minute subapical teeth on the edge. Prothorax large and long, 
narrowed posteriorly; tegulae present; fore wings strap-like, 
reaching to the posterior face of the propodeum; propodeum 
very long, its superior angles produced into a strong acute tooth 
on each side.

$ . Head quadrate, not broader than long, occiput faintly 
emarginate. Antennae short, barely as long as the head and 
thorax together; first flagellar joint longer than the second; 
second and following barely three times as long as thick; pedicel 
twice as long as thick and more than half as long as the first 
flagellar joint; antennae inserted just above the level of the 
lower margin of the eyes. Malar space with a sharp furrow, 
shorter than the basal width of the mandible. Mandible with a 
long apical tooth and three minute subapical teeth on the edge. 
Eye separated by its own width from the hind margin of the head . 
Prothorax one-half longer than wide, obliquely narrowed pos- 
teriori}'. Wings absent, tegulae obsolete. Propodeum almost as 
long as the pronotum, much wider behind than in front, its hind 
angles slightly acute, but not toothed. 
cf. Antennae 13-jointed, longer and more slender than 
those of the female; pedicel nearly as long as the first flagellar 
joint; second and following flagellar joints subequal, each three 
times as long as thick. Ocelli obsolete as in the female. Front 
femora greatly thickened, the other legs slender, especially the 
hind ones; all tarsi long and slender, their joints all cylindrical, 
none flattened nor emarginate at tips. Abdomen armed with 
two slender, upturned spines at apex. 
The male is so similar to the female, except for the additional 
antennal joint, more slender legs and small spines at the apex of 
the abdomen that I did not recognize its sex at the time the 
species was described. It measures 2.5 mm. in length, while the 
females I have seen range from 4 to 5.2 mm. The antennae of the 
male are only slightly lighter basally while in the female the 
first three joints are honey-yellow.
