Mandibles smooth; head densely punctate and covered with large, 
shallow fovese which make it appear coarsely reticulate-rugose. Thorax 
with similar but larger and deeper fovese in front, bnt with most of 
the dorsum and pleurae traversed by very coarse, wavy, longitudinal 
rugse, which converge somewhat behind and terminate in the ridge 
bordering the smooth epinotal declivity. Neck with similar rugse which 
terminate behind in the pronotal ridge. Petiole and postpetiole covered 
with fovese like those on the head, but larger, deeper and more conspi- 
cuous; on the dorsum of the petiole they have a somewhat concentric 
arrangement, on the sides they are replaced by longitudinal ridges like 
those on the pleurse. Anterior vertical surface of the petiole smooth. 
First gastric segment densely punctate and with scattered foveolse over 
its entire surface. Remaining segments apparently with a similar 
sculpture. 
Hairs delicate, moderately abundant, short and erect on the body, 
scapes and legs. First and terminal gastric segments finely and rather 
densely pubescent. 
Male (Fig. 2c). Color black. Length 9 mm. 
Body slender. Antennse rather long; scape cylindrical, slightly 
incrasated, hardly longer than joints 2 — 11 of the funiculus, which 
are subequal and somewhat shorter than the terminal joint; first 
funicular joint very short, broader than long. Mandibles well-developed, 
with straight, indistinctly denticulate masticatory borders. Clypeus 
with broadly rounded anterior border and very prominent median 
carina. Frontal carinse long, straight, slightly diverging behind. Eyes 
and ocelli moderately large. Posterior Corners of head prominent, 
posterior border with a raised margin. Thorax with distinct Mayrian 
grooves, propleurse concave, mesopleurse large and convex. Epinotum 
sloping and convex in front, its posterior surface concave and separated 
from the base by a prominent ridge which is distinctly notched in the 
median dorsal line. Petiole in profile as long as high, with straight, 
sloping anterior and slightly rounded dorso-posterior surface ; its ventral 
surface with a large blunt, anteromedian tooth. Postpetiole campanu- 
late, longer than the petiole, slightly longer than broad. Wings folded 
and in such a position that their venation cannot be described. Legs 
slender. Head, thorax and petiole very coarsely reticulate-rugose. 
Propleurse longitudinally rugose. Postpetiole and gaster smooth, with 
concave, scattered, piligerous punctures. 
Hairs short, erect and moderately abundant on the body, sparser 
on the legs.
