the mesonotuni rather thickly clothed with short black hairs. 

 Scutellum subopaque, with an almost obsolete longitudinal 

 impression; postscutellurn without an impressed line. Median 

 segment clothed with very short silver pubescence, and with 

 long* whitish hairs ; the segment beneath the pubescence very 

 finely transversely rugulose ; the sides of the segment sparsely 

 and shallowly punctured, with sparse black hairs. Petiole as 

 long as the second joint of the hind tarsi ; seventh tergite 

 rather broadly truncate at the apex. Sternites sparsely 

 clothed with long black hairs which become denser on the 

 sides, eighth sternite narrowly rounded at the apex, with a 

 longitudinal carina. First recurrent nervure received at 

 about three-quarters from the apex of the second cubital cell, 

 sometimes a little nearer to the apex. 



? . Sixth tergite narrowly rounded at the apex ; sixth 

 sternite convex, narrowly rounded at the apex, the hairs on 

 the sternites short and very sparse. 



Hab. Entebbe, Uganda (C. G. Gowdey), May to January; 

 N.W. shores of Victoria Nyanza (S. A. ]S J eave), September; 

 Bukoba, German East Africa (G. G. Gowdey), June. 



Nearly related to C. hiemorrhoidalis, Fabr. (volubtlis, 

 Kohl), but may be distinguished from the variety of that 

 species with black legs by the white hairs and pubescence of 

 the median segment and by the position of the first recurrent 

 nervure, which in hcemorrhoidalis is inteistital with the 

 second transverse cubital nervure ; the apical tergite of the 

 male is also much broader at the apex.

? . Clypeus and front sparsely clothed with long fulvous 

 hairs, which stand out from among the short golden pubes- 

 cence. Inner margins of the eyes parallel ; posterior ocelli 

 scarcely as far from the eyes as from each other ; eyes sepa- 

 rated on the vertex by a distance equal to the length of the 

 second joint of the flagellum plus half of the third joint. 

 Scutellum with a delicate impressed longitudinal line which 

 does not reach the base or the apex, strongly convex ; post-
