about as long as the thorax, the sides feebly convex. 1st and 

 2nd segments distinctly longer than wide, 2nd segment longer 

 than the 1st. Legs rather short, anterior femora thick and broad, 

 posterior coxae not toothed. 



cT . 6-5 mm. Eust-red, antennae and tarsi yellowish red, eyes 

 black. Puncturation and pubescence as in the £ , but the punc- 

 turation is a little finer, and the pubescence shorter and less 

 dense. 



Head, excluding mandibles, as long as it is wide across the eyes. 

 The latter very large, the internal margins sinuate, occupying more 

 than three-quarters of the sides of the head. Mandibles large and 

 shaped as in the £ . Clypeus similar to that of the $ , but the 

 posterior margin is more distinctly defined. The frontal area is 

 an elongate triangle, indistinctly defined but continued into the 

 median depression of the vertex, which ends at the anterior ocellus. 

 The ocelli not very large and not situated on a raised area. The 

 frontal carinae are widely divergent behind. Antennae filiform, 

 extending back as far as the 1st abdominal segment ; scape short, 

 not longer than the distance separating the two posterior ocelli ; 

 1st joint of flagellum less than half as long as the scape, 2nd joint 

 as long as the third. Pronotum rounded in front and at the sides, 

 at least three times as wide as long. Mesonotum rather flat 

 posteriorly, moderately convex in front and at the sides, not rising 

 very much above the level of the pronotum. Mayrian furrows and 

 parapsidal sutures very distinct. Scutellum a little wider than 

 long, not gibbous. Dorsum of the epinotum much wider at the 

 base than at the apex, where it forms a distinct angle with the 

 declivity. The latter is distinctly margined all round, nearly 

 quadrangular, not vertical as in the £ , but sloping very obliquely. 

 The node of the petiole is similar to that of the $ , but is 

 not so high, nor truncated behind, the dorsal profile forming a 

 continuous curve rising from front to back. The abdomen as in 

 the $ ; the pygidium ends in a short curved spine. Legs longer 

 and thinner than in the £ . Wings smoky, nervures pale brown, 

 stigma black. 



Types £ and $ in the Durban Museum. 



Stella Bush, Durban. (C. B. Cooper.) 



This species differs from the allied forms, frontalis, modesta, tenuis, 

 Emery, etc., by the entire absence of teeth on the posterior dorsal 

 margin of the node, and by the widely separated frontal carinae.
