In direct opposition to the mode of sitting of tlie insects of I be 

 principal genus of the preceding family, which may be said to 

 sit on their heads, the species of this family sit on their tai/s, 

 liaving the head considerably raised from the surface on which 

 they repose, tlie anterior pair of legs being ])ut forward, the mid- 

 dle pair rather stretched out sideways, and the j)osterior pair 

 placed close beside the abdomen; by this pecnliarily any species 

 of this family may be immediately recognized if seen at rest. 



The three genera of this family may be at once distinguislied 

 as follows : — 



a. Head smooth. 



I). Second joint of labial jialpi with no projecting tuft. 1. Gkaci-
