the 1st abdominal segment, except the base, brownish-yellow. Mode- 

 rately shining, including the legs. Pilosity scanty, composed of very 

 thin, short, and pointed hairs, pale yellowish. Head sparsely and 

 longitudinally striato-rugose, more reticulate at the sides. Thorax 

 reticulate-rugose, the floor of the meshes finely and shallowly rugulose, 

 the sides of the thorax more closely but less sharply reticulate. Nodes 

 with a few feeble rugae. Abdomen moderately shining, very clearly 

 and evenly punctate, the punctures small. 



Head, excluding the mandibles, one-sixth longer than wide, the sides 

 parallel, the hind margin shallowly concave, the posterior angles 

 narrowly rounded. Eyes very convex, prominent, and large, placed in 

 the middle of the sides. Frontal carinae prolonged back as far as the 

 posterior sixth of the head, moderately divergent. Faint traces of 

 demiscrobes present. Clypeus with a few longitudinal striae, hardly 

 carinate. Mandibles smooth and shining, very finely and sparsely 

 punctured, the masticatory margin long, armed with three distinct and 

 small teeth in front and four smaller ones behind, the teeth widely 

 separated. Thorax elongate, quite twice as long as wide in front, the 

 dorsum feebly marginate at the sides and in front, very slightly con- 

 stricted between the meso- and epinotum. The epinotal teeth are very 

 minute, much shorter and smaller than the episternal, which are acute 

 and triangular. The peduncle of the 1st segment of the petiole is 

 almost as long as the node, and bears a small and sharp tooth below 

 near the base ; the node is a little longer than wide, and seen from the 

 side, very convex from front to back. The 2nd node is one-third 

 wider than the 1st, and one-third wider than long, transversely oval, 

 narrower and lower in front than behind. Femora swollen in the 

 middle.

" ^. 2 - 2-2 - 5mm. Like simillimum i. sp., but the frontal carinae 

 are straight or only feebly divergent (not curving round again towards 

 each other posteriorly). Eyes nearer to the anterior than to the 

 posterior angles of the head. Thorax rather longer and narrower. 

 Epinotum with two elongate tubercles, barely dentiform. First node 

 of petiole less thick, abruptly truncate and highest in front, sloping 

 convexly backwards from the anterior margin. Both nodes shining, 

 with a very shallow sculpture ; abdomen smooth. The club is shorter 

 than the rest of the flagellum (quite as long as the rest in simillimum
