? 7-7*5 mm. Black, mandibles, clypeus, antennae, legs and 

 apex of the abdomen more or less ferruginous. Pubescence pruinose 

 and rather thin, pilosity absent except on the last segment of 

 the abdomen. Microscopically rugulose, sparsely and shallowly 

 punctured on the head, meso- and epinotum, petiole and first two 

 segments of the abdomen. The pronotum and apical segments of 

 the abdomen with very sparse and minute punctures ; the punctures 

 on the sides of the head and on the epinotum are larger and deeper 

 than on the rest of the body. Head sub-quadrate, as long as 

 wide, sides feebly convex, posterior margin almost straight, posterior 

 angles rounded. The anterior margin of the clypeus feebly arcuate, 

 posterior margin indistinct. Mandibles dull, finely punctuate- 

 striate, triangular, external margin convex or very slightly sinuate, 

 masticatory margin finely denticulate. Frontal carinae broad, nar- 

 rower and slightly convergent behind. Eyes large, their posterior 

 margins lying in front of the middle of the sides of the head. Scape 

 of the antenna reaches back a little beyond the occipital margin ; 

 lst-5th joints very little longer than wide, 6th-10th joints about as 

 long as wide, apical joint half as long again as wide. The pronotum 

 is a little wider than the rest of the thorax, and narrower behind, 

 the sides of the rest of the thorax nearly parallel. Pro-mesonotal 

 suture distinct. The declivity of the epinotum is very steep but not 

 vertical, concave and distinctly margined, the margin above ending 

 on each side in a broad, rounded and stumpy tooth. Node of 

 petiole half as long again as wide, a little longer than high, convex 

 from side to side, a trifle wider behind than in front, anterior face 

 nearly vertical but considerably rounded above, posterior face 

 vertical and produced dorsally into three obtuse teeth, the median 

 tooth being wider and longer than the lateral teeth. Ventral lamella 

 very slightly produced. Abdomen oblong, 1st segment very little 

 longer than wide, 2nd segment longer than the 1st, and one-fifth 

 longer than wide. Legs rather short, posterior coxae armed on the 

 inner margin with a blunt tooth. . 



Matopo Hills, S. Rhodesia. Type in my collection. 



This variety appears to differ from the type form of Madagascar 

 only by the longer node of the petiole.
