Hippoboscidee cn the British Museum. 257 
species was published in 1816 *; the paper in which Leach’s 
Species was described, though read on April 10, 1810, was 
not published until 1818. Thus, strictly speaking, von 
Olfers’s name has two years’ priority over Leach’s; but since 
Leach was certainly not responsible for the delay of eight 
years in publishing his paper, the stringency of the law of 
priority may well be relaxed in his favour in this instance, 
and the name Francillont may be allowed to stand. 
HI, Francilloni, which is well known in India and Ceylon 
as a pest of dogs, must be added to van der Wulp’s catalogue 
already referred to. The Museum collection includes speci- 
mens from Kant, near Shahjahanpur, North-West Provinces, 
India, 29. xi. 1900 (Lieut.-Col. Giles); and others from 
Trincomali and Kanthalla, Ceylon (Lieut.-Col. Yerbury). 
We also possess specimens from Japan (8. Bligh), and a 
male from Seoul, Korea, 17. vii. 1900 (Hon. EH. Scarlett), 
“caught on a Japanese dog.”” The species also occurs in 
Africa, and we have recently received a series of specimens 
from various localities, including Voi, Ndi, Mbuyuni, Ma- 
kumbu, and Samburu, in British East Africa; in addition to 
these we possess specimens from “the interior of South 
Africa,” presented in 1843 by the Earl of Derby. From 
North Africa we have specimens from Suez, Nov. 1901 (/. 
Morey). In 1901-1902 the species was obtained in Cyprus 
(Troodos, about 4500 feet, and near Ktima) by Miss D. M. 
A. Bate. It may be worth while to add that the Museum 
collection contains a female bearing the label “ Francilloni”’ 
in Leach’s handwriting, but it is impossible to say with cer- 
tainty that this specimen is the actual type. 
Hippobosca camelina, Leach: op. cit. p. 556, tab. xxvii. 
figs, 11-14.—The name Hppobosca dromedarina has recently 
been proposed by Dr. Speiser (loc. ctt. p. 176) for H. camelina, 
Rond. (nec Leach), but I venture to think that the form 
referred to is not really distinct. The British Museum col- 
lection includes a long series of specimens of H. camelina, 
Leach, as also of H. maculata, Leach, and in both of these 
species there is a considerable variation (from ferruginous to 
deep brown) in the ground-colour of the thorax. Moreover, 
as shown by our specimens, in the case of H. camelina at any 
rate, the dark and light forms may occur in the same locality. 
* Not 1815, as stated by Speiser (Joc. cit.): Hippobosca capensis was 
described in von Olfers’s pamphlet, ‘De Vegetativis et Animatis Cor- 
poribus in Corporibus Animatis Reperiundis Commentarius,’ pars i. 
(Berolini: in Taberna Libraria Maureriana), p. 101.
