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 are new. A very carefully prepared key 

 is also given.
