Hippoboscides tn the British Museum. 259 
ranging from Somaliland to Algeria and from Aden to Trebi- 
zond. We also have a female from Chaman, S. Afghanistan, 
28. vii. 1880, “ collected at mess, at 11.0 P.M.” (Col. Swinhoe), 
so that the species constitutes a further addition to van der 
Wulp’s South Asia catalogue. 
Hippobosca maculata, Leach: loc. cit. p. 553, tab. xxvi. 
figs. 11-13.—This species must also be added to van der 
Wulp’s catalogue. The Museum possesses a series of some 
twenty-seven examples, chiefly from various localities in 
India and Ceylon, but also including specimens from Arabia 
and Egypt, and I have recently seen a female from W. Africa 
(Abutshi, R. Niger). The type of the species—a female, 
labelled in Leach’s handwriting—is also in the Museum 
collection. 
Hippobosca rufipes, von Olfers: De Vegetativis et Ani- 
matis Corporibus in Corporibus Animatis Reperiundis Com- 
mentarius, pars i. (1816), p. 101.—In addition to a consider- 
able number of specimens of this species from various localities 
in South Africa, the British Museum possesses a female from 
Bembe Mines, Angola, W. Africa, lat. 7° 22’ S. (J. J. Mon- 
tetro), and a male and female from the Congo (A. Curror). 
FHippobosca struthionis, Janson: in Miss EK. A. Ormerod’s 
‘Notes and Descriptions of a Few Injurious Farm and Fruit 
Insects of South Africa’(London: Simpkin, Marshall, & Co., 
1889), p. 56, fig. 23.—This species is of peculiar interest, 
since it was described as parasitic on ostriches in Cape Colony. 
It is true that the typical specimen of HHippobosca rufipes, 
von Olfers, was found by Lichtenstein on an ostrich at the 
Cape of Good Hope, but it was suggested by von Olfers that 
the true host may have been the quagga, which was fre- 
quently to be met with among the ostrich-flocks (¢f von 
Olfers, loc. cit.). In the case of H. struthionis, however, the 
flies were stated to be in “ thousands” on ostriches at Mount 
Stewart, Cape Colony, in May 1886, and to have increased 
in numbers to such an extent in the two preceding years as 
to render it probable that the ostrich-feather industry might 
suffer owing to the irritation to the birds caused by the dies 
(cf. Ormerod, op. cit. p. 58). Whether Hippobosca struthionis 
is still a pest on South-African ostrich-farms I am not aware, 
but that the species is not confined to South Africa is shown 
by the fact that we have recently received a series of speci- 
mens from British East Africa, viz.: two males and two 
females from Makumbu and Athi-ya-Mawe, Feb.—-May 1899 
(C. S, Betton); and a female from Ukamba, Machakos
