Bathypogon, Loew. 



This genus is distinguished by having the vein closing the 

 fourth posterior cell almost in a line with that closing the 

 discal cell, also by the short wings. It is allied to Stenc- 

 pogon, but the face is much broader than in that genus. 

 The Australian species are nearly allied; they are best dis- 

 tinguished bv the colour of the legs and bristles.
