transverse rugosities which diminish gradually towards the apex. 

 Breast metallic green ; rest of the underside and the legs fulvous. 



Length 7 mm. 



Hab. India. 



Although I have only seen a single female specimen of this 

 species, the differences in the sculpturing and coloration are so 

 marked that it cannot easily be confounded with any other of its 

 allies ; the short and very strongly punctured thorax and the 

 rugosities of the elytra, which resemble those of the genera Edusia 

 and Abirus, instead of the usual irregular rough appearance, will 

 at ouce distinguish this species.
