fairly dull, abdomen moderately shining. Sculpture, pilosity etc. as 

 in the type species; posterior tibiae finely setose below. Head as 

 wide as long, more convex-sided than in the type species, including 

 the closed mandibles subcordate, the posterior margin much more 

 concave and with the occipital lobes more prominent. Clypeus ob- 

 tusely carinate. Frontal carinae wider apart behind than in the type 

 species. Thorax wide, the epinotum less compressed, the dorsum 

 and declivity of about equal length, and meeting at an angle of 

 about 120°. Convexity of thorax greater than in the type species, 

 L. = 3H., highest at about the middle of the mesonotum. Abdomen 

 less elongate. Otherwise like the type of the species. 



^ media, 10"5 mm. Dull ochreous, the head and antennae reddish 

 ochreous, the abdomen like that of the Qj. but with the dark bands 

 on the first two segments less distinct. Head quite one-third longer 

 than wide, the sides almost straight or only very feebly convex, 

 hardly narrower in front than behind, the posterior margin almost 

 straight and much wider than in the type of the species. The scape 

 extends beyond the hind margin by about two-fifths of its length. 

 Convexity of thorax, L. = 3 H. Otherwise like the § media of the 

 type of the species. 



^ minor, 9*5 mm. Like the § media, but the head is ochreous 

 only. The anterior margin of the lobe of the clypeus is straight, 

 not arcuate as in the type of the species. Frontal carinae wider 

 apart behind. Otherwise like the ^ minor of the type.

"§ major, 5£- lines, (ca. 12 mm.). Extremely like maculatus, which 

 it may be ; the antennae and head as in that species, the legs entirely 

 ferruginous; the abdomen entirely black. In other respects the same 

 as maculatus. 



§ minor. This insect differs from the small § of maculatus; the 

 head is of a different form, being narrowed slightly behind the eyes 

 and is more sharply emarginate behind; the scale of the peduncle 

 is more elongate and pointed at the apex ; the abdomen entirely 

 black and the legs red. Notwithstanding the differences pointed out, 

 this species will probably prove to be a variety of maculatus. Port 

 Natal." 



This race is unknown to me; it has been recorded from S. W. 

 Africa, the Cape Flats and Kammagas, Little Nainaland.
