carinae sinuate, divergent, extending back to the posterior fifth of 

 the head. The scrobes are shining, with a few transverse striae ; the 

 longitudinal ridge, which divides the scrobe into two parts for the 

 reception of the scape and flagellum respectively, does not reach 

 the posterior end of the scrobe, the outer half of the scrobe not well 

 defined. Eyes large, prominent and very convex, their margins 

 angular below, placed in the middle of the sides of the head. The 

 scape extends to the posterior fifth of the head ; 1st joint of the 

 flagellum twice as long as wide, 2nd-7th joints wider than long. 

 Thorax only slightly constricted between the meso- and epinotum, 

 thoracic sutures entirely absent. The thorax is convex transversely in 

 front and above, and in profile, moderately convex in front. The 

 epinotal spines are very acute, directed upwards and outwards, rather 

 long, a little longer than the interval between their bases. The brow 

 of the declivity, between the spines, is transversely striate ; the 

 declivity marginate at the sides, the raised margins continued into the 

 short and blunt episternal teeth. First joint of the petiole with 

 the peduncle half as long as the node. The latter, seen from above, 

 has the anterior margin almost semicircular, the posterior margin 

 moderately convex ; it is three-fifths wider than long. The 2nd node 

 is transversely oval, very convex from front to back, a little wider than 

 the 1st node, and twice as wide as long. Abdomen one-quarter longer 

 than wide, the sides not very convex. 



Matopo Hills, S. Rhodesia. (S.A.M., R.M., G.A. colls.), type in 

 my collection. 



This species is allied to gabonensis, Andre, and mucidus, Forel 

 From the former it differs by its smaller size, colour, the shape of the 

 1st node and the divided scrobes ; from mucidus it differs by the 

 straight anterior margin of the clypeus, by the angulated lower 

 margin of the eye, by the deep scrobes, the shining head and thoi'ax, 

 and by the hairs, which are all trifid, not divided into six or more 

 branches as in mucidus. Quite distinct from Eminii and Rothschildi, 

 Forel. 



T. Hepburni, n. sp. 



^ . 2"3-2 - 8 mm. Colour as in Constanciae. Pilosity whitish, 

 trifid, less dense than in Constanciae, particularly on the head. Sculp- 

 ture of the head and thorax as in that species, but the reticulations a 

 little closer. The nodes of the petiole reticulate, the 2nd not less 

 strongly than the 1st. Abdomen shining, very sparsely but distinctly 

 punctured, the punctures on the basal fourth shallow and foveiform. 

 Head a little longer than wide, hardly narrowed in front, the hind
