Mesonotum longer than wide behind, widest in front, feebly convex 

 transversely, straight longitudinally ; meso-metanotal impression 

 feeble. Stigmatic tubercles of metanotum prominent, subcorneal in 

 profile. Meta -epinotal suture fairly deep. Dorsum of epiuotum 

 convex lengthwise, a little wider than long, not much narrowed at the 

 base, seen from above broadly campaniform, armed with two fairly 

 long oblique and feebly divergent teeth, longer than their basal width; 

 declivity as long as the dorsum, steeply inclined, the stigmata at the 

 base not very prominent. Petiole two and a-half times longer than its 

 node is high, the latter with a fairly large dorsal face, which is as long 

 as wide and bears posteriorly two long, subvertical and thin spines. 

 The spines are longer than the node is wide and at least three times 

 longer than their basal width. Abdomen very convex transversely, 

 longer than wide, pointed towards the apex. 



9 . 5 - 7 mm. Black, legs brownish, tarsi ochreous, mandibles 

 ferruginous, antennae brown, the basal half of the scape more or less 

 ochreous. Anterior third of the head with a fine, decumbent and 

 whitish pubescence. Abdomen, legs and antennae densely pubescent, 

 the pubescence closely adjacent on the abdomen and of a golden 

 ochreous colour, somewhat pi'uinose ; the apical margins with a few 

 erect, short and blunt hairs. Whole body, including the legs and 

 antennae, dull. Head and thorax very regularly coriaceous, the 

 abdomen rugulose. Mandibles slightly shining, finely striate, sparsely 

 and coarsely punctured. The shape of the head and thorax resembles 

 that of spinosior $ . The petiole without a long peduncle behind the 

 scale, seen from the side cuneiform, higher than long, the upper edge 

 convex transversely, unarmed. Deiilated. 



Hillside, Bulawayo. A very distinct and handsome species, easily 

 recognised by the exceptionally long petiole in the £ , and the 

 pruinose-golden sheen on the abdomen of the 9 . (S.A.M., P.M., 

 Gr.A. colls. ; types in my collection.)
