mens of Platynella were studied at the United States National Mu- 
seum. Dr. George E. Ball, Department of Entomology, University of 
Alberta, Edmonton, Alberta, Canada, lent me eight specimens from 
his extensive collection of Mexican carabids and made valuable com- 
ments on an early draft of this paper. Senor Jorge Hendrichs S., 
Mexico City, clarified the locations of the older collecting sites. 
It is now evident that Bolivaridius is a junior synonym of Platy- 
nella, and that B. ovatellus is a synonym of Anchomenus (Platynella)
