microscopically graiiulose; the orbital bristles three, lonj?, 

 but not strong. Anterior sterno-plcural short. Anterior 

 median liind tibial bristle slif^htly basad of the antero-dorsal 

 one, both basad of middle. Eyes covering almost the entire 

 side of head. 



Length 3 mm. 



One female, Obuasi, Ashanti, !■. viii. 1907 ( W. M. Graham). 



Caricea pilifemur (Stein). 



One pair i/« copula and one female, Ulundi, Natal, ix. 189G, 

 5(K)()-()5()0 feet (G. A. K. Marshall). 



A very distinctly shining black species, which is distin- 

 guished, as stated in the key, by the markings on the 

 abdomen. 



Caricea semifumosa (Stein). 



A very striking species. Entirely black, densely grey- 

 ])ruinesceut, the thorax not vittate, and the abdomen with 

 the fuscons paired spots fused. Wings white on basal half, 

 black on apical half. Median long bristles on hind tibia at 

 same height ; fore femur with a series of fine short antero- 

 ventral bristles on basal two-thirds which are longest at 

 base ; anterior sterno-pleural bristle long ; frons very 

 narrow, not over one-Hfth as wide as head at centre in male, 

 the bristles fine and short ; longest hairs on arista as long as 

 width of third antcunal segment. 



Length 1- mm. 



Four males, AVillow Grange, Natal (/?. C. Wroughton) . 



Caricea semialba, sp. u. 



Male and female. — A larger species than the last and 

 more robust, the wings of female not infuscated, and those 

 of male rather ineonsjjicuously so. Other distinguishing 

 characters as stated in key. The eluetotaxy of the legs is 

 similar to that of the last species, but the bristles are longer 

 and stronger, and those on antero-ventral surface of hind 

 femur are more numerous, forming an almost complete, 

 if sparse, series. The frons is about as wide as length of 

 antenna, while in semifumosa it is distiiictly narrower ; 

 lower and anterior sterno-pleural bristles much shorter than 

 upper. 



[iCngth 4-5 mm. 



Ti/pe, male, allotvpe, and two male paratypes, Ulundi, 

 Natal, ix. 1890, 5()U0-tJ500 feet (G. A. K. Marshall). One 

 female paratype. Willow (irange, Natal {li. C. ]\'roughton).
