A NOTE ON HIPPOBOSCA MARTIN AGLIA BEDFORD 
(DIPTERA, HIPPOBOSCIDiE) 
By J. Bequaert 
Harvard Medical School and School of Public Health, 
Boston, Mass. 
In my second revision of the Hippoboscidse (1939, Psyche, 
XL VI, pp. 70-90), I accepted Hippobosca martinaglia Bed- 
ford (1939) as a valid species on the basis of the original 
description and figure. Shortly before his death, the late 
Dr. G. A. H. Bedford promised to send me a paratype, but 
unfortunately he was never able to do so. Dr. R. du Toit, 
Veterinary Research Officer at Onderstepoort, has since 
gone to considerable trouble in order to clear up the iden- 
tity of this parasite. It was not possible thus far to trace 
Bedford’s types, which are either mislaid or lost. In July, 
1940, Dr. du Toit was, however, able to obtain specimens 
of a Hippobosca collected on the type host (Impalla, 
JEpyceros melampus) at the type locality (Bar R Ranch, 
Swaziland) of H. martinaglia. The male and female, which 
he sent me of this lot, agree well with Bedford’s descrip- 
tion and they are obviously his species. At the same time 
it is impossible to separate them from Hippobosca fulva 
Austen. Bedford’s H. martinaglia I regard therefore as a 
synonym of H. fulva. The name martinaglia should be 
removed from the list of valid species of Hippobosca , which 
now number eight only. In the key of my 1939 paper, 
couplet 6 should be discarded, the second alternative of 
couplet 5 running directly to couplet 7. 
The wing of H. martinaglia is exactly like that of H. fulva , 
the second longitudinal vein being about as long as the api- 
cal section of the third longitudinal (Bedford’s figure is 
incorrect in this respect) , and the basal section of the third 
longitudinal vein is bare. There is only one pair of vertical 
bristles on the head. The scutellum bears nine preapical
