Long. 2-2-2 mm. 



Hah. Ceylon, Dikoya. Several specimens. 



The frontal area has, in addition to the marginal hairs, a 

 very short pubescence in some examples, probably a sexual 

 character. The prothorax is gently curved from base to apex 

 and is slightly constricted behind the apex so as to embrace 

 the base of the head ; the punctures extend back along the 

 sides to the hinder third, and the anterior border is, in addition, 

 very finely reticulate and scantily hairy. The base of the 

 elytra is not elevated above the prothorax ; it is a singular 

 feature that of the two small cylindrical spines which occur 

 at the sutural angles of the elytra the right one is in all 

 specimens stouter and twice as long as the left.
