458 Mr. W. F. Kirby on the 



Genus II. Halter. 



Halter, Ramb. Ins. NfSvr. p. 335 (1842). 



The time has hardly yet arrived for subdividing this genus, 

 to which we may provisionally refer all the transparent-winged 

 species with long beaks. The species are divisible into several 

 very distinct groups, most of which will probably hereafter 

 rank as genera. 



Section 1. 

 Hind wings linear, with a long dark band before the extremity.
