occipital border. Carinae of cheeks strong, tridentate, the two anterior teeth 

 blunt, the basal one smaller and more acute. Mandibles finely denticulate. 

 Frontal carinae approximated, elevated, broadly rounded. Antennae thick, 

 their scapes extending to a point opposite the posterior border of eyes; funicu- 

 lar joints 2-10 transverse; terminal joint as long as the six joints preceding. 

 Eyes rather large and convex, situated at sides of head a little in front of middle. 

 Thorax narrower than the head, more than twice as long as broad, slightly 

 narrowed in the mesonotal region, as broad in front as behind, without sutures; 

 in profile moderately convex above, rounding into the declivity which is flat 

 and submarginate laterally. Petiole a little narrower than epinotum, from 

 above distinctly broader than long, slightly broader in front than behind, 

 rounded at sides posteriorly, and truncate in front; in profile a little longer 

 than high, with a stout tooth anteroventrally. Postpetiole broader than 

 petiole, and broader than long, slightly narrowed in front, sides feebly convex. 

 First gastric segment a little longer than broad and as broad in front as behind. 

 Pygidium with a circular, impressed disc at middle, its border spinulose. Legs 

 rather long and slender. 



Shining. Mandibles with scattered punctures. Head and thorax with 

 piligerous punctures, which are fine and scattered on front of head, coarser and

 coarse, and abundant but not confluent. Gaster with finer, regular punctures.
