 third, spiracles, small oval; legs slender, femoral tooth at apica 

 third, very small, denticles obsolete, calcarium of hind tibia reaching

Type locality. — Pyziton, Claj^ County, Alabama. 



Other localities. — Coleta, Alabama, and College Station, Texas. 



Type.— Ca.t. No. 22860, U.S.N.AI. 



Described from three females, the two Alabama specimens col- 

 lected by the late H. H. Smith, for whom tJie species is named, and 

 the Texas specimen by Natlian Banks. 



Paratype a has the body and the hind femora and coxse more 

 rufous and the femora slightly infuscate inside. 



PRISTOMERUS (AREOLOPRISTOMEKUS) DLBIA (Brues). 



Pristomeridia {?) dubia Brues, Psyche, vol. 18, 1911, p. 24, female, pi. 6, figs. 

 9 and 10. 



This species, which Brues doubtfully placed in Pristomeridia, is 

 evidently very closely related to smltJii Cusiiman. A comparison of 

 Brues' s description with smithi shows the following differences : First, 

 two joints of flagellum equal in length; propodeum excavated behind, 

 basal area quadrangular; spiracles round; second tergite as long as 

 first, shining on basal third; wings slightly infuscated apically; 

 posterior femora largely piceous. 



The unique type is from Blue Hills, near Boston, Massachusetts.
