new and little-known Tipulide. 265 
again as R,; marginal cross-vein joining R, near its base ; 
R-M cross-vein distinct, but rather short ; Cu; just in contact 
with M;. Costal hump rather more prominent. 
Length of body 31 mm.; abdomen 21 mm. ; wing 24 mm. 
Breadth of abdomen 3 mm.; hypopygium 4:2 mm.; wing 
24x 7 mm. 
The wing-markings of this species resemble those of 
Tipula thibetana, de Meij., rather closely, but from de Meijere’s 
description and figures it is clear that his species is a true 
Tipula. 
Pachyrrhina citrina, sp. n. 
Head dull orange-yellow, a small vertical triangle and a

the M-—Cu cross-vein. Cell Ist M, normal, elongate, the 
cross-vein closing it joining M, a very short distance beyond 
the fork.
