$ . Head and abdomen black, thorax dark red. Head, thorax, 

 and abdomen covered with erect black hairs. Head about as broad 

 as the thorax anteriorly, covered with coarse, somewhat greyish pile, 

 beneath which it is closely punctured ; mandibles acute at tip with 

 a small preapical tooth on their inner margins ; antennae opaque, 

 the scape covered with pile similar to that on the front and vertex, 

 1st joint of the flagellum very short, 2nd twice as long as the 3rd ; 

 eyes oval, rather small, equidistant from the occiput and the base 

 of the mandibles. Thorax : strongly punctured above, the sides 

 excavate and smooth. Seen from above, the thorax is narrow and 

 rounded anteriorly, emarginate at the sides and distinctly broadened 

 posteriorly ; the dorsal surface convex, passing evenly and roundly 

 into the posterior vertical face, which is slightly concave in the 

 centre ; legs black, covered with whitish hairs ; the calcaria and the 

 single row of spines on the intermediate and posterior tibiae white ; 

 claws simple, pale reddish -brown. Abdomen somewhat densely 

 covered with short black pile, beneath which it is closely punctured; 

 1st segment immaculate beneath, longitudinally carinate, with a 

 single somewhat deep emargination in the middle, 2nd segment with 

 two rounded pubescent spots side by side placed closer to the base 

 than to the apex of the segment, the lateral edges of the dorsal plate 

 with a short longitudinal line of red ; 3rd segment with a transverse 

 band of dense white pubescence broadly interrupted in the middle, 

 apex of the dorsal and the apices of the 2nd to the 5th ventral 

 segments conspicuously fringed with white hairs, pygidial area 

 clearly defined, flat and finely punctured. 



Length $ 8 mm. 



Described from the single $ taken in cop. at Buluwayo 

 by Mr. G. A. K. Marshall. 



From the $ of 3f. leucopyga, it can be distinguished by 

 the shape of the thorax, which in leucopyga has the sides 

 parallel, and by the proportion of the joints of the flagellum 

 of the antennae.
