SPHINDIDAE CIOIDAE TENEBRIONIDAE. 



1 I have not studied critically the species of this family, and the list is simply a compilation: 

 there are many species in my collection which have not yet been identified. 



2 Cis thoracicornis Ziegl. Proc. Ac. Nat. Sc. Phila. 2, 270, helongs to this genus, but the description 

 does not enable it to be identified. 



3 The arrangement here adopted is somewhat different from that which is set forth in Classification 

 of Coleoptera of North America, pp. 213, 214, and is partly modified according to the principles made 

 known by Kraatz, Rev. Tenebr. alten Welt, 69, sqq.
