Subfamily CERCERINAE 



This subfamily contains only two genera, Cerceris and Eucerceris. The former contains nu- 

 merous species and occurs in all major zoogeographic regions. The latter genus has comparative- 

 ly few species, occurs in the New World only as far south as Panama, and the majority of species 

 are Nearctic So far as known the New World species prey upon Coleoptera only as do most of 

 the Old World species, but a few of the latter are known to prey upon bees, wasps and chalci- 

 doids.
