LONGICORN COLEOPTERA FROM BURMA. 73 



This species appears to be somewhat nearly allied to Ptero- 

 lophia camura , Newm. ; but has a generally paler and more 

 uniform coloration, a more distinct dorsal carina on each ely- 

 tron, and a more parallel-sided prothorax. The disk of the pro- 

 thorax also is less convex and nearly flat; the apices of the 

 elytra are sinuately truncate, while in P. camura they are al- 

 most rounded.

By adhering strictly to the system followed by Lacordaire, a 

 new genus, in the group of the Mesosides, should be formed 

 for the reception of this species. Though it differs from all the 

 other species of Pterolophia, and indeed from all the Niphonides, 

 in having a smooth cicatrix , limited by a sharp edge , on the 

 apex of the antennal scape, yet the general ensemble of its 

 characters is such as to bring it into very close affinity with 

 certain forms of Pterolophia. It might be right perhaps to re- 

 gard it as a representative of a new genus which brings into 

 greater prominence the undoubted affinities that exist between 

 the Mesosides and the Niphonides. It seems to me to be one of 

 the faults of Lacordaire's arrangement that these two groups 

 are placed so far apart. And I also think that Lacordaire's sub- 

 division of the latter group may be improved upon by taking 

 into consideration the structure of the mesonotum. In the genera 

 more nearly allied to the Mesosides the mesonotum is pointed 

 in front and is furnished with a stridulating surface; while in
