few pilose punctures, striato-punctate in front and pubescent. The 

 abdomen is polished and sparsely punctured. The anterior wings are 

 slightly greyish yellow, nervures and stigma brownish yellow. Head 

 with the closed mandibles triangular and rounded, narrower than the 

 thorax across the tegulae ; without the mandibles, a little wider than 

 long. Clypeus triangular, strongly convex transversely, without 

 carinae, the anterior margin feebly sinuate on each side, so that the 

 median portion projects in an obtuse angle ; the posterior portion of 

 the clypeus between the frontal carinae separated off from the front 

 portion by a transverse impression. A small frontal area present, 

 with a frontal sulcus extending from it to the anterior ocellus. . . . 

 The scape extends back as far as the posterior ocelli ; the flagebum 

 with a distinct 3-jointed club, the 1st joint of the flagellum two and 

 three-quarter times longer than wide, the 4 following joints as long as 

 wide, the 6th a trifle longer than wide, the 1st and 2nd joints of the 

 club distinctly longer than wide, the last joint almost as long as the 

 three preceding taken together. The fairly large and convex eyes lie 

 in front of the middle of the head. The posterior margin of the head 

 straight. The thorax is widest in the middle ; the pronotum vertical, 

 the mesonotum in front and at the sides strongly convex, in the middle 

 feebly so ; the dorsum of the epinotum sloping, the declivity vertical 

 and with a rounded brow. The 1st joint of the petiole has a little 

 tooth below, the 2nd is even more campaniform than in the £ , it is 

 about twice as wide as long and twice as wide as the 1st node, rounded 

 at the sides, widest just in front of the hind margin. The abdomen is 

 a little more than twice as wide as the 2nd node, and not quite twice 

 as long as it is wide."

 thick two-jointed club. Mandibles thick, edentate or with two or 

 three blunt teeth. Head quadrate. Clypeus with the median area 

 raised and produced rather far back between the frontal carinae, 

 channelled down the middle, the sides of the channel forming a carina 

 on each side, which converge behind, and in front end in two acute 

 teeth projecting beyond the margin of the clypeus. Frontal carinae
