TENEBKIONIDAE. 



1 Although the middle trochantin is scarcely visible in this species I do not think it can be properly 

 separated from the genus Tenebrio. 



2 The synonymy of the two species of Alphitobius, hoth of which are introduced, is copied from 

 the excellent work of Mulsant, Coleopt. France, Latigenes, p. 236, 238. 



3 This gonus was characterized by me under the name Phellidius in the first issue of the Class. 

 Col. N. America, p. 236, but on learning that it had been previously described by Caude'ze, the 

 proper alteration was made in the next issue.
