medially; ocell-ocular and postocellar lines and diameter of lateral 

 ocellus in female subequal, ocelli in male a trifle larger; thorax 

 sparsely punctate, more densely so on mesoscutum, least densely 

 so on side of propodeum, latter polished medially, apical carina weak 

 and curved backward medially; radius in middle of stigma; petiole 

 of areolet about equal to rest of intercubitus ; nervellus postfurcal; 

 hind coxae black and white; black color of thorax more extensive 

 than in following species, covering about as much area as yellow; 

 lateral black mark of propodeum reaching nearly to apex and embrac- 

 ing the spiracle. 



EIPHOSOMA (EIPHOSOMA) BnUESI, new species. 



Allied to texanurn Cresson and runs to that species in Brues' key * 

 to the species of the genus ; but differs principally as follows from spec- 

 imens of that species in the United States National Museum : 



Female. — Length, 10 mm.; antennae, 4.5 mm.; ovipositor, 2.5 mm. 



Malar space distinctly shorter than basal width of mandible; face 

 only slightly narrower than frons; ocelli larger, being nearly twice 

 as long as ocell-ocular line; thorax and propodeum rather densely 

 punctate; yellow color of thorax more extensive than black, lateral 

 mark of propodeum small, not extending nearly to apex and confined 

 to depression between propodeum and metapleurum, interrupted 

 or constricted at spiracle. 



Agrees with above description of texanurn otherwise. 



Type locality. — Granger, Texas. 



Tijjie.— Cat. No. 22859, U.S.N.M. 



Described from two females, the type taken May 20, 1895, and 

 determined by Ashmead as texanurn,. The paratype is labeled merely 

 ^'Hunter No. 2505 P. X." 



The paratype differs from the type but very little, the lateral 

 mark on the propodeum being slightly larger, and the areolet of the 

 right wing being entirely lacking while that of the left wing is very 

 small and poorly defined. 



Named in honor of Dr. C. T. Brues, of the Bussey Institution, 

 Cambridge, Massachusetts. 



Genus PRISTOMERUS Curtis. 



In all published arrangements of the tribes of the Ophioninae the 

 tribe Pristomerini has been placed next to the Cremastini and sepa- 

 rated from that tribe only by the character of the toothed hind 

 femora. Schmiedeknecht - mentions several other characters, prin- 

 cipally of venation, in his description of the tribe, all of which are 

 to be found in one or another of the genera that he places in the 

 Cremastini. In his tribal key he modified the femoral character to
