The publication of the series of volumes on the Harriman Alaska Expedition of 1899, heretofore pri- vately printed, has been transferred to the Smithsonian Institution by Mrs. Edward H. Harriman, and the work will hereafter be known as the Harriman Alaska Series of the Smithsonian Institution. The remainder of the edition of Volumes I to V, and VIII to XIII, as also Volumes VI and VII in preparation, together with any additional volumes that may hereafter appear, will bear special Smithsonian title pages. SMITHSONIAN INSTITUTION, WASHINGTON, D.C., Jury, 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 PREFACE Ir 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, Formicide, 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. - ©. Hart Merriam, Editor. WasHincTon, D. C., May 1, 1903.

Popo Island, Shumagin cep sxsoon:ntenthtsniensiics Broatiaplocs (ix) eet IPTERA OF THE EXPEDITION The following paper on the Diptera of the Expedition, by D. W. Coquillett, Division of Entomology, U. S. Department of Agriculture, was originally published in the Proceedings of the Washington Acad- emy of Sciences, vol. 1, 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. 1x. Ento- mological Results (3): Diptera. No other alterations have been made. Since the original publication of this paper the author has described as new, under the name Szmulium 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 : Page 5 [391]: Eighteenth line from bottom, enclose ‘ Meigen’ in parentheses. Seventeenth line from bottom, for ‘ Anaclinia’ read Mycetophila. Page 8 [394]: Twelfth line from bottom, enclose ‘ Linné’ in parentheses. Eleventh line from bottom, change ‘ Scatopse’ to Zipula. Page 10 [396]: Eleventh line from bottom, enclose ‘ Fabricius ’ in parentheses. Tenth line from bottom, change ‘ Ceratopogon’ to Chironomus. Page 13 [399], fifth and fourth lines from bottom, change ‘ disphana’ to diaphana. Page 19 [405], fourth line from bottom, for ‘ Pachyrrhina’ read Pachyrhina. Page 20 [406]: First line, for ‘ Xylophagide’ read Leptide. Sixteenth line from bottom, for ‘ Stratiomyiide’ read Stratiomyide. Page 21 [407], twentieth line from bottom, for ‘Empidide’ read Empide. Page 55 [441], thirteenth line from bottom, for ‘Anthomyiide’ read Antho- myid@. Epiror. (2) DIPTERA OF THE EXPEDITION BY D. W. COQUILLETT Tue 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 [390] 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 Tipulidz, the most interesting addition to our genera is the genus Te/matogeton, of the family Chirono- mide, heretofore known only from St. Paul Island, in the Indian Ocean. Family MYCETOPHILIDA. Diadocidia borealis sp. nov. Head and antenne 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 ; coxe and femora light yellow, tibiz 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. Hlesperinus brevifrons WALKER, List Dipt. Ins. British Museum, 1, p. 81, 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 Hesferinus has heretofore been placed in the family Bibionidz, but it differs from all the other members of that family by the elongated antennz. In this and other structural char- acters it agrees very well with the members of the present family. [392] ; DIPTERA 5 Necempheria kincaidi sp. nov. Head and its members black, second joint of antenne 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 vitte, scutellum black, the base narrowly yellow, its hairs and those of the thorax golden yel- low; abdomen brownish black, slightly polished, its hairs yellowish ; coxe and femora yellow, tibiz 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. Length6 mm. A female specimen, collected July 8. HTabitat.—Popof Island, Alaska. Type.—Cat. no. 5191, U. S. National Museum. Readily distinguished by its venation from any of the described species. Respectfully dedicated to Professor Trevor Kincaid, whose extensive captures have added so much to our knowledge of the fauna of this interesting region. Anaclinia nemoralis Meigen.
