" $ . T9 mm. Apart from its smaller size, this form differs from 

 the type of the species by its sculpture, which is much more feeble 

 everywhere, by the more obtuse lobes or denticulations of the margin 

 of the thorax, by the thinner and more squamiform nodes, and by the 

 shorter thorax, which is one and three-quarter times wider than long. 

 The head is narrower than the thorax (equally wide in the type 

 species). Epinotal spines entirely absent, the epinotum being abso- 

 lutely unarmed. The woolly and abundant pilosity is a little shorter. 

 Mto-ya-kifaru, East Africa." 



Specimens taken near the Victoria Falls have been named for me 

 by Dr. Santschi as being of this race. Excepting their greater size, 

 they agree well with the above description, but not more so than they 

 do with Emery's description of inermis and with his figure of the 

 same. Emery does not mention the pro-mesonotal suture, which is 

 well defined in these specimens, and ends at each side in a deep pit, 

 which appears to have been formed by the fusion of the opposed outer 

 angles of a former excision.

^ . 2 - 7-2 - 9 mm. Head, thorax, and nodes yellowish-brown, 

 abdomen dark brown, legs, antennae, and mandibles ochreous -yellow. 

 Pilosity pale yellowish, fairly long and abundant. On the legs it is 

 short, oblique, and intermixed with a sparse pubescence. Head 

 longitudinally rugose, the posterior fourth reticulate. Scrobes deep, 

 smooth, and shining, faintly and vertically striate over their posterior 

 half. Mandibles longitudinally striate, quadridentate. Thorax and 

 2nd node rugoso-reticulate, the reticulations on the node closer and 

 finer than on the thorax. Declivity of the epinotum and the 1st node 

 smooth and shining. Head and thorax moderately shining between 

 the reticulations. Abdomen nitidulous, very finely reticulate or 

 alutaceous ; here and there the reticulations are closer and stronger, 

 forming more or less rosette-like points. Head as wide behind as 

 long, not much narrowed in front, the posterior margin convex, the 

 posterior angles sharp. Eyes moderately large, placed behind the 

 middle of the sides. The frontal carinae and the scrobes extend 

 back as far as and end at the posterior angles. Median area of 

 clypeus margined laterally by a raised line or carina, between them
