36 THE CANADIAN ENTOMOLOGIST. 



described by Mr. Howard, have exserted ovipositors. Does this not throw 

 some h"ght on their generic position ? 



I describe below two new species belonging to Eiipebnus genus, if 

 Westwood's definition of it be correct. I must acknowledge, however, 

 that the antennge, wings and formation of thorax strikingly resemble 

 Antigaster. The exserted ovipositor would, however, easily distinguish 

 them.
