﻿100 ERNEST E. AUSTEN — NOTES ON AFRICAN BLOOD-SUCKING MIDGES 



insects occur in large numbers they cause quite a considerable amount of 

 annoyance, and the natives, who are more or less indifferent to the attacks 

 of Tsetse-flies and Sand-flies, are particularly afraid of the bites of these blood- 

 suckers, for which they have characteristic names signifying ' tormentors ' or 

 ' scourges.' " 



The following are the localities, dates of capture, etc., of the specimens of this 

 species received since the publication of ' Illustrations of African Blood-Sucking 

 Flies ' ; the records in all cases refer to females, since no examples of the 

 opposite sex have yet reached England. 



Southern Nigeria: Yaba, Lagos, May, 1909 (one specimen only), "caught 

 in veranda of bungalow " (with examples of Gulicoides distinctipennis, sp. n. — see 

 below, and many specimens of the West African race of C. milnei, Austen — 

 Dr. W. M. Graham, W.A.M.S.) ; Bende, 27.viii.1911 (Dr. P. H. Macdonald, 

 W.A.M.S. : — in possession of the Entomological Research Committee). 



Angola : San Salvador, Portuguese Congo, January and May, 1909, "biting 

 morning and evening " {Dr. Mercier Gamble). 



Uganda Protectorate : Mpumu, Chagwe, July, 1910 ; shore of Lake 

 Victoria, August, 1910 (Captain A. D. Fraser, R.A.M.C.). 



Gulicoides brucei, Austen. 



Culicoides brucei, Austen, Ann. Mag. Nat. Hist., Ser. 8, Vol. iii, March 1909, 

 p. 282 ; ' Illustrations of African Blood-Sucking Flies,' p. 6, PI. I, fig. 2 

 (1909). 

 In this species the wing-markings may be described as consisting of dark spots, 

 blotches, and streaks upon a light ground, being therefore markedly different in 

 character from those exhibited by, at any rate, C. milnei and the first two of the 

 new species described below, in all of which the ground-colour of the wings is 

 dark while the spots are light. Culicoides brucei is still known only from the 

 Uganda Protectorate, where (in the vicinity of the Mianga River) the type and 

 para-types were obtained in July, 1903. It is to be hoped that collectors will 

 keep a special look-out for this easily recognisable midge, which, like its con- 

 geners, is doubtless common enough in places where it occurs. 



Gulicoides milnei, Austen. 



Culicoides milnei, Austen, Ann. Mag. Nat. Hist. Ser. 8, Vol. iii, March 1909, 



p. 283 ; ' Illustrations of African Blood-Sucking Flies,' p. 6, PL I, fig. 1 



(1909). 

 This species, which was originally received from the East Africa Protectorate, 

 and was subsequently (' Illustrations of African Blood-Sucking Flies,' loc. cit.) 

 recorded by the author as occurring in Uganda, is also found in the Anglo- 

 Egyptian Sudan and in Southern Nigeria, where it is apparently represented by 

 a local race, which differs from the typical form in being considerably smaller, 

 and in having the two distal light costal spots on the wings much closer together. 

 Specimens of C. milnei, which may be regarded as being intermediate between 

 the typical form and the West African or Southern Nigerian race, have been 

 captured in the Uganda Protectorate by Drs. McConnell and Duke. The
