LIST OF DIPTERA. 



In this genus, of which Trupanea is a subgenus or group, the 

 veins of the wings differ much in structure from those of the other 

 Asilites and of the Dasypogonites and Laphrites. The veins are 

 equal in number to those of the other Asilida?, but the radial vein is 

 forked at more or less before half its length, and the cubital is 

 simple.
