Genus ATOPOSOMOIDEA, new genus. 



Female. — Apparently this genus comes near Atoposoma Masi, as 

 the proposed name suggests, and is distinguished chiefly by the solid 

 thorax, naked eyes, somewhat less elevated vertex, slightly different 

 dentation of the mandibles, low insertion of the antennse, different 

 proportions of the antennal sclerites, and greater length of post- 

 marginal vein — all of which are indicated in the accompanying illus- 

 tration (fig. 7). Atoposoma is closely related to Zagrammosoma 

 Ashmead, also parasitic on a Lepidopterous larva.
