in insect life — I took six in a single field, in less than an hour's time. I have in my collection, one, in which the black border of the primaries is without the spots which characterise the ? , — and one in which the secondaries have on their inferior surface, but a single discoidal sil- vered spot.
Extremely abundant as is this species, I am unacquainted with its larva, but it could no doubt be readily obtained from clover fields, by the aid of a sweeping net.
Grapta comma, Harris. The larva^ a short time before its final niotling, is whitish, with pale green or blue markings. Subsequent to its molting, the three poste- rior wrinkles of each segment, the lateral flexures, the abdominal spines (except their tips, which are black) and a spot at their base, gradually change to a cream-color, as the larva approaches maturity. The six posterior segments have each a small orange spot above the stigma, — those of the 6th and 11th segments, sometimes quite minute. The dorsal markings in blue or bluish-green are as follows : on the vascular line, a .short line extending backwards from the front of each segment, half- way to the dorsal spine ; on either side, a curved line, commencing anteriorly near the front of the segment, in range with the sub-dorsal .spines, passing with a double flexure, obliquely toward the rear of the dorsal spine, just behind which the two lines are united by a short transverse line ; within these lines, midway between them and the vascular line, are two short dashes on the anterior of the segment, directed obliquely toward the dorsal spine. Head, flesh-color, thickly studded with white spines, the longest of which are black tipped, and terminate in a bristle; the two tubercles, of the color of the head. Stigmata, broadly oval, black, shining under a lens. Legs, bright red; ju'o-legs flesh-color.
56 [May
The larva suspends itself by its terminal legs, and assumes its chry- salis state twenty-four hours thereafter. The butterfly emerges after twelve days.
The chrysalis is fi-om .75 in. to .95 in. long, marked with six golden dorsal spots at the bases of the anterior spines. — reticulated with grey and white, and brown striped below the stigmata; head-case, with tw<» lateral projections, short, conical, quite acute ; a prominent thoracic spinous projection, compressed laterally, beneath which, on each side is a tubercle ; two humeral projections, the anterior one, subconical, — the posterior, elongated ; inferior wing-cases, with a prominence near the hind margin, on the sixth segment, parallel with the posterior humeral projection — the wing-case intermediately, deeply depressed ; two dorsal rows of spines, from the third to the tenth segments inclu- sive, short, except those of the seventh segment, which are thrice the size of the others; terminal spine, long, flat, slightly curved.
The above larval description is from ten individuals, taken on the Hop, between the 10th and last of August. At the same time, one was taken, difiering so much in coloration, as to deserve a separate de- scription. Larva, light yellow ; above the stigmata, a black stripe, iu which is the row of spines with the orange spots at their base — the stripe in its breadth reaching nearly up to the subdorsal row of spines, and sending off", on each segment, the double curved line above de- scribed ; the short vascular line is also black ; the lateral row of oi'ange spots has one spot on the 5th segment, making their number seven, — those from the 6th to the 11th inclusive, are double, the additional spot being behind the spine, lower on the body than the other, and of smaller size. Head, shining black, with stiff" hairs and two branching spines, whitish. Body beneath, blackish. Spines, except of the substig- matal row. cream-color, with black tipped whitish branches ; trunk of the two lateral spines of the 2nd segment, black. On the three ante- rior segments, a whitish median line. Stigmata black. Legs red.
The butterfly obtained from the above larva does not diiFer materi- ally from other specimens of comma in my possession. These are the principal variations noticed : the large black spot resting on the ante- rior margin of each wing, is larger ; the two black spots situated be- tween the nervules of the sub-mediaa of the primaries, are smaller —
1S(U.] 57
the brown spot at their posterior angle is more distinct ; the six orange marginal spots of the secondaries, are brighter.
I deem it probable that we still have at least two species confounded in comma, — the determination of which will require close observation, and such particular larval descriptions as I have endeavored to give above.
The female has the wings less emarginated than the male. With the two side by side, a casual glance at the broad and short tail of the secondaries of the former, and the longer and more slender tail of the latter, will serve to designate the sexes. This difference is observable, though to a less extent, iu the other species of this genus. Another obvious sexual characteristic of Grrapta, is, the long hairs which clothe the anterior pair of legs of the male.
I have captured this butttn-Jiy &n.v\\ev than any other species, — flitting about in the warm sunlight of a spring-like day, on the 2nd of March. Although but slightly worn, it had undoubtedly been drawn out from its winter quarters.
The first brood makes its appearance in June. Its larva will proba- bly be found on the Elm, during the preceding month. Of the second brood, from the Hop, I have had them from chrysalis, from the 25th of August to the 5th of September.
GrRAPTA PAUNUS, Edwards.
This species is of much more rare occurrence in this locality than the preceding Among the Adirondack Mountains of this State, near Raquette Lake, in the mouth of August, I once met with a large gath- ering of them, upon a small spot of moist earth. Usually extremely shy as are all the Grraptas, my approach startled only a few of their number, which, after a short circuit, returned to their repast. I expe- rienced not the least difficulty in capturing twenty or more by hand, although another collector had preceded me — a large toad {Bu/o ame- ricaauii) — whom I found holding a central position in the group, and earnestly engaged in lapping up with his broad tongue, one after an- other of the company, with the greatest dexterity, seldom missing an attempt. After watching for some minutes the novel performance, I left him still gorging himself upon what I should judge to be unusual Batrachian diet.
58 [May
GrRAPTA PROGNE, Fab.
Larva, reddish grey ; spines white, with branches, some of which are bhick tipped ; tubercles from which the spines proceed, Hght red ; on each .segment two or three bhick bands posteriorly, and four short black dorsal lines, extending obliquely from its anterior edge, across one-third of its extent — -the two inner ones directed toward the cross- ing of the vascular line by the incisure — and the two outer ones toward a point on the following segment. Prologs, black exteriorly. Head small, strongly spiued. Length 1.25 inches.
While feeding, the larva detaches its terminal legs from the leaf, and curves upward its last two segments. T have taken it on the wild Grooseberry (^Rihes rotund ifuliiim) and on the Currant (^Rlbcs rubrum. ) In chrysalis, June 13th — 20th; emerges from chrysalis after twelve or thirteen days.
Chrysalis, .85 in. long; head-case prolonged in two parallel obliquely truncated horns, foi'ming a full U — their tips maculated with brown ; thoracic projection, not prominent; dorsum, slightly depressed, and its spines almost obsolete; humeral projections as in comma; wing-ca.ses. with a blunt projection near their posterior margin, and deeply exca- vated centrally; terminal spine, long, rounded, moderately curved.
The hutterjli/ probably hybernates. I have taken worn and faded ones, early in May, which had doubtless survived the winter. A few may be disclosed from chrysalis in the spring. Dr. Fitch gives July as the time of its appearance, and limits it to a single brood ; he records as worthy of note, that Dr. Harris had obtained it as late as the 18th of i^ugust. I have captured it fresh and just from chrysalis, the 7th of September — clearly establishing the fact which would naturally be expected from its close relationship to comma, of two annual broods. Toward the last of September and early in October, it may frequently be seen, regaling itself upon the juices of fallen pears and other fruit, in company with interrogationis.
Grapta j. album, Grodt.
Larva, two inches long, light green ; head with black markings on the sides — thickly set with setae and with short spines, of which the lateral ones are each tipped with a long seta — and armed with two shining black, thick spines, verticillated near the tip ; the dorsal and
1864.] 59
subdorsal rows of spines, shining black, except at base, which is rufous, with long branches — those of the anterior segments more numerously branched than the others, and having each point tipped with a seta ; the super- and sub-stigmatal rows, rufous, tipped with black.
Chrt/salis, one inch long — of a beautiful green, delicately reticulated under a lens — with six golden dorsal spots ; head-case, with conical beaks, less projecting and acute than in comma ; thoracic projection elevated in a compressed, slightly recurved beak, similar to comma, and tipped with black anteriorly ; dorsal spines, prominent — the superior one, about double the size of the others ; wing cases, moderately de- pressed— the humeral projections prominent — that near hind margins on sixth segment, moderate ; stigmata brown, with a brown spot beneath, centrally on the segment ; terminal spine broad, flat, deeply excavated beneath, and bordered with brown.
I have taken the larva but once. When captured, it was fully ma- tured, and crawling rapidly over the ground of a dense grove of varied timber, and I am therefore unable to give its food-plant. It changed to a chrysalis the 27th of June, and emerged after thirteen days.
The spinous head of the larva justifies its removal to the genus where I now place it, and where the silver character of the posterior wings naturally locates it. Its marginal series of crescents of green scales beneath (connected here in a band), the inner row of minute black dots, and the dentated markings of the basal region — are well known characteristics of the Glraptas; while the contracted silver marking, re- duced frequently to a mere dash, the wings less emarginate, and palpi more hairy, — show it to be the nearest allied of its genus, to Vanessa.
The hufterjii/ is quite rare. It hybernates, and is occasionally found, in the winter season, within old buildings, where it had taken shelter. The first warm days of March draw it from its retreat. In September a second brood appears, a portion of which pass the winter in chrysalis.
Vanessa antiopa, Linn. Larva^ two inches long ; velvety black, with whitish dots in trans- verse bands, from which proceed short whitish hairs ; vascular line, black, interrupted by eight or nine red spots, usually of a triangular form, having a spine at the apex, and one (subdorsal) in each side. Head, somewhat cordate, black, with a few small shining black tuber- cles, and whitish hairs. Abdominal spines, long, black, with a few
60 [May
black brunches aud whitish setae, and arranged as follows : none on the first segment ; on the second aud third segments, four each — the subdorsal ones exceeding all the others in length ; on the fourth seg- ment, six spines; on the remaining segments, seven each ; those of the substigmatal row have, in some instances, a dull red spot at their base above : the spines are not in a transverse line — the dorsal one occupy- ing the anterior of the segment, the substigmatal one the posterior, and the subdorsal and superstigmatal ones in range intermediately. This arrangement of spines is uniform in all the Vanessas. Legs, black ; prolegs, fulvous ; stigmata barely discoverable even under a lens, ex- cept when bordered, as sometimes, with whitish.
Ohysalis, 1 in. in length ; beaks of head-case, short and conical ; thoracic projection of medium height, nearly ranging anteriorly with the frontal beaks ; dorsal spines, long, quite acute, and excepting the last, nearly equal; anterior humeral projection, elevated, acute; wing cases, slightly depressed, and with a very moderate projection on the inferiors; terminal spine, short, flattened and quite broad.
Thebutfe7-Ji^ frequently hybernates, and has been seen abroad the 23d of March. It has three annual broods. The Jirst, from the chrysalides of the Fall brood, appears in May. The second brood is seen the lat- ter part of July. A colony of larvae, numbering about thirty, which I took on a small twig of Willow, early in July, after undergoing their last molting, were found on the morning of the 14th, to have sus- pended themselves during the night, preparatory to their change ; at the close of the day they had all assumed the chrysalis state. In eight days thereafter the butterflies emerged. Of the tkh-d brood, I have obtained chrysalides the middle of September, and the butterfly the 1st of October, after sixteen days — a longer time being required for the change, at this period of the year. A portion only of the chrysalides of this brood — those which were the first to reach that stage, or such as may have had positions more favorable for their development. — disclose their butterflies at this unfriendly season, when the cold autum- nal winds so soon compel them to shelter themselves in winter retreats.
An interesting peculiarity of this species — not observed by me in any other diurnal, and not to the same extent among the nocturnals where it is of frequent occurrence — is its habit of counterfeiting death. When newly emerged, within the breeding cage, it may be taken be-
1864.]
61
tween the fingers, without the slightest show of resistance ; at the first touch it fields up its legs and becomes seemingly inanimate. Released from the hand, it drops upon its side, and will even allow itself to be tossed from side to side without attempting flight. If left undisturbed for a short time, it slowly raises itself, and simply resumes its upright position.
This species varies much in size. I have it from two inches, to three and a half inches spread of wings — the former doubtless dwarfed from insufficient food.
Vanessa Milberti, Grodt.
Larva, length 1.10 in. ; anterior segments quite tapering; head small, with short hairs proceeding from minute whitish granulations ; body black, with granulations like those of the head, and with rufous dots sometimes coalescent, as on the back, where they margin a black vascular line, and anterior to each subdorsal spine, where they form a curved spot ; between the stigmata, a connected series of rufous cres- cents— each crescent convex above, extending from the lower portion of one stigma to the upper part of the following ; below the stigmata, a rufous stripe; ventral region, yellowish; legs, black; prolegs, rufous, anterior to each pair of which is a quadrangular brown spot ; spines clothed with delicate setfe, — the dorsal, subdorsal and superstigmatal rows, black, and the substigmatal, rufous. (The color of the crescents and dots is taken from an alcoholic specimen.)
Chri/saJ!.^, .8 in. in length, slightly angular: frontal beaks, short, conical ; thoracic projection forming nearly a right angle; dorsal spines, but little elevated — the superior one exceeding very little the others in size ; wing-cases, as in antiopa ; terminal spine, short, flattened, curved.
I have no knowledge of more than two annual broods of this butter- fly. It makes its appearance very early in the spring. I have taken the sexes, somewhat worn. In coHu, on the loth of March, — and on April 7th those which, without doubt, had been newly disclosed from chrysalis. A second brood appears about the middle of August, after having passed ten days in chrysalis. The larva is usually very abun- dant on the common Nettle ( Urtica dioica), growing by the roadside, — a very large number frequently clustering on a single plant. Although
&2 [May
so numerous, comparatively few pass beyond the larval state, the larger proportion falling victims to the parasite peculiar to it. Of twenty-five larvae, which I placed in my breeding cage, only five became chrysal- ides. From the body of each of the others when full grown, a number <jf grub.s emerged, and spun themselves up in small white cocoons, placed with perfect regularity side by side, forming a compact bundle, usually round in form, made up of from twenty to sixty cocoons — the whole en- veloped in a cotton-like substance. The cocoons are in every instance spun underneath the larva, to which they are attached by the sides of the lower layer, instead of by their base, as they commonly are ; as the mass increases, the body of the larva above it, is raised up from the leaf or stem on which it rested, embracing the bundle in its curve.
The larva presents us with an instance of great tenacity of life. Although every portion of its body had been honeycombed by the escape of the large number of parasites which it inclosed — sufficient, one would suppose, to produce speedy death — I have known its life to be prolonged for a period of seven days thereafter.
LiMENiTis ARTHEMis, Drury.
Larva, whitish, with small blue dots ; protuberances, terminal seg- ments and under side, olive green. Head, cordate, tuberculated and spined. Body, on the second segment, with two branching spines; on the third and fifth, each, two protuberances; on the eighth, two tubercles with elevated radii; on the ninth, two similar, but larger; on the eleventh, four spinous tubercles. Feeds probably on the Balsam Poplar (Poptdus balsami/era^, beneath which the larva was found, fully grown.
Chrysalis. 1.10 in. long; whitish, with margin of wing-cases and dorsal projection greenish — the latter silvery on its sides. Head-ca.se, square, with two short, blunt, diverging horns ; thoracic carination rounded, slightly elevated above the following segment; dorsal projec- tion, compressed laterally, quite prominent, forming nearly three-fourths of a broad oval ; margins of wing-cases quite angular ; central segments nearly cylindrical — terminal ones contracted abruptly; terminal spine, short and broad.
As it hangs suspended, it frequently turns from side to side, and very seldom rests perpendicularly. It becomes a chrysalis after the larva
1864.] 63
has been suspended thirty-six hours, and emerges nine days there- after.
I have taken the hutterfl// the last of June. It is usually quite rare, but on one occasion I met with a number of them, in a sheltered road- way in a wood, on elevated ground, sporting in the bright sunlight, with short and rapid flights. When it alights on a tree, it seldom re- mains stationary, but continues walking over the leaves, opening and folding its wings.
LiMENITIS DISIPPUS, Godt.
The larva has a marked I'esemblance to that of arthemis, and cannot readily be distinguished from it, unless by actual comparison. The green upon it varies from a pea-green to a darker shade, but is never so dark as in (irfhemis.
I have found the larva on the Gray Willow {Salix grisea^) in July. Several willows which I examined during a walk, on the 28th July, gave me each one larva or more, in different stages of maturity, from the second molting, to full grown. Their position was at once revealed by the twig upon which they had fed — usually the top one — having been entirely defoliated, from its tip about eighteen inches downward, leav- ing only the footstalks of the leaves remaining. I have also taken it on the White Poplar (Popidm tremuloides), to the number of five on one small bush.
The chrysalis resembles closely that of arthemia ; the dorsal projec- tion is smaller and more elliptical in outline ; the depression between it and the thoracic carination, deeper; head-case nearly square in front.
The hutterflij emerges early in August, after eight or nine days in chrysalis. I have also captured it early in May, appearing as if it had survived the winter.
Pyrameis huntera, Sm. Abb.
Larva, head and first segment without spines ; body with rows of black branching spines — brown, with delicately lined bands (yellow, Abbott, black, Fab.) on the anterior of each segment; two dorsal rows of seven white (white and red alternately, Abbott) dots. Changed to chrysalis Sept. 3rd.
Chrysalis, suspended by the tail, yellowish ; moderately angular ; head-case, bifid, slightly projecting, and edged with brown above ;
64
[May
thoracic projection forming an obtuse angle ; dorsal spines minute, of nearly uniform size, brown tipped ; segments with rows of brown dots, and also of brownish markings. Imago emerges in ten days.
The hutterjlt/, usually rare, is met with abundantly some years, flying about clover fields, with the short and rapid flight of the Skippers. Tt is the most numerous about the middle of September. Several years ago, prior to my collecting, I observed at the Adirondack Iron Works in this State, immense numbers of either this species or can/iii, upon and about the blossoms of the common thistle {Cirsium lanrpoldtnm) growing by the road-side. So abundant were they, and so little dis- posed to flight, that any desired number, could in a short time, have been taken by hand. T have also captured himtera on the summit ni' Mt. Marcy.

Descriptions of several new species of North American COLEOPTERA. BY .JAMES H. B. BLAND.
Stapuylinus capitatus, n. sp.
Black ; head fulvous ; fifth and sixth dorsal and all the ventral seg- ments, silvery-sericeous.
//ff/>.— Canada West. (Coll. Ent. Soc. Philadelphia.)
Body black, pubescent and having a few long black hairs scattered over the surface ; head large, subquadrate, broader and larger than the thorax, fulvous, clothed with very short golden-sericeous pubescence, finely punctured, and having several deep, isolated, black punctures, from which proceeds a single long black hair ; eyes small, rounded, black ; mandibles long, acute, shining, fulvous, their tips black, as well as the palpi and the sides and undei'surface of the collar ; antennae rufo-piceous. the basal joint fulvous, apical joints blackish. Thorax subquadrate, slightly narrowed behind, truncate anteriorly and rounded posterierly, finely punctured, densely clothed with very short black pubescence, and having scattered spots of fulvous pubescence, which are more obvious Avheu viewed in certain lights ; dorsal sui'face with a smooth, polished, longitudinal, elevated line, obsoletely defined in the middle ; scutellum velvety-black.

Body blackish-piceous; head coarsely and confluently punctured, deeply excavated between the eyes ; mouth pieeous ; antennae longer than the head and thorax, bipectinate, brown, becoming paler toward the tip, ord joint broader and larger than the 2nd. Thorax black, about equal in length and breadth, coarsely and confluently punctured, sides rounded in front, somewhat sinuate behind the middle, the pos- terior angles long, subacute, cariuated and strongly divergent ; dorsal groove deep, broader just behind the middle, on each side of this groove in front there is a large deep depression ; posterior margin strongly and transversely depressed on each side. Elytra elongate, subconvex, slightly depressed at the anterior fourth, .aides almost paral- lel, being slightly sinuate about the middle, gradually rounded at tip ; striae deep, not distinctly punctured, interstices convex, rugosely punc- tured; abdomen beneath pieeous, finely punctured. Legs pieeous, va- ried with rufous, tarsi pale rufous. Length 12 J lines.
This species differs from the % specimen before me of P. a Hiyainus Lee, by being much more robust, more coarsely punctured, the depres- sions of the thorax, though similarly situated, are much deeper and larger, the striae of the elytra are more deeply impressed and the in- terstices more coarsely punctured. The greatest difi"erence between these two species, however, lies in the proportions of the thorax, which in the present species, is as broad as long and the sides rounded in front, while in anguinus it is longer than broad and the sides nearly parallel. The color of the antenna) and legs is also dififerent.
It gives me pleasure to dedicate this fine species to Mr. B. Billings. Jr., of Ottawa, Canada West, to whose kindness the Society is indebted for this and many other valuable Coleoptera.

Distinguished from G. cyanipennis Say, and G. ahdominalis Bland, by the much coarser punctation and by the color of the antennae and legs; from cyanipoinis it is at once distinguished by the short trans- verse thorax, the shape of which approaches that of ahdomtnaUa, but is still more transverse. It is, however, abundantly distinct from either species.

Gorgopis quadriguttatus. nov. sp. Plate 1, fig. 6, 9 •
Anterior wings pale greyish, very faintly tinged with pale salmon color, the latter shade more prominent along internal margin, with broad, pale olivaceous-brown bands : the first very oblique, joining the internal margin about two-thirds from the base and approximate to the terminal band, not extending above the median vein, and enclosing, between the forks of the submedian vein, two nearly equal sized silvery white spots ringed with black ; midway between the base of this band and the base of the wing is a similarly colored patch on the internal margin ; two similarly colored patches on the costa, and beyond them a second, broad, inversely oblique, irregular band extending from the costa to vein o, faintly tinged with ochraceous inferiorily. A broad sub-api- cal demi-band ; terminal band very wide, narrowest at apex, similarly colored to the other bands, paler towards internal angle. Posterior wings entirely pale salmon color, greyish on the costa, showing a brown- ish sub-apical patch. Abdomen pale salmon-color; thorax, head and antennae olivaceous, metathorax clothed with long salmon-colored hairs. Under surface of both wings tinged with salmon-color, reflecting the markings of upper surface on anterior wings. 9 Exp. 3| inches.
Hah. '• Great Slave Lake." Mr. Ross.
Allied to Gorgopis argenteo-maculatus Harris; the disposition of the median bands on the anterior wings is somewhat different and they are not so largely tinged with ochraceous, the two white spots are much smaller and the apex apparently not so falcate, while the colora- tion of abdomen, metathorax and posterior wings, readily distinguishes the present from Harris' species.
A small collection of unset Arctic Lepidoptera, which included the preceding species, collected principally by Mr. Robert Kennicott, was kindly submitted to me by Mr. Wm. H. Edwards, and contained, among others, the following species : —

Two ( S $ ) specimens, varying in the number and size of the yel- lowish spots on anterior wings.
It seems probable that while Mr. Walker has described the present species as A. americana., Harris, he has also regarded the latter species as identical with the European A. caja, Linn, from which it is readily distinguished by the white band on the collar, scarlet palpal fringe, etc. Mr. Moschler's Arctia borealis is evidently a synonym of this species. while his Arctia caja, W.

Anterior wings deep velvety black, all the veins narrowly marked with flesh-color. A moderately broad flesh-colored band traverses the length of the wing from base to external margin, becoming furcate above internal angle, and upon which, in the terminal half of the wing, rests a series of similarly colored bands resembling the letter K, with the straight stroke turned towards the base of the wing and the upper limb, attaining external margin, reflexed to costa near the apex ; a trans- verse demi-band crosses the disc from the sub-costal to median veins.

On each segment is a trans- verse row of black tubercles, emitting tufts of stifi" bristly hairs of the same hue. Hairs on the two broader segments longer than those on the others. A faint whitish dorsal line from the head to the third segment. Under surface dull-red, feet and prolegs of the same color.." Saunders.
The imago of the present species closely resembles A. virgo Linn., in coloration, and is distinguishable from that species by its smaller size, the stripes on the veins on anterior wings being confined to the vein, linear, not spreading out on either side, and by the absence of central and discal spots on the posterior wings. The larva has also been ascertained by Mr. Saunders to be distinct, as will be seen by his description which I have quoted above.
It afi"ords me much pleasure to dedicate this species to Mr. Wm. Saun- ders, who first suggested its distinctiveness from A. virgo Linn., while erroneously regarding it as Kirby's A. virguncula.
From the absence of comparative allusion it would appear that Kirby in describing his Calliinorpha parthenice, was unaware of the existence of the description of Linnaeus' virgo, and whether or no there be two large distinct forms included under the latter name, which I much doubt, I am of opinion that partlienice Kirby, should be regarded as a simple synonym of virgo Linn. Kirby's description presents some resem- blance to A. Saundersii, but the (S ) expanse given (If in.) is larger. A. partlienice Saunders, appears to me a modification of A. virgo Linn., with brown antennge and apparently broader stripes, but I should hesi- tate to assume a specific distinctiveness upon such small difi'ereuces, the expanse being the same. I believe then to assume but two distinct

species, the one A. virgo Linn., larger, the stripes on the median vein extending on either side beyond the vein itself, the other A. Saun- derxli m., smaller, the stripes on the median vein linear, confined to the vein itself.

Closely resembles M. dtphtheroules Gruen., in all but coloration.
I assume that M. ohliterata will receive additional evidence of its distinctness from 31. diphtheroides Guen., on the discovery of the larval states, and I have for the present refused to regard it as a va- riety of that species; its presence in numerous collections in which the latter is wanting would favor the view of its validity. It appears to sustain a parallel relation to 3L diphtheroides that Lac'mia expultrix m., does to L. cymatoplioroides Gruen., and in the latter ease I have noted larval difi"erenees which will not permit the species to be united. {Proc.

Dr. Herrich-SclirefFer. Korr. Blatt. d. zool. iiiin. Ver. in Regensburg, 1858, p. 153, would refer MicrococUa d'tphthcroides to Hiibner's genus Mnma, I think incorrectly, the habitus of the species being very differ- ent from that of the European Moma orion Linn., to which latter species B./hUnx. H-8. and D. f/rsejii\ m., are more nearly allied. Sub- sequently, Korr. Blatt. d. zool. min. Ver. I860, pp. 71 and 72, the same distinguished authority, recognizing the validity of M. Gruenee's genus GrammopJiOJ-a, would unite under the latter generic name the species included under Microcoelia Gruen., regarding the two genera as identical although placed by M. Guenee in different families. I incline to believe this view correct, while I am as yet prevented, through paucity of material, from making the necessary examinations to establish the fact. M. vinnnhi. m., appears to me the link connecting the two series of species, for, while showing the ornamentation of Microcoelia^ it has much the habitus of Grammopltora hebrsea Guen.

A delicate species with the habitus of G. nebris Gueuee. It differs from the other North American species of the genus in that the ordi- nary spots are of the same color as the median space, and not separated into raised whitish dots, excepting only G. nitela Guenee, in which the ordinary spots may be regarded as obsolete.

Two % specimens varying in size and distinctness of ornamentation. In size this species approaches U. nimbosa Gruen., and E. imbrifera (luen., and in coloration somewhat resembles the European E. tincta V. ; it is however a more robust species than any of these and suffi- ciently distinct from all its generic allies. With Mr. Walker I retain for the present genus the name under which Hiibner arranged the species in his " Verzeichniss," in preference to Aplecta Guen., as Hiib- ner's Enrols perfectly corresponds to M. Gruenee's genus and has deci- dedly priority. I have another undescribed species of Eurois, allied to E. nimbosa and E. nebulosa, from the Rocky Mountains, but I cannot make a proper description frcTm a single individual in indiflferent pre- servation.

Anterior wings pale rose color, shaded with dark yellowish, median lines straight, darker shaded. Basal line straight, succeeded by a straight sub-basal line and dark yellowish shade. Transverse anterior line straight ; median space large, roseate, with a posterior dark yel- lowish shade which is broadest at internal margin. Reniform spot dis- tinct, elongated, constricted ; median shade yellowish, visible at costa. A similar spot to the reniform and approximately occupying the posi- tion of claviform, is visible below the median vein, near the transverse anterior line ; orbicular spot obsolete.

Closely allied to P. xrea Hiibner, from which it constantly differs by its somewhat larger expanse, the larger median space, the straight distinct median lines, the transverse posterior line succeeded by a me- tallic baud and by the presence of a second diseal spot on the anterior wings. Many S $ individuals from Mass., N. Y., Penn., which I have before me are constant in these and other more trifling differ- ences from P. serea. I believe to cite here M. Gruenees " A," which that Entomologist refers as a variety to P. serea on account of an in- termediate individual which he has seen from Florida. Nevertheless I believe with a sufficient number of perfectly coinciding specimens of both species to correctly separate the present under a distinct specific name.
LITOMITUS, nov. gon. Wings broad; anterior pair with the apex acute, external margin rounded, 12-veined, median vein throwing off veins 2, 8, 4, 5 (m.). which are equally strong, 3, 4 and 5 equi-distant at base, costal margin broad, sub-costal cell narrow, receiving vein 6 at the center of its lower marginal vein. Posterior wings broad, 9-veiued, veins 1 and 2 (m. ) free to base, median vein throwing oft" veins 8, 4, b and 6 (m.) equally strong, the three latter approaching at base, vein 5 nearer 4 than (3 at base, veins 9 and 8 (costal and subcostal) diverging at extreme base of the wing. Palpi clothed with short hair, long, porrect, exceeding the head, 3rd article distinct, long, moderately stout, not spatulate ; head small; eyes large; antennae moderately short, slender, very slightly

I refer this genus to M. Gruenee's Poaphilidse, the single species composing it having evident analogies with Phurys and Cellptera. The differences it presents from the latter are small ; the abdomen is not '■crested" in either sex on the first segment nor are the legs clothed with ''cottony" hairs. Mr. Walker, to whom I communicated a specimen, re- garded genus and species as new, while doubtfully considering them as allied to Toxicampa.

Basal half-line narrow, emanating from a very distinct brownish black costal spot ; transverse anterior line distinct, brownish black, broadest at costa, fol- lowed by a darker shade and forming, below vein 1 at internal mai'gin. a broad arcuated spot somewhat similarly shaped to the sub-cellular sign of the genus Piusia^ but inverted. Orbicular spot reduced to a very minute white dot; median shade line narrow, most distinct at costa, irregularly undulate, traversing the wing from costal to internal margins between the ordinary spots ; reniform spot distinct, large, rounded, ringed with a brownish line, with an internal lighter shade, concolorous with the rest of the wing, connected superiorily with the costa by a narrow shade line and succeeded by an irregulary dentate, distinct shade line somewhat projected superiorily and which occupies the position of the transverse posterior line. A very distinct, nearly sti'aight, ochraceous, geminate band, preceded by a lighter shade, tra- verses the wing from costal to internal margins, emanating just before the apex, and joining the internal margin just before the internal angle, the outer line shaded with brownish black. The subterminal line is very approximate to this band, faint, regularly dentate, connecting a series of small distinct black dots on the veins.

Anterior wings silky, pale-blackish mixed with greyish, resembling in ornamentation those of A. pyramidoides Guenee. In the present species the orbicular spot appears more reduced, the transverse poste- rior line more bent, and the costa more convex. Posterior wings cu- preous, blackish-grey along the costa to 3rd superior vein, rest of the wing with a faint, pale reddish tinge, ill-defined superiorily along exter- nal margin, which latter is more excavated than in A. pyramidoides. in which the posterior wings appear proportionally larger.

In the markings of the anterior wings this species nearly imitates A. pyramidoides. the costa is however perceptibly more convex, the coloration paler and the designs more effaced. The coloration of the posterior wings is quite different and they appear at first glance almost concolorous ; these differences, together with its smaller size, prevent me from considering it as a variety of A. pyramidoides^ which latter is moreover a very constant species.

I can detect no differences between C. phalanija, m , and the present species, with which it conforms in the shape of the wings, size, course of the median lines on the anterior, and coloration of posterior, wings, except the distinct black band which follows the transverse posterior line, giving an appearance of narrowness to the sub-terminal space, and the paler coloration of the median space superiorily.
The following species is regarded by some Entomologists as identical with the foregoing, but I am of opinion that it is very distinct. I think it probable, from determinations I have received from Mr. Walker, that C. palseogama, of the British Museum, refers to the present, and not to the species I have above described as C. palaeogama Gruenee.

A. few Lepidoptera Heterocera received by this Society from Pike's Peak, and now contained in its Cabinet, have been determined as fill- lows. A species of Flusia, closely resembling the European P. diver- gens, was preliminarily described on page 274 of the 2nd volume of these Proceedings, as P. vjnea Grrote ; while still considering the species as distinct from its European ally, it is believed to be the species de- scribed as P. nitlcola Walker, with which description the specimen sufficiently corresponds ; the name given it in these pages is accord- ingl}^ withdrawn. Besides the below enumerated, determined speci- mens, individuals were received belonging to the genera Hadena. Anarta, and Cidaria, but their insufficient preservation prevented their specific determination.
