front. Dorsum of the thorax almost straight, widely and shallowly 

 impressed in the middle. Dorsum of epinotum much longer than 

 wide, moderately convex, much longer than the declivity. Epinotal 

 spines small, acute and nearly as long as the interval between them ; 

 the episternal spines as long and as acute as the upper ones. 

 Petiole, particularly the 1st segment, shaped as in Blochmanni, i. sp., 

 and also similarly curved. Second node somewhat longer, nearly as 

 long as wide (the 1st node is much longer than wide). Shining. 

 Head, thorax, and petiole irregularly and feebly reticulate-rugose. 

 Abdomen quite smooth. Pilosity moderate, yellowish ; the pubescence 

 almost decumbent and very sparse. Tibiae, femora, and scapes with 

 almost decumbent pubescence. Yellowish-red to reddish-yellow. 

 Mandibles and tarsi a paler yellow. Abdomen brownish.

" £. 3 - 7-41 mm. Closely allied to Blochmanni, Forel, from 

 which it may be distinguished by having the whole body, legs and 

 scapes covered with short, erect and reddish-yellow hairs. Those 

 on the legs and scapes are very short, somewhat truncate at the 

 apex and slightly oblique. The head is still more emarginate behind 

 than in the Blochmanni, and has the sides straighter. A little more 

 shining than • in Blochmanni, but sculptured as in race continentis 

 of that species, reticulate or reticulate-punctate, with some distinct 

 but sparse punctures on the head and thorax. The thorax has also 

 some coarser and more accentuated longitudinal rugae ; on the head 

 these are finer, and mostly in the middle. The petiole has some 

 reticulate and very coarse rugae. Abdomen subopaque, only finely 

 reticulate. Rusty-red, with posterior half or two-thirds of the 

 abdomen brown. Otherwise like Blochmanni. 



"Lake Kabwe, Katanga. (Dr. Bequaert)." 



Although this species has not yet been recorded from our region, 

 I include it here, as it is likely to be found within the same.

^ . 3 mm. Much smaller than the type of the species. Yellowish- 

 red (burnt sienna), the legs, antennae and mandibles dark yellow, 

 somewhat - reddish. The head is shorter than in the type, being 

 barely one-sixth longer than wide (mandibles excluded), the
