apex. Sides of head moderately convex, posterior angles rounded. 

 Pronotum wider than long, the dorsal region distinctly, and rather 

 angularly delimited from the sides. Mesonotum ovoid, narrower at 

 the base. Pro-mesonotal suture well defined, meso-epinotal suture a 

 little less distinct. Dorsum of epinotum narrow, very little longer 

 than the mesonotum ; declivity tiiangular, with a faint median longi- 

 tudinal impression. Node of petiole rounded above, convex from 

 side to side in front, and flat behind. Seen in profile, vertically 

 truncate in front, steeply sloping behind, and with sharply defined 

 lateral margin separating the anterior and posterior faces. Ventral 

 lamella triangularly produced along its whole length. The basal face 

 ■of the 1st abdominal segment is vertically truncate, forming a dis- 

 tinct, though obtuse, angle with the dorsal surface. Below, at its 

 junction with the petiole, the segment is produced into a strong 

 tooth. Second abdominal segment slightly wider and longer than the 

 1st, the constriction between the two segments feeble. Seen from in 

 front or behind the node of the petiole is wider above than below, 

 and of an ovoid shape. Legs comparatively long. Claws with a 

 small tooth near the base.

$ . 11-12 mm. Black, mandibles more or less castaneous red, legs 

 and antennae brownish black. The whole body sub-opaque, the pos- 

 terior face of the node of the petiole shining, finely pubescent, 

 •closely and very finely punctured all over, except the posterior face 

 of the node which is less densely punctured, and the declivity of the 

 ■epinotum which is reticulate-punctate or very finely rugulose. A 

 few long hairs on the mandibles and apex of the abdomen. Head 

 very little longer than wide, with the posterior angles considerably 

 rounded, the sides moderately convex. Clypeus very convex in the 

 middle, hardly carinate. Frontal area lanceolate, the depression or 

 sulcus behind it moderately long. Eyes within the anterior half 

 of the head, and separated from the base of the mandibles by a 

 distance a little longer than their own long diameter. Mandibles 

 shining, finely striate near the base, sparsely and coarsely punctured 

 near the apex, with 13-15 irregular teeth, and a deep oblique fovea
