front than behind, the sides moderately convex, the hind margin 

 straight. Distinct demiscrobes present; the frontal carinae extend 

 backwards as far as the posterior margin of the head, 2nd-8th joints 

 of the flagellum wider than long. Clypeus with a strong median 

 carina, and two weaker and broken lines on each side of it. 

 Mandibles finely striate, armed with three distinct teeth in front, 

 feebly denticulate behind. Sides of pro-mesonotum indistinctly 

 marginate, the shoulders of the pronotum obtusely angular. Thoracic 

 sutures obsolete. Dorsum of epinotum oblique, a little longer than 

 wide, as long as, or a little longer than the declivity. The epinotal 

 spines are longer than the interval between their bases, but shorter 

 than the dorsum of the epinotum, divergent, acute and fairly oblique. 

 Petiole similar to that of Joffrei, but the dorsal face of the 1st node 

 is fairly distinct from the short posterior face, not forming a con- 

 tinuous curve as in Joffrei. The femora are but slightly swollen in 

 the middle. 



$ . 3*5 mm. The colour of the thorax is rather darker than in 

 the $ . Pronotum reticulate-rugose, the sides and posterior third 

 of the mesonotum longitudinally striate, the anterior two-thirds 

 smooth. The dorsum of the epinotum is almost obsolete, being in 

 very nearly the same plane as the declivity. The epinotal spines are 

 parallel and nearly horizontal. Dealated. Otherwise like the £ .

" The U differs from that of the type Species in having the thorax 

 smooth, from the anterior margin of the pronotum as far as the 

 epinotal spines." Port Elizabeth. (Dr. H. Brauns.) 



I possess some specimens from this locality, collected by Dr. Brauns, 

 which appear to belong to this variety. The dorsum of the thorax is 

 in greater part smooth, but there are distinct, though fine, short 

 rugae near the lateral and anterior margins of the pro-mesonotum, 

 and on the basal half of the epinotum. The size is a little larger, 

 3 - 4 mm.
