minute subapical teeth on the edge. Prothorax large and long, 

 narrowed posteriorly; tegulse 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, tegulse obsolete. Propodeum almost as 

 long as the pronotum, much wider behind than in front, its hind 

 angles slightly acute, but not toothed. 



cT. 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 witli 

 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.
