394 REVISION OF THE AMYCTBRIDES, ii. 



In the prothoracic sculpture, this species shows an approach to 

 T. catenulatus, but the elytral sculpture is closer to that of T- 

 bucephalus. As the external rostral ridges are continuous along 

 head, I prefer to regard this species as belonging to the typicus- 

 group, though the internal ridges are not prominent. Probably 

 the discovery of a male would decide its true position; but the 

 species is so distinct, that I have not hesitated to describe it on 

 a single female.
