CEdionychis 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-
