The native species belonging to these genera have been enumerated by me in the 

 Proci 1 dings of the Academy of Natural Sciences above mentioned. For the purpose of 

 making the present paper complete, I will here add, to what is there contained, diagno 

 of Say's specie-, which are there only mentioned by name. It is ne< 1 ssarj first to state, 

 that I have muted the genus Isarthrus Lee. with Fornax, as l>eiiiL r not sufficiently distinct. 

 The genus Onychodon Newman^ of which I have procured the typical Bpecies, must 

 he muted with Fornax: from the very loose manner in which Newman's descriptions 

 were drawn up, the affinity of Onychodon to the Eucnemides has not been recogni ed; 

 nor is there any thing in his description (except the lateral grooves for the reception of 

 the antennae) which indi I to hi; other than a true Elateride.
