neck. The pronotum is rather flat transversely, and slopes downwards 

 and forwards ; above, it joins the mesonotum in an obtuse angle, 

 and bears a small tubercle on each side. Thorax fairly long, not 

 much constricted between the meso- and epinotum and not depressed 

 between them above. Pro-mesonotal suture obsolete, meso-epinotal 

 suture very shallow and faintly indicated. Dorsum of epinotum 

 two and a half times longer than wide, slightly concave in its apical 

 half, and at least twice as long as the declivity. Epinotal spines 

 long, thin, and acute, subparallel, oblique, one-third longer than the 

 interval between their bases. The declivity of the epinotum sub- 

 vertical, smooth, distinctly margined at the sides, the margins being 

 continued into the episternal teeth, which are short and triangular. 

 The peduncle of the 1st segment of the petiole is as long as the node ; 

 the latter seen from above, is more or less oval, slightly longer than 

 wide, fairly convex transversely, less so lengthwise ; 2nd node 

 subhemispberical, half as wide again as it is long, and one and a half 

 times wider than the 1st node ; the ventral surface bears a tubercle 

 on each side. Legs rather long, femora only moderately and gradually 

 swollen. 



Bulawayo ; not common. These specimens are decidedly larger 

 than those from East Africa, on which the species was founded 

 (3-8-4 mm.), but there is no other difference. (S.A.M., E.M., Gr.A.

y . 4' 3 mm. Very dark brown ; abdomen and femora, except the 

 bases of the latter, black ; tibiae, tarsi, antennae and mandibles 

 brownish or reddish-yellow. A few yellowish, stiff hairs on the 

 clypeus and abdomen. Legs and antennae with a very short and 

 scanty pubescence. Head fairly sti*ongly striato-rugose. Thorax 

 longitudinally rugose, more coarsely so on the dorsum than on the 

 sides, also somewhat reticulate ; dorsum of epinotum strongly and 

 transversely rugose, the declivity transversely rugulose. Nodes very 

 strongly reticulate-rugose. Head and thorax subopaque, the spaces 

 between the rugae shining. Abdomen smooth and shining, except 

 the extreme base, which is somewhat dull and finely striate. 



Head rectangular, excluding the mandibles very little longer than 

 wide, the sides and posterior margin almost straight, the posterior 

 angles rounded. Clypeus with a strong median carina, convex 

 transversely and lengthwise, the anterior margin straight. The
