TRANSACTIONS OF THE AMERICAN ENTOMOLOGICAL SOCIETY voIvUnie: XXXIX. Notes on CHLAMYDAE with descriptions of a few new forms. BY FRED. C. BOWDITCH. The new arrangement of my material in this group shows a number of interesting new forms. For the benefit of any- one who may work on this family I will detail a method of mounting which is effective ; easy inspection of the antennae and prosternum is necessary, so that I am prone to mount all, except very small species, on fine japanned steel pins. Place the specimen to be mounted in a weak solution of ammonia and water (Wenzel's method), if it is glued on a card, as is often the case, by the time it bobs to the surface it is usually ready to handle. Remove with small forceps onto blotting paper, brush off any stray dirt, and when dry turn face down, and with pinning forceps run a pin through into the blotter, still holding the forceps, raise the pin and insect, and place on the edge of a small block of paper and run the pin through to the desired height. Usually I hardly touch the specimen with my fingers, only sometimes steady- ing it. If I have several of one species one may have the antennae exposed, in which case I brush it out to show or mount one on a piece of card. If only one specimen is at hand it requires patience to get the antenna out of its groove ; the specimen should be left longer in the softening bath and the visible moisture be allowed to dry ofT on the paper ; my usual way is then to take the specimen between the thumb and forefinger of the left hand upside down and head out- TRANS. AM. ENT. SOC. , XXXIX. (1) 2 COLEOPTERA CHLAMYDAE. wards and so held that the anterior edge of the thorax is supported by the finger, then with a fine needle pry the head out of the thoracic -cavity ; if the specimen is rightly held the necessary pressure to accomplish this comes against the forefinger and does not loosen the thorax, when the head starts, the antennae come out and are easily spread, the specimen with displayed antennae may be conveniently in- dicated in the collection by a small square of colored paper. The characteristic hump and median sulcus of the thorax presents great variety of shapes and sizes ; a common feature is to have the thorax cut away behind, leaving the upper edge more or less carinate ; this cutting away is spoken of as being declivous behind, and in very many forms the part next the sulcus and some of the hump anteriorly is more or less colored or darkened so that the thorax appears spotted. The base of the declivity runs around the hump more or less plainly to the front and forms the basal sulcus. The sculpture of the elytra (aside from the punctures) con- sists primarily of four lines or costae, a sutural, median, humeral and sublateral. From being entire, they vary to wholly absent, but in a great majority of cases they are more or less present, though broken or divided or varied by humps, tubercles or ridges. The most constant and im- portant appear to be the median and humeral, especially the latter. The shape of the prosternum presents great differ- ences and should be carefully compared. In the Entomologist for 1904, p. 198, Mr. Jacoby de- scribes Chlamys seminigra. Mr. C. J. Gahan kindly writes me that the type (in British Museum) is a female, Mr. Jacoby speaks of other specimens in the Donckier col- lection. These are before me, three cf's, seven 9 's, the epistome of the c? is profoundly excavate while the head is hardly enlarged beyond that of Chlamys, the species prob- ably will have to go into a new genus, but for the present it may be put with Pseudochlamys. Among the specimens in the second Jacoby collection labelled nodosa Klug. from British Guiana, is a very fine example of C. chevrolatii Fauv. It is larger than the nodosa, FRED. C. BOWDITCH. J more shining, with sulcus of the thorax much dilated ante- riorly. In Proc. Zool. Soc, 1901, Mr. Jacoby describes C. hisu- laris from Haiti. He had previously used this name for a Central American form, Biolog., p. 78. So for the former I would suggest the name haitiensis. C. boliviana Jac. has at the rear of the thorax on the crest of the declivity four obsolete tubercles, in a semicircle, analagous to deyrollei Jac. or kermes Lac. The rear of the thorax is obsoletely toothed, approaching amazonica Jac. and humeralis Bow. A form which at present I regard as a variety of boliviayia, occurs in which the elytra have a nar- row, transverse yellow fascia from shoulder to shoulder, the front edge of the fascia just taking in the scutel. This variety is from Cochahamba, Bolivia. The types of all the new species described in this paper are in my collection. Pseiidochlamys ? rufescens nov. sp. Rufous, with here and there darker clouds. Head very large, flat, with great mandibles, thorax very thickly and finely punctured, with a rounded hump, median sul- cus very faint but discernible behind, where it is bordered by two dark clouds after the manner of many Chlamys, suture smooth, prosternum wide, very abruptly narrowed, at about the anterior third, remaining two-thirds a little less narrow and parallel ; length 4f mm. 7>/^.— One c? : St. Catherine, Brazil. My only example of P. megalostomoides Lac. is a 9 , so I have no opportunity to compare the characteristics of the cf, but the epistome of rufescens seems hardly sufficiently ex- cavated to bring it into this genus, the excavation is smooth and slightly concave, not "cavernous," the margins slightly thickened and the angles prolonged, the scape of the an- tennae is much thickened at the end and somewhat angularly prolonged inward. The hump of the thorax is very large at its base and occupies nearly the whole width of the thorax. The elytra show faint elevated lines in the usual places, with faint connections and tubercles here and there, the most prominent of the former is ante-median, a little to the side. There is a very moderate tubercle at the middle of the base, TRANS. AM. KNT. SOC, XXXIX. 4 COLEOPTERA CHLAMYDAE. and the apical region shows a good many broken and one fairly marked sutural ridge. The elytra are somewhat com- pressed laterally behind the shoulders, pygidium coarsely rugosely punctate with a faint median line, pectus and thighs with a dark spot. Diaspis apicicollis nov. sp. Bronzed, thorax greenish ; elytra coppery brassy, becoming dark behind ; labrum and antennae dark fulvous : thorax elevated behind into a high peak which is bent back- ward at its apex ; sulcus well marked behind and at apex of hump, becoming obsolete in front ; metascutellum very plain ; elytra narrow behind with a very strong oblique ridge from the humerus almost to the suture, which is dentate ; prosternum broad, very moderately compressed and obtuse behind ; length 3.5 mm. Type. — One d^ ; Toledo District, Br. Honduras (Peck). Head finely punctate, with a fine line on the vertex, thorax rather smooth and dull, with scattered fine punctures which gradually become thick and large, going up the sides of the hump, which is well limited at the sides and behind by a smooth basal sulcus, which is continued towards the front by a shallow depression vaguely colored greenish. The hump has the appearance of being pulled back, with the apex bent back so that it is on a line with the rear edge of the thorax. Elytra are sparsely punctate, more closely behind, the oblique ridge running very strongly to about the middle of the suture ; it is joined, or nearly so, by two lines from the base, one sutural, the other basal median. Between these two short lines is formed a deep pit which shows brassy bronze, including the scutellar region ; the oblique ridge forms the forward edge of an oblique constriction ; the usual elevated lines show faintly at the rear as two or three costiform tubercles and the punctures become obso- letely reticulated ; pygdium punctate, uneven, with a faint median line. As a matter of convenience I prefer to retain the old name Diaspis aside from Mr. Schaefifer's paper in the Brooklyn Bulletin. The noticeable features are the thoracic hump, the oblique ridge and the coloration. FRED. C. BOWDITCH. O Chlaniys riig"icollis nov. sp. Quadrate, above bluish-green, cyaneous shining ; below and legs purple, insides of femora more or less cupreous, pygidium cupreous, antennae, except the first joint, the mouth parts and tarsi, flavous ; thorax coarsely punctate, rugose on the hump, which is large and rounded, deeply divided by a wide sulcus which nearly attains the anterior margin, a well marked lateral tubercle and also one on the side of the hump near the tip ; pygidium moderately closely punctate and with a fine median carina ; pros- ternum very abruptly narrowed at about the anterior quarter to almost a knife edge ; length 5-5 j mm. Type. — &^ ; Jatahy Goyaz, Brazil, two cf's, one 9, three examples. Head of cf with front and vertex channelled, more or less cupreous, particularly the epistome, 9 not as bright and the lower part of the channel not as obvious, surface punctate, antennae with the scape more or less cyaneous, the second joint rounded, the third and following transverse and dilated, punctuation of the thorax coarse and thick with a tendency to become strigose, especially on the hump, at the sides, and behind ; the hump well elevated, reticulated punctate stri- gose, the ridges limiting the sulcus, branch obsoletely at the vertex and flow down over the subsidiary side tubercle, the sulcus itself is closely rugosely punctate ; the elytra are hardly compressed behind the shoulders, rather coarsely reticulate punctate in the intervals, especially at the sides and behind and with very strongly raised costae as follows : a sutural which curves outward, and then inward nearly to the suture at the middle where it curves outward again and joins the median (somewhat like surinamensis Jac), the median runs parallel to the sutural, then continues to apex, where it ends in a costiform tubercle. There are about two short transverse connections to the sutural and humeral near the middle, the humeral and subhumeralboth form costiform tubercles near the apex, the subhumeral and median have a inarked tendency to join in a loop at the apex. There is also a small tubercle at the basal end of the sutural costa — mesosternum hair. Belongs to Lacordaire's Group 7. TRANS. AM. ENT. SOC. , XXXIX. 6 COLEOPTERA CHLAMYDAE. Clilamys truncatus nov. sp. Elongate, opaque, head dark, thorax coppery bronze, elytra opaque brownish-black tinged with purple, end of the body squarely truncate, the truncation of the elytra bronzed, abdomen brown opaque, body beneath of the latter color ; antennae, except the end, labrum and tarsi, fulvous ; presternum with sides parallel at its front, then gradually narrowed to middle, the rear half a parallel edge , length 3.5 mm. Type. — 9 ; Cochabamba, Bolivia, two 9 specimens. Head thickly and rugosely punctate, antennae with second joint obconic, third stout and trigonate, remainder transverse, the last four or five joints dark, thorax with rather coarse punctures, not thick, hump large, declivous and well defined at the base, rather deeply divided by the median sulcus, which has a deep pit at the apex of the hump, and then is con- tinued broadly to nearly the anterior margin. Each side of the middle is divided by two irregular transverse ridges which pass down to the sides. There are two lateral tuber- cles, and the rear edge is prolonged and sharply notched behind. The elytra have the usual sutural and median lines, the others being broken. The entire surface is reticulate, becoming coarser at the apex. The edge of the truncation is marked on each side by two sharp, prominent tubercles, one sutural and the other median; suture finely dentate, pygidium punctate, obsoletely tricarinate, body beneath coarsely reticulate. The peculiar coloration and truncate elytra will distinguish this form ; belongs in Lacordaire's Group 7. Chlamys carinipennis nov. sp. Elongate, shining brown, body below, black, hump of the thorax darkened, its anterior apex deeply bilobed and elevated into two sharp fan-shaped carinae ; elytra with the usual lines more or less abnormally elevated into sharp carinae, apex abruptly truncate, suture smooth or nearly so, pros- ternum strongly margined with sides at first parallel, then abruptly narrowed to a trifle beyond the middle, then gradually enlarged again to an obtuse end, thus presenting a definite constriction at the middle ; length 3j mm. Type. — One cf ; Cochabamba, Bolivia.

BOWDITCH. / mainder transverse, the ends darkened, thorax polished, finely, sparsely punctate, becoming coarse and thick on the apex of the hump, which is strongly raised and sharply declivous and deeply cleft by the median sulcus. The apex is thrown forward so as to project beyond the head, and compressed, forming on each side a smooth, thin, sharp divergent fan-shaped edge. The margin of the sulcus to the rear shows as strongly raised into a supplemental ridge, which gradually disappears on the sides. The rear edge shows two small tubercles in front of the scutel, lateral tubercle not very prominent. The elytral punctures are sparse and fine in front, coarser behind. The elytral lines are strongly raised, leaving deep pits in the intervals, the sutural, median and humeral unite in forming a rather thick elevation about the middle. These lines are continued to the truncation and end in two strong tubercles placed on either side of the middle of the edge of the truncation, the pygidium shows a broad smooth line, carinate behind, deeply longitudinally foveate, on either side at the bottom, the sides of the abdomen and body are somewhat brown next the elytra, remainder opaque black, legs brown, thighs darker.

The brassy color and shape will aid in identifying this, should be placed next unicolor Jac. (type in my collection). Clilainys spinicollis nov. sp. Quadrate, cyaneous bronzed, head (antennae ?), sides of the thorax and two spots in front, whole body beneath except parts of meso- and metasternum bright orange- fulvous ; thorax with a six spined hump (three on each side) and each elytra with about twelve strong spinous tubercles, suture dentate, pro- sternum very narrow in front and becoming carinate behind, almost tuberculiform in front when looked at from side ; length 4^ mm.

Head finely punctate, with a small mark at the vertex, an- tennae with 2d joint short, 3d a trifle longer, cylindrical, 4th and 5th transverse (rest missing), thorax finely and closely punctulate, hump divided by a deep wide median sulcus obsolete in front, and each side divided again trans- versely, the effect being three tubercles on each side, of which the two along the middle are much the stronger and form obtuse spines, the hump proper is green bronze, and this color is continued by the median sulcus and an arm on either side to the anterior margin, forming two triangular fulvous spots in front ; the punctuation of the elytral intervals is coarse and rather regular, finer behind, each elytra has the following tubercles : a strong basal sutural, a smaller imme- diately behind, a large basal median, a small double humeral, a strong transverse lateral median and about seven scattered equally between the middle and apex, the apical sutural being perhaps the most prominent, the two basal and the transverse are the most marked, pygidium thickly finely and somewhat strongly punctate with a smooth median line ; body beneath thickly, legs more finely and sparsely punctate. The color and spiny appearance easily separate this form, which I place near spinosa Koll. Clilamys g-oyazensis nov. sp.

The most noticeable tubercles of the hump are four placed anteriorly near the median sulcus, one above the other on the anterior declivity : the median sulcus behind these is edged with a uniform row of small smooth tubercles ; anteriorly at the side is a costiform tubercle (seen from behind); of the elytral tuberosities there are on each elytra two at the base, a sutural and median, then there are a series of five much smaller elevations occupying the median belt, four of which are arranged in a transverse line in the mid- dle ; the apical portion is occupied by seven or eight strong spinous tubercles, one being sutural post median and a group of three arranged triangularly at the apex, these last being the longest of all. The usual elytral lines are faintly trace- able between the tubercles, suture finely dentate, abdomen coarsely punctate, sides obsoletely bituberculate. I place this species near schottii Lac. The dentate tibiae easily separate it. Clilamys siiinielirastii nov sp. Chestnut brown with a red- dish tinge to the thorax, the punctuation slightly darker, especially on the elytra, antennae dark at tip, thorax with a strong conical rounded hump (somewhat like natteri \Lo\\.)\ sulcus entire though not deep ; elytra impressed with rather large brown punctures, the usual lines almost obliterated, the humeral showing best, and ending in a small costiform tubercle ; the other elevations are small, the scutellar region is depressed and darker in color ; suture dentate in almost its whole length ; carina of pygidium obsolete ; presternum obliquely narrowed TRANS.

Type. — Isthmus of Tehuantepec (Sumichrast): formerly in the collection of G. D. Smith, of Cambridge, Mass., and labelled with the above name by the late G. R. Crotch. Form is subquadrate, compressed behind the humerus, 2d joint of antenae rounded, 3d short and trigonate, the punctua- tion of the thorax is thick and fine, becoming coarse and ru- gose on the tip of the hump and edges of the sulcus, which widens at the anterior apex and is marked on either side by the usual ridges ; the common lateral tubercle is only indicated by a very faint swelling, the sides of the hump are marked by darker clouds, and abruptly declivous, the markings of the elytra are vague, though viewed from behind a little to one side, the humeral ridge shows up plainly, while there are plenty of small tubercles and fragments of lines, nothing marked to catch the eye, body beneath coarsely reticulate ; somewhat resembles in appearance a very small specimen of discipennis Jac. without the thoracic spots of that form ; owing to the form of the thorax I place this provisionally in the natteri group though the usual elytral tubercles are wanting. Among my material is a chestnut brown 9 example from Maroni, Guiana, which I place provisionally as a var. of schottii Lac. It seems, however, to have many points of dif- ference, a few more examples, especially 9 , are needed. Lacordaire speaks of an entirely reddish form of schottii, I have not seen any such, and all my examples are from Brazil or Amazons. Chlamys plagiata nov. sp. Subquadrate, luteus, some spots on head and front of thorax and a large diamond-shaped spot taking in the hump of the thorax and extending beyond the middle of the elytra, velvety black, a little diluted at the rear end of the thoracic sulcus ; pygidium with fine median carina and a deep lateral elongate fovae ; prosternum gradually narrowed to about posterior two-thirds, then parallel to apex ; length 3-3^ mm.

Seems nearest to dorsalis Lac. which I have not seen. Easily separated by the light color with diamond shape dark spot. Clilamys gounellei nov sp. Elongate ; reddish rufous above, flavous below, last six joints of antenaae black ; thorax with a large rounded hump, obsoletely sulcate ; elytra with the usual raised lines and everywhere coarsely reticulated ; pygidium punctate, with fine median carina ; prosternum rather narrow in front and gradually tapering to a sharp point at rear ; length "iV-^l mm.

The elytra are almost uniformly (except apex) rich dark reddish, the elevated lines showing as strong costae, the sutural and median being the most obvious casually and the latter extending nearly to the apex, and showing at its base a sharp prominent tubercle ; the reticulation is everywhere plain and becomes coarser at the apex. Suture is dentate, the sides of the body are nearly parallel, and show only a very faint compression behind the shoulders. The body below is very finely punctured in great contrast to the upper surface. Should be placed near lacordairei Jac, which it resembles in shape, but the dark color which shows on the elytra of that species as a spotted band entirely suffuses the elytra in gounellei. Clilaiiiys lutescens nov. sp. Stout, quadrate, luteous, rear of the thorax clouded with rufous-purple, and elytra with a common median rufous-purple spot and a vague cloud on either side, thoracic hump rounded, convex in front, declivous behind, with a row of about six tubercles set in a curve on the top edge of the declivity ; median sulcus behind wide and shallow, obsolete in front, about eleven or twelve tubercles on each elytron, the most prominent being a median subbasal and a sutural apical ; suture dentate ; presternum abruptly narrowed to about the middle, then narrow and parallel and thickly margined to obtuse end ; length 5.5 mm.

The hump is shaped as in deyrollei Jac. and ker^nes Lac. et a I., i. e., wide, convex in front, moderately declivous behind with a row of tubercles on the upper edge. The median sulcus is wide behind, feebly limited on the sides and passes between the two apical FRED. C. BOWDITCH. 13 tubercles, which are slightly curved backward at the apex. Beyond these it is defined by a slight ridge which speads out over the front in the shape of about two faint lines on each side and gradually vanishes. The elytra are thickly and finely punctate somewhat compressed behind the shoulders, each side having tubercles as follows : a small subsutural, the median subbasal above mentioned, which is easily the largest of all, blunt and obtuse, a line of five or six obliquely from the humerus to the suture back of the middle, the api- cal above mentioned, which next to the basal is the most prominent, and about four other small ones scattered about between the oblique line and the apex ; all of the tubercles of this line except the top one are rufous-purple, as are also some of the small ones at the rear, some of the punctures also are here and there purpled, pygidium very coarsely punctate, arranged in transverse lines, obsoletely carinate at bottom, sides of abdomen with a large swollen tubercle, body beneath coarsely reticulate.

Very close to amazonica Jac, but that species has only the antennae black, no other marks.

The following notes are the result of an attempt to sepa- rate in my own collection the species of this genus having simple claws. A small number of specimens have been con- tributed or loaned for study by Dr. Van Dyke, Mr. Frederick Blanchard, Mr. C. A. Frost and Mr. Percy G. Bolster, but the conclusions reached have been based for the most part solely on my own material. Some of these conclusions I have held to be in a measure tentative, but in this connection it is gratifying to add that an examination of upward of 500 specimens from the National Museum and Forestry Collec- tions, which unexpectedly came to me shortly after the com- pletion of this manuscript, has left the systematic conclusions virtually unchanged. This large collection has furnished, however, a considerable number of localities and some inter- esting biological data. The group of forms in the vicinity of gentilis is particu- larly puzzling and troublesome, owing perhaps to the greater or less instability of many characters generally useful in determining species. Certain individuals tend to bridge the gap between this species {gentilis) and some of the assumed varieties of lecontci, and a more thorough study of long series from many localities, coupled with a knowledge of life his- tories is needed here. In the following descriptions length of body is measured from the base of the beak to the tip of the elytra ; the point of antennal insertion is taken as the anterior basal extremity of the scape at the point of junction with the ball and socket joint. The types of all the new species described in this paper are in my collection. Our species may be primarily grouped as follows : TRANS. AM. ENT. SOC, XXXIX. 24 COLEOPTERA — RHYNCHOPHORA.

Antennae inserted at or slightly behind the middle in the cf , a little more posterior in the 9 , usually at or near basal two-fifths Subgroup gentilis. Antennae inserted distinctly beyond the middle in the cf, and at about the middle in the 9 Subgroup alutacea. Antennal club in the cf greatly elongate and thickly clothed with erect pile barbicornis.

Size large, 6 mm iliorio. First funicular joint much stouter than the second ; strial punc- tures of elytra larger, the intervals flat or slightly convex and from one to two times as wide as punctures at middle of disk ; body beneath rather sparsely finely punctate ; size smaller, 3-4| mm liispoides. Elytral intervals narrower than the striae ; punctuation coarse ; size 4|-5| mm perforatus. Group LECONTEI. Subgroup lecontei.

Femoral tooth obtuse, rudimentary, antennae (c?) inserted very slightly behind the middle of the beak, second funicular joint much less than twice as long as wide vitiosa. Femoral tooth acute, well developed, Elytral striae lightly or scarcely impressed, the intervals nearly flat. Beak in cf fully as long as, and in the 9 distinctly longer than the prothorax gentilis. Beak in cf evidently shorter than, and in the 9 subequal in length to the prothorax ; eyes a little less distant ; entirely black, surface duller and more rugose proxiiiia. Elytral striae rather strongly impressed, the intervals distinctly convex striata. Subgroup alutacea.

Reddish-brown, opaque, head very densely punctured, antennae (9 ) inserted distinctly beyond the middle of the beak, funicle stout imbellis. M. cuneforniis Horn. The type of this species is from Nebraska and is in the Ulke Collection. At the time of its description by Horn no other specimens were known, but there are now in his collec- tion examples from Colorado, Montana and Washington. Snow records it from New Mexico, and my own specimens were taken in the San Bernardino Mountains of California. Horn merely says in his description " surface blue," but in all examples known to me (I have not seen the type) the prothorax is nearly or quite black, the elytra dark blue.

(4) 26 COLEOPTERA RHYNCHOPHORA. hairs of the under surface are entirely simple, even upon the episterna, which are so often clothed with radio-pectinate hairs in this genus. M. lliorio n. sp. — Rather strongly cuneiform black throughout, lustre dull, above glabrous, beneath with sparse fine hairs, a few of which become radio-pectinate on the sternal side pieces. Beak (c?) evenly moderately arcuate, three-fourths as long as the head and prothorax, evenly rather closely punctate, a short smooth line above the insertion of the antennae, Antennae inserted at basal three-sevenths, scape reaching the eye, first and second funicular joints subequal, each a little less than twice as long as wide, the second about as long as the third and fourth together. Head moderately punctate, a small fovea or impressed puncture between the eyes, the latter rather flat and separated by about three-fourths the width of the beak. Prothorax conical, as wide at base as long, sides nearly straight, suddenly con- stricted at apex, surface densely rather coarsely punctate, without trace of median impunctate line. Elytra gradually widening to apical third, where they are one-half wider than the greatest thoracic width ; strial punctures rather fine, striae not impressed, intervals wide, fiat, interstitial punctures fine, forming a single line on the eighth inter- space, more or less irregular or double on the others. Body beneath densely punctured. Length 6 mm. Santa Rita Mountains, Arizona (Snow); Chiricahua Moun- tains, Arizona (Hubbard and Schwarz); Magdalena Moun- tains, New Mexico (Snow). The type is a c? from the first named locality, and has the abdomen concave at base, the median portions of the last three or four segments clothed with numerous short erect hairs. It differs from aineifortnis by its color, dull lustre, finer less impressed elytral series and wider intervals. M. hispoides Lee. This species is quite out of place in the Check List, doubt- less because Le Conte in his description made no compari- sons with older forms ; the simple femora and claws, how- ever, at once declare its position. It is very widely diffused, occurring from. Maine to British Columbia (type locality) and extending down into New Mexico and California. Some variation exists as might be expected in so wide a range, the Californian specimens showing a tendency toward a H. C. FALL. 27 greater width and convexity of elytral intervals than in the more northern and eastern specimens. The species is known to me from Kineo, Maine ; White Mountains, New Hampshire ; Brookline, Mass. ; Port Huron, Mich.; "Canada;" Porvenir, New Mexico; British Columbia, and Lake Tahoe, California. Ulke records it in his District of Columbia List as occurring on pines. The species re- ferred to by Bowditch in his Mt. Washington List as " n. sp. near hispoides,'" and that taken by Schwarz at Garland and Veta Pass, Colorado, and listed by Le Conte as " sp. near hispoides" will, I suspect, prove to be no more than slight variations of this wide spread species. M. perforatus Horn. A well known species, easily recognized by its very coarse, deep, dense sculpture, with unusually narrow elytral inter- spaces. The antennae are said by Horn to be median, but are really post-median in both sexes, as in all the species of this group. It occurs all the way from New Hampshire to Georgia (type locality). There is a Michigan specimen in the Horn Collection, and it is recorded in Wickham's Iowa List. M. lecontei Horn. Several distinct species are included under this name in collections, those in my own collection being easily differenti- able by the characters in the preceding table. Of these the true lecontei is much the largest, specimens under 4 mm. in length very rarely occurring, while this size is seldom if ever attained by any of the allied species. Lecontei is rather com- mon in the Rocky Mountains and westward, but does not, so far as I know, cross the plains to the east. Horn in his de- scription says " Kansas to Oregon and California," and it would be interesting just now to know the precise locality and identity of his Kansas specimens. Aside from the very obvious differences in size and color, two other characters may be mentioned which separate le- contei from other species of this group. The second funicu- lar joint is unusually elongate, being fully twice as long as TRANS. AM. ENT. SOC. , XXXIX. 28 COLEOPTERA RHYNCHOPHORA. wide and as long as the two following. The lengths of the funicular joints are subject to a little individual variation, and occasional specimens may prove disconcerting ; the dif- ference is, however, perfectly obvious in a series. Again, the elytral interspaces in males of lecontei and in both sexes of the related species show a single line of interstitial punc- tures with rarely any marked tendency toward irregularity ; in females of lecontei, however, the interspaces are unusually wide, the interstitial punctures small, and on several of the intervals form confused or double lines. Three color varieties are thought worthy of distinctive names. Prothorax dark purplish-blue, elytra violaceous, varying to entirely brilliant green siiperba new var. Color entirely black tenebrosa new var. Black, elytra dark blue or bluish-black tiiictipeiiiiis new var. The former {superba) is known to me from Arizona (type cf from Prescott), the second {tenebrosa) , type sex doubtful, from Porvenir, New Mexico, Colorado and California ; the last from Cloudcroft, New Mexico, and Williams, Arizona. Of these tinctipennis is most aberrant, and may possibly prove distinct; there seems, however, to be a gradual approach to the typical form. M. COilvexicollis u. sp. — Smaller and a little narrower than lecontei, cuneiform, black, the elytra bluish, moderately shining. Beak (c?) longer than the prothorax, strongly evenly curved, punc- tured as in lecontei. Antennae inserted at basal two-fifths of the beak, second funicular joint distinctly less than twice as long as wide and shorter than the two following together. Prothorax strongly longi- tudinally convex, fully as long as wide, sides broadly nearly evenly rounded, not much more strongly so in front ; apical constriction feeble, surface densely rather coarsely punctate without trace of smooth median line. Elytral striae well impressed, intervals rather narrow and convex, each with a single line of moderately strong punc- tures. Body beneath as in lecontei, the hairs more uniformly com- pound. Femoral tooth acute but not large. Length 3) mm. ; width 1.35 mm. Type. — c? ; San Bernardino Mountains, Southern Califor- nia ; 5000 feet. H. C. FALL. 29 Easily separable from lecontei by the small size, somewhat narrower form, more convex thorax, which is less narrowed anteriorly, short second funicular joint and more strongly impressed elytral striae, with narrower more convex inter- vals. The smooth median prothoracic line is very rarely entirely lacking in lecontei. M. austera n. sp. — Dull black, elytra rarely with faintest suspicion of blue, prothorax wider than long, apical constriction strong, surface densely punctate, without or with but slight trace of short median smooth line; elytra parallel or nearly so in the c?, a little widened behind in the 9 ; striae of coarse oblong punctures, scarcely or feebly impressed, intervals nearly flat with single lines of rather coarse inter- stitial punctures ; femoral tooth small but acute. Length 3-4 mm. The type of this species is a 6^ from Ridgeway, Ontario, sent me many years ago by Mr. A. H. Kilman. Other ex- amples before me are from " Canada;" Maine (Monmouth — Frost); New Hampshire (Farmington); Massachusetts (Con- cord and Framingham); Michigan (Marquette, Detroit, Port Huron); North Carolina (Retreat); New York; Ontario (Toronto). The small size, dull black or nearly black color, with rela- tively rougher surface sculpture, and more parallel elytra separate this species from typical lecontei easily enough. The following form in typical specimens differs so much from typical anstera as to present the appearance of a distinct species, which, indeed, I at first supposed it to be. With in- creased material intermediate forms turned up, and with present light I can give it varietal standing only. M. anstera var. substrig'a n. var.— Black, elytra dark blue or greenish, moderately shining, evidently but not strongly widened posteriorly. Prothorax closely punctate, the punctures becoming more elongate toward the middle, where they are more or less conspicuously longitudinally confluent. Second funicular joint less than twice as long as wide and shorter than the two following united ; elytral striae evidently impressed, but with the intervals nearly flat, and with single series of moderately coarse interstitial punctures. Length 3.2-4 mm. Massachusetts (Tyngsboro — type, cf, Dover, Brookline); New York (Peekskill). The strigose or substrigose prothorax primarily separates TRANS. AM. ENT. SOC. , XXXIX. 30 COLEOPTERA RHYNCHOPHORA. this variety from typical ausiera. In addition, the elytra seem to have normally a distinct blueish or greenish lustre, to be rather more widened posteriorly and to have the striae more evidently impressed. The form of body is nearly the same as in lecontei, but the size, color, shorter second funi- cular joint, more evidently impressed striae and single regu- lar series of larger interstitial punctures in the 9 , are quite sufficient for its separation, even if the locality label is not conclusive — as seems probable. M. vitiosa n. sp. — Black, lustre dull, elytra a little wider behind in the cf, distinctly so in the 9. Beak subequal in length to the pro- thorax (c?), slightly longer (9), moderately arcuate, closely rather coarsely punctate. Antennae inserted slightly behind the middle, second funicular joint short, obviously less than twice as long as wide. Prothorax a little wider than long, sides subparallel in basal half, rounded anteriorly with a moderate apical constriction ; punctuation dense, without or with but slight trace of smooth median line near base and apex. Elytral striae scarcely impressed, intervals nearly flat and with single series of rather coarse interstitial punctures. Femoral tooth rudimentary, nearly obsolete on the hind thighs. Length 3.1- 3.3 mm. Type. — 6^ ; Lake Tahoe, California. M. geiitilis Lee. This species was described from two examples collected by Crotch at Lake Tahoe. The type is a cf , 4 mm. long, and differs from vitiosa in having the elytra blueish and evi- dently smoother and less dull, thorax with entire smooth median line, the femoral tooth large. The second example is apparently a 9 , considerably smaller and possibly not identical with the cf type. The second funicular joint is not quite twice as long as wide in the type and is still shorter in the smaller 9 , in which it is nearly as in vitiosa. The rela- tive dimensions of the antennal joints are, however, subject to some individual variation and are not to be depended on except in series. I am placing as gentilis provisionally a number of examples taken by Dr. Fenyes at Lake Tahoe, which have the second funicular joint more slender, nearly or quite twice as long as wide, but which agree fairly well with the type in nearly all other characters. I am also com- H. C. FALL. 31 pellecl to place here for the present sundry examples from other regions, namely, specimens from Paris and Kinco, Maine, collected by Frost and Fenyes respectively, a cf from Fitzwilliam, New Hampshire (Blanchard), a cf from Mt. Washington, New Hampshire (Dimmock), and a 9 from Greenbush, Saskatchawan, contributed by Mr. T. N. Willing and bearing the name subtincta and the legend "emerged from spruce Apr 13 '06." These examples exhibit more or less trifling differences from typical gcntilis and from each other, but it is absolutely impossible to define them specifically with the limited material at hand. M. proximan. sp. — Black, surface lustre dull, elytra feebly widened behind in the cf , distinctly so in the 9 . Beak (cf ) short, scarcely as long as the prothorax, antennae inserted very near the middle ; in the 9 the beak is subequal in length to the prothorax, with the antennae inserted about two-fifths from the base. Second funicular joint scarcely twice as long as wide and rather shorter than the next two. Prothorax densely punctate, smooth median line very narrow but entire or nearly so. Elytral striae scarcely or but feebly impressed ; interstices nearly flat, for the most part with single regular series of moderately coarse punctures. There is a little tendency to irregularity on the second and third interspaces ; on the first and ninth the irregu- larity is obvious, as it is to a greater or less extent in all the species here considered. Femoral tooth moderate. Length 3.6-4.2 mm. Type. — d^ ; from Santa Clara County, California (C. F. Baker); Humboldt County, California (H. S. Barber). The eyes in the male type are separated by scarcely more than two-thirds the width of the beak. In gentilis the dis- tance is a little greater, about three-fourths the width of the beak so far as observed. M, striata n. sp. -Black, moderately shining, gradually wider behind. Beak as long as the prothorax in the cf , closely punctate, with the antennae inserted just behind the middle. In the 9 the beak is a little longer and less densely punctate, the antennal insertion at about the basal two-fifths. Second funicular joint nearly twice as long as wide, but scarcely as long as the next two. Prothorax densely punctate, median smooth line sometimes entire, usually more or less imperfect, and occasionally nearly wanting. Elytral striae rather deeply impressed, the oblong punctures in consequence ill-defined. Intervals convex, coarsely uniseriately punctate. Length 3^-4 mm. TRANS. AM. ENT. SOC. , XXXIX. 32 COLEOPTERA RHYNCHOPHORA. Type. — cf . Described from a good series taken on Mt. Wilson in southern California. This, by the more shining and uniformly rather deeply striate elytra is the best characterized species of the gentilis group. As in proxima the eyes in the c? are separated by scarcely more than two-thirds the width of the beak, and thus make an approach to aliitacea, in which the approxima- tion is still closer. In the 9 of striata the eyes are distant about three-fourths the rostral width, the sexual disparity in this respect being rather better marked than in any other of the allied species. E. alutacea Lee. Beak in the 6^ stout, alutaceous and opaque, a little wider beyond the base of the antennae, which is at about the apical third. In the 9 the beak is more slender, less dull, the an- tennae inserted at the middle. The eyes are less widely separated in the d^ than in any species of the preceding groups, their distance apart being about one-half the width of the beak in the cf and three-fourths in the 9 . In all the preceding species the eyes are separated by approximately three-fourths the width of the beak in both sexes, the sexual disparity being at most but slight. In striata and proxima the eyes seem to be a trifle closer than in the other species of the subgroup. Le Conte's description of alutacea is based upon two specimens, both 9 's, one from the Colorado Rockies, the other from Isle Royal, Lake Superior. The first named bears the label and is to be considered the type. It is alutaceous with a rather smooth silky lustre (under low power), the elytral intervals rather wide and flat, the striae unimpressed. In the Isle Royal specimen the striae are slightly impressed, thus approaching somewhat gentilis in appearance. In some examples from California and Oregon the striae are obviously a little impressed and the sculp- ture rougher, but these variations are gradual and not con- fined to particular regions. From gentilis and from black examples of lecofitei (var. tenebrosa), alutacea may in the ab- sence of cf's be distinguished by the relatively longer and more slender basal joint of the hind tarsi. The much more H. C. FALL. 33 basal insertion of the antennae in 9 's of lecontei will, of course, make separation easy, but in d^'s of lecontei and espe- cially mgenfilis this difference is less marked. In distribution as well as in degree of interspecific varia- tion, ahctacea rather closely parallels hispoides. Examples are known to me from New Hamphire, Lake Superior, Rocky Mountain region from Alberta (Bannf) to New Mexico at altitudes of 9000 to 11,000 feet in Colorado and New Mexico, British Columbia (Emerald Lake); Vancouver; Oregon (Portland) and California (Lake Tahoe, Kings River and Santa Monica). M. iinbellis Lee. A single 9 from Sonoma County, California (Van Dyke Collection), is before me. The type— a unique 9 — was from Oregon. The species may be at once known by the tabular characters. In the specimen at hand the third and fifth elytral intervals are wider. M. barbicoriiis Latr. This European species is included on the basis of a speci- men from Long Island (New York) in the Linell Collection, and a small series taken on elm at Dorchester, Mass., by Mr. Percy G. Bolster of Boston. The latter specimens have been taken recently (June, 1909), but the Linell specimen must have been found many years ago. The cf of barbicornis (I have not seen the 9 ) is at once known by the dense erect pile of the antennal club and two outer funicular joints, the club itself very elongate — as long as the entire scape and funicle. The beak is short and stout, about as long as the head, dilated beyond the antennal insertion which is at about the middle of its length ; thighs not toothed ; size rather small. The species of Magdalis with toothed claws are less numer- ous than those with simple claws and will not now be treated at length; the following notes, however, may be of service, and will probably be sufficient for their separation. Of the nine species known, six occur in the eastern United States, TRANS. AM. ENT. SOC, XXXIX. (5) 34 COLEOPTERA RHYNCHOPHORA. and three on the West Coast, one of which ranges as far east as Montana, Colorado and New Mexico. Of the western species — gracilis, aenescens and subtincia — the first two are distinguished by the very densely punctate thorax and the obvious pubescence of the upper surface, the scutellum quite densely clothed. They are very closely allied, and dependence seems to have been placed entirely on the aeneous surface lustre of aenescens. This is feeble or entirely wanting in some specimens, which then are not dis- tinguishable with certainty from gracilis by any characters that I can discover. In general it may be said that the elytral striae are less deep and the intervals less convex toward the suture, with a slight tendency to alternation in convexity posteriorly in aenescens, but these characters fail more or less completely in some examples. \ng7'acilis the striae are uni- formly deep, the intervals convex and uniform so far as I have observed. Aenescens occurs from southern Alaska to northern California. Gracilis is found in the vicinity of San Francisco and also in western Nevada if I have correctly referred a number of specimens taken at Reno by Professor Wickham. Subtincta differs from the two preceding by the more coarsely and less densely punctured thorax, and in none of the specimens at hand is there any obvious pubescence on the upper surface. The type locality is Gilroy, California, a little south of San Francisco, but the species is quite widely dispersed. It is known to me from many localities in Califor- nia ; from Oregon; Washington; Vancouver Island (Vic- toria); Montana (Kalispell); Colorado and New Mexico (Pecos and Ponil Canon). Specimens taken by me on alders in the San Bernardino Mountains of California are evidently more shining than the type, but the differences seem to me no more than racial. In a Pasadena specimen the elytra are faintly greenish, in others there is a barely perceptible bluish tint, but the majority, including the type, are black or very nearly so. Of the eastern species olyra is easily known by the distinct ochreous pubescence of the upper surface, the densely pubes- H. C. FALL. 35 cent scutellum, and in the great majority of specimens by the testaceous or piceo-testaceous antennae, tibiae and tarsi. Pandura and inconspicua are small species with broad head and relatively sparsely punctured thorax, elytra rather con- spicuously dilated posteriorly ; black throughout with dull lustre. They are very similar to each other, but differ by the hind angles of the prothorax, which are broadly lamini- form in patidura, much less expanded in inco7ispicua. In pandura the elytral intervals are typically flatter than in in- conspicua, but this character is apt to fail ; the surface lustre is also somewhat duller as a rule. In the remaining species — sal ids, barbita and armicollis — the head is elongate conical and the prothorax densely punc- tate. Salicis is the smallest of the three, and differs from the others in its non-protuberant mesosternum. The scu- tellum is not densely pubescent, the abdomen similarly punc- tate in the sexes and the antennal scape attains the eyes. Barbita and armicollis are as a rule much larger, though some males are very small. Both have the mesosternum protuberant, though Horn indicates this only for barbita, in which it is usually rather more pronounced. Barbita is en- tirely black with densely pubescent scutellum, and abdomen normally and similarly punctate in both sexes. The an- tennal scape lacks much of attaining the eyes in the 9 and barely reaches them in the cf . Armicollis is black with reddish or yellowish-brown elytra in the 6^, while the 9 is entirely reddish-brown; the scutel- lum is not distinctly pubescent, the antennal scape nearly attains the eyes in the 9 , and passes their anterior margin in the cf . This species differs from barbita, and in fact all our other species of the genus, in having the abdomen of the c? polished and impunctate along the middle, the smooth stripe limited on each side by a thin fringe of rather long and fine erect hairs. The terminal segment in this sex is truncate at apex with well defined though obtuse limiting angles. The distribution of the eastern species is as follows so far as known to me. TRANS. AM. ENT.

Very similar in general aspect and general structure to Magdalis, differing as follows : Upper surface moderately to rather densely pubescent, form more cylindrical, the elytra not at all widened posteriorly ; beak straight, much shorter than the prothorax, the latter strongly convex in profile, the hind angles not produced or expanded ; elytra transversely impressed before the apex ; fifth ventral segment as long as the two preceding or nearly so. The claws are simple and the femora unarmed, as in some species of Magdalis. Three Californian forms are known to me, all apparently very rare. The first to be described [fasciatus) may be re- garded as the type of the genus, but they are perfectly homo- geneous in all essential characters. T. fasciatus n. sp. — Brown, integuments rugose and dull, rather densely clothed above with coarse recumbent hair, which is bright red-brown on the elytra, orange-red at the anterior margin of the pro- thorax ; the basal half of the prothorax, base of elytra about the scu- tellum and beneath the humeral umbone, a transverse median fascia wider at the side margins, a lateral anteapical spot, and the apex whitish cinereous ; pubescence beneath whitish, the posterior half of the abdomen orange-red with some pale hairs intermixed, chiefly at the middle and sides. The white hairs of the under surface and those on the posterior parts of the pronctum are fine and conspicuously plumose. Beak rather stout, two-thirds as long as the prothorax, nearly straight, gradually widened apically, coarsely densely punctate and glabrous. Antennae inserted at about the apical two-fifths, scape curved, barely reaching the eye, first and second funicular joints about twice as long as wide, the second a little shorter and narrower than the first, third to seventh gradually shorter and slightly wider, the seventh a little transverse; club cylindro-conical, as long as the five preceding joints. Eyes not very convex, separated by a distance equal to two- thirds the width of the beak at apex ; a frontal puncture between the eyes. Prothorax as wide as long, sides strongly rounded, widest at middle, feebly constricted anteriorly, basal margin narrowly reflexed at sides ; surface densely but not coarsely rugose-punctate. Legs moderately stout, femora nearly simple, tibiae strongly unguiculate at apex, the outer angle also of the front tibiae produced in a short acute spur ; tarsi as long as the tibiae, penultimate joint bilobed ; claws small, simple. Length, 4-4.5 mm. ; width, L6-L8 mm. California: Pomona; Santa Monica; vicinity of San Fran- cisco. TRANS. AM. ENT. SOC. , XXXIX. 38 COLEOPTERA RHYNCHOPHORA. The type, and only example ever taken by me, was beaten fropi scrub oak in San Dimas Cafion near Pomona, April 30, 1892. A second example was taken at Santa Monica by Mr. Max Albright, from whom I received it. I have also seen an example in Dr. Blaisdell's Collection and another in that of Dr. Van Dyke, both taken near San Francisco. T. cousperilS n. sp. — Narrow, cylindrical, black, upper surface mottled with coarse fawn colored appressed hairs which are so ar- ranged on the pronotum as to leave the median line and a lateral spot each side subglaborus, and on the elytra are irregularly dispersed in small condensed areas ; vestiture beneath of the same color as above, the hairs broadly plumose except on the last three ventral segments and toward the anterior margin of the flanks of the prothorax. Beak about three-fourths as long as the prothorax, less densely and rugosely punctured than in the preceding ; antennae inserted slightly behind the middle. Last ventral shorter than the two preceding ; all else nearly as in fasciatus. Length, 5 mm. ; width, 1.85 mm. Type. — From Sylvania, California, April 4th. A single specimen received from Mr. L. E. Ricksecker. There are also single specimens in Dr. Blaisdell's and Dr. Van Dyke's Collections, taken near San Francisco. The slightly longer and smoother beak and more poste- riorly inserted antennae, with the shorter fifth ventral indi- cate that the type — and I think also the other two specimens — are females, and it has been suspected that this may be the 9 of the preceding species. There is, however, no direct evidence to that effect, and if it should so prove, will consti- tute an instance of sexual disparity in color and arrangement of vestiture quite unparalleled among the Rhynchophora. T. atratllS n. sp. — Slender, parallel, black, clothed sparsely and uniformly with fine whitish pubescence, the hairs plumose beneath as in the two preceding species. The beak is nearly three-fourths as long as the prothorax, coarsely densely punctate ; the antennae inserted a little beyond the middle ; the fifth ventral nearly as long as the two preceding. Length, 3.4 mm. ; width, 1.3 mm. Type. — From Alameda County, California. The unique type is doubtless a male, and differs much from fasciatus and conspersiis in its sparse fine whitish uni- formly distributed vestiture. In other respects it agrees with its congeners. H. C. FALL. 39 LIXUS Fab. L. inaritiinus n. sp. — Rather slender, parallel, black, slightly shining, not densely clothed with short cinereous hair, which is feebly condensed in the usual thoracic vittae, on the third elvtral interspace and in a broad sublateral vitta occupying intervals 7-9, but without nucleation at any part. Beak rather slender, nearly as long as the prothorax, at least in the 9 , not densely, finely punctate, with numer- ous coarser punctures toward the base ; a deep fovea between the eyes and a linear one between the antennae. First and second funicular joints equal in length, the first a little stouter. Prothorax nearly or quite as long as wide, sides parallel or very faintly convergent and nearly straight to apical fourth or fifth, then rather abruptly con- stricted; median line narrowly impressed, a little more broadly and deeply so behind ; coarsely and rather closely punctate, the interval finely closely punctulate. Elytra not quite two and one-half times as long as wide, but little wider than the prothorax and not quite three times as long, sides parallel in basal three-fifths, thence gradually narrowed, tip acutely not deeply notched ; elytral series not impressed, moder- ately coarse. Thighs feebly annulate; hind tibiae about three-fourths as long as the femora. Length (exclusive of beak), 6.7-10.4 mm.; width, 1.9-3 mm. Type. — From Santa Monica, California. Found about the roots of plants growing on the sand dunes immediately adjacent to the beach. I have long associated this species with semivittatus Csy. of Arizona and Utah, to which it is closely similar. The difference in habitat would certainly indicate specific distinction, and a closer study con- vinces me that this is the case. The chief differences oberv- able are as follows : There is never any trace of a vitta on the fifth interspace of the elytra in maritimus, the other vittae being at best feebly defined and evident only in well pre- served specimens. The beak is a trifle longer, the prothorax rather more densely punctured and the tibiae relatively a little longer, being about three-fourths as long as the femora, while in semivittatus they are about two-thirds as long. L. perloiig'us n. sp. — Very elongate, subcylindrical, black, feebly shining ; pubescence yellowish-gray, sparse and short on the thoracic disk, denser in a di-stinct moderately wide lateral vitta ; evenly nucleated throughout on the elytra, somewhat denser laterally but without well defined vitta. Beak cylindrical, moderately curved, not stout, a little longer than the prothorax, not at all carinate, rather finely and closely TRANS. AM. ENT.

Antennae inserted a little beyond the middle of the beak, first and second funicular joints equal, the first scarcely stouter, each equal in length to the third and fourth com- bined. Prothorax conical, nearly as long as wide, sides very feebly arcuate and regularly convergent from the base ; surface evenly con- vex except for a small feeble antescutellar impression ; punctuation fine and not very distinct, with sparser somewhat larger punctures inter- mixed. Elytra slightly wider than the thorax, three times as long as wide and almost four times as long as the prothorax, sides parallel and straight, humeral angles evident, disk with unimpressed rows of fine subelongate punctures. Legs rather slender, thinly and evenly gray pubescent. Length, 13.5 mm. ; width, 3.25 mm. Type. — From Chiricahua Mountains, Arizona. A single example of uncertain sex collected and given me by Mr. V. L. Clemence. This species is not very closely allied to any of our previously described species, but will go w^ith those species under " 10 " in Casey's table. It is more elongate than any other known to me. L. peuinsularis n. sp. — Moderately slender, subcylindrical, black, scarcely shining, evenly rather thinly clothed throughout with very fine, short cinereous recumbent hair, with a few sparse, short, but longer erect hairs visible in profile, especially on the declivity of the elytra. Beak (c?) about four-fifths as long as the prothorax, cylindri- cal, moderately stout, feebly curved, rather coarsely punctate, with intermixed finer punctures ; in the 9 as long as the prothorax, more slender and shining, with the apical parts finely and sparsely punc- tate ; median line obtusely prominent basally but scarcely carinate. Antennae inserted slightly beyond the middle Cc?), or a little behind the middle ( 9 ); first and second funicular joints subequal, each about as long as the third and fourth united. Head with sparse duplex punctuation, closer in the c? ; frontal fovea strong but small. Pro- thorax subquadrate, a little wider than long, sides just visibly conver- gent and straight, abruptly constricted near the apex; punctuation rather sparse and coarse, the interspaces finely densely punctulate ; basal impression small and feeble. Elytra a little more than two and one-half times as long as wide, just perceptibly wider than the pro- thorax and about three times as long ; humeral prominence very small and obtuse, sides straight and parallel in basal three-fifths, apex feebly narrowly notched, serial punctures moderately coarse. Pubescence beneath a little longer and denser than above. Length, 10.6-11.3 mm. ; width, 2.9-3.1 mm. Type. — cf ; from San Jose del Cabo, Lower California (Fuchs); one pair. H. C. FALL. 41 Rather closely allied to maritimus and semivittatus, but differing conspicuously by the perfectly uniform vestiture which shows no trace of condensation at any point, and by the slightly more robust form with the relatively somewhat wider prothorax, with sides more nearly continuous with those of the elytra. DINOCLEUS Csy. D. hystrix n. sp. — Oblong oval, not very robust, black, very densely clothed above with nearly white recumbent hair and numer- ous long fine, erect white setae, which on the elytra are subserially arranged on the interspaces; sides of beak, a broad dorsal thoracic stripe which is narrowed in front and finely divided, an elongate spot on the flanks, and several small elytral spots, subdenuded and blackish. Beak stout, not as long as the prothorax, dorsum flattened with vestiture so dense as to conceal the sculpture, but apparently not or but feebly carinate ; front broadly rather deeply concave. Pro- thorax nearly square, sides straight and parallel to the abrupt apical constriction, the angles not tuberculiform, punctures moderately coarse, deep and close. Elytra three-eighths wider than the prothorax and two and one-half times as long, nearly twice as long as wide, sides straight and parallel to apical two-fifths; serial punctures almost com- pletely concealed except the sutural row, not very coarse, larger in the small denuded spots which occupy the usual positions ; alternate inter- spaces not perceptibly more prominent. Beneath densely pubescent, finely speckled with black points ; legs bristling with longer hairs. Length, 8.5 mm. ; width, 3 mm. Type. — From Pasadena, California. Two examples col- lected by Dr. Fenyes in February. This is one of the most distinct species in our fauna by its dense white vestiture abundantly bristling with long erect hairs. In pi losus Q.nd. jacobinjis the elytral setae are long, but the alternate intervals are very strongly costiform in the former, while in the latter the setae are sparser and shorter and the vestiture generally darker, while in both the form is distinctly stouter and more oval. PHYLLOTROX Sch. In the Rhynchophora of North America* Dr. LeConte describes two small species which he doubtfully refers to P/iy/- lotrox. Whether either of these is a true representative of the * Proc. Am. Philos. Soc, XV, p. 174. TRANS. AM. ENT. SOC, XXXIX. (6) 42 COLEOPTERA RHYNCHOPHORA. tropical American Phyllotrox is still uncertain, but it may be stated as a fact that the two species described by LeConte — nubifer and ferrugineus — are at least subgenerically and prob- ably generically distinct, and that his series of nubifer in- volves two very distinct species, one of which is congeneric with the Floridian ferrugineus. The true nubifer is at once easily separated by its short feebly curved beak, finer elytral striae, which are usually more or less irregularly or con- fusedly punctured toward the base, the more densely punc- tate elytral interspaces and usually by the prothorax and elytral suture — especially toward the base, being more or less blackish — whence the name. In the undescribed form mixed with nubifer the beak is longer and more arcuate, the elytral striae coarser and regularly punctate throughout, the inter- vals more sparsely punctulate, the legs less stout, and the upper surface never with darker areas. As indicated above, these characters are shared with ferrugineus, and to these two may be added three other apparently distinct forms to be described below. With 7iubifer belongs the New Mexican quadricollis de- scribed by the writer,* and for these the genus Phyllotrox may be retained pending further information. Ferriigineus and allies are less in harmony with the preceding than they are with Euclyptus Dietz, to the generic description of which they conform closely and to the type of which — E. testaceus^ — they are very similar. The genus HyPoleschiis\ recently described by the writer is very near Euclyptus, differing chiefly in its sharply toothed claws, long second funicular joint and black color. In the species of the ferrugineus series the claws are merely thickened and obtusely angulate at base, while in nubifer and quadricollis they are quite simple. The two species of Phyllotrox known to me easily separate as follows : Size larger, prothorax relatively wider, beak a little shorter, antennal club longer than funicular joints 2-7, pygidial groove not attaining the apex (New Mexico) quadricollis. * Trans.

Last ventral segment moderately coarsely and closely punctate, nearly or quite as long as the two preceding in the 9 , and longer than the two preceding in the 6^ .

Size smaller, H mm. in length, the elytra rather less than one half longer than wide and about two and one-fourth times as long as the prothorax ferriigineiis. As compared with ferrugineus ^ the size in iestaceus is evi- dently larger, the prothorax is relatively a bit wider, the last ventral a little longer, being distinctly longer than the two preceding together ; the metasternum apparently more coarsely punctate, not clearly visible in ferjiigineus.

Beak (cf ) about as long as the prothorax, regularly moderately strongly arcuate, cylindri- cal, rather densely punctate, the punctures tending to become con- fluent longitudinally.

Scape nearly attaining the eyes ; funicle 7-jointed, basal joint obconic, nearly twice as long as wide, much wider than, and nearly twice as long, as the second, the latter similar in form but shorter, about one-third longer than wide and not quite as long as the next two; joints 3-7 short, gradually increasing in width, the 7th about half as wide as the club, the latter blackish, broadly oval pointed, about as long as the preceding five joints. Prothorax slightly longer than wide, sides broadly arcuate, subparallel basally, narrowed anteriorly and feebly constricted at apex, surface densely moderately coarsely punctate. Elytra three-fifths wider than the prothorax and nearly two and one-half times as long, two-thirds longer than wide, sides feebly arcuate or subparallel basally, discal striae regular, feebly impressed, closely rather coarsely punctured, intervals wider than the striae, nearly fiat, subbiseriately punctulate.

Last ventral (d^) longer than the two preceding, fiat, apex with a small apical notch ; in the 9 subequal in length to the two preceding, surface broadly flatly impressed at middle apically. Length, 1.9-2.4 mm. ; width, .8-1 mm. California— Santa Barbara, February (type, cf ), Lake Ta- hoe, July. Huachuca Mountains, Arizona (Wenzel). According to Dr. Van Dyke occurs on Ceanothus. In the Arizona specimens the pubescence is not so distinctly golden as in the typical Californian form. E. derivatus n. sp. — Very similar to the preceding, but separable by the sexual characters of the last ventral as given in the table. The pubescence is ochreo-cinereous rather than golden in the specimens before me, and there is a marked tendency for the head, including the beak, the prothorax and the greater part of the under surface to be- come darker or even piceous in color. The second funcular joint is shorter, barely perceptibly longer than wide, the outer joints wider and thinner, almost disk-like, the seventh two-thirds or three-fourths as wide as the club. Specimens were collected at Cloudcroft, New Mexico (type, 9 ), in June by both Viereck and Knaus. Two cf's among the Huachuca Mountains specimens sent me by Mr. Wenzel agree with these in the non-emarginate last ventral and antennal characters and doubtless belong here. E. equisectus n. sp.— Very similar in form and facies to the two preceding species, but with the surface, especially of the prothorax, more shining; color rufotestaceous, metasternum but slightly darker, ventral surface flavotestaceous.

Antennae inserted at apical two-fifths of beak, first funicular joint about twice as long as wide and longer than the next two, second similarly proportioned but much smaller, as long as the next two united ; following joints evidently transverse, the seventh not much more than half as wide as the club, the latter scarcely as long as the four preceding joints. Prothorax a little longer than wide, sides broadly arcuate, surface moderately strongly and closely punctate, the punctures well separated, however, the intervals shining. Elytra three- fifths longer than wide and about four-fifths wider than the prothorax, sides feebly arcuate and a little divergent from base to middle ; striae fine, intervals wide and very finely remotely punctulate.

The position of this species in the table is somewhat tenta- tive, the 9 being unknown ; it is, however, readily separated from rutilus and derivatus by its less robust form and less closely punctured and more shining surface. It is more like equisectus in these respects, but differs in the longer basal funicular joints, and somewhat in form as well as color. E. femigineus Lee.

The prothorax is barely as long as wide, elytra two and one-fourth times as long as the prothorax, and rather less than one-half longer than wide. I have seen no other specimen. ANTHONOMUS Germ. The following notes on the species of this and allied genera are to a considerable extent the result of a recent examina- tion of some of the types in the LeConte, and also in the W. G. Dietz Collection, now in the Museum of Comparative Zoology at Cambridge, Mass. A. pusillus Lee. In Dietz's Revison this species is recorded solely from Massachusetts. The unique type, as stated in the original description, was from Texas (collected by Belfrage), but by some accident has disappeared from the point and is doubt- less lost, as I looked carefully for it in the bottom of the box without success. There are, however, two Columbus, Texas, examples of pusillus in the general mixture of unplaced specimens at the end of the box, and these no doubt are pre- cisely like the lost type. The greater number of specimens of this species now in collections are probably from Massa- chusetts, where it has been taken in numbers near Lowell on Helianthemum canadense by Mr. Frederick Blanchard, who speaks of it at some length in Entomologica Americana, Vol. Ill, p. 87. A. liaiiiiltoni Dietz. So far as I can see, this differs irom pusillus only in having the scales a little yellower, and the subdenuded area of the elytra better defined. I should have little hesitancy in unit- ing them. A. vulpiuiis Dietz. I see no possible means of separating this from profundtcs Lee. There are perfect intermediates in size and color in H. C. FALL. 47 the LeConte series, and there is, I think, sufficient individual variability in the lengths of the funicular joints to cover the differences given by Dietz, which do not look as important in the specimens themselves as they appear on paper. A. rubidus Lee. The accessory cusp on the front thighs of which Dietz speaks in his table, is faintly indicated in the type, and is rather more pronounced in some examples of prohindus, in which both LeConte and Dietz say it is absent. The two species are, of course, quite distinct, but the accessory cusp is not to be relied upon as a distinguishing character. A. haeinatopus Boh. Both LeConte and Dietz have expressed themselves as pretty well satisfied that this is the same as sycophanta Walsh., and I am myself convinced of it. Bolteri Dietz and corifusus Dietz are exceedingly close to and, perhaps, only varieties of the above ; but of this I do not yet feel assured. A. bruiinipeniiis Mann. There is no very good reason for believing that the single example so identified by LeConte is the true brunnipennis. Mannerheim's description is very brief, but calls for an insect two lines long excluding the rostrum, finely pubescent, pitchy black with brown elytra. LeConte's specimen is a 9 , con- siderably smaller, uniform in color, and rather sparsely but truly squamose. Specimens taken by Mr. H. S. Barber at Blair's Ranch, Humboldt County, California, are apparently identical with the LeConte specimen, which was taken by Crotch at Geysers, California. This species should be placed near rmu^iniis of the squamos2is group, differing from the latter by its more coarsely punctured thorax, more unevenly disposed vestiture which is condensed on the median line and at the sides of the prothorax, and more or less at the middle of the fourth and toward the base of the sixth elytral intervals. I have seen a number of examples of the Californian moru- lus with brown elytra, and here the vestiture would fit Man- nerheim's expression " tenuiter pubescens," but the pro- thorax is not conspicuously " profunde rugoso-punctate," TRANS. AM. ENT. SOC, XXXIX. 48 COLEOPTERA RHYNCHOPHORA. the tibiae and tarsi are not ferruginous, at least in mature specimens, and the size is much too small. I have as yet seen nothing that fairly fits Mannerheim's description, and should be glad to hear from any collector who believes he has a good brjinnipefinis. A. melaucholicus Dietz. I have scarcely a particle of hesitation in pronouncing this and murhius of the squamosus group identical. Melancholicus is truly a squamose species and should be transferred to the sqtiarnosus group, replacing there the name murimis which becomes a synonym. I am unable to detect an appreciable tooth on the middle thighs in melancholiais, in fact, in this and all other respects they appear to agree, comparison being made between the two types, which are both 9 's. There is a second example of melaiicholiais — a cf, and with the 9 type of niurinus are two other examples which are probably not identical, one from Texas, the other from California (not Colorado). A. sulcifroiis Lee. This cannot be separated from musculus Say. It is not black as LeConte describes, but pitchy brown, the elytra at least very plainly so. I do not consider the form of the frontal fovea to be of much significance. It varies much in depth and distinctness and tends to become elongate in some indi- viduals when normally more or less punctiform. The narrow impressed line in the type of sulcifrons is probably accidental, as none of the other three placed in the series by Dietz have it — these at least would all make good mttsculus. A. sexguttata Dietz. Dietz says the front is sulcate in this species ; I found the fovea approximately punctiform in all the specimens of his series that I examined. A. albopilosus Dietz. I cannot remember whether any one has called attention to the small tooth on the inner edge near the apex of the hind tibiae in the c? of this species. The character is a unique one. H. C. FALL. 49 A. solani nov. sp. Very closely related to the aeneolus of Dietz with which it was confused by that author. The type of aeneolus is from Columbus, Texas. The Los Angeles and Arizona examples included by Dietz belong to the present species. This dif- fers most obviously from aeneolus in its somewhat broader form, and in having the prothorax narrowed from the base or very close to it, while in aeyieohis the sides are rounded in at base, the point of maximum width being at or near the basal third. The tarsi and the tibiae in outer half are rather conspicuously paler in ae?ieolus, only slightly so as a rule in solani. Dietz describes the antennae as inserted at about one-half from the apex. This is substantially accurate for the 9 's, but in the cf 's of both species, the point of inser- tion is about two-fifths from the apex of the beak. Solani has occurred in some numbers on Solanuvi nigrum near Pomona, California (type cf ), in October and Novem- ber. One specimen bears date "Apr. 23." This species was originally identified for me as aeneolus, and is the one so recorded in my So. California List. A. obtriisiis n. sp. — Uniformly piceous brown, moderately shining, clothed above conspicuously but not densely with pale ochreous squami- form hairs, which are condensed on the scutellum, somewhat on the median line of the prothorax, and in two posterior transverse elytral fasciae which nearly reach the suture and enclose a less pubescent area. Body beneath with similar squamiform hairs except on the ventral seg- ments, which are finely pubescent. Antennae testaceous, club pice- ous ; second funicular joint rather less than twice as long as wide, and about two-thirds longer than the following joint, which is very nearly as wide as long. Head sparsely punctulate. Beak a little longer than the head and prothorax, shining and punctate at apex, finely strigose and opaque with feeble lateral sulci behind the antennal insertion, which is at the apical two-fifths ; median line finety carinate ; front finely and feebly sulcate ; eyes separated by one-half the width of the beak. Prothorax one-half wider than long, sides distinctly arcuate, widest at about the middle, hind angles obtuse, apical constriction not strong, punctuation close and moderately coarse. Elytra one- fourth longer than wide, sides subparallel for three-fifths their length, striae finely impressed, moderately punctate; intervals feebly convex, not evidently punctate.

Described from a single 6^ example which seems to be most closely allied to sulciirons, but distinguishable by the coarser and denser vestiture, longer beak, paler antennae, and finer and less coarsely punctate striae. Since writing the above I have examined the LeConte and Dietz Collections, and have come to the conclusion, already expressed in a note on sulcifrons, that this latter is not sepa- rable from musculus, which name may therefore be substi- tuted for sulci fro7is in the above paragraph. The species which I have here described seems to be iden- tical with two Texan specimens included by Dietz with his vespertinus, the type of which comes from Jacksonville, Fla. In this type the frontal fovea is not obviously elongate (Dietz says sulcate in his description but foveate in his table), the vestiture is nearly white, surface lustre dull, not very coarsely pubescent above except in condensed areas, where the hairs are squamiform, but beneath they are more properly scales, and are very dense on the under side of the head and sides of the body. Above they are denser on the median line of the prothorax and in two transverse elytral fasciae, the anterior consisting of three spots occupying intervals 4-6-8, the poste- rior less distinctly defined but seemingly similarly formed. The insect is in good condition but apparently somewhat immature. In the two Texan examples which follow the type of ves- pertinus the vestiture of the upper surface is ochreous, more uniformly squamiform, the fasciae not evidently broken into spots ; vestiture beneath very much the same in character as above and not conspicuously more scale like, elytra dis- tinctly shining. Both specimens are 9 's, with the antennae inserted slightly beyond the middle of the beak. A. basidens n. sp.— Robust, oval, deep black ; antennae testace- ous at base, becoming gradually darker externally, the club piceous. Above subglabrous, the pubescence excessively short, fine and sparse, except for the scutellum and a small area of equal size posteriorly con- H. C. FALL. 51 tiguous to it on each sutural interspace which is densely clothed with white squamules ; beneath normally sparsely pubescent, the hairs fine on the abdomen, coarser on the sterna. Head alutaceous, opaque, finely sparsely punctate ; frontal fovea punctiform, eyes separated by scarcely half of the width of the beak, the latter as long as the front femora, coarsely striate almost throughout, the striae punctate ; an- tennae inserted at the apical two-fifths (c?) or just beyond the middle ( 9 ) ; second funicular joint not quite twice as long as wide, nearly as long as the next two ; third about as long as wide. Prothorax dis- tinctly transverse, sides arcuate and very little convergent in basal two- thirds, thence more strongly convergent and sinuate to apex ; hind angles a little obtuse ; punctuation close, moderately coarse, the inter- vals alutaceous and dull. Elytra short, not more than one-fourth longer than wide, three-fifths wider than the prothorax, sides nearly straight in basal half, striae rather coarse, well impressed and rather strongly punctate ; intervals convex, very minutely transversely rugulose, feebly shining, the hairs excessively short and fine ; basal margin with a transverse dentiform prominence at the base of the third interspace. All the femora acutely toothed, the tooth of the anterior femur larger as usual, acutely triangular and longer than wide ; tibiae straight; ungual teeth moderate, approximate at tip. Length 1.7-2 mm. Type. — cf ; from Santa Rosa, Lower California (Beyer). This species v^ill fall near ebeninus in Dietz's table, but is abundantly distinct from any other species known to me. The peculiar basal dentiform prominences of the elytra are characteristic and I think unique, at least so far as our fauna is concerned. A. obesiilus n. sp. — Very robust, black, above rather thinly clothed with elongate yellowish-gray scales which are more or less condensed and whiter in a median and sublateral vittae on the prothorax, scu- tellum densely clothed with white scales, also a short line of similar scales on the fourth just behind the middle and at the base of the sixth elytral interspaces ; beneath more densely albo-squamose, especially at the sides of the sterna, the vestiture of the ventral segments sparser and more hair like. Head numerously punctate, frontal fovea fine, linear; eyes separated by slightly less than the width of the beak. Beak rather slender, feebly curved, nearly half as long as the body, finely punctate, the punctures more or less confluent longitudinally, but without well defined striae ; lustre dull in basal half, more shining apically.

Elytra three-fifths wider than the prothorax, one-sixth longer then wide, sides parallel in basal half, striae rather finely impressed, moderately punctate ; intervals nearly flat, about three times as wide as the striae, sparsely punctulate and moderately shining. Second ventral segment distinctly longer than the third, the latter just visibly longer than the fourth, fifth as long as the third. Legs black, tarsi becoming piceous brown; all the femora apparently unarmed. Length, 2.3 mm. ; width, 1.4 mm. Type.— From Ormsby County, Nevada (Baker). The type is a 9 , and with it I place a cf from the same locality which is almost surely identical ; it is a little less robust, the vestiture a trifle sparser, the pronotal vittae obso- lete, and the short elytral vittae while evident, are much less conspicuous ; the front thighs have a barely visible obtuse tooth, the hind tibiae are slightly incurved at apex, but scarcely enough to throw the species into the subgenus Cnemoscyllus. If it were so referred, however, it is at once distinguishable from any of the species with 7-jointed funi- cle by its stouter form and sparser vestiture. The species seems best referred to the sguamostis group, from all of which it differs by its stouter form. The vestiture is sparser than in any of the species with nearly unarmed femora ; murimis approaches it in this respect, but in this latter the scales are unicolorous. A. appositus n. sp.— Rufopiceous ; legs, beak and antennae ru- fous ; body densely clothed with pale ochreous to brown, and whitish scales, the latter forming three conspicuous vittae on the prothorax, covering the scutellum, the fourth and sixth elytral intervals for the greater part of their length, intervals 8-10 in great part ; there are also numerous white scales on the sutural interval, and those of the under- surface are mostly of this color. Beak (cf ) longer than the head and prothorax, rather densely punctate and striate throughout ; dull and squamose basally, more shining apically. Eyes separated by a little less than the width of the beak. Antennae inserted at about the apical two-fifths of the beak in the cf, a little beyond the middle in the 9 ; funicle 7-jointed, second joint twice as long as wide, nearly twice as long as the third and subequal to the third and fourth united.

Ventral surface moderately densely scaly, the scales narrower than at the sides of the sterna, becoming hair-like at the middle of the fourth segment, the flfth truly pubescent. All the thighs armed with a small acute subspiniform tooth, less obvious but quite distinct on the posterior pair. Length, 3-3.2 mm. ; width, 1.4-1.6 mm. Type. — cf.

Closely related to iectiis, but differing in its longer second funicular joint and denser vestiture. It is still nearer to heterothecae Pierce, but is much larger and more conspicu- ously vittate than a specimen of the latter kindly sent me by Mr. Pierce. This specimen is 2,2 mm. in length, and this is the length given by Mr. Pierce in his description. In tectus the second funicular joint is normally short, very dis- tinctly less than twice as long as wide and much shorter than the two following united. A. tectus Lee. Dietz records as the habitat of this species — Arizona, New Mexico, Colorado and Utah. He has certainly confused two or more species under this name, none of which perhaps are the real techis, the unique type of which is from Massachu- setts. In the original description Massachusetts and Georgia are given as localities, but the representative from the latter region is not now in the LeConte cabinet ; possibly it inay be in the Horn Collection. The western limits of this spe- cies are as yet undetermined. Specimens from Belvidere, Kansas, sent me by Mr. Knaus are very close indeed to typi- cal tectus and I so place them, but the probability is great that specimens from the Rocky Mountains and further west are not identical with the New England type. Tectus has been taken in numbers in recent years at Tyngsboro, Mass., by Mr. Blanchard, who found it on wild asters (Diplopop- pus) in September. TRANS. .\M. ENT.

Specimens in no way distinguishable from the Montana type have been taken at Franconia, New Hampshire, in Sep- tember or October by Mrs. Slosson, who writes that they were swept from wild asters in a limited area. A, luiiuicailiis n. sp. — Moderately elongate, piceous ; legs, beak and antennae — except the club — rufotestaceous ; body very densely clothed with broad overlapping grayish-white scales which completely conceal the sculpture. Beak (c?) as long as the head and prothorax, moderately arcuate, not densely punctate, the punctures arranged serially toward the base; antennae inserted at apical two-fifths, funi- cle 6-jointed, second joint about twice as long as wide, one-half longer than the third and subequal to the second and third united. Eyes separated by slightly less than the basal width of the beak. Prothorax a little wider than long, sides parallel and broadly rounded in basal two-thirds, apical constriction feeble. Elytra obviously but not greatly wider than the prothorax, elongate oblong, sides parallel to behind the middle. Fifth ventral segment about one-half longer than the fourth, the latter equal to the third. Front thighs minutely toothed ; hind tibiae straight ; claws small with a short acute basal tooth. Length, 1.7-2.2 mm. ; width, .7-. 9 mm. Type. — d" ; from Tuscon, Arizona (Wickham). Very similar to canus but a little stouter, the hind tibiae not curved in the cf , the last ventral less elongate and the claw tooth slightly shorter. Because of the unmodified hind tibiae of the 6^, jnimicanus rmxsi be referred to the squamosus group in which it is to be associated with pauperculus by Dietz's table. A. latiusculus Dietz. I cannot for a moment accept this as distinct from subfas- ciatus Lee. The distinctive characters given by Dietz are no more than individual. As illustrating the failure of the tabular characters, a North Carolina specimen in my collec- tion would by the elytral fascia be latiusculus, but by the frontal fovea would be subfasciatus. A. moleciilus Csy. I can see no means of separating this from robushilus Lee. According to Casey moleciilus differs in its "narrower form and slightly different vestiture ; " according to Dietz mole- H. C. FALL. 55 cuius is " closely allied to robustuhis with which it agrees in form and vestiture." In LeConte's description of robustulus the thighs are said to be not toothed, and the second and third funicular joints equal or nearly so. Casey describes moleculus as having the front thighs toothed and the second funicular joint longer than the third. The front thighs are really toothed in robustulus — LeConte was in error here — while the second funicular joint is, or is not, appreciably longer than the third according to the individual specimen one is examining. As Casey described from an unique he could not know this, but it is equally true in a series of both eastern and western specimens, and here as well as in many other species the variation is in some degree sexual. The characters given by Dietz for separating moleculus from robustulus are in part individual and in part non-existant ; e. g. he says that the second and third funicular joints are together longer than the next three in robustulus, which is not true. A. spliaeralciae n. sp.— Elongate oblong, piceous, beak, an- tenae'knd legs bright rufous, vestiture exceedingly dense both above and below, consisting of pale ochreo-cinereous scales which are on the average about twice as long as wide, almost perfectly uniform in color above except along the median line and at the sides of the prothorax, where they are whitish. The scutellum is densely white, and there are barely perceptible traces of short paler vittae on the sutural, fourth, and sixth elytral intervals, Body beneath very densely clothed through- out with whitish scales, wider at the sides of the sterna, and narrower but not hair-like on the ventral segments. Antennal funicle 7-jointed, second joint nearly twice as long as wide and not much shorter than the two following joints united. Eyes and beak nearly as in appositus. Prothorax very nearly as long as wide, subconical, apical constriction feeble. Front femora with a small acute tooth, middle and hind femora apparently unarmed. Hind tibiae (c?) straight, with a rather feeble parallel sided dilatation in apical fourth. Length, 3 mm. ; width, 1.3 mm. The type is a c5^ from Phoenix, Arizona, taken on Sphaeral- cea variabilis by Prof. Cockerell. With the type I associate single specimens from Santa Rita Mountains, Arizona ; Pike's Peak and Boulder, Colorado ; Wallace, Kansas ; and Dakota. TRANS. AM. ENT. SOC, XXXIX. 56 COLEOPTERA RHYNCHOPHORA. These all agree in bodily form, and the cf' s (Pike's Peak and Wallace, Kansas), agree in the form of the hind tibiae. In none of these is the vestiture quite so dense as in the type, and there is some small variation in the relative lengths of the second and third funicular joints, the second being distinctly shorter and not much longer than the third in the Dakota example. Some of the other specimens are, how- ever, intermediate in this respect, and its value therefore seems doubtful. Sphaeralciae should be referred to the sub- genus Cnemocylhis because of the modified cf hind tibiae, which, in fact, are precisely of the same type as in helianthi. This latter is a stouter species, with whiter vestiture, which is more hair-like toward the abdominal apex, and with more elongate second and third funicular joints. I have recently seen specimens of sphaeralciae placed with hirtus in the Dietz Collection. In this latter species the scales are narrow and linear, in fact LeConte in his description speaks of the vesti- ture as "coarse scarcely squamiform pubescence." A. cycliferus n. sp. — Narrowly oval, piceous, legs and antennae rufous, club fuscous ; clothed very densely throughout with overlapping broadly oval or nearly circular white scales, intermixed with scattered darker scales varying from pale brown to blackish purple in color, these darker scales aggregated most noticeably in two imperfect discal pronotal vittae and in an elongate discal elytral spot at about the poste- rior third, and less evidently in a subbasal spot on either side of the suture. Beak about one-fourth longer than the prothorax, polished and rather finely sparsely punctate, subsulcate at sides basally, base squamose for a short distance. Antennae inserted at about two-fifths from the apex in the 6^ , just perceptibly beyond the middle in the 9 ; second funicular joint as long as the next two (c5^), distinctly less so (9), the third and fourth joints each a little longer than wide, the third slightly longer than the fourth. Prothorax three-fourths as long as wide, sides broadly arcuate and subparallel in basal half, moder- ately convergent and evidently though not strongly constricted apically ; surface completely concealed by the vestiture. Elytra at base very little wider than the thorax, gradually feebly wider posteriorly, widest at about the middle ; striae invisible. Front thighs with a small acute tooth, middle and hind thighs not visibly toothed. Front and middle tibiae slightly incurved at apex in both sexes ; hind tibiae regularly and more strongly curved in the cf, nearly straight in the 9 . Ungual teeth short and not approximate at their tips. Length, 2.3-2.6 mm. ; width, .85-1 mm. H. C. FALL. 57 The type is a cf from St. George, Utah, collected by Prof. Wickham. With it I have placed several 9 's from Milford. Utah, also collected by Wickham, which are doubtless identi- cal although they differ constantly in the relatively shorter second funicular joint. A 9 specimen labelled Santa Cruz, California, is perfectly similar to the Utah ones except in its larger area of dark scales, and is placed with them ; there is possibly an error in locality. This species is a Cnemocylhis and may best follow canus, from which it differs by its narrower form and intermixture of dark scales. A. tenuis n. sp. — Also a Cnemocyllus. Very similar in form and vestiture to the preceding species, the differences of moment being as follows : The size in series is distinctly smaller, the general form even narrower, vestiture white throughout, and in some examples at least, a little less dense ; all of the femora apparently unarmed ; hind tibiae of cf less strongly curved ; claws with longer teeth which are approxi- mate at tip. Length, 1.6-1.9 mm. ; width, .65-. 75 mm. Type. — A cf from Ormsby County, Western Nevada (Baker). Other localities represented are Goldfiield, Nevada (Nunen- macher); Chad's Ranch, Utah (Wickham); Pocatello, Idaho (Wickham); Bridgeport, California (Wickham); Santa Cruz, California, this last locality open to doubt. This is one of the species that passes as nanus {=^can7is) in collections. The true nan7isis not so narrow. It was de- scribed from Texas, and probably does not occur at all in the region occupied by the present species. A. jlllictlirvis n. sp. — Moderately elongate, parallel, brownish, clothed above with subcontiguous broadly oval to narrowly oval feebly contracting dull ochreous and pale brown scales, which are larger, paler and somewhat denser in three thoracic vittae, alternating with two broader stripes of narrower brownish scales. Elytra uniformly clothed with pale ochreous scales which are barely visibly denser at the middle of the fourth and toward the base of the sixth interspaces ; beneath, sterna quite densely clothed with broad scales, the ventral segments with sparser narrower scales. Beak about one-fourth longer than the prothorax, moderately coarsely punctate striate, median line narrowly smooth and feebly cariniform behind the antennal insertion. Head squamose ; eyes separated by a little less than the basal width TRANS. AM. ENT. SCO. , XXXIX. (8) 58 COLEOPTERA RHYNCHOPHORA. of the beak. Antennae inserted at about the apical two-fifths of the beak ; funicle G-jointed, second joint a little longer than the third, this slightly longer than the fourth. Prothorax moderately transverse, the sides broadly arcuate and convergent anteriorly, apical constriction broad and feeble, punctuation strong and dense. Elytra four-fifths longer than wide, one-fifth wider than the prothorax, sides straight and parallel for more than half their length, apex rather narrowly parabolically rounded ; striae moderate, rather coarsely punctate basally, the intervals slightly convex. Femora unarmed ; hind tibiae sinuate interiorly but not visibly bent ; claws armed with very short but finely acuminate basal teeth which are not approximate at tips. Length, 2.15 mm. ; width, .8 mm. Type. — From Ensenada, Lower California. A single cf specimen. The derm throughout is brownish in color and may possi- bly indicate immaturity. The last ventral segment is but little shorter than the two preceding united. Although the hind tibiae are not visibly bent, the general aspect is that of Cnemocyllus and its place is apparently near ligatus, which Dietz placed in this subgenus for like reasons. According to Dietz the claws in legahis are armed with a short obtuse tooth, and the elytra show a dark "denuded fascia" extending from the sides to the fourth interspace; the elytra are also both by description and in the figure more nearly equal to the prothorax in width than in the present species. In an El Paso, Texas, specimen which I have con- fidently determined as ligatus, after comparison with the Deitz Collection, the vestiture is very dense, the scales more or less overlapping throughout. A. canusLec, A. affiuis Lee, A. nanus Lee. After repeated and careful examination of the types of these three supposed species I am pretty well convinced that they constitute but a single species. They are all from the same source and very probably from the same locality, and there appear to be absolutely no differences except size and relative length of the second funicular joint. The LeConte Collection contains the following representatives. Canus.—OrvQ cf, 2.3 mm. long excluding beak, hind tibiae rather feebly nearly evenly curved, second funicular joint as H. C. FALL. 59 long as the next two, last ventral not much shorter than the two preceding united. LeConte's original description calls for four specimens, but the collection now contains only the unique type here briefly characterized. A{{inis.—Ty\ie 9 , 1.95 mm. long, hind tibiae straight, second funicular joint a little longer than wide and a little longer than the third, but evidently shorter than the next two ; last ventral distinctly shorter than the two preceding. Second example — a cf — 2 mm. long, agreeing with ca/ms except that the second funicular joint is shorter, about one- half longer than wide, and relatively longer than in the first example though shorter than in canus. Third example — 9, 2.1 mm. long, second funicular joint twice as long as wide and four-fifths as long as the two fol- lowing. A^«««^— Type, 9 , 1.6 mm. long, virtually identical in an- tennal formation with type of affinis. The types of canus and affinis have the scaly covering pretty well preserved and seem to be uniformly white ; all other examples are much abraded, but the scales are large and white in all specimens. The namis of the Dietz Revision and of most collections is not the true nanus of LeConte, but either the A. tenuis or the Epimechus gracilis of the present paper. Neoniastix punctiilatus Dietz. Dietz expresses a doubt of the distinctness of this from solidaginis. I believe his suspicions are well grounded and should call them identical. EPIMECHUS Dietz. E. gracilis n. sp. — Form very narrow and elongate, black, antennae — except the club, — legs and sometimes the beak rufous or rufotestace- ous ; vestiture dense, white throughout, consisting of large broadly oval or rounded more or less overlapping scales. Beak ( cf ) but slightly longer than theprothorax, shining, squamose at base, finely not densely punc- tate,, substriate laterally. Antennae inserted at the middle of the beak in the cf, funicle 6-jointed, second joint a little longer than the third but evidently shorter than the next two together. Prothorax evidently wider than long, widest at or a little behind the middle with the sides moderately arcuate, or with the sides subparallel and very feebly arcu- TRANS. AM. ENT.

Elytra very slightly wider at base than the prothorax, twice as long as wide and three times as long as the prothorax ; sides subparallel and feebly arcuate in basal two-thirds ; striae moderately strongly punctured. Fe- mora unarmed ; hind tibiae not appreciably curved in the cf ; claws simple. Length, 1.5-1.75 mm. ; width, .6-. 65 mm. Albuquerque, New Mexico (type cf); Las Vegas, New Mexico ; Williams and Walnut, Arizona ; the latter from Prof. Wickham. In the 9 the beak is considerably longer and more slender, the antennae inserted scarcely perceptibly behind the middle. The last ventral is about one-half longer than the preceding in the d^, scarcely longer than the preceding in the 9, in which it bears a median rounded impression. This species is strikingly similar to A. tenuis described above, and with it is often held in collections as wa;^/«, which name, indeed, it has borne in my collection for many years. The simple claws of course will at once separate it from both tennis and nanus. In temiis the antennae are inserted distinctly beyond the middle of the beak in the cf. E. nanulus is a close relative of the present species and from the same type locality. It differs in its sparser vestiture, the scales less broadly rounded, the relatively greater width of the elytra as compared with the prothorax, and the black or piceous legs and antennae. E. canoides n. sp. — Very like the preceding but larger, elytra at base nearly one-third wider than the prothorax, abdomen clothed medially with sparser narrower scales, the latter becoming hair-like on the last segment, which in the c? is nearly as long as the two preced- ing. Front thighs with a small spiniform tooth ; hind tibiae distinctly though not very strongly curved in the cf. Length, 2-2.15 mm.; vi^idth, .8-. 85 mm. Type. — cf ; from El Paso, Texas; two c?'s, two 9 's. E. niodicus n. sp. — Piceous, legs and beak rufotestaceous, an- tennae pale at base, gradually infuscate outwardly ; vestiture whitish throughout, consisting of moderately broadly oval lanceolate scales on the prothorax, oblong and truncate on the elytra, moderately dense but not often overlapping except more or less so in three thoracic vittae and in the condensed lines occupying the greater part of the H. C. FALL. 61 fourth and the basal half of the sixth elytral intervals ; scales broad beneath on the sterna, sparse, narrow and hair-like on the abdomen. Beak about one-half longer than the prothorax, rather finely but closely subrugose punctate and dull almost throughout, the tip ieebly shining. Head with non-contiguous elongate scales, frontal fovea indistinct, eyes separated by a little less than the basal width of the beak. Antennal funicle 7-jointed, first joint nearly as long as the next three, second less than twice as long as wide and not much longer than the third ; club fully as long as the five preceding joints. Prothorax moderately transverse, sides gradually not strongly con- vergent from the base, apical constriction very broad and feeble ; punctuation moderately coarse and close. Elytra about one-fourth wider than the prothorax, humeral angles narrowly rounded, sides parallel in basal half, striae feebly impressed, moderately punctate, intervals nearly fiat. Front thighs with a small acute tooth, middle and hind thighs not evidently toothed ; front tibiae incurved at apex, middle and hind tibiae nearly straight. Last ventral segment but slightly longer than the preceding. Length, 2 mm. ; width, .9 mm. Type. — From Santa Rita Mountains, Arizona. This species must be near airvipes, but the latter accord- ing to description has an ill-defined subdenuded patch at sides of elytra posteriorly, and the middle thighs obviously toothed. The hind tibiae are also said to be curved in both sexes of curvipes, but this seems very unlikly, and I strongly suspect that Dietz's specimens are all cf 's. Since writing the above I have seen the Dietz Collection and find there two examples of airvipes. The first, bearing the label and best fitting his description, and hence to be re- garded as the type, is from Nevada. The subdenuded area called for by the description is scarcely evident, and I could not make out the tooth of the middle thighs ; if present it must be very small. There is no reliable indication of sex in this specimen except the rather strongly curved hind tibiae, which in all other instances known is characteristic of the cf; nevertheless I believe this specimen to be Dietz's supposed 9 . The second example is an undoubted c? from New Mexico. It is more densely scaly, the antennae inserted dis- tinctly beyond the middle of the beak, form a little narrower, sides of prothorax more incurved at base, hind tibiae barely as strongly curved. In the Nevada type the antennal inser- tion is less apical, being at about the middle of the beak, TRANS. AM. ENT. SOC. , XXXIX. fi^ COLEOPTERA RHYNCHOPHORA. haps is why it was called a 9 by Dietz. I feel it that both of Dietz's specimens are cf's, and resent distinct species. The exact relation of .,.^...<,<^o Lu tiuvipes cannot be stated until both sexes of each form are known ; for the present modicus may be separated by its somewhat denser vestiture, especially on the fourth and sixth elytral intervals, the lack of any trace of a lateral subdenuded area, and the pale legs. It is not unlikely that Dietz's New Mexico cf is identical with my Epimechus nanu- lus described from the 9 and also from New Mexico. The very small size of na7iuhcs make this a little doubtful, how- ever, and here again we must wait till both sexes are taken together. E. inobilis n. sp. — Form rather short oblong oval, piceous, legs reddish, body densely clothed above with broadly oval or rounded largely overlapping scales, ashy-gray varied more or less with pale brown to fuscous. The darker scales form two more or less obvious pronotal vittae alternating with pale. The elytra may be almost en- tirely cinereous, the darker scales few, or so pale as to be inconspicu- ous, or the latter may predominate, leaving the suture, a median vittae on the fourth interspace and the basal part of the sixth interspace pale. The antennal funicle is 6-jointed, the second joint a little longer than the third but scarcely as long as the two following, barely twice as long as wide in the cf, but fully so in the 9 . Antennae inserted near the middle of the beak in the c?, slightly behind the middle in the 9 , the beak rather strongly curved, subcarinate in basal half. Prothorax one-fourth wider than long, sides moderately arcuate and convergent, apical constriction rather feeble, sculpture concealed by the vestiture. Elytra one-third longer than wide, sides parallel and nearly straight in basal three-fifths. Body beneath squamose, the scales of the ven- tral segments narrower and less dense. Fifth ventral segment a little longer than the fourth in the c? , scarcely so in the 9 . Legs rather stout, femora apparently completely unarmed : hind tarsi straight in both sexes. Length 2-2.25 mm. Southern California — Pomona (type d^ ) , Claremont, Azusa, San Diego. This species was first taken by me some twenty years ago and was at that time identified for me by Ulke or Horn as nevadicus, under which name I sent it out to numerous cor- respondents. A comparison which I have just made with the type of nevadicus shows it to be quite distinct, however, H. C. FALL. 63 by its notably stouter form. The lobes of the third tarsal joint are not as narrow as in yievadiais, and there is no ap- preciable tooth on the front thighs. The following table though not quite as satisfactory in every respect as I could wish, will help to identify the spe- cies of Epimechus thus far described. Table of Epimechus.

SOC, XXXIX. 64 COLEOPTERA RHYNCHOPHORA. Alycodes dubiiis Dietz. Ellesclius angustatus Dietz. As suspected by Casey, both these species belong to the genus Dorytomus. The former is very like and probably identical with brevicollis Lee, the latter is close to sgiiafuosiis Lee, and quite likely no more than a slight variety of that species. It seems to be a bit narrower than the type of sgtia- mosus, the elytral scales more uniform in width, the tessella- tion more feebly marked. Orcliestes armatulus Dietz. An examination of the type shows it to be a specimen of Psomus PolitusC^y., in which the elytra are transversely frac- tured each side behind the humeri — presumably by being grasped too tightly with forceps — the posterior edge of the fracture being more prominent and simulating an anteriorly projecting spine when viewed from above. The error is a remarkable and scarcely excusable one, since one would expect the most careful verification of appearances by the describer before announcing so singular and unexpected a character. The true state of affairs is not very difficult to make out on close inspection, and such inspection should have revealed the very approximate eyes, pectoral channel and other features quite impossible in an Orchestes. ORCHESTES 111. O. illiiioisensis n. sp. — Black, lustre dull ; pubescence whitish, rather long and conspicuous, recumbent, dense on the scutellum. Antennal funicle 7-jointed, in great part rufotestaceous, club piceous, Prothorax one-half as wide as the elytra, sides parallel in basal two- fifths, hind angles nearly rectangular, punctuation dense but only moderately coarse. Elytra elongate oval, scarcely impressed, striae distinctly impressed, intervals somewhat rugose. Length, 2.35 mm. ; width, 1.2 mm. Type. — From Algonquin, Illinois (Nason). A second specimen also from northern Illinois in Mr. Blanchard's col- lection. By Dietz's table this falls neoiX parvicollis, which is a some- what stouter species with more evidently impressed elytra and shorter blackish pubescence. The resemblance to pa Hi- H. C. FALL. 65 cornis is closer, but this has a 6-jointed funicle, the form is slightly more slender, the prothorax relatively smaller, the pubescence less conspicuous and the elytral striae less im- pressed. CONOTRACHELUS Sch. C. atokamis n. sp. — Form and size oi pusillus, brown or piceous, densely clothed with subcontiguous oblong oval ochreous and white scales and sparse short recurved bristles, which are difficult to detect except in profile. The ochreous scales predominate and determine the general color ; the white ones are aggregated in small spots on either side of the middle and at the sides of the prothorax, at the base of the third elytral interspace and at the anterior and posterior thirds of the elytral disk, the latter also with scattered small blackish areas which are due as much to exposure of the derm as to the color of the scales. Beak rather stout, moderately curved, but slightly longer than the prothorax in the c?, a little longer in the 9, sulcate and clothed with filiform scales behind the insertion of the antennae, which in the d^ is at the apical third, and in the 9 at about the middle ; beyond the an- tennae rather coarsely punctate in the c?, smoother and more finely punctate in the 9 . Prothorax wider than long, sides parallel and feebly arcuate in basal half, narrowed in front with moderate apical constriction ; surface neither densely nor very coarsely punctate, en- tirely without sulci or costae. Elytra two and two-thirds times as long and a little less than twice as wide as the prothorax, one-third longer than wide, humeri nearly rectangular, narrowly rounded, sides straight and parallel for about half their length, then gradually narrowed and parabolically rounded at apex ; strial punctures rather fine, the inter- vals wider than the striae, feebly convex, the alternate ones not appre- ciably more prominent except on the declivity. Beneath sparsely clothed with squamiform hairs or narrow scales, punctuation not very coarse, that of the ventral segments uniform and rather close. Meso- sternum not protuberant ; thighs feebly annulated and armed with a small tooth; claws with an acute basal tooth. Length, 2.8 mm. ; width, 1.5 mm. Type. — c?" ; from Atoka, Indian Territory. Three examples collected by Prof. Wickham. One of our smallest species, resembling in a general way pusillus, but differing by the completely non-costate elytral intervals, non-protuberant mesosternum and generally finer punctuation. Pusilhis seems to be very rare in collections. Two specimens, agreeing in all essentials with the type, were taken by the writer many years ago near Providence, Rhode Island. It was described from Florida. TRANS. AM. ENT. SOC. , XXXIX. (9) 66 COLEOPTERA RHYNCHOPHORA. C. floridanus n. sp.— Form oblong oval, nearly as in pusillus, piceous, tibiae and tarsi rufopiceous, closely though not very densely, somewhat unevenly clothed with narrow scales and squamiform hairs, mostly ochreous in color but sparsely intermixed with Vv^hite, the latter condensed in a short transverse fascia at the summit of the elytral declivity, and in a few very small spots on the costae. One example shows four very small white spots, each consisting of from four to six squamules, arranged in a median transverse series on the prothorax, these being nearly obsolete in a second example. Beak moderately stout, about one-third longer than the prothorax in the cf , about one- half longer than the prothorax in the 9 , shining and sparsely finely punctate apically. more coarsely punctate and substriate basally, a dis- tinct punctiform fovea between the eyes. Antennae inserted barely visibly in advance of the middle (c?) or slightly behind the middle (9 ); second and third funicular joints equal and each as long as the third and fourth united, the third slightly longer than the fourth. Prothorax not much wider than long, sides parallel and feebly arcuate in more than basal half, rather suddenly narrowed and constricted in front, surface moderately coarsely and densely punctate, the median line narrowly rather feebly cariniform, becoming obsolete basally. Elytra fully one-half wider and two and one-half times as long as the prothorax, sides parallel in basal half, then gradually parabolically rounded at apex ; alternate intervals 3-5-7-9 distinctly though not very strongly costate, strial punctures moderately coarse basally, much finer toward the apex. Mesosternum protuberant, ventral segments rather finely punctate, the third and fourth very sparsely and finely so, the last segment more closely punctured, broadly convex in the d^, nearly flat in the 9 . Thighs with a moderate tooth ; claws with a small and broad basal tooth. Length, 4.4-5 mm. ; width, 2.2-2.4 mm. Type. — From Miami, Florida. One pair. In the table given by LeConte in the " Rhynchophora," floridanus must be placed neax posticatiis, from which it differs by its more conspicuous and coarser vestiture, more oblong form, less developed pronotal and elytral costae, and much sparser and finer ventral punctuation. In the 9 type the posterior elytral fascia is ill-developed. C. iieoinexic.aiius n. sp.— Rather closely similar in form sculpture and general facies to elegans, but much larger, vestiture rather coarse and denser, prevailing tint ochreous-brown, with the thoracic lines, posterior elytral band and femoral rings whitish. The elytral band is biarcuate anteriorly, most advanced on the second costa, and most developed posteriorly from the suture to the first costa, narrowed to the lateral margin, which it attains at a point opposite the first ven- H. C. FALL. 67 tral suture. There is a feeble incomplete pronotal carina. The beak is finely densely punctate, striate laterally toward the base, though not as conspicuously so as in elegans, median line cariniform basally ; antennae inserted at middle. Ventral segments densely uniformly punctate, the first with a median longitudinal impression, the fifth rather broadly not deeply foveate at middle ; all else nearly as in ele- gans. Length, 6.75 mm. ; width, 3.15 mm. Type. — From New Mexico. A single example of doubtful sex. Though obviously re- lated to elegans it is quite different from anything else in our fauna, and I have not been able to identify it with any Mexi- can species. ACALLODES Lee. A. lysiiiiacliiae n. sp. — Closely allied to ventricosus and saltoides and best described by comparison with these two species. In many respects it occupies an intermediate position. The prothorax is more nearly like ventricosus , but the sides are a little more oblique basally, the elytra are shorter and more ventricose than in ventricosus, not per- ceptibly longer than wide, humeri narrow and obtuse but distinct ; elytral bands of narrow whitish scales, made up of elongate spots on the intervals, the spots inclining to be better developed but not appre- ciably more advanced on alternate intervals, as they are quite con- spicuously in ventricosus. The space between the transverse bands is a trifle darker owing to the presence of fine blackish feebly clavate in- clined hairs which are also present elsewhere on the intervals and are best observed in profile. The elytral striae are wider than in ventri- cosus, but less so than in saltoides. Middle and hind tibiae strongly unguiculate in the cf ; thighs scarcely toothed, In ventricosus the elytra are quite distinctly longer then wide, in saltoides wider than long according to Dietz, but in the single example before the length and width are almost exactly equal. The humeri are a little better developed in ventricosus, entirely wanting in saltoides, in which the thorax is much shorter and more rapidly narrowed from the base, the elytral striae deeper and wider, and the transverse bands ill-defined. The sutural white spot at base of elytra is present in all, but most distinct in ventricosus. In many specimens of lysimachiae the elytra are red- dish-brown, in others dark brown, perhaps indicating different stages of maturity. Length, 2.5-3 mm. ; width, 1.7-2 mm. Type. — c5^; from Tyngsboro, Massachusetts. Taken abundantly in September on Lysimachia stricta by Mr. Frederick Blanchard, to whom I am indebted for a good series of specimens. TRA.NS. AM. ENT. SOC. , XXXIX. 68 COLEOPTERA RHYNCHOPHORA. AULEUTES Dietz. A. luarioiiis n. sp. — Ve-y broadly oval, pitchy brown, thinly clothed with very short concolorous hairs, with short intermixed white hairs which tend to aggregate in small scattered spots on the elytra. Beak stout, as long as the prothorax, coarsely densely punctate in feeble longitudinal sulci with raised lines between ; front flat, densely punctate, orbital margins elevated. Antennal funicle 6-jointed, first three joints subequal in length, the first stouter, third just visibly shorter than the second and rather longer than the fourth and fifth together. Prothorax strongly transverse, sides parallel in basal two- fifths, apical constriction rather narrow and deep, front margin obtusely angulate each side of a small shallow median emargination, dorsal channel distinct, lateral tubercles small, acute, punctuation dense, moderately coarse. Scutellura very small but distinct, elongate, glab- rous. Elytra fully as wide as long, three-fourths wider than the pro- thorax, humeri rather prominently rounded, sides thence gradually arcuately convergent to apex ; strial punctures rather coarse, intervals alternately wider and strongly elevated, the wider ones especially rough- ened with small acute granules. Beneath coarsely punctured, meta- sternum obviously but not deeply emarginate for the tip of the beak. Legs rather slender, tarsi paler, tibiae with outer margins strongly curved near the knee but not angulate : claws with a very short acute basal tooth. Length, 2\ mm. ; width, 1| mm. Described from a single specimen (type) taken at Marion, Massachusetts, by Mr. Frederick Blanchard. The facies is almost precisely that of Craponius inaegualis, the generic characters are, however, those of Aiileiites . The 6-jointed funicle, with very long and subequal second and third joints, and the strongly elevated alternate elytral intervals, strongly characterize this species. Only one other species of the genus — the tuberadatus of Arizona — has a 6-jointed funicle, and in it the second and third funicular joints are shorter than the first, and the elytral intervals nearly equal in width and convexity. BARIS Germ. B. texamis n. sp. — Elongate oval, black, legs rufopiceous, upper surface somewhat dull from the density of the sculpture, the inter- spaces of the pronotum are, however, polished and of the elytra shin- ing and feebly wrinkled ; setae fine, short, recurved, distinct but not very conspicuous. Head sparsely punctate, transverse impression very broadly angulate in profile. Beak coarsely and densely punctate throughout, three-fourths as long as the prothorax, nearly evenly arcu- ate. Antennal funicle rather short and stout, basal joint less than twice as long as wide, seventh joint three-fourths as wide as the club H. C. FALL. 69 Prothorax one-tenth wider than long, sides very feebly arcuate and moderately convergent to apical fifth, then strongly arcuately nar- rowed to apex, which is about two-fifths as wide as the base; disk coarsely densely punctate, the punctures nearly in mutual contact throughout, median smooth line very narrow and not entire. Scutel- lum transverse, impressed. Elytra nearly three-fifths longer, and at the humeri one-fifth wider than the prothorax, just perceptibly nar- rowed from the humeri to apical third ; striae rather coarse, feebly in- distinctly punctate basally, intervals about one-half wider than the striae, interstitial punctures very coarse and close set, nearly as wide as the intervals, confused on the third and somewhat so for a short distance on several of the following intervals. Beneath coarsely closely punctate; prosternum nearly flat, separating the coxae by rather more than one-fourth their own diameter. Length, 3.9 mm. ; width, 1.85 mm. Type. — From Fedor, Texas. This species is probably nearest hispidula Csy, but differs in numerous details from the description of that species, which is said to be brown, pronotal punctures separated by their own diameters, the elytral striae rather strongly punc- tured, the interspaces but slightly wider than the striae, each with a single series of punctures. B. apricoides n. sp. — Oblong oval, rather strongly convex, dark piceous-brown, moderately shining, surface between the punctures mi- nutely alutaceous, setae small but distinct, recumbent. Head minutely sparsely punctulate, transverse impression strong, broadly angulate in profile. Beak very^ short, thick, strongly arcuate in anterior outline, scarcely two-thirds as long as the prothorax, rather strongly and closely but not coarsely punctate. Antennae short, first funicular joint very little longer than wide, following joints strongly transverse, club robust oval, scarcely longer than the four preceding joints, the basal joint polished, nearly glabrous and constituting about one-half its mass. Prothorax scarcely one-sixth wider than long, sides broadly arcuate and distinctly convergent from the base to the anterior fifth, thence more strongly rounded to apex, which is about two-fifths as wide as the base ; disc coarsely and densely punctate, the punctures separated by much less than half their own diameters as a rule, median impunc- tate line narrow and incomplete. Scutellura small, subquadrate, not or feebly impressed. Elytra slightly wider and not quite three- fourths longer than the prothorax, a little more than one-third longer than wide, sides nearly parallel, striae moderately coarse, intervals a little less than twice as wide as the striae, the second and third wider, each with a single series of coarse close set punctures which are con- fused only at the base of the second and third. Punctuation beneath TRANS. AM. ENT. SCO. , XXXIX. 70 COLEOPTERA RHYNCHOPHORA. moderately coarse and close ; prosternum broadly longitudinally im- pressed or concave at middle, separating the coxae by about two-thirds their own width. Length, 3.6 mm. ; width, 1.65 mm. The type is a d^ from Cloudcroft, New Mexico, collected by Mr. Knaus. With it I have placed a series from the Chiricahua Mountains of Arizona (Clemence) and others from Nogales, Arizona (Nunenmacher). One c^ from the Chiricahuas agrees almost perfectly with the type; the other examples are slightly stouter with the sides of the thorax a little less convergent though obviously so, and there is a more obvious confusion of the interstitial punctures of the second and third elytral intervals. This species is plainly close to aprica Csy, which is said, however, to be polished, prothorax one-third wider than long, with sides almost parallel and straight in basal two-thirds, and the elytral inter- spaces but slightly wider than the striae. jB. tectiisn. sp. — Oblong oval, convex, black throughout, polished ; setae long, white, subrecumbent and very conspicuous. Head finely sparsely punctate, transverse impression broadly angulate in profile. Beak stout, arcuate, not quite three-fourths as long as the prothorax, quite densely punctate. First funicular joint nearly twice as long as wide, second nearly as long as wide, following joints increasingly trans- verse ; club oval, fully as long as the five preceding joints, polished and glabrous in about basal half. Prothorax not quite one-fifth wider than long, sides feebly arcuate, nearly parallel in basal half or two- thirds, apex scarcely two-fifths the basal width ; disk coarsely densely punctate, punctures separated by one-third to one-half their own diameters, median smooth line narrow and incomplete. Scutellum small, subquadrate. Elytra a little wider and three-fifths longer than the prothorax, one-fifth longer than wide, sides parallel, striae moder- ate, intervals about two-thirds wider than the striae, second and third widest, interstitial punctures rather coarse, close set, and more or less irregular or confused on nearly all the intervals, except toward the apex. Beneath moderately coarsely closely punctate ; prosternum feebly concave at middle, separating the coxae by slightly more than half their own diameters. Length, 3.4 mm. ; width, 1.65 mm. Type. — From Chiricahua Mountains, Arizona. Described from a single example, apparently a male, col- lected and given me by Mr. V. L. Clemence. By Casey's table this species would come between vesper- tina and oblongula. Vespertina differs in its piceous-brown color, the setae are said to be semi-erect and arranged with- H. C. FALL. 71 out order on the elytra, the prothorax is one-half wider than long-, with the apex fully one-half as wide as the base, the elytra are relatively a little longer, and there are some other differences in detail. Oblongida differs notably in its dull strongly alutaceous lustre, the beak is shorter, the antennal club smaller, and there are many other differences obvious when descriptions are compared. In tectiis the elytral setae are subequal in length to the width of the interspaces. B. pruiiliuiis n. sp.— Oblong oval, black, moderately shining, with a pruinose aspect because of the numerous white setae, which are long, coarse, blunt at tip, and recumbent. Beak very short, stout, evenly arcuate, scarcely half as long as the prothorax, rather finely and not very closely punctate. Antennae nearly as in the preceding species, except that the club is here distinctly compressed. Prothorax densely punctate with a narrow median smooth line which is variable in distinctness ; sides very broadly arcuate and feebly convergent from base to near the apex, thence more strongly but not very abruptly rounded, the apex about one-third as wide as the base. Elytra barely perceptibly wider than the prothorax, slightly gradually narrowed be- hind, intervals from two to three times as wide as the striae, the second and third widest, interstitial punctures confused on all the intervals for the greater part of their length. Prosternum feebly longitudinally con- cave at middle, separating the coxae by two-thirds to three-fourths their own diameters. Other characters nearly as in the preceding spe- cies. Length, 3.6-4 mm. ; width, 1.8-1 95 mm. Type. — From El Paso, Texas. This and the preceding species are rather closely allied in a general way, and especially by the long conspicuous setae ; the present one, however, is larger and more oval in outline, with shorter beak and more compressed antennal club. B, nevadicus n. sp. — Narrowly oblong oval, black, polished, legs rufous; setae very fine, short and inconspicuous. Head finely sparsely punctate, transverse impression distinct, broadly angulate in profile. Beak stout, strongly arcuate, nearly four-fifths as long as the prothorax, rather strongly and closely punctate. First funicular joint fully two- thirds longer than wide, second nearly as long as wide, club rather small, scarcely longer than the four preceding joints. Prothorax one- fourth wider than long, sides very broadly arcuate and feebly convergent to apical fifth, thence strongly rounded to apex, which is one-half as wide as the base ; surface rather coarsely and densely punctate, with nar- row distinct and nearly entire smooth median line. Scutellum small, unimpressed. Elytra a little wider than and not quite twice as long as the prothorax, about one-third longer than wide; striae fine, deep, TRANS. AM. ENT. SOC. , XXXIX. 72 COLEOPTERA RHYNCHOPHORA. scarcely visibly punctate, intervals a little more than twice as wide as the striae, second and third a little wider and fully three times as wide as the striae ; interstitial punctures fine and not very close on the inner intervals, on the outer intervals coarser and closer and about one-half as wide as the intervals. Beneath coarsely closely punctate, the abdo- men more sparsely so, especially at the middle ; prosternum nearly flat, separating the coxae by slightly more than half their own diameters. Legs moderately punctate. Length, 3.75 mm. ; width, 1.7 mm. Type. — From Ormsby County, Nevada (Baker). The type is a male with abdomen at base strongly im- pressed. The prothorax being more than half as long as the elytra would lead the student to place this species under "16" in Casey's table; but the other characters are more in harmony with the following species and lead us to " 22 " in the neighborhood of sparsa. The latter is smaller (2.8-3 mm.), dark rufopiceous in color, with distinctly sparser punc- tuation both of the pronotum and elytra. PYCNOBARIS Csy. P. iiigTOStriatiis n. sp. — Oblong ovate, black, shining, clothed rather densely with robust parallel truncate or subtruncate recumbent white scales, which are on the average from three to four times as long as wide. Head minutely sparsely punctate. Beak robust, three-fourths as long as the prothorax, its anterior outline strongly evenly arcuate, posterior outline straight for the greater part of its length when viewed in profile ; punctuation close, forming rugae at sides, squamose laterally toward the base. Antennae nearly as in pruinosa. Prothorax very nearly as long as wide, sides convergent and nearly straight from base to apical fifth, then strongly rounded to the well marked apical con- striction ; surface densely coarsely punctate, the punctures about one- third as wide as the scutellum and nearly in mutual contact. Elytra about one-third longer than wide, three-fifths longer and at the humeri about one-sixth wider than the prothorax, sides very feebly conver- gent from the humeri, discal striae coarse and deep, feebly punctate, glabrous ; intervals but little wider than the striae, irregularly rather coarsely punctate and densely squamose, the white vestiture contrast- ing strongly with the black striae. Beneath densely punctured and squamose. Prosternum flat, nearly as wide between the coxae as the coxal width ; transverse impressed line or sulcus deep, midway between the coxae and the front margin. Length, 3.6 mm. ; width, 1.75 mm. Type, — From Palm Springs, California (Fenyes). Readily distinguished from our two previously described species by the coarser glabrous striae and narrow intervals of the elytra. The vestiture is much denser than in pruinosa. CONTENTS.

Clypeus smooth, but very delicately punctate. Head dark. Dorsum of thorax yellow in front, but black between wings and zvith only a slight admixture of yellow hairs on the scutellum. Pleura black. Dorsum of abdomen mostly black, except the third a^id fourth segments clothed with yellow pile. Legs dark. Queen. Head. — With little or no light or yellow pile. Malar space longer than its width at apex, nearly one-third as long as the eye. Clypeus very smooth and shining, with very delicate punctures. Thorax. — Dorsum in front of wing bases covered with yellow pile, between the wing bases black, and on the scutellum black except for a noticeable, though slight, admixture of yellow hairs. Mesopleura entirely black from the level of the bases of the wings to the bases of the legs. Metapleura and sides of median segment entirely black.

Worker and male. — Unknown. Dimensions. — Length of queen about 19 mm. The queen is here redescribed from two specimens in the collection of the American Entomological Society. Habitat. — Mexico (Oaxaca). I think this species belongs to the Pratorum group and has its closest relative in vosnesenskii. It resembles quite closely, in general appearance, the queen of califoryiicus, but it may be readily separated from that species by its much smoother clypeus and by its more chunky form as well as by certain differences in coloration. HENRY J. FRANKLIN. 85 Boinl)us (Bonibus) laticiiictiis new species. Types. — Described from seven worker cotypes and one male type, all collected by C. H. T. Townsend in Meadow Valley, head of Rio Piedras Verdes (six miles south of Colo- nia Garcia), Sierra Madre of western Chihuahua, Mexico — about 7,000 feet altitude. Of these specimens, one worker is deposited in the collection of the Massachusetts Agricul- tural College and the remainder in the collection of the United States National Museum. Much like huntii, but zvith a >uuch rvider black interalar band. Quee7i. — Unknown. Worker.

Venter with the apical margins of most of the segments heavily fringed with pale yellow hairs. Genitalia. — About like those of huntii. JVings .—Only very slightly infuscate ; the fore pair clear trans- parent, except in the region beyond the veins, this region being slightly darker than the remaining portion. Legs.—Coxse, trochanters and femora all clothed very largely with yellow pile, the femora, however, with dark hair on their upper sides and around their distal ends.

Types. — Smith's formosus is probably still extant in the British Museum collection, and a comparison of some pulcher queens with the forniosiis type would probably settle once for all the old question as to whether there is an East Indian species closely resembling the American one in coloration. Smith's description of formosus deals mostly with coloration and, were coloration alone sufficient to determine a Bombus species, I should say that, without a possible doubt, fonnosus was pulcher. When I think, however, of such cases as the European confusus, which so closely resembles in coloration both brachycephahis and dolichocephalus of Central America, I hesitate to consider two forms the same, even when they are exactly alike in coloration, unless I know their structure is also the same. There are authentic specimens of Cresson's pulcher in the collection of the American Entomological Society. The type specimens of the worker and male castes are in the collection of the k. k. Hofmuseum at Vienna. Pile of medium length and rather fine. J^/f alar space of females short, of males medimn. Head dark. Thorax dark on dorsum, but yellow 07i pleura.

Genitalia. — Outer and inner spathae much like those of B. ephippia- tus. Claspers (fig. 154 and fig. 194) a good deal like those of ephip- piatus, but with the apices of the branches, as seen dorsally, rather more quadrate and somewhat narrower in proportion to their pre- apical portions, and with the squamae having their inner margins evenly incurved from base to apex and their bases considerably wider than the apices of the branches.

They grade com- pletely (the gradations are before me) into the typical forms above described. Color Variant 7.— Queen like the typical queen, but with the ferru- ginous-red pile on the second and third dorsal abdominal segments largely, though not entirely, replaced with black, the replacement on the second segment consisting of a rather weak admixture of black hairs with the red on the extreme sides of the segment, and on the third segment consisting of a black area on the extreme sides, this area narrowing and extending half-way to the middle line along the front margin of the segment. One specimen from Olas de Moka, Depart- ment Solola, Guatemala — 3,000 feet altitude. Color Variant 2.— Worker like the queen of Color Variant 1, but with the black predominant on the sides of the second abdominal seg- ment, there being only a moderately strong admixture of ferruginous- red hairs with the black, and with the outer two-thirds of each red patch on segment three completely replaced by black.

Male Color Variaftt 4. — Like typical male, but with the fourth dorsal abdominal segment covered with ferruginous-red pile, except for a strong admixture of black hairs on its basal middle. One specimen from Ozumba, Mexico — 8,088 feet altitude. Habitat. — We have the following certain records for this species : Mexico (Ixtaceihautl, Popocatepetl — 8,000 feet alti- tude, Ozumba, Jalapa), Guatemala (Olas de Moka — Depart- ment Solola) and Venezuela. Pidcher is a very appropriate name for this species, for it is indeed a handsome one. It has its nearest ally in ephip- piatjis, the only marked structural difference between the two species being the difference in the form of the squamae of the male genitalia.

Friese's type specimens of weisioso. in his private collection. I am inclined to the opinion that the weisi $ was a worker of this species. I have before me a male iveisi, deter- mined by Friese, and this specimen is certainly not of this species. I here describe the true male for the first time from two cotypes of that sex, deposited in the collection of the United States National Museum. Queen. — I have never seen either a queen or a worker of this species. Smith described these castes as follows : "'Female. — Length 8 lines. Black, pubescent ; the head entirely black, with the clypeus very smooth and shining and delicately punctured. The thorax with black pubes- cence above and beneath, that on the sides pale yellow ; the pubes- cence on the legs entirely black ; the wings fusco-hyaline, the nervures black. Abdomen : the three basal segments clothed with pubescence of a pale yellow, somewhat lemon-colored, that on the third segment not quite extending to the lateral margins ; the apical segment thinly sprinkled with ferruginous hairs." " Worker. — Length 5 lines. Colored like the female." Handlirsch described the queen and worker together, from two specimens of each caste as follows : " Thorax as \n pul- cher ; abdomen with the first and second segments entirely yellow haired, the third segment yellow in the middle ; fox- colored or brown pile absent ; the sixth segment is pale red- dish haired." Friese's description of the worker is as follows : " Black, black-haired ; like B. ephippiatus var. lateralis, but larger ; segments 1-3 yellow-, 4-5 black-, 6 red-haired; with longer cheeks. Length, 15 mm. ; width of thorax, 7i mm." Male. Head. — Face with a mixture of dark and pale yellow hairs ; occiput with dark brown or black pile; sides of head, beneath and behind the eyes, with considerable pale yellow pile (most of this light pile is well under the head, the sides immediately behind the eyes being mostly dark). Malar space apparently somewhat longer than its width at apex, about one-fourth as long as eye. Clypeus shining, finely punctate toward the side and upper margins, but sparsely and delicately punctate over a considerable portion of the disc. Third and fourth antennal segments subequal in length, the fifth nearly as long as HENRY J. FRANKLIN. 97 both together; most of the segments of the flagellum appearing sHghtly arcuate when viewed laterally (the first two segments and the apical one are not at all arcuate). Thorax. — Dorsum clothed with dark brown or black pile ; the front part with a noticeable admixture of pale yellow hairs ; the very center of the disc naked, smooth and shining. Mesopleura covered with pale yellow pile from the level of the bases of the wings to the bases of the legs. Metapleura mostly clothed with pale yellow pile. Sides of me- dian segment also with considerable pale yellow hair. Abdomen. — Dorsum : segments one and two entirely covered with yellow pile ; segment three either entirely clothed with yellow pile or with the greater part yellow and the extreme sides more or less dark ; segment four covered with black pile ; segment five mostly black, but with its very apical margin bearing pale ferruginous pile ; segments six and seven with pale ferruginous pile. Venter dark, but most of the segments with long apical fringes of very pale yellow hairs. Genitalia. — Claspers (fig. 183 and fig. 193) long and appearing moderately powerful ; branches pointed at the apex, as viewed dorsally, with the very points rounded, these apices being bent strongly mesad ; the squamae weakly bilobed, the inner lobe being distinctly larger and more prominent than the outer one, and extending mesad far beyond the inner margin of the volsella (this inner lobe seems to take the form of a fiat plate or scale more than is commonly the case with Bonibus males), the outer lobe short and tending to be pointed, but with the ver}^ apex rather broadly rounded ; volsellae very long and extending considerably beyond the tips of both the sagittae and the squamae, their apices blunt and quadrate and their outer margins evenly out- curved, hairs, except on the basal portion of their inner sides, being unusually wanting. Sagittae with shafts long and bent outward strongly in the middle, with a noticeable projection on the middle of the lower side of each ; their heads reaching as far posteriorly as the apices of the squamae, being somewhat foliaceous and recurved at the tip (this tip being rounded) and without noticeable spines, teeth or points. Uncus moderately broad behind, but tapering to a narrow recurved tip. Wings. — Very light, but slightly infuscate. Legs. — Coxae mostly dark, the hind pair with a few yellowish hairs ; fore and middle trochanters with a considerable amount of very pale yellow pile, the hind pair with only a very little light hair ; the basal halves of the front, and sometimes also of the middle, femora with much pale yellowish hair on their lower sides, the remaining portions all being dark ; the hind femora dark, sometimes with a few light hairs on the lower sides of their basal portions ; tibiae dark, the outer faces of the hind pair slightly convex and sparsely hairy and their hind fringes moderately long ; hind metatarsi oblong, slightly concaved on their TRANS. AM. ENT. SOC, XXXIX. (13) 98 AMERICAN HYMENOPTERA. outer sides, of nearly equal width throughout their length, without long hind fringes. Dimensions. — Length : queen, about 17 mm. ; worker, about 11 mm. ; male, 12 mm. to 13 mm. Spread of wings : male, 26 mm. to 28 mm. Variation. — The principal variation in this species is in the coloration of the third dorsal abdominal segment. If it seems desirable to give names to distinguish the form in which this segment is entirely yellow from the one in which its extreme sides are dark, possibly the name zueisi must go with the former, while the name viontezumce indicates the latter, variation. Perhaps a new name should be given to the first form. Habitat. — Our certain records for this species are : Mexico (Oajaca and Tlalpam) and Costa Rica (San Carlos). This species has its nearest relative in B. nigrodorsalis. It may be distinguished from that species by its having the dor- sum of the thorax dark, without the yellow band across the front part and without the yellow fringe on the hind margin of the scutellum. It may be at once separated from pulcher, ephippiatus and wihnattce by the ferruginous hair on the apex of its abdomen and probably also by its somewhat longer malar space. I consider montezumce and nigrodorsalis the most primitive of all the New World species of Bombus. Boiubus (Bombus) iiigTOClorsalis Franklin. Bombus nigrodorsalis Franklin, Ent. News, XVIII, 1907, p. 90. " " var. laticollis Franklin, Ent. News, 1907, p. 91. Types. — Typical nigrodorsalis was originally described from one queen and one worker. These specimens together with five queens and one worker (paratypes) are in the collection of the United States National Museum. I do not now con- sider the form laticollis to be a good subspecies, but rather look upon it as a color variant. The specimen, from which this variant was described, was a queen. It is also in the collection of the United States National Museum. The type of the male, here described for the first time, is in the same collection. All these type specimens were collected by C. H. T. Townsend in Meadow Valley, head of Rio Piedras HENRY J. FRANKLIN. 99 Verdes (six miles south of Colonia Garcia), Sierra Madre of western Chihuahua, Mexico — about 7,000 feet altitude.

Dorsum of male abdome?i with three basal seg- ments yellow, the apical half bearing black, yellow and ferruginous hairs. Queen. Head. — Face, occiput and ventro-lateral portions all black, except for a slight sprinkling of light hairs, visible with a lens, above the bases of the antennae. Labrum sulcate in the middle and fringed on free edge with ferruginous-yellow hair. Malar space distinctly longer than its width at apex, about one-third as long as eye. Cly- peus rather smooth and shining and very delicately and sparsely punc- tate over the entire surface, except the corners. Third antennal seg- ment somewhat longer than the fifth ; the fifth distinctly longer than the fourth. 7"/%or«.r.— Mesopleura covered with light yellow pile from the tegula- to the bases of the legs, the yellow of the two pleura being connected by a rather narrow band of the same color crossing the dorsum in front, this yellow band not nearly extending back on the middle of the dorsum to even with the tegulae, but its hind border curving forward strongly from them on each side. vScutellum with a mere fringe of yellow hairs behind. Dorsum otherwise entirely covered with black pile, except for a very small bare spot on the center of the disc. Abdomen. — Dorsum: first three segments clothed entirely and rather densely with bright yellow pile ; segment four entirely dark ; segment five mostly clothed with black pile, but with ferruginous hairs on its apical margin ; segment six with ferruginous pile. Venter black to- wards the base, but with the apical fringes of the second, third and fourth segments light yellow ; hair fringing the apical margin of the fifth segment and the entire sixth segment yellow. Hypopygium with- out median carina. Wings. — Somewhat stained with brown. Legs. — Middle and hind coxae usually bearing some yellow hairs, but sometimes entirely black ; femora all dark and bearing no light or yellow pile ; front and middle tibias dark ; hind tibiae sometimes entirely and always mostly black, sometimes with some of the hairs in the hind corbicular fringes tinged with pale ferruginous color. Worker. — Like the queen, except in size, but with corbicular fringes entirely black and the pile of the apical abdominal segment and the apical fringe of the fifth segment much less strongly ferruginous than in the queen. TRANS. AM. ENT. SOC. , XXXIX. 100 AMERICAN HYMENOPTERA. Male. Head. — Face with only cinereous (black and whitish hairs mixed) pile. Occiput entirely dark. Ventro-lateral portions with mostly cinereous or pale pile. Malar space distinctly longer than its width at apex, nearly one-fourth as long as eye. Clypeus mostly naked and moderately punctate, the punctures over the greater part of the disc being for the most part rather delicate. Fifth antennal segment much longer than third and third much longer than fourth. Thorax. — Coloration of pile much like that of queen and worker, but with the yellow pile on the front part of the dorsum reaching back to nearly even with the tegulae all the way across ; metapleura and sides of median segment clothed rather densely with pure pale yellow pile. Abdomen. — Dorsum : segments one, two and three entirely covered with pale yellow pile ; segment four mostly dark, but with apical mar- gin bearing whitish yellow pile and with yellow hairs more or less ad- mixed with the black, except on the very middle portion, the extreme sides having this yellowish admixture very strongly; segment five mostly dark, but with a fringe of whitish hairs on the middle of the apical margin ; segment six dark, but with apical margin bearing fer- ruginous hairs ; segment seven with ferruginous clothing. Venter with mostly whitish-yellow pile. Wings. — Very light, almost clear transparent, only slightly infuscate.

Hind metatarsi with outer faces nearly flat and hind fringes, for most part, short. Dimensions. — Length: queen, about 19 mm.; worker, about 12^ mm. ; male, nearly 14 mm. Variation. — The description of the color variant {laticollis) is as follows : Like typical nigrodorsalis queen, but with band of yellow pile, running across anterior part of dorsum of thorax, much wider and reaching back in the middle to even with the tegulse. Middle and hind trochanters and bases of hind femora beneath bearing considerable yellow pile. Hind fringes of corbiculse strongly ferruginous. This species has its closest relative in montezumce.

Types. — The type of the queen caste, described here for the first time, came from Ecuador and is deposited in the collection of the United States National Museum. Cockerell's worker type came from Antigua, Guatemala. Handlirsch's specimen came from Guatemala. I have not seen Cockerell's type. Pile rather short and fine. Malar space rather short. Head mostly dark. Dorsum of thorax pale yellow, with a black interalar band. Dorsum of abdomen with first segment yellow ; second mostly yellozv, but black on the extreme sides ; third yellow in the middle and black on the sides ; the remainder black. Corbicular fringes dark. Queen. Head. — Face mostly dark, but with a slight sprinkling of pale yellow hairs above the bases of the antennas. Occiput with a strong admixture of pale yellow hairs. Ventro-lateral portions of head mostly dark. Malar space shorter than its width at apex, about one- sixth as long as eye. Clypeus, for most part, delicately and rather sparsely punctate. Third antennal segment longer than the fifth, the fifth longer than the fourth. Thorax. — Dorsum yellow, with a weak and poorly defined black interalar band, the yellow strongly encroaching on the black pile, especially near the bases of the wings. Mesopleura yellow to the bases of the legs. Metapleura mostly clothed with yellow, and sides of me- dian segment with a large amount of yellow pile. Abdomen. — Dorsum : segment one yellow ; segment two about two- thirds clothed with yellow pile, this yellow portion being all in one area on the middle of the segment and extending from the front mar- gin back to the hind one, the sides of this area converging posteriorly, the sides of thesegment being black; segment three black, except for a patch of yellow on the middle third, the sides of this patch converging posteriorly, but not meeting ; segments four, five and six black.

SOC. , XXXIX. 102 AMERICAN HYMENOPTERA. tirely dark and sometimes with yellow strongly predominant above the bases of the antennae, there being all gradations between these two conditions on both face and occiput. Dorsum of thorax as in queen, but with interalar band broad and usually well defined (this band is of varying width in different individuals, reaching a maximum of two- thirds as wide, from front margin to rear margin, as long, from wing base to wing base). Yellow patch on third dorsal abdominal seg- ment sometimes covering not more than one-fifth of the segment and sometimes covering nearly half of it, but usually covering less than one-third, its sides often rapidly diverging (instead of converging) posteriorly. Wings. — Light, transparent, only slightly infuscate. Z.i?^.f.— Mostly dark ; in all but one specimen, lacking the yellow pile present on some of the hind leg segments of the queen. Male. — Unknown. Dimensions . — Length : queen, about 15 mm. ; worker, 11 mm. to 14 mm. Spread of wings: queen, 36 mm. ; worker, 26 mm. to 29 mm. Width of abdomen at second segment : queen, about 1\ mm. ; worker, 5 mm. to 6| mm. Habitat. — Guatemala (Quiche — one worker, Antigua — six workers, Guatemala City — four workers) and Ecuador (one queen and three workers). This species apparently belongs to the Dumoucheli group and probably has its closest allies in montezumcr and ?ngro- dorsalis. Its yellow pile is very pale yellow. The worker caste is here redescribed from four specimens, one of which was collected in Guatemala (Quiche) and the other three in Ecuador. Bouibus (Bombns) emilise D. T.

Type. — At least a part of Sichel's type specimens are in the collection of the k. k. Hofmuseum at Vienna, as is also Dalla Torre's type of corsiais. Smith's bellicosus is, in all probability, thoracicus. The type of bellicosus is in the collec- tion of the British Museum. Malar space rather short. Females with dorsum of thorax varying from light yelloiv to ferruginous, ivith no black interalar band ; pleura dark ; dorsum of abdomen black, zvith the three apical segments ferru- ginous ; legs black. Males with short malar space ; third and fourth antennal segments subequal ; coloration as in females, but with more or less yellow on pleura, abdomen variable atid legs with considerable yellow pile. Queen. Head. — Mostly black, sometimes with a slight sprinkling of yellow hairs among the black on the occiput or about the bases of the antennae. Malar space a trifle shorter than its width at apex, not over one-fifth as long as eye. Clypeus coarsely punctate, but rather sparsely so on the front portion of its disc. Third antennal segment longer than fifth and fifth longer than fourth. Thorax. — Dorsum clothed entirely with pile of a color var>'ing from pale yellow to deep yellow and even to ferruginous-red, with no black interalar band. Pleura black from level of bases of wings to bases of legs. Abdomen. — Dorsum : three basal segments entirely black (some specimens, however, with a considerable sprinkling of yellow pile on the basal middle of the second segment); three apical segments en- tirely covered with ferruginous-red pile. Venter for most part black, but with apical margins of apical segments fringed with yellowish fer- ruginous hairs. Hypopygium without median carina. Wings. — Very dark, with slight violaceous reflections. Legs. — Coxae, trochanters, femora and tibiae, including corbicular fringes, all black. Worker. — Much like queen ; but pile on dorsum of thorax tending to be paler and the ferruginous pile on the apical abdominal segments somewhat lighter, as a rule, than in that caste ; wings somewhat lighter. Male. Head. — Malar space considerably shorter than its width at TRANS. AM. ENT. SOC, XXXIX. 104 AMERICAN HYMENOPTERA. apex. Clypeus coarsely punctate, except for a small smooth area on the disc. Third antennal segment slightly shorter than fourth, the fifth nearly as long as the third and fourth taken together. Thorax. — Coloration much like that of females, but the pleura with a strong sprinkling of yellow hairs intermixed with the dark. Abdomen. — Dorsum : segment one black ; segment two mostly black, but with a strong admixture of yellow hairs on its basal middle ; seg- ment three dark ; segments four to seven inclusive bright yellow (these segments are probably ferruginous in most specimens). Genitalia. — I have not been able to examine these organs, but, as Handlirsch's and Radoszkowski's figures agree fairly well, I will here give Handlirsch's description of them: " Of the genitalia, the spatha (uncus) is broad at the base and strongly narrowed toward the end ; the squama is much broader than long, on the inner side drawn out into a moderately long peak. The sagittee are, toward the end, bent slightly downward and outward and, in the same place, almost cut square off." Wings. — Somewhat lighter than those of the worker. Legs. — Trochanters and femora bearing considerable yellow pile. Hind tibiae strongly convex on their outer sides. Hairs on tibiae and tarsi very short. Dimeftsions.— Length : queen, about 25 mm.; worker, 15 mm. to 17 mm. ; male, 14 mm. Spread of wings: queen, about 46 mm. The species is here redescribed from three queens, nine workers and one male, all in the collection of the Museum of Comparative Zoology at Cambridge. Variation. — It seems evident, from the published descrip- tions, that the dorsum of the abdomen of the male is quite variable in coloration. In the original description, it is de- scribed as follows : " abdominal segments two and three rufo-cinereous." Handlirsch (vide supra) states that the dorsum of the male abdomen has the first three segments "tawny yellow or only the third and fourth black pilose," the apical segments being ferruginous. The following female variation is before me : Worker Color Variant. — Like typical worker, but with only the api- cal portion of the fourth dorsal abdominal segment covered with ferru- ginous pile, its basal portion being entirely black. Friese (vide supra) describes a color variant of the queen as follows : " var. 9 . Thoracic dorsum dark brown instead of yellow haired. — Salta (N. Argentina) — var. fuliginosus.'' Habitat. — We have sure records for this species as fol- HENRY J. FRANKLIN. 105 lows: Uruguay (Montevideo), Argentina (La Plata, Salta, Tandil — very abundant, Juarez, Rosario, Cordoba, Buenos Ayres) and Brazil (Bahia). The Brazilian record ought, perhaps, to be considered doubtful. This species probably has its closest ally in steindachneri. See the discussion, concerning beliicosus, following the de- scription of baeri. Hudson (vide supra) states that this species is common in La Plata. He says that it usually builds its nest in a depres- sion on the surface of the ground under the shelter of a bush and that the nest is dome-shaped and consists of "small sticks, thorns and leaves bitten into extremely minute pieces."

These specimens are in the collection of the k. k. Hofmusuem at Vienna. Pile rather short and of medium texture. Malar space medium. Dorsum of thorax yellow, zvithotit black interalar ba^id ; pleura dark . Abdomen of females dark, except the third dorsal segment yellow. Abdomen of male dark, with third and fourth dorsal segments yellow. Head of females black. Legs black. Hind tibia" of male convex with- out and thickly covered with short hair. Queen. — I have seen one queen, 21 mm. in length and with colora- tion exactly like that of the worker, in the collection of the American Entomological Society. Worker. Head. — With black pile only. Malar space slightly shorter than its width at apex, about one-fifth as long as eye. Clypeus coarsely, but for most part very sparsely, punctate, a large part of the disc ap- pearing mostly smooth.

Each metapleuron with a roore or less noticeable amount of yellow pile at its extreme upper end, just behind and beneath the base of the hind wing, otherwise entirely dark. Sides of median seg- ment with dark pile only. Abdomen. — Dorsum : segments one, four, five and six black ; seg- ment two usually entirely black, but sometimes with a little yellow pile on its basal middle ; segment three clothed with yellow pile. Venter dark. Hypopygium without median carina. Wings .—Ka.ihev dark, often with slight violaceous reflections. Legs. — All dark and with black pile. Male. Head. — Face with a strong admixture of pale yellow (whit- ish) hairs with the black, this pale color being somewhat predominant on the clypeus. Occiput with yellow pile strongly predominant over the black. Sides of head mostly dark. Malar space about as in worker. Clypeus mostly covered with pile. Third antennal segment very short, distinctly shorter than either the fourth or the fifth, about one and one-half times as long as the pedicel. All but the basal and apical segments of the flagellum of the antenna appearing more or less strongly arcuate when viewed laterally. Thorax. — Coloration of pile about like that of worker. Abdomen. — Dorsum entirely dark, except the third and fourth seg- ments clothed with yellow pile. Venter mostly dark. Genitalia. — Handlirsch describes these organs as follows: "The genitalia resemble very much those of Bombus pennsylvanicus and cayennensis , yet are distinctly different from those of both species ; the branch is as slender as in the former species, and the squama and volsella are also entirely as in that species, but the sagittae are as in cayennensis.''^ Wings. — About like those of the worker. Legs. — Coxse and trochanters with some light pile ; femora and tibiee all dark. Outer sides of hind tibiae convex and slightly im- pressed near the apices; for the most part, evenly covered with short hair, with no long fringes. Hind metatarsi with no long fringes. Dim^ensions . — Length : worker, 13 mm. to 16 mm. ; male, about 16 mm. Spread of wings : worker, 33 mm. to 38 mm. ; male, about 35 mm. Width of abdomen at second segment : worker, 61 mm. to 8 mm. ; male, about 7 mm. The specie.s is here redescribed from five workers and one male. It seems to be quite constant in its coloration. Habitat. — Mexico (Cuernavaca and Tacubaya) and Brazil (Ypanema). All the specimens seen by me came from Mexico, the male being from Cuernavaca. This species is evidently closely allied to emilice. All the yellow pile borne by this species is rather deep yellow. HENRY J. FRANKLIN. 107 Boinbus (Boiubus) opifex F. Sra. Bombus opifex Smith, Descr. New Spec. Hym., 1879, p. 133, n. 10, S . " " Ant.

Mesopleuru covered with yellow pile to bases of legs. Abdomen. — Dorsum : first three segments entirely covered with yel- low and the three apical segments with deep ferruginous-red pile. Venter mostly black, but with a little j^ellow pile on the side margins and with the apical margins of the apical segments fringed with yel- lowish-ferruginous hairs. Hypopygium without median carina. Wings. — Considerably infuscate. Legs. — Coxae, trochanters, femora and tibiae black. Corbicular fringes black. Worker.— I have never .seen a worker of this species. Smith's and Handlirsch's descriptions of this caste, however, show that it is much like the queen, except in size. Handlirsch says the wings of the worker are only slightly infuscate. Smith states that the ferruginous pile varies in brightness in diflferent individuals. Vachal states that the queen is like the worker. Male. — Unknown to me. Vachal describes this sex as follows: "The male has the hairs of the head black, mixed more or less with whitish ; the third and fourth antennal segments are subequal, being TRANS. AM. ENT. SOC. , XXXIX. 108 AMERICAN HYMENOPTERA. together a little longer than the fifth ; the hind metatarsus is rather thick, with very short hair." Dimensions .—h,en^\.h : queen, about 22 mm. ; worker (according to Smith and Handlirsch), 13 mm. to 14 mm.; male (according to Vachal), 17 mm. to 18 mm. Habitat. — Chile (Santiago), Argentina (Salta, Lara — 4,000 meters altitude, and Mendoza) and Peru. Apparently a highland species. This species seems to have its nearest ally in dolichocephahis.

Clypeus about as in fervidus male. Flagellum of antenna fully four times as long as scape ; fifth antennal segment much longer than third, third slightly longer than fourth ; all antennal segments between third and apical more or less noticeably arcuate. 77/(3ra.i-.— Clothed with black pile.

Genitalia. — Outer spatha (fig. 148) with hind margin broadly out- curved and evenly continuous with side margins ; the front margin deeply and evenly incurved, the anterior lateral corners evenly rounded ; the ventral surface, as a rule, only sparsely hairy. Inner spatha much like that of fervidus (fig. 101), but with hind margin of apical por- tion curving broadly outward in the midde. Claspers (fig. 171 and, fig. 196) in general much like those of fervidus and pennsylvafiicus, but readily separated from those of those two species by the strong ridging on the middle of the inner side of the ventral surface of the volsella and by the angular form of the inner side of the apex of the branch as seen from the dorsai side. Sagittae much like those of fervidus, but with the head strongly toothed on the outer side of its basal por- tion (strongly resembling dahlbomii 'm this respect).

This species, in my opinion, has its closest ally in opifex. It was probably on misdetermined specimens of this species that Smith (Cat. Brit. Hym. Brit.

Wittgs dark, zvith vio- laceous reflections. Malar space long. Queen. Head. — Rather elongate and black. Mandibles as in the Pratoruvi group. Malar space distinctly longer than its width at apex, about two-fifths as long as eye. Clypeus moderately punctate with rather coarse punctures. Third antennal segment somewhat longer than fifth, the fifth somewhat longer than the fourth. Thorax. — Clothed with black pile ; the very center of the dorsal disc naked and smooth. Abdomen. — Both dorsum and venter black. Hypopygium without median carina. Epipygium with a low, but distinct, longitudinal me- dian carina on its apical two-thirds. Wings. — Very dark and with violaceous reflections. Legs. — Dark and with black clothing. Worker. — Like the queen, but without median carina on epipygium. Male. — Like the females in coloration. Mandibles with black beard. Antennae very long, their segments feebly arcuate ; third segment very short, cone-shaped, nearly three-fourths as long as the fourth, the fourth three-fourths as long as the fifth. Hind tibiae flat on their outer sides and almost entirely naked in the middle of those sides ; metatarsi of the hind legs short haired. Hypopygium slightly bent up at the end and fringed with light, moderately long hairs. Genitalia.— Branch long ; squama divided into two lobes and con- siderably reached by the volsella drawn out into three nearly equal pro- cesses ; sagittse bent outward and hook-shaped at end. Dimensions .—Length : queen, about 21 mm. ; worker, 14 mm. to 18 mm. Spread of wings: queen, about 50 mm.; worker, 32 mm. to 40 mm. Width of abdomen at second segment : queen, about lOj mm. ; worker, about 7 mm. I have here redescribed the queen from a single specimen and the worker from three specimens. I have not seen the male, but have made up the description of that sex, here given, from a translation of Handlirsch's description. Habitat. — I have apparently certain records for this species as follows: Brazil (Rio de Janeiro, Rio Grande, Ypanema, Sao Paulo) ; Paraguay (Sapucay, Asuncion, Trinidad, Villa Encarnacion); Argentina (Tapia — 600 meters altitude); Peru (Callanga); Ecuador (Santa Inez) and Venezuela. Ducke has recorded it from Macapa, Brazil. Prof. T. D. A. Cockerel! gave the name kohli to this spe- TRANS. AM. ENT. SOC. , XXXIX. 112 AMERICAN HYMENOPTERA. cies because the name carbonarius had been preoccupied by B. carbonarius Menge, 1856, from Prussian amber. In the collection of specimens of South and Central American spe- cies before me, made up of specimens from a considerable number of different collections, there are only four specimens of this species while of niger there are fifty-two specimens. It seems probable, therefore, that both vehitimis and violace- ous were niger. It should be noted, however, that, when Handlirsch described this species, there were twenty-seven specimens of it in the collection of the Vienna Hofmuseum while there were apparently only thirty-six specimens of niger. So, while the chances seem to be in favor of Illiger's and St. Fargeau's having had niger, it is quite possible that they made their descriptions from specimens of either spe- cies or of both species mixed.

The worker is de- posited in the collection of the United States National Mu- seum and the male in the collection of the Massachusetts Agricultural College. These specimens are not in very good condition. The male is from Colombia and the worker from Pozuzo, Peru. Pile rather lons[ and rather fine. Head and malar space very long. Head and thorax black. First and last segtncfits of dorsum of abdomen and legs of females black. Intermediate dorsal abdominal segments of the females ferruginous-red Male abdomen all ferruginous-red above, except first segment. Wings dark. Queen. — I have never seen a queen of thi.s species, but I am sure from Smith's and Handiirsch's descriptions that this caste resembles the worker very closely except in size. Smith gives the length of the queen as eleven lines. Worker. Head. — Very elongate ; with only dark pile. Malar space much longer than its width at apex, about two-fifths as long as eye. Clypeus rather coarsely, but not very densely, punctate. Third antennal segment nearly as long as fourth and fifth together, the fifth slightly longer than the fourth.

Abdomen. — Dorsum: segment one clothed with black pile ; segments two to five, inclusive, all covered with ferruginous-red pile ; segment six dark. Venter mostly dark. Wings. — Rather strongly infuscate. Legs. — Coxae, trochanters, femora and tibiae all dark and with black pile. Metatarsi with fringes short. Male. Head. — Shaped and colored much like that of worker, but narrower and tapering more rapidly toward bases of mandibles. Mandibles with a rather heavy ferruginous beard. Malar space very much longer than its width at apex, about two-fifths as long as eye. Clypeus rather coarsely, but not densely, punctate ; sparsely punctate in middle of distal end. Thorax. — Dark, as in worker, but the pile finer than in that caste. Abdomen. — Dorsum: segment one dark; the remaining segments clothed with rather pale ferruginous pile. Venter mostly dark, but the apical fringes of the segments rather pale. TRANS. AM. ENT. SOC. , XXXIX. (15) 114 AMERICAN HYMENOPTERA. Genitalia. — Outer spatha much like that of dolichocephalus (fig. 148). Inner spatha like that of fervidus (fig. 101). Claspers long, but ap- parently powerful (fig. 168 and fig. 189), in general much like those of the other members of the Dunwucheli group ; branches, as seen from dorsal side, very broad and quadrate at apex ; squamae with inner lobe rounded at end and extending mesad far beyond inner margin of volsella, the outer lobe very broad and pointed at the apex on the side toward the middle line of the body; volsellae very broad, with sides nearly parallel throughout and with very large, prominent and curved apical projections, the margins of these projections being even and their apices sharply pointed. Sagittse with shafts long and curved out- ward somewhat in the middle, there being a prominent projection on the middle of the ventral side of each ; the heads short and foliaceous and curved ventrad and laterad from the shaft. Uncus, except to- ward the base, narrow and tapering gradually to the very narrow and recurved apex. Wings, — Light, somewhat infuscate. Legs. — Dark like those of worker. Outer faces of hind tibiae nearly flat and naked ; their front and hind fringes long, forming distinct cor- biculae. Hind metatarsi with no long fringes, their outer faces dis- tinctly concaved and bearing pubescence of two different lengths inter- mixed, the longer hairs being sparse.

Width of abdomen at second segment: worker, about 7 mm. ; male, about 7 mm. Habitat. — It seems certain that Fabricius' early record of this species from " North America " was incorrect. It does not seem to be a very common species anywhere and, if present in Central America, it must be very rare there. Prof. Cockerell has given us an uncertain record of it from Rio Nautla, Mexico. At all events, it is mainly a South Ameri- can form, and we have the following apparently certain records for it: Colombia, Venezuela, Peru (Pozuzo). It must also be present in Ecuador.

Claspers (fig. 147 and fig. 170) long, but thick and powerful in appearance ; branches with inner sides of their distal ends, as seen from dorsal side, sharply angled ; squams much like those of fervidus and pennsylvanicus ; volsellae more or less grooved longitudinally with a single groove (not always very definite) not far removed from each side margin, as seen from the ventral side, their apical projections large, triangular and prominent and usu- ally bearing several small, though noticeable, denticles (these, how- ever, are sometimes almost entirely absent) on their hind margins. Sagittae with shafts long and bent outward somewhat in the middle ; their heads very short, considerably foliaceous and turned ventrad, with a large, prominent, recurved tooth on the outer side of each.

(From Guerin's description, I judge they are sometimes somewhat longer than this. He described the largest as measuring 32 mm.); worker, 12 mm. to 18 HENRY J. FRANKLIN. 117 mm. ; male, 14 mm. to 17 mm. Spread of wings: queen, 50 mm. to 54 mm. ; worker, 33 mm. to 45 mm. ; male, 37 mm. to 42 mm. Width of abdomen at second segment : queen, 11 mm. to 13 mm. ; worker, 6 mm. to 9 mm. ; male, 7 mm. to 81 mm. The species is here redescribed from seven queens, six workers and six males. Habitat. — We have the following records of capture of this species: Chile (Santiago, Punta Arenas and Borja Bay at the Straits of Magellan); Argentina (Chubut in Patagonia); Brazil (Santos, Rio de Janeiro, San Pablo and Sao Paulo). I have myself seen specimens from all the localities men- tioned in Chile and Argentina. Cunningham (vide supra) states that the species is common at the Straits of Ma- gellan. This species is a very striking one on account of its color and size. It is easily the largest Bombus species in the Western Hemisphere. It is apparently quite constant in all its characters except that, in different specimens, the reddish pile varies in shade from a deep orange-ferruginous to a pale yellowish-ferruginous. It is probable that the deep orange- ferruginous is the normal color for the species and that speci- mens with the pale pile are faded. This species has its closest relative in dolichocephalus as is shown by the structure of the genitalia of the male. Kohli also seems allied. Bombus (Bombus) solus new species.

This is the male of one of four apparently distinct black forms present in South or Central America. I should have taken it for the male of kohli had not Handlirsch already described a male, which is unknown to me, for that species, from abundant material. It is possible that Handlirsch really erred in his association of the sexes of kohli. It is also possible that the male here described is a melanic speci- men of some species already known and does not represent a valid new species, though all the true melanic bumble-bees, which I have seen, have had some trace of the true colora- tion of the species to which they belonged, by means of which their true identity could be easily discovered.

Squamae shaped somewhat like those of pennsylvaniciis (fig. 66), but with outer lobe narrower and rather pointed at apex and with indentation between this lobe and the inner one deeper. Sagittae with shafts slightly bent outward in the middle and with heads shaped much like those of pul- latus and medius, their outer margins being distinctly, though not very deeply, serrate ; much longer and larger, in comparison with the claspers, than those of pullatus or vieditis, extending somewhat beyond the tips of the squamae and almost as far back as the tips of the vol- sellae. Claspers appearing much thicker, in proportion to their length, than m pullatus or niedius. Wings. — Dark and with violaceous reflections. Legs. — Some or all of the coxte and trochanters with a scattering of dirty whitish hairs, though mostly dark ; femora and tibiae black ; hind tibiae with outer faces convex and hairy throughout, with no long fringes and without a trace of corbiculte ; hind metatarsi with outer faces distinctly concaved and with no long fringes. Dimensio?is. — Length, 12| mm. to 15 mm. ; spread of wings, 33 mm. to 39 mm. This species is apparently most closely related to medius and pullatus, but it may be readily separated from those spe- cies by means of the differences in the genitalia already noted. This may be the true male of kohli. Bombus (BombiLs) brevivillus new species. This species has the same doubtful bibliography as that given to iiiger.

Entirely black. Malar space somewhat shorter than its width at apex, about one-fourth as long as eye. Clypeus moderately punctate, with rather coarse punctures. Third antennal segment longer than fifth and fifth longer than fourth. Thorax. — Entirely black. A noticeable, naked, smooth, shining area on center of disc. Abdomen. — Entirely black. Hypopygium without a median carina. Epipygium with a slight longitudinal median carina on its very apical portion. Wings — Very dark and with strong violaceous reflections. Legs. — Black. Worker. — Unknown. Male. — I think it possible that puUatns is the male of this species. See discussion following description of niger. Dimensions . — Length, about 24 mm. ; spread of wings, about 53 mm. This species is most closely related to mexicanus, and I do not feel certain that there is not a complete gradation between them. I have not succeeded in separating them structurally. I can distinguish brevivillus from niger only by its shorter and coarser pile. Both brevivillus and niger may be readily separated from kohli by the distinctly longer malar space of the latter. Bombus (Boinbiis) niger new species. ? Bombus velutinus Illiger, Magaz. f.

Of these specimens, three queens and two workers are deposited in the collection of the United States National Museum and one queen and two workers in the collection of the Massachusetts Agricultural College. The places of cap- ture of the queens were as follows : Colombia and Chiriqui (Boquete and Bogona). The workers came from the follow- ing places : Brazil (Pernambuco), Peru (Callanga), Chiriqui and Costa Rica (Carillo). St. Fargeau's specimens are lost, so it is impossible to tell whether his violaceus was this species or kohli or brevivilhis. Pile of medium length and texture. Entirely black. Malar space of a little more than average length Jllngs dark, with violaceous reflec- tions. Queen. Head. — Rather elongate. Entirely dark. Malar space somewhat shorter than its width at apex, about one-fourth as long as eye. Clypeus sparsely punctate, with rather coarse punctures and with numerous fine punctures also present. Third antennal segment longer than fifth, the fifth longer than the fourth. Thorax. — Entirely black. A rather large naked area on middle of dorsal disc, a considerable portion of this area being smooth and shining. Abdo}nen.—'Ent\ve:\Y black. Hypopygium without a medium carina. IVings. — Very dark and with strong violaceous reflections. Legs. — Black. IVorker. — Like the queen. Male — The queen and worker of this species are apparently less closely related to mexicanus than is the queen of brevivillus , and atratus appears less closely related to mexicanus than is pullatus. These facts suggest that pullatus may be the male of brevivillus, while atratus is possibly the male of niger. Dimensions . — Length : queen, 20 mm. to 24 ram. ; worker, 11' mm. to 17 mm. Spread of wings : queen, 48 mm. to 52 mm. ; worker, 29 mm. to 42 mm. Habitat. — British Honduras (Belize); Costa Rica (Carillo and La Estrellade Cartago); Chiriqui (Bogona and Boquete); Colombia; Venezuela (San Julian); Ecuador; Peru (Cal- langa); Brazil (Bonito in the Province of Pernambuco and St. Catharina) and Paraguay (Sapucay).

Type. — Described from a single male from Ecuador, de- posited in the collection of the United States National Mu- seum. Face with dark cinereous pile ; body otherwise almost entirely black. Malar space sotnewhat shorter than its width at apex. Third antc7inal segment distinctly shorter than the fourth ; the fifth much longer than the fourth. Wings dark and with distinct violaceous reflections. Gefii- talia with sagitto' tiot reaching quite as far back as the tips of the squamcs ; the volsellce reaching far beyond the heads of the sagittcs ; the sagittce with nearly straight shafts. Queen. — Brevivillus may be the queen of this species. Worker. — Unknown. Male. Head. — Face clothed with very dark cinereous pile (this pile is made up of long dark brown hair and shorter dirty whitish pile or down). Occiput dark. Ventro-lateral portions bearing brown pile. Malar space somewhat shorter than its width at apex, nearly one-fourth as long as eye. Clypeus, for most part, covered up with very dark cinereous pile. Third antennal segment distinctly shorter than fourth, the fifth much longer than the fourth. Thorax. — Clothed with entirely dark brown pile; a large area on dorsal disc and all but hind and side margins of scutellum naked, the pile apparently having been rubbed off. Abdomen. — Entirely dark. Genitalia (figs. 159 and 166). — Much like those of medius (see the comparison of the genitalia of these two species, following the descrip- tion of medius) . Sagittse with nearly straight shafts and with outer margins of heads nearly entire, scarcely serrate at all ; their heads ex- tending posteriorly but little beyond the long inner lobes of the squamae, these lobes reaching mesad far past the rounded projections on the inner sides of the volsellae to nearly even with the outer margins of the heads of the sagittte. Tips of volsellae reaching considerably beyond tips of squamae. Wings. — Dark and with distinct violaceous reflections.

This species is most closely related to medms, but appears to be distinct from it. B. atratus is certainly quite distinct from both and is possibly the male of niger. Incaru7n is also quite distinct from all these forms. Mexicanus is certainly distinct from ptdlatus. The volsellae of the genitalia of pid- latus have much wider apices and more hook-like apical pro- jections than do those of mexicanus, and the squamae of pul- latus have the outer lobe well developed and prominent while those of mexicamis do not.

His specimen came from Cayenne. I have not seen Cresson's type of medius. It is probably in the collec- tion of the United States National Museum. I have, how- ever, seen specimens labelled ''''medius'''' by Cresson, in the collection of the American Entomological Society, and those specimens were specimens of this species. The type locality (Utah), given for viedius by Cresson, is certainly incorrect. Among all the specimens, which I have seen from the west- ern United States, there was not one which could have be- longed to this species, and Prof. Cockerell states (Psyche, XII) that this species is not present in the western States, but is Mexican. Col. C. T. Bingham failed to locate Smith's type specimens of unifasciatus in the collection of the British Museum for me, and it is impossible to tell from Smith's de- scription whether his specimens belonged to viedhis or mexi- canus. They came from Guatemala (at 5,000 feet altitude), Costa Rica (Irazu at 6,000-7,000 feet altitude) and "San Francisco " at 4,500 feet altitude. Pile rather short and coarse atid considerably variable in coloration The typical form has the dorsum of the thorax yellow, zvith a broad black itiieralar band, and the third dorsal abdominal se,i(ment yellow, but is otherwise entirely dark in the females and also mostly so i7i the males, except for some light pile on the face and sotne ferruginous pile on the very apex of the abdometi. This typical form grades com- pletely i?ito a fortn which, aside from the third dorsal abdominal seg- ment, is entirely black in the fetnale caste and also mostly black iti the male, except for the ferruginous pile on the hypopygiuni and epipygium. Abdomen of fetnale rarely entirely black. 3Ialar space of females shorter than its width at apex, a little more than one-fifth as long as eye. Geni- talia with outer lobe of squaince well developed and rather pointed at tip. Queen. Head. — Entirely dark. Malar space distinctly shorter than its width at apex, a little more than one-fifth as long as eye. Clypeus moderately punctate, with mostly rather coarse punctures, the front part of the disc, however, with the punctures sparse. Third antennal segment longer than fifth, the fifth longer than the fourth. Thorax. — Dorsum yellow in front and on scutellum, with a very broad black band between bases of wings (this band is distinctly more than half as wide, from front margin to rear margin, as it is long, from wing base towing base). Yellow pile extending down, from HENRY J. FRANKLIN. 125 front part of dorsum, to somewhat below level of bases of wings ; mesopleura otherwise entirely dark. Metapleura and sides of median segment entirely dark. Abdomefi. — All black, except third dorsal segment. This segment clothed, for most part, with yellow pile, but its very basal portion usu- ally with yellow replaced somewhat by very short black hairs. Wings. — Dark and usually with strong violaceous reflections. Legs. — Entirely dark. Hind margin of posterior metatarsi usually rather suddenly arcuate near the base, but nearly straight throughout the greater part of its length. Worker. — Like queen, but with malar space but little, if any, more than one-fifth as long as eye. Short black hair usually not showing on basal portion of third dorsal abdominal segment. Black interalar band sometimes not more than half as wide, from front margin to rear margin, as long, from wing base to wing base. Male. Head. — Face clothed with mostly cinereous pile (this pile is made up of a mixture of long dark hairs and shorter whitish pile or down) , this clothing being darkest above the bases of the antenna and lightest over the clypeus. Occiput either bearing a mixture of dark and yellow hairs or with a triangular patch of pure yellow pile, this patch being extended, on each side, along the hind margin of the head, down onto the sides somewhat, behind the upper ends of the eyes. Ventro-lateral portions with a slight sprinkling of yellow hairs. Malar space somewhat shorter than its width at apex, about one-fifth as long as eye. Clypeus mostly covered up with dirty whitish pile, there being only a scattering of dark hairs admixed. Third antennal segment dis- tinctly shorter than fourth, the fifth much longer than the fourth. Thorax. — Coloration of pile much like that of females, but with the yellow pile sometimes reaching down, from the front part of the dor- sum, on the mesopleura, as much as half the distance from the bases of the wings to the bases of the legs. Each side of metanotum bear- ing a tuft of yellow pile just behind the base of the hind wing. Inter- alar band about half as^wide as long. Abdomen. — Dorsum: segmentsjone and two entirely black ; segment three clothed entirely with yellow ; segment four with basal portion covered with yellow and apical portion with black pile ; segments five and six entirely black ; segment seven with some short black hairs on basal portion and on middle of apical portion, but otherwise clothed with ferruginous pile. Venter mostly dark, but the apical margins of most of the segments fringed with pale ferruginous pile, the apical fringe of the hypopygium being rather strongly ferruginous. Geiiitalia (figs. 162 and 163). — Much like those of niexicantis (figs. 160 and 164), but with apices of branches distinctly angled on their inner sides, as viewed from above ; outer margin of head of sagitta distinctly serrate ; outer lobe of squama well developed and rather pointed at apex. TRANS. AM. ENT. SOC, XXXIX. 126 AMERICAN HYMENOPTERA. Wind's. — Strongly infuscate, but much lighter than those of queen and considerably lighter than those of most workers ; with practically no violaceous reflections. Legs. — Mostly dark; the trochanters and coxae and the very lowest portions of the meso- and metapleura with a strong sprinkling of dirty whitish hairs. Hind tibite with outer faces convex and hairy through- out, with no long fringes and no trace of corbiculse. Hind metatarsi with outer faces distinctly concaved and with no long fringes. Dinieyisions . — Length : queen, 20 mm. to 21 mm. ; worker, 10 mm. to 17 mm. ; male, nearly 14 mm. Spread of wings : queen, 42 mm. to 47 mm. ; worker, 28 mm. to 37 mm. ; male, 33 mm. to 34 mm. The species is here described from six queens, numerous workers and two males. The typical species, above de- scribed, grades completely into the following forms, speci- mens of which are before me : Color VariaJtt i — Worker like typical form, but with scutellum and front part of dorsum of thorax bearing only a little yellow pile, this being thoroughly mixed with black hairs. About 12 mm. long. A single worker from Chiriqui. Color Variant 2 — Queen like typical form, but with scutellum entirely black ; with only a little yellow pile on the front part of the dorsum of the thorax, this having a slight admixture of black hairs. About 18 mm. in length. A single specimen from Brazil (Sao Paulo). Color Variant 3. — Worker like typical form, but with thorax entirely black — thus completely paralleling w^,rzVa//«j in coloration. About 12 mm. in length. A single specimen from Chiriqui. Color Variant 4. — Like Color Variants, but with yellow pileon third dorsal abdominal segment confined to posterior portion of that segment and not reaching its side margins. About 15 mm. in length. A single worker from Paraguay (Sapucay). Color Variant 5. — Worker like typical worker, but with abdomen entirely black. Length about 12 mm. A single specimen from Para- guay (Sapucay). Male Color Variant i. — Like typical male, but with interalar band slightly more than half as wide, from front margin to rear margin, as long, from wing base to wing base, and with second, third and fourth dorsal abdominal segments entirely covered with yellow pile and with epipygium clothed with entirely ferruginous pile. Hind femora with scattering of yellow hairs on lower side of middle portion. Ventro- lateral portions of head bearing a mixture of dark and yellow hairs. Length about 19 mm. A single specimen from Boquete, Chiriqui (3,500 feet altitude). Male Color Variant 2. — Like typical male, but with ventro-lateral portions of head entirely dark and with yellow pile on front part of HENRY J. FRANKLIN. 127 dorsum of thorax and on scutellum with a slight admixture of black hairs and not extending down on the sides, in front, to much below the level of the bases of the wings ; black interalar band distinctly more than half as wide as long, the tegulas scarcely dipping at all into the yellow pile in front ; metanotum bearing no yellow pile ; dorsum of abdomen with third and fourth segments entirely covered with yel- low pile ; sixth segment having an admixture of ferruginous hairs, this admixture being very slight on the middle of the segment, but very strong on the extreme sides ; seventh segment clothed with entirely ferruginous pile. Length about 15 mm. A single specimen from Boquete, Chiriqui (3,500 feet altitude). Male Color Variant j. — Like Male Color Variant 2, but with only a faint sprinkling of yellow hairs on the middle of the front part of the dorsum of the thorax and on the scutellum ; face with very dark cinereous pile throughout ; occiput entirely dark ; epipygium clothed like that of typical male. Length about 16 mm. Two specimens from Ecuador. Male Color Variant 4. — Like Male Color Variant 3, but with face having cinereous pile about as in typical male and with thorax entirely black. Length about 13 mm. A single specimen from Ecuador. Male Color Variant §. — Like Male Color Variant 4, but with head en- tirely dark ; third dorsal abdominal segment clothed mostly with yel- low pile, but with the yellow hair replaced by a thin clothing of short black pile on its very basal portion ; fourth dorsal segment bearing black pile on its apical portion, this being bordered in front by a nar- row line of yellow hairs, the very basal portion of the segment being thinly clothed with short black hairs as in the case of the third seg- ment; epipygium clothed with entirely ferruginous pile; venter almost entirely dark, except hypopygium, this being fringed apically with rather strongly ferruginous pile. Length about 16 mm. A single specimen from Ecuador. Habitat. — Mexico (Orizaba, one male ; Rio Nautla, one worker ; Otoyac, one worker ; Coatepec, one worker); Guate- mala (Department of Solola, Olas de Moka, one male, three workers and four queens); Chiriqui (Boquete, two workers and two males); Ecuador (seven workers); Brazil (Minas Geraes, one worker; Sao Paulo, one queen); Paraguay (Sa. pca y, one queen and five workers); Mexico (one queen). There seems to be a slight variation in the length of the malar space of the queen. This species seems to have its nearest ally in niexicanus. The females may be separated from those of niexicanus by TRANS. AM. ENT. SOC. , XXXIX. 128 AMERICAN HYMENOPTERA. their somewhat shorter malar space and by the hind margin of their posterior metatarsi rather more suddenly arcuate near the base. The males may be separated from those of mexicanus by the differences in the structure of their geni- talia, particularly of the squamae, and by the ferruginous pile on their last dorsal abdominal segment. The genitalia of ynedius may be separated from those of pidlahcs by the somewhat narrower apices of their volsellas, with their some- what less hood-like apical projections, and by the distinctly serrate outer margins of the heads of their sagittae. Pullatus, medius and mexicamis all agree in having the tips of the volsellae of their genitalia extend considerably beyond the squamae and far beyond the heads of the sagittae. In this respect, these species all differ markedly from atratus. The yellow pile on the specimens of inediiis before me varies from pale straw color to a good deep yellow. It seems possible that medius may even grade into a com- pletely black form, and I do not feel certain that ntger, which seems very closely related, is not, in reality, such a gradation of this species.

Hypopygium without a median carina. Surface of epipygium elevated somewhat in middle of very apical portion. JVings. — Very dark and with strong violaceous reflections. Legs. — Entirely dark. Worker. — Like queen, but with slightly lighter wings. Malar space apparently somewhat shorter, in proportion to length of eye, than that of queen.. Male. Head. — Mostly dark ; face with mostly cinereous pile (this pile being darkest above the bases of the antennae, there being a much more sparse admixture of the long dark hairs on the clypeus); occiput .sometimes with a faint admixture of yellow pile.

Venter mostly dark, but with apical fringe of last seg- ment ferruginous and the fringes of some other segments tinged with the same color. Genitalia. — Outer spatha like that of sonorus (fig. 32) .

It is absent, or practically so, in fnonteztonc^ , carolinus and dahlbomii); extending considerably beyond tips of squamaj. Squamse extending a little beyond heads of sagittte ; their outer lobe almost wanting, being very short and broadly rounded, but the inner lobe well developed and extending mesad considerably beyond the inner margin of the volsella. Shafts of sagittse bent out- ward somewhat in the middle and the outer margins of their heads entire or nearly so, not distinctly serrate. Uncus very broad in the middle, but tapering rapidly to the recurved apex. Wi7!gs. — Generally somewhat lighter than those of workers and con- siderably lighter than those of queens, with only slight violaceous reflections. Legs. — Mostly dark, though often with a considerable scattering of dirty whitish hairs about their bases. Hind tibiae with outer faces con- vex and hairy throughout, without long fringes or trace of corbiculae. Hind metatarsi with outer faces distinctly concaved, with no long fringes. Dimensions. — Length : queen, 20 mm. to 24 ram. ; worker, \\\ mm. to 15j mm. ; male, I3| mm. to 15^ mm. Spread of wings : queen, 47 mm. to 51 mm. ; worker, 29 mm. to 33 mm. ; male, 32 mm. to 36 mm. The species is here redescribed from five queens, numer- ous workers and four males. Habitat. — Mexico; Guatemala (Department of Solola — Olas de Moka — seven workers); Costa Rica (San Jose, three workers); Chiriqui (Boquete, one worker; Bogona, one queen); Ecuador (four queens, one worker and four males). This species is possibly most closely related to brevivilhis, which has the same short, coarse pile in the queen caste and which may possibly grade into it. With this possible excep- tion, medius is its closest ally. The females of mexicaniis have a slightly longer malar space than do those of medius. The males of mexicanus apparently never have ferruginous pile on the last dorsal segment of the abdomen, while those of mediiis appear to always have it. See the discussion, fol- lowing the description of medius, for other points of differ- ence between the two species. Also see the discussion, fol- lowing the description of pjiUatus, for points of diiiference between that species and mexicanus. The yellow pile, on the specimens of this species before me, varies in shade from pale straw to a good deep yellow. HENRY J. FRANKLIN. 131 Bombiis (Boml)us) incarum new species. ?

Types. — Described from five queen cotypes (three of these from Chanchamayo, Peru, one from Callanga, Peru and one from Boquete, Chiriqui), of which four are deposited in the collection of the United States National Museum and one in the collection of the Massachusetts Agricultural College ; from sixteen workers (fourteen from Chanchamayo, Peru and two from Callanga, Peru), of which fourteen are de- posited in the collection of the United States National Mu- seum and two in the collection of the Massachusetts Agri- cultural College ; from one male, from Chanchamayo, Peru, deposited in the United States National Museum. Pile coarse and rather short Dorsum of thorax yellozv, with black band between bases of wings. Pleura mostly black. Abdomen with third dorsal segment yellow, otherwise black Legs black. Wings dark. Head of females black atid of males mostly dark. Malar space long. Queen. Head. — Rather elongate. Face entirely black. Occiput sometimes entirely black and sometimes with a triangle of nearly pure (not mixed with black) yellow pile, but usually dark with a faint ad- mixture of yellowish hairs. Sides entirely dark. Malar space nearly as long as its width at apex, nearly one-third as long as eye. Clypeus, for most part, finely punctate, with scattering coarse punctures, but with a considerable area on middle of front portion smooth and shin- ing. Third antennal segment longer than fifth, the fifth longer than the fourth. TRANS. AM. ENT. SOC, XXXIX. 132 AMERICAN HYMENOPTERA. Thorax. — Dorsum covered with yellow pile, except for black band between bases of wings (this baud is scarcely half as wide from front to rear as it is long from wing base to wing base, and, in some cases, it is not well defined, there being a more or less strong admixture of yellow hairs with the black). Mesopleura with yellow pile extending down from front part of dorsum to some distance below level of bases of wings, but for most part clothed with black pile. Metapleura and sides or median segment entirely dark. Abdometi. — Third dorsal segment clothed with yellow pile, otherwise entirely dark. Hypopygium without a median carina. JVing'S. — Very dark, with strong violaceous reflections. Leg's. — Entirely black or brown. Hind margins of posterior meta- tarsi rather evenly arcuate from base to apex. Worker. — Like the queen, but with somewhat lighter wings. Cly- peus sparsely punctate, with mostly coarse punctures. Male. Head. — Face, for most part, clothed with cinereous pile (this pile is a mixture of long dark brown hairs and shorter whitish pile or down). Occiput covered with a triangle of nearly pure yellow pile. Sides of head mostly dark. Malar space fully as long as its width at apex, nearly one-third as long as eye. Clypeus, except on middle of front portion, largely covered with cinereous pile. Third and fourth antennal segments subequal in length, the fifth longer than either. Thorax. — Coloration of dorsum like that of queen and worker, but the black interalar band very poorly defined, there being a very strong admixture of yellow hairs with the black. Yellow on upper portions of mesopleura extending far below level of bases of wings ; their lower portions, however, dark. Extreme end of metanotum bearing a tuft of yellow hair behind the base of each hind wing. Metapleura and sides of median segment dark. Abdomen. — Dorsum: segment one entirely dark ; segment two dark, except for a small amount of yellow pile on each hind corner ; segment three clothed entirely with yellow pile ; segment four mostly dark, but with some yellow hair on basal margin, especially at sides; segments five and six black. Venter black. Genitalia (figs. 184 and 187). — Apices of branches, as seen from dorsal side, acute angled on side toward median plane of body. Vol- sellae with apical projections much broader and more quadrangular than usual. Squamae greatly elongated and somewhat curved, with tips blunt pointed, reaching considerably beyond tips of volsella;, and curving around behind ends of sagittte ; the inner lobe absent. Sagitta; with shafts distinctly bent outward in middle ; heads very elongate foliaceous and downward curved, with very tips narrowed and curved mesad somewhat and with outer margins almost entii-e, only very slightly serrate. Wings. — Considerably lighter than those of queen, without notice- able violaceous reflections. HENRY J. FRANKLIN. 133 Legs. — Pile all dark. Hind tibiae with outer faces convex and hairy throughout, though rather sparsely so toward distal ends ; fore and hind fringes not very long and not forming corbiculse. Hind meta- tarsi with outer faces distinctly concaved, without long fringes. Diyneiisions. — Length: queen, 21 mm. to 25 mm. ; worker, 12 mm. to 18 mm. ; male, about 15 mm. Spread of wings: queen, 47 mm. to 49 mm. ; worker, 30 mm. to 38 mm. ; male, about 35 mm. Habitat. — Peru (Callanga and Chanchamayo); Chiriqui (Boquete); British Guiana (Georgetown); Surinam; Para- guay (Sapucay); Brazil (Rio Grande do Sul). This species is apparently related to viedius, niger, pullatiis and atr-atus. Most of the workers before me and the male have been immersed in some liquid, the pile being badly matted and the yellow being faded out to a pale straw color. The yellow of all specimens in good condition (including most of the queens and two of the workers) is a fairly deep rich yellow. The queen and worker of this species may be separated from the females of ynedius by the difference in the arcuation of the hind margin of the posterior metatarsi. Medhis has this margin more suddenly arcuate toward the base than does incarum, the latter species having it more nearly evenly arcu- ate from base to apex. Furthermore, the black interalar band of mcditis is more than half as wide, from front margin to rear margin, as it is long, from wing base to wing base, which is not the case with incarum. The male of incariim may be readily separated from all other males known to me by means of the greatly elongated squamae of its genitalia. Boiubus (Bombus) sououiie Howard. Bombus sononus Howard, Insect Book, 1904, Plate 2, fig. 7, 9 . Type. — The queen which Dr. Howard figured is the type of the species. I here describe the queen from eight speci- mens, seven of which, including the type, are deposited in the collection of the United States National Museum and one in the collection of the Massachusetts Agricultural Col- lege. The worker is described from six specimens (cotypes of this caste), of which one is deposited in the collection of the Massachusetts Agricultural College and five in the col- TRANS. AM. ENT.

Male. Head. — Elongate. Face mostly dark, but with a noticeable admixture of pale yellow pile about bases of antennae and on clypeus. Occiput sometimes entirely dark and sometimes with a noticeable ad- mixture of yellow hairs. Ventro-lateral portions mostly dark, but with some pale hairs admixed. Malar space distinctly longer than its width at apex, between one-third and one-fourth as long as eye. Cly- peus with central and front portions of its disc naked and, for most part, sparsely punctate, the remaining portions rather thinly clothed HENRY J. FRANKLIN. 135 with a mixture of dark and pale pile. Third antennal segment longer than fourth, but shorter than fifth. Thorax. — Coloration of pile much like that of females, but the meso- pleura covered with pale yellow pile to the bases of the legs ; upper portion of metapleura and sides of median segment also with mostly whitish yellow pile. Abdotnen. — Dorsum : segments one to five, inclusive, covered with yellow pile ; segment six either entirely clothed with yellow pile or with the very apical portion bearing black pile ; segment seven black and with black pile, but sometimes with a slight admixture of yellow hairs toward the sides. Venter mostly dark, but with the lateral por- tions of the apical fringes of most of the segments whitish. Genitalia. — Outer spatha very much like that of B. penvsylvanicus (fig. 126). Inner spatha much like that of peniisylvanicus (fig. 132), but without a fenestra in the specimen before me. Claspers short and powerful in appearance (fig. 156); the branches, as viewed dorsally, with their apices broadly rounded and rather quadrate in form ; vol- sellae with very large, prominent and triangular apical projections and with a large and prominent rounded protuberance on the inner side of each, somewhat beyond its middle. Squamae strongly bilobed, the two lobes being of about equal size ; outer lobe strongly pointed and reaching nearly as far as distal end of volsella ; inner lobe rounded at apex and extending mesad far beyond inner margin of volsella. Sagittae and uncus much like those of fervidus (fig. 102). IVings. — Much lighter than those of queen, only slightly iufuscate ; about like those of the fervidus male. Legs. — Coxae all with considerable whitish pile ; trochanters mostly dark, but sometimes with a few pale hairs ; femora all with much pale hair, this color usually extending along their entire length, at least on one side ; fore tibiae dark : middle and hind tibia3 sometimes almost entirely dark, but often with a considerable ferruginous tinge to their short hairs ; outer faces of hind tibiae convex and rather evenly hairy, there being no trace of corbiculae.

Width of abdomen at second segment: queen, 8 mm. to 8', mm. ; worker, 5 mm. to 6 mm. ; male, 5 mm. to 6 mm. Habitat. — All the specimens of this species, seen by me, came from Mexico. One worker was from Eslava. Seven of the queens (including the type), four of the workers and the two males were collected by C. H. T. Townsend, in Meadow Valley, head of Rio Piedras Verdes (six miles south TRANS. AM. ENT. SOC. , XXXIX. 136 AMERICAN HYMENOPTERA. of Colonia Garcia), Sierra Madre of western Chihuahua — about 7,000 feet altitude. This species is a close ally of fervidus and may be a sub- species of that species. It may be distinguished from fervi- dus by the dark pleura of its females and by the sixth dorsal abdominal segment of its males either entirely or mostly covered with yellow pile. The yellow pile of sonomce is of a distinctly darker and richer shade than that of fervidus, the yellow of fervidus usually being nearly a pale clay-yellow while that of sononitr is usually light old gold. The outer lobe of the squamae of the genitalia of the typical male of sonomce is much more pointed than is that of the typical fer- vidus male, but with fervidus this seems to be a somewhat variable character.

The specimens before me came from Brazil and Paraguay. Handlirsch (vide supra) records this species from Mexico, but his record needs confirmation. This species is apparently allied to steindachneri and me- dius. It seems to be comparatively constant in its characters. The yellow pile is pale straw-color.

Pile rather short and rather coarse. Malar space short. Head mostly dark. Dorsum of thorax yelloiv, with a broad black ivteralar band. Mesopleura mostly yellow. Dorsum of abdomen yellow, ferru- q^inous and black. Wings rather light. Legs black. Queen. Head. — Short for its width. Face mostly black, but with a faint sprinkling of short pale pile intermixed with the black hair on the region around the bases of the antenna;. Occiput with mostly black pile, but with an admixture of pale yellow hairs, especially on the very hind margin. Sides of head behind eyes entirely dark. Malar space HENRY J. FRANKLIN. 139 considerably shorter than its width at apex, slightly less than one- sixth as long as the eye. Clypeus shining and rather sparsely and delicately punctate. Ocelli not far below supra-orbital line, slightly above narrowest part of vertex ; lateral ones somewhat nearer to mar- gins of eyes than to each other. Flagellum of antennas about one and two-thirds times as long as scape ; third antennal segment equal to fourth and fifth taken together, the fifth scarcely longer than the fourth. Thorax — Dorsum yellow, but with a very broad and well defined black interalar band (this band being distinctly, but not greatly, more than half as wide, from front to rear, as it is long, from wing base to wing base, and of nearly equal width all the way across, though slightly narrower toward the bases of the wings) ; middle of disc with a longitudinally elongate area, large enough to be very noticeable to the naked eye (this area being within the black interalar band), naked, mostly smooth and shining. Mesopleura often covered with yellow pile very nearly to the bases of the legs and always with the yellow extending down as far as two-thirds of the distance from the level of the bases of the wings toward the bases of the legs. Metapleura sometimes clothed for most part with yellow pile and sometimes with only their very upper ends bearing yellow hair. Sides of median seg- ment sometimes entirely dark, but often with considerable yellow hair. Abdomen. — Dorsum : segment one yellow ; segment two yellow on basal middle, but with ferruginous pile on the extreme sides and along the hind margin, the yellow patch narrowing toward the front margin on the sides of the segment ; segment three ferruginous ; segment four with some ferruginous pile and a few black hairs on the very middle, at least at the base, but for the most part clothed with yellow pile ; segment five black, but with a few yellow hairs on the extreme sides ; segment six dark.

Dimensions . — Length, 14 mm. to 15j mm. ; spread of wings, 34 mm. to 36 mm. ; width of abdomen at second segment, 7 mm. to 81 mm. This species has its closest relative in nifocinchis, of which it may indeed be only a subspecies. I have been unable to separate it structurally from nifocinctus, but it may readily be separated from that species, as it is known to me, by its darker occiput and its much wider and better defined black TRANS.

The ferruginous pile is somewhat variable in shade, but, when the shade is deepest, it is perhaps best described as dark ferruginous. Bombiis (Bonil)ias) ramoiiensis new species. Type. — Described from a single male, deposited in the col- lection of the United States National Museum. Type locality, San Ramon (Costa Rica?). Malar space very short. Pile rather short and rather fine. Ocelli separated from tnargins of eyes by less than half their own diameters. Third and fifth atitennal segments subeqnal in length. Mostly dark. Yellow or whitish pile present on face, sides of head behind eyes, front part of thoracic dorsum, sctitelluni and first, sixth and seventh dorsal abdominal segments. Queen and worker. — Unknown. Male. Head. — Rounded. Face, from front margin of clypeus to fully half-way between bases of antennae and ocelli, mostly clothed with yellow pile ; extreme sides of face, close to margins of eyes, how- ever, with dark hair. Ventro-lateral portions of head with a notice- able amount of yellow pile intermixed with the black. Malar space scarcely half as long as its width at apex. Clypeus almost entirely covered with a rather thick clothing of yellow pile. Ocelli large, placed at more than one-third of the distance from the supra-orbital line towards the bases of the antennae ; lateral ocelli removed from margins of eyes by less than half of their own diameter ; space be- tween eyes somewhat narrower above ocelli than at ocelli. Eyes greatly swollen and bulging out from sides of head, the vertex being distinctly depressed between them. Third and fifth antennal seg- ments subequal in length, the fourth distinctly shorter than either. Thorax. — Dorsum mostly black, but with a band of yellow pile across the front part (this band reaches down on the mesopleura to somewhat below the level of the bases of the wings) and the scutellum heavily fringed with yellow behind. Mesopleura mostly dark, but with an inconspicuous patch of yellow pile on their lower portion toward the bases of the legs, and with some yellow on their upper por- tion in front (the extension of the yellow band on the front part of the dorsum). Metapleura dark. Sides of median segment mostly dark, but with a slight admixture of pale hairs. Abdomen. — Dorsum : segment one clothed mostly with j'ellow pile, but with some dark hair in middle ; segment two mostly dark, but with some yellow hair on basal middle ; segments three and four entirely dark ; segment five mostly dark, but with whitish pile on hind corners ; segments six and seven largely clothed with white pile, HENRY J. FRANKLTN. 141 but dark in middle. Venter mostly dark, but with considerable pale pile on apical half. Wings. — Very moderately infuscate ; veins so much darker than membranes as to contrast considerably with them ; much the lightest in the region beyond the veins, being, in this portion, almost clear transparent. Legs. — Mostly dark ; hind femora and trochanters with a sprinkling of yellow hairs on their lower sides ; middle tibise with a noticeable amount of whitish hair on their inner sides and with hind fringes faintly ferruginous. Hind tibise with outer faces slightly convex and sparsely hairy on apical two-thirds; their fore fringes very moderate and their hind ones long. Hind metatarsi between three and one-half and four times as long as their greatest width ; their outer faces strongly concaved ; their hind fringes long and of dark and ferrugin- ous hairs mixed. Dimensions. — Length, about 16^ mm. ; spread of wings, about 39 mm. ; width of abdomen at second segment, about 8 mm. This species seems to have its closest ally in {raternus. It can be separated structurally from any other Bombiis male known to me. Its pile is of a character somewhat similar to that of the male of 7-obustus. The position of the ocelli and the degree of tumidity of the eyes are, however, dis- tinctly diiTerent in the two species. This male may possibly be a color variant of the unknown male of volucelloides, though this seems highly improbable. The yellow pile of this spe- cies is a pale, dirty, straw-yellow.

Males similar to TRANS. AM. ENT. SOC. , XXXIX. 142 AMERICAN HYMENOPTERA. females in coloration, but with some yellow hair 07i face and occiput and with yellow pleura. Queen. Head. — Rather broad and rounded in general form, with only dark pile. Malar space distinctly wider at apex than its length, not over one-sixth as long as eye. Clypeus, for most part, rather strongly and coarsely punctate, but sparsely so (almost smooth) toward the middle line. Ocelli large and distinctly below supra-orbital line, in narrowest part of vertex (distinctly Bonibias in character). Third antennal segment about as long as fourth and fifth taken together. Thorax. — Front part of dorsum covered with yellow pile back to tegulse ; a broad black band between bases of wings (this band is slightly more than half as broad, from front to rear, as it is long, from wing base to wing base) . Tegulae sometimes completely surrounded by black pile, but usually with yellow pile in contact with them on the upper side of their front end. Center of disc with a considerable area completely naked, the middle portion of this area being smooth and shining. Scutellum covered with yellow pile, the front median por- tion often being somewhat naked. Pleura, from bases of wings to bases of legs, and median segment black and with dark pile only (rarely there is a very slight sprinkling of yellow hairs on the pleura and on the sides of the median segment) . Abdomen. — Dorsum : segments one and two clothed with yellow pile ; segments three, four and five densely covered with rich ferru- ginous-red pile; segment six clothed with short ferruginous-red hairs. Venter mostly dark, but with the apical fringes of the three apical segments more or less ferruginous. Hypopygium without a median carina. Wings. — Dark, as in B. crotchii Cress., and with distinct violaceous reflections. Legs. — Coxae, trochanters, femora and tibiae all black and bearing no light pile ; corbicular fringes black. Worker. — Much like queen, but with wings lighter and usually with- out violaceous reflections. Corbicular fringes proportionately longer than those of queen. Male. Head. — Black, but with face below bases of antennae rather strongly yellow, with black hairs intermixed ; sides behind eyes black ; occiput rather weakly covered with yellow hairs. Malar space very short, not much longer than pedicel of antenna. Ocelli large and placed far below supra-orbital line. Eyes greatly swollen, bulging out from sides of head. Antennae with third segment fully as long as fifth, the fourth much shorter than either. Thorax. — Dorsum entirely and densely covered with yellow pile, except for a broad, but rather indefinite (due to intermingling of yel- low hairs) , black band between bases of wings. Pleura covered with yellow pile to bases of legs. Abdomen. — Dorsum : first three segments covered with yellow pile, HENRY J. FRANKLIN. 143 the remaining segments shading off toward the apex of the abdomen into rich ferruginous-red. Venter black at base, but, beginning a little behind the middle, the apical margins of the segments fringed more or less heavily, especially toward the side margins, with ferru- ginous hairs. Legs. — Dark and with dark clothing. Dimensions. — Length : queen, 19 mm. to 24 mm. ; worker, 13 mm. to 17 mm. ; male, \1\ mm. Spread of wings: queen, 47 mm. to 49 mm.; worker, 30 mm. to 32 mm. Width of abdomen at second seg- ment: queen, 11 mm. to 12 mm.; worker, 6 mm. to 6^ mm. I have here redescribed the queen from ten, and the worker from two, specimens. The description of the male here given is simply a transposition of the original description of that sex. Habitat. — The records for this species, so far known, are all Mexican (Orizaba, Takubaya, Mexico City, Eslava and Meadow Valley — head of Rio Piedras Verdes — six miles south of Colonia Garcia, in the Sierra Madre of Western Chihuahua, at an altitude of about 7,000 feet). The male type is not in good condition, the pile of the ab- domen being badly matted. It seems probable that, in a good fresh specimen, the coloration of the abdomen of this sex would more nearly approximate that of the abdomen of the females. This species apparently has its closest ally in crotchii. Boinbus (Boiubias) braohyceplialus Handl. ? Bombus diligefis Smith, Journ. of Entom., I, 1861, p. 154, n. 5, 9 . ? " " Cresson, Proc. Ent.

Head and thorax black {fro7it part of male thorax often with jnore or less light or yellow pile) ; abdomen with basal seg- ments black and apical segments ferruginous. Wings dark. Heads of queen and worker short and broad. Male with large eyes. I have never seen either the queen or the worker of this species. Handlirsch described them together as follows : "Head short and broad; clypeus strongly arched, thickly and coarsely punctate, somewhat less so in the middle ; labrum deeply im- pressed in the middle ; malar space nearly one-half shorter than it is broad at the end ; mandibles and antennae as in dolichocephabis . Hind metatarsus moderately pointed at the end. Hypopygium with- out a carina." He also remarked concerning them as follows : " The queen and worker agree as strikingly with the foregoing spe- cies " {dolichocephabis) " in the black color of the body with the red end segments as in the dark brown-black wings with their violaceous reflections." Male. Head. — Broadly rotund-triangular. Pile entirely dark. Malar space but little more than half as long as its width at apex. Clypeus coarsely and densely punctate and very thinly clothed with rather long black hairs. Ocelli large and placed squarely in the narrowest part of the vertex, at about one-third the distance from the supra-orbital line towards the bases of the antennae (eyes not converging above them at all), the lateral ones separated from the inner margins of the eyes by distinctly less than their own diameter. Eyes swollen a little less than those of crotchii male, slightly more than those of males of morrisoni and separatus. Third and fifth antennal segments about equal in length. Thorax. — Center of disc of dorsum bare (the greater part of the dorsum has the appearance of having the pile rubbed off more or less), smooth and shining. Pile all dark, apparently usually pure black, but sometimes brown (the anterior portion of the dorsum of one specimen has a strong admixture of yellow hairs and probably there is sometimes a distinct yellow band in that region). Abdomen. — Dorsum : segments one, two and three with black pile ; basal portion of segment four with black pile and its apical portion clothed like segments five and six ; segments five and six bearing only ferruginous-red or light ferruginous pile. Venter mostly dark, but with the apical fringes of the three apical segments more or less strongly ferruginous. Hypopygium broadly emarginate at apex. Genitalia. — Outer spatha short and broad, resembling considerably that of separatus (fig. 29) , but with anterior margin much less strongly incurved and side margins not incurved in front ; middle of apical por- tion of ventral surface with only a few hairs and these short and in- HENRY J. FRANKLIN. 145 conspicuous. Inner spatha much like that of fervidus (fig. 101), but with sides of apical portion outcurved. Claspers (fig. 175 and fig. 188) appearing moderately short ; with branches rather narrow and evenly rounded at distal end as seen from dorsal side ; volsellae reaching con- siderably beyond tips of sagittae and squamae, their apices but slightly rounded, appearing almost squarely truncate, and the middle of the inner side of each protruding inward, toward the middle line of the body, in a single broadly rounded projection ; squamae with outer lobe much larger than inner one and narrowing rapidly towards its nar- rowly rounded apex, the inner lobe not reaching, or scarcely reaching, mesad beyond the inner margin of the volsella. Sagittae with shafts bent outward somewhat in the middle and with heads irregularly folia- ceous-sickle shaped, the base of the sickle being very broad and the apex pointed. Uncus broad and tapering rather rapidly towards its distal end, the recurved tip being rounded and so depressed longitu- dinally in the middle as to appear channelled. Wittgs. — Rather dark. Legs. — Dark and with dark pile. Hind tibiag with slightly convex outer faces, these faces being mostly bare, but with a few scattering hairs; the front fringe of these tibiae short, but the hind fringe (of hairs) rather long. Hind metatarsi about three and one-half times as long as their greatest width ; their hind fringes long and black ; their outer faces nearly flat. Dimensions . — Judging from the fact that this species has been long confused with B. dolichocephalus and that Handlirsch did not give measurements for it, it seems not improbable that the females of this species are, on the average, of about the same size as are those of B . dolichocephalus. If this is the case, the queens of this species are twenty or more millimeters in length. I have here described the male from two specimens, the measurements of which are as follows: Length, 12 mm. to 13 mm. ; spread of wings, 30 mm. to 33 mm. ; width of abdomen at second segment, 7 mm. to 7| mm. Habitat. — We have no record of this species outside of Mexico. My two males were both collected at Orizaba, Mexico. B. diligens of Smith came from Oajaca, Mexico. While I have not been able to study this species, in com- parison with others, sufficiently to get a very certain idea of its relationships, it seems to me, from my somewhat super- ficial study, that crotchii and haueri are its closest allies. It is impossible to tell by the original description whether Smith's diligens was this species or the form to which Hand- lirsch gave the name dolichocephalus. Smith's type is prob- ably still in the British Museum. Col. C. T. Bingham TRANS. AM. ENT. SOC. , XXXIX. (19) 146 AMERICAN HYMENOPTEKA. wrote me that, while there are specimens labelled '^ Bomb us diligens'" in the collection of the British Museum, there are none bearing this name which are marked as type specimens, though most of Smith's types of Bomlms species can be readily identified by distinguishing marks. It is therefore possible that Smith's type of diligens cannot be identified, though still extant. If this is the case, brachycephahis must stand permanently as the name of this species, even if Smith described this species, and not dolichocephalus, as diligens.

Friese, Zeitsch. f. Systemat. Hym. und Dipt., IV Jahrg., Heft 3, May 1, 1904, p. 188, (f . I have not seen specimens of this species. The original description reads as follows : " Bombus ecuadorius nov. sp. — Black, pubescence of thorax black ; segments one and two yellow, the third covered with black pubescence, the fourth to sixth segments with white hair. Venter pale brown. Feet black, with black pubescence. Wings entirely tawny iridescent. Length 23 mm. Head a little elongate, the pubescence black. Clypeus shining, its sides strongly punctate. Labrum rounded, with numerous punctures larger than those on the clypeus. Mandibles rather slender, their bases considerably removed from the eyes. Thorax with black pubescence. Sides of mesothorax strongly punc- tate ; the disc shining, with punctures sparse. Scutellum sparsely punctate. Abdomen with the first and second segments yellow, the third black, the fourth, fifth and sixth white. The first segment not punctate, the second densely punctate, with gloomy aspect. The punctures of segments four, five and six are scattered and the surface is shining. Sixth dorsal segment concaved in the middle, cal- loused at the apex. Venter densely and deeply punctate. Sixth ven- tral segment without particular characters. Feet black, their pubescence black. Bases of the hind femora punc- tate, their apices very feebly and obliquely striated. Wings entirely tawny, with metallic reflections. Very rare and captured by missionary Boetzkeo at Quito, at an alti- tude of 2,000 meters above the level of the ocean." Friese's description of robtisius var. nigrothoracictis is as follows : HENRY J. FRANKLIN. 147 " Var. c?. — Thorax entirely black; segments one and two yellow-, three black-, four to six white-haired. Bolivia." I have here placed Friese's form in the synonymy of ecuadorius entirely on the basis of these two descriptions. In my opinion, this species is really a variety either of robushis, as Friese placed it, or of butteli. If it is really a variety of robiistus, then the name ecuadorius should be placed in the synonymy of that species. If, however, ecuadorms and btitteli are the same species, the name butteli (1903) must go into the synonymy of ecuadorius. If this species is a variety of robiistus or of butteli, it belongs to the subgenus Bombias. Ecuadorius may possibly, however, be a valid species by itself. Bonibus (Bonibias) sulfuratu.s Friese. Bonibus robustus var. su/furatus H. Friese, Deutsch Ent. Zeitschr., 1911, p. 457. Types. — The specimens from which Friese described this form came from Salta, Argentina (2,500 meters altitude), and are in his private collection. While this form is appar- ently closely related to robustus, I cannot agree with Friese in considering it a variety of that species, as the character of the pile seems to be noticeably different. Robustus has longer and finer and rather less dense pile than has this spe- cies. Friese has sent me a queen and a worker of this spe- cies, determined by him and collected in Argentina (Salta) by Steinbach, from which the following discription is made : Pile of medium letigth and texture. Malar space rather short. Thorax with mostly yellow pile, with black interalar band. Dorsum of abdomen with first three segments and base of fourth clothed with straw-yellow pile ; apical part of fourth segment rvith pale ferruginous pile ; fifth and sixth segmeftts ninstly while-haired. IFings rather light. Queen. Head. — Face above and below bases of antennae with very pale yellow and black pile mixed. Occiput with mostly black pile, but with some pale yellow admixed. Sides of head behind eyes mostly dark, but with a very noticeable admixture of pale yellow pile. Malar space about three-fourths as long as its width at apex, about one-fifth as long as eye. Clypeus, for most part, very sparsely punctate with moderate punctures. Ocelli large and placed distinctly below the supra-orbital line, almost exactly in the narrowest part of the vertex, the lateral ones distinctly nearer to the eye margins than to each TRANS. AM. ENT.

Thorax. — Dorsum clothed with straw-yellow pile, except for black band between bases of wings (this band well defined and without pile in middle). Mesopleura with mostly yellow pile from bases of wings to bases of legs. Metapleura with at least their upper portions bear- ing mostly yellow pile. Sides of median segment with mostly yellow pile. Abdomen. — Dorsum : segments one to three, inclusive, clothed with straw-yellow pile ; segment four with pale yellow pile on basal portion and with pale ferruginous pile on apical portion ; segment five with mostly white hair (the bases of the hairs, making up the pile on this segment, appear slightly ferruginous); segment six thinly clothed with mostly white pile. Venter with mostly dark pile, but the hairs fring- ing the apical margins of the middle and apical segments inclined to be pale in color towards the sides of the segments.

Legs. — Trochanters with mostly dark pile, but with at least a sprinkl- ing of pale hairs on their lower sides. Femora mostly dark, but with more or less pale hair on their lower sides, the two hind pairs in par- ticular having a noticeable amount of such pile. Tibiae with dark hair, including the corbicular fringes. Worker. — Like queen, but with fifth dorsal abdominal segment clothed with entirely ferruginous pile. Sides of head behind eyes with only a very slight admixture of pale yellow hairs. Dimensions. — Length : queen, 16 mm. ; worker, 13| mm. Spread of wings : queen, 37 mm. ; worker, 30 mm.

The species was originally described from tv^o workers and nine males, all from Costa Rica (San Carlos). The variety a /l>oca?cda fa was described from a single male from Bolivia. I have never seen a female of this species, and I seriously question whether the workers described by Friese did not in reality belong to the species montezumce, as his description answers perfectly for a color variation of that species. Friese HENRY J. FRANKLIN. 149 has sent me a male, from Colombia (San Antonio), deter- mined by him as weisi, and I am unable to connect it with any other species known to me. Queen. — Unknown. Worker. — Friese's description is as follows: " Black, black-haired ; like B. ephippiatus var. lateralis, but larger; segments 1-3 yellow-, 4-5 black-, 6 red-haired ; with longer cheeks. Length, 15 mm. ; width of thorax, 1\ mm." Male. — The single specimen before me, received from Friese, may be described as follows : Head. — Triangular in form. Face covered with a large and rather dense patch of nearly pure yellow pile, this patch extending from near the front margin of the clypeus to considerably above the bases of the antennae and from eye margin to eye margin. Occiput with a patch of mostly yellow pile in the middle, but with numerous black hairs intermixed. Sides of head behind eyes clothed for most part with bright yellow pile. Malar space but little more than half as long as its width at apex. Ocelli large and placed very slightly below narrowest part of vertex, at about one-third of the distance from the supra-orbital line toward the bases of the antennae, the lateral ones separated from the eye margins by about half their own diameter. Eyes considerably swollen, about like those of robustus male. Third and fifth antenna! segments subequal in length, the fourth shorter than either. Thorax. — Dorsum clothed for most part with yellow pile, but with a very poorly outlined dark band between bases of wings (this band being made up of a mixture of black and yellow pile, with the black predominating) ; middle portion with large naked area ; front portion of scutellum also naked in middle. Mesopleura covered with bright yellow pile from bases of wings to bases of legs. Metapleura and sides of median segment with mostly yellow pile. Abdomen. — Dorsum : segment one clothed with yellow pile ; segment two with mostly yellow pile, but with an inconspicuous amount of black hair on its apical middle ; segments three to seven, inclusive, with black pile. Venter with mostly dark brown or black pile. Wings. — Smoky, but not very dark. Legs. — Trochanters and femora of middle and hind pair of legs with considerable yellow pile, especially those of the hind pair; front femora with mostly black pile. Tibiae almost entirely dark. Hind tibiae with outer faces slightly convex and sparsely hairy, with front fringes moderate and hind ones long, forming weak corbicuhe. Hind metatarsi fully four times as long as their greatest width, their hind fringes long and dark brown in color. Dimensions. — Male: length, 17 mm. ; spread of wings, 37 mm. TRANS. AM. ENT. SOC. , XXXIX. 150 AMERICAN HYMENOPTERA. This species is probably closely related to robushis, though the ocelli are placed a trifle farther down from the supra- orbital line than is the case with the male of that species. Friese's descriptions of the male and of the n2X\q\.-^ albocau- data are as follows : " d^ with elongate antennae, very large eyes, yellow-haired face, thorax mostly yellow-haired, black banded, segments 1-2 yellow-, 3-7 black-haired, venter yellowish-haired.

Type. — Vachal writes me that this specimen is in his pri- vate collection and that, after his death, it will be deposited in the Museum Histoire Naturelle de Paris, to which it is already given by testament. This species is unknown to me. Vachal's original descrip- tion is as follows : " Bombus tecumanus n. sp. ? — Black, black-haired ; band on the col- lar, band on the scutellum, segments 1-2, with yellow pile ; clypeus, frons and vertex with admixture of yellow ; the very apex of the abdomen white.

Bingham succeeded in identifying Smith's type queen, for me, in the collection of the British Museum. It was collected in Colombia. The types of Friese's varieties are in his private collection. The worker type (Handlirsch description), also from Colombia, is in the collection of the k. k. Hofmuseum at Vienna. The typical male is here described for the first time — from three speci- mens, of which one is deposited in the collection of the Massachusetts Agricultural College and the other two in the collection of the United States National Museum. These males all came from Colombia. Pife rather long and rather fine. Malar space short in the male and rather short in the females. Ocelli of females distinctly below the supra- orbital line and very slightly above the narroivest part of the vertex ; those of the male considerably below the supra orbital line and in the nar- rowest part of the vertex, the lateral ones being separated by about half their own diameter frotn the eye margins. Eyes of male considerably TRANS. AM. ENT. SOC, XXXIX. 152 AMERICAN HYMENOPTERA. swollen. The coloration of the pile possibly quite variable., but the heads of the females and the pleura and legs of all castes dark and the apex of the abdomen almost always white above in all castes. Wings rather light. Typically : the dorsjim of the thorax yellow, with a black interalar band, arid the three basal dorsal abdominal segments yellow. Queen. Head. — Pile almost entirely dark, sometimes with an incon- spicuous admixture of very short tawny whitish hair with the longer dark hair on the occiput and on the face above and below the bases of the antennae. Malar space considerably shorter than its width at apex, nearly one-fifth as long as the eye. Clypeus, for most part, entirely smooth. Ocelli large and placed distinctly below the supra-orbital line, but slightly above the narrowest part of the vertex, the lateral ones much nearer to the margins of the eyes than to each other. Third antennal segment nearly as long as fourth and fifth taken together, the fifth longer than the fourth. Thorax. — Dorsum yellow, with a well defined black band between the bases of the wings (this band is apparently somewhat variable in width, being, in one of the specimens before me, very nearly half as long, from front margin to rear margin, as it is wide, from wing base to wing base, while, in the other specimen, it is not nearly half as long as wide); a naked area present on the middle of the disc. Mesopleura somtimes entirely dark and sometimes with the yellow pile on the front part of the dorsum extending down to somewhat below the level of the bases of the wings. Metapleura and sides of median segment entirely dark. No light or yellow tufts behind or beneath the bases of the wings. Abdomen. — Dorsum : segments one and two yellow ; segment three entirely yellow or with some black hair on the very hind margin, espe- cially toward the extreme sides ; segment four clothed entirely with white pile or mostly white with black pile on the very basal portion, especially the anterior corners ; segment five white ; segment six mostly dark in the middle, but with some white hair on the sides. Venter mostly dark, but with the sides of the apical margin of the fifth segment fringed more or less with whitish hair. Epipygium with a short and very broad and shallow longitudinal median impression toward the apex. Hypopygium without a distinct median carina. Wings. — Very light for a Bonibus queen ; only very moderately in- fuscate ; perhaps best described as light, almost transparent, brown. Legs. — All the pile, including the corbicular fringes, dark brown or black. Worker. — Like the queen, but with distinctly darker, rather strongly infuscate, wings. Clypeus with very sparse, but coarse, punctures. Male. Head. — Face bearing a mixture of dark and whitish or pale yellow pile above and below the bases of the antennae (most of the light pile is very much shorter than the dark hair of the mixture) . HENRY J. FRANKLIN. 153 Clypeus, for most part, densely covered with nearly pure pale yellow pile. Occiput mostly dark, but bearing a mixture of dark and yellow hairs in the middle. Behind the eyes dark. Ventro-lateral portions of head almost entirely dark, but with a slight admixture of yellow hairs almost opposite the lower ends of the eyes. Malar space but little more than half as long as its width at apex. Ocelli large and placed somewhat less than one-third of the distance toward the bases of the antennas from the supra-orbital line, exactly in the narrowest part of the vertex, the lateral ones being separated from the margins of the eyes bj' about half their own diameter. Eyes swollen so as to cause the vertex to appear distinctly depressed between them, about as in the male of separatus. (The antennae of all the males before me are lost.) Thorax. — Coloration of pile about like that of the queen and worker, but the black interalar band fully half as long, from front to rear, as wide, from wing base to wing base. Abdomen. — Dorsum : segments one, two and three entirely covered with yellow pile ; segment four dark, but with some of the hair on its hind margin tipped with white ; segments five, six and seven clothed with long, fine white pile (most of the hairs of this pile are dark brown or black at the base and shade out to white, so as to appear entirely white unless examined with a lens). Venter mostly dark. Apical margin of both epipygium and hypopygium entire. Genitalia. — Outer spatha in general form much like that of rtifo- cinctus (fig. 122), but much longer {i. e., with a much greater dis- tance between the front and hind margins); the hair on the ventral surface of the apical portion sparse and short, being thickest and most conspicuous on the hind corners. Inner spatha appearing much like that of rufocinctus (fig. 55), but with a conspicuous rounded-triangu- lar fenestra on each side of the middle of the front part of the apical portion. Claspers (figs. 181 and 197) long, but apparently powerful ; branches broadly rounded at apex as seen from dorsal side ; squamae strongly bilobed, the outer lobe being much the larger, triangular in shape and with evenly curved inner and outer margins and pointed apex, and the inner lobe being rounded at the apex and extending mesad but slightly beyond the inner margin of the volsella. Volsella; only very moderately hairy ; considerably widened in the middle by a broadly rounded protuberance on the inner side of each ; their apical projections not very large, but conspicuous and with serrate inner margins. Sagittae with long and nearly straight shafts and recurved heads ; the heads considerably foliaceous and projecting mesad in a somewhat sickle-shaped foliaceous extension ; considerably outreached by the apices of the volsellae. Uncus quite broad at base, but taper- ing gradually to the moderately wide, rounded and recurved tip. ^?«^.J.— Somewhat darker than those of the queen, but somewhat lighter than those of the worker.

The queen is here redescribed from two specimens and the worker from one. Habitat. — We have certainly valid records for this species from Colombia, Venezuela and northern Argentina (Tucu- man and Salta) only. There are specimens before me from Colombia and Venezuela. Cameron records it from Ecuador (Pichincha), at an altitude of 11,500 feet. It is almost cer- tainly present in Peru, Bolivia and northern Chili. The species probably has a considerably wider range than is in- dicated by these records. Variation. — Friese has described the following forms as varieties of this species : "1. Var. S. Segments one and two yellow-, three black-, four red-, five and six white-haired. Bolivia. Var. cinctus.'' Friese has sent me an identified specimen of this form, and he is apparently correct in regarding it as a variety of robustus. The fourth dorsal segment, however, is not red, but yellow, in the specimen sent me. This speci- men came from Bolivia. " 2. Var. c? 9 S . Segments 1-3 black-, 4-6 white-haired. 9 usu- ally with yellow tufts of hair on segment three. Banos (Ecuador). Var. hortulatis .'' ^ Friese has sent me a worker and male of this form, and I agree with him in considering it a variant of robustus. "3. Var. cf. Thorax entirely black ; segments one and two yellow-, three black-, four to six white-haired. Bolivia. Ya.r. nigrothoracicus.'' This form is unknown to me, as are also the two following : "4.

FRANKLIN. 155 The form horhdans indicates a marked variation, on the part of robzistus, toward volucelloides, with which it is closely allied. Nigrothoraciais appears to belong in the synonymy of ecuadorius, but eaiadorius may, in reality, be a variety of robusttis. If ecuadorius is a variety of robiistus, it gives addi- tional evidence that robiishis grades strongly toward vohi- celloides. Ridocaiidatus may be a variety of robustus, but, because of its color characters, I suspect it of having affinities with opifex. Steinbachi is probably a valid variety of robustus. Volucelloides is, beyond question, the closest relative of robustus, and it may, indeed, be only a subspecies of it. The yellow pile of this species varies in shade from deep straw- yellow to very pale straw color. Bouibus (Bombias) volucelloides Grib. Bojubus volucelloides Gribodo, Bull. Soc. Ent.

Ocelli of queen and worker placed almost exactly in the narrowest part of the vertex. Legs black. Wings very dark Queen. Head. — Rather broad and rounded. Pile all dark. Malar space shorter than its width at apex, but little more than one-sixth as long as the eye. Clypeus very delicately punctate and shining. Ocelli large and placed considerably below the supra-orbital line, just TRANS. AM. ENT. SOC, XXXIX. 156 AMERICAN HYMENOPTERA. about in the narrowest part of the vertex. Third antennal segment much longer than the fifth, not greatly shorter than the fourth and fifth together; the fifth somewhat longer than the fourth. Thorax. — Dorsum covered with dark cinereous pile (this pile is a mixture of black hairs and mostly shorter and finer white pile or down); a considerable area on the center of the disc naked. Pleura and sides of median segment entirely dark. Addume ft. —Dorsum: segment one black; segment two black, but with apical margin bearing white hair. Segments three, four and five covered with white pile ; segment six dark in the middle, but with white hair on the sides. Venter mostly dark, but with fringes of apical margins of most of the apical segments more or less white or whitish. Epipygium with a very slight longitudinal median carina on very apical portion. Hypopygium without a median carina. JVings.— Very dark. With strong violaceous reflections. The trans- verse median vein of the fore wings forming nearly a right angle with both the median and the anal vein. Le^s.— Pile entirely dark. JVorker.— Like the queen, but the clypeus rather more coarsely punctate. Ma/e. — Unknown. Dimensions.— Length : queen, 20 mm. to 26 mm. ; worker, 13 mm. to 15 mm. Spread of wings: queen, 46 mm. to 50 mm.; worker, about 34 mm. The typical queen is here described from two specimens from Boquete, Chiriqui. There are specimens before me showing the following variations : Color Variant i.— Like the typical queen, but with no white hair on the apical margin of the second dorsal abdominal segment. One speci- men, from Boquete, Chiriqui. Color Variant 2. — Like the typical queen, but with the second dor- sal abdominal segment entirely black and with the basal portion of the third segment clothed with black pile. One specimen, from Colombia. Color Variant J.— Like Color Variant 2, but with the third dorsal abdominal segment entirely black, except the very apical margin. One queen from Chiriqui and one from Ecuador. Color Variant 4. — {= vogti H. Friese). Like Color Variant 3, but with the third dorsal abdominal segment entirely black and with the basal half of the fourth segment also covered with black pile. One queen, from Bolivia (Tarata). Color Variant 5 . — Like the typical worker, but with all but the last two dorsal abdominal segments covered with entirely black pile. One worker, from Bolivia (Tarata). Color Variant 6.— Like Color Variant 3, but with the short, fine pile HENRY J. FRANKLIN. 157 on the dorsal disc all dark, thus making the pile as a whole on this region black instead of dark cinereous. Color Variant 7. — Like typical worker, but with the second, third and fourth dorsal abdominal segments entirely black and the fifth seg- ment also dark, except for a fringe of white hair on the basal margin and on the extreme sides ; the sixth segment almost entirely dark, with only a few white hairs on the extreme sides ; venter entirely dark. One specimen, from Peru (Chanchamayo). Habitat. — The following are our valid records for this spe- cies: Chiriqui (Boquete), Costa Rica (Cartago, Zarzero, Volcano Irazu, Monte Redonda), Colombia (Popayan), Ecuador, Peru (Chanchamayo, Callanga and Marcapata) and Bolivia (Tarata). This species is most closely related to rohisius. The pile of this species is somewhat longer and finer than the average. A queen and worker of vogti, determined and labelled by Friese, are before me, and there can be no doubt that vogti belongs with volucelloides. Mr. J. C. Crawford has written me that the name " Bonibus vohicel hides'' was omitted by mistake when page 157 of volume xxxii, 1906, of the Transactions of the American Entomological Society was printed. This name should have appeared at the beginning of the third line from the bottom of the page. Boinbiis (Bonil)ias) funebris F. Sm. Bonibus funebris Smith, Cat. Hym. Brit.

SOC, XXXIX. 158 AMERICAN HYMENOPTERA. former and three of the latter, one of each being deposited in the collection of the Massachusetts Agricultural College and the rest in the collection of the United States National Museum. The worker cotypes were collected at Callanga, Peru, and the males in Ecuador. Black and with entirely black pile, except the disc of the thorax and the apical portion of the abdomen above clothed ivith white pile Wings rather light. Qtieen. Head. — Clothed entirely with dark brown or black pile. Malar space shorter than its width at apex, between one-fifth and one- sixth as long as eye. Clypeus, for most part, sparsely, but rather coarsely, punctate ; densely punctate on sides of very front part. Ocelli somewhat below supra-orbital line, but distinctly above nar- rowest part of vertex, the lateral ones somewhat nearer to the margins of the eyes than to each other. Third antennal segment nearly as long as the fourth and fifth taken together; the fifth somewhat longer than the fourth. Thorax. — Disc of dorsum clothed with white pile ; otherwise entirely dark brown or black. Abdoinen . — Dorsum : segments one and two entirely black ; segment three black, but sometimes with some white hairs on its apical middle; segments four and five clothed entirely with white pile ; segment six mostly dark, but with white pile on the extreme sides. Venter mostly dark. Neither the epipygium nor the hypopygium with a carina. Wings. — Only very moderately infuscate, light for a Bonibus queen. The transverse median vein of the fore pair coalescent at the base, for a very short distance, with the base of the discoidal and bent so as to form a slightly obtuse inner angle with both the median and the anal vein. Legs. — Clothed with entirely dark pile. Hind margins of hind meta- tarsi unusually arcuate, about as in the Terrestris group. Worker. — Like queen, but with no white hair on third abdominal segment and with pile on very base of fourth segment black. Male. Head. — Triangular. Pile all dark brown or black. Malar space about two-thirds as long as its width at apex. Clypeus, for most part, rather heavily clothed with pile. Ocelli placed at about one-fifth the distance from the supra-orbital line toward the bases of the antennae, slightly above the narrowest part of the vertex ; the lateral ones separated by about their own diameter from the margins of the eyes. Eyes somewhat swollen, about like those of male ru/o- cinctus. Third and fifth antennal segments subequal in length, the fourth shorter than either. Thorax. — Coloration of pile about like that of queen and worker. Abdomen. — Dorsum : segments one, two and three dark ; segment HENRY J. FRANKLIN. 159 four mostly dark, but with white pile on apical margin ; segments five, six and seven clothed with white pile (sometimes many of the hairs of this pile are black at the base and shade out quickly into white). Venter usually mostly dark, but with some of the hair on some of the apical segments whitish. Hypopygium entire at apex. Genitalia — Outer spatha (fig. 153) short and wide ; its front margin deeply and evenly incurved, the side margins evenly, but not strongly, outcurved, the hind margin deeply and evenly incurved ; ventral sur- face of hind portion rather sparsely hairy with long hairs. Inner spatha in general form much like that of crotchii (fig. 130), but with- out fenestrae and with hind margin of apical portion more deeply emarginate. Claspers (figs. 178 and 180) powerful in appearance ; branches with apices appearing rather quadrate with rounded cor- ners as seen dorsally ; volsellse moderately thick and tapering some- what, so as to be narrowest at distal end, their apical projections small, but noticeable; squama with two well developed lobes, the outer one being the larger and having its outer face deeply concaved and strongly roughened by protuberances and striations. Sagittae with long shafts and recurved, broadly foliaceous heads, the outer margins of these heads being serrated. Head of sagitta extending back fully as far as tip of squama and tip of volsella not extending very far beyond either the sagitta or the squama. Uncus broad and tapering slowly toward the recurved and mesially grooved tip. Inner end of inner lobe of squama reaching but little beyond inner margin of volsella. Wings. — Colored about like those of queen. Legs. — Mostly dark. Hind tibias with outer faces convex and more or less hairy throughout (sometimes with only a very few scattering hairs on the apical half), their fore fringes moderately long and their hind ones very long, forming fairly good corbiculae. Hind metatarsi more than three times as long as their greatest width, with outer faces flat or nearly so and hind fringes long. Dimensions. — Length: queen, about 17 mm.; worker, 12 mm. to 13 mm. ; male, 12 mm. to 14 mm. Spread of wings : queen, about 40 mm. ; worker, 27 mm. to 30 mm. ; male, 31 mm. to 33 mm. The queen is here redescribed from two specimens. There is a worker from Costa Rica before me which ap- parently belongs to this species, though in coloration of pile and color of wings it is more like vohicelloides. It does not agree with vohicelloides in structure, but it does agree with funebris. It may be described as follows : Color Variant i . — Like typical worker, but with white patch on disc of thorax obliterated, except for a noticeable trace in front, and with apical two-thirds of third dorsal abdominal segment clothed with white TRANS. AM. ENT. SOC, XXXIX. 160 AMERICAN HYMENOPTERA. pile. With some white hairs on middle of basal margin of second seg- ment. Wings strongly infuscate, distinctly darker than those of typi- cal worker and with distinct violaceous reflections. Habitat. — Bolivia (Tarata), Peru (Callanga), Ecuador (Quito, Machachi— 10,000 feet, Hac. Guachala— 9,217 feet, Pichincha— 11,500 feet, Chillo— 9,000 feet, S. Lucia— 8,000 feet, Hac. S. Rosario — 10,300 feet), Colombia and Costa Rica (no typical specimen from Costa Rica). This species does not appear to have any very close allies. One might think from its color that its nearest relative was volticelloides, but it is structurally most like hitteli and baeri. This structural likeness is seen particularly in the position of the ocelli relative to the eye margins and the supra-orbital line. The dark pile on the head, pleura, legs, abdomen and sides of median segment of the males is nearly all tipped some- what with pale color so as to appear somewhat cinereous. The pile of the species, as a whole, is fine and of somewhat more than medium length. A queen, worker and male determined by Friese are before me. Bombus (Bombias) liaiidlirschi Friese.

Types. — Friese described this species from two queens, seven workers and three males. The workers and males came from Marcapata, Peru, through Staudinger, and are now in Friese's private collection as, he writes me, are also the types of all his other Neotropical species. The two queen cotypes are in the collection of the Berlin Museum and it is quite possible that they cannot be identified with certainty, as Friese, when he published the descriptions of the worker and male, appears to have described the queen inadvertently from memory. Pile long and rather fi7ie. Pile on head and on dorsutn of thorax dark ashen gray. Pleura ferruginous. Dorsum of abdomen ferrugin- ous at base and apex, but dark fuliginous in middle. Legs and venter of abdomen mostly ferruginous. HENRY J. FRANKLIN. 161 Queen. — This caste is unknown to me. Friese states that in colora- tion it is like the worker, but that it is "nearly the size of dahlboinii,^^ reaching a length of 26 mm. Worker. Head. — Of medium length. Pile on face and occiput very dark cinereous. Pile on sides of head behind eyes mostly very dark cinereous, but rather strongly ferruginous underneath toward bases of mandibles. Malar space fully as long as its width at apex, very nearly one-fourth as long as eye. Clypeus smooth and shining, rather sparsely and, for most part, very delicately punctate. Ocelli practically on supra-orbital line, above narrowest part of vertex. Third antennal segment longer than fifth, the fifth longer than the fourth. Thorax. — Dorsum covered entirely with dark ashen gray pile. Meso- pleura from level of bases of wings to bases of legs covered with fer- ruginous pile. Metapleura and sides of median segment also clothed with ferruginous hair. Abdomen. — Dorsum: segment one ferruginous; segments two and three dark fuliginous, but with considerable ferruginous pile on the extreme sides and also with that color sometimes mixed in somewhat with the fuliginous in the middle ; segments four and five ferruginous; segment six mostly dark, but fringed with short ferruginous hair. Venter with mostly pale ferruginous pile. Neither epipygium nor hypopygium carinate. IVings. — Very strongly infuscate, dark for a Bombiis worker ; the fore pair with a slight violaceous reflection. Transverse median vein of fore wings usually nearly straight (not curved noticeably, as in most species of the subgenus Bombiis) and not coalescing at base with base of discoidal, yet forming an obtuse inner angle with the me- dian vein (but this angle is less obtuse than is usual in the subgenus Bombus) . Legs. — Coxae, trochanters, femora and tibiae all clothed almost en- tirely with ferruginous hair, except the anterior tibiae often mostly dark on their front sides ; corbicular fringes entirely ferruginous. Apices of hind metatarsi not drawn out into a very prominent pro- jection behind the insertion of the second tarsal segment. Male. — Unknown to me. Friese described this sex as follows : "male like worker, but with larger eyes; clypeus porrect. Length, 18-19 mm." Dimensions . — Length : queen, 26 mm. ; worker, 12 mm. to 15 mm. ; male, 18 mm. to 19 mm. Spread of wings of worker, 28 mm. to 31 mm. The worker is here redescribed from four specimens — three of them being the same three described by me in Ento- mological News, XVIII. Habitat. — Peru (Marcapata and Callanga) and Ecuador. TRANS. AM. ENT. SOC. , XXXIX. (21) 162 AMERICAN HYMENOPTERA. Three of the workers before me are from Callanga and one is from Ecuador. The veination of the fore wings and the formation of the apex of the hind metatarsi of the workers lead me to place this species in the subgenus Bombias and Friese's descrip- tion of the male—" as worker, but with larger eyes " — makes me confident that I am right in doing this. The ocelli of the worker are, however, placed as in the subgenus Bomhis. Its closest ally is evidently rubicundus, from which it can be readily separated by marked differences in the coloration of its pile. The species was named for Herr Anton Handlirsch, a bee student of Vienna. Friese has sent me a worker of this species, from Ecuador, in good condition and determined by him.

Bingham found Smith's type specimen in the collection of the British Museum for me. It came from Colombia. Friese's workers came from Ecuador (Cuenca, 2200 meters altitude) and Mexico (Colon). The male is here described from two specimens (from Colombia), the cotypes of that sex, deposited in the collection of the United States National Museum and the collection of the Massachusetts Agricultural College. Malar space short. Pile fine and rather long. Thorax efitirely rufo- ferruginous. Head of queen with rufo ferruginous pile ; of worker and male mostly dark. Dorsum of abdomen of queen either entirely rufo- ferruginous or partly rufo-ferruginous and partly dark fuliginous ; of worker and male partly rufo ferruginous and partly dark fuliginous ; of worker sometitnes mostly black. Corbicular fringes black. Queen. Head. — Broad and rounded in form. Face, occiput and sides usually bearing little but rufo-ferruginous pile ; sometimes with a strong admixture of black hairs with the red, especially on the sides HENRY J. FRANKLIN. 163 and on the occiput. Malar space much shorter than its width at apex, nearly one-seventh as long as eye. Clypeus rather coarsely and densely punctate, largely clothed with reddish pile. Ocelli rather large, placed somewhat below supra-orbital line and slightly above nar- rowest part of vertex, the lateral ones somewhat nearer to the mar- gins of the eyes than to each other (transitional Bombias in this respect). Third antennal segment longer than fifth, the fifth longer than the fourth. Thorax. — Clothing of dorsum, mesopleura, metapleura and sides of median segment all rufo-ferruginous. Abdomen. — Dorsum: segment one entirely rufo-ferruginous; seg- ments two and three usually entirely rufo-ferruginous, but sometimes darkened considerably by a strong admixture of black hairs ; segment four entirely rufo-ferruginous ; segment five usually entirely rufo- ferruginous, but sometimes with considerable dark fuliginous pile on sides ; segment six sometimes rather strongly rufo-ferruginous, but usually mostly dark fuliginous or black. Venter dark, its pile some- times mostly reddish and sometimes mostly dark. Hypopygium with- out a median carina. Wings. — Only moderately dark, with very slight violaceous reflec- tions. Legs. — Coxae, trochanters and femora all with much rufo-ferrugin- ous pile, at least on their lower sides. Tibia, including the corbicular fringes, all black. Metatarsi with no long fringes. Worker. Head. — Face bearing a mixture of ferruginous and black pile, the former being predominant. Occiput with a strong admixture of ferruginous pile with the black. Ventro-lateral sides of head dark, with ferruginous pile admixed and rather predominant. Structural characters as in queen, but with ocelli practically on supra-orbital line. Thorax. — Coloration of pile like that of queen. Abdomen. — Dorsum : segment one rufo-ferruginous ; segments two and three with pile appearing mostly dark fuliginous (the basal por- tions of the hairs that make up this pile are really rufo-ferruginous while their apical portions are very dark brown); segment four mostly rufo-ferruginous ; segments five and six mostly dark, but with consi- derable cinereous hair. Venter dark, with the apical fringes of the segments mostly rufo-fuliginous. Whigs. — Slightly lighter than those of queen. Legs. — Much as in queen, but the femora as a rule with less reddish pile, being mostly dark except the lower sides of their basal portions. Male. Head. — Face bearing a mixture of tawny and dark brown pile, that covering the greater part of the clypeus being almost entirely tawny. Occiput and sides of head entirely dark brown or with an ad- mixture of tawny pile. Malar space about half as long as its width at apex. Third antennal segment somewhat longer than fifth, the fourth TRANS. AM. ENT. SOC, XXXIX. 164 AMERICAN HYMENOPTERA. shorter than either. Ocelli placed in narrowest part of vertex, at less than one-third of the distance from the supra-orbital line toward the bases of the antennae, the lateral ones being separated from the mar- gins of the eyes by about their own diameters. Eyes noticeably, but not greatly, swollen. Thorax. — Coloration of pile as in queen and worker. Abdomen. — Dorsum : segment one rufo-ferruginous ; segments two and three with mostly black pile, but with a considerable admixture of rufo-ferruginous hair on their middle portions (all but the extreme sides have some reddish hairs admixed); segments four and five mostly rufo-ferruginous, but with some black pile on their extreme sides ; segments six and seven mostly dark, but with more or less red- dish or cinereous hair toward their sides. Venter mostly dark, but with the apical fringes of most of the segments long and mostly pale reddish or whitish in color. Hypopygium distinctly emarginate at apex. Genitalia. — Outer spatha (fig. 152) very short and wide, the front margin being deeply incurved and the side margins rather irregularly outcurved ; apical portion with an angular projection on each side, the margin between these projections being somewhat incurved ; each side of the hind portion with a broad reticulated area. Inner spatha much like that of separatiis (fig. 127), but with front margin of ante- rior median projection more thickly chitinized. Claspers (figs. 186 and 195) long and not very stout, the branches, as seen from dorsal side, appearing strongly quadrate at apex. Volsellae without noticeable pro- jections on their inner sides, except the prominent, square-ended, elon- gate, and rather narrow apical projections ; with a large amount of hair present on nearly all portions, as seen from ventral side, this hair being very noticeably long on the outer sides of their apical portions. Squama very strongly bilobed, both lobes being unusually long and slender ; the outer lobe enlarged somewhat in its apical portion and with a noticeable tooth-like projection on the outer side of this portion, but with its very apex pointed ; the inner lobe elongate-triangular in form, with its round-pointed apex reaching mesad far beyond the inner margin of the volsella. Sagittae with very long shafts, the heads reach- ing slightly beyond the apices of the volsellae and having a prominent, though slender, tooth-like projection on the inner side of each, their rather narrow apices being recurved ventrad somewhat. Uncus long and only moderately broad even toward the base. Wings. — Usually somewhat lighter than those of worker; light brown, with outer portions almost transparent. Legs. — Coxae, trochanters, and at least the basal portions of the femora largely clothed with cinereous or ferruginous hair (at least on their lower sides). Tibiae all dark. Outer faces of hind tibiffi slightly convex and almost completely naked, the fringes on apical third being HENRY J. FRANKLIN. 165 rather long and forming distinct, though weak, corbiculae. Hind metatarsi about three times as long as their greatest width. Diviensions. — Length: queen, 17 mm. to 19 mm. ; worker, 11 mm. to 13 mm. ; male, 13 mm. to 15 mm. Spread of wings : queen, 41 mm. to 46 mm. ; worker, 28 mm. to 31 ram. ; male, about 32 mm. Width of abdomen at second segment : queen, 9 mm. to 10 mm. ; worker, 6 mm. to 7 mm. ; male, nearly 7 mm. The queen is here redescribed from four specimens and the worker from two. Variatio7i. — Two workers (from Venezuela) before me, evidently belonging to this species, differ considerably from the typical worker in the coloration of the abdomen. These workers may be described as the following : Color Variant. —Like typical worker, but with dorsum of abdomen all dark fuliginous, except the rufo-ferruginous pile on the anterior angles of the first segment and a considerable patch of the same color on the fourth segment ; dorsum of thorax also with a noticeable ad- mixture of very dark brown hairs, mostly between bases of wings and in front ; occiput and sides of head dark fuliginous, without an ad- mixture of ferruginous pile ; face with a mixture of dark and ferrugin- ous pile, neither color being noticeably predominant. There is also before me a male received from H. F'riese and labelled by him " Bombjcs bicolor,^' which varies some- what from the typical male above described. This specimen may be described as follows : Male Color Variant 1. — Like typical male above described, but with dorsum of thorax, between bases of wings, strongly shaded with dark pile (this dark pile being intermixed with the rufo-ferruginous pile) and with dorsum of abdomen bearing pile as follows : Segment one dark, except for some ferruginous pile admixed on anterior corners ; segments two and three entirely black ; segment four rufo-ferruginous in middle, but black on extreme sides ; segment five black on extreme sides and in very middle, but otherwise covered with rufo-ferruginous pile; segment six almost entirely black, but with a faint sprinkling of whitish hairs on extreme sides ; segment seven cinereous. The speci- men was collected in Peru (Callanga). Habitat. — We have the following valid records : Colombia, Mexico (Colon), Venezuela, Ecuador (Cuenca, about 7,000 feet altitude) and Peru. Some of the queens before me are from Colombia and some from Venezuela and the typical workers before me are from Colombia. This is a handsome TRANS. AM. ENT. SOC. , XXXIX. 166 AMERICAN HYMENOPTERA. species and it resembles dahlbomii considerably in colora- tion, but the pile is of a darker, deeper red than in that spe- cies. Ricbiaindus seems to have no very close relatives among the known forms of the New World, except hand- lirschi. Bonibus (Bombias) baeri Vachal. ? Bombus bicoloratus Smith, Descr. New Spec.

Types. — Vachal's specimens (two 5 's and one d^ ) are in his private collection and are given, by his testament, to the Mu- seum of Natural History of Paris. Smith's type of bicolora- tus may probably be identified in the collection of the British Museum. Vachal's specimens came from Argentina (Lara). The queen is here described for the first time, from seven cotypes of that caste from Puno, Peru, deposited in the col- lection of the Museum of Comparative Zoology at Cam- bridge. Malar space rather short. Female ocelli placed sovieivhat, but not far, below the supra-orbital line. Clothiyig of head and thorax dark. Dorsum of abdomen entirely covered with bright coppery red pile. Legs black. Wings rather light. Quee7i. Head.— With, only black pile on face, occiput and sides. Malar space about as long as its width at apex, about one-fifth as long as eye. Clypeus jrather strongly and evenly punctate. Ocelli rather large and placed somewhat below supra-orbital line, nearly in narrow- est part of vertex ; the lateral ones but slightly nearer to the margins of the eyes than to each other (transitional Bombias in this respect) . Third antennal segment longer than fifth and fifth longer than fourth. Thorax.— PWe black, but in some cases with a very slight coppery reflection in certain lights. Abdomen.— Dorsum clothed entirely with bright coppery red pile, somewhat lighter toward apex. Venter mostly dark, but with a slight sprinkling, especially on lateral portions of apical margins of apical segments, of reddish hairs. Hypopygium without median carina. Wings. — Light colored for Bombus queen ; the basal two-thirds of the fore pair somewhat infuscate, the outer third being nearly clear transparent. Legs. — Coxae, trochanters, femora and tibiae with black pile only. Worker and Male. — These castes are unknown to me. The original description of them is as follows : HENRY J. FRANKLIN. 167 " Black, dorsum of abdomen red, the rest of the body black-haired. Head short, malar space scarcely longer than the width of the man- dibles. S . Third antennal segment longer than the fourth and than the fifth ; apex of hind metatarsi sinuate in the middle, not spinose on the angles. cf . Facies pauIo latior, oculis tumidulis, antennarum articulo 3 includentibus simul sumptis fere longiore ; tibia 3 sat concava lucida ; tibiae 3 et prototarsi 3 jugo supero longe ciliato. Length of w irker, 12-13 mm.; wing, 11 mm. Length of male, 14-15 mm. ; wing, 12.5 mm." I have not here translated the description of the male from the Latin as this description does not seem to be clear in all respects. The queens from which the description given above was made varied in length from 17 mm. to 21 mm. Habitat. — Argentina (Lara — 4,000 meters altitude), Boli- via (Tarata) and Peru (Puno). Probably also present in the northern portion of Chile. Cocci7ietis may be related to this species. Smith's bicoloratus may have come from South America instead of from Asia. Apparently bicoloratus was described from a specimen in a mixed collection of South American and Asiatic specimens, as the description was given in a paper which gave the original descriptions of species from both of those continents. The Asiatic habitat of two {bicoloratjis 2ind. bellicostis) of the seven supposedly Asiatic species of Bombiis, published by Smith in " Descriptions of New Species of Hymenoptera in the Collection of the British Museum (1879)," is now ques- tioned because of the striking similarity of their descriptions to two strikingly and peculiarly colored South American species {baeri and thoracicus). A careful examination of the habitat of bicoloratus and bellicos7is, as given by Smith, leads to interesting speculation. He gave the habitat " Sumatra or India" for bellicosus. The fact that he did not say defi- nitely either Sumatra or India shows conclusively that his specimen had no locality label and that he depended either upon memory or hearsay, either one an unreliable factor in TRANS. AM. ENT. SOC, XXXIX. 168 AMERICAN HYMENOPTERA. scientific work, for his information concerning the habitat of the species. From this, we can safely say that probably Smith merely had the impression that bellicos^is came from either Sumatra or India. He evidently had no certain knowl- edge concerning its habitat. For bicoloratus he gives the habitat " Island of Formosa." This seems definite and may be correct. Apparently, in this case, the specimen was labelled. Definite information con- cerning the exact wording of that label would be interesting. Did it really read " Island of Formosa," or did it read simply " Formosa," Smith's opinion or imagination having supplied the remainder of his published habitat ? If the label bore only the word " Formosa," it might have meant Formosa (Formosa Territory), Argentina instead of the Island of Formosa. It seems quite possible that specimens of baeri bearing the label " Formosa " and specimens of thoracicus without label, these two species coming as they do from the same general portion of South America, were added to the British Museum collection at about the same time (possibly also with specimens of other South American species — all perhaps having been collected by the same expedition or the same individual) and were, when in this condition, mixed up with a collection of bumble-bees from Asia, and that Smith relied largely either upon his own memory or upon that of someone else in publishing the habitat of these spe- cies as he did. It should be noted in this connection, however, that Prof. T. D. A. Cockerell has recently recorded (" Bees in the Col- lection of the United States National Museum " — Proceed- ings United States National Museum, Vol. 39, page 642, March, 1911) Bombus bicoloratus from Horisha, Formosa (collected by T.

Types. — Friese described this species from two workers which are still in his private collection. One of these speci- HENRY J. FRANKLIN. 169 mens came from Peru (Marcapata) and the other from Ecua- dor. The species was named for Dr. H. v. Buttel-Reepen. Pile rather long and fine. Malar space rather short. Head and thorax ivith dark cinereous pile. Dorsum of abdomen ferruginous at base, dark in middle and mostly white at apex. IVittgs rather light. Legs mostly black. Queen . — Unknown . Worker. Head. — Pile on face, occiput and sides behind eyes all dark cinereous. Malar space distinctly shorter than its width at apex, about one-sixth as long as eye. Clypeus sparsely, but rather coarsely, punctate. Ocelli almost touching supra-orbital line ; the lateral ones distinctly nearer to the margins of the eyes than to each other. Third antennal segment longer than fifth, the fifth longer than the fourth. Thorax. — Dorsum, pleura and even the sides of the median seg- ment clothed with dark cinereous pile ; the very center of the disc naked, smooth and shining. Abdomen. — Dorsum : segments one and two clothed entirely with ferruginous pile ; segment three with its basal portion clothed with »ntirely ferruginous pile and its apical portion mostly black with a slight admixture of ferruginous hairs; segment four mostly black, but with its apical margin fringed with white hairs ; segment five thinly clothed with white pile ; segment six dark in middle, but thinly clothed with white pile on extreme sides. Venter mostly dark, but with the apical fringes of some of the apical segments tending to be pale. Neither epipygium nor hypopygium with median carina. Wings. — Only moderately infuscate ; the fore pair slightly lightest across their middle portions. Transverse median vein of fore wings coalescent at base for a short distance with the base of the discoidal, but, aside from this, as in Bombus. Legs. — The fore coxae, trochanters and femora, and the middle and hind coxae and trochanters and the lower sides of the very bases of the middle and hind femora largely clothed with more or less cinereous pile ; the middle and hind femora and all the tibiae with mostly dark brown or black clothing. Male. — Unknown. Dimensions .—'Length, about 12 mm. ; spread of wings, about 27 mm. ; width of abdomen at second segment, about 6 mm. One of the specimens before me is from Bolivia (Bella Vista — Yungas), and the other two, received from Friese and determined by him, are from northern Peru (Huancab- amba — 9,700 feet altitude). Possibly this species is only a variety or subspecies of ecuadorhis. The cinereous pile of the head and thorax is TRANS. AM. ENT. SOC. , XXXIX. (22) 170 AMERICAN HYMENOPTERA. a mixture of rather long dark brown or black hairs and much shorter and finer and much more branched white or whitish pubescence or down. The ferruginous pile is perhaps better described as golden-russet in color. This species is ex- tremely transitional in its Bombias characters, as those char- acters were originally described, but the venation of the fore wings appears to establish its position in this subgenus. The venation of the hind wings is, however, as in the sub- genus Bombtis. One of the specimens before me (from Huancabamba, Peru) has the third dorsal abdominal segment clothed en- tirely with ferruginous pile and should therefore be con- sidered a color variant.

Types. — Friese described this species from three workers and five males, all from Marcapata, Peru. These specimens are in his private collection. Malar space medium. Pile of medijim length and rather fine. Head and thorax black. Dorsum of abdomen with first segment black, mid- dle segments red and apical segme^its white or whitish haired. Venter mostly dark. Legs black. JVings rather light. Queen. — Unknown. Worker. Head. — Pile entirely dark brown or black. Malar space but little shorter than its width at apex, nearly one-fourth as long as eye. Clypeus moderately punctate. Ocelli placed distinctly above narrowest part of vertex and but little below supra-orbital line, the lateral ones being placed about as far from each other as from the eye margins. Third antennal segment longer than fourth. Thorax.— V\\& all black. An area on middle of dorsum of thorax and a smaller one on front part of scutellum naked of pile.

Venter with mostly dark brown or black pile, but with some whitish hairs on last segment. Wings. — Light, but somewhat smoky. HENRY J. FRANKLIN. 171 Legs. — Coxae, trochanters, femora and tibiae clothed with dark brown or black pile. Male. Head. — With black pile only. Malar space very nearly as long as its width at apex, about one-fifth as long as eye (longer than that of any other Bonibias male known to me) . Clypeus largely naked, or sparsely pilose, and moderately coarsely punctate. Ocelli placed distinctl}^ below supra-orbital line and very slightly above narrowest part of vertex ; lateral ones distinctly nearer to margins of eyes than to each other, but separated from eyes by distinctly more than their own diameters. Eyes only very slightly swollen (less so than the eyes of any other Bombias male known to me) . Third antennal segment longer than fifth ; the fifth longer than the fourth. Thorax — Pile all black. An area on front part of middle of scutel- lum naked and another area on center of dorsal disc naked and mostly smooth. Abdomen. — Dorsum : segment one black, but with a slight admix- ture of coccineo-ferruginous pile on extreme sides. Segment two mostly coccineo-ferruginous, but with black pile in middle ; segments three and four covered with entirely coccineo-ferruginous pile ; seg- ment five mostly coccineo-ferruginous, but with a mixture of white and black hair on apical middle ; segment six with some short black hairs in middle, but clothed for most part with white pile ; segment seven with mostly white pile. Venter mostly black, but with apical margin of apical segment bearing a heavy fringe of short ferruginous pile. Genitalia. — Outer spatha (fig. 155) very short and broad, with a large reticulated area on each side of the posterior portion of the ven- tral surface, these areas being united by reticulations running along the hind border ; the front margin deeply incurved ; the side margins curved inward in front and outward behind ; the hind margin deeply incurved in the middle. Inner spatha much like that of fervidus (fig. 101), but with anterior median projection much more prominent than in that species and with hind margin of apical portion somewhat out- curved. Claspers (figs. 185 and 191) long and apparently thick and powerful ; the branches, as seen from dorsal side, with moderately wide and broadly rounded apices, the ventral side of each branch hav- ing a single very noticeable branched hair rising from the bottom of a rather deep pit, this pit being located opposite the base of the vol- sella and well away from the margin ; the volsellse rather short in com- parison with the other parts of the genitalia and unusually densely and evenly hairy over their entire surface as seen from the ventral side and without noticeable projections of any sort, except the small, elongate and rather slender apical projections ; the squamae strongly bilobed, the two lobes being about equal in size, the outer lobe being slightly the longer and the inner one somewhat the broader, the outer TRANS. AM. KNT. SOC, XXXIX. 172 AMERICAN HYMENOPTERA. one tapering to a bluntly pointed apex and with its outer dorsal face somewhat excavated and the inner one broadly rounded at the apex. Sagittae with very long shafts, these shafts being without any notice- able projection on their middle portion and being constricted just in front of the heads ; the heads reaching back nearly to the apices of the volsellse, being considerably foliaceous in form and extending ventrad and mesad from the ends of the shafts, their outer margins being distinctly serrate. Uncus (fig. 192) at most only moderately broad, its apical portion being recurved ventrad and broadly rounded at tip. IVings .—Only moderately infuscate, rather light. Transverse me- dian vein of fore wings not coalescing at all at base with base of discoidal and curved somewhat so as to form a slightly obtuse inner angle with both the median and the anal vein. Legs.— All black. Outer faces of hind tibiae flattened, though some- what concaved behind, and with very sparse hairs, almost completely naked, the fore fringes moderate and the hind ones long, forming dis- tinct, though weak, corbiculse. Hind metatarsi with outer faces fiat or slightly concaved and moderately and rather evenly hairy ; their hind fringes long and black ; about three and one-half times as long as their greatest width. Dimensions. — Length: worker (according to Friese), 13 mm. to 14 mm. ; male (according to Friese), 16 mm. to 17 mm. (the specimen before me is between 13 mm. and 14 mm. in length). There is a single male before me from Callanga, Peru, which I received from Staudinger. This male differs some- what from the typical form described above, and it may be described as follows : Male Color Variant. — Like typical male, but with first dorsal abdomi- nal segment entirely black ; second and fifth segments covered with en- tirely coccineo-ferruginous pile ; sixth segment with mostly coccineo- ferruginous pile, but with some short black hairs in middle and with a scanty admixture of very long whitish hairs throughout ; segment seven clothed with pale ferruginous pile tipped with whitish. The typical male is here redescribed from a single speci- men from Peru (Cuzco— 10,400 feet to 13,600 feet altitude), received from H. Friese and labelled " Bombus coccineus'' by him. The worker is also redescribed from a single speci- men determined by Friese and received from him. This species appears to have its closest relatives in baeri and butieli. The red pile of the specimen before me is per- haps best described as coppery-ferruginous. henry j. franklin. 173 South and Central American and Mexican Species of psithyrus. Females of only two and males of only two species of Psithyrus have to my knowledge been collected in the New World south of the United States. One of the males has not been heretofore described. It is closely related to con- sultus and may be a variation of that species, or it may be the male of intrudens. I have seen fit, however, to describe it here as new, from the single specimen before me. The two species of females may be conveniently separated from each other and from variabilis and instilaris, the two United States species females of which are likely to be found in Mexico, by the following key : Abdomen entirely black above 1. Abdomen not entirely black above 2. 1. Mesopleura yellow iiitrutlens. Mesopleura black variabilis. 2. Mesopleura mostly black ; third and fourth dorsal abdominal seg- ments with white pile brasiliensis. Mesopleura mostly yellow ; dorsum of abdomen with black and yel- low pile only iusularis. The males may be distinguished from cortsjilius and the male of variabilis, the two United States Psithyrus males likely to be found in Mexico, by the following key : Mesopleura covered with yellow pile to bases of legs 1.

Mesopleura yellow to bases of legs. Metapleura mostly dark. Sides of median segment mostly dark, but with a slight admixture of yellow hairs on their upper portions. Abdomen. — Dorsum : segment one entirely covered with yellow pile; segment two also yellow, but with a considerable area on each ante- rior corner bearing black pile ; segment three with yellow pile on each side, but black in the middle, the dark area being widest on the front margin of the segment (where it is more than one-third as wide as the whole segment) and narrowest on the hind margin (where it is about one-fifth as wide as the segment); segment four black except for yel- low pile on extreme sides ; segments five, six and seven entirely black. Venter mostly black, but with apical margin of apical segment fringed with short ferruginous hairs. Wings. — Rather light, only moderately infuscate. Legs. — Mostly black.

I have not seen a specimen of this species, but I judge it may be closely related to sololensis. Cockerell's description is as follows : " Length about 17 mm. ; anterior wing \\\.

(The male of the European P. guadricolor, Lep., has even shorter hair on hind basitarsus, but long hair on the tibia.

''Female. — Black; a tuft on the vertex and another in front of the anterior stemma pale yellow ; the thorax clothed above with pale pubes- sence, which is continued down the sides in front of the tegulae ; the thorax smooth and shining behind the scutellum ; the legs with very short black pubescence; the wings fusco-hyaline. Abdomen nearly naked, shining, incurved and very acute at the apex, the margins of the segments thinly fringed with black pubescence." '' Hab. Oajaca, Mexico," Handlirsch apparently had a specimen of Smith's species. He had a single specimen from Mexico (Puebla). He re- marks concerning the species as follows : "This species agrees well with insularis in the plastic characters, but is considerably smaller, 18 mm. The wings are rather strongly infuscate, the thorax and the upper half of the head is yellow, all the remainder is black haired. The callosities on the underside of the sixth segment are somewhat less sharply impressed than in itisularis.'" This species appears to be much like laboriosus in colora- tion, and it probably belongs to the Laboriosus Group. Psithyrus brasiliensis (F. Sm.) D. T. Apathus brasiliensis Smith, Cat. Hym. Brit. Mus., II, 1854, p. 385, n. 8, 9. Psithyrus brasiliensis Dalla Torre, Cat. Hym., X, 1896, p. 566. Type. — Smith's specimen was located for me in the collec- tion of the British Museum by Col. C. T. Bingham. I have never seen this species. Smith's description is as follows : '' Female.— Length. 7 lines. Black; head subrotundate, the face clothed with black pubescence, that on the vertex mixed with a few yellow hairs. Thorax clothed anteriorly with long yellow pubescence ; the disc shining, thinly covered with black hairs; the metathorax, the sides and beneath have also a black pubescence ; the wings subhya- line, their nervures ferruginous. Abdomen shining, the base thinly clothed with black pubescence ; on the third and fourth segments it is white, but on the apical ones it is black ; the apical segment incurved, nearly naked and acute." ''Hub. Brazil (Para)." While this seems to be a true Psithyrus, I doubt if it was ever taken in Brazil, for the following reasons : 1. The original description mentions white pubescence on the third and fourth segments of the abdomen. The loca- HENRY J. FRANKLIN. 177 tion and climate of Para, Brazil, does not call for pile of that color on any species of the family Bombidae. 2. No species of Bombus at all similarly colored has ever been reported from Brazil. 3. No other really tropical species of Psithyrus has ever been captured in the New World. Intrudens, sololejisis and guatemalensis came, to be sure, from the tropics, but the first of these species inhabits a mountainous region of Mexico and the two latter live in the high mountains of Guate- mala, so they must be considered Lower Austral rather than Tropical forms. Unclassified Names and Descriptions. Such names and descriptions are here brought together as the writer has been unable to place with certainty, and it is hoped that, if any of them can be made to apply satisfactorily, some future worker on this family of insects may be helped by their being collected here.

The description given by Fabricius is as follows : " A. hirta flavescens capite anoque nigris. Habitat in America boreali. Statura praecedentis " (= B. fervidus) " at thorax immaculatus." I am of the opinion that fervidus was originally described from a worker and that alatus was the same as the Apathus citrinus (= male of P. laboriosus) of Smith, which might easily be of the same size as a worker of fervidtis. No other species of the North American BombidcB to my mind answers the description so well. The description, however, is very meager, and the species must remain in doubt unless the type of Fabricius is sometime discovered and recognized. It is impossible to say what the Apathxis elatus of Bowles (Ann. Rep't Ent, Soc. Ont., 1880, p. 33) was. It may have been P. iyisularis F. Sm.

SOC. , XXXIX. 182 AMERICAN HYMENOPTERA. 3. Laboriosus Group. Not certainly known to be represented in the Old World. 4. Other Groups. Campestris (Panz.) and barbutelhis (Kirby) represent two distinct groups not found in the New World, and rupestris (F.) apparently represents a third, though that species seems to show some affinities, in its male genitalia, with the species of the Laboriosus Group. Genus BOMBUS. A. Subgenus Bonibias. 1. AuRicoMUS Group. Not certainly known to be represented in the Old World, but, as the species nevadensis probably ranges through Alaska, the chances seem good that the group is present in Asia at least. Vorticosjis, as described and figured by Schmie- deknecht (Apid. Europ., I, P. 5, 1883, p. 319, n. 11, 9 5 cf ; T. 8, Fig. 7) , appears to be rather closely related to the species of this group and it may really belong to it. 2. Fraternus Group. Not certainly known to be represented in the Old World. B. morawitzi Rad. has the male genitalia of this group, but I know little about the species otherwise. B. vorticosus Ger- staecker, if the figures of Radoszkowski (Bull. Soc. Natural. Moscou, LIX, 1884, p. 67, F. 11) are correct, also has male genitalia nearly typical of this group, but Radoszkowski de- scribes nothing but the genitalia and, as figured by him, they are certainly much different from those figured and described by Schmiedeknecht (Apid. Europ., I, P. 5, 1883, p. 319, n. 11, 9 5 cf ; T. 8, Fig. 7) as those of vorticosus. I have examined the genitalia of the male of mastrucatus Gerstaecker (the genitalia which I examined being those of a male determined by Schmiedeknecht), and I found them to be like those of the Fraternus Group. Furthermore, the hind metatarsus of the male of that species has a good fringe of long hairs on its hind border as it does in the species of this group. The eyes and the ocelli, however, are, in all the castes, as in the subgenus Bofnbus. Moreover, the mandi- HENRY J. FRANKLIN. 183 bles of the females (I have examined those of a worker deter- mined by Schmiedeknecht and found them to be as described and figured by him in Apid. Europ., I, P. 5, 1883, p. 373; T. 12, Fig. 2) are distinctly six-toothed. I know of no other species of Bombjcs normally with more than four distinct teeth to the mandible, and Schmiedeknecht (vide supra) states that niastrzicahis may be readily distinguished from all other species of bumble-bees by means of the toothed man- dibles of its females. Is not this remarkably specialized structure of the mandibles due to some peculiar specializa- tion on the part of this species in its habits of nest building? The genitalia of the male of alpigenus Morawitz, as figured by Radoszkowski under the name ivurfleini (Bull. Soc. Natural. Moscou, LIX, 1884, p. 65; T. 1, Fig. 9), would place that species in this group, but I know nothing of its other characters. Schmiedeknecht (Apid. Europ., I, P. 5, 1883, p. 373) placed alpigemis as a variety of mastrucatus. 3. Other Groups. B. vorticosjis Gerstaecker (as described and figured by Sch- miedeknecht in Apid. Europ., I, P. 5, 1883, p. 319, n. 11, 9 $ cf; T, 8, Fig. 7), mendax Gerstaecker (as described and figured by Schmiedeknecht in the same work), and con- fusus Schenck all belong to the subgenus Bo7)ibias. I have seen a worker of mendax, determined by Schmiedeknecht. Its ocelli were placed distinctly below the supra-orbital line, but slightly above the narrowest part of the vertex, the lateral ones being nearer to the margins of the eyes than to each other. I have seen specimens (determined by Schmie- deknecht) of all three castes of conhcsus and have examined the genitalia of the male. Many of the characters of this species, if other characters were not considered, would place it readily in the Fraternus group. The ocelli of the females are large and placed in the narrowest part of the vertex, well below the supra-orbital line, the lateral ones being nearer to the margins of the eyes than to each other ; the eyes of the male are greatly swollen and the ocelli are placed in the narrowest part of the vertex, at about one-third of the dis- TRANS. AM. KNT. SOC, XXXIX. 184 AMERICAN HYMENOPTERA. tance from the supra-orbital line toward the bases of the an- tennae, the lateral ones being separated from the margins of the eyes by less than their own diameter ; the hind meta- tarsi of the male have fringes of long hairs on their poste- rior borders. On the other hand, however, the clypeus of the queen and worker is finely and evenly punctate over its entire surface as with the species of the Atiricomus group, and the third antennal segment of the male is nearly equal in length to the fourth and fifth taken together, Vorticosus may belong to the Auricomus group or it may represent a group not found in the New World. From Schmiedeknecht's figure of the male genitalia of mendax and from my own examination of the genitalia of confusus, I am sure that those two species represent two groups not present in the New World. The Coiihisus group seems more nearly allied to the Auricomus group than to the Fraternus group. B. Subgenus Bombus. 1, DuMoucHELi Group. dumoucheli Rad., from southern Siberia (Irkutsk and Nerchinsk). 2. Pratorum Group. alticola Kriechbaumer. ? consobrinus Dahlbom. haematurtis Kriechbaumer. hypnorum (L.). lapponicus (F.). ? modestus Eversmann. pratorum (L.). jonellus Kirby. ussurensis Rad. I have examined the male genitalia of lapponicus (taken from a specimen determined by Schmiedeknecht). As the descriptions and figures, given by Radoszkowski (Bull. Soc. Natural. Moscou, LIX, 1884, pp. 59-62 and plates) and Sch- miedeknecht (Apid. Europ., I, P. 5, 1883), of the genitalia of the males of alticola, haematurjis, hypnorum, pratortim, jonellus (= scrimshiranus) and ussurensis agree, I have no hesitation in placing these species in this group. Conso- brinus and modestus, if Radoszkowski (Bull. Soc. NaturaJ. HENRY J. FRANKLIN. 185 Moscou, LIX, 1884, pp. 59-61) is correct, also belong cer- tainly to this group, though I have no evidence to show that this is so, aside from Radoszkowski's opinion. There are probably still other species in the Old World, with the char- acters of which I am not familiar, which belong to this group. I have examined the male genitalia of lapidarius (taken from a specimen determined by Schmiedeknecht) and find that, in many respects, they resemble closely those of the species of the Pratorum group. Each squama, how- ever, has a distinct, though not very well developed, inner lobe, and the head of each sagitta extends mesad in a long spine-like projection, but is not falcate. I am inclined to con- sider this structure of the genitalia as representing, in a large measure, the very primitive structure of the genitalia of the Pratorum group. It should be noticed that Radoszkowski (Bull. Soc. Natural. Moscou, LIX, 1884, p. 62) made lapi- darius the typical species of a group in which he also placed caucasiais Rad. and eriophor^is Klug. 3. KiRBYELLUS GROUP. a/pinus (L.) . hyperboreiis Schonherr. balteatus (= nivalis) Dahlbora. These three species have been placed in this group by means of Schmiedeknecht's descriptions (Apid. Europ., I, P. 5, 1883) of them, particularly by his descriptions of their male genitalia. 4. BoREALis Group. distinguendus Morawitz. ? /ra^raw^ (Pallas). latreillellus (Kirby). I have seen specimens of both distinguendus and latreillellus labelled by Schmiedeknecht and have examined the male genitalia of the latter species. The figures of the genitalia of both these species, given by Radoszkowski (Bull. Soc. Natural. Moscou, LIX, 1884) and Schmiedeknecht (Apid. Europ., I, P. 4, 1882), agree very well and indicate that they are much like the genitalia of borealis and appositus. The figure of the male genitalia of fragrans, given by Sch- TRANS. AM. ENT. SOC, XXXIX. (24) 186 AMERICAN HYMENOPTERA. miedeknecht (Apid. Europ., I, P. 5, 1883 ; T. 11, Fig. 4), would place that species at once in this group, and Schmiede- knecht's description of the species as a whole seems to indi- cate that it is in general much like the species known to be- long in this group. The figures, given by Radoszkowski (Bull. Soc. Natural. Moscou, LIX, 1884, Tab. IV, figs. 36 a, b and c), however, as those of the male genitalia of fra- grans, represent genitalia quite different from those figured by Schmiedeknecht as belonging to that species. The stand- ing of fragrans is, therefore, in doubt, but with the chances in favor of its belonging to the Borealis group. 5. Terrestris Group. Jairmairi ^\c\\q\. (From Kunawar, India). portchijtski Ka.d. (From Caucasus). terrestris (L.) . I have placed {air7nairi and portchinski in this group by the descriptions and figures of their male genitalia given by Radoszkowski (Bull. Soc Natural. Moscou, LIX, P. I, 1884, pp. 80 and 82 ; T. 3, Figs. 31 and 33). 6. Other Groups. There are several distinct Old World groups belonging to the subgenus Bombus, which are not present in the New World. I have been able to distinguish at least six such groups, as follows : (a). Hortorum Group. Including hortoru^n (L.) and argillaceus (Scopoli) and per- haps other species. I examined the genitalia of a male hortorum, determined by Schmiedeknecht, and found them to be as figured by Radoszkowski and Schmiedeknecht. (b). Soroeensis Group. Including soroeensis (F.) and radoszkowskyi D. T. (= \\ per- plexes Rad.) and possibly other species. I examined the genitalia of a male so7'oee?isis, determined by Schmiedeknecht, and found them to be as figured by Radoszkowski and Schmie- deknecht. I have never seen a specimen of radoszkowskyi, but follow Radoszkowski in placing it in this group, as his figures indicate that the male genitalia are much like those of soroeensis. HENRY J. FRANKLIN. 187 (c). Sylvarum Group. Including sy /varum (L.), eqtiestris (F.) (= arenicola Thom- son ?), molkoseuntsi Rad. and possibly other species. I have seen no specimen of this group, but Radoszkowski's figures of the male genitalia of these three species (Bull. Soc. Natural. Moscou, LIX, 1884, pp. 73 and 74; Tab. II, Figs. 20, 21 and 22) are enough to make it certain that they repre- sent a group distinct from all the others known to me. Ra- doszkowski's figures seem to indicate that these species are more primitive than any of the New World species, (d). PoMORUM Group. YnoXu^mg pomo7'um Panzer, 7nesomelas(j&x^\.Q.Q.z\iQ.x and pos- sibly other species. I examined the genitalia of a male pomoriun determined by Schmiedeknecht and found them to be as figured by Schmiedeknecht and Radoszkowski. I have included mesomelas in this group because Radoszkowski's figures of the genitalia of that species (Bull. Soc. Natural. Moscou, LIX, 1884; Tab. II, Figs. 19 a, b and d) represent genitalia much like those oi pomoriun. This group is closely allied to the Dimioiicheli group, (e). DivKRSus Group. Including diversus and possibly other species. I establish this group entirely on Handlirsch's figure (Ann. Naturh, Hofmus. Wien., Ill, 1888, p. 214 ; T. 10, Fig. 10) of the male genitalia of diverstis. Diversus is from Japan and appears to have rather close afifinities with the Dumoitcheli group, (f). Tristis Group. Judging by the figures given by Radoszkowski (Bull. Soc. Natural. Moscou, LIX, 1884, p. 75), this group, as estab- lished by him, is valid, though it evidently has rather close affinities with the Diunoncheli group. Judging by Radoszkowski's figures (ibid.. Tab. IV, Figs. 37, a and b) of the male genitalia of stevenii (= 207iattis var. ?), that species should have also been included m the Tristis group. If the figures of the male genitalia of agrorum (F.) given by Schmiedeknecht (Apid. Europ., I, 1883) and Radosz- kowski (Bull. Soc. Natural. Moscou, LIX, 1884) are correct, that species probably represents still another group not found in the New World. TRANS. AM. ENT. SOC, XXXIX. 188 ♦ AMERICAN HYMENOPTERA. INDEX TO PART II.

Included below, with the descriptions of various new genera and species, are synopses of the genera of Panos- pidae, Osmylinae, Hemerobiinae, Mantispidae, South Ameri- can Myrmeleonidae and a new classification of the Perlidae ; most of the synoptic work is a result of a study of several European collections. The types of all the new species described in this paper are in the author's collection. PERLIDAE. Twice I have published classifications of the American Perlidae. After seeing several genera (hitherto unknown to me) in European museums I have prepared a new ar- rangement, which, however, differs little from the others as far as American species are concerned, but places in the same scheme the various exotic genera. For the principal character I would use the shape of the anterior part of the head. 1. Clypeus practically invisible, or only projecting from beneath the raised margin of the front of the head ; tarsi with the last joint very much longer than the first and second together, the first joint barely, if any longer, than the width of the tibia at tip ; coxae I widely separate ; setae present ; no series of cross-veins in the cubito-anal space PERLINAE. Clypeus visible in continuation of the general surface of the head, and separated by a suture from the head ; tarsi with the last joint but little or not longer than the first and second together, the first joint longer than the width of the tibiae at tip, last joint of palpi as large as others 2. 2. Many cross-veins in the apical part of fore wings ; median vein not united to the radius near base ; setae well developed ; second tarsal joint much shorter than others. ..PTERONARCINAE. Few cross-veins in the apical part of the fore-wings ; median vein united to the radius toward base ; first and second tarsal joints together longer than the third ..NEMOURINAE. TRANS. AM. ENT. SOC. , XXXIX. (26) 202 EXOTIC NEUROPTERA. Subfamily Perlinae may be divided into two tribes as follows : Median vein united to radius near base ; anal cell with one branched vein Chloroperlini. Median vein not united to radius near base, but running closely paral- lel thereto; anal cell with two veins Perlini. The Chloroperlini include three genera, Chloroperla and Alloperla in which the last joint of the maxillary palpus is very minute, and Paraperla in which this joint is well devel- oped. Paraperla also has a series of cubital cross-veins in the hind wings. In venation this tribe is remarkably similar to the Nemourini, but differ by well developed setae and the retracted clypeus. The Perlini includes many genera, most of which I have tabulated in my tables of American Perlidae or are given by Enderlein (Zool. Anzeiger, xxxiv, p. 388, 1909). I cannot consider the number of ocelli as of importance in grouping genera, since one of the two ocelli genera — Hemacroneuria, is evidently more related to Acroneuria than to Neoperla. The genus Ochthopetina made for Old World Neoperlas is very doubtfully distinct from Neoperla. Macrogynopiax dif- fers from Neoperla only in the female genitalia. Cryptoperla differs from Neoperla in the hairy eyes and frontal ridge of head. Niponiella I would consider as Acroneuria, Dictyo- genus as Isogenus, and Dictyopterygella as a Perlodes. The several divisions of Perlodes and Isoge7ius made by Klapalek are hardly more than subgenera, and mostly based on geni- tal characters. Tropidogonopl ax is about the same as Och- thopetina and Tavanita a synonym of Ochthopetina. Subfamily Pteronarcinae may be divided into three tribes as follows : Anterior coxae more approximate than the others ; many costal cross- veins ; no cross-veins in the cubito-anal space of the fore- wings Pteronarcini. Anterior coxae widely separated ; no series of cross-veins in cubito- anal space; few costal cross-veins Leptoperlini. Anterior coxae widely separated ; a series of cross-veins in the cubito- anal space of fore-wings Eusthenini. The Eusthenini includes three genera ; Ste7ioperla, green NATHAN BANKS. 203 in color, and with very few costal cross-veins, Diamphipnoa, which has many costal cross-veins, and Eiisthenia with partly red or violaceous wings, Diamphip7ioa has lichen-green wings, and the median series of cross-veins in fore wings is crossed. Diamphipnoa lichenalis Gerst. has the anterior coxae widely separated ; last joint of tarsi longer than the two others together ; ocellar triangle longer than broad behind ; the subcosta runs into the radius at tip ; many of the median cross-veins crossed ; a series of cross-veins in the cubito- anal region (not in Pteronarcys) . Etisthenia ihalia and E. diversipes belong to Austroperla. There are no series of cross-veins in the cubito-anal space, and the costal area has cross-veins all along ; the anal cell has two branches, setae very short. The two species are very similar. The genus Heteroperla Hare is a synonym of Austroperla. The Leptoperlini is the group of Antarc toper la of Ender- lein ; small, slender, dark species, looking much like Ne- mourini but with many cross-veins, sometimes only indi- cated, in the apical part of wing. The type of Leptoperla, L. beroe Newm. has slender legs, long antennae, and long setae, the last joint of tarsus not equal to the basal two ; the radial sector soon forks as seen in figure 29. In L. opposita the setae are shorter, the tarsi have last joint longer, and radial sector is simple, while the cubitus is forked as in figure 30. The genus Parantoperla is very close to L. oppo- sita. Aucklandobius is hardly distinct from Notoperla. The genera of this section may be tabulated as follows : 1. Many costal cross-veins ; setae very short Austroperla. Only one or two costal cross-veins 2. 2. Radial sector of fore-wings forked 3. Radial sector of fore-wings not forked 4. 3. Radial sector forked toward tip ; cubitus forked at the basal cross- vein Gripopteryx. Radial sector forked near base ; cubitus forked long before the basal cross-vein Leptoperla. 4. Hind-wings with cubital cross-veins. ..Notoperla {Aucklandobius) . Hind-wings without cubital cross-veins. Autarctoperla {Parantoperla). TRANS. AM. ENT. SOC. , XXXIX. 204 EXOTIC NEUROPTERA. Pictet's type of Gjdpopteryx cancellata has the vein from anal cell forked, two costal cross-veins, one near base, and one at tip ; hind wings with three cubital cross-veins near tip ; radial sector of fore wings with one branch, the median vein before the large basal cross-vein is rather weak but dis- tinct, in both wings the cubitus forks at this cross-vein ; last joint of tarsi plainly longer than basal two together; the setae with many very short joints. Paragripopteryx differs only in having a cross-vein beyond end of the subcosta. The Pteronarcini includes only the two northern genera, Pteronarcys and Pteronarcella occurring in northern North America and Siberia. The subfamily Nemourinae can be divided into two tribes as follows : Anal cell with one simple vein ; setae usually distinct Capnini. Including Capnia, Capnura, Capnopsis, Arsapnia and Capio- neura. Anal cell with a forked vein ; setae rudimentary Nemourini. Including Nemoura, Perlomyia, Udanioceria , Leuctra, Taeniop- teryx (with three subgenera) and Taenio7tema . Ochthopetina Clarissa n. sp.— Almost wholly clear pale yellow ; tips of palpal joints dark ; antennae beyond base brownish ; ocelli and eyes black ; tarsi rather dark ; last five joints of anal setae dark ; venation wholly pale yellowish, probably greenish when alive. Ocelli nearly contiguous ; lateral bosses smaller than ocelli, nearly round, and hardly more than their diameter from the lower inner edge of eyes. Pronotum broader in front than behind, slightly convex on front margin, sides with several prominent rugae; wings rather long, about ten costal cross-veins, several beyond end of the subcosta ; radial sector forked about the width of a cell beyond the anastomosis, four median cross-veins, four cubital cross-veins, and four branches of cubitus beyond.

Expanse 43 mm. Type. — cf. From Magnet, Tasmania (Lea). Easily distinguished from E. spectabilis by the violaceous wings as well as by the male genitalia. PSOCIDAE. Myopsociis eiiderleiiii n. sp. — Related to M. muscosus Ender. from Japan. The markings of the wings are very similar, the dark spot on the union of the cubitus and the median is here larger and darker colored, the stigma is pale, with a few faint dark dots near the costa, and there are more pale spaces along the veins in the apical part of the wing. The antennae and legs are pale grayish ; head brownish-yellow, unmarked. The venation is similar to M. muscosus, except that the stigma is a little more swollen at tip, and the outer side a little more oblique ; the median cell is rather broader and the cross-vein from it to the hind margin shorter than in M. muscosus ; the forking of the radial sector is also rather farther out than in that species. Length 5 mm. Type. — cf . From Los Banos, Philippines (Baker). MANTISPIDAE. In 1910 Dr. Enderlein published an excellent classification of the Mantispidae, but in several points it can be improved. The length of the radial cells is of such a comparative char- acter and so gradual in the variation from one species to another that it can hardly be used as a generic character ; the number of branches of the radial cells varies in some spe- cies. M. indica is given by Enderlein as type of Mantispilla with but one branch from the first radial cell, and so figured by Westwood, yet in one specimen of the type series (in British Museum) the first radial (as others) has two branches. However I think that Mantispa may be divided according to whether the pronotum is hairy or not, and by this Mantispa and Mantispilla remain, but most of the spe- cies are transposed from one genus to the other. Entano- fieiira falls as a synonym of Mantispilla. Dr. Enderlein separates Anisoptera and Trichoscelia also according to the number of branches to the first radial cell, Trichoscelia having but two ; yet in the type specimen of the genotype {T. {cjiella) there are two and a half, that is the TRANS. AM. ENT. SOC. , XXXIX. 206 EXOTIC NEUROPTERA. third is interstitial with end of the cell ; and in other species this character is still more variable. Therefore the two genera should be united, and the Anchieta of Navas is also a synonym as Enderlein has already put it. Ditaxis and Drepanicus are very close together, and per- haps identical; Molinella of Navas is the same as Dre- panicus. 1 Front tarsi with one claw ; front coxae divided more or less plainly into two parts MANTISPINAE-2.

In shape the fore-wings are plainly shorter and more truncate at tips than C. api- cale. Expanse the same. Type. — c?. From Rio Negro, E. Colombia, 800 meters (Fassl). Ceutroiiiacronenia exteiisiini n. sp. — Brown above, yellowish beneath ; antennae yellowish ; fore-wings nearly uniform brown, like some forms of C. aiiripenne, much of the hind-wings also similar, but paler behind than in front. In venation similar to C. auripenne, ex- cept the lower part of fork 5 is united for a short distance with the next vein (not connected thereto by a cross-vein); in the hind-wings the fifth fork extends much before the cross-vein. In shape the fore- wings are longer and more slender than C. auripenne ; and the last joint of the maxillary palpi, although very long, is not as long as in C. auripenne and C. apicale. Expanse 44 mm. Type. — 6^. From Lino, Panama, 800 m. (Fassl). CORDILLOPSYCHE n. gen.

Antennae reddish-brown, short and stout, 14-jointed, third joint as long as the first and second together, fourth shorter than the third, the following joints much shorter than the preceding and of equal size. Thorax black, opaque, finely and evenly granulated. All the grooves are narrow and sharply defined. Parapsidal grooves continuous and running obliquely to the scutellum, where they are rather widely separated. Median line fine and continuous. Anterior parallel lines extending to the middle of the thorax. Lateral grooves deep, very long and running parallel with the parapsidal grooves, but not extending to the anterior part of the thorax. Pleurae rugose and somewhat finely aciculated with a small smooth area situated posteriorly. Scutellum coarsely rugose, foveae at base large, deep and fairly well apart. Abdomen smooth shining reddish-brown, slightly pubescent at the extreme base. Legs dark yellowish-brown. Wings hyaline, veins yellowish-brown and semi-translucent ; radial area open, the veins almost touching the costal margin ; cubitus fine and extending to the first cross-vein, areolat large; second cross-vein angulate. Length 2.50-3 mm. Habitat. — Lakehurst, New Jersey. A fine large species with short stout antennae. The thorax is evenly granulated, and all the grooves are fine and distinct. I have taken a number of the flies ovipositing in the buds of white oak {Quercus alba) late in May, but I do not know what the gall is like. Cyuips diniorphiis sp. nov. Female. — Form robust. Head black, rugose and covered with short white pubescence. Antennae 14-jointed, joints 1-8 slender, subequal in length, 8th thicker at the tip, joints 9-14 short, thicker than the preceding, and forming a club, all pitchy brown-black. Thorax black with decumbent whitish hairs, distinctly and evenly rugose-punctate, subopaque ; parapsidal grooves fine and almost reaching the anterior TRANS. AM. ENT. SOC. , XXXIX. 246 AMERICAN HYMENOPTERA. part of the thorax, where they are inwardly curved ; anterior parallel lines short ; median groove wanting, lateral groove scarcely evident or wanting. All the grooves are punctate and almost lost in the rugosity of the thorax. Pleurae black and evenly rugose. Scutellum black, more rugose than the thorax and with short whitish hairs, the apex is well rounded and at the base are two rather large opaque foveae. Abdomen black, punctate and covered with short hairs. Legs: fore and middle pairs brownish, hind pair black, all pubescent. Wings hyaline, veins brown ; radial area almost closed ; areolet large ; cubitus very faint and not extending to the first cross-vein ; second cross-vein slightly infuscated and outwardly angulate. Length 2.50 mm. Gall.— In masses on the basal part of the midrib or petiole on the underside of leaves of burr oak {Qiiercus macrocarpa) , dwarf chestnut oak {Q . prinoides) , white oak {Q. alba) and other trees belonging to the white oak group. They occur in rounded masses from a few to about thirty in each cluster. They are closely packed together, but each gall is separate and easily detachable. They are fastened to the leaf by a point, rounded on top and but slightly pressed out of shape, except basally. Monothalamous, almost globular, pointed basally, with the surface roughened, greenish, and more or less tinged with pink when fresh. Grayish when old and very hard. Hollow inside with a single round larval chamber. The individual gall measures from 2.50-3 mm. in diameter. The masses are from 6-15 mm. long and almost as wide. Habitat. — Evanston, Illinois, collected by Lewis H. Weld. The galls occur from the latter part of August until late in October, or into November, when they become mature and detached from the leaf. The flies emerge during the spring the following year. I have found the galls of this species on Queracs alba and Q. prinoides on Long Island, New York, and in New Jersey, but never succeeded in obtaining the flies. The four females described above were cut from galls by Mr. Lewis H. Weld, May 11, 1911. Mr. Weld's galls were taken on Quercus macrocarpa late in August the pre- ceding year. The name for this species was proposed by the late Dr. W. H. Ashmead for specimens in his collection, but which he never described. Prof. C. P. Gillette recorded C. dimorpims from Michigan taken on the leaves of Quercus prinus, Q. macrocarpa and O. bicolor (Rep. Mich. Bd. Agricul., 1888, p. 469). Ashmead's specimens were collected in Florida. WILLIAM BEUTENMULLER. 247 Cynips vacciniiforiiiis sp. nov. Female. — Head very dark brown, microscopically rugose with scat- tered, large deep punctures and densely covered with whitish hairs.

Thorax black, minutely rugose with large pit-like punctures and densely covered with whitish hairs. Collar red on each side. Parapsidal grooves fine, sharp and smooth, widely separated anteriorly converging at the scutellum, where they are fairly well apart. Anterior parallel lines lost in the rugosity of this part of the thorax. Lateral grooves short and fine. Median groove wanting. Pleurae brown, rugose and covered with whitish hairs. Scutellum coarsely rugose, basal foveae not evident, except by slight depressions. Abdomen pitchy brown covered with short whitish hairs which arise from minute punctures ; dorsal region smooth and polished. Legs pitchy brown, hind femora blackish. Coxae dark brown and hairy. Wings hyaline, veins stout and brown ; radial area broad and closed ; second cross-vein angulate ; cubitus faint and continuous ; areolet large but faint ; anal vein broken. Length 4 mm. Gall. — In clusters on the midrib of post oak {Quercus minor), Monothalamous and moderately thick walled with a large round larval chamber. Globular and almost like a huckleberry or fruit of hack- berry {Celtis uccidentalis) with a more or less distinct nipple at the apex and long petiole or stem at the base by means of which it is attached to the leaf. Brown when old and probably green when fresh. The outer surface is slightly roughened or almost smooth. Diameter 4-7 mm. ; petiole 1-2.50 mm. long. Habitat. — Austin, Texas. The gall somewhat resembles that of C. dimorphiis, but is larger and more globose. It occurs in clusters like dimor- phus, but the galls are less closely together and not pressed out of shape, each individual gall retains its globose shape. The male is not known. Di'yoplianta cressoiii sp. nov. Female. — Head yellowish-brown, microscopically rugose and pubes- cent. Antennae long and slender, 14-jointed ; joints 4-7 about equal in length, 3d longest, 8th to last shorter than the preceding, brown, slightly darker terminally.
