The few species of this genus thus far known in our fauna have the funic- ulus of the antenna) 7-jointed, with the exception of 7'. setosm, which may perhaps be hereafter recognized as generically distinct; they resemble in form Ventrinus, though the contiguous front coxffi and toothed claws will enable them to be immediately distinguished. It is worthy of remark that the first observation concerning the anal seg- ment of the ^, is recorded by Mr. Brisout de Barneville.* Had the impor- tance of this observation been recognized, and its limitations inquired into, much of the labor 1 have devoted to the study of the llhynchoi)horous series would have been saved, and our knowledge concerning the classitieation of these insects would be much farther advanced, f Our species may be thus distinguished : Surface clothed with scales and pubescence 2.
