Var. shinshendensis, Forel. 

 Eev. Zool. Afric, vol. 2, p. 327, £, 1913. 



" £ . 4-4 - 2 nam. A little larger than the type of the species. 

 Black, legs and mandibles brown. The sculpture is coarser than in the 

 type, even on the abdomen. Otherwise identical. 



" Shinshenda, Katanga (Dr. Bequaert)." 



I have some specimens from Bembesi, S. Ehodesia, which appear to 

 agree with this variety. The superimposed rugae on the head are 

 stronger and more abundant. The thorax is also coarsely and 

 irregularly rugose. The epinotal spines are as long as, or a little 

 longer than the dorsum of the epinotum. 



1/ . 8 mm. (hitherto undescribed). The sculpture is like that of 

 the type of the species, but stronger everywhere. The head is more 

 convex above transversely, the occipital sulcus is less deep, and the 

 occipital emargination shallower, hardly more than half as deep as in 

 the type-species. The epinotal spines are a little longer, stouter and 

 somewhat compressed (blade- shaped). Otherwise like the type of the 

 species. 



Bembesi, S. Rhodesia. Forming populous nests in sandy soil. A 

 very pugnacious insect. (S.A.M., E.M., Gr.A. colls. ; type of 1/ in my 

 collection.) 



Var. malindana, Forel. 



Ann. Soc. Ent. Belg., vol. 57, p. 135, £ , 1913. 



£ . 4*5-5 - 2 mm. Black, mandibles, scapes and legs dark-brown, 

 tarsi and flagellum ferruginous. Sculpture like that of shinshendensis, 

 but the posterior half of the head is widely reticulate-rugose. The 

 base of the abdomen finely areolate and aciculate, but more strongly 

 so than in the type of the species. Posterior margin of the head 

 shallowly concave. Posterior lateral angles of pronotum strong, sub- 

 dentiform. Epinotal spines very long and acute, longer than the 

 dorsum of the epinotum. Second node of petiole with a conical 

 projection on each side, a little less obtuse than in shinshendensis. 

 Malindi, S. Ehodesia. (E.M., O.A. colls.) 



Eace micraetifex, Forel. 

 Deutsch. Ent. Zeitschr. Beiheft, p. 215,1/, £ , 1913. 



1/. 6 - 5-7 - 2 mm. Colour similar to that of the type-species, but 

 darker. Sculpture also similar, but stronger, especially on the head, 

 where the transverse rugae on the posterior part are coarser and wider
