lary line that is more distinct in front; the sides of the median stripe are nearly par- 

 allel; lateral stripes narrow, their anterior ends subacute; scutum with the lobes 

 marked with brown; scutellum light gray. Pleura dark brown, gray pruinose. 

 Halteres pale yellowish brown, the knobs dark brown. Legs with the coxae brown on 

 the outer face; trochanters dull yellow; femora and tibise dull yellow, tipped with 

 dark brown; tarsi dark brown, the base of the metatarsi paler. Wings subhyaline, 

 the costal and subcostal cells more yellowish; stigma oval, dark brown, paler 

 distally; sparse brown clouds along the cord, at the fork of R-f-\-5, along the outer 

 end of cell 1st M2 and, less distinctly, at the base of the sector; veins dark brown, Sc 

 more yellowish. Venation: The distance between Sc2 and the origin of the sector 

 shorter than the straight portion of the sector alone; Rs angulated and spurred at its 

 origin; upward deflection of /?/ slightly oblique, inserted in Rl rather far before its 

 tip, so that Rl-\-R2 is greater than the deflection of R2 alone; petiole of cell R4 short, 

 about one-fourth longer than r-m; r-m inserted between R4-\-5 and Ml-\-2; petiole 

 of cell Ml longer than this cell. 



Abdomen dark brown; valves of the ovipositor reddish brown, strongly com- 

 pressed, slightly upcurved at the tip. 



Habitat. — Oregon. 



Holotype, 9, Hillsboro, April 1, 1919 (F. R. Cole). 



Paratype, 2, Corvallis, May 14, 1917 (Moulton). 



The type is much larger than the paratype but undoubtedly refers to the same 

 species. The fly is closest to T. septentrionnlis Bergr. (Alaska) in its spotted wings 

 but may be distinguished by the colorational and venational details as described above. 



Subfamily Tipulinse. 

 Genus Tif<ula Linna;us.

Belongs to the submaculata group; close to 7". submaculata Lw. ; male hypopygium

Male. — Length, 15 mm.; wing, 17 — 17.4 mm. 



Female. — Length, 20 mm.; wing, 18.5 — 19 mm. 



Frontal prolongation of the head brown, more yellowish above; palpi pale brown. 

 Antennae bicolorous, the flagellum with the basal enlargement of each segment black, 

 the remainder light yellow, on the apical segments a little more infuscated. Head 

 yellowish brown with a sparse grayish bloom; a capillary dark brown median line. 



Mesonotal prasscutum dull brownish yellow with four rather narrow reddish 

 brown stripes, the remainder of the dorsum yellowish. Pleura pale yellow, whitish 

 pollinose. Halteres pale, the knobs dark brown. Legs with the coxae pale whitish 

 yellow; trochanters yellow; remainder of the legs darker. Wings pale gray, the

 cloud at the origin of the sector; tip of the wing indistinctly darkened; obliterative 

 area before the cord in the base of cell R2.

 brown; the caudal margins narrowly, the lateral margins more broadly, silvery;
