The following specimens are in the British Museum 

 collection : — 



Type (female) from British Central Africa, 1906 {E. L. 

 Ehoades) ; one female from Gadzima, Mashonaland, Dec. 

 1895 {O. A. K. Marshall), 1903. 17; one female from

 one male from Estcouit, Natal, Jan. 1897 [G. A. K. 

 Marshall), 1903. 17. 



This species is very nearly related to Tahinus ditceniafus, 

 Macq., and may be easily confused with it at first sight, but 

 is a distinct species, recognized by the black coxas and 

 almost wholly blackish femora and by the absence of any 

 grey tomentum in the centre of the median black stripe of 

 abdomen. 



Length 12-14 mm. 



The antennae are slightly darker at the apex. The ey 



face, palpi, and forehead similar to those of 2\ difmniatus, 

 with the two typical black spots on the forehead. There is 

 no trace of grey triangles on the black stripe of abdomen in 

 the females. The yellow legs are darker, the femora all 

 being black for two thirds of their length, the apical third 

 alone being yellow. The clear wings have a short appendix. 

 Tlie male has yellowish eyes, brown below, the facettesall 

 equal, except those on the lower third of eye which are 

 smaller, no stripe apparent. Palpi club-shaped, yellow, 

 transparent. The abdomen has the apex more widely black 

 than in the females and a grey tomentose stripe is visible 

 on the median black stripe ; the legs are similar to those of 

 the females, but the femora are almost wholly black, only 

 their extreme apex being yellow.
