A REVISION OF THE NORTH AMERICAN SPECIES OF 
Pachybrachys. By H.C. Fall (Coleoptera). 
A monographic study of the species of the genus Pachybrachys found in 
America north of Mexico, in the preparation of which paper the series of the 
genus in the leading American collections were examined. The extremely 
great variation found in the group necessitated the most careful consideration 
of the characters generally used for the separation of the species. All of the 
159 species are described, 75 of which arenew. A very carefully prepared key 
is also given.
