152 INSKCUTOR INSCITITB MENSTRUUS 



Encyrtocephalus simplicipes Ashmead. Genotype. 



Pseudorileya Girault is a synonym. The genotype (simpli- 

 cipes) differs from albiclava in having the cephalic margin of 

 the propodeum broadly black between the spiracles, the f unicle 

 is black or nearly, there is only a round hyaline dot in the large 

 infuscation against the stigmal vein, the abdomen dorsad is 

 depressed, the caudal margains of the segments straight, seg- 

 ment 2 largest, occupying nearly a third of the surface. 

 Scutellum distad less punctate only, the sculpture not sharply 

 Remarked. From the type in the U. S. National Museum, a 

 female.
