A NEW GENUS OR SUBGENUS OF PACHYNEURINE 
CHALCID-FLIES. 
By A. A. GtRavtt, 
Bureau of Entomology, Washington, D. C. 
Propachyneuronia gen. nov. 
Based on Enecyrtus siphonophore (Ashmead) of which Pachy- 
neuron micans Howard, P. aphidivorum Ashmead and Pachy- 
neuron maidiaphidis Ashmead are synonyms (types examined). 
The same as Pachyneuron but the antenne bear three ring-joints. 
The genotype has the clypeus radiate striate but not strongly, 
acutely produced (a smaller tooth on each side of the clypeus); 
the propodeum bears a neck and is plane (except for a few foveze 
along the cephalic margin) with the spiracle small, its own diam- 
eter from the cephalic margin. Mandibles acutely 4-dentate. 
Scape metallic, the funicle joints all short. Abdominal petiole 
transverse, with a tooth from each side. Segment 2 of the abdo- 
men entire as to its caudal margin, occupying about a third of the 
surface. Stigmal vein longer than the marginal.
