"$, 7-7 mm. Like the $. The apical margins of the dorsum of the 

 very wide epinotum is undulate, convex in the middle, concave on 

 each side, and ending in obtuse teeth. Pronotum with two strong 

 short spines, produced in front and outwards, lamelliform. Wings 

 faintly tinged with brown, with brown stigma and nervures. Other-

"$, 7 mm. Black, slightly shining, ends of the mandibles, the 

 antennae and, to some extent, the legs brown-red. Pilosity wanting ; 

 the decumbent pubescence very fine and short, sparse on the head 

 and thorax, more plentiful on the abdomen, tibiae and tarsi. Man- 

 dibles very finely rugulose, sparsely and coarsely punctate. Clypeus 

 very finely coriaceous, sparsely punctured, fairly shining. The frons 

 finely and longitudinally rugulose, the vertex punctate and rugulose. 

 Thorax finely punctured, partly rugulose, with 4 teeth, the pronotum 

 having on each side a triangular and acute tooth, directed outwards 

 and somewhat forwards (lamelliform or like a ledge) ; the epinotum 

 with a short and acute tooth on each side. The petiole with a thick, 

 wide and rounded scale, the arcuate upper margin of which is armed 

 with 4 equidistant teeth, of equal size, short, straight, directed 

 upwards and somewhat backwards. The abdomen fairly super- 

 ficially shagreened and reticulate."

 petiole are twice as far apart as they are from the outer spines. The
