54 Annals of the South African Museum. 



brown, mandibles ferruginous. Legs, antennae, and body covered 

 with a pale yellowish and rather long pubescence ; mandibles, 

 clypeus, and apical margins of abdominal segments with long pale, 

 semi-erect hairs. Head dull, very finely and closely punctured. 

 Thorax slightly shining, evenly but less closely punctured than the 

 head. Abdomen shining, 1st segment finely and distinctly, 2nd 

 segment faintly punctured. 



Head, excluding the mandibles, a little longer than wide, sides 

 convex, occipital margin straight, posterior angles rounded but 

 distinct. The angulation of the surface of the head, between the 

 dorsal and genal regions, characteristic of the genus, is so feeble in 

 this species as to be hardly noticeable. 



Clypeus shining and very short, anterior margin moderately 

 convex, raised in the middle to form a shining carina which is fused 

 with the frontal carinae. Mandibles triangular, shining, sparsely 

 punctured, furnished with about 7-8 teeth. Scape reaching back as 

 far as the occipital margin, flattened and incrassate towards the 

 apex ; flagellum strongly incrassate towards the apex, the last 

 4 joints forming a club ; 1st joint longer than wide, 2nd-10th joints 

 wider than long. Eyes consisting of about 6 ill-defined facets, very 

 small and flat, situated in the anterior fifth of the sides of the head. 

 Frontal carinae wide, their external margins very convex. Pronotum 

 not quite so wide as the head, wider than long, rather flat above and 

 at the sides, rounded in front and with the anterior angles rounded 

 but fairly distinct. Pro-mesonotal suture strong, meso-epinotal suture 

 feeble. Mesonotum ovoid, wider than long, hardly two-thirds as 

 long as the pronotum. Dorsum of epinotum very narrow, widening 

 towards the apex ; declivity rather abrupt and nearly vertical, smooth 

 and shining. The upper surface of the node, seen from above, is in 

 the shape of a wide-based triangle, the apex very rounded ; seen from 

 the side, the node is convex above from side to side, the anterior face 

 slopes backwards and is concave from below to above, the posterior 

 face vertical and concave from side to side. Ventral lamella of 

 petiole produced and widely truncate at the apex. Abdomen 

 elliptical, 1st segment with the anterior face sloping forwards, wider 

 at the apex than at the base, as wide as long ; 2nd segment a little 

 longer than the 1st, the constriction between the two segments 

 moderate. Anterior femora and tibiae stout. 



$ (hitherto undescribed). 4 - 2 mm. Black, scape and 1st joint 

 of flagellum, trochanters, apices of femora and tibiae, extreme bases 

 of tibiae and all the tarsi pale brownish yellow. Head and thorax 

 very shallowly punctured, abdomen impunctate. Whole body
