Surface of body and appendages smooth and shining, witli very 
sparse and indistinct, piligerous punctures. Mesopleurte 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, witli well- 
developed, toothed mandibles. Antennse 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 tootli at the anteroventral end of the 
petiole. Postpetiole short, higher than long, convex above. Gaster 
large, elliptical. Middle and hind tibise 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 coverei 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. Antennse 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,
