ITab. Ceylon, Bogawantalawa. One specimen. 



On account of the absence of distinct sutures on the an- 

 tennal chib, the comparatively long and slender scape, and 

 the slender tibiee, I am in doubt whether this species should 

 be associated with Dryocoetes. There is, however, no other 

 genus in which it can be placed, and it approximates to 

 certain species — D. dinoderoides^ Blandf., &c. — also of doubt- 

 ful systematic position, from Japan. 



Its generic characters require to be fully ascertained by 

 dissection.

Ilab. Ceylon, Dikoya. One example. 



This species is distinguishable by the finely asperate hinder 

 half of the subglobose j)rothorax, the uniseriate punctures of 

 the elytral interstices, and tiie convex declivity, which is 

 impressed along the suture and bitubcrculate on each side.
