^ . l - 9 mm. Reddish yellow, the head a little darker, the apical 

 half of the abdomen brown. Head and nodes with a slight gloss, 

 abdomen polished and shining, thorax dull. Head microscopically 

 reticulat9-striate, thorax and nodes very finely reticulate. Abdomen 

 very sparsely pilose and punctured. Head, excluding the mandibles, 

 one-fifth longer than wide, the sides and the hind margin nearly 

 straight. The scape just reaches the posterior margin. The eyes are 

 situated just in front of the middle of the sides. The thorax is but 

 moderately constricted at the meso-epinotal suture. The profile of the 

 thorax is convex in front, horizontal above ; the dorsum of the epi- 

 notum and of the pro-mesonotum are in the same plane, and slope 

 backwards towards the declivity. The dorsum of the epinotum is 

 about half as long as the pro-mesonotum, and very little longer than 

 wide ; the declivity is sub-vertical and forms a distinct angle with 

 the dorsum. The anterior face of the 1st node is very short, and the 

 peduncle is a little shorter than the node ; the 2nd node is as wide as 

 long.

 at about the middle of the sides of the head. Median area of clvpeus 

 longitudinally striate, the carinae well defined. Mandibles quadri- 

 dentate and moderately strongly and longitudinally striate. The scape 

 extends slightly beyond the hind margin of the head. Prothorax in
