198 THE CANADIAN ENTOMOLOGIST 



unarmed. Eighth tergite, except at the ends, concealed beneath the seventh 

 tergite. 



Habitat. — California. 



Holotype. — cf, Alta Meadow, Sequoia National Park, California, altitude 

 9,000 feet, Juljy 19, 1907, (J. Chester Bradley). 



The type is in the collection of Cornell University. 



This primitive liittle Tipiila bears a certain resembrance to T. coracina 

 Al|ex. of Alaska, and the two probably belong to the same group of the genus. 

 The type of T. plutovis \\a.s sent to Prof. Doane for comparison with his types; 

 he notes the general resemblance of the species to T. spernax O. S., to which, 

 however, the species is at most distantly related. The fused hypopygium of 

 T. spemax with a broad, median tergal lobe will easily separate the species 

 from any other similar member of the genus. 

 Tipula s,hasta, new species. 



Belongs" to the angustipennis group, close to T. angiistipennis Lw., but 

 with the thorax darker colbured, the wings of a very decided reddish yellow 

 tinge, the abdomen without a black dorso-median stripe, and the details of the 

 male hypopygium different. 



Male. — Length 20-21 mm.; wing 17-18 mm. 



Frontal prolongation of the head black, moderately elpngated, the nasus 

 distinct; mouth-parts black. Antenna? with the first segment black; the second 

 segment and basal two-thirds of the first flageljlar segment pale brown to almost 

 black; remainder of the antenna? black; flagellar segments with the basal swelling 

 moderate in size. Head broad, genae swollen, eyes small. Head dark brown 

 with a very narrow, pale, whitish yellow line surrounding the eyes. 



Mesonotal prsescutum buffy, more dusky anteriorly, clearer near the suture; 

 pra?scutum with four very distinct, dark brown stripes, the median pair long, 

 slightly narrowed behind, separated from one another by a more or less distinct 

 capillary line; the Ijateral stripes, and, less distinctly, the median stripes, are 

 surrounded by a narrow, intensely black border; scutum buffy, the lobes dark 

 brown, surrounded by narrow, black margins; scutellum with three blackish 

 lines; postnotum dark. Pleura dark brown, indistinctly blotched with still 

 darker markings. ' Halteres orange, the knobs and terminal portions of the 

 stem dark brown. Legs with the coxa? grayish brown; trochanters brown, 

 femora reddish with the tips narrowly dark brown; tibiae pale reddish, the tips 

 narrowly and indistinctly darkened; tarsi with the basal segments dull reddish, 

 gradually passing into a dark brown. Wings with a strong, saturated, reddish 

 yellow tinge, clearer, more yellow, on the costal region, especially cell Sc, more 

 brownish on the posterior portion and the wing-apex in cells Ri and Rz; stigma 

 liarge, dark brown; a small hyaline obliterative area before and beyond the 

 stigma; an indistinct hyaline line across the base of cell 1st Ah; a large pale blotch 

 toward the end of cell M, as usual in this group of species; the only nearctic 

 species of Tipula known to the writer with wings of this colour is T. ultima 

 Alex, iflavicans Fabr.) of the eastern United States. Venation: cell Mi short- 

 petiolate, the petiole a little longer than r-m; m-cu distinct or punctiform. 



Abdomen with the first segment blackish ; remainder of the abdomen 

 bright reddish, the Fhteral margins of the tergites more obscure; third abdominal 

 tergite usually a little darker in colour than the other segments. Male hypopy-
