Obisium brunneum Hagen. — Record Am. Ent , 1868. 



This is the common species in the northern states. It occurs 

 under leaves in woods. Ithaca, N. Y.; Sea Cliff, L. I.; Salineville, 

 Ohio, (A. D. MacClillivray); Poughkeepsie, N. Y., (G. Van Ingen); 

 Cambridge, Mass., (Hubbard); Detroit, Mich., (Hubbard); and 

 one specimen from Wasatch ami Alta, Utah, (Hubbard), seems to 

 be the same species.

One adult and several young, without locality (Hubbard 1. 

 This was in the same vial as C//<"Arw/'jr deiitatiis^ which I think must 

 be from Florida.
