170 AMERICAN HYMENOPTERA. 



Opliion undulatus Grav. 

 Taschenberg* records this species, now placed in the 

 Genus Allocamptus, from Brazil, and North America, taken 

 from Sahcrnia {Samia) cecropia. It is a well-known Old 

 World species, and as no other record of its capture in 

 America exists, the determination was probably erroneous.
