172. Miss G. Ricardo on the Asilides. 
Promachus floccosus, Kirby, Trans. Ent. Soc. Lond. p. 273 (1884) ; 
Hutton, Trans. New Zeal. Inst. xxxiii. p. 21, nota (1901) ; Ricardo, 
Ann. & Mag. Nat. Hist. (8) xi. p. 413 (1913). 
Kirby’s type, a male, is identical with this species, as 
pointed out by Hudson there was a mistake in the locality, 
there being no such place as Opabo, New Zealand, which is 
on the label—he believed it came from Opobo, W. Africa. 
This well-known species is widely distributed, specimens 
in Brit. Mus. Coll. being from Sierra Leone, Senegal, 
Uganda Protectorate, Nyasalaid, Natal, Ashanti, British 
E. Africa, and 8. Africa. 
In the I. E. E. Coll. are long series of specimens from 
Nyasaland. 
All of these have the moustache varying from black and 
white to almost wholly yellow, but none entirely black. 
A small male from Sierra Leone has the femora and 
tibie chiefly reddish yellow, also a large female from S8.E. 
Katunga, but the femora are chiefly black. 
Promachus simpsoni, sp. n. 
Type (male) and type (female) from Yapi, Gold Coast, N. 
Territories, Nov. 1915 (J. J. Simpson), and a long series of 
males and females, all in I. E. E. Coll., males and females from 
N. Nigeria (J. J. Simpson), 1912, 460, in Brit. Mus. Coll. 
A species nearly allied to Promachus poetinus, W1k., with 
redder legs, but at once distinguished in the male by the 
presence of a white tuft of hairs above the genitalia and 
the last segment of abdomen is somewhat produced below. 
In the female the ovipositor is shorter and has two spines 
at its apex. The legs are almost entirely reddish, with a 
mere vestige of a black stripe on femora. Moustache and 
beard yellow. 
Length, ¢ 19-23, 2? 17-25 mm.
