CEDIONYCHIS CINCTA. 

 PLATE XXX. FIG. 5. 



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- 

 loured, and very destructive in their habits. The 

 species named cincta is of a yellow colour on the 

 head, thorax, and scutellum. The elytra are violet 

 blue, shining, with a band of white across the mid- 

 dle, which widens at the suture. The under side 

 and antennae are pale yellowish red, the legs being 

 of a similar colour, except the hinder thighs, which 

 are bluish. It occurs in St Domingo. 



The only remaining family of the tetramerous 

 beetles that requires to be noticed, is named CLA-
