ocelli in an almost equilateral triangle, the posterior pair 

 almost as far from each other as from the eyes. Antenna? 

 stout, the second joint of the ilagellum not as long as the 

 third and fourth combined, the fourth as broad as long. 

 Pronotum smooth ; mesonotum shining, closely punctured, 

 more closely anteriorly than posteriorly, clothed with black 

 hairs ; scutellum and postscutellum almost smooth, pleurae 

 closely punctured. Median segment closely and finely 

 punctured, the sulci defining the basal area almost obsolete, 

 a broad longitudinal depre-sion on the middle of the dorsal 

 surface not quite extending to the base. Abdomen smooth 

 and shining, sixth tergite delicately longitudinally striated ; 

 sternites sparsely punctured. Fore metatarsus with seven 

 spines. Cubitus of the hind wing originating distinctly 

 beyond the transverse median nervure. 



<$ . The sculpture throughout rather stronger than in the 

 female, scutellum sparsely punctured, median segment 

 finely punctured-rugose ; tergites smooth and shining, the 

 seventh tergite with large scattered punctures. Fourth 

 joint of the flagellum distinctly longer than broad. 

 Distance between the eyes on the vertex about equal to the 

 length of flagellar joints 2-4. 



Hab. Mt. Kokanjero, S.W. of Eigon, Uganda Protectorate, 

 6400 ft. (S. A. Neave), August 1911 ; Ruwenzori, 7000- 

 8000 ft. (Scott Elliot). 



Males with the black pubescence somewhat shorter are in 

 the collection from Ankole-Toro Border, E. of Lake George 

 (S. A. Neave), October 1911 ; Nandi Escarpment, 5800 ft. 

 (S. A. Neave), May 1911 ; and Uchwezi Forest, British E. 

 Africa (£. A. Neave), March 1912. 



Philanthus niyrohirtus, subsp. calvus, subsp. n. 



Specimens of both sexes from the Luangwa Valley, N.E. 

 Rhodesia, are without the long black hairs on the head and 

 thorax, but do not differ appreciably otherwise. For this 

 form 1 suggest the above subspecific name. The female is 

 without yellow marks on the vertex. This approaches 

 P. stecki, Schulz, but the eyes are a little further apart on 

 the vertex, the posterior ocelli in stecki being distinctly 

 nearer to the eyes than to each other. Specimens apparently 

 not distinct specifically from calvus from W. Africa 

 (Gambia, Gold Coast, Togo, and N. Nigeria) often have 

 eight spines on the fore metatarsus. These seem to be 

 distinct from P. camerunensis , Tullgr., in which the posterior
