appearance from those of the preceJing group. The head, 

 instead of being small is rather large and very coai'sel_y 

 punctate, the ])rothorax being sliglitly elongate and rather 

 strongly narrowed from apex to base; the elytra are equal 

 in length to the ])ronotum in the male and slightly shorter 

 in the female, with the sides strongly divergent ])osteriorly, 

 having the surface depressed and ver}^ coarsely punctate.
