Most of the species described in this paper are of economic impor- 

 tance, and for reference in economic literature their early description 

 is desirable. The series from the species of Agromyza is noteworthy 

 in view of the number of species previously described as parasites of 

 the species of that genus. In this paper, in all cases where both sexes 

 of a species are described, that last described is the allotype. 



Superfamily VESPOIDEA. 



POLISTES RUBIGINOSUS Lepelletier 



Polistes perplexus Cresson. 

 Polistes generosus Cresson. 



A large nest of this species containing many males was collected at 

 Rosser, Texas, September 25, 1905, by Messrs. F. C. Bishoff and 

 C. R. Jones. In addition to many normally colored males there were 

 also several of each of the color variations described by Mr. Cresson 

 under the two names listed above as synonyms. This nest made 

 it possible to establish the synonomy and confirm the suspicion 

 voiced by Mr. Cresson in his original descriptions of the two color 

 variatjans of the male. 



Superfamily CYNIPOIDEA. 



AGLAOTOMA TEXANA, new species.

 along edge and a large fovea at apex; propodeum rugose; wings hya-
