May 2bth, 1868. — This morning I passed by a small grove of Prickly Ash, a mile west of this town, and observing that the wookpeckers had attacked the branches of some dead trees, the trunks of which were barked last July, I made an examination, and found that the bark had been considerably undermined by wood-boring larvae. This work had been done during the latter part of last summer; in the autumn the borers entered the wood, usually by oblique paths, to secure safe winter quarters. On cutting down I found the larvae — footless borers — of whitish and pink-orange colors, about one-fourth of an inch long. In these burrows I found several pink-orange pupae, invariably lying with their heads outward; their long antennae folded over the wing-cases, oblique down on the sides, passing beneath the posterior pair of legs, a little beyond them, and then curving up over the breast reach the head. From these pupae I bred a small Lamiide, related to Liopus alpha. Liopus xanthoxyli, n. sp. — Gray, with bands and spots of blackish pubescence. Antennae about once and a half the length of the body, joints blackish at the articulations ; hoary, mottled with cinereous and light brown between. Ely¬ tra hoary-cinereous, or slightly shaded with light brown, marked with an im¬ perfect broad transverse band before the middle, and with two oblique bands, and many smaller spots of blackish behind the middle; in some specimens the grey predominates, in others black; in a few the bands are almost obsolete, being merely spotted with black. Thorax with two broad longitudinal lines converging to a point in form of the letter V ; each side behind the middle with an angular spine-like projection. Head depressed between the antennae, grey, with some small black spots; on the occiput a posterior median half line, and many small black spots, not equally well defined in all specimens. Beneath cinereous, incisures blackish; legs grey, somewhat spotted with black. Length about .25 inch. Till June 10 th. — I found only a few pup® in their holes in the wood ; but a few days later I took a number of specimens of the perfect insect by beating the Prickly Ash bushes. Examinations of old bushes show the work of former vears. From these observations I conclude that they breed in wood recently dead, never in living wood, nor yet in wood dead for several years. In many of the holes in the body of the trees, I find a small, white silky cocoon, and where this is I never find the pupae of the Liopus. From these, June 20th — 25th, I bred an undetermined species of Iehneumonidse. I also find a white maggot preying on some recently dead larvae. One of these maggots, not yet half grown, appears to have just killed its victim, which is still quite plump, the posterior part a little shrivelled from the sucking of the maggot; these parasites were probably deposited this spring. They soon became pupae, with the naked white legs free. From these — June 15th — I obtained a beautiful little Ichneumonide — also undetermined. I find many small beetles ( Lccmopk - Iceus adustus Lee., and Sacium fasciatum Say) crawling about slowly on the bark of the Prickly Ash bushes. May 23rd. — Saw several of the Sacium fasciatum in the holes of the borers. Observing a small round hole, like a pin hole, in a dead Prick!}' Ash bush, I cut out two specimens of a Scolytide, which Dr. LeConte informs me he has recently named Micracis suturalis .* Upon several occasions, up to the present time, I have beaten Prickly Ash bushes in different localities in the groves within two miles of Mount Carroll, but never found either Micracis suturalis, Liopus xanthoxyli, Lcemophlceus adustus or Sacium fasciatum, except in the one locality on the creek a mile west of the town; no dead trees were, however, ob¬ served in the other localities. The finding of Sacium fasciatum frequently in the borer holes, might lead us to conclude that they feed on the excrements or exuvia of other species. Among the Coleoptera obtained by beating the Prickly Ash bushes, I observe numerous specimens of a small, grey snout- beetle — an undescribed species of Centrinus. I find the trees in fruit, and have collected them from no other trees. Since making the above observations on Micracis suturalis, I have succeeded in obtaining a small number by cutting in the dead wood, where the bark was adherent and where the Liopus larvse had not worked. They are only found in imago now, and in this state appear to have entered; their holes are en¬ tirely free from chips, and I usually found them with their heads inward ; their holes frequently intersect, and wind in various directions; sometimes they have several external openings, and when approached they usually go deeper in, if possible. I never took one by beating on the bushes. I saw one on the trunk of a Prickly Ash, but it escaped by falling to the ground. June 19th. — I obtained from beneath the bark, a small species of Chalcididae ; also a larva of a species of Scymmus from the holes of the borers. I am indebted to Dr. LeConte for determining the Coleoptera above noticed. Mount Carroll, Illinois, July 1, 1868. A brief Extract from Notes on Grape Vine Borers. April 2b th, 1868. — When examining dead wood of Isabella and Clinton Grape vines, I find many of the vines literally riddled by some kind of borer; and in these galleries I observe many specimens of Amphicerus bicaudatus, Say. A * Trans. Am. Ent. Soc. ii, 165. IX small proportion of them were living; they doubtless passed the winter in the perfect state, and as the vines were exposed to unusually severe weather on the trellises, many of the insects died; the dead specimens were pa'ssibly fit for preserving, had it been desirable. I saw two male specimens, one dead, the other living. The finding of the Amphicerus bicaudatus Say, under these cir¬ cumstances, associated with A. aspericollis Germ., confirms the opinion of Dr. LeConte, that the two are sexes of one species. Upon a subsequent occasion, I found two A. bicaudatus just in the act of boring into grape vines immediately above the buds ; they had entered about once and a half their length in limbs frost-killed during the last winter. These observations remind me that Dr. John Hostetter, of Mount Carroll, about five years ago, informed me that he had found a grape vine borer in its different stages. I find in the vines three species of Coleopterous larvae ; one rather rare, footless, yellowish-white, with black horny mandibles, length .30 inch ; from these, after eighteen days in pu- parium, I bred Callidium avicenum Say. Another is a thick wrinkly grub, with a hoary-brownish line on the upper part of the abdomem ; thorax extremely heavy, body curved so that the extremities come together, legs quite hairy. I placed about a dozen specimens into a box ; they refused to eat. I never saw them crawling, they were always curled up, and when handled, tumbled about like balls, the feet were constantly in motion. These all died in the course of two or three weeks without becoming pupae; their greatest length is .30 inch. Still later, I obtained two much larger grubs; these are yet in the larval state in the vine; I can only conjecture that they may be the larvae of Amphicerus bicaudatus. A third larva, a grub somewhat similar to that noticed above, but smaller and more slender, is very abundant; it is white, without the dark spot on the abdomen, and curls up as the other when removed from the wood. May 1 bth. — Many of these larvae have become pupae, and on the 10th of June most of them were in the perfect state, and only one larva was seen. These developed into Lyctus opaculus, Lee., and on the 1st of July I took the last ima¬ go out of the grape wood. These were so numerous in many vines as to eat up the wood entirely, the bark alone sustaining the vine. I am convinced that they only feed on wood recently dead, more especially because they are so often huddled together so closely; it is quite apparent that they do not inter¬ fere with living saj)py wood. I am inclined to believe the same regarding all these three species of grape vine borers. If this is a correct conclusion, they will not damage the vines. Associated with these borers, I found at least three distinct parasites ; two identical with the undetermined Ichneumonide mentioned in my Notes on the Prickly Ash insects; and a third a naked, black, footless pupa found in early spring in the borings of the coleopterous larvae, which probably passed the winter in the stems; these developed an undetermined species of Chalcid- idae, which presents the following characters; — Head, thorax and anterior part of abdomen greenish, with purple, golden and metallic reflections; posterior part of abdomen steel-blue; legs and first joint of antennae reddish ; remainder of antennae black ; wings with two smoky transverse bands ; the antennae equal one-fourth the anterior wing in length; length of body one-fourth of an inch. Several other insects were observed in connection with these observations, but of which I did not learn sufficient to notice at present. Mount Carroll, Ills., July 1, 1868. X October 12, 1868.

From the Author. Dr. Horn made a few remarks concerning Cossyphus, a genus considered from its tarsal characters as being a Teuebrionide Coleopteron, showing how¬ ever a peculiarity of structure unknown until now, excepting among the Rhyn- chophora. The character was first observed by Dr. LeConte in the latter group of families, and its systematic value pointed out before the National Academy a year or two ago, and consists in the union of the edges of the pros- ternal epimera on the median line behind the prosternum, so that |\y/| | the latter never attains the margin of prothoracic segment, and is consequently never near the mesosternum. The accompanying il¬ lustration exhibits this peculiar structure in Cossyphus, which appears to indi¬ cate the possibility of the removal of the genus from its present position to the head of the great Rhynehophorous section of Coleoptera. Dr. LeConte followed in remarks regarding the interest of the observation here made known, and explained at some length the peculiarities of structure of the under surface of the prothorax in the different families of Coleoptera. , - 0 - November 9, 1868.

BY E. T. CRESSON. Part I. The species comprised in this catalogue were collected at the Haci¬ enda del Potrero, near Cordova, Mexico, and presented to the Am¬ erican Entomological Society by Prof. F. Sumichrast, of Orizaba, — a most excellent and zealous collector, not only of entomological spe¬ cimens, but of all branches of Zoology. Py his indefatigable labors, large and beautifully preserved collections of Hymenoptera have been made in the environs of Orizaba and Cordova, and the prospects are that the handsome and extremely interesting fauna of that part of Mexico, will soon be thoroughly worked up. As yet, very little has been done by European authors in making known to science the Hymenoptera, from America, forming the section Terebrantia — probably the most numerous of the two sections in the number of genera and species, and comprising insects of brilliant colors, of beautiful ornamentation, and of very curious and anomalous forms. The Aculeata seem to receive, I may as well say, all the attention, and the Terebrantia comparatively none. It is true that the families of the last named section are, in general, more difficult to study, especially the subsection Entomopliaga, by reason of the small size and the ex¬ treme variability of form and coloration ; but this is no good cause for discouragement. However difficult and perplexing the study may be, an attempt to work up the genera and species must be made, no matter how imperfectly done. There are no great risks to run in creating synonyms — apart from those unavoidably made where the sexes are so very dissimilar in coloration — because so little has been done. I am well aware that what little I have achieved, towards working up the Ichneumonidae of this country, is very imperfect, and will have to ( t ) wav, 1868. TUANS. AVER. ENT. SOC. E. T. CRESSON. be gone over many times before anything approaching perfection can be arrived at; but this is the case with all families of insects where the species are very numerous and the generic and specific characters so improminent as in this great family. When studying and cataloguing the species of the genus Ichneumon, collected north of Mexico, (having at the time very few from south of that line.) I had but little difficulty in deciding what species properly belonged to that genus, and Hoplismenus, Joppa and Trogus seemed to me to possess characters by which they could be readily separated from Ichneumon and from each other ; but since the examination of the collection now under consideration from Mexico — a recent arrival — I find so many intermediate forms, that I actually hesitate to say what, is an Ichneumon , an Hoplismenus , a Joppa , or a Trogus. If I confine myself to typical generic forms, I have left a number of species I feel at a loss to say to what genus they properly belong. In this dilem¬ ma, I have for the present compromised the matter in my own mind by provisionally retaining all the four above named genera, and placing in them such species as seem most natural, and referring the most doubtful species to Ichneumon. This seems to me the best plan to adopt for the present and until a more elaborate study can be made of their natural affinities. Family ICHNEUMONIDiE. Genus ICHNEUMON, Linn.

On the habits of the Mexican species of the . During the summer and autumn of 1867 I had the opportunity, in company with my friend Dr. S. Lewis, of being connected with the surveying party under charge of Gen. W. W. Wright, for the exten¬ sion of the railroad above mentioned. Our journey in part lay through a region previously but little known, the valley of the Purgatory, and the Raton Mountain, and as was to be expected, a moderate number of new species of Coleoptera were found, several of which are very in¬ teresting additions to our fauna. I have added in a few instances spe¬ cies from neighboring regions which were previously in my collection. CICINDELA L inn. C. ci'marrona, nigra, subtus nitida, supra opaca, mandibulamm basi labroque albis, hoc tridentato, fronte pilosa utrinque fortiter rugosa, thorace trapezoideo, postice angustato, lateribus antice solum rotundatis, dorso confertim rugoso, impressionibus transversis profundis; clytris thorace fere duplo latioribus, granulato-punctatis, margine apicali diaud serrato, signaturis albidis notatis, viz: vitta submarginali pone liumero et ante apicem dilatato, fasciaque me¬ dia obliqua nonunquam paulo eurvata, vel obtuse angulata. Long. 14 — 1 f* mm. South of Raton Mountain - six specimens collected by Dr. Lewis. One specimen has the white markings of the elytra much more slen¬ der and the marginal band is interrupted before and behind the mid¬ dle, presenting the same form as in C. ancocisconensis , except that the medial band descends obliquely from the obtuse angle, instead of being- curved ; but on comparison it differs not only by the color and mark¬ ings, but by the thorax being broader in front, less rounded on the sides, convex on the disc, and also by the more stout form, and by the apical margin of the elytra being absolutely free from serration. The palpi are entirely black in both sexes; this character with the smooth apical margin of the elytra places this species in group vi. of my revision of Cic-indelae, Trans. Am. Phil. Sac. xi, 36, near 0. pur¬ purea with which it agrees in form and sculpture. It is perhaps the American analogue of the Russian C. distant s, which is placed by Chaudoir in a different group. (7) TI!

Long. 4‘5 mm. Under pine bark at Canada de las Diegos, New Mexico. The punc¬ tures of the head are a little smaller than those of the thorax and ely¬ tra. hut those of the dorsal surface of the abdomen are quite as strong as those of the thorax, though not as rugose as those of the elytra. This species differs from all previously described by the strongly marked punctures of the dorsal abdominal segments.

Long 3 mm. One specimen. New Mexico. Of the size of 0. bicolor , but some¬ what broader and more regularly oval : the rows of punctures of the elytra are very hne, and scarcely visible. This species belongs to the same division of the genus as O. bicolor , having the metastermum con¬ nate with the mesosternum, and protuberant between the middle coxae.* 0CH0DAEUS Lcp. Ln the vicinity of Canon Dlanco, New Mexico, 1 collected six spe¬ cimens of this genus, which Hew into my tent attracted by the light of the lantern. They differ greatly in size, and in the sculpture of the head and elytra, and in comparison with other specimens before me from the collections of Mr. Ulke and myself, indicate that the species of North America are more numerous than has been heretofore suspec¬ ted. Much larger series of specimens must be obtained before the study of the genus cau be regarded as even moderately perfect. The six specimens represent four distinct forms, none of which are precisely like the three species previously in my collection. J have endeavored to define the most prominent differences between them, and two additional ones now before me, in the following table : * I a vail myself of the present, opportunity to describe a beautiful species of OUbrus, found by Mr. Ulke in the interior of the state of New York.

In opacus, musculus and simplex the striae of the elytra are very slight¬ ly impressed, their punctures iu opacus and musculus are much larger than those of the intervals, which are arranged in triple series : in sim¬ plex the punctures of the striae are scarcely larger than those of the intervals, which are closer and less regular than in the other two. In biarmatus the margin of the front is curved, but more thickeued than in the preceding, so that the front appears concave, and at the junc¬ tion of the middle with the lateral lobes, there is on each side a small erect tubercle; the striae of the elytra are deep, strongly punctured and the puuctures of the intervals irregular. In complex and sparsus the punctures of the head and the intervals of the elytra are much more distant than iu the other species, though more so in sparsus than in complex. 0. striatus And pectoralis agree in size and sculpture, but differ in the form of the head between the back part of the eyes ; in striatus (Arizona, collected by Dr. Webb), there is a very well defined trans¬ verse ridge, while in the New Mexican pectoralis there is merely a very gentle swelling, slightly impressed at the middle, forming two faint tu¬ bercles. The prosternum is longitudinally very prominent in the spe¬ cies last named, but not in any of the others. 0. opacus and musculus agree in the form of the front and general sculpture, except that the thorax of the former is more densely granu¬ lated, and the punctures of the intervals of the elytra are more nu¬ merous and less regularly arranged in triple series. The hind femora in musculus are armed at the tip with a large acute 52 JOHN L. LECONTE, M. D. somewhat recurved tooth ; in striatus and complex the tooth is smaller, broader and not quite so close to the extremity ; in biarmatus it is very small, and quite remote, about one-third from the apex; the thighs are not toothed in the other species. It is difficult to determine to which of these species is to be referred O. americanm Westwood, (Trans. Ent. Soc. London. 2nd ser., ii, 06) : the description and figure represent the anterior margin of the front as biangulated, and would seem therefore rather to refer to 0. simplex than to musculus. In consequence of the unexpected increase in the number of species, it is safer to await reference to the typical’specimen in order to fix definitely the synonymy. The Mexican 0. lurldus Westw. (lor. cit.') seems to resemble pecf.o- r.alis Lee., above described, but the tubercles of the vertex are said to be prominent, and the peculiar form of the prosternum seen in the latter species is not mentioned.

Long. ID'S — 12 mm. Two males and a female collected on the Smoky Hill river. This dif¬ fers from the previously known American species by all the tarsal claws being acute and undivided; it therefore belongs to the group Rhom- boni/x Hope. The body is narrower than in our other species, being- proportioned nearly as in Lachnosterna longitarsis, but less cylindrical. The club of the antennse in the male is one third longer than the other portion, but in the female is not longer than the joints 2 — fi inclusive. SANDALUS Knoch.

Long. 15 mm. Two females found on the Arkansas, and one south of Raton Moun¬ tain, by Dr. Lewis. This species agrees with S. niger and ca/lfomicus by the sides of the thorax being oblique and nearly straight, but differs AMERICAN COLEOPTERA. 5d from them and agrees with S. petroph/a, by the more opake and densely punctured thorax, with larger conspicuous punctures intermixed ; it differs front all by the elytra being more deeply concave and more nar¬ rowly margined at the base.

S. rufieollis, rotundato-ovalis, nigro-piceus nitidus, punctulatu? subtiliter pu- bescens, capite, thorace, macula elytrorum ovali comrnuni, antonnis pedibusque rufo-testaceis : thorace interdum macula apicali nigra. Long. 3 him. Two specimens collected by Dr. Lewis south of the Raton Mountain ; I have also seen specimens from Texas. This species agrees in size form and sculpture with S. centralis, but differs by the head and thorax being pale reddish-yellow, and by the discoidal spot of the elytra be¬ ing much larger. PHOTINUS Lap. emend. Lac. P. flavicollis, elongata, nigra, thorace seinicirculari, laete flavo, lateribus et apice punctatis, subdiaphanis, disco medio nitido laevi canalieulato : elytris gra- nulatis, margine late explanato, dorso utrinqiie linea elevata parum conspicua; abdomine segmentis duobus ultimis pallidis, antepenultimo margine postico pallido. Long. S’5 mm. . A very distinct and beautiful species found clinging to plants in the neighborhood of the Purgatory canon and the Raton Mountain. It seems to belong to the same section of the genus as P. nigricans , deci- piens and fcnestralis , but differs from them by the last two segments of the abdomen being pale, though they have not the appearance ot being luminiferous.

Long 7 — 15 mm. Abundant near Fort Union. New Mexico. On account of the pe¬ culiar marking of the elytra I at first supposed it to belong to Tetra- onyx, but on examination found it to possess all the characters of a ge¬ nuine Epieauta. The thorax is more robust than usual, being about, one-third wider than its length ; the two rounded black spots are so large as nearly to meet on the median line. I desire in the name of this elegant species to commemorate the friendly assistance rendered to us in our scientific pursuits by Capt. Lyman Stuart, late Commissary of Subsistence, U. S. V., a member of the expedition. We are indebted to him for a series of specimens collected in the upper part of the Ltio Grande Valley, on the road from Fort Garland to Santa Fe. TOPOSCOPTTS Lee. (n. g. Rhipiphoridse.) The single species of this genus represents on this continent the rare Evanioeera Dufourii Latr., of Hungary, and agrees with that species in size, form and sculpture, so closely that without examination it would uot be readily distinguished. The generic differences are, however, very great, the chief ones being as follows : The vertex is less elevated than in Evanioeera ; the eyes are divided into two portions, connected by a slender line of smooth corneous ma¬ terial, which is destitute of lenses, while in Evanioeera they are only deeply emarginate. 'I'he 3d joint of the antennae of the male is longer, with a basal process about four-fifths as long as the processes of the following joints, while in Evanioeera the 3d joint is short, prolonged externally into a process one-fifth as long as those of the following joints. The side margin of the prothorax is more developed, extending from the hind angles nearly to the apex. The claws are not finely pectinate, as in Evanioeera , but bifid at tip, and armed with three slight teeth, somewhat as in Ancholremus Gerst. T. Wrightii, elongatus piceus, confertissime punctulatus,pube subtili einereo- sericante dense vestitus, thorace a basi antrorsum angustato, lateribus reetis obliquis, latitudine baseos vix longiore, basi profunde bisinuata, angulis posti- cis productis acutis, lobo medio truncato : elytris parallels, apice conjunctim rotundatis.

Femina latet. Ten male specimens were collected on gramma grass at the crossing of Tccalote creek, south of Las Vegas, Now Mexico. We sought diligently for the females, but without success. In comparison with Eoaniocera Dufourii , besides the generic distinctions above mentioned, the punc¬ tuation is much finer, and the pubescence shorter, finer and more seri¬ ceous. 1 desire in the name of this beautiful and interesting addition to our fauna, to commemorate the ability of Gen. W. W. Wright, the Chief Engineer and Commander of the Survey on which the species described in the present memoir were collected. His attention to the comfort and safety of the party while traveling through a hostile Indian coun¬ try will not be soon forgotten by any of bis companions; while the skill with which the more difficult portions of the route were examined, and the labors of his assistants directed to the most easy methods of surmounting the difficulties, will commend itself to every admirer of correct engineering. TACHYGONUS Schonh. T. centralis, brevissime ovatus, niger nitidus, setis griseis erectis vestitus, tho- race puree fortiter punctate, lateribus parce pallide piloso, versus angulos posticos fasciculo pallido ornato; elytris grosse seriatim punctatis, fascicule pallido post- scutellari ornatis; rnctasterni lateribus albopilosis, antennis testaceis, tarsis non- nunquam testaceis. Long. 1'5 mm. Trinehera Pass, on Rhus aromaticum. With the exception of the white hairs on the sides and at the posterior angles of the thorax, the fasciculus behind the scutellum, and the less dense white hairs of the sides of the metasternum, the body and legs are clothed with erect bristles which appear black except in certain lights, when they appear dark gray. The rostrum is smooth and shilling, with a row of strongly marked punctures above the antennal and a few scattered punctures on the side; head thickly punctured, eyes almost confluent. Thorax sparsely but strongly punctured. Elytra with rows of very large punctures, intervals marked with a series of setiferous punctures and a few transverse wrinkles; a well defined bunch of white erect hairs on the suture just behind the scutellum. Antennae testaceous, or yellow ; tarsi sometimes testaceous, sometimes blackish. Hind femora armed beneath with five or six small teeth. DONACIA Fabr.

Long. 9 mm. One specimen collected on the Smoky Hill liver. This species dif¬ fers from all the others in my collection by the dense pubescence of the upper surface ; the body beneath is clothed as usual with silvery short dense hairs. By description it resembles the European I), tommtoxa Ahrens, in many of its characters, but I have had no opportunity to compare it with a specimen of that species. COSCINOPTERA Lac. C. axillaris, oblonga.subcylindrica, nigra, subtus densissime, supra sat dense cinereo-nubescens, labro glabro; thorace confertim punctate, linea dorsali fere obsolete laevi ; elytris fortius punctatis et rugosis, macula humeral! subquad- rata laete rufa ornatis. Long. 4 — 5 mm. Abundant on the Arkansas and and Smoky Hill rivers. The 4th joint of the antennae is scarcely longer than the 3d, but somewhat broader.

Long. 6'5 mm. Two specimens. Arizona, Dr. lb J. D. Irwin, TT. S. A. A fine species, easily distinguished by the large quadrate red spot, which occupies the anterior third of the elytra, except the suture and the inner half of the base, which remain black. The 4th joint of the antennae is almost twice as long as the 3d, and nearly as wide as the 5th ; the 3d joint is rounded, and smaller than the 2d. GRIBURIUS Hald.

Long. 6 mm. Mas segmento ventrali ultimo apice fovea magna circulari excavato. But two specimens of this most beautiful species were found by Dr. Lewis, south of the Raton Mountain. In comparison with G. lar~ vatus the thorax is shorter, having nearly the same proportions as in G. scutellaris , but more rounded on the sides ; the punctures of the head and thorax are less distant than in either of those species, and the striae of the elytra are composed of more closely set and smaller AMERICAN COLEOPTERA. 57 punctures, the punctures between the oblique abbreviated stria and the suture are confused. CHRYSOMELA Linn. C. continua, ovalis, supra ferruginea, thorace ad latera grosse punctata, mar- gine apicali lateribusque pallidis; elytris pallidis, vitta suturali antice diver - genle, alterisque utrinque duabus latis postice connexis epipleurisque ferrugi- neis; subtus obscure ferruginea, piceo variegata ; antennis articulis ultimis quinque piceis. Long. 6-5 — 7 mm. South of Raton Mountain, Dr. Lewis. Of the same size, form and sculpture as C. conjunct-a , and differing only by the absence of sub¬ marginal elytral spots and by the vitta? being broader, not sinuous, and not interrupted. The stripes, as usual are limited by well marked series of punctures ; the sutural stripe is nearly smooth, the two dorsal ones are strongly punctured, the pale ground of the elytra is very feebly and sparsely punctured, and there are three rows of punctures between the outer stripe and the margin ; the inner two of these are abbreviated. I have seen specimens of this species from Arizona. C. conjuncta Rogers, Proc. Ac. Nat. Sc., Phil. 1856, 34, tab. 1, fig. 9. A large series of specimens collected on the Smoky Hill and Ark¬ ansas rivers shows that C. stolata Suffr., and C. pallida Bland, are merely varieties of this species. In the first named, the dorsal vitta? of the elytra are entire, and united behind ; in the second the inner vitta is interrupted in front of the middle ; iu another variety the in¬ terruption is behind the middle, and the outer vitta is more sinuous than usual; in C. pallida the inner vitta is interrupted both before and behind the middle, and the outer one is still more sinuous, with a tendency at the outer angle of the sinuosity to the formation of a se¬ parate spot. LIJPERUS Geoffr. L. luteicollis, niger, capite nitido paree subtiliter punctata, thorace flavo, dense punctulato, longitudine duplo latiore, apice fere truncato, lateribus cum basi rotundatis, angulis anticis subrectis, posticis obtusis rotundatis; elytris dense punctulatis, nigro-cj'aneis, hie inde obsoletissime striatis antennis articulo 3io praecedente sesqui longiore; 4to illis conjunctis aequali.

Long. 3 mm. Kansas: three specimens given me by Mr. Ulke. This species pre¬ cisely resembles Pli. gentilis Lee., ( Proc. Acad., 1865, 208), except that the elytra are entirely black, instead of having the suture and lateral margin yellow ; the lateral black vittae of the thorax are also wider, leaving the reflexed marginal bead yellow. DIABROTICA Chevr. D. blandula, elongata^ pallida, capite postpectore. vittis elytrorum tribus in- fuscatis; thorace quadrato, flavo, medio transversim profunde excavato ; elytris punetulatis, obsolete striatis; antennis fuscis, basi pallidis. Long. 5 mm. Variat, elytris pallidis, sutura paulo infuscata. Smoky Hill river, on the wild gourd. This species has the 3d joint of the antennae much longer than the 2d, and nearly equal to the 4th. differing thereby from D. lortgicornis , to which at first sight it bears a strong resemblance. Ry an error of print in the synopsis on p. 212, of the Proceedings of the Academy for 1865, the 3d group of the genus to which the present species belongs is stated to have the 2d and 3d joints of the antennae equal, while in fact the 3d joint is longer, as in the first group. This species differs in sculpture from D. vitfata by the elytra being only very faintly striate. The synoptic table should therefore be corrccte 1 as follows : A. Third joint of antennae longer than the second : a. Thorax not impressed; elytra no.t striate . Group I b. Thorax deeply impressed; elytra striate . Group 3 IS. Third j oint of antennse equal to the second : a. Thorax with two faint foveas; elytra even, not striate . Group 2 b. Thorax with two deep excavations; elytra carinate towards the sides . Group 1 D. lemniscata, elongata, nigra nitida, thorace quadrato, lateribus fortiter mar- ginatis, subsinuatis, angulis omnibus subprominulis, dorso profunde biim- presso ; elytris subtilissime alutaceo-granulatis, sat dense subtiliter punctatis, fortiter marginatis versus latera subsulcatis et carina utrinque abbreviata ob- tusa ornatis, Havis vitta lata suturali, alteraque lata ab humero fere ad apicem extensa nigris. Long. 5-5 mm. South of the Raton Mountain, and at Fort Union; not rare. Allied to D. fongicornia and atripennis , and belonging with them to the 4th AMERICAN CO LEOPTER A. 59 group ; differs from the former by the elytra being less strongly punc¬ tured, and not striate; from both by the arrangement of the colors of the elytra, which are yellow, with a broad common sutgral black vitta, and a broad dorsal vitta extending from the base nearly to the tip ; or they may be described as black with a narrow dorsal vitta, the lateral and apical margins yellow. D. virgifera, pallide flava, ore. occipite, antennis, scutello, postpectoris late- ribus, femorum linea superna, tibiis tarsisque infuseatis; prothorace quadrate, latitudine vix longiore lateribus fortiter marginatis subsinuatis, angulis fere rectis, dorso bifoveato : elvtris vitta conimuni suturali, alteraque utrinque ab liumero fere ad apicem extensa nigris, subtiliter punctatis, striis, (vel potius sulcis), sat profundis impressis, lateribus fortiter marginatis: antennarum ar- ticulo :tio praecedente sesqui longiore, 4to tamen vix dimidio aequante. Long. b — 6 mm. Two specimens found on the wild gourd near Fort Wallace. This species is intermediate both by the sculpture and the relation of the antennal joints between those of group 3 and 4. though rather to be classed with the latter because the striae of the elytra are more grooves than strim, and are not marked with rows of punctures ; the elevated ridge next the margin is more strongly marked than the inner ones. The antennae are three-fourths the length of the body, the 2d joint is about two-thirds as long as the 3d. but the latter is only one-half as long as the 4th; all the joints are dark colored except the 1st. which is testaceous, with a dirk line above. - o - COLEOPTERA of the U. S. Coast Survey expedition to Alaska, under charge of Mr. George Davidson. BE JOHN L. LECONTE. M. T>. I have recently received from Mr. George Davidson of the U. S. Coast Survey a small collection of insects made by him and his assist¬ ants Dr. Albert Kellogg, and Mr. W. G. W. Harford, during his re¬ cent very successful exploration of our newly acquired territory, Al¬ aska. Although the number of new species is not large, T have thought it desirable to make known the results as speedily as possible, in order that encouragement may be given to chiefs of other parties who may he placed in a position to do service to collateral sciences by knowing that their labors are fully appreciated ; and that those who are not ex¬ posed to the toils and dangers of held service, will not permit the results their work to be lost. It has been my privilege on former occasions, to acknowledge my obligations to Mr. Davidson for large and valuable collections from our Pacific States. The collection contained, besides species of hymenoptera. hemiptera and diptera, 68 species of Coleop- 60 JOHN L. LECONTE, M. T>. tera, most of which have been already described: of these It are re¬ cognised by me as belonging to Alaska, and 54 to California. CYCHRUS Fabr. Specimens of 0. crista tus are contained in the collection, and give me the opportunity of adding to the present communication some notes on the species of this genus which have been found in our Pacific pos¬ sessions. It happens by a fortunate coincidence that I have received from Dr. Horn about the same time, specimens of C. velutinus Men. 1 have also seen in the collection of Mr. Hike a specimen of G. angu-- latus Harris ; of the described species, therefore, only 0. disso Zulus Schaum and G. subtilis Schaum, remain unknown to me. .V.

VELUTINUS. — Though closely allied to C. angusticollis this spe¬ cies is very easily distinguished by the bluish-black color, destitute of lustre, and by the thorax being narrower, more gradually narrowed be¬ hind, and more finely margined ; the elytra are striate in the same man¬ ner, with approximate rows of small points, but three of the intervals are wider and more obvious, and the margin is very dark blue instead of green. Specimens were collected in Southern Oregon and given to me by Dr. 01. H. Horn. 5. C. cristatus Harris. — This species is evidently C. reticulatus Motsch.; the description of Mannerheim (Bull. Mosc. 1853,) is quite characteristic. All the specimens T. have seen are from Northern Cali¬ fornia. 7. C. OBLIQUUS, n. sp. — The single specimen which 1 designate by this name differs from all the others before me, except 0. marginatus. by the thorax being strongly but gradually narrowed behind, with the sides oblique and scarcely sinuate, not constricted. The elytra are broad and ventricose as in C. punctatus ; the striae are deep, strongly punctured, and the intervals are narrow and interrupted towards the tip and margin. The color of the thorax is a very dull opake black, as in C. punctatus. California, near Sacramento. Mr. S. S. Rathvou. 10. C. constrictus Lee. — This species, of which I found two males near New Almaden quicksilver mine in California, differs from C. ven- tricosus only by the thorax and elytra being rather broader, while the insect is much smaller. It is evidently the species figured by Mots- chulsky as C. interrupt us Men. 11. C. VENTRICOSUS. — I learn by the remarks of Dr. Sehaum, ( Bcrl . Eat.

The ely¬ tra in the last named species are more than one-half longer than their width, while in P. crassus they are very distinctly broader, being only about one-third longer than their width. The episterna of the mesothorax in all of the specimens of both species before me, attain the middle coxal cavities as distinctly as in any species of Sea rites* which I have examined ; not at all as in Mis- codera and other Broscini, in which they are completely cut off from the coxal cavities.

Long. 4’5 mm. One specimen, California. This species is easily known by its very inflated form, resembling in outline Amphicyrta simplicipes. The head is more strongly punctured than the thorax ; the latter is at base more than twice as wide as its length; it is strongly narrowed in front, and much rounded on the sides, the apex is broadly rounded at the middle, and the base is truncate; the apical angles owing to the com¬ pression of the sides appear sharp and narrow, the basal angles are nearly rectangular. The elytra arc feebly and finely punctured, a little wider than the thorax, and but little longer than their width, much deflexed behind, and conjointly rounded at tip. S. nitida Motsch., from Alaska, resembles this species in pubescence, hut is very much narrower, and the elytra are more distinctly punc¬ tured.

Long. 5 mm. One specimen. California. This species is allied to T. punctatus Bone., but differs by the striae of the elytra being very fine, and but slightly impressed; they are marked with distant punctures larger than those of the intervals, which are arranged somewhat in two irre¬ gular series. T. sericeus, fuseus subrufescens, pube helva appressa brevi dense vestitus, capite punctulato, bicarinato, carinis integris, oculis profunde impressis; tho- race confertim punctato; elytris striis bene impressis, punctatis, interstitiis subbiseriatim punctatis; antennis obscure ferrugineis, tarsis flavo-testaceis. Long. 2 'b mm. Three specimens from San Francisco given me by Mr. Ulke. This species resembles i.n form T. Chevrolatii Bonv., but the head is more strongly bicarinate, and the pubescence is much shorter, finer and denser; by this last mentioned character, it differs from all the other species known to me. PACTOPUS Leo. (n. g, Throscidse.) This new genus is founded upon an undescribed Californian insect, resembling in its characters and form Throscus, except that the anten¬ nae instead of being clavate are fusiform, and the hind tarsi are re¬ ceived in deep narrow grooves impressed on the first, second and third ventral segments in the same manner as the grooves for the middle tarsi in both genera are impressed on the metasternum. It will therefore be only necessary to give at present a description of the antennae to enable this genus to be recognized. Antennae a little longer than the head and thorax, received in very deep sinuous grooves, which terminate in the space under the hind angles of the prothorax; 1st joint obconical, nearly twice as long as the 2d, which is slightly transverse; 3d — 7th nearly square, closely articulated, about equal in thickness to the 2d, 8 — 10th very little larger, also quadrate and closely united, 11th one-half longer, pointed at the tip. Tarsi long and slender, received in grooves, which are well defined ; those for the middle pair are on the metasternum, divergent, and <34 JOHN L. LE CONTE, M.

Long. 5*5 nun. California; one specimen given mehy Mr. H. Ulke. I have seen one also in the collection cf Dr. 0. H. Horn, to whom it gives me much pleasure to dedicate this interesting addition to our fauna, in cbmmemoration not only of his continued labors during several years, in our l’acitic States, but also of the many valuable observations on the Coleoptera of those regions published by him since his return. EXOPIOIDES Guer. E. iucisa, rufo-picea, elytris obscure ferrugineis, supra subtilissime, subtus longius pubescens ; capite dense granulato, inter oculas linea frontali transversa impresso, occipite transversim impresso, foveaque media nitida insculpto; tho¬ race capite paulo angustiore, ab apice sensim augustato, latitudine apicis baud longiore, valde convexo, dense subtiliter granulato et rugoso, apice vage, bas: fortiter licet anguste marginato, dorso canaliculato ; elytris cylindricis postice declivibus, apice singulatim emarginatis et bidentatis, basi punctatis, postice sensim granulatis. Long. 13 mm. One specimen, California. This interesting species has the form of Polycaun , but differs from that genus by the antennae having only 1<> joints; and of these 10. the 3d and 4th are really connate, and only a slightly sinuous outline is left to indicate the compound nature of the joint. The labrum is larger, more prominent and more deeply emar- ginate than in P. Stoutii and ovipennis, but scarcely more so than in P. exesus ; in P. pubescens the labrum is very transverse, and not emarginate. The 4th and following joints of the antennae of the two species first named are much longer than the 3d, in the last two the 3d and the following to the 8th are equal in length. In the first two the tufts of hair on the 2d and 3d tarsal joints are very short, in the last two much longer, and in Exopioi.des still longer and denser, so as to closely resemble membranous lobes. It is proper to add to the characters given above that the front tibia* of Exopioides are shorter, and more triangular in form, and that the terminal hook is stouter and more curved than in Polycaon ; the ony- chium of the last tarsal joint is quite distinct. AMERICAN LEPIDOPTERA. 65 On the North American FLATYPTERYGINAE. BY AUG. R. GROTE, Curator of Entomology, Buffalo Society of Natural Sciences. Through the kindness of Prof. P. C. Zeller, I have recently been able to see Laspeyres’ article on the genus Platypteryx in the publica¬ tion of the Gessellschaft Nat. Freunde, Berlin, 1803, a work which has now become extremely rare. The date of this work shows that instead of being anterior, as I had considered it (. Proc . Acad. Nat. Set'., Phila., 1862), it is posterior to the description of the same genus under the name of Drepana, by Franz v. P. Schrank, in the Fauna Boica, Vol. 2, p. 147 — 155 of this Author, and which bears the date of 1802. In this latter work the type of Schrank’s genus is the European D. sicula; Schrank also includes the remaining European species, adding, however, an European Noctuid, misled by a coinci¬ dence in the shape of the primaries. Laspeyres does not fall into this error, but accurately and laboriously circumscribes the genus, under which he includes the entire group now regarded as a sub-family of Bombycidae — the P/a typtericidae of Stephens, for which the cor¬ rected form Platypteryginae should be retained. The genus Platyp¬ teryx is divided by Laspeyres into sections : “ Fam. A : Alis falcatis ; Fain. B: Alis subfalcatis; Fam. C : Alis rotundatis.” These divi¬ sions are demanded by the structure of the moths, and are afterward- considered as distinct genera by the English Entomologists, Leach and Stephens. Laspeyres’ Fam. A contains the main body of the species, this author considering the European P. fahida typical of the section. For this section Stephens retains the name Drepana, Schrank , under which the genus is primarily indicated. It is to this that our two North American species, described by myself ( Proc . Acad. Nat. Sci., p. 59, 1862, and p. 346. 1863), belong. For Laspeyres’ Fam B, the English Author retains the generic term of Laspeyres, who n stricted this section to the single European species P. lacertinaria. We have a nearly allied species in the United States, and which re¬ presents the genus with us. It is the Edapteryx bilineata of Dr. Packard. This Author (Proc. Ent. Soc., Phil., p. 375 — 376, 1864 , overlooks the fact that his genus and species have a European repre¬ sentative,* which indeed so closely resembles Dr. Packard’s E. bili- * Equally ignorant of this fact at the time, I figured Dr. Packard’s species as Edapteryx bilineata {Proc. Ent. Soc. Phil. Vol. 3, Plate 6, Fig. 9.) (9 ) TRANS. AMER. ENT. SOC. JULY, 1868. AUG. R. (iROTE. 86 neata, that the specific distinctions between the two are not very ob¬ vious, though, in the present paper there are regarded as sufficient for the purpose of validating the species. We have seen how closely Platypteryx fubula, Grote, resembles the European Drepana falcataria. The propriety of considering Laspeyres’ Fain. B as a different genus from his Fam. A, is additionally evidenced by its description as dis¬ tinct under the new name of Edupteryx by Dr. Packard, a name which should, however, give way to that of Laspeyres as amended by Stephens. Laspeyres’ third section of Platypteryx, his Fam. C, Leach, iu 1815, erects into a distinct genus under the name of Cilix. which has found universal acceptance. This genus, which contains but a single European species, C. spinula, is unrepresented in the United States. A fourth genus, Dryopteris, Grote (1862), is unre¬ presented in Europe, and falls into a distinct section of the sub-family, differing more strongly from any of the sections of Laspeyres’ genus Platypteryx than do these sections among themselves. It has an Asiatic ally in Greta, Walk., which closely resembles it in ornamentation, but is much stouter. Two species described as North American are not considered valid in the following list of our species. These are Drepana fasciata. Ste¬ phens and Drepana maryinata, Walk. Since Stephens and Haworth wrote, the first is unidentified. It should be recognisable from the character ascribed to its secondaries; “ posterior wings with a single streak,” which will at once separate it from either of our two species of Drepana ; this character is unusual, and reminds us of the Phalaenid genus Drepanodes, Gurnee. The second I have seen in the British Museum. It is a simple variety of Dryopteris rosea. In the Berlin and British Museums are identified specimens of Platypteryx genicula, Grote. All the species here accepted are known to me. No Platyp- terygides appear to be known from California. F a m i ly B 0 M B Y C I D A E . S u bfam i ly P L A T Y P T E R Y G I N A E .

ROBINSON. We have recently enjoyed the opportunity of examining the North American Moths contained in the British Museum Collection and which have been described by Mr. Francis Walker in the “ Lists of the Lepidopterous Insects ” published by that Institution. Bringing with us material for comparison, and aided by the kind attentions of Dr. Gray, Messrs. Walker, Waterhouse and Butler, we have been able to identify many of the species described by Mr. Walker which were previously unknown to American Entomologists except by name and their notoriously insufficient limitation in the work above alluded to. It is perhaps unnecessary to do more than to refer here to the very general condemnation with which scientists have received the ex¬ tended works of Mr. Walker on the Insects contained in the British Museum Collections.* It will be simply sufficient to state that the opinion has been expressed that these works should be ignored, and that the law of priority should be suspended in its operation with regard to these Publications of our Author. It is, however, perhaps, useless to discuss the propriety of a course which it is not likely could be unani¬ mously and strictly adhered to. Since many of Mr. Walker’s des¬ criptions are recognisable and the types are contained in a Public * C. Stal, Notes on the British Museum Catalogue of Homoptera; Journal of Ent.

Museum, the difficulty of carrying out such a measure, to which the future would be fruitful in opponents, must become apparent to re¬ flecting minds. A little consideration will also show that such an ac¬ tion, were it entered upon, would carry with it the stain of an injustice ; and Mr. Walker's very considerable and at times valuable entomologi¬ cal labors be an entire loss toscience. The danger also in establishing such a precedent must not be forgotten. It is true there is a class of descriptions, which are embodied in these “Lists,” which can hardly fail to prove an insurmountable obstruction in the way of the progress of the science for whose furtherance they were mistakenly written, unless their existence be iguored. We refer to those drawn up by Mr. Walker from specimens contained in private Collections in Eng¬ land ; to such typical specimens the student can have access but by acts of extraordinary courtesy on the part of their different possessors, imperfectly described for the greatest part, such types can add but little real value to the Collections in which they are contained, while to prevent these species from. remaining unknown, or at best descending to posterity an unfailing source of unprofitable discussion and litiga¬ tion, it would seem a proper action on the part of the owners of such specimens, were they to deposit the same as a special Collection in the British Museum, so that by actual comparison and examination it may be definitely ascertained what the species are. The principal value of the British Museum “ Lists,” at least so far as those treating of Lepidoptera are concerned, lies in the immense labor which Mr. Walker has bestowed upon the compilation of the synonymy of the previously published species and (if this merit be not counterbalanced by the defective manner in which that material is treated which was regarded by the author as new) in the endeavor to arrange systematically in a single work all the species known to science up to that time and belonging to the Groups and Families therein treated. Uufortunately a comparison of Mr. Walker’s material with his work shows, that we can accept none of his conclusions without verification and that but few can stand such a test. In this way the light which such a work would naturally shed upon the interesting subject of generic representation is entirely lost, since Mr. Walker’s generic determinations are as a rule unreliable in the Moths. It is not that Mr. Walker’s ideas as to generic values can be made a matter of com¬ parative discussion, or that a reasonable latitude is not allowed in a subject which is very far from being one of agreement among natu- AMERICAN LEPIDOPTERA. 69 ralists, but the fact is amply substantiated that no sufficient care or judgment has been exercised by Mr. Walker in this matter. To illus¬ trate : the female of our common Arctia nais (the variety with red secondaries described by Saunders as Arctia decor at a), figures three times as a distinct genus and species, being twice regarded as new to science under the names of Aloa colorata and Apantesis radians. The genus Tanada , of which Mr. Walker remarks that it “ is perhaps as nearly allied to the Lithosiidae as to the Liparidae. and seems to connect the two families,” is founded on one of the Arctiinae, the spe¬ cies ( Tanada antica, Walk..) being nothing more than the common albino form of Euchaetes egle (Drury) Harris , described also by Dr. Fitch as Hyphantria collaris. A second species ( Tanada conscita , Walk..) is subsequently added to the genus, which in its turn is also what may be regarded as an albino form, but one belonging to quite a different genus, the specimen belonging to Callimorpha and being C. vestalis, Pack., which we regard as an immaculate form of C. lecon- tei, Boisd. A third species of this “ genus ” is a white Phalaenid, certainly not belonging to the Bombycidae, apparently not North American and otherwise unknown to us. A rubbed specimen of Thyris maculata, Harris , is described as a new genus and species under the name of Sagalassa perspicua. , while specimens of the same species are erroneously recorded as belonging to Thyris vitrina, Boisd. Thegenusof Halesidota (Halisidota, Hiibner. Ver.) of Mr. Walker contains most dissonant material : Hal. macularia , Walk., is Alpenus aequalis, Walk., and from West Africa; Hal. megapyrrha , Walk., and Hal. chrysogaster , Walk., are identical and both the species now known as Ammalo helops ( Grom.,) though exactly what species is intended by Cramer is not. perhaps ascertained with certainty. On the other hand Ammalo nantana, Walk ., is a Zygaenid. Dryocampa rubicunda, Walk., is recorded from “Brazil,” but this locality is erro¬ neous ; the specimens belong to our common species and were actually collected in the United States. This species is originally described by Fabricius as being found in Virginia. In a “ Supplement’’ Mr. Walker describes a Dryocampa venusta, from the United States and distinctly regards it as a representative of, or nearly allied species to his Brazilian Dry. rubicunda , saying of it: “The rosy costal stripe of the fore wing distinguishes it from D. rubicunda.” Now were there two closely allied species of Dryocampa , one of which the Bombyx rubicunda of Fabricius, found respectively in the United States and Brazils as stated by Mr. Walker, it is evident from an examination of 70 GROTE & ROBINSON. Fabricius’ work that it is the United States species which should retain the name rubicunda , and the Brazilian species receive the new specific name. Relying on Mr. Walker’s generic determination and following out the apparent facts of the case, Mr. Grote has referred the Dry. ncnusta of Mr. Walker as a synonym of Fabricius’ species and proposed for the Dry rubicunda Walk., a necessarily uew name, choosing that of Dry. Walker ii. Upon an examination of the specimens of Dryo- campa venusta, Walk., however, it is seen to be a male individual of Hyparpax aurora (Smith) Hubner ! — the female of which is described afterwards with a wrong locality as Sanya t a rosea ! In the Noctuidae the errors are still more confusing and the diffi¬ cult species are most inadequately described by Mr. Walker. Feltia ducens, Walk., (n. g. et sp.!) is Agrotis subgothica; Mamestra (!) j)la- yiata, Walk., is Noctua bicarnea, Guenee; Xylina (!) contraria, Walk., is Hadena xylinoides, Guenee. The genus Microphysa contains, among others, two species of Epizeuxis, Hiibn. ( Melia , Guenee), one of Anthoecia, Boisd., and another of Drasteria, Hiibn. Perhaps in the whole Family no three more dissimilar genera can be found than these three, species belonging to which are arranged under a fourth but distantly related to them. This same species of Anthoecia (A. rivulosa, Guen.,) is described additionally as Anthophila diver yens and EucKdia (!) desiynata, besides figuring as Microphysa, contractu ! Again Poaphila scissa , Walk., is Panopoda carneicosta, Guenee \ Poa¬ phila amp/issima, Walk., is Parallelia bistriaria, Hiibner ; and Poa¬ phila nanata. Walk., is a species of Drasteria ! The following descriptions of species referred to Hypena by Mr. Walker viz : II. yeneralis , II. rufmalis, II. idaeusal is , II. cacummalis, 11. habitat is. II. sobrialis , H. fa ctissal is, II. caecalis, are to be rejected from that genus and should be entirely ignored, since the specimens upon which they are founded are so defective that the species are irrecognizable and, instead of belonging to the Deltoid or Noctuid genus to which they are referred, they belong to different genera of Crambidae and Tineidae. The limited time which we could devote to our studies in the Bri¬ tish Museum during our stay in England, has prevented our synouy- mical references from being as full as we could have wished. Such as they are, they will, we trust, considerably reduce the number of Mr. Walker’s species over the descriptions of which the student has to pore and expend his time and thought too often in vain. We hope that the attention of those in Authority may be drawn to the AMERICAN LEPIDOPTERA. 71 state in which the British Museum collection of Moths remains at pre¬ sent, and that the necessity which now obliges Naturalists from all parts of the civilized World to personally consult the Collection, in order to ascertain the species intended by Mr. Walker in the British Museum Lists, be obviated by a revision of the material by a compe¬ tent hand.

The B. M. specimens of II. astarte are all males, and were II. varia, Walker, the true 9 of II. astarte, the latter could be readily distinguished from II. obliqua.

This species is congeneric with A. punctistriga, Walk., taken rarely from New York and Pennsylvania to Georgia (apud Walker ) and Texas, but which is not mentioned by Dr. Packard in his Synopsis of IT. S. Bombycidae ( Proc . Ent. Soc. Phil.') ; the genus is allied to Tolype. Artace punctivena, Walk., p. 1492, is founded on a greasy specimen of A. albicans; hence the expressions: “ Tawny, shining, ” used by Mr. Walker in describing the supposed species.

Our United States species is considered now to be distinct from the European. So Deilephila lineata, (Fabr) Harris, is distinct from the European Deilephila li vomica; Fabricius originally described our 76 GROTE & ROBINSON. American species, and afterwards erroneously regarded the European species as the same as his Sphinx lineata , Syst. Ent. (1775). Our species is correctly figured by Abbot ; Cramer figures it (Vol. 2, p. 41 PI. 125 D) as Sphinx daucus. Stephens (l/l. Brit. Ent., Haust. I, 126,) adopts Cramer’s specific name for our species, while his Deile- phila lineata , | 1. c. is not Fabricius’ Sphinx lineata, as above cited, but the European Deilephila livornica. For remarks on these species see Grote, “ Sphingidae of Cuba,” Proc. Ent. Soc. Phil., 1865. Philampelus pandorus, Walk., p. 174 = Philampelus satellitia, J Harris. This is our United States species, and from examination should retain this name since the Sphinx satellitia of Linnaeus, as which it was regarded by Dr. Harris, is now known to be its South American and West Indian ally: Philampelus lycaon of our Synony- mical Catalogue. Drury’s figures are insufficient. Cramer’s S. licaon (PI. 55, fig. A,) is Philampelus satellitia, (Liuu.) Walk. Hubner’s Pholus licaon is a var. of P. satellitia, but not the typical form which wants the roseate anal patch of the secondaries. The material in the Berlin Museum shows the varieties of this species very fully. The Phil, lycaon of Mr. Grote (Sphingidae of Cuba), figure^ in our Syno- njmical Catalogue (Pholus licaon, Hiibn., nec Cram.), should be known as Philampelus satellitia L ., var. posticatus, Grote.

Beneath, the wings are in- AMERICAN LEPIDOPTERA. 81 tense deep orange, the common line followed externally by a bright purplish shade. Both speciesvary in the depth of color but the palest E homuraria is always ferruginous, while E. hypochraria, occasionally so pale as to be of a dirty yellowish grey, never acquires the rusty brown of its ally. The caputal and thoracic scales are more warmly colored in E. homuraria and the fringes of the wings beneath are pur¬ plish. The subterminal clouded shade, which crosses both wings above in E. hypochraria and is more or less distinct, is obsolete in E. homu¬ raria. Expanse 36 mil. Length of body 16 mil.

GROTE, Curator of Entomology, Buffalo Society of Natural Sciences. SPHINX, Linn. Sphinx harrisii ( Ellema harrisii, Clemens). I have seen, in the collection of the British Museum, the specimens determined as Anceryx conifer arum by Mr. Walker in the British Museum Lists (Lep, Ft. viii, p. 224). These are two in number ; the first ($) is a specimen of the European Sphinx pinastri, and seems to have furnished the basis of Mr. Walker’s diagnosis. The second (b) is the true Sphinx coniferarum of Smith as figured by Abbot in the Lepidop. Ins. Ga.” This individual agreed with other specimens from Georgia in the collection of Dr. Boisduval in Paris. Without mate¬ rial of our Northern S. harrisii at hand for comparison, these speci¬ mens seemed to me to constitute a distiuct species, differing apparently in the greater size and the fewer markings of the primaries; thus ap¬ proaching the European Sphinx pinastri closer than does Sphinx har¬ risii. Both forms (assuming them to be distinct between themselves) are to be at once distinguished from Sphinx pinastri, by their imma¬ culate abdomen. However, until specimens of Sphinx coniferarum. Smith, are received from the Southern States and compared with our Northern Sphinx harrisii, the question of the specific validity of the latter cannot be settled. I have also seen an original drawing by Abbot of Sphinx conifera¬ rum, Smith, through the kindness of Dr. Gray. As compared with the British Museum specimen of the species (alluded to above) it en¬ tirely agreed, but when compared with the engraved Plate in Smith’s work it differed slightly in that the markings of the primaries were less prominent ; these had been somewhat exaggerated by the engra¬ ver. "With regard to Sphinx bombycoides (. Lapara bombycoides , Walker), described very briefly in the British Museum Lists from a Canadian specimen in Mr. Saunder’s Collection, I am of opinion that it will prove to be identical with Sphinx harrisii, although the short diagnosis af¬ fords no certainty on the subject. Both S. coniferarum and S. harrisii belongs to Hyloicus Hubner , of which S. (Hyloicus) pinastri of Europe is typical, and which is now 11G AUG. R. GROTE. regarded as a subgeneric division of Sphinx, Linn. (Lethia, Hiibn.) and of which latter genus Sphinx ligustri of Europe is the highest form. The European Spliinx convolvuli on the other hand is regarded as belonging to Macrosila and as the lowest form of a genus well rep¬ resented in America by the more typical species : M. rustica, M. Caro¬ lina, etc. A comparison of our Sphingidae with those of Europe is necessary in order to understand the limit and value of the different genera*. HORAMA, Ilubner. Ho? ama texana {Euchromia plumipes f Clemens ; Callicarus texanus, Grote.). Since describing this species, *{■ I have seen the specimens described by Dr. Clemens | and regarded by him as belonging to the species il¬ lustrated by Drury under the name of Sphinx plumipes §. I find that they belong to Horama, and from their antennal structure are congen¬ eric with Horama pretus, Hiibn , and Horama diffissa, Grote. I am also under the impression that I saw specimens of H. texana in the Brit¬ ish Huseum. erroneously regarded as a variety of H. pretus. SCEPSIS, Walker. Scepsis fulvicollis, Walker. I mention this species in order to record for it a more extended geographical range than has been hitherto allowed by Authors. I have it from Texas, Florida, Georgia, Pennsylvania and New York. The genus is represented in California by S. packardii, Grote. On August the 20th a specimen of S. fulvicollis came to light at Hastings, N. Y. On the 11th of September I took a number of specimens of S. fulvi¬ collis on the flowers of the golden rod (Solidago) near Buffalo, N. Y. It is on this same plant, though not on this alone, that, later on in the year, our common grasshopper (Locusta) ascends to die: and expires clinging to the upper branchlets, to which after death its body still re¬ mains attached. A curious habit and a suggestive. As if escaping from Earth. See on this point Lepidopterological Contributions by myself and Mr. Robin¬ son, Ann. N. Y. Lyc. Yol. viii. 1866; on the third page of this paper, line 23, an error has occured where “Sphinx convolvuli” is printed instead of Sphinx ligus¬ tri.

AMERICAN EEPIDOPTERA. 117 ARCTIA. Schrank. Arctia nais, Hubner ( 9 Bombyx nais Drury; 'J, Arctia phaleratn, Harris.). Those Authors who have distinguished the Arctia phalerata of Har¬ ris from Drury’s Bombyx nais , have overlooked the fact that the for¬ mer is the true male of the latter, and have regarded the sexual as a specific distinction. Hubner committed then no error in his represen¬ tation of the male A. nais (Zutraege Dritt. Hund, fig. 599 — 600) al¬ though, as stated by Dr. Packard with an opposite conclusion, he “fig¬ ures what is unmistakeably A. pliahrata Harris” (Syn. U. S'. Bom- byc. Proc. Ent. Soc. Phil. p. 177, 1864.). Drury’s figure (Vol. l,pl. vii, fig. 3) represents a female with yellow secondaries which may be considered the typical form, though appar¬ ently more rarely occurring than the female with crimson hind wings. This latter may be known as Arctia nais, var. decorata Saunders. It is the Arctia decorata of Mr. Saunders and is also described by Mr. Walker under the names of Apantesis radians and Aloa coloratci. I have seen the specimen in the British Museum under the former name. It is immature, the secondaries dwarfed, and this accidental peculiarity is erroneously regarded by Mr. Walker as normally structural and furnishes the principal character on which he found his genus Apan¬ tesis. Under these circumstances the name proposed by Mr. Saunders may be retained for the variety, although later in date of publication, having on the other hand precedence by priority over Mr. Walker’s Aloa colorata. The male A. nais has the secondaries usually yellow but sometimes tinged with rose color. In either sex the markings of the upper sur¬ face of the primaries are variable. This is especially noticeable in the female, in which sex the yellow bauds and stripes are more or less ob¬ solete, sometimes leaving the wings entirely velvety black with a sin¬ gle abbreviated stripe along the median nervure. What seems to be a variety of the male occurs in which the mark¬ ings of the primaries are very broad and distinct. Arctia complicata, Walker. This species differs from A. dahurica by its paler yellow color. On the upper surface of the primaries, the transverse band is obsolete. Un¬ like its ally, the K-shaped stripes are not obsolete on cell 3. The sec¬ ondaries are more entirely black ; these show pale yellow patches, smaller, differently shaped and more irregular than in A. dahurica. There are black scales on the vertex and two superlateral black spots on the yellow “collar”. The thoracic disc is black, edged with yellow lateral scales. 118 AUG. R. C.ROTE. I have seen Mr. Walker’s type of A. complicata, from Vancouver’s Island, in the British Museum collection and it appears to me to rep¬ resent a valid species previously un described. PHOBETRON. Hubner. Phobstron pitheciu.ni, Packard ( Thymdopteryx ephemeraeformis J Packard). The male specimen spoken of by Dr. Packard in the “Synopsis of the Bombycidae of the United States,” and there determined as Thjri- ( lop ter// x ephemeraeformis, proves to be, as I am subsequently informed by the Author, a male of the present species in which the sexes are quite dissimilar. This circumstance explains the fact that the true Thyridopteryx ephemeraeformis of Stephens is registered in the “Sy¬ nopsis” under the name subsequently proposed for it by Dr. Harris, viz : 0 Hectic us (oeeeticus) conifcrarum. Following out Dr. Packard’s remarks (1. c.), I am led to regard Phobetron nigricans ( Thyridop . nigricans , Pack. 1. c.) as a distinct form, although I have as yet seen no specimens of this second species of the genus. ADONETA. Clemens. Adoneta spinuloides (Limnacodes spin. H-S. ; Adoneta voluta, Clemens ; Ci/clop- teryx || spin. Pack.). An examination of the types of Dr. Clemen’s Adoneta voluta , now in the possession of the American Entomological Society, enables me to refer the species as identical with one previously illustrated by Dr. Herrich-Schaeffer. The generic term employed by Dr. Packard in the “Synapsis” had also been previously used by Gfueneo. The typical specimen of Adoneta leuco.sigma ( Cjclopten/x || leucos. Pack,) is also contained in the collection of the Entomological Society. It is a male and as yet the sole representative of the species that I have seen. TELEA, Hubner. Telea montezuma ( Saturnia montezuma Salle). This species from Mexico, which I have seen in the Museum at the Jardin des Plantes in Paris, resembles our United States Telea poly- phemus quite closely, but is at once distinguished and characterized by the uneven external margin of the wings. ACRONYCTA, Ochsen. Aeronycta vinnula ( Microcoelia vinnula Grote). I here correct my original generic reference of this species which is easily recognized by the olivaceous shading of the upper surface of the primaries and its small compact form. It is as yet rare in collections. AMERICAN LEPIDOPTERA. 119 DERRIMA, Walker. Derrima henrietta ( Philomma Henrietta Grote). I have seen in the British Museum Collection the type of Derrima stellata, Walker. It is a female and closely resembles P. henrietta with which it is congeneric. Mr. Walker places the genus as belong¬ ing to the group of genera regarded as a Family under the name of Acontidae. I am still of the opinion that the genus is allied to Anthoe- eia and Heliothis. The squamation is rough and lustreless, not smooth and lustrous as in Tarache {Acontui) and its allies. From D. henrietta, of which I have a very numerous series of both sexes, Mr. Walker’s I), stellata differs as follows : the fringes on both wings are long and pink ; the secondaries above and both wings beneath are suffused with pink ; the ocellate spots on the primaries above are a little larger, pure white narrowly margined with black scales, not with suffused ferrugin¬ ous borders (in which the lower spot is generally absorbed) as in D. henrietta; the pink terminal space of the same wings is shaded with yellow and the ground color of both wings beneath is yellow shaded with pink on the borders; finally the narrow line, which defines the pink terminal space inwardly, appears to be straight, not scalloped and defined by white dots as in D. henrietta. I have placed a specimen of D. henrietta in the British Museum Collection. CALLEDAPTERYX (n. g. Phalaenidae). Head small; eyes globose and large; antennae short, simple, rather stout and closely scaled. Labial palpi slight, divaricate, passing beyond the front. Legs stout, smoothly scaled ; hind tibiae with two pair of stout spurs, lower pair half the length of the tarsi. Wings with scalloped margin. Primaries with the costa rising and slightly arched to the rounded apices ; below these the external mar¬ gin is deeply and evenly semi-circularly cut out to extremity of first median nervule, below which point the margin retires straightly and evenly inwardly obliquely to the exerted internal angle. Internal mar¬ gin very sinuate, retiring inwardly behind the angle. Neuration : Costal nervure simple ; subcostal nervure throwing off from its upper side the first, second and third s. c. nervules on the margin, from a point at about the middle of the wing : these nervules approximate and equi¬ distant at base, 1 and 2 simple, 3 shortly furcate just before the mar¬ gin ; fourth and fifth s. c. nervules thrown off together at the extremity of the nervure ; fourth, furcate before the apex of the wing, the sixth is simple, joining the external margin at the subapical excavation; a 120 AUG. R. GROTE. diseal fold ; the cell is open ; median nervuve three branched, first and second m. nervules thrown off together at the extremity of the nervure; third, more remote; a submedian fold; internal nervure simple. Sec¬ ondaries with the costal edge roundedly exerted at base, the costal ner- vuse here bent upwardly and the tegument extended beyond it. The real apices of the wing are rounded and comparatively retired, but the external margin is pointedly projected beyond and below them at the extremity of the subcostal nervure or its upper branch or first nervule. Below this the external margin is slightly excavate to extremity of the lower branch or second s. c. nervule. Below this again the margin is more widely excavate, rising to the extremity of the first median nervule which is exerted to a point on a line with the extremity of the first s. c. nervule. Beyond this the margin is even to internal angle. This genus is founded to receive a pretty little Phalaenid with beau¬ tifully cut wings, apparently allied to Drepanodes Guenee and Timandra Walker. When at rest the primaries are spread out horizontally, but the secondaries are depended, the internal margin folded over the ab¬ domen ; thus a wide space is left between the anterior and posterior wings. Calledapteryx dryopterata, n. s. Entirely pale ochreous, sometimes entirely of a pale wood brown. Two transverse, dark, somewhat olivaceous lines cross the primaries at the middle; these are subparallel, outwardly angulated, narrow, and appear somewhat as the margins of an obsolete mesial band, being shaded and the space between them partly filled in with dark irrorations on the internal margin where the inner line is marked with two blackish or darker disconnected spots. The outer line is obsolete below the dis- cal fold. A faint semicircular dark line before the subapical excava¬ tion on external margiu. Fringes short, blackish. Secondaries resem¬ bling primaries. The two median lines are continued, more distinct and medially outwardly angulated and appear also to be obsoletely gemi¬ nate with a paler included shade, the short fringes blackish. Beneath paler than above, immaculate, very sparsely and coarsely mixed with dark scales, or irrorate. Body and appendages concolorous with the wings, immaculate. Expanse, — 20 m.m. Length of bod//, 5 m.m. Habitat. — Atlantic District (X. Y., Penua.). Imago flies in July and August. AMERICAN LEP1D0PTERA. 121 TORTRIX, Linn. Tortrix rileyana, n. s. 9 . Deep ochreous. Primaries evenly washed with purplish, leaving the fringes and costal edge dark ochreous. The markings take the shape of dark velvety brown rounded maculations, generally of small size and faintly shaded with ochreous on the edges. Three of these subterminally at the base of the wing, subequal, situated interspaceally between the nervnres. At a little within the middle of the costa are two fused maculations, the most prominent. Before and beyond these, some faint costal marks. At the extremity of the discal cell, above me¬ dian nervure, is the first of a series of maculations, normally four in number but not constant, usually uneven in size. A subterminal series of spots is inaugurated on costa by a large compound shaded maculation. Below this, over the median nervules, sweeps an outwardly rounded series of small approximate dots. Two dots on costa, within and at the apex, and a faint terminal series of minute streaks is shortly discontinued. Secondaries of a lustrous bright deep ochreous; pale along costal margin and darker shaded along internal margin. Be¬ neath, as are the secondaries above ; both wings immaculate, primaries the darker. Body and appendages concolorous, bright deep ochreous. Antennae simple. Expanse , 28 m.m. Length of body , 10 rn.rn. “No 234, Larva on Hickory”. Two specimens. $ . Much smaller than the above, of a paler color. The upper sur¬ face of primaries not washed with purplish but merely of a darker ochreous than the secondaries. The maculations entirely similar but ferruginous, paler than in the 9 and the slighter costal marks are ob¬ solete. Abdomen with a moderate anal tuft. Legs at base and under thoracic surface almost whitish. Expanse , 20 m.m. Length of body , 6 m.m. “No. 234. Larva on Symphoricarpus.” Two specimens. Four specimens received from Mr. C. V. Riley, to whom I take pleasure in dedicating the species. Whether the differences noted above are sexual (which I incline to believe) or variations concomitant with the different food plants, I am unable to say and have not sufficient material to decide. The two male specimens agree with each other as do the two of the opposite sex. Belongs to Tortrix Linn., as more recently defined by Lederer and Heineman. TRANS. AMER. ENT. SOC. (16) AUGUST, 1868. ] 22 W M . II. EDWARDS. The costa of primaries is rounded from the base outwardly towards the apes, before which it is depressed, the apes rising, acuminate. The external margin recedes immediately below the apices, and is thence outwardly rounded, hardly oblique. The full secondaries are hardly produced at the apical angles. The neuration is typical and normal. The labial palpi are advanced beyond the front ; third joint small, conical, scaled ; middle tibiae with a single, the thicker hind tibiae with two pair of spurs.

Cope, comprises all those collected by him and Prof. Leidy dur¬ ing an extended Geological exploration of the mountainous regions of several of the South-western Counties of Virginia. The object of the trip being one of some importance to Geological Science, the time de¬ voted to Entomology was of necessity quite limited and the results con¬ sequently not large, sufficient it is hoped, to remind others while simi¬ larly exploring of what may be attained by a small occupation of lei¬ sure and the great gain to our knowledge of distribution by the aggre¬ gation of small collections from different regions of the country. The opportunity now afforded will he made use of and several other interesting species described or noted, from regions not remote, though in neighboring States.

In Eu¬ rope, specimens are found, not very commonly however, under stones, in the soil or in the shell of dead Helices. Two specimens of this species from our owu country have come under my observation, one, in the collection of Mr. Ulke of Washington, was found in the mountain¬ ous region of Eastern Tennessee, by Mr. Fuchs, a gentleman to whom science is iudebted for many interesting discoveries, another of which will be described in the present paper. For the other specimen I am indebted to Johnson Petit, Esq., of (xrimsby, C. W. I have no account of its habits. ANOPHTHALMUS Sturm, A. pusio. pale brownisli-testaceus; head oval, slightly longer than broad, lon¬ gitudinal impression faint, surface very finely alutaceous; thorax trapezoidal, slightly broader than long, feebly emarginate anteriorly, sides moderately round¬ ed anteriorly, slightly sinuate posteriorly, base feebly bisinuate, and emargi¬ nate at middle, surface smooth, shining, with median longitudinal line and a broad impression within each hind angle, angles rectangular; elytra oval, sides moderately rounded, humeri distinct, obtuse, surface feebly striate and sparsely covered with suberect very short pubescence. Length .15 inch. This species may be readily distinguished from any of our others by the form of thorax as well as by the pubescence covering the elytra and under surface of the body. The thorax is slightly broader than long, trapezoidal, narrower behind. The surface is less convex than any of the described species of our country, not only that of the thorax, but also of the elytra. The humeral angles of the elytra are well de¬ fined, and the bases of the elytra nearly transverse and not obliquely produced as in TdlkampjU. The head is relatively broader than in the 126 GEO. II. HORN, M. D. glabrous species, and the thorax scarcely broader than the head. In this species the mentum tooth becomes very broad and obtuse, approach¬ ing in this respect Aphsenops, in which the mentuiu has no tooth. The upper surface of the body is provided with setae, arising from punctures, those on the head being short ; the thorax has one on each side about its middle, the elytra have three each, arranged in a row, one near the base, another median, and a third near the apex. Science is indebted to E. D. Cope for this interesting addition to our fauna (being our smallest species) collected in Erhart’s cave, Mont¬ gomery County, Virginia. A. pubescens, pale testaceous, shining, head oval, attenuate anteriorly, finely alutaceous, and with two longitudinal, faintly impressed lines convex intern¬ ally. Thorax moderately convex,, glabrous, one-third broader than long, tra¬ pezoidal, narrower behind, sides broadly rounded, sinuate posteriorly, angles acute and prominent, a longitudinal median line and two basal impressions, anteriorly feebly emarginate, base slightly produced and emarginate at mid¬ dle. Elytra oval, moderately convex, with striae evanescent at the sides and apex, base broadly rounded, humeri distinct, obtuse, surface clothed with ra¬ ther dense sub-erect pubescence, third stria with three setigerous punctures. Be¬ neath finely and more sparsely pubescent. Length .23 inch. Easily known by its pubescence, form of thorax, and very acute hind angles. The form of thorax is very nearly that of TrecJius ru- be7is. The pubescence covering the surface of the body is exceedingly fine in this and the preceding species, requiring a good lens for its detection. Collected in Cave City cave, by Mr. Chas. Sonne. A single speci¬ men in the cabinet of I)r. LeConte. Some of the European Anophthalmi are said to be provided with eyes. Among the specimens I have been able to examine, none of ours have that reticulation and peculiar clearness of the side of the head thought to be an evidence of the presence of an organ of vision. The species in which the eyes (?) occur are not found in caves but under stones on the surface of the ground, and generally in dense damp forests. In our collections, four species of Anophthalmus are found. For the convenience of students I append a table. Glabrous species. Humeral angles of thorax obliquely rounded. Thorax much longer than broad, angles rectangular . ...Telkampfiii. Thorax slightly longer than broad, angles acute . . Menetriesii. Pubescent species. Humeral angles obtuse.

Menetriesii Motsch.= angnlatw Lee. — The glabrous an pu¬ bescent species differ also from eich other in the greater prolongation of the base of the elytra in the former, as well as by their greater elon¬ gation of form. ANILLTJS Duval. A. fortis. testaceous, shining, sparsely covered with short pubescence, head very finely alutaceous and with a shallow longitudinal impression each side. Thorax trapezoidal, moderately convex, shining, and with a single setigerous puncture on each side, narrower behind, sides rounded, anteriorly feebly ernar- ginate, base squarely truncate, angles rectangular ; a slight median and well- defined transverse line, convex anteriorly, in front of basal margin. Elytra oval, moderately convex, surface very finely alutaceous, and with rows of rather coarse punctures, evanescent toward the apex, and on the sides ; sides broadly rounded, humeri distinct, obtuse. Legs testaceous, finely pubescent. Length .08 inch. In addition to the very fine pubescence sparsely scattered over nearly the whole body, the elytra have also long setae arising from larger punc¬ tures, apparently placed in a manner similar to that seen in the species of Aphsenop: s of Europe. As compared with debilis , this species is of larger size, more robust form, the thorax broader and less narrowed be¬ hind and more convex. The pubescence and sculpture of elytra are also important points of difference. For my specimen of this species, I am indebted to Mr. Ulke. The specimens were collected by Mr. Fuchs in the mountainous regions of Eastern Tennessee. «. ATINUS, n. gen. I suggest this name for a genus of Pselaphidae founded on the spe¬ cies described by Dr. Brendel in the Proc. Eat. Soc. Phil. , under the name of Ctenistes monilicornis. It differs from our other Pselaphidae by the excessively short palpi. The labial palpi appear to be two-joint¬ ed, cylindrical, the last joint nearly twice longer than the first. The maxillary palpi are four-jointed, the first two short and cylindrical, the second being much narrower than the first at the junction, the last two are globular, the terminal joint being very much the larger and with a few setae on its surface. Antennae are about half the length of the insect, stout. Joint 1 cylindrical, equalling 2 and 3 ; 2 — 3 cylindrical, 4 — 8 globular, gradually shortening; 9 — 11 slightly broader and more cylindrical than the preceding, the last joint equalling the two pro¬ ceeding in length. 128 GEO. H. HORN, M. D. Whatever may be the affinities of this insect, it certainly is not a Ctenistes, while it appears to replace in our own fauna the Chennium or Centrotoma of the old world. There are no semblances of appendages such as are seen on the outer edges of the palpi of genera near Cte¬ nistes anA Centrotoma, nor is there any stout seta such as is found on the last joint of the palpus of Tt/rus. In the present genus the palpi are so short as scarcely to exceed the mentum in length, and are conse¬ quently very difficult to define without dissection, a matter of no great ease in a Pselaphide. It is to be desired that sufficient specimens may be found to warrant the sacrifice of some of them. Atinus monilicornis. Ctenistes monilicornis, Brendel, Proc. Ent. Soc. Phil. 1806, p. 190. Collected by Mr. Fuchs in the mountainous region of East Tennes¬ see. Fustiger Fuchsii, Brendel (loc. cit.) — Dr. Brendel seems willing to accord two ocelli to this insect, each containing three facets. Sev¬ eral specimens in my cabinet, and that of Dr. LeConte have failed to show any such structure even under the power of a quarter-inch ob¬ jective. Dr. Brendel has without doubt been deceived by reflected light from prominent points of sculpture. AMERICAN COLEOrTERA. 129 New species of COLEOPTERA from the Pacific District of the United States. BY GEO. H. HORN, M. D. OMUS Eseh. O. submetallicus, aeneous black, shining, elongate. Head rather coarsely alutaceous, very sparsely punctured between the eyes. Thorax trapezoidal slightly broader than long, sides moderately rounded, narrower behind, margin not acute; anterior margin truncate, posterior sinuate, angles obtuse, surface coarsely alutaceous. Elytra elongate oval, broader behind the middle, margin very acute and slightly reflexed toward the humeri, surface coarsely but not densely punctured with a few large punctures irregularly placed along the mid¬ dle of each elytron. Tibise and epipleuree brownish-ferruginous. Length .58,^, . California. A single specimen in the Cabinet of Mr. H. Ulke. A very singular species, differing from all our others by its more elongate and cylindrical form as well as by its color. The elytra are not regularly oval as in our other species. The sides in front of the widest portion being nearly straight and gradually convergent. In form of thorax it more nearly resembles Auclouinii with the margin much less acute. The elytral margin on the other hand is more acute than in any other of our species and very distinctly reflexed towards the humeri. This is now the fifth species of the genus and should be placed between Audoumii and Isevis. PACHYTELES Ferty. P. testaceus, dark testaceous, both above and beneath. Head elongate-oval, surface very finely alutaceous and with a few large punctures at the sides in front of the eyes and within the insertion of the antennae, middle of front between labrum smoother. Labrum slightly emarginate. Eyes moderately prominent. Thorax trapezoidal, broader than long, narrower posteriorly, trun¬ cate before and behind, angles nearly rectangular, sides moderately rounded anteriorly, sinuate and slightly reflexed; surface moderately convex, nearly smooth and with a longitudinal impressed line. Elytra slightly broader than the thorax, parallel, slightly longer than twice their width, apex broadly round¬ ed, base feebly emarginate, surface faintly striato-punctate, punctures very fine and obsolete on the sides and apex. Beneath smooth, scarcely jmnctured. Length .16 — .20 inch. Besides the characters above given it may be seen that the thorax is slightly broader than the head and much more smooth than either head or elytra. The margin is very distinct and broadest near the basal an¬ gles and somewhat narrower at the middle of the side than at the an¬ terior angles. The whole surface is very sparsely clothed with very short erect pubescence arising from scarcely evident punctures. The TRANS. AMER. ENT. SOC. (17) AUGUST, 186S. 130 GEO. II. HORN, M. D. legs are more densely pubescent. The anterior femora are armed near the middle with a tooth more acute in the male than female. I have in my possession also a specimen considered as being vertica- lis Chaud., from the description and the locality from whence it was de¬ rived. Excepting in color testaceus appears to differ very slightly from either this or Gyllenhalii. As compared with vertically the head is more elongate and less punctured, the thorax rather less convex and the median impressed line rather more evident, the hind angles are also less acute. The elytra are more nearly parallel and much less shining. This species is rare, a very small series was captured by myself at Fort Grant. Arizona. PanagtEUS Sallei Chaud., must now be considered an inhabitant of our territories, numerous specimens of this and our eastern fascia- tus Say were collected by me in the region with the Pad ly teles above described. TETRAGON ODERUS Dej. T. pallidus, testaeeousxsubopaque. Head and thorax very finely granulate. Thorax trapezoidal, broader than long, narrower behind, feebly emarginate at apex, truncate at base ; sides rounded in front, straight and gradually conver¬ gent behind, hind angles obtuse. Elytra faintly striate, interstices flat, very finely alutaceous. Beneath smooth, impunctured. Length .22 inch. From Southern California (Temescal) and Arizona (rare). Differs from our other species in color, and almost total absence of any marked sculpture. The form of thorax is similar to fasciatus. ANISODACTYLUS Dej. Dichirus Mann. A. strenuus, oblong, moderately convex, dark brown, clothed with erect, short, yellowish hairs. Head coarsely punctured. Thorax very sparsely punctured, convex, shining, slightly wider than long, narrower behind, sides broadly rounded, gradually narrowing, anterior angles rounded, apex feebly emarginate base truncate, angles obtuse. Elytra striate, striae not punctured, interstices moderately convex irregularly biseriately punctulate. Femora strongly dila¬ ted, the anterior very robust. Length .60 inch. Two specimens from Fort Tejon, California. This is much larger and mere robust than any of our species yet described. As compared with hirsutus, it is more convex and robust, with the thorax less densely punctured, less narrowed behind and less emarginate in front. The thighs are also very robust, those of the an- erior pair especially so. AMERICAN COLEORTERA. 131 EUTHEIA Steph. E. colon, testaceous, shining, sparsely clothed with suberect yellow hairs, head scarcely punctured, thorax quadrate, moderately convex, sides rounded in front, gradually narrowing behind, hind angles distinct, base truncate, with transverse row of six large punctures. Elytra moderately convex coarsely punctured, pubescent, and with two black spots at the posterior third. Length .04 inch. One specimen from Fort Grant, Arizona. The elytra are of a paler color than the rest of the body, and more densely pubescent. This species is abundantly distinct from that de¬ scribed by Mannerheim from Alaska. Another species has been found by Mr. Ulke in the Middle States. It is likewise very rare, and I have had no opportunity of studying specimens or of comparing them with this one. TRIARTHRON Mserkel. T. Lecontei, elongate oval, testaceous, shining, very sparsely clothed with very minute erect hairs. Head very finely and sparsely punctured. Thorax transverse, twice as broad as long, convex, sparsely and finely punctured, trun¬ cate in front, feebly rounded at base, sides feebly rounded and very faintly margined, basal margin distinct and with a transverse row of coarse punctures. Elytra with striae of very coarse, closely placed punctures, interstices flat, faintly biseriately punctured and finely rugose. Length .12 inch, . A single specimen from the high South-eastern Sierras of California. I have had no opportunity of comparing it with the European species. Triarihron differs from Hydnobius in having the antennal club 3- jointed. XANTHOPYGUS Kraatz. X. cacti, black, shining. Head with vertex smooth, sides and near hind an¬ gles coarsely punctured, thorax as broad as long, middle of disc smooth, on each side a row of coarse punctures, and with coarse punctures towards the margin ; sides feebly, base broadly rounded, hind angles not evident, apex trun¬ cate, angles distinct. Elytra bluish-black, coarsely and densely punctured and clothed with black sub-erect hairs; abdomen black, last two segments yellow, finely but sparsely acieulately punctured. Beneath black finely punctured and with the legs irregularly clothed with hairs. Legs black. Length .64 inch. Fort Grant, Arizona. Under decomposing Cereus ; rare. This genus of Staphylini is now for the first time indicated in our fauna. The elytra of this species are rather densely hairy. The head and thorax are also provided with a few hairs, arising from the large punc¬ tures scattered irregularly over their surfaces. To what foreign spe¬ cies it is allied, I cannot indicate. 132 GEO. H. HORN, M. D. SPHiERIUS Waltl, S. politus, black, polished, entirely smooth, nearly hemispherical. Thorax broader than long, narrower in front, sides feebly rounded. Beneath smooth, polished ; femora paler. Length .03 inch. Visalia, California. Mr. W. M. Gabb. This insect is another of the interesting discoveries made by Mr. Gabb and is, with the exception of a few Trichopterygidae, the small¬ est insect ever collected in that prolific State. It adds an entirely new form to our fauna, aud in accordance with the usual distribution of genera, leads us to expect a species from the eastern region. Its habits are probably similar to the European species, as specimens of Georys- sus (n. sp.) were abundant in the same small collection in which it oc¬ curred, as also other riparial insects — Psammodim and Syncnlypta. This insect appears to agree perfectly with the genus to which it is refered, but is nearly double the length of the other species. OTHNIUS Lee. The species of this genus have already amounted to four in our col¬ lections, of which two are as yet undescribed; another has been indica¬ ted and a provisional name given it, but as no specimens exist, it is decidedly better to drop the name from our catalogues until specimens are found from which descriptions can be made. The following table exhibits the relations of the species: Antennae and legs brown or black ; thorax very densely and coarsely punctured. Elytra clouded . umbrosus Lee. Elytra uniform in color, dark bronze . lugubris Horn. Antennae and legs pale or testaceous; thorax sparsely punctured. Short. Elytra banded with yellow . fasciatus Bland. Elongate. Elytra indistinctly banded . mexicanus Horn. 0. umbrosus Lee. Class. Col. N. A. 103. This is the most elongate of our species. The head and thorax rather densely and coarsely punctured. Elytra coarsely punctured, somewhat paler in color than the head and thorax, irregularly clouded with a still paler color, and clothed with whitish hairs irregularly placed. The marginal line of the thorax is not evident at the anterior third of the margin. 0. lugubris, dark black bronze, uniform in color, head very coarsely and densely punctured. Thorax densely and coarsely punctured, subquadrate, slightly narrowed behind and with two indistinct teeth. Elytra elongate, twice as long as wide, sides subparallel, coarsely and densely punctured, and sparsely clothed with whitish hairs. Beneath black, shining, thorax and pec¬ tus coarsely but not densely punctured ; abdomen finely and not densely punc¬ tured, and sparsely clothed with whitish hairs. Legs black, knees and tarsi paler. Length .20 inch. AMERICAN COLEOPTERA. 133 Distinct from umbrosus by its less elongate form and the uniform color of elytra. The obtuse teeth of the margin are more distinct and the punctures of the surface of the thorax are less dense and never confluent. This species was collected by Mr. Win. M. Gfabb in South-eastern Oregon. w i 0. fasciatus Bland, Proc. Ent. Soc. 1S64, 253. The collection of the Society contains two specimens of this pretty species. The thorax is teneous, feebly punctured. Elytra elongate oval, and ornamented with yellow in the following manner : a large irregular spot at base enclosing a small black spot on basal margin of elytra, near the middle of each elytron ; at> irregular band behind the middle, broadest at suture and not reaching the margin; a round sub- apical spot close to the suture, and the apex also paler. Legs and an¬ tennae yellow. Length .15 inch. 0. mexicanus, elongate, head and thorax seneous, coarsely but not densely punctured. Thorax subquadrate, hind angles distinct. Elytra elongate oval, coarsely but not densely punctured, brownish ornamented with paler bands and sparsely clothed with suberect whitish hairs. Body beneath paler, coarsely and sparsely punctured. Legs and antennae yellowish. Length .19 inch. The elytra! ornamentation is similar to the preceding species, and is as follows : an oval basal spot enclosing a small black spot near its apex, and at the basal margin of the elytra, and an irregular transverse baud behind the middle, very broad at the suture, narrowing rapidly and not extending to the margin. From Mexico. Collection of Dr. LeConte. Differs from all our species in its elongate form, and being more attenuate behind. The elytra are also much smoother and scarcely punctured near the sides and apex. GYASCUTUS Lee. G. cuneatus, elongate, cuueate, aeneous-green, shining, epistoine truncate, head intricato-rugose, thorax slightly broader than long, narrowed in front sides nearly straight, truncate in front, trisinuate at base, hind angles acute, not divergent, coarsely, and at the sides confluently punctured. Elytra narrow, convex, gradually narrowing from base, apex bidentate, rather coarsely and ir¬ regularly striato-punctate. Beneath finely and densely punctured. Hind tar¬ sus as long as tibia, compressed, first joint equalling the two following. Length .75 inch. One specimen from Owen’s Valley, California. Collected by Dr. H. M. Cronkhite, with many other specimens of G. obliteralus. Differs from our other species in its cuueate form, and by its tarsal characters. Its color beneath is paler, the prosternum polished and violet colored. 134 GEO. H. HORN, M. D. The antennae are rather longer than our other species, exceeding in length the head and thorax by nearly one-half. Gr. obliterate! s Lee. — Numerous specimens of this species were found in Owen’s Valley by Dr. Cronkhite and myself on willows, they do not appear to differ specifically from those found by Gen. Pope in Texas. For convenience, I add a table of our species of the genus. Hind tarsi with first joint equalling joints 3 and 4 together. Epistome broadly eraarginate. Elytra obliquely grooved . planicosta Lee. Elytra striato-punctate, rugose . obliteratus Lee. Epistome truncate. Thorax not rounded on the sides . cuneatus Horn. Hind tarsi with first joint slightly longer than second. Epistome deeply emarginate . sphenicus Lee. Epistome broadly emarginate . caelatus Lee. The first three species have the hind tarsi not only long but also compressed, while the last two have robust, rather flattened tarsi. G. cuneatus appears to combine the form of the second group with the peculiar tarsal characters of the first with the form of epistome pecu¬ liar to itself. CYMATODERA Gray. C. californica, elongate, dark castaneous, shining. Head finely and rather densely punctured, thorax cylindrical, twice longer than broad, slightly nar¬ rower behind, slightly constricted in front and behind the middle, surface feebly punctured and very sparsely clothed with yellowish hairs. Elytra elon¬ gate, subparallel, three times longer than broad at base, base truncate, humeri distinct, obtuse, apex sinuate, with suture toothed, surface with stride of coarse punctures, becoming obsolete towards the apex, sparsely clothed, with very short suberect hairs, and with an indistinct pale transverse narrow fascia at middle. Surface beneath and legs ferruginous. Length .76 inch. For this insect, as well as others that have been and others that will hereafter be described. I am indebted to my friend Mr. Wm.M. Gabb, by whom this insect was collected in the southern Coast Range of Cal.f >rnia. This is the largest species of the genus in our fauna. Its thorax is more nearly cylindrical and much less narrowed behind than any other of our species, and the sides of elytra more nearly parallel. The pale fascia is nearly straight, not undulate, and continuous. The api¬ ces of the elytra are sinuate and prolonged at the suture. AULICUS Spin. A. nero Spin. Clerit. I, p. 331, pi. 5S, fig. 1. I quote this species merely to note its addition to our fauna, speci¬ mens having been collected by Mr. Gabb in the southern Coast Range of California. AMERICAN COLEOPTERA. 135 ENOPLIUM Latr. E. humerale, black, opaque, head black, finely and densely punctured ; thorax black, broadly margined with yellow, slightly broader than long, shining, rather finely and densely punctured, anteriorly truncate, sides and base rounded, the latter slightly margined at middle, hind angles scarcely evident; elytra rather depressed, obovate, truncate at base, finely granulated, and with an elongated triangular humeral spot, yellow; beneath black, scarcely punctured, legs black, hairy; antennae ten- jointed, tarsal claws slightly dilated at base. Length .21 inch. One mutilated specimen from New Mexico. Similar in form to our 4- punctatum . The thorax is black with rather a broad margin of yellow on each side. The yellow humeral spot is triangular and includes all that portion of the elytra outside of a line drawn from near the scutellum to a point slightly behind the middle of the lateral margin. The inner margin of the spots is not straight but sinuous. IIYDNOCERA Newm. H. robusta, black, faintly bronzed, robust, head coarsely and densely punc¬ tured, thorax as long as broad, narrower behind, constricted in front, sides rounded, densely and coarsely punctured, and with the elytra and head sparsely clothed with rather long whitish hairs. Elytra shorter than abdomen, very convex, narrowing behind, very densely and coarsely punctured, and with two l&rge yellow spots on each, the first basal, quadrate, and touching the suture, the second cordate and behind the middle. Legs yellowish, hind pair darker, nearly black except at base. Body beneath seneous-black, finely punctured and sparsely clothed with white hairs. Length .25 inch. From Owen’s Valley, California. One specimen. Easily distinguishable from any of our robust species by the char¬ acters above given. ACREPIS Lee. A. 4-signata, dark aeneous, shining, sparsely clothed with cinereous hairs; head and thorax each globose, thorax narrower behind, truncate and slightly margined, moderately densely punctured; elytra bluish-green, subcylindrical, parallel, broader than the thorax, roughly punctured, each elytron with two reddish spots, the first round and humeral, the second crescentic, subapical. Length .30 inch. Collected uear San Francisco, Cal. Cabinet of Mr. H. Ulke. The occurrence of this species enables us to pronounce on the va¬ lidity of the genus. It appears to be abundantly distinct from all the others genera of Psoini. In addition to the characters given by its author, the following may serve to render the description fuller : — Head free. Antennas ten-jointed, longer than head and thorax, first joint thick, cylindrical, second short, rounded, as broad as first, joints 3 — 7 short, equal, narrower than the second, last three joints broader, flattened, forming a loose club, of which the first two joints are broadly oval, the last more elon¬ gate, flattened and emarginate in front near the tip. Anterior coxae not con- 136 GEO. II. HORN, M. D. tiguous. Tarsi longer than the tibiae, first joint very small, very indistinct, apparently four-jointed. CONONOTUS Lee. C. macer, elongate, testaceous, densely covered with greyish pubescence. Head coarsely punctured, thorax obconieal, convex, one-half broader in front than behind, sides feebly rounded in front, surface coarsely punctured, more densely in the middle and towards the base. Elytra elongate oval, convex, with striae of coarse punctures, becoming obsolete towards the apex. Length .14 — .16 inch. Not rare in Owen’s Valley, California. Under stones. This species differ from serieans in the form of the thorax and the sculpture of the elytra. In the latter species the thorax is much broad¬ er in front, being therefore nearly as broad as long, and twice as broad in front as at base. The thorax is also flattened above, very evenly punctured and much less densely pubescent. From punctatus it dif¬ fers in size, and the proportions of thorax; in this species the thorax is more robust, shorter and more convex, less broad (relatively to the base) in front, and with the sides rather more strongly rounded. The surface is also less densely pubescent, and with the hairs more erect. They may be distinguished by the following table : Elytra confusely punctured. Thorax very broad in front, depressed above, .13 — .15 inch. ...serieans Lee. Elytra with striae of large punctures. Surface densely clothed with pubescence, .14 — .16 inch . macer Horn. Surface sparsely clothed with pubescence, .06 inch . punctatus Lee. MYCTERUS Clairv. M. flavipennis, black, opaque, elytra orange-yellow; head and thorax black, opaque, very densely and rather coarsely punctured, thorax broader behind, not longer than broad, sides behind the middle nearly straight, anteriorly rounded. Elytra oval, coarsely and moderately densely punctured, and sparsely clothed with short recumbent silken pubescence. Beneath black, densely and coarsely punctured, abdomen more finely and less densely punctured, and sparsely covered with a whitish, silken pubescence. Legs, antennae and palpi nearly black, Length .25 inch. Collected by Wm. 31. Gabb in Oregon. A single 9 specimen. Head entirely black, parts of mouth (except palpi) paler; antennae dark, nearly black ; thorax opaque-black ; elytra orange-yellow ; body beneath black ; legs dark almost black. Our species, of which this is the third, appear scarcely to differ in form and hardly in size, and it is consequently only on difference of color or characters in the antennae of £ , that specific distinctions must be founded. The form of antenna of the £ is without doubt the cha¬ racter of greatest value in separating the species. It is not possible to assign a place by means of it to flavipennis, one £ only being known. Our three species thus differ : AMERICAN COLEOPTERA. 137 Elytra black. Antennas and part of epistome yellow. Third joint of antennae 'J, , broadly triangular, succeeding joints strongly transverse, almost pectinate. Legs all yellow . scaber Hald. Third joint of antennae % , nearly cylindrical, slightly compressed, succeeding joints longer than broad. Hind legs, or at least femora black . . concolor Lee. Elytra yellow. Antennas, whole of palpi, and front, dark.... flavipennis Horn. Our species of Mycterus are found eacli within a very distinct fau¬ nal region ; scaber being eastern, concolor to that central region of the extreme west, bounded on the west by the Sierra Nevada range, while flavipennis is essentially a west coast insect. The characters given in the preceding table will enable them to be recognized when found. M. concolor Lee. occurs abundantly at Keyesville, Cal., and may be fouud ou the flowers of the Aesculus (Buckeye). MECYNCTARSUS Ferte. M. delicatulus, testaceous, moderately elongate, clothed with whitish silken pubescence. Thorax broader than long, narrower behind, sides broadly rounded, posterior angles scarcely distinct, horn elongate, margin very coarsely dentate, crest distant from margin, narrow and serrate in front, and with a longitudi¬ nal fine ridge. Elytra oval, humeri broadly rounded, suture and common cen¬ tral spot dark brown or black. Length .10 inch (horn included). Two specimens from Fort Yuma, collected by Capt. Jno. E. Hill. The horn is about two-thirds the length of the thorax, its margin very coarsely dentate. The crest occupies the middle third of the horn, and is itself finely serrate, and encloses a fine longitudinal ridge. Be¬ tween the crest and the margin of the horn, in front, are some shining granular elevations. Mecynotarsus differs from Notoxus in having the hind tarsi longer the tibiae, and the penultimate joint not bilobed. The pubescence is finer, more dense and recumbent than in Notoxus. Our species ap¬ pears to agree with the European in having the humeri not distinct, but broadly rounded. It is entirely testaceous in color except the su¬ tural margin, and an oval spot at the middle of the suture, which are nearly black. RHINOPLATIA, n. g. Mentum subquadrate, anterior angles rounded, apex truncate, and with two grooves and distinct median ridge slightly bifurcate in front, gular peduncle very prominent, rounded in front, fitting the basal emargination of mentum, ligula trapezoidal, coriaceous, emarginate in front. Last joint of palpi narrowly triangular, maxillary palpi long. Mandibles elongate, arcuate at tip and acute. Labrum elongate, quad- (1S) august, 1868. TRANS. AMER. ENT. SOC. 138 GEO. II. HORN, M. D. rate, angles rectangular. Eyes distant from prothorax, slightly oval and oblique. Antennae inserted between the eyes and anterior mar¬ gin of front, slender, filiform, eleven-jointed, joints equal, second joint one-half the length of the others. Head not narrowed behind the eyes, vertical in front, prolonged in a transversely compressed muzzle. Prothorax subcylindrical, sides slightly rounded anteriorly. Elytra elongate oval. Legs slender, tibiae bispinose, tarsi pubescent beueath, first joint longer, penultimate sub-bilobed. Five abdominal segments in both sexes, the terminal conical in male, broader in female. This genus of Oedemeridte supplies in our fauna the place of Chi- tona in the European. Differing from Chitona in the entire mandibles, the form of mentum, form and situation of the eyes. I regret not be- ing able to give more extended comparisons, having no specimens at my disposal of the European species. R. ruficollis, seneous-black, thorax rufous. Head glossy, sparsely and finely punctured and sparsely clothed with cinereous pubescence. Thorax one-half longer in 9 > or in twice as long as broad, subcylindrical, convex, sides feebly rounded ; shining, very sparsely punctured and very sparsely pubescent. Ely¬ tra elongate oval, humeri obtuse, more than twice as long as broad, rather coarsely and densely punctured and more densely clothed with recumbent ci¬ nereous pubescence. Abdomen and legs black, clothed with cinereous pubes¬ cence. Length .24 — .36 inch. Owen’s Valley, California, on flowers. The thorax is very variable in form in this species, generally much longer in the males and more robust in the females. In the majority of specimens it seems broader at base than at apex, and has the sides feebly sinuate behind. PRGSTENUS Latr. P. californicus, elongate, shining, cupreous or violaceous metallic; head coarsely punctured, thorax one-third broader than long, moderately convex, coarsely punctured, sides strongly rounded in front, rather suddenly narrowed at the posterior third, apex feebly emarginate, base broadly rounded, hind an¬ gles distinct. Elytra elongate-oval, truncate at base, humeri obtuse, sides mod¬ erately rounded, gradually narrowing at posterior third, with strife of rather coarse punctures, rather distantly placed, and an intermediate series of finer, very closely placed, punctures. Beneath metallic-blue, coarsely punctured. Length .40 inch. Two much injured specimens from Martinez, California. The occurrence of this genus so high up in California, gives rise to some doubts as to whether they may not have been imported. They were sent to me as collected, the bottle containing very little else of value, and nothing else of a foreign type. I have therefore described the species, and await the time when I shall be able to compare it with others already known. AMERICAN COLEOPTERA. 139 P0RE03PASTA, n. g. Characters of Meloe except, elytra not imbricate, contiguous along anterior third of margin; scutellum distinct, transverse, truncate; claws unequally cleft, lower portion of each claw very short, scarcely half as long as upper. Antennae gradually clavate, outer joints round¬ ed, last joint much longer and acute at tip. Another of the genera intermediate between Meloe and Heinous. P. polita, black, smooth, shining, head very distantly punctured and with a yellow spot; thorax broader than long, hexagonal, truncate at apex and base, sides subangulate, disc flat, sides usually orange-yellow; elytra smooth, nearly as long as abdomen, contiguous along anterior third; spurs of hind tibise dis¬ similar, equal in size, inner acute, outer cylindrical, compressed, obliquely truncate and concave at tip. Length .SO inch. The outline of elytra with abdomen is similar to that of Henous. Several injured specimens from the Southern Coast Range of Cali¬ fornia, collected by Mr. Win. M. Gabb. The addition of several new genera since the publication of the Synopsis by Dr. LeConte, renders it advisable to remodel the table in such a manner that the new genera may be introduced in natural se¬ quence. Elytra imbricated ; claws cleft . Meloe. Elytra divergent from scutellum ; claws toothed . Megetra. Elytral margins contiguous at anterior third. Claws equally cleft . Nomaspis. Claws with lower portion much shorter . Poreospasta. Elytra contiguous along entire margin. Claws cleft; elytra subconnate . Henous. Claws toothed; elytra connate and inflated . Cysteodemus. MEGETRA Lee. M. opaca, black, opaque, thorax pentagonal, broader than long, sides obtusely angulate; elytra opaque, intricately rugose. Spurs of hind tibiae long, slender, acute, the inner one longer. Length .50— 60 inch. Differ from our other species in its smaller size and by the peculiar blackness and opacity of the whole surface. The head has few punc¬ tures about the occiput. The elytra are relatively larger and broader than in our other species, and vary somewhat in sculpture from a rather coarse punctuation to the intricately rugose surface seen in the ely¬ tra of the other species. The tibial spurs are much more slender and acute and the tooth of the claws longer and less divergent. Found running ou the ground in March and April atTemacula, Cali¬ fornia, and one specimen from Fort Yuma. 140 GEO. II. HORN, M. D. NOMASPIS Lee. N. sublaevis, black, sub-opaque, epistome coarsely and densely punctured, front with a few, but very distant coarse punctures, and with a yellow rliora- boidal spot ; thorax broader than long, sides and anterior angles broadly round¬ ed, gradually narrowed behind, disc very finely rugose and with a few scattered punctures, and a feeble median impressed line. Elytra nearly as long as abdo¬ men, contiguous at anterior third, not imbricate, posteriorly strongly diverging, surface sub-opaque, indistinctly rugose and obsoletely finely punctured ; spurs of hind tibiae unequal, inner spur slender, short, acute, outer spur broad, thick, and very obliquely truncate. Length .38 inch. Abundantly distinct from parvula Lee., by its smoother surface and the character of the spurs of the hind tibiae, in the latter species they are both slender and equal. One specimen from Fort Tejon, California. LANGURIA Latr. L. convexicollis, black, shining, thorax rufous, head black, brownish between the eyes, sparsely and finely punctured; thorax quadrate, very convex, sides broadly rounded in front, slightly convergent behind, anteriorly feebly emar- ginate, posteriorly truncate, angles rectangular. Base finely margined, and edged with black, and with a short oblique impression on each side between the middle and the angles. Elytra elongate, sides gradually converging, finely striato-punctate, with the interstices finely wrinkled. Legs black. Length .42 inch. Owen's Valley, California. Oue specimen. The thorax of this species is more convex and with sides more broad¬ ly rounded than in any of our species with a quadrate thorax; the thorax is also very finely and sparsely punctured, the middle of the anterior margin and the whole of the posterior margin edged with black. The head, except between the eyes, is also black. AMERICAN COLEOPTERA. 141 Synopsis of the SCOLYTIDiE of America North of Mexico. BY C. ZIMMERMANN, M. D., With Notes and an Appendix by J. L. LeConte, M. D. [Among the MSS. of my deceased friend, Dr. Zimmermann, I find several partially completed memoirs, which contain not only systematic ideas of much value, but descriptions of many new species belonging to our fauna. His widow having kindly submitted the whole of the MSS. to me for examination, it is my intention from time to time to se¬ lect such groups as have not yet received attention from American stu¬ dents, and to preseut extracts from the MSS. which will secure for fu¬ ture reference at least a portion of the labor of the author ; it is a sub¬ ject of regret to me, that the different memoirs which he prepared were not furnished for publication without delay, for I find in them improvements in classification, unknown at the time of writing, though the most important have been since developed by other observers. On the present occasion, I give the result of his investigation of the family of Rhynchophora, known as Scolytidte but in the MSS. called Hylurgidad, for reasons which are detailed below. The Scolytidae are distinguished from the other families of Rhyn¬ chophora by the 3rd tarsal joint not being received in the 2nd, the an¬ tennas strongly clubbed and geniculate, and by the tibiae being serrate on the outer margin.* For the purpose of rendering the present contribution more com¬ plete I have added descriptions and references to species in my own collection, not mentioned in the MS. memoir before me; and where the views of other systematists differ from those of our author in re¬ sard to the limits of genera, X have called attention to the fact. The family Hylurgidte being thus defined by Dr. Zimmermann is divided by him into the following tribes : * Dr. Zimmermann has in a pencil note marked for investigation the relations between the present family and the Apatidce, (Bostrichidae of most authors!; al¬ though there is much resemblance in form, and to a certain extent in habits be¬ tween the two types, the latter fails in what I have regarded (Am. Journ. Sc. 1867, xliv,) as the defining character of the Rhynchophora, viz. the enclosure of the posterior extremity, of the prosternum by the side pieces of the prothorax. The resemblance between the two families in question is similar to that between Brenthidse and Colydiidse, or Rhyssodidse; or that between Anthribidie and certain Cerambycidee. To take a more familiar example, it is like the repeti¬ tion of forms observed in comparing Marsupials with placental Mammals. (19) SEPTEMBER, 1868. TRANS. AMER. ENT. SOC. 142 C. ZIMMERMANN, M. D. “ I. — Bostrychi: tarsi filiform, evidently 5-jointed ; beak obso¬ lete; containing Platypus , Crypturgus, Xyloterus, Bostrichus.

IIL — IIylurgi : 3rd joint of tar-si bilobed; beak very short and thick ; abdomen cylindrical ; containing Phloeotribus , Hylesinus , Den- droctonus, Hylurgus.” — Lec.] Tribe I. — Bostrychi. The beak is scarcely developed, but the great resemblance of these beetles in the method of life, and the structure of the body, (both in the larva and the perfect insect), with the genuine IIylurgi , demon¬ strates their true position in the system. They are distinguished from allied groups by the filiform tarsi, the 3rd joint of which is not dilated or bilobed. Club of antennas without trace of articulation; eyes round. 1. Prothorax truncate in front; elytra depressed ; 1st joint of tarsi as long as the others united.* . Platypus Herbst, Y. 128. Club of antennae articulated, eyes transverse, emarginate. 2.

The separation between the joints of the antennal club concentric, and visible only on the anterior surface, being covered on the other side by the first joint . Xyleborus Er. c.

CRYPTURGUS Er. All the species belonging to this genus have the tibiae compressed but slender, and scarcely dilated towards the tip ; according to differ¬ ences in the form of the prothorax, the front femora, and other parts of the body they may be arranged in three divisions. A. — Prothorax longer than wide; antennal club fringed at the sides with long hairs; front femora toothed at tip; outer surface of the an¬ terior tibiae, as in Platypus , with teeth like transverse ridges. f * No new species are described in the part of the memoir relating to Platy¬ pus, which is therefore omitted. — Lec.] I This division corresponds with the genus Corthylus Er., which differs from Crypturgus by the funiculus of the antennae consisting of but one joint, instead of tivo. The plan of arrangement pursued by the author does not take cogni¬ zance of the number of joints of the funiculus, and therefore definitions of the the two genera naturally fall together. — Lec.] AMERICAN COLEOPTERA. 143 C. fasciatus. =Bo.sfri'cAMs fasciatus Say, Journ.

Very abundant on pines. BOSTRYCHUS Fabr. The name Bostrichus (more properly Bostryclius) was first applied by Geoffrey to Apate capucina. Fabricius applied it to all the insects belonging to the tribe here under consideration, probably because the meaning of the name appeared to him more applicable to them than to Apate. Latreille adopted the nomenclature of Geoffroy, and there¬ fore proposed for the Bostrychi the name Tomicus, which has since been commonly adopted. More recently Erichson has divided this genus into many subgenera, of which those above defined (Crypturgiis,Xy- leborus and the present) can be regarded as well defined groups. The body in the species of the present subgenus is short cylindrical ; the prothorax is longer than wide, convex, roughly tuberculate in front j the elytra are obliquely suddenly declivous behind, and excavated, with the elevated margin toothed, while in the two preceding subgenera the posterior declivity of the elytra is formed in a different manner. The females differ from the males in the form of the prothorax, which in the former is somewhat longer and narrower in front. The species live mostly under the bark of coniferous trees; they appear sometimes in countless multitudes, and do immense mischief by killing the trees in the forests of pine and fir ; as was the case with B. pint in Caro- AMERICAN COLEOPTERA. 147 lina in 1847 — 49, and with B. stenographic and typograplius in Ger¬ many frequently since 1665.

This species is very similar to the European B. stenographic Creutzer ( =typographus Fabr.), but differs by the much more finely punctured hind part of the prothorax and by the posterior excavation of the elytra, which is more rugosely punctured, and hairy. Tribe III. — Hylurgi. The third joint of the tarsi is more or less diluted and bilobed, in which respect the insects of this tribe differ from those of the preced¬ ing ; the cylindrical convex abdomen separates them from Eccoptoga- steres. * The genera may be separated as follows : * Basal margin of the elytra acutely elevated and serrate; 1. Club of antennae composed of lamellae . Phloeotribus Latr. 2. Club of antennae composed of closely united joints, knob shaped ; the sub¬ genera are as follows : a. Club of antennae elongate oval, or spindle shaped, pointed at tip. Hylesinus Fabr. b. Club of antennae short and obtuse, sometimes thick and almost glo¬ bose, sometimes compressed, and concave . Dendroctonus Erich. ** Basal margin of elytra not acutely elevated : 3. Club of antennae short and thick, knob shaped, composed of closely uni¬ ted joints .

HYLURGUS Latr. These insects differ from those of the allied genus Dendroctonus by the more slender body, by the basal margin of the elytra being neither acutely elevated nor serrate, and by the more distinctly developed beak. The color is black, and only in freshly hatched individuals brown or ferruginous; but the antennae, tarsi, extremity of the tibiae and the front margin of the prothorax are generally ferruginous or brown. The species are distinguished chiefly by the form of the prothorax and the sculpture of the elytra. A. — Beak distinctly carinatod. H. scabripennis Zimm. — Long. 2 — 2£ lin. As long as the European H. ater but broader; upper surface glabrous; prothorax a little longer than wide, nar¬ rower in front, shining, tolerably sparsely punctured, the punctures thicker and finer in front than behind; elytra very deeply striate, the striae are less evidently punctured, but the intervals are very deeply rugose. — Atlantic States.

(20) TUANS. AMER. ENT. SOC. SEPTEMBER, 186S. 150 JOHN L. LECONTE, M. D. APPENDIX. BY JOHN L. LECONTE, M. D. For some years past there has been a growing tendency, especially in the Western States, where agricultural interests dominate, to the study of economic entomology. Unfortunately the efforts of industri¬ ous and meritorious observers are, in some instances, thwarted, or ren¬ dered of but little value, because the want of systematic knowledge re¬ garding the characters and consequently the proper nomenclature of the noxious objects has not yet been supplied by those who devote them¬ selves specially to the study of the differences in structure of these mi¬ nute insects. With a view to remedy in some degree this want, as far as regards the Scolytiile, among whom may be ranked some of the most formi¬ dable enemies of arboriculture, I have thought that descriptions of the species in my collection, which are not contained in the foregoing me¬ moir, might not be unacceptable in the present condition of agricul¬ tural science. The students familiar with the most recent works on entomology published abroad, will at once perceive that the classification of our author is much more elementary in its nature than those now generally adopted. Disregarding the number of small joints of the antennae com¬ posing the funiculus, between the club and the scape or elongated first joint, his system depends to a great extent on the form and structure of the club, the portion of the organ adapted for special sensibility. The value of the number of these joiuts, varying from 1 to 7. often very small, frequently very difficult to observe, seems to me to hive been greatly exaggerated by some modern systematists ; while admit¬ ting their usefulness in defining groups of species within the geuera, I am not disposed to introduce them into the generic formulae, except as accessory to more important differences in form and structure. Tribe I. — Platypini. The admirable monograph of Dr. Chapuis upon this tribe, so dis¬ tinct from the other two as almost to warrant its being viewed as a sub¬ family, obviates the necessity of any extended remarks upon the few species belonging to our fauna. The following references to the work will enable the student to identify the species, all of which belong to the genus Platypus, without trouble. AMERICAN COEEOPTER A. 151 1.

I may add to the brief description of this last named species which I wrote to Dr. Chapuis, that it approaches to, and is perhaps identical with his P. Blanchardi ; by an unfortunate clerical or typographical error the two acute tubercles or spines of the abdomen are stated to be on the 3d instead of the 4th ventral segment. The terminal process of the elytra is truncate, with rounded angles in one specimen, and on one side of a second, which is before me, while on the other side of the latter the two cusps mentioned in the description of P. Blanchardi may be seen. I infer, therefore, that they disappear with age. Dr. Zimmermann observes of these insects, that they “are found “mostly in pine logs ; they remain commonly about the foot of the “tree, where they make their dwellings; their presence is easily known “by the large heaps of worm-dust, (wurmmehl,) which they, by moving “backwards, push out of their galleries. In South Carolina, where “they occur abundantly, they also fly to the light in houses, on dark “ evenings, from March to October.” 1 Tribe II. — Tomicini. The occurrence in our fauna of several genera not represented in the Zimmermann collection, renders necessary a tabular statement of their affinities, which may be thus expressed: A. Head not completely covered by the prothorax, partly visible from above ; prothorax not tuberculate in front. Club large, flat, not annulated ; funiculus 2-jointed . Crypturgus. Club smaller, oval, annulated; funiculus 3-jointed . Aphanar thrum. B. Head completely overhung by the prothorax, which is very convex and tu¬ berculate in front. a. Club of antennae large, much compressed, transversely annulated on both surfaces; funiculus 1 — 5-jointed . Cryphalus. b. Club of antennae large, rounded, entirely corneous on one side, circularly annulate on the other, or solid. Eyes divided, club solid . Xyloterus. Eyes emarginate, club annulated . Xyleborus. c. Club of antennae entirely corneous on one side, transversely annulated on the other, the sutures being undulated. Elytra deeply excavated at tip, with the margin of the excavation strongly toothed . Tomicus. 152 JOHN L. LE CONTE, M. D. d. Club of antennae pubescent, with the exception of an elongated space extending from the base to the middle; sutures loop-shaoed, parallel with the smooth space . . . Micracis. With the exception of Gryplialus (including Cortht/lus and Cordiy- lomimus ), which is polymorphic, these genera are readily distinguished by a form and sculpture peculiar to each. CRYPTURGUS Er. C. atomus. — Slender, cylindrical, shining black, antennae and legs brown, slightly hairy on the head and at the sides of the thorax, and with rows of hairs upon the elytra; prothorax longer than wide, scarcely narrowed in front, slightly rounded on the sides, more rounded at the base and tip, uniformly sparsely but strongly punctured ; elytra with rows of large punctures, the sutural one im¬ pressed towards the base; intervals with scarcely perceptible rows of very small punctures. Long. 1 mm. New York, Mr. Ulke. The smallest of our Scolytidm. The club of the antennae is tolerably large, strongly compressed, oval, obliquely narrowed on the outer half, corneous, shining, and but slightly pubes¬ cent except on the oblique edges; the funiculus consists of but two small joints, the 2nd being much smaller than the first. The posterior declivity of the elytra is convex, without impressions. APHANARTHRUM Wollaston. To this genus heretofore known only from the Madera and Canary Islands, I would refer Hylastes pumilus Mann., from Alaska. It is scarcely over 1.5 mm. long, slender, cylindrical, dark brown, shining, very thinly clothed with a very short pubescence, forming lines upon the elytra; the prothorax is longer than wide, much narrowed in front of the middle, rounded on the sides, strongly rounded at tip, very feebly rounded at base, moderately convex, strongly and tolerably thickly punctured; elytra with striae of very large punctures, of which the 1st and 2nd are somewhat impressed, intervals with scarcely perceptible rows of very small punctures. This insect has nearly the form of the preceding, but under a pow¬ erful magnifier the club of the antennae is seen to be oval, not very much compressed, with the basal half corneous and shining, the outer half conical, annulated and pubescent; the funiculus is composed of three distinct joints, the 1st being the largest, and the 3rd the broadest, ob¬ lique and narrower at the inner side. The tarsi are very slightly dilated, the 3rd joint very feebly emarginate, thus establishing a relationship to the next tribe. The head is however short as in Crypturyus and somewhat prominent, though not at all rostrated as in Ilylurgini. AMERICAN COLEOPTERA. 15: This species has been made by Eichhoff, ( Berl . Ent. Zeitsclis. 18G8, p. 147), the type of a new genus Dolurgus ; the funiculus is described as 4-jointed, but after repeated examination, I am unable to perceive more than three joints the proportions of which I have endeavored to describe above. CRYPHALUS Er. I have combined under this name all those species which lmve the club of the antennae large, compressed, and transversely annulated on both surfaces. It consequently corresponds to Dr. Zimmermann’s genus Crypturgus which name cannot be retained for it as the typical European species, unknown to our author, is of a quite distinct type. With the enlarged definition of Cryphalus adopted by me, it will contain species of varied form, and differing in the number of joints of the funiculus of the antennae : the funiculus is however always short, and the joints, after the first, closely connected both with each other and with the base of the club. The species are numerous and may be grouped as follows : A. — Funiculus 1-jointed (base of club not articulated). This group corresponds with Corthylus . Er., and may be divided into two subgroups: I, Corthylomimus Ferrari, corresponding with the first division of Dr. Zimmermann’s Crypturgus , having the club of the antennae fringed, and the outer surface of the front tibiae trans¬ versely corrugated. II, Corthylus proper, with the club still larger, not fringed, and the front tibiae armed at the outer edge with a few small teeth. To the first subgroup belong the following species : * Posterior declivity of elytra flattened, feebly margined behind: 1. C. fasciatus. (Ante, p. 143.) 2. C. scutellaris Lee. Report R. R. Expl. to Pacific, xi. Insects, 59. California. s* Posterior declivity of elytra concave, acutely margined behind: 3. C. cavus. — Black, moderately shining, elytra brown, darker towards the tips, antennae yellowish, feet brown ; head convex, strongly not densely punc¬ tured; prothorax finely roughened near the tip, nearly smooth behind, about one-third longer than wide, parallel on the sides, obtusely rounded in front; elytra very finely punctulate and rugose, posterior declivity deeply excavated and hairy, with its margin strongly elevated for more than one-half the ex¬ tent, ending in an acute cusp, above which, continuing the outline of the de¬ clivity and nearer the suture are three other small denticulations ; the suture along the declivity is elevated. Long. 3‘5 mm. One specimen of this very distiuct species was given me by Dr. G-. H. Horn, as collected in the coast region of California, south of San Francisco. 154 JOHN L. LECONTE, M. D. *** Posterior declivity of elytra with subsutural tubercles : 4. C. dentiger. — Slender cylindrical, not very shining, nearly glabrous, dark brown, posterior half of prothorax, antennae and feet brownish-yellow; bead flat, opake, finely punctured ; prothorax nearly one-half longer than wide, pa¬ rallel on the sides, obtusely rounded in front, finely roughened in front of the middle, nearly smooth behind; elytra very indistinctly and sparsely punctu- late, posterior declivity slightly concave, elevated margin acute below, then ris¬ ing into a small acute cusp, then becoming thick and retuse for a short distance, then armed near the suture with another small acute cusp or small spine; the suture is not elevated, and near it on each side, about the 2nd third of the de¬ clivity is a small rounded subacute tubercle. Long. 2 mm. One specimen from middle California given me by Dr. Horn. This species is of the same size and form as C. mail, but differs in the pos¬ terior declivity of the elytra, as above described, being concave and broadly retuse at its lateral margin. 5. C. mali. (Ante, p. 143.) To the 2nd subgroup, or Corthylus proper, belongs only 6. C. punctatissimus Zimm. (Ante, p. 144.) B. — Funiculus of antennae 2-jointed, body stout, head large, promi¬ nent, and deflexed. But one species of this group is known to me : 7. C. dissimilis Zimm. (Ante, p. 144.) This differs remarkably from the others in form, and resembles somewhat the figure of Hi/pothonemus in DuVal, Gen. Col. Eur. iv, pi. 33, fig. 101, but is stouter. C. — Funiculus of anteunae 4 or 5-jointed, (except in No. 16,) outer joints closely connected with each other, forming a pedicel to the club. Several subgroups may be recognised, and the species tabulated for convenient reference as follows: ® Club of antennae feebly annulated, more shining ; elytra shining, scarcely punctured : Posterior declivity of elytra strongly retuse . 8. retusus. Posterior declivity of elytra feebly retuse . 9. sulcatus. Posterior declivity of elytra not retuse : Thorax moderately rough in front . 10. materiarius. Thorax very rough in front, (very small) . 11. asperulus. **- Club of antennae distinctly annulated, less shining, sutures transverse near¬ ly straight : a.

Elytra with more or less distinct rows of punctures, posterior declivity broadly sulcate near the suture : Thorax finely punctulate behind, with a large patch of hair each side in front of the middle . 17. comatus. Thorax coarsely punctured behind, without patches of hair. — Trypo- phlceus Fairmaire. Subsutural groove of declivity broad and deep : Elytra coarsely punctured in rows . 18. pullus. Elytra coarsely punctured, but not in rows . 19. pulicarius. Elytra more finely punctured in rows: Prothorax regularly rounded in front . 20. atratulus. Prothorax slightly constricted near the tip. 21. nitidulus. Subsutural groove of declivity very faint : Elytra more finely and confusedly punctured. 22. puberulus. 8. C. retusus. — Cylindrical, slender, blackish-brown, base of elytra paler, an¬ tennas and feet yellowish; head prominent, convex, subcarinated, shining, sparsely punctured; protliorax nearly one-half longer than wide, sides slight¬ ly converging from the base and feebly rounded, tip strongly rounded, surface rough and sparsely hairy before the middle, granules tolerably coarse near the tip, behind the middle sparsely punctulate; elytra very finely rugose and dis¬ tantly punctulate in rows, and with a few long hairs behind the middle, poste¬ rior declivity with a deep depression along the suture, limited each side by a longitudinal obtuse elevation, bearing on its highest portion a few very fine denticulations ; suture not elevated. Long. 3-5 mm. Collected in the coast region of California and Oregon by Dr. Horn. This species has the same form and sculpture as C. materiarius, but is larger and readily distinguished by the different sculpture of the pos¬ terior declivity of the elytra. 9. C. sulcatus. — Form, size and sculpture precisely the same as in C. retusus, except that the front is divergently aciculate, and the occiput is sparsely punc¬ tured ; the elytra are similarly punctulate in rows, but the general surface is more distinctly and densely rugose; the retuse elevation of the posterior de¬ clivity of the elytra is but slightly prominent, and not denticulate; the hairs behind the middle of the elytra are less numerous. Long. 3‘5 mm. One specimen from the coast region of middle California, given me by Dr. Horn. The color is paler than that of the three specimens of C. retusus now before me, being yellowish-brown, with the base of the thorax, and the sides and tip of the elytra darker. Probably more mature specimens would be darker; it is perhaps the female of the preceding, but having failed to fiud any sexual characters in C. ma¬ teriarius , I am not warranted at present in so regarding it. 11. C. asperulus. — Slender, cylindrical, brownish-black, shining, nearly gla¬ brous, antennae and feet yellow; head flat, feebly punctulate; prothorax one- half longer than wide, feebly narrowed and rounded on the sides from the base, strongly rounded at tip, very rough and slightly pubescent before the inddle, but almost entirely smooth behind ; elytra scarcely punctulate, posterior de¬ clivity with a few hairs, almost uniformly convex, with a very feeble subsuiu- ral furrow. Long. 1*5 mm. 156 JOHN L. LECONTE, M. D. One specimen from Virginia, given me by Mr. E. T. Cresson. With the exception of C. hispid ulus, puber ulus and Crypturgus atomus , this is the smallest native Scolytide known to me. The elytra under a high magnifying power show some very faint rows of small punctures. 13. C. pubipennis.=!Tomcw.s pubip. Lee. R. R. Expl. to Pacific, xi, Ins. 59. California. 14. C. pilosulus.— Elongate, cylindrical, yellow ferruginous, shining, front hairy; prothorax longer than wide, finely asperate in front, tolerably densely punctured behind, uniformly clothed with fine pubescence; elytra tolerably densely and finely punctured, and clothed with fine erect hairs, without any appearance of strise, obliquely declivous and slightly flattened behind. Long. 2 myi. I found one specimen of this species in middle California; others were collected by Dr. Horn in the southwestern part of the State. 15. C. hispidulus. — Moderately elongate, black, scape and first joint of funi¬ culus of antennae, tibiae and tarsi ferruginous; head prominent convex, finely reticulate ; prothorax not longer than wide, convex, before the middle rough with acute reclinate tubercles, rugoselv punctured behind, clothed with short still' hairs ; elytra with approximate rows of quadrate punctures, intervals narrow, with rows of close set short stiff erect gray bristles ; posterior declivity rounded, not at all flattened. Long. 1 — 1-5 mm. District of Columbia, Georgia, Louisiana ; this species, though evi¬ dently related to C. dissimilis, has the outer portion of the funiculus, or rather the pedicel of the club of the antennae, slender and divided by very fine transverse sutures, the base of the club is shining and smooth. 16. C. striatus. — Elongate cylindrical, dark brown, antennae and feet yellow; head prominent, convex, punctured, slightly pubescent, with a smooth trans¬ verse frontal elevation; prothorax longer than wide, convex, finely roughened in front, with a few larger tubercles, which are somewhat acute, tolerably densely and coarsely punctured behind, sparsely clothed with short hairs; elytra with approximate rows of large quadrate punctures, intervals each with a series of very fine punctures bearing short yellowish hairs; tip obliquely declivous, very slightly flattened. Long. 2 mm. This species is widely distributed. I have several specimens col¬ lected at Cape San Lucas, Lower California, by Mr. John Xantus, others were found in Middle California by Dr. Horn, and I have seen two in the collection of the American Entomological Society which came from Illinois. The club of the antennae is very distinctly annu- lated, the outer part of the funiculus is divided by one transverse suture, visible only under a compound microscope; it is therefore only 3-jointed; the first joint is larger than the other two united. 20. C. atratulus. — Elongate cylindrical, black, antennae and feet very dark brown; front clothed with long hair fprothorax longer than wide, sides nearly straight and parallel, disc rough with elevated tubercles in front, strongly but AMERICAN COLEOPTERA. 157 not densely punctured behind, with a broad, smooth dorsal line; elytra with rows of moderately fine close set punctures, here and there somewhat irregular, intervals broad flat, the alternate ones with a few distant punctures; tip ob¬ liquely declivous, broadly and deeply sulcate along the suture, and with a few erect hairs. Long. 2 mm. Two specimens, Cabo de los Reyes, California, Mr. George Davidson. Related to C. pullus, but with the elytra punctured as in C. nrtidu- lus, from which it differs chiefly by the form of the thorax, which is more parallel on the sides, and not at all constricted, but regularly rounded near the tip. 21. C. nitidulus.= Bostrichus nitid. Mannh. Bull. Mosc. 1843,298; 1 846, 359. Sitka. This species resembles C. pullus Zimm., but differs by the punctures of the rows of the elytra being much finer and more closely placed, and the intervals therefore wider and more even ; the protho- rax is also distinctly rounded on the sides, and slightly constricted near the tips. 22. C. puberulus. — Cylindrical, moderately slender, black, thinly clothed with short erect gray hairs; head slightly convex, punctulate ; prothorax a little longer than wide, slightly narrowed in front, feebly rounded on the sides, broadly rounded at base, and more strongly at tip, disc rough, with reclinate tubercles in front of the middle, strongly but finely punctured at the sides and behind ; elytra about one-half longer than the prothorax, strongly but finely punctured, but not in rows, posterior declivity not at all flattened, slightly con¬ vex, with a well marked sutural stria extending from the tip one-third the length of the elytra, tip of suture slightly acute, (but not acuminate, as in Micracis.) Long, less than 1‘5 mm. One specimen from District of Columbia given me by Mr. Ulke. This is among our smallest species, and somewhat resembles C. minu- tissimus Zimm. in form, but is smaller and much less finely punctured, and is narrower. It is easily distinguished by the absence of the fringe of long hairs on the head, and by the w7ell marked, though nar¬ row sutural stria extending from behind the middle to the tip of the elytra; the acuteness of the sutural angle induces me to believe that this is perhaps Tomicus pusillus, Fitch, Noxious Ins. New York, ii, No. 245. The funiculus of the antennae in this species is 5-jointed, the outer joints 2 — 5 being closely connected, forming a pedicel to the club, as in the group Tri/pophlceus Fairmaire, DuVal, Col. Europe, iv. pi 33, fig. 160; in the proportions of the body and in sculpture our species also resembles the figure cited. A similar structure of the funiculus is seen in C. nitidulus , atratulus, pul/us and pulicarius. C. comatus , so anomalous by the two tufts of hair on the prothorax, seems to be¬ long rather to the typical Gryphalus ; at least, so far as the condition (21) SEPTEMBER, 1S6S. TRANS. AMER. ENT. SOC. 158 JOHN L. LE CONTE, M. D. of the specimen permits an examination, the funiculus appears to be 4-jointed. XYLOTERUS Er. In this genus the club of the antennae is large, pubescent, oval, solid and not at all anuulated, with a somewhat smooth elongate spot extending from the base to the middle ; the funiculus is 4-jointed, and the eyes are so deeply emarginate as to become completely di¬ vided. No species of this genus is contained in the collection of Dr. Zim- mermann, and the name was applied by him to some species not sepa¬ rated by Erichsou from Tomicus, hut which now form the genus Xt/le- borus Eichh.; I have taken the liberty of substituting the latter name in his MSS. Mr. A. Puton* observes that the European species of this ge¬ nus do not make their galleries between the inner bark and the wood, as is the case with nearly all the insects of this family, but bur¬ row deeply into the wood itself, thus greatly injuring the value of the trees which they attack. Our species, without doubt, will be found to have similar habits. 1. X. retusus. — Cylindrical, rather stout, blackish brown, shining ,- head ( % ) deeply concave, sparsely finely punctured, clothed with erect hairs; prothorax much broader than long, rather quadrate in form, being as broadly rounded at tip as at base, convex, very strongly declivous and broadly impressed near the tip; asperate with transverse granulations, and clothed with long erect hair in front, finely, not densely punctured behind; elytra with distant rows of rather fine and not deeply impressed punctures, each with a testaceous vitta abbrevi¬ ated before and behind. Long. 4-5 mm. One specimen from Canada given me by Dr. Horn. Resembles the next, but is much larger, easily distinguished by the form of the thorax, which is more abruptly declivous in front, and broadly retuse. 2. X. bivittatus Mannh. Bull.

Maine to Alaska. In the male the head is concave, and the thorax finely transversely asperate before the middle; in the female, the head is convex, and the thorax much more roughly asperate. This species varies greatly in color, the black elytral vittae sometimes occupy nearly the whole surface, and sometimes are almost wanting. 3. X. scabricollis. I have received from Mr. Ulke a remarkable male, having the head deeply concave, as usual, but the thorax is as rough iu front as in the * Ann, Soc. Ent. France, 1867, p. 634. AMERICAN COLEOPTERA. 159 $ of A”. bwittatus, and covered behind with anastomosing curved lines, leaving between them flattened granules ; the elytra are shining, and the punctures of the rows are larger and more strongly impressed; the color is uniform reddish brown, with the antennae and feet paler.

Narrower than the other species, more hairy, and easily known by the punctures of the elytral rows being larger and more distant; the club of the antennae is broader and less oval. 1 have seen no specimens with concave head. XYLEBORUS Eichhoff. These species have the eyes slightly emarginate ; the outer (or pos¬ terior) face of the antennal club is corneous and shining, the inner face equally so, except at the end, where there is an oval pubescent cir¬ cularly annulated space ; the outline viewed from the outer face ap¬ pears truncate, and sometimes almost obtusely pointed at the side. In all the species known to me, the first joint of the funiculus of the antennae is longer and thicker, equal in length to the others united, which, varying in number from three to four, are closely joined, form¬ ing a conical mass, the separations of which are visible only with a very high magnifying power. They may be grouped as follows : A. — Body stout cylindrical, thorax not longer than wide, funiculus of antennae 4-jointed. 1. X. tachygraphus.=Xy/e5orws iacliygr. Zimm. (Ante, p. 144.) 2. X. pyii. =Scolptus pyri Harris. (Ante, p. 144.) 3. X. obesus. — Short and stout, cylindrical, blackish-brown, thinly clothed with long soft erect pale hairs, antennse reddish-brown : head convex, coarsely but not densely punctured; prothorax rather broader than long, strongly roughened with subacute tubercles in front, nearly smooth behind ; elytra with rows of large punctures, not very closely set, intervals flat marked with small distant punctures from which proceed the long hairs; tip> obliquely declivous, not tuberculate, but with the striae somewhat imjiressed, and the side and tip acutely margined, as in the two preceding species. Long. 3 mm. Virginia, Massachusetts and Canada. Differs from the two pre¬ ceding by its much stouter form and by the absence of the small acute tubercles of the declivous tip of the elytra. B. — Body usually slender cylindrical, posterior declivity of elytra obliquely and strongly flattened, with rows of tubercles or teeth; funi¬ culus of antennae 5-jointed — Xyleborus Eichhoff. a. — Tibiae finely serrate. 4. X. celsus Eichh. Berl. Ent. Zeitschr. 1867, 400. (Ante, p. 145.) 160 JOHN L. LECONTE, M. D. 5. X. biographus. — Cylindrical, not very slender, chestnut-brown, antennae and feet paler, shining, thinly clothed with very long hairs ; head sparsely punctured, prothorax ( % ) longer than wide, broadly and deeply excavated before the middle, and covered with flat granules, producing an imbricated ap¬ pearance, anterior margin obtusely angulated ; the surface at the sides is sparsely punctured, and near the middle of the base is almost smooth; elytra less than twice as long as the prothorax, with rows of large feebly impressed punctures, posterior declivity flat, impunctured, with three acute tubercles each side equally distant from the suture and the margin of the declivity, which is marked with a second row of three or four smaller teeth, and outside of these again are two or three scarcely perceptible denticles. Long. 3 mm. One male from Illinois is before me. This species seems to be the analogue of the European X. monographus , the male of which has the thorax similarly impressed and retuse. It is also related to X. re- tusicoUis Zimm., but differs by its larger size, less prominent tubercles of the apical declivity of the elytra, as well as by minor differences in sculpture. 6.

The circularly annulate portion of the club of the antennae is larger than in the other species, (except X. sparsus and plagiatus ,) and the smooth basal part correspondingly smaller, showing therefore the same tendency towards Tomicus mentioned below. c. — Tibiae with only a few small teeth, anterior pair narrower than the others. 13. X. sparsus. — Elongate cylindrical, blackish-brown, shining, sparsely clothed with very long erect hairs; antennee and feet dark ferruginous; head densely pilose, with long yellow hair, prothorax a little longer than wide, coarsely asperate in front, coarsely and sparsely punctured behind, with an elongated, smooth dorsal space; anterior margin fringed with hairs which are half as long as the thorax; elytra withvrows of distant coarse punctures, inter¬ vals with more distant but equally coarse punctures, so that at first sight the punctuation appears confused; tip obliquely declivous, impunctured, except in the subsutural furrow, which is well marked, face of the declivity each side with two large acute tubercles, and a third smaller one at the upper edge of the slope, margin of the slope with a few (three or four) small denticles; extreme tip slightly produced into an acute j)oint. Long. 2 mm. (Jue specimen from Point Kewenaw, Lake Superior. The tibiae in AMERICAN COLEOPTERA. 161 this species are less dilated and less distinctly serrate than in those above mentioned. 14. X. plagiatus. — Less slender, ferruginous brown, shining, thinly clothed with long erect hairs ; antennae and legs paler ; head convex, punctured, with a triangular, opake, pubescent, frontal spot; prothorax scarcely longer than wide, sides parallel behind, then semicireularlv rounded with the apex; base very distinctly rounded towards the sides, surface strongly roughened before the middle, finely but deeply punctured behind, with a smooth oval space each side just behind the middle; elytra strongly but not densely punctured, punc¬ tures not arranged in rows ; posterior declivity strongly toothed ( % ), or almost unarmed ( 9 ) scarcely punctured, suture elevated. Long. 2 mm. Male with the posterior declivity of the elytra deeply concave, with the margin semicircularly elevated from near the tip to near the suture, armed at its upper limit with a robust horn, slightly hooked at the tip, then with two or three denticles, and ending below in a rather prominent tooth. Female with the posterior declivity somewhat retuse each side, and deeply sulcate near the suture, with a very small denticle near the suture, and a larger subacute tubercle near the tip. Maryland, Mr. H. Ulke. I infer that these two forms are the sexes of the same species, on account of the identity in sculpture of the thorax, and because the sexes of the European Tomicus bidens as figured by Ratzeburg, differ in a somewhat similar manner. The smooth basal portion of the antennal club is smaller in this than in the other species, and the sutures of the apical portion are less curved, being, in fact, nearly straight; in these respects it tends to¬ wards one of the groups of Tomicus ( pini , interruptus , &c.), but dif¬ fers by the elevated margin of the posterior declivity not extending to the tip, and by the sparse confused puncturing of the elytra ; the tibirn are less dilated than usual, and armed with a few not very pro¬ minent teeth, very nearly as in the preceding species, to which it is evidently allied. C. — Body moderately slender, cylindrical, tip of elytra obliquely declivous, scarcely flattened, without tubercles; funiculus of antennae 5-joiuted — Dryocxetes Eichhoff. 15.

With a large series of specimens before me, and types of both of the descriptions of Mannerheim, I perceive no differences which permit them to be distinguished as species. The specimens of semicastaneus have no appearance of a smooth dorsal prothoracic line; the single AXa&k-Aiy^septentrionis has it feebly apparent; in other specimens from Lake Superior, New York and Virginia it is quite obvious. 162 JOHN L. LECONTE, M. D. 16. X. a,ff&ber.=Bostrichus affaber Mannh. Bull. Mosc. 1852, 359. Alaska and Lake Superior. Differs from the preceding by its smaller size, and by the prothorax being slightly asperated in front. 17. X. granicollis. — Ferruginous, elongate cylindrical, sparsely clothed with erect hairs; head with a few granules and punctures ; prothorax longer than wide, densely granulate on the whole surface, scarcely more strongly in front than behind, smooth dorsal line narrow, scarcely visible; elytra with rows of large quadrate punctures, intervals narrow, with single rows of small punctures ; su¬ tural stria well impressed, tip obliquely declivous, not flattened, but slightly retuse from the depth of the subsutural furrow. Long. 2 mm. One specimen found in the mountains of Sullivan county, Penn¬ sylvania. Much resembles in its sculpture Crypturgus striatuhis Lee., but differs totally in the form and structure of the antennal club. TOMICUS Latr. This genus in its most restricted sense corresponds with the sub¬ genus Bostrychus of Dr. Zimmermann, and is easily recognized by the antennal club being corneous on the posterior face, and divided on the other side by sutures which are angulated or sinuate, the principal con¬ vexity of the suture being directed forwards; the funiculus is always composed of five distinct joints, and the tibiae are strongly toothed. The declivous portion of the elytra is deeply excavated, the excavation is margined behind, the margin extends to the suture a little in front of the sutural angle, and is strongly toothed at the sides; the punctures are arranged in distant rows, the intervals broad and flat, sometimes marked with a few punctures, sometimes smooth. According to the form of the sutures of the antennal club, our species represent three divisions: A. — Sutures of the club angulated, the point of the angle directed forwards. 1.

A larger form, 7 mm. long, occurs in New Mexico. 2. T. cacographus. — Cylindrical, dark-brown, or ferruginous, sparsely clothed with long yellow hairs; similar in sculpture to the preceding, but a little more slender in form ; the disc of the prothorax behind the middle is feebly punc¬ tured, the punctures of the elytral striae are transverse, and those of the inter¬ vals are well marked ; the posterior excavation is armed each side with but five teeth, of which the most anterior one is very small, the 3d large, 2d still larger, 4th and 5th moderate in size, the posterior elevated margin is not longer than in T. calligraphus, not dentate, but perfect in outline, as in T. pirn. Long. 3-5 mm. Southern and "Western States. Varies in color like the other species. I have two large specimens, more than 4 mm. long, one from Arizona and one from Illinois which do not seem to differ appreciably from the smaller eastern specimens of this species. AMERICAN COLEOrTERA. 163 3. T. plastographus. — Also of the same form and sculpture as T. calligraphus ; the middle part of the disc of the prothorax behind is less punctured, with a narrow smooth space; the strise of the elytra are composed of transverse punc¬ tures, and the intervals as far as the 5th are nearly free from punctures; the subsutural interval is, however, somewhat rugose towards the declivity, as in that species; the declivity is less deeply excavated, and armed each side with but four teeth, the anterior one being very small, the 2d and 3d large, some¬ what connected together, and the. 4th moderate in size, the posterior elevated margin is as long as in T. pint, extending one-third the circumference of the excavation. Long. 4 — 5 mm. California, one specimen. This species so resembles in the arma¬ ture of the posterior excavation of the elytra T. pint, that I con¬ founded it with that species. On close comparison, however, the dif¬ ferences are quite apparent, consisting not only in the transverse and coarser punctures of the elytral strise, but in the sutures of the antennal club, which are strongly angulated at the middle, and again in a back¬ ward direction near the inner side. B. — Antennal club with the first suture nearly straight, 2d bisinu- ate; posterior margin of the declivity of the elytra much longer. 4. T. pini. Bostrichus pini Say; Tomicus prcefrictus EichhofF, Berl. Ent. Zeitschr. 1867, 401. (Ante, p. 147.) Atlantic States, Canada, Oregon. In this species the punctures of the rows of the elytra are not transverse, and the intervals are nearly free from punctures ; the posterior declivity is deeply excavated, acutely margined below for rather more than one-third of its circum¬ ference, and armed each side with four teeth, of which the 1st is small, the 3d usually longer than the 2d, but more or less connected with it, the 4th shorter than the 3d, and acute. The thorax is deeply, but rather finely punctured behind towards the middle, with a narrow, ill defined, smooth dorsal space. Long. 4 mm. A larger and somewhat stouter form occurs in the Hudson Bay Territory, but I am not disposed to view it as indicating a different species. Four specimens are in my collection, and I have seen several others; they are about 5.5 mm. long., and are more hairy than the ordinary form. A smaller specimen from Hudson Bay Territory differs from T. in- terruptus by the head being shorter and more coarsely punctured, just as in r.p ini. but the intervals of the elytra have rows of very distant punctures, not so numerous as in T. interruptus , and the striae are composed of more close set punctures, as in T. pini. It is probably a distinct species, but I am unwilling to impose a name upon the single specimen before me. 164 JOHN L. LECONTE, M. D. 5. T. interruptus. — Bostrichus interruptus Mannh. Bull. Mosc. 1852, 357. Alaska. This species is of the same size and form as the smaller race of T. pint , but is more hairy, with the elytral strise composed of more distant punctures, and the intervals marked with rows of punc¬ tures but little smaller than those of the striae ; the posterior declivity is just as in T. pint; the punctures of the hind part of the thorax are rather deeper and more distant. The part of the head in front of the eyes is longer and more finely punctured than in T. pini. Long. 4-5 mm. 6. T. tridens.=-Bos&b.=Hylurgus ser. Mannli. ibid. 1843, 206; 1852, 356.

H. fasciatus. — Elliptical, convex, brownish-black, slightly pubescent, densely covered with black opake scales ; head concave, with a narrow polished median line; prothorax twice as wide as long, strongly narrowed in front, broadly rounded on the sides, near the base and tip with bands of pale scales and hairs, the hinder one broadly interrupted at the middle; elytra with a band before the middle, consisting of a large sutural spot and some smaller ones towards the sides, a narrow, nearly complete band behind the middle, composed of pale ashy scales; tip with a few ashy scales; strise deep, punctured. Long. l-5 mm. One specimen, York county, Pennsylvania. The club of the an¬ tennae is one-half longer than wide, regularly oval, less acute than usual, and the basal part is less pubescent and more shining. 6. H. opaculus. — Cylindrical, brownish-black, opake, thinly clothed with short stiff yellow hairs; antennse and feet ferruginous; head convex, thickly punc¬ tured ; prothorax nearly as long as wide, narrowed in front, sides subsinuate near the tip; densely but not finely punctured, with a very narrow faint dorsal carina; elytra with strise composed of deep subquadrate punctures, intervals narrow, rough with transverse rugosities. Long. 2-5 mm. Two specimens, Pennsylvania. The club of the antennae is sub- ovate, nearly twice as long as wide, and more shining towards the base. 13. 7. H. dentatus Say, Journ. Acad. Nat. Sci. Phil, v, 258. Middle and Northern States, and Oregon; under bark of Juniperus. This species, as observed by Say, strongly resembles in its specific cha¬ racters Phloeotribus frontalis , but is always larger, being usually over 2 mm. long. In one sex the prothorax is much more rounded on the sides and more suddenly narrowed near the tip than in the other. 8. H. serratus Lee. One specimen, New York. 9. H. cristatus Lee. California, Mr. Ulke. This and the preceding species closely resemble H. dentatus and differ chiefly by the larger size and by the greater elevation and stronger ser¬ ration of the third interval on the posterior declivity of the elytra; H. serratus also has the sutural space strongly elevated and toothed, while in H. cristatus, although serrate, it is much less elevated. AMERICAN COLEOPTERA. 171 10. H. hystrix Lee. Proc. Acad. Nat. Sci. Phila. 1858, 81. San Diego, California. This and the three preceding species have the third joint of the tarsi less dilated than in those of division A, and rather emarginate than bilobed. They approach in this character and in the funiculus of the antennae the genus H/lunju s, but differ by the larger club, the finely toothed tibiae and the form of the body. CNESINUS Lee. (n. g.) Elongate cylindrical, head convex, beak very short, eyes oblique, transverse, broadly emarginated, finely granulated ; antennae with the scape as long as the funiculus, much curved, slender at base, mode¬ rately thickened towards the tip; first joint of the funiculus thick, as broad as long, remaining joints forming an elongate mass, gradually becoming wider externally, showing under a high magnifying power the appearance of six closely connected joints; club elongate oval, somewhat shining except at tip, feebly pubescent, transversely annulate, the sutures furnished with fringes of long hairs; prothorax longitudi¬ nally aciculate; elytra deeply striate, convex at tip, basal edge acute and serrate ; front tibiae dilated, armed externally near the tip, which is prolonged, with large acute teeth ; middle and hind tibiae dilated, feebly serrate ; tarsi with the joints 1 — 3 moderately dilated, 3d emarginate, 4th slender, as long as the two preceding united; 1st joint of front tarsi shorter than the 2d, of the middle and hind tarsi equal to it. The anterior coxae are large and prominent, widely separated; the mesosternum is protuberant. A peculiar genus, differing in appearance from the others of the tribe by the more cylindrical form, the prothorax being parallel on the sides, except near the apex, where they are rounded. The sculpture of the prothorax is also unusual, being composed of dense longitudinal aciculations. C. strigicollis.— Cylindrical, dark brown, clothed with yellowish hairs, which are more stiff and arranged in rows upon the elytra; front flattened, nearly smooth, with a fringe of yellow hairs; prothorax longer than wide, convex, sides parallel to near the tip, where they are rounded, tip two-thirds as wide as the base; disc uniformly and densely covered with short longitudinal acicu¬ late punctures; elytra with deep punctured striae, intervals flat, with very fine rugosities; tip obliquely declivous, and broadly sulcate along the suture. Long, nearly 3 mm. Two specimens, Illinois. 172 JOHN L. LECONTE, M. D. HYLURGTTS Latr. This genus as defined by Dr. Zinimermann is equivalent to Hylns- tes Er., and the species will be referred to under that heading. The one described below, however, corresponds exactly with the European type, having the club small, oval, rather thick, distinctly annulated, pointed at the tip, very thinly pubescent, shining and nearly glabrous at the base; the funiculus is as long as the club, and composed of 6 dis¬ tinct joints, of which the 2nd to the 5th gradually increase in width, the 1st is larger and thicker than the others. The tibiae are dilated, and armed with a few distinct teeth near the tip. The tarsi are broken in my specimen, but are described as having the 3rd joint emarginate, not wider than the 2d. The body is long and cylindrical, shining, with a few fiue erect hairs on the elytra, which are feebly striate with rows of punctures; the intervals are marked with irregular double series of very small punctures, and single rows of very small tubercles gradu¬ ally becoming* larger towards the tip, which is convex, and broadly sulcate along the 2d interval, which is free from tubercles on the de¬ clivous portion. K. analogus. — Differs from the European II. ligniperda by the thorax being strongly but not densely punctured, without any distinct smooth dorsal line. Long. 4 mm. One speeiinen, New York; more slender in form than our Bend roc- tonus and easily recognized by its more shining appearance. CARPIIOBORUS Eichhoff. This genus is quite distinct by the 1st joint of the tarsi being shorter than the 2d ; the 3d is not broader, and is moderately emargin¬ ate, the 4th is as long as the others united: the tibiae are dilated and distinctly toothed towards the tip, the front pair are armed with a strong hook at the inner angle as in Dendroctonus from which this genus differs by the form of the antennal club, and the shape of the body, which is slender and cylindrical. The club is oval, thick, a little longer than wide, transversely annulated, obtuse at tip, glabrous at base : the funiculus is 5-jointed, the 1st joint larger and thicker, the others forming a conical mass. C. bifurcus Eichh. Berl. Ent. Zeitsclir. 1868, 147. (Ante, p. 148.) DENDROCTONUS Er. Following the example of the latest European authors, I would re¬ strict this name to the species having a short broadly rounded club, rather truncate at tip, shining aud nearly glabrous over its whole surface, strongly compressed and concave externally; the funiculus is composed of 5 distinct joints, the 1st thick and rounded, the others gradually AMERICAN COLEOPTERA. 173 becoming wider and forming a conical mass, about as long as the club : the scape is more thickened at tip than in the allied genera, being more than twice as wide as the 1st joint of the funiculus. The tibiae are very strongly toothed on the outer margin, the 1st joint of the tarsi is longer than the 2d, and the 3d is broader and bilo- bed, the front tibiae are armed with a strong apical hook. The 2d, 3d and 4th ventral sutures are strongly bent backwards at the margin, as in some Curculionidae; a character not seen in any of the allied genera. Our species may be tabulated as follows : A. Prothorax narrowed in front: Intervals of elytra rough for their whole extent, hairs moderate : Thorax very densely coarsely punctured . 1. terebrans. Thorax less densely punctured . 2. obesus. Intervals of elytra rough in front, only punctured behind, hairs long: Thorax unequally punctured; . 3. rufipennis. Thorax more sparsely punctured, intervals of elytra less rough. 4. punctatns. Thorax strongly punctured, intervals of elytra scarcely gran¬ ulated, even in front . . . 5. simplex. B. Prothorax scarcely narrowed in front, head very large: Intervals of the elytra slightly rough, pubescence short . 6. frontalis. 1. D. terebrans Lac. Gen. Col. vii, 361. =D. valens Lee. Pac. R. R.

D. punctatus. — Of the same form as D. terebrans. The erect hairs are much longer, the punctures of the prothorax much less dense, and the elytra are roughened only near the base, the intervals being finely and sparsely punc¬ tured behind, without elevated granules. Long. 6 mm. One specimen, northern New York. 5. D. simplex. — Of the same form as the smaller race of D. obesus, but with the thorax more coarsely punctured, the elytra less ’roughened in front, more obliquely declivous and somewhat flattened behind, with the intervals on the declivity absolutely free from tubercles, and marked only with ranges of pili¬ ferous punctures; the sutural stria is much deeper. Long. 4 mm. Two specimens from Canada are in my collection. 6. D. frontalis Zimm. (Ante, p. 149.) (23) TRANS. AMER. ENT. SOC. SEPTEMBER, 1868. 174 JOHN L. LECONTE, M. D. HYLASTES Er. Tn this genus the nearest approach is made, to the Cossonide type of Rhynchophora. The front part of the liead is more distinctly pro¬ longed into a short stout beak, which is obliquely excavated on the side, for the reception of the scape of the antennae. The funiculus consists of 7 distinct joints, of which the 1st is but little larger than the 2d; from the 2d to the 7th they are gradually a little wider; the club is small, oval, not compressed, distinctly annulate ; the basal half is shining and nearly glabrous ; the prosternum is deeply excavated for the re¬ ception of the head ; the tibiae are broadly dilated and serrate; the joints of the tarsi 1 — 3 are equal in length, the 3d emarginate, or bilobed, the 4th equal to the two preceding united, not much thick¬ ened at the tip. The 1st and 5th ventral segments are conspicuously longer than the intermediate ones, and the sutures are straight, and very deeply impressed. The chief character relied on by Dr. Zimmermann for the distinction of his genus HI. H. EDWARDS. Under side of primaries pale fulvous, inclining to yellow on the costa and hind margin ; an irregular black patch on middle of costa, another near apex, a third within the inner angle and a fourth on mid¬ dle of inner margin ; a few indistinct lines near base caused by the transparency of the wing; apex yellow and a yellow patch on middle of hind margin ; a mai’ginal series of fine crenated brown lines, a second beyond that, distinct only at the apex. Secondaries purple-grey (or pearly-grey in some specimens) over rather more than the basal third and broadly along hind margin, leav¬ ing between a submarginal band limited on either side by a delicate crenated brown line that crosses the entire wing ; this band is yellowish, clouded at the costal edge and in the middle by brown ; a row of spots or points along the middle of the band, corresponding to the spots of upper surface, obsolete at outer extremity; hind margin bordered by a fine brown crenated line, above which is a second, (which is the outer edge of the submarginal band) the spaces between the two being lunu- lar; at anal angle the purple shade gives place to yellowish; the mid¬ dle crescents clouded by the brown shade that obscures the band ; the basal portion of the wing reticulated with fine brown lines where¬ of the outer ones being most regular form a second band across the wing; next the .base the lines are irregularly placed; towards costa and about the base the purple shade a little replaced with yellowish. Body above black, covered with fulvous hairs; below white; palpi white; antennae black above, whitish below; annulated with white; club black above, fulvous below. Female. 1.7 inch; a shade paler than the male; similarly marked. Found from New York to Louisiana, and hitherto considered as a variety of Tharos , from which it is readily distinguishable by the pur¬ ple or pearly hue of the under side of secondaries. Tharos is one of our many species about which much confusion has existed, several dis¬ tinct forms being by various authors considered to be included within the limits of this species. In 18G4 I separated M. Phaon , (YVoc. Eat. Soc. Phila.,) and Mr. Reakirt has since described Batesii. To this may be added Marcia , above described. Boisduval aud Leconte in Lep. d’ Amer. page 170, regard Tharos of Cramer, pi. 169, and Tharos of Drury, Yol. 1, pi. 20, as identical aud describe aud figure what they consider the type. The figure of the male and the description correspond, viz : “the under side (of sec¬ ondaries) is of an ochrey-yellow with a great number of undulating ferruginous lines, a brown border that reaches neither angle, marked AMERICAN LEPIDOPTERA. 209 by a yellow lunular spot.” Subsequently they add, “ we possess indi¬ viduals which we regard as varieties, of which the upper wings are black with some fulvous spots and a transverse macular band of same color. Beneath, the inferior wings are entirely without the brown border ; the superiors have likewise a part of the border wanting.” This I believe to refer to M. Batesii , and the figure of the female in the plate seems to represent that species.. In his paper on the Lepidoptera of California in Ann. Soc. Ent. de Ft •ance, 1852, Dr. Boisduval makes a distinction between Tharos , of Cra¬ mer and that of Drury, which he calls Pulchella , and erroneously says is to be found throughout California. Drury’s figure represents the upper surface as nearly black, like Batesii , but gives the under side of second¬ aries as having a white crescent and russet markings, and therein dif¬ fers from Batesii. In the text, evidently two or three species are con¬ fused, the description of upper side applying either to Tharos of Cra¬ mer or to Batesii , or to Marcia. The description of under side of pri¬ maries is applicable to either; of secondaries, it says, “very pale clay colors, with a cloud in the middle of the external edge of a reddish- brown, where (in some) is a silver crescent.” This relates alone to Tharos as described in Boisduval and Leconte and referred to Cramer. Cramer’s figure is not reliable and indeed is worthless, but as Boisdu¬ val has adopted his name and correctly figured and described one of the forms under it, it would not now be questioned. But the name of Pulchella is not specially applicable to any of our species, if Drury’s figure and description is to guide us. I have found Marcia common ou the Kanawha Biver, W. Va., in June. Batesii is of earlier flight and rather rare in that region. Tiiecla Ontario, n. sp. Male. Expands 1.1 inch. Upper side dark brown, color of T. Acadica ; on costal margin of primaries a large smooth oval spot; secondaries have a single tail and a very slight projection at extremity of second median nervule, as in Acadica ; from the base of the tail a faint white line extends along the margin to anal angle; at this angle a few scales of fulvous; between the first aud second median nervules an indistinct marginal dark spot above which are a few fulvous scales in crescent form ; tail black, tip¬ ped with white; fringe of both wings fuscous, next before the tail wdiite, beyond it, black at extremity, white next the margin; seconda¬ ries more produced at anal angle and less rounded than Acadica. Under side uniform light brown, color of T. Calanus ( falacer of 210 WM. IT. EDWARDS. Godart and Harris); across the disk of primaries a nearly straight, narrow band of dark brown .spots, very narrowly edged without by white; this band is continuous except that the two spots in the second and third median interspaces are slightly lunulate and separated ; par¬ allel to the margin is a second band of faint spots, of dark brown, nearly obsolete at each extremity ; on the inner edge of the three or four middle and most distinct of these spots are a few white scales, scarcely noticeable without a glass. Secondaries have a discal row of spots like those of primaries, but separated, forming a nearly straight line (the two middle spots only being outside the line) from the costa to a point just above the black space that surmounts the blue patch, then turning towards abdominal margin in a zigzag course forming the letter W, the last limb of which is the longer and reaches the extreme margin ; hind margin edged by a fine whitish line and bordered by a row of spots occupying the inter¬ spaces, each of which is edged above with a curved black line on which is a second bluish-white; the four spots next apex almost obsolete, merely showing a darker tinge than the ground color, and on these the black crescents are not distinct and the white line is represented by a few scales only ; the fifth spot a shade darker than the preceeding and edged above with a narrow patch of orange-red; the sixth is black with a broad red arch between it and the black line; beyond the tail a large patch of blue scales on a black ground which it does not wholly cover, leaving above the blue a small black spot on which are a few red scales; at the angle a rounded black spot narrowly edged above with white, between which and the black and white lines, which here are not crescent, is a red space. Body above fuscous, beneath, abdomen ashy-brown, thorax, blue-grey; legs white aud black ; palpi white tipped with black ; antenna; annula- ted black and white ; club black tipped with ferruginous. From a single specimen taken by Mr. E. B. Heed, of London, Can¬ ada, at Port Stanley, Ontario, in July, 1808. This species is allied to T. humuli, Harris, ( Hyperici Bois. and Lee.), but differs in several respects ; especially in the color of under surface, in the absence of a fulvous border to the discal lines in each wing, in the couspicious blue patch and red and black submarginal crescents ; the tails of humuli have twice the length also, the shorter of the two being twice as long as the longest in the present species, while in the latter the second tail is a mere point. A figure of T. Ontario will be given in the “Butterflies of North America.” AMERICAN HYMENOPTERA. 211 Catalogue of the described TENTHREDINIDiE and TJRQCERID2E of North America. BY EDWARD NORTON.

The under wings have the lanceolate cell extending to the margin of the wing, as in fig. 2 a, and all the outer marginal cells complete in the males; with the females these outer ner- vures are present, but are broken in several places. This insect differs much from the other spe¬ cies of Strongylog aster in its antennae, its short¬ ened abdomen, and in its under wing lanceolate cell, which in this genus, as well as Allantus and Tenthredo, is formed as in fig. 1 a. The cell is usually shorter in Selandria , Macrophya and Taxonus and does not reach the cross nervure of the brachial cell above. It differs from Peri- neura , Hartig, in having its upper wing lanceo¬ late cell with an oblique cross-line, and its un¬ der wing with an inner and outer apical cell. Fig. 1.

AMERICAN COLEOPTERA. 243 Synonymical notes on COLEOPTERA of the United States, with descriptions of new species, from the MSS. of the late Dr. C. Zimmermann. EDITED BT JOHN L. LECONTE, M. D. CARABIDJE. 1. Metabletus borealis Zim. — Long. 1J lin. Black, very similar to M. ameri- canus, but easily distinguished by the jjrothorax, which is transversely quad¬ rate, only slightly narrowed behind, with broadly reflexed hind angles. — Lake Superior. [Dr. Zimmermann united with Metabletus both Apristus and Blech- rus , with the following remarks :] “The fundamental character of generic similarity, resemblance in form of body, belongs to all species mentioned below, which form a very natural group, easily distinguished from Dromius, with which it was formerly united; of the divisions which may be recognized among these species, some ( Apristus , BJechrus ) have been separated as distinct genera, although they must, by the want of primary generic right (Gat- tungsrechte), as well as by the absence of permanence in the secondary generic characters, fall again into the central group.” [The divisions alluded to above, are then arranged as follows :] A. Head elongated, narrowed behind : a. Elytra scarcely shorter than the abdomen, but slightly truncate.— ■-( Vario- palpus Sol.) b. Elytra shorter than the abdomen. — (Oxoides Sol.) B. Head shorter, not obviously narrowed behind : c. Peduncle of prothorax strongly projecting; elytra rectilinearly trunc¬ ate behind; (emargination of men turn without prominent tooth.) — (Blechrus Schaum ; Bomius Lee.; Microlestes Schmidt-Goebel.) d. Peduncle of prothorax strongly projecting; elytra feebly sinuate at the posterior truncation; (emargination of mentum with prominent tooth.) ( Metabletus Schaum ; Bromoceiyx Schmidt-Goebel ; Syntomus Hope.) e. Peduncle of prothorax very feebly prominent; tip of elytra scarcely si¬ nuate; (emargination of mentum with a prominent tooth.) — Apristus Chaud. 2. Cymindis brevipennis Zimm. — Long. 4 — 4J lin. Ferruginous, elytra dark brown, with greenish metallic gloss; palpi, antennae, legs, a humeral spot, and the side margin of the elytra testaceous yellow. Head and prothorax thickly and coarsely punctured ; the latter cordate, with broadly reflexed side margin, and almost rectangular slightly projecting hind angles. Elytra unusually short, slightly convex, with punctured striae, intervals with double rows of punc¬ tures ; the 3rd interval with scarcely discernable dorsal punctures. — Kansas. LeConte (Ann. Lyc. Nat. Hist. N. York, iv, 186) bus erroneously considered this species as C. cribricollis Dej. 244 JOHN L. LE CONTE, M. D. [I learn by a recent letter from Baron Chaudoir that this species, from the vicinity of the Rocky Mountains, is not cribricoUis Dej. as I formerly regarded it, hut one thus far unnamed. Dejean’s species is identical with 0. marginata Kirby and reflexa Lee., and occurs in the most northern part of the United States and in Canada.] 3. Platynus rubripes Zimm. — Long. 3— 3£ lin. Of the form of P. punctifor- mis, but smaller, with large deep basal impressions of the prothorax, and yellow- ferruginous legs. Shining black, smooth ; palpi and antennae testaceous, basal joint of the latter yellowish-red. Prothorax almost as long as wide, with round¬ ed hind-angles, near which the broad basal impressions are marked with a small deep fovea. Elytra formed and sculptured as in P. punctiformis, but nar¬ rower towards the base, so that the humeri are more angular, while in puncti¬ formis they are rounded. This insect, omitted by LeConte in his Synopsis of Platyni, or per¬ haps confused with punctiformis, must he properly received as a separ¬ ate species. It occurs, but not frequently, in the region north of the Potomac, while the species just named is very abundant in the South¬ ern States. [The had condition of the specimens in my collection prevented me from describing this species as distinct, when I wrote the Syn¬ opsis.] 4. Platynus lenis, (Ag. lenurn Dej.)=P. retractus Lee. [The arrangement of the species of Platynus for which, on account of the confusion in the names previously used. Dr. Zimmermanu proposed the name Psilopodius , seems so far superior in some respects to that adopted by me, that although I have not had leisure to test it by a re-examination of all my species, I think it well worthy of being presented :] A.

First four joints of hind and middle tarsi with lateral grooves: a. Elytra with 3 dorsal punctures. — ( funebris Lee.) b. Elytra with 2 dorsal punctures. — ( albipes of Europe.) The species of division B — d have for the most part only lateral grooves on the basal joints, though sometimes the middle groove is also present. By this character and by the form of the claws, aided by the color of the elytra, they may be grouped as follows : Series I. Tarsi with a medial groove; claws regularly curved : Group A. First three joints of middle and hind tarsi with lateral. grooves : a. Elytra with three dorsal punctures. — ( subcordatus Lee.) Series II. Tarsi without medial groove; claws regularly curved ; Group A. First three joints of middle and hind tarsi with lateral grooves; elytra margined with yellow: a. Elytra with 4 or more dorsal punctures. — ( maculicollis , variolatus.) b. Elytra with only 3 dorsal punctures. — ( marginatus of Europe.) Group B. First three joints of middle and hind tarsi with lateral grooves, elytra without yellow margin : a. Elytra with 4 or more foveae on the 3rd interval. — (8 -punctatus.) b.

Elytra with fovece on the third interval. — ( bembidioidea , stigmosns.) The species of division B — e have but three dorsal punctures, which in general are not connected with the striae, but stand free upon the 3rd interval ; but few are thus far known, which may be grouped thus : Series I. Tarsi without medial groove: Group A. Tarsi without distinct lateral grooves. — ( limbatus ■) Group B. First three joints of middle and hind tarsi with fine lateral grooves. — ( punctiformis , rubripes Zimm. ) Division B — f presents no special characters for grouping the spe¬ cies, of which as r-uginosus and striatopunctatus may be taken as exam¬ ples. In the species of C — g the lateral grooves of the first three joints of the middle and liiud tarsi are visible, but finer than usual; according to the form of the prothorax the following groups are indicated : a. Prothorax nearly quadrate, or feebly cordate, with distinct though obtuse hind angles. — ( micans &c. of Europe.) b. Prothorax rounded oval, without distinct hind angles. — ( lenis , picipennis, lutulentus.) DiCiELUS. — The species may be arranged as follows : A. Upper surface violet, or copper colored : a.

Sp. Gen. iii, 283. — LeConte has twice mistaken this species: 1st he placed it (Ann. Lyc. iv, 336) as synonymous with caudicalis Say, which is an Ifypherpes, and afterwards, (Journ. Ac. Nat. Sc. Phil. 2nd, ii, 243) as luctuosa Dej, which is equivalent to P. abjectus Lee. [The name carbonaria has been inadvertently omitted in my List, and it is really a synonym of muta Say, as determined by Baron Chau- doir (vide infra); the confusion in my mind with regard to F. luctuosa Dej., which as I was afterwards informed by Baron Chaudoir (Say’s Entom. Writings, ed. Lee. ii. 480) is the same as my P. abjectus , re¬ sulted from the fact that the description of Dejean will apply equally to both species ; carbonaria cannot be referred to the present species since the description states that the outer stria of the basal impression is wanting; it is in caudicalis short, and very close to the Carina of the angle, which is more distinctly defined than in the smaller species, P. luctuosus. About F. caudicalis Say, I may observe that Dr. Harris gave me specimens of the species under consideration, as having been compared with Say’s type ; moreover the expression “space of the basal angles depressed and punctured,” and the fact that the insect is winged, absolutely forbid the reference of Say’s description to any species of Ilj/pherpes.

The object of the present paper, and of others now in course of pre¬ paration, is to make known the species of Tortricidae inhabiting the United States. The late Dr. Brackenridge Clemens of Easton, Pa., published descriptions of nearly one hundred species, and notices of a few others are to be found in the writings of Dr. T. W. Harris, Dr. A. S. Packard Jr., Dr. Asa Fitch, H. B. Moeschler, aud Mr. Francis Walker in the British Museum List. It will be perceived that the numerous families and genera into which the Tortricidae have been divided by J. F. Stephens, S. Gf. Wilkinson and H. T. Stainton are taken little cognizance of in these papers. Dr. Clemens endeavored to follow the English authors mentioned above, and even added to the number of genera they had described, but his writings expressly state that it was merely for the sake of convenience, and not because of a belief that they had any foundation in nature. In the Proceedings of the Academy of Natural Sciences of Philadelphia, page 360, Aug. I860, he says: ‘‘This group of insects is probably the most difficult, in a systematic point of view, and the least interesting family in the order of Lepidoptera. The impression I have derived from the study of it induces me to believe that it is owing chiefly to the artificial system by which it is at present interpreted, and which I have endeavored to follow in this paper. Numerous families, or so-called families, have been arbitrarily instituted on the most trivial and un¬ tenable characters, some of which are only sexual peculiarities, while ornamentation appears to be a far more important element than struc¬ ture in the diagnoses by which they are characterized. Such an ar¬ rangement possesses a certain amount of convenience, inasmuch as it frequently enables the student or inquirer to limit the probable number of genera to which an insect he may wish to classify may belong. This however, is its total significance, and even in this ^respect it is often de¬ ficient and deceptive. This is a system of convenience and not of na¬ ture, which works on categories of structure and recognizable concep¬ tions or ideas.” It is to be regretted that Dr. Clemens had no access to the works of continental authors, while writing upon this subject. He says in the Proceedings of the Entomological Society of Philadelphia, Yol. v, p. 138, Sept. 1865 : “The ouly work I have that treats of the Tortricina , (34) TRANS. AMEE. ENT. SOC. FEBRUARY, 1869. 262 COLEMAN T. ROBINSON. is Mr. Wilkinson’s British Tortrices, and his generic diagnoses are so peculiarly written, his tables of genera founded on a fanciful compari¬ son of the length of the middle joint of the labial palpi with the api¬ cal joint, that the location of a specimen is very troublesome and diffi¬ cult. At some subsequent day I will review what I have done in this group, as soon as I can obtain types of European genera and thus cor¬ rect the numerous errors I have doubtless committed by describing new generic groups, when genera have been already created into which they could have been received, and of which I have no knowledge.” These were among the last words written by Dr. Clemens on any entomologi¬ cal subject. His death in the prime of life, two years afterwards, de_ prived us forever of one of the most thorough and intelligent students of nature America has produced. A correspondence was commenced with Dr. Clemens shortly before his death, the object of which was to cooperate with him in carrying out the intention mentioned in the paragraph quoted above, and to il¬ lustrate by plates and more detailed descriptions, the species discovered in the mean time. A library of important works on the subject has been accumulated as well as large collections of European and Ameri¬ can specimens. I now, with much diffidence, undertake the task alone, hoping thereby to call the attention of abler systematists to the subject. Leaving the full discussion of generic values and other matters of clas¬ sifications until a future period, I shall endeavor to illustrate the spe¬ cies thus far obsei*ved. Messrs Francis G. Sanborn and Dr. A. S. Packard Jr. have assisted me materially by placing their collections in my hands for study and comparison. TORTRICIDAE. TORTRIX, Treitschke. Tortrix rosaceana. Walker.

I have now described and figured all the North American species known to me of the genus Tortrix as limited by the late authors of con¬ tinental Europe. No attempt has been made in this paper toward a systematic arrangement, as some of the species figured are represented by single specimens which would be rendered unfit for the engraver by any examination of the details of their structure. I hope that the de¬ scriptions with the aid of the plates will render the preservation of such specimens unnecessary. TERAS Treitschke. This very variable genus does not appear to be well represented on this continent. Of the few specimens in collections to which I have had access a large proportion resemble closely varieties of European 280 COLEMAN T.

In all cases where I have not found them absolutely indentical with Euro¬ pean specimens or figures new names are given, as I consider it prefera¬ ble to increase the synonomy rather than leave the varieties undescri¬ bed or wrongly referred.

American Diptera on the golden rod ( Solidago ) have hitherto been described; the history of three of them is complete, as the insect, producing them, has also been described; (. Trypeta solidaginis Fitch, Cecid. solldaginis L\v ; Cec. hirtipes 0. S.); two have been named in anticipation of the discovery of the insect ( Cec. racemicola O. S. and Cecid. carbonifera 0. S.). To this number I can now add three more galls from which T have bred the following insects; Trypeta polita Lw., Asphondylia monacha n. sp. and Cecidomyia anthophila n. sp. These eight galls, produced by Diptera on Solidago , may be classi¬ fied as follows : 1. — Smooth swelling of stem or branch ; Trypeta solidaginis Fitch ; Cecidomyia liirtipcs 0. S. 2. — Accumulation of leaves in consequence of the arrest of growth of stem or branch; Trypeta polita Lw., Cecidomyia solidaginis Lw., Asphondylia monacha n. sp. 3. — Enlargement of bud on flower, amongst the racemes; Cecid. ra¬ cemicola O. S., Cecid. anthophila n. sp. 4 - Hardened spot on the leaves; Cecid. carbonifera 0. S. (The descriptions of the two Trypetse, as well as that of the above mentioned Cecidomyise and their galls, may be found in the first vol¬ ume of the Monographs of North America Diptera). Asphondylia monacha, n. sp. The gall of A. monacha , like that of Cecidomyia solidaginis. consists of an accumulation of leaves upon a stem or branch the growth of which has been stunted by the operation of the insect. Several branch- lets being stunted in this way alongside of each other, form a more or less elongated head, sometimes several inches long, consisting of an ac¬ cumulation of leaves. This head, at least the specimen which I have before me, is more elongated, less stout than the heads of Cec. solida¬ ginis which I have seen. But the principal difference lies in its inner structure. The leaves forming the inner part of the gall of Asph. mo¬ nacha although stunted in their growth, have none of the character¬ istic appearance of the numerous narrow ribbond-like leaves, surround¬ ing a central cell, in the gall of Cec. solidaginis ; (compare Mono¬ graph , etc., 1. c. Tab. 1, f. 9, 10). 300 R. OSTEN SACKEN. These galls, collected by me in September 1867, near Brooklyn, L. I., on Solidago altissima, very soon gave me several specimens of the fly. Asphondylia monacha n. sp. — Nigra, tarsorum basi nivea. Black, basis of the tarsi snow-white. Body blackish, clothed with black hairs (dry and somewhat faded specimens look brownish, with an admixture of yellow hairs); feet with a deep black, ap- pressed pubescence; the short first tarsal joint and the basis of the second are snow-white; knees likewise whitish. Wings clothed with blackish hairs, espe¬ cially dense along the anterior border ; the venation shows nothing extraordin¬ ary, being like that of Cecidomyia or Dip/osis ( Monographs etc., 1, page 174, fig. 1 and 2), that is, it consists of three veins, the last of which is forked; the second vein is nearly straight and ends almost in the middle of the apex of the wing ; the anterior branch of the fork of the third vein is concealed in a fold, running backwards to the root of the wing, which produces the appearance as if there were four longitudinal veins (somewhat like fig. 5 on the above quoted page of the Monographs) ; in order to perceive the real direction of the anterior branch of the fourth vein a very close examination of a denuded wing is necessary. The antennae are 2 — 12 jointed, filiform, pubescent; the joints of the flagel¬ lum are cylindrical, of nearly equal, gradually diminishing length up to the ninth; the tenth is smaller than the ninth ; the two last joints, the eleventh and twelfth, taken together are about equal to the tenth in length; they are short, button shaped. Halters black. I have two male and a female specimens before me, which I regret not to have described when they were alive; I merely took a note rela¬ tive to the structure of the antenure of one of the specimens, but forgot to observe its sex. As described by me, the antenna of A. monaclia is exactly like that of A. sarothamni 9 figured by Winnertz ( Linnsea Ento- mologica Tab- iv, f. 2 &); the antennae of the male of this species have one joint more, that is, 2 + 13 joints. Owing to the present dry condition of my specimens I am unable to say whether the same differ¬ ence exists in A. monacha. My female specimen shows, at the end of the body, a long, yellowish, almost cylindrical ovipositor, nearly like that of A. sarothamni, figured by Winnertz (1. c. Tab. 1, f. 15). But it does not show the long, needle-shaped, horny organ which appears on Mr. W. figure as protruding beyond the cylindrical joint of the ovi¬ positor, and is also mentioned in the description. The character men¬ tioned by Mr. Winnertz (1. c. p. 185) as belonging to Asphondylia, that “the second longitudinal vein reaches the margin beyond the apex of the wing,” does not seem to be essential to the genus, as it is not to be found in A. monacha. The pupa, immediately before the exclusion of the fly, extricates it¬ self from the gall and frills to the ground. In this Asphondylia mona¬ cha again differs from (dec . solid aginis ; the extremely light and fra¬ gile pupa case of the latter remains hanging on the outside of the gall AMERICAN DIPTERA. 301 after the escape of the insect. The pupa case of A. monacha has a much harder consistency, has two contiguous, short, subconical, pointed projections at the top of the head, (exactly like the pupa of a A. saro- tharnni figured by Mr. Winnertz 1. c. Tab. 1, f. (5.) The dorsal seg¬ ments of the abdomen are covered in the middle with a number of small points; the last segment, at the tip, has a crown of such points. As far as I know, six european Asphondylire are described; most of them develop in the buds of flowers, or produce galls. In the Mono¬ graphs of N. A. Diptera. Vol. 1, p. 7, Mr. Loew made the suggestion that “ Cec. grossularise Fitch, ought, as it seems, to be referred to the genus AsphondyUa.’'1 But when he made this statement, he could hardly have seen I)r. Fitch’s description of the antennae of this species, the joints of which are “ separated by hyaline pedicels one third as long as the joints, which are short cylindrical, with rounded ends, their length scarcely more than double their breadth.” It results from this description that Cec. grossularise Fitch cannot be an AsphondyUa , and that A. monacha is the first N. A. species hitherto described. But I possess in my collection an undescribed species communicated to me by Mr. Walsh some time ago under the name of Cec id. helian- thi globulus Walsh in 1 itt. , which is an AsphondyUa. The pupa has the same coriaceous, hard consistency as that of A. monacha ; the dor¬ sal segments of the abdomen of the pupa are likewise muricate and the end of the abdomen has a crown of little spines; the two horny fron¬ tal projections are likewise contiguous, only much smaller than those of the pupa of A. monacha. It results from the foregoing that, as far as observed, the characters of AsphondyUa consist principally in the structure of the antennae (cylindrical, elongated, sessile or nearly sessile joints, pubescent, with¬ out verticils; their number the same, or nearly the same in both sexes), and in the elongated ovipositor of the female ; to which may be added the structure of the pupa-case, which is of a rather tough consistency, is muricate on the dorsal segments of the abdomen and has the frontal pointed projections contiguous , and not remote as in many other Ceci- domyidse. Trypeta polita, Loew. I have been fortunate enough to trace the history of this pretty fly, described and figured in the Monographs , etc. Yol. 1, page 77, Tab. II, fig. 12. It produces galls, not unlike small Brussels sprouts in appear¬ ance, caused by the arrest of the growth of the side branches of Soli- dago altissima. The accumulation of leaves produced by this stunting 302 R. OSTEN SACKEN. is a little over half an inch long, sometimes much smaller; on the in¬ side there is a comparatively large hollow space, containing the pupa. Some of the galls were nearly sessile on the central stalk of the plant; in other cases, the branch had grown an inch or two before being de¬ formed by the gall. In some cases from four to six galls occupied the end of the stalk. The flies after escaping leave a whitish, transparent pupa-case inside of the gall. I found these galls quite frequently near New London Conn., and in the environs of Brooklyn. L. I. As sev¬ eral of the specimens collected by me produced flies about the middle of September and as T. polita, if I remember right, is frequently found in the spring and in summer, the question remains to be solved whether the flies hybernate, or whether some of them remain quiescent within the pupa until the next season ? Cecidomyia antiiophila n. sp. Among the racemes of Solidago I observed (in September 1867, near Brooklyn, L. I.) that some of the flowerlets were deformed into a gall, somewhat analogous to that of Cecid. racemicola O. S. ( Mono¬ graph s, Yol. 1, p. 196), on account of the mode of its occurrence, but different in structure. The new gall is elongated-conical, blunt at the end, about 0.25 — 0.3 of an inch long; the basis about 0.1 broad; the surface is pale green, covered with a white down ; the inside of the gall is hollow, divided in two compartments by a delicate, somewhat fun¬ nel-shaped membrane, placed about the middle of the cavity, point up¬ wards. At the bottom of the lower compartment, that is, at the lower and broader end of the gall, the small, whitish larva may be found ; it shows no sign of a breast-bone, except two, exceedingly minute black dots, visible only under a very strong lens. Towards the end of Sep¬ tember, numerous Cecidomyia: were obtained from these galls. Un¬ fortunately, l have preserved only a few specimens, all males. Thus I am unable to state, whether the antennal joints in the female are pe- dicelled, as in the male, or sessile. The structure of the antennae ren¬ ders it apparent that this species belongs to the genus Cecidomyia , in the narrower sense, and not to Diplosis. Cecidomyia anthophila n. sp. 'J, . — The pale brown antennae count 2 -f- 19 joints ;® those of the flagellum are nearly as long as their pedicels ; the length of each joint is nearly double of its breadth ; the shape of the single joints is some¬ what square (otherwise the flagellum is not unlike Tab. I, f. 5 of Monographs, etc. Yol. I). Thorax pale brown, shining above; a spot on the humeri is pale yel¬ lowish; stripes hardly indicated by rows of hairs; pleurae brownish in front, -* 1 1 must be borne in mind that the number of joints of the flagellum in Ce¬ cidomyia seusu str. is often not quite constant in the same species.

Abdomen brown, hairy; male genitals yellowish-brown. Feet brownish, underside with a whitish re¬ flection ; (when denuded, the feet appear pale). The first joint of the tarsi, as usual, is very short; the second is about equal in length to the three following taken together ; (the relation of these four joints is about as follows : fii. 2j. 1 ; it is nearly the same on all feet.) The wings are clothed with grayish hairs ; the second longitudinal vein is very gently arcuated; no perceptible cross-vein between the first and the second longitudinal veins.

Genus NEOPJIASIA, Belir. Larva ignota. Imago ; caput globuliforme, oculi proforma thoracis magni promi- nentes; palpi strictiusculi, capite longiores, compressi, hirsuti, an- tennse mediocres iu elavam fusiformem desinentes, abdomen gracile alis inferioribus brevius, aim elongatm tenerrimae, eellula discoidalis in me- diam alam porrecta. Alarum anticarum angulus superior acutiusculus. This Genus forms a very natural passage from Pontia to Pier is. From Pontia it differs by the shape of the wing; from Pieris by its gauze-like substance, by the shape and proportions of the head and the slenderness of thorax and abdomen. The shape and position of the discoidal cell separates Neophasia from Leucophasia. I know of two species belonging to this genus, both of them inhabi¬ tants of the pine forest region of the mountain chains parallel to the coast of the Pacific. 1. N. Menapia. ( Pieris menapia , Felder) is found on a certain elevation of the Sierra Nevada. Of its habits, I only know that it is found in pine forests. Mr. Lorquin, well known by his scientific trav¬ els, ventures the opinion that the caterpillar feeds on some coniferous tree, a supposition, that, notwithstanding the unusual food for a Pierid larva, is not altogether so improbable as it appears at first, as, I, my¬ self have found the larva of a true Pieris , in South Australia, on a species of Loranthus. 304 HERMAN BEIIR, M. D. 2. N. Terlooii. nov. spec. — Alae anticae longitudinaliter dimi- diatae, dimidium superius nigrum, fascia maculari repanda alba iutersec- tum, dimidium inferius cum alis posticis album. It is not necessary to point out how very different the coloration of this species is from Menapia. It was caught by Baron Terloo in the pine forest region of the Sierra Madre in a cold, inhospitable region. It was fluttering at a considerable height between the fronds of the coni¬ ferous trees and finally alighted on a Lorauthus, the only plant in flow¬ er in the neighborhood. Antiiocaris EmvARDSli, nov. sp. — Ausonoidi similis, sed alis an- ticis repandiusculis, posticis subtus lilacinis obscurius undulato-mar- moratis, ad marginem anteriorem macula Candida signatis. This flue species is very different from all the other Californian spe¬ cies and the most considerable in size. The line of the outer margin of the forewing is somewhat that of Genutia, but the general shape is more like that of Sara and of Cardamines. The under side of the hind wings approaches in its markings some African species; it is of a silky, shining, lilac color marbled by short undulated lines of a darker hue with a reflex of olive color, that also tints the disk and anterior margin. This tint is interrupted on the anterior margin, some small patches of pure white and a conspicuous stripe extending from the sub¬ costal vein to the middle of discoidal cell. I possessonly two females, so that I am not certain whether the male has an orange tip or not. Both specimens are from Downieville. Anthocaris Cooperii, nov. sp. — Saree similis sed macula auran- tiaca in alis anticis maris nec marginem exteriorem nec posteriorem at- tingit ; foeminae alae si umbrarn fulvescentem exemeris a margine anteriori orieute macula omnino destitute sunt. Alae posticae subtus fas- ciis liete viridibus irregularibus sed cohaerentibus, neque ut in Sara , punctulatis ornatae. Smaller than Sara. I received several specimens of both sexes by the kindness of Dr. Cooper, who collected them in San Diego. The male seems not to vary either in size or markings but the female varies in both, and in one individual approached very near Lanceolata. Even the outline of the wings is not constant in the three specimens I pos¬ sess of the female.

In this species the antennae are relatively short; the “club” long and narrow. The head is well sized, held free from the thorax. The labial palpi are long, well advanced beyond the front, divaricate, the elongated third article slender and thinly scaled, curving slightly up¬ wards. The thorax is large and full. The legs unarmed and thinly scaled, moderate, the anterior pair more slender and shorter than the middle and hind pairs. The wings are entire and ample; primaries triangulate; secondaries rounded. The primaries are slightly arcuate along the costa, straight along internal margin, rounded along the full external margin which retires slightly before the determinate internal angle. The anterior wing is dilated at its outer third ; the median nervules well separated. The primaries have eleven veins or veinlets. The costal vein is simple, joining the costa a little beyond the middle. The subcostal throws off the 1st, 2nd and 3rd s. c. veinlets on the cos¬ tal margin, these veinlets approximate and parallel in their course. The 3rd s. c. is very slightly further removed from the 2nd than this latter from the 1st, and is furcate before the margin, sending out the 4th s. c. outwardly to the apex of the wing.' The 5th s. c. joins the ex¬ ternal margin and is widely separate from the 4th. The cell is not closed ; the independent vein simple and straight.’- Three median vein- lets, the 1st and 2nd springing from one point, divaricate. The internal vein is straight. The secondaries have nine veins or veinlets. The 308 AUG. R. GROTE. costal veiu is abruptly bent upwardly at base, thence following the cos¬ tal edge to the apex of the wing. The subcostal vein is two and the median three branched. The cell is open; the independent slight. The submedian and internal veins are simple. The abdomen is short¬ er than the internal margin of the secondaries. I take the Hesperia tarquinius of Fabricius (the Polyommatus cratae- gi of Boisduval and Leconte) as the type of the genus Feniseca. Con¬ generic with Fen. tarquinius, and a second species of the genus, is Fen. porsenna, considering Mr. Scudder’s Polyommatus porsenna from New England in reality a distinct species. I have specimens of F. tarquin¬ ius from Georgia and, on comparison, I cannot distinguish specifically between them and material from Pennsylvania which I refer to this same species. Above, the colors and ornamentation of Feniseca tarquinius some¬ what resemble those of certain species of Hesperia, while reminding us more strongly perhaps of Thecla (favonius), with which latter genus its structural affinities lie. - o - On a new Genus of UGCTUIDAE allied to DY0P8, with remarks on certain species of AGROTIS. BY A. R. GROTE. To a genus indicated, but not named, by Guenee, and for which the term Litoprosopus is proposed, belong three species of Noctuidae with ocellated secondaries allied to the South American Dyops, but distinct¬ ively characterized by the smoothly and closely scaled elongate and subspatulate third article of the labial palpi. In the South American Dyops ocellata, and D. oculigera, the labial palpi are given as “a 3e article court, conique, confondu avec le prece¬ dent” (Noct. Vol. 2, p. 283). It is noteworthy that while M. Guenee says: “Peut-etre faudra-t-il faire deux genres des trois especes qui com- posent celui-ci (c. a. d. le genre Dyops)”, and while the genus is divi¬ ded by this Author into two Groups, no remark is made on the differ¬ ences of palpal structure which I suppose induced the division of the Genus into “Groupes,” although, indeed, no reason at all is given in Vol. VI of the Species General des Lepidopteres for the observation (as above cited) or the procedure. The specific distinctiveness of all the three species described by Au¬ thors and here enumerated, is assumed but not assured. The species described by Guenee as Dyops Hatuey , does not indeed seem to be the Noctua Hatuey of Prof. Poey, as suggested by Mr. Walker, who ap- AMERICAN LEPIDOrTERA. 309 pears to have had the true Noctua Hatuey Poey, before him and to have correctly separated Dyops confligens Walk. (Dyops Hatuey Guenee?) from that species. A single species inhabits our Territory and is known to me in Nature. This is Dyops futilis G. & R., from Florida. In the representation of this species only one palpus is indicated by the Artist; an error caused by the fact that but one remained on the only specimen of the species known, after its dissectional study. As remark¬ ed at the time of its description, the presence in Florida of a species congeneric with West Indian forms, shows the near relationship of the Lepidopterological faunae of the Peninsula and the West Indies.

(1. c.). On pages 524 to 528 in the third Volume of the Proceedings of the Entomological Society of Philadelphia, I described four species of Am¬ erican Noctuidae under the genus Noctua as amended by Guenee in the Species General des Lepidopteres. The genus is not distinguished by recent authorities from Agrotis and I now refer these species to Treitschke’s genus. The four species are: Agrotis brunneicollis 1. c., Plate 5, fig. 5; Agr. cupida, 1. c., Plate 5, fig. 7; Agr. alternata, 1. c., Plate 5, fig. 8; Agr. vittifrons, 1. c., Plate 5, fig. 6. I have elsewhere erroneously referred the Noctua lubricans of Guenee as identical with our common Agrotis clandestina ( Noctua clandestina Harris), a species found under the loose bark of trees in company with Amphipyra. A. clandestina is nearly allied to Agr. brunneicollis, while M. Guenee’s species is totally different in form from these, and hardly belongs to this genus. I discovered my mistake during a visit to M. Guenee at Chateaudun, and afterwards verified this correction by an examination of M. Guenee’s type in London. The deceptive coloration of M. Guenee’s badly drawn figure of N. lubricans, together with points in the description which agreed with A. clandestina, induced my earl¬ ier reference. 310 GROTE & ROBINSON. On the American Butterflies referred to the Genus CHARIS by Doubleday. By A. R. GROTE and C. T. ROBINSON. Doubleday and Hewitson, (Text p. 452,) retain the Genus Charis Hubner Verzeichniss, for a generic group of Erycinidae species belong¬ ing to which have been described under the genus “Nymphidia” or “Nymphidium” by Authors. In the Verzeichniss, Hiibner’s genus is erected for two of Cramer’s species unknown to us in nature. Without specimens of the South American Butterflies referred to Charis by Doubleday and Hewitson, we follow these Authors in associating our two United States species with those referred to Hiibner’s genus, but one of which species was then known to the English Entomologists. These species are C. caenius Doubl. & Heicit. ( Nymphidia pumila Bois & Lee.) and C. borealis ( Nymphidia borealis G. & R.). After giving the characters af the genus Charis, Doubleday & Hew¬ itson remark : “The majority of the species are further distinguished by the hirsute eyes, a character wanting , however, in Ch. caenius and two or three allied species. The last named species is remarkable for being the only butterfly of the family found in the United States (1. c.).” For the group so characterized, and of which our C. caenius is typi¬ cal, we propose the name Calephelis. Judging from figures, indeed, we may conceive that Calephelis is entitled to be received as a distinct genus for which the term may with propriety be used. The following is a synonomy of our tw'o species. CHARIS, Hubner (1816). Nymphidium et Nymphidia Boisduval, Blanchard, Gr. & Rob., (nec Fabricius). Charis Hubner (Verzeichniss); E.

LINTNER. Grapta umbrosa, n. sp. Primaries. — Anterior margin moderately curved toward the tip. sim¬ ilar to comma. Tip never falcated, as in interrogationis. Posterior and interior margins less excavated than in interrogationis. Above fulvous ; basal region deeper; disc not so red as in the other Graptas. Fringe white in £ , except at tips of nervules, where it is brown; in 9 , white in some of the interspaces, and brown interspersed with white in others. Posterior border, with a narrow submarginal band of fulvous, preceded by a connected series of dark brown crescents rather obscurely defined. The row of triangular spots anterior to these, a shade lighter than the disc, with the two next the tip, edged before with black. The seven discal spots are of a less glossy black than in interrogationis. Secondaries. — Tail straight, short, not exceeding three-fourths the length of that of interrogationis. which it equals in breadth; length in £ , one-half greater than in 9 • Above, the disc is purplish black, shading into dark fulvous at the base and at the interior margin. The black spot between the subcostal nervules is not so conspicuous as those of the primaries; that between it and the costal nerve, indistinct or wholly wanting; that lying partly within the discoidal cell and extend¬ ing over the lower nervule of the submedian (which spot is oblong and quite distinct in interrogationis) is small, sometimes geminate, or re¬ duced to a simple dot ; in lieu of the conspicuous triangular black spot at the bifurcation of the submedian in interrogationis , is an obscure shade resting on the upper nervule and above it, and extending nearly to the subcostal nervule. The submarginal row of red crescents which characterizes interrogationis , is here obsolete or limited to three round¬ ed spots at the most between the nervules of the subcostal. Tail and tips of nervules with lilac scales; in interrogationis the entire hind mar¬ gin is bordered with lilac. Beneath in interrogationis, a marked feature is the series of yellow or whitish spots of the primaries, usually eleven in number, nearly square, placed on the basal third of the marginal nervure, joining which and extending to the costal nervure are groups of darker colored yellow scales irregular in outline, but grouped opposite to the above costal spots. In this species, the costal spots are fewer in number, smaller, elongated, occupy but the basal fourth of the costa, and are not so conspicuous as to be a prominent feature; the contiguous yellow scales are not grouped, (41) way, 1869. TRANS. AMER. ENT. SOC. 314 J. A. LINTNER. but are reticulated with the brown of the alternations of the costal spots. Both wings in the % are beautifully and distinctly variegated with light and dark brown; on superiors, a costo-subapical violet shade, and inner margin of inferiors glossed with violet. The 9 , of a duller brown, and less variegated with dark brown on the basal half; the superiors faint¬ ly glossed with violet, the inferiors conspicuously so. A submarginal series of crescents of violet colored scales, forms in the S a connect¬ ed band except at the apex, in the 9 an interrupted one. Before and parallel to this in the S , the inferiors have a dark brown band extend¬ ing from the anal to nearly the anterior angle, contracted centrally and at its extremities. Within this baud, between the nervules, is a row of rounded spots of lighter brown, pu pilled with black; these spots, but without the enclosing band, are better defined and more distinctly pu- pillated on the primaries. In the 9 > instead of the dark band on the inferiors, there is simply an interruption of the violet shading, in which space are the rounded pupillated spots; on the superiors, the spots are obsolete, but the pupils distinct; in inter rogation is 9 , these pupillated spots do not appear. The silver discal character is similar in outline to that of interrogation is but more delicate, its upper portion being sometimes divided in two parts.

Described from four % , nine 9 • It is not a little singular that this species should for so long a time, have escaped detection, but the probable reason may be found in its comparatively rare occurrence preventing the bringing together of suf¬ ficient numbers to show the constancy of its characteristic features. Its marked difference of color has long been known, and had lent to it in ordinary reference, the designation of ‘-the black variety.” Harris in 1841 in^his Report on the Insects of Massachusetts, refers to it in his description of inter rogationis thus : “hind wings in the male most often black above, except at the base, and sometimes of this color in the other sex also.” The occurrence of both sexes, afforded sufficient evi¬ dence of its not being a sexual variety, which it was thought by many to be, and its association with inter royationis in New England, New York and elsewhere, proved it not to be a casual result of local influen¬ ces. It does not appear to have been particularly described even as a variety. The figures of inter royationis of Cramer and, of Sm.— Abb., represent the posterior half of the secondaries black merging into dark fulvous, but these are probably only exaggerations of coloring, for the outline of the wings in both cases, is that of interrogation^. Were AMERICAN LEPIDOPTERA. 315 they faithful representations, they would indicate a passing of the one style of coloration into the other, which intermediate grades have nev¬ er cotne under our observation. In addition to the black wings of umbrosa , there are the marked differences of color as compared with the species from which we sepa¬ rate it, of the duller shade of the anteriors as above described, and a less degree of blackness of the spots. There is also a translucency of the wings, which usually permits the silver character of the under sur¬ face to be seen from above. This translucency is very noticeable when the insect is held between the eye and the light, when, also, the obso¬ leteness of the spots of the inferiors is favorably shown, in the almost immaculate appearance of the wings. But if these differences are of questionable specific importance, con¬ clusive evidence of the distinctness of our two species is afforded in the shape of the wings, viz., in the curve of the costo-apical margin of the primaries, in the degree of excavation of their posterior and interior margins and in the length of the tails. Placed side by side, these feat¬ ures will at once strike the eye, and so marked and constant are they, that from comparison of outline alone, the species can be determined. There is also a difference in their sizes, — the expanse of Interrogation is being in the % 2.50, 9 2.75 inches, which exceeds umbrosa by .25 inch. Additional confirmation of the validity of this species, may be found in the circumstances under which it first was brought to my observation. During the first week of July 18G1, there were brought to me at Scho¬ harie, fourteen larvae and chrysalides taken from or very near a garden hop-vine, which, from the casual notice given them, were presumed to be those of interrogationis. The larvae were mature, and in a day or two entered their pupal state. The imagines emerging in about twelve days, proved, to my surprise, to be every one of the “black variety” — three males and eleven females. About the middle of July, several other seemingly identical larvae were taken by me from hop-vines, which emerging the last of the month, gave the ordinary interrogationis. Impressed with a belief in the specific difference of the “black variety” I endeavored to ascertain its larva, and to this end, collected on Aug. 10th two chrysalides, and twenty larvae varying from one half-inch in length to nearly full size. During the ensuing two weeks many addi¬ tional larva; were taken by me from hop yards, and grouped in four breeding cages, in accordance with coloratioual differences which were observed and noted. Of these differences, in lieu of copying at length the notes then taken, it may suffice at the present to state that they .T. A. LINTNER. 316 presented the following gradations : head ranging from red to a gl >ssy black ; spines of the head, from red at base and black above with white annulations to the branches, to wholly black; spines of extremities, from black below and red above, to wholly red; dorsal spines, from red banded with white, and black tipped, to entirely red; lateral rows of spines, from pale red almost white, to ferruginous; body with postula¬ tions from white to rufous; linings of body, from well defined and con¬ tinuous stripes, to lines simply indicated by interrupted markings. After their transformation to the pupal state, several of the above were found to have fallen victims to their natural enemy Pteromnlu s ranessse Harris. From four chrysalides especially observed, above one hundred of these parasites emerged from each, a few words respecting which. — in illustration of the remarkable development of the sexual in¬ stinct with which we are so frequently presented in the insect world- may not be out of place in this connexion. Escaping from their co¬ coons contained within the chrysalis one or more small holes were eaten by them, usually in the wing-cases, through which they came forth with fully expanded wings and in perfect condition, as rapidly as one could follow another. No sooner had a male made his exit, than he at once sought out and united with the opposite sex, quickly passing with vibra¬ ting wings and antennas from one to another: and so extreme was the ardor impelling them to their unions, that several were observed intent¬ ly watching at the holes through which their companions were to emerge, and instantly appropriating each female as she made her ap¬ pearance. As the result of the above larval collections, about one hundred and ten interrogationis were obtained, and not a single umbrosa. Some mi¬ nor differences of shading were presented, but none sufficient to war¬ rant classification in accordance with the previous larval grouping. The pupa cases from which umbrom emerged, were lain aside for fu¬ ture comparison, but when opened after the lapse of two or three years, they were found to be almost entirely powdered by the destructive Aw- threnus varius Fab. Unless my recollection is much at fault, they were of a delicate purplish cast, quite in contrast with the ferruginous hue of interrogationis ; and with several of the dorsal spines having a notable degree of transparency. The observations above recorded, render it probable that the speci¬ mens of umbrosa obtained, were the progeny of one parent. We may also infer a close larval resemblance to interrogationis* and also a pre- *Mr. Edwards has obtained the larvse in W. Virginia, and reared numbers of AMERICAN LEPIDOPTF.RA. 317 cedence in the time of appearance of the summer brood of the former, of not less than two weeks. Its rarity is shown by the above collections made from different hop yards, as well as by the fact of its falling so very seldom in the hands of the collector. Besides the above speci¬ mens. but one other has ever been taken by me. vSince the preceding pages were written, it has been represented to me that umbrosa is identical with the C. aureum of Fabricius. A care¬ ful examination of the Fabrician descriptions of C. aureum and inter - rogationU has shown me that neither can be regarded as synonymous with nmbrosa ; they are as follows: Papilio N. C-aureum. Fab. Svst. Eut.(1775) p. 506, n. 266. F. X. P. alis rlentato-caudatis, fulvis, ni- gro-macuiatis: posticis subtus C-aureo notatis. Linn. Syst. Nat. ii, 777, 169. Habitat in As;a. Fab. Spec.

From the citations by Fabricius of Linnaeus and Cramer, it appears that his C-aureum was identical or supposed to be the same with the Asiatic species (Chinese, Cramer). This species according to Godart “resembles strongly polychloros on the upper side. The underside of its wings is obscure towards the base, yellowish towards the extremity, with a golden C, or rather silver, on the disc of the inferiors. The up¬ per side of most of the females, presents between the middle and the posterior border, five bluish spots, of which three are on the superior wings and two on the inferiors.” To this species are referable, Papilio Angelica Cramer.

Fabricius has taken the male of this Vanessa for the C-aurcuni of Linnams, and he has made of the female a separate species under the name of Papilio in¬ terrogationis. It has between two, and two and a half inches of breadth. The upper sur¬ face of the superior wings is fulvous, with seven or eight unequal black spots, and the posterior border of an obscure brown. The upper surface of the sec¬ ondaries is of a bluish-black, with the base ferruginous. The under surface of the male is of a wood gray ( gris-bois ) undulated and variegated with brown ; the under surface of the female is brown and lightly glossed with whitish-green, especially on the secondaries, on which the disc presents in both sexes, a silver spot in form of an interrogation point or interrupted C. There is besides toward the posterior border of each wing, a row of black points. The body is black a- bove, with some greenish hairs on the thorax; the antennseare brown, with the anterior third of the club whitish and the rest black. From Virginia and the neighboring States. The description in the above paragraph is applicable to umbrosa , and if unqualified, would lead us to refer it to that iusect. The “alis anticis falcatis” however, forbids such a reference, and indicates its having been drawn from some Grapta which as yet has no place in our collections, or, as is more probable, from Abbot’s figure of C-aureum , to which it suspiciously conforms, and which is not our umbrosa. In C-aurcum of Abbot, the primaries are conspicuously falcated; in um¬ brosa, they are uever falcated. The two differ otherwise materially in outline, and in the extent of the black shading of the posterior wings. In the Supplement to vol. ix, Enc. Method., page 819, n. 15 (du- plicata), Godart has amended his interrogationis, so that it conforms to the species as generally accepted at the present day. It is as follows : Vanessa P. interrogationis. . It has from two to two and a half inches breadth. The upper side of the wings is fulvous, with eight or nine unequal black spots on the superiors, and three on the inferiors. The outer margin, which is of a ferruginous more or less in¬ tense, with a transverse series of yellow spots, is bordered exteriorly with ash- blue. The under side is of a blackish brown or dead leaf color, more or less shaded with gray violet, with a silver spot in form of an interrogation point or inter¬ rupted C on the disc of the inferiors. There is also toward the terminal border of the four wings, a transverse row of black points, in part sprinkled with bluish. The female, ordinarily larger than the male, has the origin of the costa be- AMERICAN APT ERA. 319 neath yellow, reticulated with ferruginous. The prolongation of its secondaries is less, and the upper surface of the primaries has nine black spots. From North America. Boisduval and Leconte in their C-aureum , describe the upper side of the inferiors as brown, or of an obscure ferruginous glossed with blu¬ ish green, with the base of a bright ferruginous. The outline of their figure approaches very nearly to that of umbrosa , hut the representa¬ tion of the inferiors differs widely from it, in that less than their inner half along the internal margin is shaded lightly with brown, while the rest of the wing is fulvous and distinctly spotted with black as in in- terrogationis. In their synonymy, they cite C-aureum of Cramer, of Fabricius in Ent. Syst., and of Smith-Abbot; the interrogations of Godart (p. 301, u. 15,) and of Fabricius in Supp. Ent. Syst. From the above it is evident that umbrosa is not the C-aureum of Fabricius, Smith and Abbot, Boisduval and LeConte, or the interroga- tionis of Godart, and is justly entitled to its indication as a new species.

Abdomen long, tapering to a point, with two long anal setae. Legs four in number. Inhabits galls. Movement not rapid. Vasates quadripedes, n. sp. — Body pale yellowish or yellowish-red, elongated to a point behind and terminated by two long slender hairs. Legs directed forward and quite at the anterior extremity, four in number, of the two poste¬ rior pairs, usually found in acarians, there is positively not the slightest trace, even in the most mature specimens; a few hairs are scattered over the legs, the foot appears to be 3-jointed, and is terminated by spines or hairs, tibiae short. Length, 008 — .005 inch. Gall on the upper side of the leaf, by a small pedicel ; form angular, wrinkled and pitted ; at first green, but at length becoming reddish ; the opening beneath is very small and surrounded with a little woolly down ; size variable, say from one-twenty eighth to one-eighth of an inch in diameter. For several years I have observed these galls in the early part of the summer. In the early spring as the leaves begin to expand from the bud, these galls, of very minute size, may be seen forming on the leaf. They appear first on the lower limbs and leaves next to the body of the tree, hence it appears probable that they pass the winter — per¬ haps in the egg-state — on the ground around the tree, and in early 320 HENRY SHIMER, M. D. spring ascend the trunk. As spring passes into summer, I observe many leaves entirely covered with these galls, so that the leaf is dwarfed, curls up and sometimes drops off; a thousand or more galls are some¬ times found on a single leaf. In June I observed in the galls numer¬ ous whitish, translucent eggs, and larvse in abundance; these latter are falciform and very sluggish and without much observable motion. After about two weeks, I saw them in great numbers, crawling about on the leaves, having left the galls to ascend to the body, doubtless for the purpose of establishing new galls; one fine warm da}rs, thousands may be seen on one leaf. Some spider webs on the under side of the leaves serve as traps for these creatures, where they accumulate in such numbers as to give the web a pale reddish color, although the indi¬ vidual acarians are undistinguishable to the naked eye. The galls con¬ tinue during the summer, but later many of them become black and dry and vert/ few of the green ones then contain inhabitants. ACARUS, Linn. Acarus aceris, n. sp. — Imago. Thorax yellowish-brown, legs inclined to same color ; a grayish central line on the back, on each side of which there is some¬ times another line of like color; a number of whitish hairs about as long as the legs are scattered over the body; tarsi 3-jointed, with two claws and a number of hairs ; head rounded, depressed, grey, forehead slightly emarginate. Length of body 0.13 inch; to end of extended forelegs, .02 inch. Papa of various colors, from pale greenish-grey to blackish, with a few com¬ paratively long hairs; legs greyish, translucent; head and anterior part of body pale. The very young larvae are nearly white. Eggs globular, milk-white, 0.04 inch in diameter, placed on under side of the leaf. In June these acarians were quite numerous on the underside of the leaves, and a number of their moulted skins were observed, principally along the veins of the leaf. I sometimes fiud this species on the same leaves in company with Vascites quadripedes. From observing their motions, and from often finding them without any other probable food, I concluded that they feed on the sap. The larvae of Chrysopa and also of some species of Coccinellidte have been observed feeding upon these acarians, and no doubt devour many of the larvae of Ceci- domyia aceris (Trans. Am. Ent. Soc. i. p. 281) which were abundant on the leaves. A It. Carroll , Illinois , April 1st, 1869. AMERICAN IIYMENOPTERA. 321 Catalogue of the described TENTHREDINIDiE and ITR0CERID2E of North America.

Massachusetts, Connecticut. The larva, feeds on the fir leaves. It is 22-footed ; is five to six tenths of an inch long, thickest before the middle, tapering behind ; the head and three anterior pair of legs are black; body pale green, yellowish beneath ; a wide dark green stripe down the back, separated by a paler stripe and two dark green stripes on each side; hinder legs yellowish. It is social in its habits and feeds in companies until ful¬ ly grown, It appears in June and July. The cocoons are oblong oval, rounded at ends, of a tough silk, whitish when new. Length 0.35 inch. They are generally made in August. They are formed on the leaves of the trees on which it feeds and often adhere to them until 326 EDWARD NORTON. the next season. Most of the insects come forth soon after the four¬ teenth day, but some are delayed and appear during the ensuing months. Several hundred specimens bred by myself in Farmington, Conn., came forth mostly in August. If there is a second brood in September, the numbers must be comparitively small, for I have not seen them nor any fresh cocoons late in the season. Dr. Harris states that the cocoons are mostly formed on the ground among the roots of plants. But in the above instances very few were found except upon the branches of trees. When the insect comes forth from the cocoon it cuts a circular piece from on one end as cleanly as with a knife. This sometimes re¬ mains as a sort of lid. This larva is very destructive, remaining for several years in a region and causing the foliage of the fir trees to ap¬ pear brown as if burnt by fire.

Perhaps the crowds of parasites which follow them have destroyed all those left behind. Most of these parasites in leaving the cocoon, burst their way out at the side, cutting a rough passage with their jaws, not clean and sharp like the Lophyrus. 9. L. abdominalis.

Hartig has figured a species upon the pine. Each larva spins for itself a separate case with¬ in the larger webs. It forms a cell in the ground, lined with silk, in which to pass the pupa state. They do not ofteu appear in such numbers as to be very injurious to vegetation. 332 EDWARD NORTON. Table to assist in finding the species. Sec. 1. Anterior tibiae with one side spur.

Head moderate, semiglobose, generally narrower than thorax, eyes somewhat kidney shaped; labrum minute, elongate; maxillae with two lengthened setose lobes, palpi 1 -jointed; labrum produced, its palpi 8-jointed. The prothorax is produced into a short neck, the collar wide, ab¬ ruptly elevated and ungulate before. The metathorax is of two parts, the hinder portion of which has been regarded by some as the basal segment of abdomen. The abdomen long, wide, generally a little thickened toward end, terminating in an elongate point or horn ; irt the female also with an ovipositor coming from beneath the sixth segment and extending beyond the apex of abdomen. The borer which is inclosed between two horny sheaths, is hollow and nearly cyliudical, with lateral grooves and with a separate piece in its lower side, com¬ posed of smaller pieces so arranged as to assist the upper part both as a support and an addition of power. This apparatus has sufficient strength to enable the female to deposit the eggs at some depth in solid timber. It is described and figured fully by Westwood, Hartig and others. Westwood shows an analogy between the saws of the Tenthredinidae and the borers of Urocerus , their general principle being alike, only one is fitted for depositing eggs in tender leaves and stems and the other in solid wood. The larvae are long, cylindical, fleshy grubs, six footed, the terminal segment furnished with a short spine. These larvae bore large holes within the trees, often causing great destruction, especially in pine forests. Mr. Westwood quotes the following statement: Mr. Raddon forwarded to the Entomological Society specimens of U. Juvencus, accompanied by specimens of the wood of a fir tree from Beadley Forest, Wor¬ cestershire, perforated by this insect. Of this tree, twenty feet were so inter¬ sected by the burrows, that it was fit for nothing but firewood ; and being placed in an out house, the perfect insects came out every morning, five, six, or more each day. The females averaged one in twelve for the first six weeks, but after¬ wards became more plentiful and continued to make their appearance until the end of November, females only being produced during the last two or three weeks. (Trans. Ent. Soc. Vol. i, 85, App.) When full grown, the larvae are said to form a slender silken cocoon mixed with chips at the end of their burrows. The pupa greatly re- EDWARD NORTON. 356 sembles the imago, having the limbs laid along the side of the body and breast. When the transformation of the insect take place in the summer the imago is produced in the space of a month, but if the larvae are not full grown uutil autumn, the fly does not appear until the fol¬ lowing summer. These insects are among the largest of the order and from their pow¬ erful flight, range over a wide extent of country, some of our species being found both on the Atlantic and Pacific coasts. As the larvae re¬ main a long time in the wood many of our species have been exported in timber and are now common in Europe. 'fhe sexes vary much in color and size and it is difficult to decide which belong to the same species, unless they are taken together. Much ot interest about the structure of habits of European species may be fouud in the writings of Klug, Dahlbom, Westwood, Hartig,&c. Table to assist in determining species. A.

This may be considered as the American representative of Uroccrm juvencus of Europe, if it is not actually the same species. Mr. Shuckard however, (Mag. Nat. Hist. New. Ser. i, 1837, 630) thinks it a separate species, because in the U. cyancus the terminal mucro in both sexes is more acuminate, and the ovipositor of the female longer ; because it inhabits in plantations side by side, only the American spruce fir (Pinus nigra), while the time of its coming forth is in May and June, after which it is rarely found. The juvencus attacks only the Scotch fir (Pinus sylvestris), and appears toward the end of July and never earlier. Mr. Ingpen ( Trans. Ent. Soc. Lond. ii, 1838, p. lxxxvii) speaks of immense numbers of Si' rex duplex , being bred from lumber which is supposed to have come from Canada, and gives remarks at length on the habit of the insect. Mr. Shuckard names it Sirex du¬ plex ■, on the ground that Fabricius description is not fully determinate, and yet it seems hardly possible, after referring to the original descrip¬ tion, to consider this anything else, as there is no other American spe¬ cies at all like it. 4.

It differs in having the ten basal joints of antennae black, the tergum more or less banded with rufous and only the hinder tibiae and tarsi white-banded. The velvety appear¬ ance of the tergum is owing to the numerous delicate punctures upon its upper surface. 9. U. tricolor. Urocerus tricolor, Provancher, Nat.

It is known to attack the pear, elm, sycamore and maple, but is not often so common as to be injurious to more than isolated trees. It seems probable also that it does not begin upon trees which are en¬ tirely sound. Trcmex obsoletus , Say, may possibly bo the male of T. sericeus , but it is almost precisely like a male of T. colamba from New York.

Wings with two marginal and four submarginal cells, the second and third each with a recurrent nervure, lanceolate cell with straight or slightly oblique cross-line, under wings with two middle cells. Antennas fusiform, five or six-articulate; labial palpi apparently as in Ti • emex . the second joint enlarged and truncate.

This may be considered a subgenus of Tremex , which it resembles precisely in appearance of head and body, but from which the form of the antennae and the dilated tarsi serve to distinguish it. The wings are like those of Urccerus. The form of the antennae is very singular, the third being shorter than the fourth, and the fifth longest, unless it is composed of two joints closely soldered, of which there is some ap¬ pearance. 1.

BY WM. II. EDWARDS. Antiiocaris Reakirtii, n. sp. Male. Expands 1.3 to 1.5 inch. Upper side soiled white, blackish at base; primaries have a large bright orange apical patch, as in Sara , edged on the apex by black as in that species, with serrated black spots also upon the hind margin ; a narrow, slightly bent bar from costa across the arc where it connects with a brown, curved bar from inner angle; costal edge much specked with black scales ; fringe alter¬ nate white and black. Secondaries have three or four patches of black at tips of upper ner- vules ; fringe white, black at ends of nervules. Underside whiter the orange spots reduced and paler; costa of primaries and the whole space on apex and margin outside the orange, densely covered with green patches ; on the arc a bent bar; seconda¬ ries densely and uniformly covered from base to margin by large green patches. Female. Expands 1.7 inch. Same color as male; costal margin slightly specked; the orange spots paler and narrower, reaching from costa to hind margin, not edged by black on inner side, but on outer by a sinuous band, between which and the apical border is a white patch; the band connected with the triangular marginal spots by black nervures; on the arc a tortuous bar, in most cases starting from costal edge ; beneath as in the male, except that costa, margins and secon¬ daries are much less spotted with green. California. From specimens in my own collection and those of Messrs. Reakirt and Henry Edwards, and Dr. Behr. This species has been regarded as a form of Sara. Its distinctness was first pointed out to me by Mr. Reakirt and I have since learned that our Californian lepidopterists had assured themselves of the same thing. The males of the two species much resemble each other on the upper side except in size, Sara expanding more by three or four tenths. But on the under side the present species is much more and differently marked with green. The females differ upon the upper side. I am informed by Mr. Edwards that the yellow form is wholly wanting in the smaller species, while of Sara, at least one-half are decidedly yellow. TRANS. AMEE. ENT. SOC. (48) SEPTEMBER, 1869. 370 WM.

This species is closely allied to M. minuta, Edwards, of which a single male was described in Proc. Acad. Nat. Sci. Phila., 1861, and I am not certain that it may not prove to be the female of that species. Unfortunately the original specimen is not in this country nor accessi¬ ble. I preserved a coarsely executed lithograph of it, from which the female above described differs somewhat, but perhaps not materially. This, or these two species differ from any other North American Melitaeas with which I am acquainted, and belong to the group of which Cinxia ( European ) is the type. AMERICAN LEPIDOPTERA. 373 Grapta Oreas, n. sp. Form of Faitnus. Primaries deeply incised and emarginated; sec¬ ondaries with a prominent rounded tail and a second shorter between this and anal angle. Male. Expands 1.5 inch. Upper side deep red fulvous, color of Faun us, spotted with black. Primaries have a black-brown border on which rests a series of rather large yellowish lunules; a yellowish sub- apical patch beyond which is another of red-brown connecting costa with hind margin; a dark elongated patch from costa covers the arc- in cell two rounded spots and three at right angles to these, on the disk, as in Faun us ; near inner angle a red-brown patch. Secondaries have the border diffuse, enclosing a row of yellowish lunules; a black patch on costa and two on disk; fringes dark brown, yellow in the emarginations. Under side very like Prague, in color dark brown, varied with shades of paler brown or black, slightly grey near apex ; the whole surface covered with fine, abbreviated streaks of darker color ; the basal space scarcely darker than disk and but partially limited on outer edge by a black line; in cell of primaries two elongated dark spots; an extra discal common row of black points; in the incision of primaries and along hind margin of secondaries faint traces of lunules such as charac¬ terise the allied species ; silver spots small, narrow, bent at right angle and pointed at either end. Body brown-fulvous; palpi black below, buff on sides, fulvous above ; antennae brown ; club brown, tip ferruginous. California, from Ur. Belir. This species seems to me sufficiently distinct from our eastern Grap- tas. It connects the two groups, having the form of Faunus and the un¬ der surface of Prague. Under the name O-album , Dr. Behr, in his paper on Californian Lepidoptera, No. IV" (Cal. Acad. Nat. Sci., 1864), des¬ cribes the larva as having “a dimidiate coloration, like that of the Eu¬ ropean O-album, the “fore part being white, the abdominal part yellow,” and as feeding on Urtica. I only know the larva of O-album from pub¬ lished descriptions. Westwood, in Humphrey’s Brit. But., says it is “red in front with the hinder part white” and the figure given corres¬ ponds. Chenu, p. 99, says it is “ reddish-brown with a white dorsal band not covering the four anterior segments, which are sometimes yellow.” By which it would appear that although the coloring of the Californian species is “dimidiate,” there is a difference between it and C -album. 374 WM. n. EDWARDS. The larva of Progne is described by Fitch, 3rd N. Y. Report, 1856, Sect. 142, as grey, “ with a whitish baud on the fore part of each abdo¬ minal segment.” GrAPTA Satyrus, n. sp. Form and size of Comma. Male. Expands 2 inches. Upper side yellow fulvous; primaries have a black brown marginal border, narrower than in Faunus, dilated at apex ; a large subapical brown spot on costa and a second covering the arc; two rounded spots in cell, a third of larger size, near inner margin, and two in median interspaces at right angles with the first; on inner margin near angle a brown patch. Secondaries have the hind margin narrowly bordered by brown, an¬ terior to which is an incomplete line of brown patches; two black spots at origin of median nervules; a large spot on middle of costal margin and another in the disk; fringes dark brown, white in the emargina- tions. Under side marbled in shades of brown, sometimes suffused with vinous; the basal area, occupying half the wings, limited by a common flexuous line, next inside which the color is darkest; in cell of prima¬ ries two long dark spots and some patches of same hue near base of secondaries; the extra-basal space more or less tinted with yellow, much covered with fine, abbreviated, ferruginous streaks; apex of primaries yellow brown, sometimes olivaceous, enclosing three ferruginous points and limited below by a ferruginous line running back from the angle of margin ; subapical patch grey, inclining to white; the marginal in¬ cision bordered by a band which is edged without by a black line, and within by a black bar which encloses a row of narrow olivaceous spots, or lunules; a submarginal row of black points, distinct at the extremities. Secondaries have apex as in primaries ; a submarginal ferruginous arc from tail to anal angle; on the margin above the tail a short border as in the incision of primaries; and below to angle a row of olivaceous lunules between which and the ferruginous arc is a yellow stripe ; a row of black points as on primaries; the silver mark shaped like the letter C or G, large, open, angular below, the lower limb extended and sometimes barbed. Body fulvous above, beneath vinous; legs pule buff, pro-legs vinous; palpi buff below, fulvous at tip and on upper side; antennae dark brown above, buff below; club black, buff at tip. Female. Expands 2.1 inches. Same form and on upper side same color and markings. Beneath nearly a uuiform wood or olivaceous AMERICAN LEPIDOPTERA. 375 brown, with the markings as in male but indistinct and often obsolete; silver mark more open and more slight. Hab. — Rocky Mountains, Colorado. From several males and females in collection of Mr. Reakirt. This species resembles C-album in color and markings of upper sur¬ face, being more spotted, noticeably so, on secondaries, and of a much paler color, than Comma , while it more resembles this last in markings of under side. C-album is however a Protean species, sometimes even in all respects coming very near Faunus. Butin a series of specimens, in my possession, part of which were sent me by Mr. II. W. Bates as exhibiting variations, most differ decidedly from any American form known to me. Our several species of Grapta, though closely allied to each other, keep up their distinctive characters. The series including C-album would run thus: Interroyationis , Umbrosa (Lintner), Comma , Satyrus , C-album , Faunus, and with an interval, that is, in another group, Oreas , Progne , Gracilis. I have never seen reason to believe C-album to be an American species. Authors have applied that name to Comma and to Faunus. As to the Californian species ( Oreas ) above described, if the larva did not appear to be dissimilar, I do not think such a form could be iucluded among the aberrations of even so variable a species as C-album. C.ENON YMPHA KODIAK, 11. Sp. Male. Expands 1.5 inch. Upper side light brown with a grey shade, the whole surface having a silky gloss and appearing either brown or grey according to the point of view; a common whitish bar, caused by the transparency of the wings.

From a single specimen in the collection of Henry Edwards, Esq., of San Francisco. This species differs from all other American Lycae- nidae that I have seen by the absence of decided markings on the un¬ derside, the usual discal row being wanting, and the submarginal scarcely to be distinguished without a glass.

For several years past, especially since 1864, T have made careful observations and study of the Homopterous insects infesting the White Pine ( Pinus strobus , L.) and now submit the following results for the consideration of those who maybe studying the same subject. At the early opening of Spring, there appears on the trunk and branches of the White Pine an insect covered with a wooly-down. This white substance alone attracts the attention, for the insect producing it in such great abundance is quite a minute creature and is not readily seen without the aid of a lens. This downy substance appears most abundantly on young pines, near the ground, early in the spring, just, as the frost leaves the earth, indicating that the insect passes the winter on the ground in the egg-state, and that it is developed by the small amount of heat of early spring. It is now seen more especially on the trunk; some also appear in the axils of the branches. They multiply rapidly and at length, as the summer appears, they become numerous on the young shoots, feasting upon the resinous matter ; they may be found more or less abundant during the season. Within the downy substance this coccus-like insect is found. The pregnant female is of a reddish-brown color, the head not distinct from the body, the back round, much humped, the belly flat, the proboscis carried between the forelegs; the young are pale yellow, quite small, scarcely visible to the naked eye. *■ For the present the synonymy of this species may be given thus: Chernies'? pinicorticis. Coccus 'pinicorticis, Fitch, Trans. N. Y. Reports, ii, g 254 ; N. Y. Agric. Soc. 1859, 871. Chermcs pimfolicc, Fitch, N. Y. Reports, ii, g 207, 185S. As this insect belongs to my family Dcicti/losphairidcc, it is quite probable that, after a more careful study of its relationship with Chermcs in Aphidse, it will be found to be distinct from that genus. Should such prove to be the case, thefol- fowing genus is proposed. PINEUS. Front wing with three simple oblique veins ; hind wing with subcostal or rib-vein forked; wings roofed in repose. Antennae 4 — 5-jointed. Tarsi one- jointed, claws two, with two digituli. Iloney-tubes none. The female secretes a mass of wooly down in which she lays her eggs. 384 HENRY SIIIMER, M. D. I have frequently made careful microscopic examinations of their feet, and was long ago convinced that their arrangement in the Coccus family by Dr. Fitch was a manifest error. Under the microscope I found the foot one-jointed, terminated by two claws, unusually long, aud the digituli terminated by knobs. The following is a description of the winged imago, drawn from a microscopic examination of living specimens: Body short, thick, reddish-brown darkest posteriorly, clothed with a small quantity of downy hair. Abdomen emarginate, segments very apparent ; honey- tubes none. Anterior wing : intercostal space small, but clear ; stigma yellow¬ ish-fuliginous, darkest at its inner end; veins black; rib- vein strong, conspicu¬ ously joining the costal border; oblique veins nearly parallel, the second aris¬ ing from the origin of the stigma, the third — which might be called astigmatic vein — is as straight as the others and arises towards the middle of the stigma, but is aborted at its origin, the first arises about the middle of the subcostal vein, within the stigmatic junction. Posterior wing has only a rib-vein which forks opposite the quite conspi cuous hook. Antennae black, fcur-jointed, the divisions very conspicuous and subequal; first joi nt cylindrical, the others cla- vate ; a short spine on the internal exterior angle of the basal joint, and two at the extremity of the terminal joint ; when viewed from undera high magnify¬ ing power, the joints are composed of several rings, and by carefully examin¬ ing the antenna; from below, the microscope resolves the first joint into two, although four joints will usually be recognized. Legs black, sparsely hairy; feet long, one-jointed, cylindrical, or somewhat tapering at the distal extremity, and terminated by two claws and a few short spines. Length of body .025; length of wing .05 ; breadth of wing .02; length to tip of closed wing .07 inch. On June 3rd, 18G8, [ first observed a few of the winged specimens on the leaves of the White Pine, and in order to investigate their origin, I boxed a number of the lice (Coccus pinicor tic is, Fitch) taken from the body and limbs of the pine trees. The next day, I obtained from the feeding box three winged specimens of Chermes pinfolise, Fitch, and upon making an examination of the trees, I found them very plentifully on the leaves, counting from three to six on a single leaf. On June 8th, I had great difficulty in finding one perfect specimen of the winged imago, the cold rain which had fallen since the 4th, seem to have almost entirely destroyed them, many dead ones, with their wings shrivelled, were found adhering to the leaves. From the 8th to the 25th of June no winged specimens could be found. I had originally prepared much more extended comments on this subject, and notes from my observations, but for the present the above will suffice to clear up the confusion thrown upon this highly interest¬ ing subject by the writings of Fitch and Walsh, the latter even teach¬ ing that the Coccus pinicorticis and Aspidiotus pinifolise, are synony- AMERICAN IIOMOTTERA. 385 mous, ( Pract . Ent. i, 90), which teaching is manifestly erroneous It requires but a moments observation to see that the Aspicliotus pinifolise is of the same family as the “apple bark louse,” and that it therefore belongs to Lep idosaph idee ( Trans. Am. Ent. Soc. i, p. 373, Jan. 1868). The “ White Pine louse” is extensively preyed upon by natural ene¬ mies, among which I have observed the following : 1st. — An interesting heteropterous insect that, in the larval state, much resembles a brown ant, and runs about on the tree with a like activity. This insect Mr. Uhler has kindly determined to be Cama- ronotus fraternus , Uhler. 2nd. — The larva of an apparently undescribed Clirypsopa which covers its back with the wooly down of the plant louse. 3rd. — The black lady-beetle — Chilocorus bimdnerus, Muls, abun¬ dant. 4th.—Scymnns terminating, Say; and a somewhat similar but smaller lady-beetle Pentilla misella , Zimm. MS. as determined by Dr. LeConte. This beautiful little insect is one of the smallest of the lady-beetles, is entirely black, the antennae are hairy, the club quite close, much more so than that of Scymnux terminating , the first joint thick, 2 — 8 slender, 6 — 8 very short, 9 and 10 campanulate, 11 truncate, conical; legs hairy. 5th. — The larva of a species of Scymnm , longer than that of S. ter- inatus, and from which l bred a beautiful Chalcis fly. * 6 th. — Many larvae of unknown species of Syrphidse. ^Eutelus! scymn.Ee, n. sp. — 'J, Thorax large, abdomen short, body brown, covered with short hairs; head moderate, a broad, light yellowish band placed vertically on median line of the face; ocelli none; eyes large, elongate, reticu¬ lated with whitish depressed lines ; legs lighter brown, naked, tarsi whitish, spurs of middle tibire more than half the length of the tarsi ; middle legs long and slender ; hind femora stout and curved inwardly, antennm long, slightly downy, dark brown, except the terminal half of flagellum, which is white, tip acuminate; wings grey-translucent, a dark spot at base, and a broad blackish band across the middle, fading into lighter posteriorly, tips slightly fuliginous.

A SUMMERS STUDY OF HICKORY GALLS, •with descriptions of snpposod new insects bred therefrom. BY IIENRY SHIMER, M. D.

Carroll, Ills., I was induced to make a careful study of them with a view of settling in my mind, as far as possible, their true relationship. Deem- ' ing the results attained thereby sufficiently important to science, I here¬ with present them to the entomological public. Synoptical Table of Galls. 1.

Hall No. 1. * — This is a large, subhemispherical gall, situate in the parenchyma of the leaf, generally projecting above the plane of the latter. Structure somewhat thick, tough and dense, the average thick¬ ness of the walls being about .05 inch. Color pale whitish-green, much paler than the leaf, the upper surface frequently tinged with red and often quite purple-red. Size : diameter in the plane of the leaf, £ to 2 inch ; vertical diameter one-half. * The description of this and the following galls were made from specimens in their most perfect state of development, and before the maturity of the insect that produced them. AMERICAN IIOMOTTERA. 387 These galls open beneath with a slit, the length of which is about one-third of the diameter of the gall ; its direction is usually in, or somewhat oblique to, that of the veins of the leaf, and when oblique, more nearly parallel with the longitudinal axis of the leaf. The lips of these slits are pinched so tightly together as to project out and their margins are either smooth or slightly hairy. Sometimes a leaf contains but a single gall, others two or more. The galls may be scattered irregularly on the leaf, or placed in one or two rows along and near the mid-rib, and one or two dozen may be found in a single row, placed so closely together as. to be contiguous. Upon opening one of these galls, I found the mother insect and her eggs, the latter in great abundance, one hundred or more, studded all over the concave surface; but very few eggs had then (June 7th) hatched. But on opening one of the largest galls, which seemed to be in a much more advanced state, I found the mother insect in the midst of a very numerous brood of newly hatched larvae, and also many eggs still unhatched; the new-born larvae were pale greenish-white, while those more advauced were of a deeper color and of all shades approach- iug to orange; many were already in the pupa state, having short wing- cases. The mother insect moved in a stately manner among her nu¬ merous offspring, apparently proud of her queenly position. On June 18th, the galls were in prime condition for examining the inhabitants; many were opening at the slit beneath and the winged imagos escaping in great numbers. The following is a description of the species. * Dactylosphsera hemisphericum, n. sp? ? Phylloxera caryce-globuli, Walsh, Proc. Ent. Soc. i, 309. Winged Liago. — Light orange yellow, head, autennse, legs, and a band around middle of thorax blackish; abdomen pointed; wings delicate, hyaline; an- tenme (viewed with a sample lens, apparently 3-jointed. Length of body .04; to tip of wings .00 inch. Microscopic view. — Antennre 5-jointed, the first two, as usual, short and thick ; third longer; fourth slender, shorter than third; fifth clavate, longer than third and fourth and about as thick as the third ; these joints do not appear so evident in all specimens, as sometimes only four are discernable, and some¬ times the microscope separates the antenna on one side into four joints, and that on the other into five. Promuscus slightly hairy, 3-jointed, the middle * The description of this and the following species were taken from living specimens. In making microscopical examinations, especially of the feet, I find it best to place the living insect upon the glass slide, for, when it is anes- thised it rests with the claws contracted under the foot and they cannot, there¬ fore, be seen; whereas, when the insect is in motion, the claws and digituli are clearly observable. 388 HENRY SHIMER, M. D. joint shortest anil thickest, and the third longest. Legs slightly hairy; femora very thick above, slender in the middle, being not half the upper diameter, then swelling out and clavate toward the lower end ; feet with one joint, two claws and two digituli, which have clavate ends. Mother Ixsect. — Pale greenish-yellow, orange-yellow about the head ; anten- nre, proboscis and legs black; abdomen pointed, very versatile. Microscopic view. — A few very short, fine, black hairs scattered over the body ; three spiracles are seen along each side; surrounding the femur, there is an inverted conical or bell-shaped cup, bordered with black, within which the limb has room to work freely, and outwardly a frsenum or skin attaches the side of this cup to the body, its lower margin black and about as large as the diameter of the cup. Proboscis projecting downwards between the fore legs. Eyes black- Tarsi with one joint, two claws, two long globe-ended digituli, and several hair¬ like spines. Antennre 3-jointed, first two joints short and thick, subglobular, the last long and clavate. Pupa. — Pale orange, wing-pads lighter; eyes brown ; ocelli red; feet plainly showing two digituli. Of the winged imago thousands were observed, each gall containing from thirty to forty specimens. On June 18th, I found no eggs, only a few larvae and many pupae. I am rather suspicious that this maybe the Phylloxera caryse-glohuU of Walsh ; but he says ( ibid .) that the gall of his species is “ spherical,” and also that the size of the insect is “ .07 to .08 inch in length and that the abdomen is blackish. But unless described from living speci¬ mens, the color is of no value, as they all turn black after death. Gall No. 2. — On the same leaves with the galls described above (No. 1) I found (June 7th) many presenting the following characters : Flattish, opening both above and below, in nipple-like projections, both surrounded by a downy substance, the upper opening being smaller and closer. On opening the gall by a vertical cut, I observed a partly broken septum in the plane of the leaf, the border of the partition remaining, but the centre gone. A flat, dense, rim-like border extended around this septum into the parenchyma of the leaf, beyond the gall, so that the margins of the cut gall presented quite an acute angle. The greater part of the gall was above the leaf and its cavity was somewhat like two cones, with their bases together at the septum, the upper being much the larger. I opeued one gall in which the inhabitants had perished when it was about one-fourth grown ; in this the partition was com¬ plete. Diameter 1 inch; inside diameter .08 inch; distance between the vertical orifices .15 inch. Phylloxera caryse-folise, Fitch (2d. W. Y. Pep. § 1G6), has a some¬ what similar gall, but that opens only above, while the one under con- AMERICAN IIOMOPTERA. 389 sideration opens both above and below, the principal opening being beneath. Dactylosphaera caryae-septum, n. sp. Winged Imago.— Light orange-yellow, with a black band around the thorax; the general resemblance being quite similar to the species from gall No. 1. Length of body .04; to tip of wings .00 inch. Mother Insect — Pale greenish, slightly yellowish anteriorly; legs, antennas and some spots on the back, blackish ; apex of abdomen obtuse, terminated by a small central point, somewhat emarginate ; otherwise like the mother insect from gall No. 1. Length .25 inch ; breadth .15 inch. Gall No. 3. — On June 7th, I observed, placed in the common petiole of the leaf, large, elongate, subelipsoidal, nut-like galls, of a deep leaf-green color, mottled with paler green, and somewhat nodulated; some were irregular, being on the side of the stem; but most of them are quite regular in form, and completely surrounding the stem; in these- latter the leaves are very much dwarfed. The opening is on the middle of the side, slightly elongate, but at this date so close as to be scarcely apparent. These galls contain capacious cavities, in which were found vast colonies of larvae, and an abundance of eggs. Trans¬ verse diameter | inch; conjugate diameter | inch. By June 20th, these galls had considerably changed in appearance, being contorted into different shapes; they had began to crack open, having transverse tissues on their outer surface. The first one opened contained many hundred winged images, all dead, and in the midst of them was a large syrphidian larva. I found only one gall that con¬ tained perfect living imagos, the inhabitants of all the other galls that were examined, having been destroyed by various enemies. Dactylosphsra subellipticum, n. sp. Winged imago.— Large and robust, blackish, with abdomen light yellow; antennae end legs blackish ; wings hyaline. Length of body .03 — .07 ; to tip of wings .OS — .09 inch. Mother insect. — Rugose, greenish-yellow ; antennae and legs black ; otherwise like that from gall No. 1. Length .09; breadth .04 ; thickness .03 inch. The winged imago of this species is the largest yet observed, and the eggs are more nearly globular than those found in other species of galls. Gall No. 4. — These galls were found to be exceedingly numerous on some trees. On June 20th, they were smooth, slightly rounded above, pale yellowish-green; beneath somewhat whiter, and having in the centre a nipple-like projection; opening round, surrounded with a burr¬ like fringe composed of many filimeuts, the cavity like an inverted cone, the wall above being quite thin and translucent, so that the inmates 390 IIENRY SIIIMER, M. D. may be seen moving about. This apparently very flat gall was placed as much below as above the plane of the leaf. Diameter .15 — .25 inch ; vertical thickness .125 inch. Dactylosphaera depressum, n. sp. Winged imago. — Yellow; head, antennse, legs and a band around the thorax, black; antennie 3-jointed; otherwise as in specimens from gall No. 1. Length of body .04; to tip of wings .06 inch. Gall No. 5. — A subhemispherical gall, projecting beneath into a conoidal point, with a round opening. On June 21st, these contained a great number of pupte, and a few winged images. The walls are very thick and the opening below quite close, so that little or no light gains access to the cavity. This gall matures its inhabitants about one week or ten days later than does gall No. 1, which were at this time almost all gone, while these are only just commencing to develope the perfect insect. Dactylosphaera conicum, n. sp. Winged imago. — Yellowish-white; head yellow, with a blackishline between the eyes; a dusky band around the thorax: antenme and legs pale; wings whitish-hyaline, lying flat on the back in repose; antennse 3-jointed, the last joint long, subclavate, terminated by two minute points; tarsi with one joint, two claws and two digituli, the latter having fine subglobular ends; abdomen slender, pointed. Length .05 — .06 inch. Galls on the Bitter-nut Hickory (O'. amara). Gall No. C. — Subglobular galls, varying in size from a quarter of an inch to one inch in diameter, the average being about half an inch, situate on leaf or its stems or mid-ribs; color greenish-white, sometimes with a blush of red on one side. The opening is beneath, in the shape of a small, elongate slit, which at length cracks open, like a chestnut burr, in three or four long slits running up the sides; after this the gall soon turns black and dries away. The cavity within is capacious, the walls being about i in thickness. On June 17th I observed thousands of these galls and took home a large botanical box full for study. They were so numerous as to in¬ jure the growth of the trees. Those galls that had not yet began to open, and within which no parasites had gained access, were so thickly studded with young lice, that their abdomens pointed directly inward towards the centre, resembling the crystals in a geode, being wedged in as densely as mosaic work, while the whole central cavity was crowded with winged imagos; the former held on with great tenacity, while the latter were easily shaken out. In one gall I counted as many as one thousand inhabitants. At this time (June 17th) many of the galls had cracked open and the winged imagos were escaping in immense num- AMERICAN IIOMOPTERA. 391 bers. rVo eggs were found. 5' The larvae were pale greenish-yellow. On June 25th the galls were all dry, black and deserted. Dactylosphsera caryse-magnum, n. sp ? f Pemphigus caryce-caulis, Fitch, 1st N. Y. Rep. p. 155. Winged imago. — Head and thorax brownish or black ; abdomen pale lemon- yellow; prothorax, sometimes the whole thorax, yellow; antennte and legs dark gray; wings hyaline, iridescent, lying flat on the back in repose; under a high magnifying power the antennae appear slightly rugose, hairless, 4-jointed, the last joint terminated by twominute spines; and the legs appear corrugated, showing minute rings, and are slightly hairy; tarsi with one joint and two claws; stigma dark and conspicuous. Length of body .06; to tip of wings .08 inch. Gall No. 7. — Small round galls, generally very numerous in the leaves, and in some cases almost entirely covering them, a single leaf sometimes containing upwards of 250 galls ; the average size larger than those of No. 8, although often quite as small, the larger ones mea¬ suring three-sixteenths of an inch in diameter. They were (June 25th) quite hard and smooth, and present, especially above, a bright shining appearance; They were quite thick and plump, the vertical diameter compared with the horizontal diameter being as 2 to 3, and were much more plump and elevated above the leaf than those of No. 8. The por¬ tions of the leaf between the galls had in some cases turned crimson. I found from three to twenty-five inhabitants in a gall; the round opening beneath was so close as to be pretty safe against enemies, as I found none in the galls opened thus far. Larvae and pupae whitish, with red eyes; mother insect cinnamon color and smaller than the pupa. On July 5th, I found winged images in all the galls, large and small, that were opened, the smallest galls not much exceeding .05 inch in diameter; when opened, the young insects eagerly ran out, and all presented the same pale, translucent appearance, with minute dark spots on the anterior part of the body, which is in contrast with the inhabi¬ tants of gall No. 8. The winged imago was first observed on June 30th. Dactylosphsera minimum, n. sp. Winged imago. — Body, antennae and legs, pale yellowish-white; the head and a band round the thorax, dusky; wings on the back in repose, translucent, neu- ration obsolete, the stigma scarcely perceptible. Length of body .025 — .03; to end of wings .045 — .05 inch. These insects are much smaller, paler in color and less disposed to fly than any of the other species noticed in this paper.

I verified this same circumstance in several other small galls of this species, and it therefore appears probable that the winged imago was the mother- insect, developed into the winged state, although we have heretofore considered them as males. On the surface of the leaves bearing these galls, were observed nu¬ merous, small unknown acariaus, in all stages of development, from the egg to the perfect insect. They somewhat resemble a species found abundantly on the White Maple. Gall No. 8. — Resembles gall No. 7, but generally smaller, less firm, more leathery and pliable, less rounded above, and some yellow in color. They are very numerous, having counted as many as eight hundred on a single leaf; where they are thus crowded together, they are very small, say from a 25 — .10 inch, in diameter. On June 9th the eggs were hatching and the young could be seen running about on the leaves as well as in the galls. The mother insect o o was then a pale yellowish, subglobular mass, length .02 inch. On July 23rd, I found the galls still containing both eggs and larvae, the older galls becoming uninhabited, while up on the top limbs and young shoots, the new galls were becoming so numerous as to interfere with the growth of the leaves, and it appeared impossible for the galls to develop. Although I have never succeeded in finding a winged imago, after having examined hundreds of galls, I presume it to be identical with the species mentioned by Mr. Walsh, ( Proc . Ent.. Soc. Phil, vi, 283), as caryse-semen. Should it not prove to be a variety of D. globosum, the name will be as follows : Dactylosphoera caryas-semen. car yoz- semen, Walsh, MS. Proc. Ent. Soc. Phil, vi, p. 283. For a description of the gall, egg, larva, and mother insect, see my paper in Proc. Acad. Nat. Sci. Jan. 18(37, where I included it under D. (jlobosum ; because, although the galls were of different size, I could not detect any difference in the eggs, larva; and mother insect, and for other reasons there assigned. It must be admitted, however, that the similarity of the inhabitants, same color of eggs, and lateness of develop¬ ment of both galls are characters of great weight; and Mr. Walsh, in his First Report on the Noxious Insects of Illinois, says that the ana¬ tomical differences between the galls of his caryse-globali and cart/x- AMERICAN II OM OTTER A. 393 semen are quite well marked, the former opening with a slit and the latter with a round nipple-like projection, &c. &c. Gael No. 9. — On the same leaves containing the small galls, Nos. 7 aud 8, I observed a number of larger ones with a dimpled depression above (which may be caused by the collapse of the thin paper-like centre), an opening beneath by a rounded, downy orifice, and having a diameter of .03 — .33 inch, and a vertical depth of .12 — .16 inch; all contained the female and her eggs, and some larvae. Dactylosphsera foreatum, n. sp. Winged imago. — Abdomen and prothorax pale orange, with a dark band or ring around the mesothorax ; wings carried flat on the back in repose, hyaline, veins small, stigma very faint, smoky; antenna 3-jointed, the last joint long, 6ubcylindrical and on a very long pedicle; abdomen quite pointed. Length to tip of wings .06; of antennee .005 inch. Motiier insect. — Pale yellow, palest posteriorly. Length .04; width .02 inch. On June 20th the winged imagos were very plenty, but no eggs could be found. Gall No. 10. — This is the gall of my D. globosum , described $t length in Proc. Acad. Nat. So'. Phil ., Jan. 1867, and, with No. 8, are the only known Hickory galls that have the character of being soft and leathery in structure. The perfect insect was found between Sept. 20th, and Oct. 20th 1866, since which time I have not seen it. I then described it as being found on what I supposed to be Carya glabra , but which now proves to be C. amara. See below. This is so manifestly distinct from caryse-globuli. , Walsh, that a com¬ parison is uncalled for; the latter is said to mature in June, while globosum matures in October; and the opening of the galls are quite different in shape, that of globosum being rounded and on a nipple-like projection, while that of caryse-globuli is an elongated slit. I am not at all certain that Gall No. 8, is specifically distinct from this. I found all the above mentioned galls, excepting Nos. 7, 8 and 9, drv and depopulated on J uly 6th ; and on J uly 21st, 22nd and 23rd, I made a careful examination of all the species of galls here enumerated while yet on the trees, and found them all dry and depopulated except No. 8 and a few of No. 9, which although entirely free from their legitimate inhabitants, were yet green and quite firm, and in each of them T found a pupa of some unknown parasite. This is quite an interesting circum¬ stance and shows how admirably nature provides for the life of all things, in the instance of this gall maintaining its integrity so much beyond the normal time, for the preservation of an intruder ! (51) TRANS. AVER. ENT. SOC. DECEMBER, 1869. HENRY SHIMER, M. D. 394 I have made the foregoing descriptions of the several species of Dar- ft/losphxra , excepting No. 1, quite brief, because of the general simi¬ larity of the perfect insect ; yet, the difference in the anatomical struc¬ ture of the galls, the season of their development, the different sizes and shades of color of their inhabitants when in the living state — for they all become black and undistinguishable when dry — constitute a sufficient reason for assigning them to different species. That there really is more than one species there is probably no doubt, certainly not with those naturalists who even go so far as to name galls without knowing their legitimate inhabitants. During the period of my studies of the Hickory galls, I was the con¬ stant observer of the various parasites connected with both the gall itself and the inhabitants thereof The following brief observations 1 will make : Parasites of the galls. — 1st. In many galls I observed an unknown species of Thrips , quite abundant, with red bodies, and antennae, legs, and tip of tail black. Length .01 inch. — 2nd. Conotrachefns posticatus, Schbnh., the larva of which lives in the galls, chiefly of No G, often consuming its entire substance; it is a yellowish-white, slightly hairy, footless worm, with head and collar light brown. They had finished feeding and entered the ground about last of June, and the imagos ap¬ peared on July 21st. This is probably the same species with Dr. Fitch’s C. elegans (1st N. Y. Report, p. 156.) — 3rd. The larva of Anthonomus crj/thropus, Say, was also found within some of the galls; it is a white, rugose, footless, quick-motioned worm about .20 inch iu length; it transforms within the gall ; the pupa is white, back much curved, tail sharply pointed, and has a number of short reddish bristles about the head and tail; it wriggles about very rapidly when disturbed. 4th. Larvae of the following new species of Graphofitha were found in August and September living in the nut of Cart/a amara (Bitternut Hickory) ; they destroy the interior of the nut, causing it to fall to the ground; the imago appeared iu the latter part of November, it there¬ fore hibernates in this state and continues to live in the spring until sometime in June, when the nut is sufficiently developed to receive the egg- Grapholitha caryae, n. sp. Palpi whitish except the minute third joint which is blackish. Head ashy grey, scales long, especially on the occiput. Thorax and abdomen blackish ; patagia with a bluish tinge and a few pale scales posteriorly. Anterior wings •lark brown, with numerous ferruginous scales, most prominent on and beyond AMERICAN IIOMOITERA. 395 the middle. Anterior margin with short whitish streaks from near the base to the apex where they are most distinct. A diffuse rounded dark brown patch in the outer third of the wing is filled in with blackish scales. Fringes dark, blackish. Posterior wings above grey anteriorly, posteriorly bluish-black : beneath blackish with a greyish center. Under surface of thorax and legs clothed with whitish scales. Expanse .52 inch; length of body .23 inch. Two male specimens bred. Parasites of die gall-lice. — The larva; of certain Syrphidae were fre¬ quently found especially in the larger galls; none were bred to matu¬ rity. The larvae of two species of Leucogis were also found feeding upon the young lice; one species, which was white or yellowish-white, sometimes as many as fifty were fouud in one gall; the other species was red and quite similar to the new species of Leucopis I bred from the grape-leaf louse” ( Pract . Entom. ii, 17), and which has since been described by Dr. Loew, under the name of simplex. Two unknown species of Chalcis-flies were also bred. From the inmates of some of the galls I also bred a species of Ceci- domyia, having the following characters : — Bcdy fuscous, pubescent.; anterior part of abdomen imperfectly banded with black; antennae reddish, covered with grey hairs ; wings light fawn color, spotted with dusky, the spots arranged in little arcs, forming three broken bands ; femora reddish; tibiae banded with black and white; halteres reddish, on a white pedicel. Length of body one-sixteenth of an inch. Should this species prove to be new, it may be called C. cossse. In support of the assertion made on page 393, concerning Carj/a glabra and amara, the following observations are here added : In October, 1868, after examining with great care, the fruit of the hickories in the region of Mt. Carroll, I became convinced that besides Cari/a alba, we only have in this place C. amara. I have had an opportunity of examining these hickories in this and some adjoining counties, and find no nut that agrees with glabra. I had been long aware, both from reports of mechanics and from per¬ sonal observation, that the young hickory sapling here is not so tough for hoops and withes as those in Pennsylvania, where the true pignut hickory is abun¬ dant; but the nut itself is the best guide to correct determination. The kernel of the nut of C. amara is always quite bitter, and much corruga¬ ted, shell so thin that it is easily broken with the teeth, and I have broken the whole nut with my hand ; any of them can easily be cut in halves with a knife, and then readily crushed in pieces with the fingers. The stigmatic extremity usually projects into a long sharp spine; husk thin and leathery-like, soft, split from the apex only about half way to the base; 3 to 5, usually only 4, promi¬ nent hinged sutures at the upper end; this last character is not persistent, but gradually disappears in a series of specimens, so as to be entirely absent in the nuts of some trees. The form of the nut varies between cordate and oblong- alipsoidal; leaflets 7 — 9 — 11 ; bark at first smooth, but as the tree grows older it 396 IIENRY SIIIMER, M. P. becomes rough and corrugated. The trees seldom attain more than a foot in diameter. Winter bud small, slender, not smooth, yellowish. Abundapt in the prairie groves and copses on the low bank of water courses. There appears to be two varieties of the C. atnara. In the usually described variety, the leaf is immaculate, and to this the gall No. 6 is entirely confined. In the other, the leaf is sprinkled with small, grey, glandular dots beneath, which remain persistent during the summer, and to this the galls No. 7 and 8 are exclusively confined. The peculiar choice of these insects, would lead us to believe that the tree with the dotted leaf may be a new and distinct variety; but I have not yet made a sufficient examination of the fruit to decide this point. Nuts found on the trees bearing gall No. 7, do not materially differ however from those of the tree bearing gall No. 6. I have never yet found the fruit of a tree bearing gall No. 8, but judging from the leaf, bud and bush, I know it to be identical with the trees bearing gall No. 7. Neither did I find galls Nos. 7 and 8 on one and the same tree. The locality of gall No. 7 was a mile from that of gall No. 8. The trees are in all respects similar, both having the small dots under the leaf, and very probably the galls will be found together. This tree, with the thick sprinkling of small grey dust-like glands beneath the leaf, may be designated as Carya amara-glandula , by way of distinction, at least to answer the purposes of entomological research. I spent the 4th of November 1868, at Rock Island — a portion of the morning on the Island, and the afternoon among the bluffs to the eastward of the city — examining the hickory trees and their fruit. I found, C. alba, C. ainara, and a solitary tree of C. iomentosa, I did not see a single tree of C. glabra. To render my determination of C. atnara more certain, I carried with me to Columbia College, New York City, a number of the nuts for comparison with the specimens in the collections there; and through the kind assistance of Dr. Torrey, Professor of Botany at the college, and Mr. LeRoy of Peekskill, it be¬ comes entirely positive that the nuts gathered, both in the vicinity of Rock Island and of Mt. Carroll, are those of C. a mar a ; and that there are no fruit bearing trees, and therefore probably none of the C. glabra, in either of those localities. Mt. Carroll, Ills., April, 1863. NOTE. During the summer of 1863 I made the following observations on Hickory Galls in the vicinity of Mt. Carroll : June 18 th. — Gall No. 6 already had winged imagos and eggs, the lat¬ ter were not found last year. They were translucent-whitish, abund¬ ant, length .005 inch. The first gall observed contained two mother insects. June 20f/i. — Gall No. 9 was far more abundant than last year and AMERICAN IIOMOPTERA. 397 some of them twice as large, their width being from 3-16th to 6-16ths of an inch. Gall No. 8 were found to be very numerous on the same trees as last year. June 29 th. — I confirmed the observations I made on the various galls last year, and discovered two new species, described below under Nos. 11 and 12. Gall No. 6 were very numerous and much more abundant than last year, sometimes a dozen was found on a single leaf, destroying it and often much injuring the tender branches. The weather was en¬ tirely too wet for the health of the inhabitants, and they were also found to be greatly afflicted with parasites as well as disease, and com¬ paratively few reached the perfect state, compared with the millions of last year. Even the curculio larvae, so abundant in these galls, were found to be much preyed upon by a species of chalcis-fly, and at this date I found plenty of eggs in some of the latest developed galls. In the early part of the gall-season I observed many specimens of the Tlirips , that infest them, ou the leaves and some in the act of forcing an entrance into the galls. I also observed specimens of Anthonomus erythropus, Say, on the leaves seeking the galls, and even found one with its abdomen inserted into the opening of a gall, evidently in the act of ovipositing. Some pale amber colored eggs, half the size of those of the plant-lice (evidently deposited by some intruder) were also ob¬ served. Gall No. 11. — Very thick, depressed, slightly elevated above the leaf, conical below ; contained many larvae and yellow pupa, but at this date (June 18th) too late to find the eggs. This gall is almost like No. 4 with the walls much thicker. Dactylosphaera coniferum, n. sp. Body brownish; abdomen, and in some specimens the mesothorax, pale yel¬ low; antennae three-jointed, the last joint very long and on a slender pedicel; tarsi very long, with the twodigituli almost as long; claws two, as usual; wings ample, carried flat in repose, neuration nearly undefinable, stigma slightly clouded. Length of body .025 ; to tip of wings .05 — .04 inch. Many specimens observed. Gall No. 12. — Yellowish, pubescent, covered with spines, quite ir¬ regular; opening beneath elongate, sinuate. This gall, from its being spinose and irregular, is quite in contrast with all the others of the series. Dactylosphaera spinosum, n. sp. Winged imago. — Head and thorax black or brownish; abdomen yellow; an¬ tennae four-jointed, the third joint much shorter than fourth, tipped with a hairy spine; tarsi long; wings carried flat in repose. Length of body .03; to tip of wing .06 inch. 398 HENRY SIIIMER, M. D. Pupa. — Color, light orange ; back covered with long spines — quite in contrast with the pupa3 of the other species which are all smooth. Larva. — Pale yellowish, abdomen covered with spines. Egg. — Elongate-ovate, twice as long as wide, pale translucent greenish. Length .008 inch. This is an interesting example among this series of galls, wherein the gall and young differ much more evidently than does the imago. The spiny gall and prominent spiny tubercles covering the body of the young, widely separates it from the preceding species, and yet the imago has much the appearance of that inhabiting the other galls. This is a strong, if not conclusive, argument in favor of the validity of the several species proposed. Mt. Carroll , Ills., October, 1869. -o- ERRATA.
