660 Annals of the South African Museum. 



The basal half of the scape reddish ochreous, the tarsi dark brown. 

 The sculpture sharper and more coarse on the head and thorax, and 

 clearly so on the abdomen, which is finely striate transversely and 

 sprinkled with wide, shallow and piligerous punctures. The pilosity 

 is longer, much more abundant on the thorax and abdomen than in 

 the type of the species, (the pronotum has from 13-16 hairs on each 

 side), the tips of the hairs pointed. The pubescence is also more 

 abundant and distinctly longer. The two faces of the epinotum are 

 much more oblique, their junction hardly angular.

%, 6*5-8-2 mm. Black, tarsi dark brown. Pubescence decumbent, 

 very short and inconspicuous, almost confined to the legs and antennae. 

 Pilosity sparse, long, fairly pointed and not thick, of a dirty whitish 

 colour, more abundant on the abdomen than elsewhere, and absent 

 from the legs and antennae. Shining, sculpture of the usual type of 

 the sub-genus, but the anterior half of the head is finely and clearly 

 reticulate and subopaque, and the vertex sparingly and shallowly 

 punctured. The mesonotum has 3 or 4 large piligerous- punctures 

 on each side, and there are also a few on the pronotum. Head 

 subquadrate, a trifle longer than wide, moderately narrowed in front, 

 the sides fairly convex, the posterior margin straight or nearly so, 

 the posterior angles widely rounded. Clypeus very obtusely carinate, 

 with a very short lobe, the anterior margin moderately convex. 

 Mandibles slightly shining, strongly punctured, 6-dentate. The scapes 

 extend beyond the hind margin by about the length of the 1st joint 

 of the flagellum. Eyes placed just behind the middle of the sides. 

 Frontal carinae sinuate, widely divergent behind. Pronotum flattened 

 above, its dorsum joining the sides in a very rounded angle and 

 forming indistinct shoulders in front, twice as wide as long. Pro- 

 mesonotal suture sharply defined. Mesonotum slightly tumid in front. 

 Meso-epinotal suture ill-defined in the middle. Epinotum with a 

 fairly distinct dorsal face, slightly flattened, oblique lengthwise, and 

 about one-third longer than wide. It joins the declivity in a fairly 

 distinct but wide angle; the declivity is two-thirds as long as the 

 dorsum. Scale of petiole convex in front, flat behind, the edge 

 convex from side to side. Tibiae cylindrical, not setose below.
