Kirhy'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, wiiich is 

 on the label — he believed it came from Opobo, W. Africa. 



This well-known species is widely distributed, specimens 

 ill Brit. Mus. Coll. being from Sierra Leone, Senegal, 

 Uganda Protectorate, Nyasalai d, Natal, Ashanti, British 

 E. Africa, and S. Africa. 



In tlie I. E. E. Coll. are long series of specimens from 

 Nyasalaiid. 



All of the?e have the moustache varying from black and 

 white to almost wholly yellow, but none entirely black. 



A small male from Sierra Leone has tlie femora aud 

 tibiae chiefly reddish yellow, also a large fenaale from S.E. 

 Katunga, but the femora are chiefly black. 



Promachus simpso7ii, sp. n. 



Type (male) and type (female) from Yapi, Gold Coast, N. 

 Territories, Nov. 1915 (J. J.Simpso?i), and a long series of 

 males and females, all in I. E. E. Coll., males and females fioui 

 N. Nigeria (J. J. Simpson), 1912, 4G0, in Brit. Mus. Coll. 



A species nearly allied to Promachus poeiinus, Wlk., 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.
