Genus Tipula Linnaeus. 



Tipula hinei, sp. n. 



Generally similar to T. centralis Loew; antennae bicolorous; meso- 

 notum light brown, the prsescutum with three clear gray stripes that 

 are narrowly margined with brown, the median stripe split by a cap- 

 illary brown line; male hypopygium with the ninth tergite as in cen- 

 tralis, the U-shaped posterior notch much wider. 



Male. — Length 16.5 mm.; wing, 17.6 mm. 



Female. — Length 22 mm. ; wing, 17 mm. 



Frontal prolongation of the head brown, sparsely pruinose; palpi 

 brown. Antennse with the basal three segments yellow, the flagellar 

 segments distinctly bicolorous, the basal enlargement conspicuous, 

 black, the remainder of the segments brownish yellow; distal flagellar 

 segments shghtly more unicolorous. Head light gray, paler adjoining 

 the inner margin of the eye; a narrow, indistinct, capillary line that is 

 impressed on the vertical tubercle. 



Mesonotal prsescutum light brown, the region before the pseudo- 

 sutural foveee more grayish; three clear gray stripes that are narrowly 

 margined with brown, the median stripe split by a capillary dark brown 

 line that broadens out slightly behind; scutum dull gray, each lobe with 

 two clearer gray areas that are encircled by brown ; scutellum and post- 

 notum gray with a narrow brown line. Pleura dull gray. Halteres dark 

 brown. Legs with the coxae faintly gray pruinose; trochanters brown- 

 ish yellow; femora pale brown, more yellowish basally, the tips narrowly 

 brown; tibiae and tarsi brown. Wings of the type of T. septentrionis 

 Loew and related species, whitish sub hyaline with a heavy brown and 

 gray clouded pattern. 



Abdomen brown, the basal tergites paler, the segments pale lat- 

 erally; sternites pale reddish brown. Male hypopygium as in T. cen- 

 tralis, the ninth tergite as in this species but the median notch broadly 

 U-shaped, the adjacent angles subacute. Ninth pleurite small, complete 

 or nearly so; outer pleural appendage rather small, pale basally, cov- 

 ered with a dense pale pubescence and rather long black setae; inner 

 pleural appendage compressed, the caudal margin roughened and 

 blackened. Ninth stemite profoundly incised beneath. Eighth stemite 

 unarmed. 



The feiuale is generally similar to the male but the wing-pattern 

 more tesselated with white. Abdominal tergites biiff with three con- 

 spicuous brown stripes, the lateral margins conspicuously light gray. 

 Ovipositor and dorsal shield shiny dark brown; lateral margins of the 

 tergal valves with comparatively few (about ten) blunt teeth. 



Habitat. — Alaska.
