Very easily distinguishable from all the species to which 

 it is structurally a close ally by the much finer and close 

 puncturation of its elytra. The trilobed outline of the head 

 is divided, but not strongly ; the middle lobe has about two- 

 thirds the span of a lateral lobe.

This very small species is closely allied to 11. brevicomis, 

 Blackb., from which, however, it is easily distinguishable by, 

 inter alia, its elytra very evidently substriate. The trilobed
