Surface of body and appendages smooth and shining, with very 

 sparse and indistinct, piligerous punctures. Mesopleur* and epinotum 

 densely and coarsely, sides of petiole more finely punctate; this sculp- 

 ture closely resembling that of E. longi. 



Hairs slender and sparse, suberect on the body, shorter and more 

 reclinate on the legs and antennal scapes. 



Color reddish brown throughout. 



Female (Fig. 16c). Length about 5,5 — 6,5 mm. 



Head nearly as broad as long, subrectangular, convex, with well- 

 developed, toothed mandibles. Antennae small, similar to those of the 

 worker. Eyes and ocelli moderately large. Thorax robust, somewhat 

 longer than high, with short, stout, recurved epinotal spines. Petiole 

 in profile with a rather acute node, which has both its anterior and 

 posterior declivities concave and of about the same length. There is 

 a stout, laterally compressed tooth at the anteroventral end of the 

 petiole. Postpetiole short, higher than long, convex above. Gaster 

 large, elliptical. Middle and hind tibiae with well -developed spurs. 

 "Wings large, with single cubital, radial and discal cell. The radial 

 cell is elongate and closed as the anterior branch of the cubital vein 

 unites with the costa. The discal cell is large and trapezoidal owing 

 to the recurrent vein not being parallel with the basal. The second 

 branch of the cubital vein comes off a little beyond the middle of 

 the cubital cell. Apterostigma well-developed. 



Mandibles with scattered punctures. Sculpture of head, thorax, 

 petiole and postpetiole apparently very much as in the female of E. longi. 



Hairs slender, erect and abundant on the body, sparser and more 

 reclinate on the appendages. Wings covered with minute hairs. 



Body black; legs brownish; wings brown with darker veins and 

 stigma. 



Male (Fig. 16d). Length about 5 mm. 



Head apparently as broad as long, with rounded posterior corners 

 and very large and prominent eyes and ocelli, the eyes . situated far 

 forward, so that the cheeks are extremely short. Mandibles small but 

 overlapping and dentate, with acute tips. Clypeus with its anterior 

 border angularly projecting in the middle. Antennae slender, 13-jointed, 

 about as long as the head, thorax and pedicel; scape slightly thicker 

 than the funiculus, about twice as long as broad; first funicular joint 

 not enlarged or globose, somewhat longer than broad, second joint 

 longer than the scape and any of the succeeding joints, which are 

 subequal and cylindrical. Thorax with prominent, rounded mesonotum,
