1 c?; 



Nearly allied to 0. sikhimensls, Bing., but can be readily 

 distinguished from that species iiy the absence of any 

 })ubescence, the more uniform puncturation, the subtri- 

 angular second cubital cell, and smaller size. 



It has some resemblance to 0. tytides, Cam., from Sikhim, 

 but that species is not an Ancistrocents -, from 0. (Ancistro- 

 cerus) rhipheus, Cam., it differs in the pronotum, which has 

 the posterior margin more widely arched than in O. assam- 

 ensis, also the postscutellum in U. rliipheus is black and the 

 wings are darker.
