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 coxe brown on 
the outer face; trochanters dull yellow; femora and tibie 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 R445, along the outer 
end of cell 7st 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 R2 slightly oblique, inserted in RJ rather far before its 
tip, so that R/+R2 is greater than the deflection of R2 alone; petiole of cell R# short, 
about one-fourth longer than r-m,; r-m inserted between R4#+5 and M1+2; petiole 
of cell M7 longer than this cell. 
Abdomen dark brown; valves of the ovipositor reddish brown, strongly com- 
pressed, slightly upcurved at the tip. 
Habitat.—Oregon. 
Holotype, 2, 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. septentrionalis Bergr. (Alaska) in its spotted ‘wings 
but may be distinguished by the colorational and venational details as described above. 
Subfamily Tipuline. 
Genus Tipula Linneus. 
Tipula mallochi, sp. n. 
Belongs to the submaculata group; close to T. submaculata Lw.; male hypopygium 
with the horns of the tergite short, outer pleural appendage not bifid, gonapophyses 
short, eighth sternite with two powerful decussate bristles. 
Male.—Length, 15 mm.; wing, 17—17.4 mm. 
Female.—tLength, 20 mm.; wing, 18.5—19 mm. 
Frontal prolongation of the head brown, more yellowish above; palpi pale brown. 
Antenne 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 prescutum 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 coxe pale whitish 
yellow; trochanters yellow; remainder of the legs darker. Wings pale gray, the 
base of the wings and the costal region more yellowish; stigma brown; a brown 
cloud at the origin of the sector; tip of the wing indistinctly darkened; obliterative 
area before the cord in the base of cell R2. 
Abdominal tergites dull brownish yellow, on the sixth to ninth tergites dark 
brown; the caudal margins narrowly, the lateral margins more broadly, silvery;
