and it is I apprehend amongst these, in the neighbourhood of 

 Trogosita, Cucujus and Passandra, that we must look for the 

 natural situation of the genus before us. From Trogosita it is, 

 however, distinguished by the bilobed maxilla, the elongated lobes 

 of the labium, the filiform antennse, and the 5-jointed tarsi. In se- 

 veral of these respects it approaches much nearer to the Cucujidce. 

 The remarkably long setae with which the sides of this insect 

 are furnished seem to indicate some peculiarity in its habits with 

 which we are unacquainted. Such setae appear in some groups, 

 especially the Geodephagous Coleoptera a.nA¥os&o\\a\ Hymenoptera, 

 to be accompanied by very predaceous habits, and, judging from 

 the powerful mandibles of the insect before us, I should not be 

 surprised if such are the habits of this insect.
