180 Miss G. Ricavdo on 



specimens from Ashauti, Duala in Cameroons, Sierra Leone, 

 Liberia, and S. Nigeria, in I. E. E. Coll. from Knmasi. 

 Ashanti ; Nyasaland, Ibadan in S. Nigeria, and Gold Coast. 



A small black species; the tibiae paler at the extreme base 

 only, the bristles on legs black. In the female the fore 

 femora have two or three short black bristles below and soft 

 white hairs. In the male there are usually two long black 

 bristly hairs and yellow hairs. 



Length, c? 15/? 15-20 mm. 



A series of males and females from Pretoria (^Miss J. 

 Brinckei') differ slightly, the males having no black bristly 

 hairs on fore femora below, in the female there are some 

 black and white bristles; the tibiae and tarsi on their outer 

 sides have white bristles, and the tarsi some on the inside, 

 the hind femora with them above and below. Moustache 

 is white, but there are black bristles above towards the base 

 of the autennse ; they are slightly larger, measuring in the 

 males 17|-21 ram., in the females 18 ram. 



Philodicus walkeri, ? , Hicardo. 



[Asilus turiiitis, $ , Walker, List Dipt. ii. p. 407 (1849), in parte.] 



Type (female) from Sierra Leone (presented by Rev. F. D. 

 Morgan), other females from Bugama, Nigeria {Th'. Annott), 

 and Sierra Leone (Walker Coll.). 



This specimen placed with Philodicus turinus male type 

 as the female type evidently is not the same species, though 

 very nearly allied, the legs being niore largely black with 

 all black bristles ; the tibise are dull rufous on their outer 

 sides, black at the apices ; the femora are wholly dark- 

 coloured, all armed with black bristles ; the pubescence on 

 legs greyish, the oral opening with three or more black 

 bristles. 



The absence of the long yellow bristles on the fore tibiae 

 and fore tarsi distinguishes it at once from Philodicus turinus. 

 Walker's description of this latter is more than usually in- 

 accurate, no mention being made of these bristles in the 

 male type, and the assertion that the wings in the female 

 are longer than the body is incorrect. 



Length 23-27 mm. 



Philodicus fraterculus, ? , Walker.
