SMITHSONIAN INSTITUTION, WASHINGTON, D.C., JULY, 1910 HARRIMAN ALASKA EXPEDITION WITH COOPERATION OF WASHINGTON ACADEMY OF SCIENCES ALASKA VOLUME IX INSECTS PART II BY WILLIAM H. ASHMEAD, D. W. COQUILLETT, TREVOR KINCAID AND THEO. PERGANDE NEW YORK DOUBLEDAY, PAGE & COMPANY 1904 COPYRIGHT, 1904, BY EDWARD H. HARRIMAN. PREFACE IT was originally intended to publish the entomological re- sults of the Expedition in a single volume, but when the reports from the various specialists came in, the quantity of matter was so great that it was found necessary to divide it into two volumes. The present volume contains papers on the Diptera, Tenthred- inoidea, Sphegoidea, Vespoidea, Formicidae, and Hymenoptera. In the latter group, Mr. Ashmead tells us, less than 30 species were known from Alaska prior to the Harriman Expedition, while the number here recorded is 335, of which 201 are de- scribed as new to science. This extraordinary increase is due almost wholly to the indefatigable activity of the entomologist of the Expedition, Professor Kincaid. C. HART MERRIAM, Editor. WASHINGTON, D.

Department of Agriculture, was originally published in the Proceedings of the Washington Acad- emy of Sciences, vol. n, pp. 389-464, Dec. 7, 1900. It is here reprinted from the same electrotype plates, so that it may be quoted exactly as if it were the original. The original pagination has been preserved and transferred to the inner or hinge side of the page, where it is enclosed in brackets, thus [390] ; while the consecutive pagination of the present volume has been added in the usual place. The present headpiece and title have been substituted for the running heading of the Academy's Proceedings and the original title, which was : Papers from the Harriman Alaska Expedition, ix. Ento- mological Results (j) : Diptera. , No other alterations have been made. Since the original publication of this paper the author has described as new, under the name Simulium fulvum, the species here (p. 7 [393]) referred to S. ochraceum Walker. (See Proc. U. S. Nat. Mus., xxv, p. 96, 1902.) The author desires to record the following additional corrections : Pages [39i]: Eighteenth line from bottom, enclose ' Meigen ' in parentheses.

COQUILLETT THE series of Dipterous insects collected by Professor Trevor Kincaid while a member of the Harriman Expedition to Alaska during the summer of 1899 is one of the most interesting and valuable collections of insects of that order that the U. S. Na- tional Museum has acquired for many years. The specimens themselves, almost without exception, are in first-class condi- tion, and each is accompanied by a label giving the exact lo- cality and date of capture. The collection contains 2,423 specimens, representing 276 species, distributed in 138 genera and 36 families. One genus and 63 of the species are believed to be new to science, and are described in this paper. In addition to the specimens referred to above, there are a number of others which it is quite impos- sible to correctly classify in the present condition of the science ; these are chiefly female specimens belonging to groups in which the sexes are very dissimilar in appearance, and the principal classificatory characters are present in the male sex alone, ob- scure groups which have not as yet been thoroughly studied in this country, and for the proper elucidation of which several years of careful study will be required. [389] (3) 4 COQUILLETT [S9°] As might naturally have been expected, the greater number of the species represented in the present collection are such as occur over the more northern portion of this Continent, not ex- tending farther southward than the mountains of New Hamp- shire and Colorado. Besides the new genus Ornithodes, which belongs to the family Tipulidae, the most interesting addition to our genera is the genus Telmatogeton, of the family Chirono- midae, heretofore known only from St. Paul Island, in the Indian Ocean. Family MYCETOPHILID.E. Diadocidia borealis sp. nov. Head and antennae dark brown, two basal joints of the latter, also the proboscis and palpi, yellow ; thorax polished, yellow, the dorsum, except the front corners, dark brown, scutellum yellow, metanotum brown; abdomen dark brown, slightly polished, its hairs yellowish; coxae and femora light yellow, tibiae and tarsi brown, front tarsi slender ; knob of halteres yellowish brown ; wings hyaline, densely covered with short hairs, auxiliary crossvein present, tip of first vein about opposite apex of anterior branch of the fifth. Length 4 mm. A male specimen, collected June 3. Habitat. — Lowe Inlet, British Columbia. Type. — Cat. no. 5190, U. S. National Museum. Closely related to the European D. ferruginosa Meigen, of which species the U. S. National Museum contains two specimens from the White Mountains, New Hampshire ; but in that species the apex of the first vein is far before the tip of the anterior branch of the fifth, the auxiliary crossvein is wanting, etc. Hesperinus brevifrons Walker. Hcsperinus brevifrons WALKER, List Dipt. Ins. British Museum, I, p. 8 1, 1848. Popof Island, Alaska : A single specimen, collected July 8. This species was originally described from Hudson Bay, British America, and has been recorded from the mountains of New Hampshire and Colorado. The genus Hesperinus has heretofore been placed in the family Bibionidae, but it differs from all the other members of that family by the elongated antennae. In this and other structural char- acters it agrees very well with the members of the present family. [391] DIPTERA 5 Necempheria kincaidi sp. nov. Head and its members black, second joint of antennae yellow, about one-half as long as the third, the three ocelli in a transverse row and widely separated from each other; thorax black, opaque, gray prui- nose, the mesonotum marked with four polished vittae, scutellum black, the base narrowly yellow, its hairs and those of the thorax golden yel- low; abdomen brownish black, slightly polished, its hairs yellowish ; coxae and femora yellow, tibiae yellowish brown, tarsi dark brown, front tarsi toward their apices noticeably higher than wide ; halteres yellow ; wings hyaline, bare, auxiliary vein ending in the first before middle of inner submarginal cell, the latter about twice as long as wide, anterior fork of fourth vein about ten times as long as preced- ing section of this vein, fifth vein forking far before small crossvein, the latter shorter than first section of third vein. Length 6 mm. A female specimen, collected July 8. Habitat. — Popof Island, Alaska. Type. — Cat. no. 5191, U. S. National Museum. Readily distinguished by its venation from any of the described species.

Black, the halteres yellow ; head bluish gray pruinose, the entire front brownish gray pruinose, only two vertical bristles (the anterior) present, ocellar and postocellar bristles present, two pairs of fronto- orbitals ; face in profile strongly concave, the clypeus unusually large and projecting the length of the third antennal joint beyond the ante- rior edge of the oral margin, cheeks posteriorly two-thirds as broad as the eye-height, third joint of antennae orbicular; body bluish gray pruinose, mesonotum largely brownish pruinose, five pairs of dorso- central bristles, scutellum bearing three pairs of marginal bristles, pleura and legs destitute of bristles except at apices of tibiae ; wings grayish hyaline, stigma and base of costal cell yellowish gray, apex of first vein opposite the hind crossvein ; length 6 to 7 mm. Four males and three females. Habitat. — Metlakahtla, June 4 ; Farragut Bay, Alaska, June 5. Type. — Cat. no. 5254, U. S. National Museum. (Edoparea was founded by Dr. Loew in the Zeitschrift fur Ento- mologie zu Breslau for 1859, page 10, and has for its type species the Heteromyza buccata of Fallen. Dr. Loew draws attention to the fact that in his original definition of the genus Heteromyza, Fallen stated that the vibrissae are present, but as a matter of fact, this is true of only one (oculatd) of the two species which he places in it ; oculata therefore must be considered the type species of the genus Heteromyza. About three years previous to the publication of Dr. Loew's article, Rondani had selected buccata as the type of a new genus, to which he applied the name Heterostoma, but upon discovering that this name had been previously used for another genus, he changed it the follow- ing year to Heterocheila. But this name was, in his opinion, too near to the previously employed generic term, Heterocheilus, and, accordingly, eleven years later he again changed it to Exocheila. As the name proposed by Dr. Loew had been published about nine years previously, it will, of course, take precedence over the name bestowed by Rondani. Sciomyza glabricula Fallen.

This is a European species, first reported from this country by the writer in 1895. It was recorded from the District of Columbia, and the National Mu- seum also contains specimens from Connecticut and New Hampshire. The characters heretofore used for separating Drosophila from Scap- [463] DIPTERA 77 tomyza have been rather vague and obscure, and in consequence the last-named genus has not been generally adopted. A recent study of this group has disclosed a well-marked difference in the disposition of the short, bristly hairs of the mesonotum ; in Scaptomyza these hairs are sparse and are arranged in two or four nearly regular rows, while in Drosophila as restricted they are numerous and not arranged in two or four rows. This difference, taken in connection with the widely divergent habits of the larvae — leaf-miners in Scaptomyza, scavengers in Drosophila — will justify the separation of these two forms into two distinct genera.

THE TENTHREDINOIDEA OF THE EXPEDITION (79) The following account of the Tenthredinoidea of the Expedition, by Trevor Kincaid, Professor of Biology in the University of Washington at Seattle, was originally published in the Proceedings of the Wash- ington Academy of Sciences, vol. n, pp. 341-346, Nov. 24, 1900. It is here reprinted from the same electrotype plates, so that it may be quoted exactly as if it were the original. The original pagination has been preserved and transferred to the inner or hinge side of the page, where it is enclosed in brackets, thus [343] ; while the consecutive pagination of the present volume has been added in the usual place. The present headpiece and title have been substituted for the running heading of the Academy's Proceedings and the original title, which Was : Papers from the Harriman Alaska Expedition. vn.

(80) THE TENTHREDINOIDEA OF THE EXPEDITION BY TREVOR KINCAID THE writer being the only member of the Harriman Expe- dition especially interested in entomology, the duty devolved upon him of securing as large a representation as possible of the insect fauna of the regions visited. Fortunately the condi- tions were more favorable than is usually the case in the ex- ploration of these northern latitudes. Every facility that expe- rience and forethought could suggest had been provided, and the work was further facilitated by the careful organization of the party. Moreover the labors of the collector were only slightly interfered with by unpropitious weather, which is the more remarkable in a region notorious for its excessive hu- midity and long continued rains. Recognizing the fact that almost nothing was known con- cerning the insect fauna of Alaska outside of the orders Coleoptera and Lepidoptera, a special effort was made to secure representatives of groups which, from the small size or obscure habits of their members, had not hitherto been collected in the Territory. This endeavor was so successful that the resulting collection contains by far the most extensive general series of [340 (81) 82 KINCAID [342] insects ever brought from the region. It will enable entomol- ogists to form an idea of the rich field that awaits them in this vast northern possession of the United States. The collection embraces in all more than 5,000 pinned in- sects, together with a considerable series of Arachnida, Myriopoda, and larval forms preserved in alcohol. The exact number of species represented cannot be stated at the date of writing, as not all the reports are completed, but the total will not fall far short of 900, distributed in the several groups as follows : Arachnida, 53 ; Myriopoda, 10 ; Thysanura, 10 ; Neuropteroids, 32 ; Odonata, 10 ; Aphididas, 4 ; Psyllidag, 3 ; Jassidae, 10; Heteroptera, 14; Orthoptera, i ; Coleoptera, 159; Diptera, 276; Rhophalocera, 12; Heterocera, 60; Apoidea, 12; Sphegoidea, 6 ; Vespoidea, 3; Formicoidea, 4; Parasitic Hymenoptera, 150 ; Tenthredinoidea, 56. Of the above, up- wards of 200 species are new to science, and of the remainder a large number are either new to the North American Continent or not yet recorded from Alaska. The collections were made between the first of June and the first of August, 1899. Except a small number of specimens ob- tained in British Columbia, all of the material was collected in Alaska. Most of the stops were made in going northward and westward, a few on the return journey. Collections were made at the following localities, which for convenience are arranged in geographic sequence, with date of visit : Fox Point, July 26-28 ; Metlakahtla, June 4 ; Farragut Bay, June 5 ; Taku Inlet, June 6; Muir Inlet, June 9-12 ; Juneau, July 25 ; Sitka, June 14-16; Yakutat Bay, June 18-22; Virgin Bay, Prince William Sound, June 25-26 ; Orca, Prince William Sound, June 27; Saldovia, Kenai Peninsula, July 21; Kukak Bay, Alaska Peninsula, June 29~July 5 ; Kadiak, July 20 ; Popof Island, July 7-17. Upon the return of the Expedition the collections were prop- erly labeled and assorted into groups, after which they were transmitted to Dr. L. O. Howard, Chief of the Division of En- tomology of the U. S. Department of Agriculture and Curator of Insects U. S. National Museum, for distribution to specialists for study and report. It is expected that these reports, twenty [343] THE TENTHREDINOIDEA 83 or more in number, will appear in the Proceedings of the Washington Academy of Sciences, and later in the final report of the Harriman Expedition. The systematists who have the various groups in hand are as follows : Arachnida .... Nathan Banks. Diptera D. W. Coquillett. Myriopoda . . . . O. F. Cook. Lepidoptera . . . . H. G. Dyar.

The collection of sawflies upon which the following report is based was gathered by the writer while with the Harriman Expedition in Alaska, and consists of about 350 specimens, representing 56 species, of which a considerable number are believed to be new to science. Very little is known concerning the sawflies of Alaska, only seven species having been recorded from this great Territory. In 1822 Eschscholtz1 described four species from Unalaska ; in 1872 Norton2 recorded a variety of Dolerus similis from the Yukon; in 1880 Cresson3 described a form of Trichiosoma triangulum from the Aleutian Islands ; in 1894 Harrington4 de- scribed a Tenthredo from Fort Wrangell, and in 1896 Marlatt5 recorded a species of Pachynematus from the same locality. It is clear that hardly a beginning has been made towards bringing to light the insect fauna of this vast and peculiar region, except perhaps in the Coleoptera, which were carefully collected by the Russians. Among the sawflies we may expect an especially rich series of Nematidae owing to the immense abundance, both in species and individuals, of various kinds of willows. 1 Eschscholtz, Entomogr., 1822.

Canada, Hymen., p. 210, 1883. Emphytus nigrofasciatus DALLA TORRE, Cat. Hym., I, p. 119, 1894. In 1822 Eschscholtz described two sawflies from Unalaska, to which he gave the names Tenthredo nigrofasciata and Tenthredo subcce- rulea. The latter has since been rediscovered and is a genuine Ten- thredo, but the generic position of his Tenthredo nigrofasciata has been in considerable doubt. Norton in discussing this species in his catalogue suggests that it might be a Macrophya. Kirby in his list of the Hymenoptera in the British Museum places it doubtfully in Em- phytus, and in this he is followed by Dalla Torre in his catalogue of the Tenthredinidae and Uroceridae. [361] THE TENTHREDINOIDEA IOI Specimens of a Tenthredinid taken at Unalaska and at other points in Alaska agree very perfectly with the description given of Ten- thredo nigrofasciata. If this conclusion is correct then Eschscholtz's species must have been a Pachyprotasis, to which genus the species above referred to belongs. On further investigation it was found that this Alaska Pachyprotasis is specifically the same as Pachyprotasis omega Norton, which is known to occur throughout the greater part of the United States and Canada, and is recorded from the Pacific coast, Labrador, and Saskatchewan. Six specimens, Unalaska, August 24; Popof Island, July 13; Unga Island, July 21 ; Virgin Bay, June 26. MACROPHYA OREGONA. Macrophya oregona CRESSON, Trans. Am. Ent. Soc., vni, p. 19, 1880. One specimen, Saldovia, July 21. This species was described from Oregon, but is also found in Washington. TENTHREDO FERRUGINEIPES. Tenthredo ferrugineipes CRESSON, Trans. Am. Ent. Soc., vni, p. 22, 1880. This is one of the commonest of the Alaska Tenthredos, and is represented in the collection by some fifty specimens, from almost every locality touched at, including Sitka, Virgin Bay, Saldovia, Kadiak, Kukak Bay, and Popof Island. It was originally described from Colorado, but it is known to be widely distributed on the Pacific coast and in British America. Males and females were about equally abundant; the former differ considerably from the opposite sex in shape, which is as usual much narrower, and in coloration ; the abdo- men is bright red in the middle but the basal plates and the three apical segments are black. TENTHREDO VARIPICTA. Tenthredo varipicta NORTON, Trans. Am. Ent. Soc., n, p. 234, 1868. This species is also widely distributed and abundant and is gener- ally found in company with the preceding. The fifty specimens in the collection were taken at Fox Point, Berg Bay, Sitka, Yakutat, Sal- dovia, Kadiak, Kukak Bay, and Popof Island. The male differs con- siderably from the female in coloration ; the abdomen in the former sex is reddish yellow above with black markings on the basal plates and first segment, the venter of the abdomen is white at base, becom- ing reddish towards tip, and the pectus is yellowish white. IO2 KINCAID [362] TENTHREDO MELLINA. Tenthredo mellina NORTON, Bost. Jour. Nat. Hist., vn, 2, p. 254, 1860. Three females, Popof Island. Taken on the flowers of Heracleum lanatum. TENTHREDO EVANSII. Tenthredo e-vansii HARRINGTON, Can. Ent.,xxi, p. 78, 1889. (Tenthredopsis.) Five females and four males, Sitka, June 16; Yakutat, June 21 ; Saldovia, July 21 ; Kadiak, July 20; Virgin Bay, June 26. This is a very variable species, the amount of black pigment on the dorsulum of the abdomen varying considerably. The female in some of its va- riations resembles Tenthredo californica Norton, but the males are extremely different ; in californica the latter sex has the dorsal surface of the abdomen almost entirely black, while in evansii the correspond- ing region is yellowish green with a variable narrow band across each segment. TENTHREDO LINEATA. Tenthredo lineata PROVANCHER, Natural. Canad., x, p. 198, 1878. Three females, Sitka, June 16; Virgin Bay, June 26; Gustavus Point. Previously known from Canada, Colorado, and New Hamp- shire. TENTHREDO FLAVOMARGINIS. Tenthredo flavomarginis NORTON, Bost. Jour. Nat. Hist., vii, 2, p. 254, 1860. Five females and one male, Berg Bay, June 10; Yakutat, June 21 ; Saldovia, July 21. The male resembles the female except in the nar- rower form of the body and in the presence of three reddish-brown spots on the dorsum of the abdomen. This species was originally described by Norton from Connecticut, but is also known from Col- orado. TENTHREDO NIGRICOLLIS. Tenthredo nigricollisY>.\KS>\, List, Hym. Br. Mus., I, p. 308, 1882. Three females and one male, Sitka, June 16; Saldovia, July 21; Kukak Bay, July 4. This species was originally described by Kirby from Newfoundland, and is also recorded from New Hampshire. The male differs from the female in the narrower form of the body and in the presence of several pale-brown spots on the upper surface of the abdomen ; it agrees very closely with the male described by Mr. Harrington as Tenthredo semicornis (Can. Ent., xxi, p. 98, 1889), and may prove to be identical with it. [363] THE TENTHREDINOIDEA IO3 TENTHREDO ERYTHROMERA. Tenthredo erythromera PROVANCHER, Addit. Faun. Canada, Hyme'n., p. 13, 1885. Ten females, Sitka, June 16; Metlakahtla, June 4; Muir Inlet, June 10 ; Saldovia, July 21 ; Kukak Bay, July 4; Yakutat, June 21 ; Kadiak, July 4. This species was described by Provancher, from Vancouver Island, but it also occurs in Colorado and Washington. The specimens in the collection vary but slightly, except in the colora- tion of the labrum and clypeus, which range from almost pure yellow to black. TENTHREDO MELANOSOMA. Tenthredo melanosoma HARRINGTON, Can. Ent., xxvi, p. 194, 1894. Six females and one male, Sitka, June 16; Saldovia, July 21; Yakutat, June 21 ; Kadiak, July 20. This species was described by Mr. Harrington, from Fort Wrangell, Alaska. The male resembles the female, except in the narrower form of the body and in the pres- ence of three brown vittae on the dorsulum of the abdomen. TENTHREDO HARRIMANI sp. nov. Female: Black with the following parts ferruginous: Antennae, spot externally on jaws, tegulae, all of legs beyond trochanters, varia- ble obscure spots on disc of third, fourth, and fifth tergal segment of abdomen ; clypeus, labrum, base of mandibles, spot between antennas, narrow line at lower margin of eyes, posterior angles of pronotum, and small circular spot above posterior coxae, yellow ; clypeus squarely and deeply emarginate with the lobes obliquely truncate ; antennae with the third joint one-quarter longer than the fourth ; wings yellowish hy- aline, nervures brown, stigma pale brown.

Color black, with the following parts yellow : Labrum, clypeus, base of mandibles, ventral angles of pronotum, spots on dorsal angles united by a slender line, spots above middle and pos- terior coxae, band across posterior margin of basal plates; narrow line across posterior margin of dorsal abdominal segments three, four, and five; row of large spots along outer margins of venter; small [365] THE TENTHREDINOIDEA IC>5 spots at apex of coxae, anterior surface of fore and medial femora band on basal two-thirds of posterior femora, tibiae except small spot at apices, tarsi except spots above ; wings hyaline, nervures and stigma. Male: Length 10.5 mm.; body narrower than in the female; sculptured and colored as in female, but the spots on the prono- tum are reduced or absent, the band on the basal segment is wanting, venter entirely yellow, coxae yellow, femora, tibiae, and tarsi black above yellow beneath ; posterior tarsi entirely black. Two females and four males, Popof Island, July 14. Type no. 5309, U. S. National Museum. Taken upon the flowers of Heracleum lanatum. Family CIMBICID^. CIMBEX AMERICANA. Cimbex americana LEACH, Zool. Miscell., in, Tab. 61, 1817. A single specimen captured on Kadiak Island by Mr. L. Cole. This is a variety of this variable species in which the body is entirely blue-black, white maculations being entirely absent, and the wings are clear with some yellow spots along nervures. TRICHIOSOMA TRIANGULUM. Trichiosoma triangulum var. aleutiana CRESSON, Trans. Am. Ent. Soc., viu, p. i, 1880. Five specimens from Kukak Bay, Kadiak Island, and Popof Island. The specimens agree perfectly with those of the above species in the collection of the American Entomological Society. THE SPHEGOIDEA AND VES- POIDEA OF THE EXPEDITION (107) The following report on the Sphegoidea and Vespoidea of the Ex- pedition, by Prof. Trevor Kincaid, was originally published in the Proceedings of the Washington Academy of Sciences, vol. n, pp. 507— 510, Dec. 20, 1900. It is here reprinted from the same electrotype plates, so that it may be quoted exactly as if it were the original. The original pagination has been preserved and transferred to the inner or hinge side of the page, where it is enclosed in brackets, thus [508] ; while the consecutive pagination of the present volume has been added in the usual place.

EDITOR. (108) THE SPHEGOIDEA AND VESPOIDEA BY TREVOR KINCAID THE collection upon which this report is based is a small one, including but nine species, but it is of considerable interest from the fact that but a single representative of the above groups has been recorded from Alaska, namely Dolichocrabro ivickhami Ashmead,1 which was collected by Mr. H. F. Wickham at Fort Wrangell. At the same time and place Mr. Wickham cap- tured a Pemphredonid which Mr. Ashmead determined as Pas- salcecus cusptdattis Smith. In the collection of the U. S. National Museum there is also a Chrysid collected at Fort Yukon by Mr. L. M. Turner in 1877. This has been determined by Mr. Ashmead to be Omalus sinuosus Say. These three species, to- gether with those listed below, bring the total number of known Alaska forms up to twelve. It is evident that the coastal regions of Alaska do not afford a favorable environment for either fossorial Hymenoptera or wasps. 1 Synopsis of the superfamily Sphegoidea, Can.

Male : Dorsal region of head closely and distinctly punctured, with- out any signs of striae ; cheeks with very faint punctures ; clypeus and face with a silvery gray pile ; head and thorax with long gray hair, most evident on the pleurae and middle segment; clypeus obtusely bidentate ; dorsulum with distinct separated punctures, striate behind ; mesopleurae very delicately striated, with no evident sign of punctures ; middle segment coarsely rugose-reticulate, with a triangular smooth space at base, posterior surface depressed medially, the central area bounded by distinct but irregular ridges; sides with indistinct and father irregular striae. Color black; calcaria and tarsi testaceous. Length 7 mm. Three males, Fox Point, Alaska, July 28. Type. — Cat. no. 5314, U. S. National Museum. This species is closely allied to Mimesa mixta Fox, which is re- corded from California, Oregon, and Washington, but a comparison [509] THE SPHEGOIDEA AND VESPOIDEA III with the types of the latter species in the collection of the American En- tomological Society leads the writer to the conclusion that the northern form is distinct, since in M. mixta the antennae and petiole are both shorter, the posterior face of the middle segment is not depressed and the smooth area at the base is lacking ; also the front of the head is striato-punctate, which is not the case in the new form. VESPOIDEA. Family POMPILIIXE. Arachnospila septentrionalis sp. nov. Female : Black ; first and second segments of abdomen sanguineous except the extreme base of first segment and narrow apical margin of second, which are black; head broader than thorax, smooth, with in- distinct, widely separated punctures; vertex and front sparsely clothed with long black hair, a greater abundance of the same on the cheeks ; eyes separated from the mandibles by a narrow margin, converging but little above, the space between them equal to one and one-half times the length of the first joint of the flagellum ; space between hind ocelli a little less than that between them and nearest eye-margin; clypeus very slightly emarginate, almost truncate, the lateral anterior angles rounded and the anterior border finely margined ; antennae slender, nearly as long as head and thorax, first joint of flagellum longer by one-fourth than the second ; pronotum angulate behind ; scutellum flatly convex in the center, declivous at the sides ; middle segment strongly rounded out, smooth, with a faint trace of a medial groove; medial and posterior tibiae and tarsi with numerous spines outwardly ; anterior tibiae and tarsi with a row of spines along outer margin ; tarsi coarsely ciliated beneath ; inner spur of hind tibiae two- thirds the length of the first tarsal joint; claws with a sharp median tooth ; abdomen elongate-ovate, as long as the head and thorax ; wings fuliginous; third submarginal narrowed about one-fourth on upper margin, the third cubital nervure curved outwardly; second submarginal of nearly the same shape and slightly smaller than the third submarginal, the first cubital nervure curved toward the base of the wing; first recurrent nervure received a little beyond the middle of the second submarginal ; second recurrent received before the mid- dle of the third submarginal cell.

("4) FORMICID^ OF THE EXPEDITION BY THEODORE PER6ANDE THE present paper is based upon a small collection of Alaska Formicidae, made by Professor Trevor Kincaid while connected with the Harriman Expedition during the summer of 1899, and is especially interesting on account of the close relationship of most of the species to those of our northwestern States. Subfamily CAMPONOTINI. Formica neorufibarbis Em. Formica neorufibarbis EM., Zool. Jahrb. Jena, p. 660, 1899. The series representing this species are all workers, and were ob- tained in the following localities: Sitka, i specimen; Metlakahtla, 5 specimens ; and Kadiak, 34 specimens. Those from the latter lo- cality were found in a rotten log. The species is quite variable as to coloration; the palest forms, from Metlakahtla, are absolutely identical with those found in Colo- rado, Dakota, and Oregon, while the darker specimens agree more or less closely with forms occurring in Colorado, Utah, and some of the far northwestern States. Lasius niger L. subsp., sitkaensis subsp. nov. Worker: Length about 4 mm. Head and abdomen dark brown, the posterior edge of the abdominal segments whitish or more or less ("5) H6 PERGANDE [52°] distinctly yellowish or greenish in a certain light, front of head as far as the eyes, the clypeus, cheeks, and under side of the head, sides of the thorax, the antenna and legs, lighter or darker ferruginous ; apex of the joints of the flagellum dark brown ; mandibles red, their ex- ternal edge and the teeth, as well as the eyes, black ; palpi yellowish. Appressed pubescence yellowish and rather dense on the head and ab- domen; erect hairs quite profuse, yellowish or brownish in certain lights ; those of the clypeus, the under side, and end of the abdomen much the longest ; there are but a few erect hairs on the scape, the femora and tibiae. Punctuation of the head, thorax, and abdomen minute and dense, those of the mandibles rather coarse. Scale stout, its upper edge arcuated. This ant, as far as I have been able to ascertain, does not agree with any of the various forms comprising the group L. niger, which have thus far been described, but appears to be nearest related to one of the forms of Lasius subniger, inhabiting Maine, though it is almost twice as large and much darker and with the eyes more elongated ; the general appearance of this ant is very similar to that of Lasius aliena. Twenty-five specimens, taken at Sitka during June. Type. — Cat. no. 5277? U. S. National Museum. Subfamily MYRMICINI. Leptothorax yankee Em. var. kincaidi var. nov. Female : Length about 4 mm. Head and thorax black, the abdo- men dark brown, with the posterior edge of the segments brownish yellow; antennae, mandibles, and legs yellowish red, the neck and paler parts of the nodes of a darker red ; the flagellum grows gradu- ally darker towards the end, with the last joint black; femora dark brown, their base and apex yellowish red; teeth of mandibles black. Head finely striated, the striae most distinct in front of the eyes and between the frontal carinae ; the posterior half of the head is finely and rather densely rugose or reticulate, the clypeus is almost smooth and the mandibles striato-punctate; pronotum and mesonotum quite coarsely rugose, the metanotum, scutellum and upper surface of nodes finely, though rather indistinctly, striated; declivity of the metathorax transversely striated. Abdomen smooth. Erect hairs short, truncate and pale yellowish, those of the nodes and abdomen longest; there are also a few much finer, erect hairs on the femora. The female resembles somewhat that of L. yankee, which, how- ever, is somewhat smaller, the last antennal joint arid metanotal spines [52l] FORMICID^E 117 shorter, the hairs of the abdomen much finer and the erect hairs of the femora wanting. Worker: Length about 3 mm. Head and teeth of mandibles black, the abdomen dark brown ; antennae, mandibles, thorax, legs and nodes reddish yellow ; coloration of the last three or four joints of the antennae and the femora as in the female, the upper surface of the thorax and nodes more or less decidedly reddish brown. Striation of the head more distinct than in the female, and the space between the striae more or less distinctly reticulated, particularly so towards the sides. Pronotum and mesonotum and the nodes finely rugose ; sculp- turing of the metanotum slightly coarser. Abdomen smooth ; all the hairs similar to those of the female. The worker is very similar in appearance to those of L. yankee, though somewhat larger, more robust, the sculpturing coarser and the hairs stouter. One female and twelve workers, taken at Metlakahtla in June. Type. — Cat. no. 5278, U. S. National Museum. Myrmica sabuleti Meinert, var. lobifrons var. nov. Worker : Length about 3 mm. Color dark brown or black ; mandi- bles, antennae, legs, sides of the thorax and of the abdomen more or less distinctly yellowish brown, reddish brown, or almost black. This variety is closely related to a form of Myrmica sabuleti in- habiting South Dakota, but is somewhat larger and much darker, with the sculpturing of the head and thorax coarser and the hairs stouter and shorter.

ALASKA has long been a terra incognita to the Hymenopterol- ogist. Up to the year 1899, the date of the Harriman Expedi- tion, less than 30 species of Hymenoptera were known from this vast territory. [117] 124 ASHMEAD In this paper 335 species are recorded, of which number 201 are regarded as new to science and are here first described. Of the 10 superfamilies, into which the order is now divided, all are represented in Alaska and are distributed into 29 families and 183 genera. Two of these genera, Dallatorrea and Hypo- syntactus are new, and of the remainder, thirty have not been previously reported from North America. This sudden and great increase of our knowledge in this field, in so short a time, is due mainly to the Harriman Expedition and to its indefatigable collector, Professor Trevor Kincaid. The distribution of some of the species taken is most inter- esting. Four species, namely, Lissonotus ruficoxis Schmieds- knecht, Triclistus curvator Fabricius, Alysia manducator Panzer and Ichneutes reunitor Nees, are European, and three of them have not before been reported from North America. The last two mentioned are, however, widely distributed over Europe from the Arctic to the Mediterranean, and will doubtless be found to occur in Asia also. Alysia manducator is parasitic upon dipterous larvae (Muscidce}, while Ichneutes reunitor de- stroys the willow saw-flies (Nematida). Two bumble bees, Bombus ^pleuralis Nylander and B. mela- nopygus Nylander are Asiatic occurring in Siberia. Bombus moderatus Cresson is also recorded from Bering Island off the coast of Asia. Others of the bees taken occur in British Columbia, Hudson Bay Territory and in some parts of the northwestern States, i. e., Washington, Oregon, California and Utah ; only a few extend their range into the mountains of New Mexico, Idaho, and Colorado. A similar distribution is ob- served in some of the Sphecoidea and Vespoidea. The ant, Myrmica lavinodis Nylander is found in Europe and in Asia — Turkestan and Siberia; and another species, Lasius niger Linne, is found in Europe, northern Africa, Japan and Asia. In the Ichneumonoidea and the Tenthredinoidea, many of the known species have a wide distribution throughout the Boreal Zone, i. 1854. — CRESSON, Proc. Ent. Soc.

This species is also common in Vancouver Island, B. C. The type of Bombus lacustris Cresson was submitted to me for examination, together with other of Cresson's types of bumble bees, by Dr. Henry Skinner, Curator of the American Entomological So- ciety, and it is undoubtedly identical with the above species. What Handlirsch describes as Bombus ternarius var. lacustris is probably a different species. BOMBUS ALASKENSIS sp. nov. Female. — Length 17 mm. Resembles B. melanopygus Nylander, very closely and with the color of the pubescence almost identical, ex- cept that the scutellum is more grayish and the first and second dorsal abdominal segments are clothed with a yellowish pubescence, the third and fourth red or fulvo-rufous, the fifth and sixth black. Worker. — Length 12 to 13 mm. Colored as in female and prac- tically the same except in being much smaller. Male. — Unknown. Type. — Cat. No. 5720, U. S. Nat. Museum.

Malar space a little longer than wide. First joint of flagellum a little longer than the third, the second hardly longer than thick and only about two-thirds the length of the third. Worker. — Length (major) 12 mm. ; (minor) 7«5 t° 10 mm. Both colored as in female, except that the pubescence on the face in the worker minor is black or with only a few whitish hairs intermixed with the black. Male. — Unknown . Type. — Cat. No. 5721, U. S. Nat. Museum. From Popof Island, June 21 ; Yakutat, June 21 ; Virgin Bay, June 21 ; Fox Point, July 20. BOMBUS DIMIDIATUS sp. nov. Female. — Length 12 mm. Mesopleura, the anterior part of the thorax above, the apex of scutellum and the dorsal abdominal seg- ments i and 2 clothed with a pale yellowish pubescence that on the pleura is nearly white, on the anterior part of the thorax and the scutellum mixed with black hairs on dorsal segments i and 2 inter- rupted by a bare space medially ; otherwise, except some pale hairs on the middle of the face and the apical fringe on the ventral segments, the pubescence is black. Wings fuscous. Malar space about one- third the length of the eye. First joint of flagellum nearly as long as 2 and 3 united, the second shorter than the third, not longer than wide. Occasionally the black hairs on the apex of the third and fourth dorsal segments of abdomen are well mixed with fulvo-rufous hairs, having the appearance of two red lines across the black pubescence. Worker. — Length 9 mm. Agrees in color with the female (or? worker major) , except that the face is usually black or with only a small tuft of pale hairs between and extending below the insertion of the antennae. 136 ASHMEAD [I3°] Male. — Unknown. Type. — Cat. No. 5722, U. S. Nat. Museum. From Fox Point, July 28; Wrangell (H. F. Wickham). The female described above may really be the worker major, for many of our bumble bees have two forms of workers — a worker major and a worker minor. Family PSITHYRID-E. Genus Psithyrus Lepeletier.
