OISTELIDAE LAGRIIDAE MONOMMIDAE ANTHICIDAE. 



i Cistela erythropa Kirby, Fauna Bor. Am. 239, cannot be identified from the description, but I 

 suspect, if the tarsi are not lobed, that it is one of the species of Androchirus. 



a The sequence of the following families is different from that adopted in the Classification of 

 Coleoptera of North America, in which my effort was to arrange them in such manner as to exhibit 

 the gradual degradation of type from Tenebrionidae to Stylopidse. The arrangement in tho present 

 List is copied frum DuVal's Genera des Colopt. d'Europe, and exhibits the collateral relations of the 

 families in a more perfect manner than any other known to me.
