 fortiores spinuloses. Tarsi breviores. Prosternum carinatum. 

 In praecedentium societate frequenter lectum. 



This is perhaps the prettiest of the five species of the family 

 just described^ and at first sight recognised by the shape of its 

 body and the polished back. The head is very large. The 

 thorax is narrowed in front and behind, at the latter place 

 impressed with four deep not to be overlooked punctures. The 

 wing-covers are oval, a little inflated about the middle, rounded 

 at the apex and longer and wider than the abdomen. The 

 prosternum is carinated. 



It affords me much gratification to be enabled to publish 

 representatives of three genera of this highly interesting and 

 probably very extensive and widely distributed family of 

 pygmies, the South Asiatic representatives of which have 

 hitherto been entirely unknown. I have no doubt that even 

 this Island is the abode of a great many more species.

This as well as the following species belongs to Erichson's 

 division II. B. of the g., both having the abdomen immarginate 

 and the 4th tarsal joint bilobed. Every thing about this 

 species is elongated. The head is about one third broader 

 than the thorax, the forehead is slightly excavated with two
