PLATE XXX. Fig. 5. 
(Edionychis is one of the sub-genera into which 
the extensive genus Haltica of Linnaeus has re- 
cently been divided. The species are distinguish- 
ed from most other tetramerous beetles, by the 
thickened hinder thighs, by which they are enabled 
to leap to a considerable height into the air. Most 
of them are of small size, but they are finely co-

The only remaining family of the tetramerous 
beetles that requires to be noticed, is named Cla-
