knobs darker brown; legs yellowish, tarsi and tips of femora and tibia 
brownish; abdomen brownish yellow, with a broad dorsal line and 
interrupted lateral brownish bands; posterior margin of eighth sternite 
with a cresent-shaped incision from the posterior margin of which arise 
two tufts-of rather long yellow hairs; ninth tergite with a broad, deep 
V-shaped incision the margins of which are black; ninth sternite yellow, 
with a broad, deep depression; pleural suture very short; pleura yellow, 
somewhat triangular, first pair of appendages small, spatulate, second

Habitat: Lander, Wyoming. 1 male. Alt. 5,000 to 8,000: 
Reet. 
This is the first Tipula I have seen with an open discal cell. 
As I have only a single specimen before me I do not know 
whether this is a constant character or only accidental.
