256 Mr. E. E. Austen on 
the Hippoboscide: in the British Museum (Natural History). 
Within the last few weeks the Museum has received from 
Mr. F. D. Godman the final instalment of the great collection 
of Central American Diptera worked out in the ‘ Biologia 
Centrali-Americana,’ including the Hippoboscide described 
by the late F. M. van der Wulp (cf Biol. Centr.-Amer., 
Diptera, vol. ii. pp. 429-432, April 1903). An examination 
of these shows that van der Wulp’s determinations in many 
cases need revision, as indicated below under the genera 
concerned. The present paper is printed in the hope that 
it may prove of some slight service to other workers at this 
interesting family of Diptera, which, although previously 
much neglected, has within the last few years been so 
fortunate as to receive attention at the able hands of 
Dr. P. Speiser. 
Hippososca, Linn. 
Hippobosca equina, L.—In this species the amount of 
yellow on the scutellum varies very much, and sometimes 
this portion of the thorax is nearly all yellow, as shown in 
certain specimens in the British Museum collection from the 
neighbourhood of Biskra, Algeria (Rev. A. H. Haton). The 
colour of the scutellum, therefore, cannot be used as a 
character to distinguish H. equina, L., from H. Prancillont, 
Leach, for which purpose the colour of the veins of the wings 
must be relied upon. 
This species must be added to the list in van der Wulp’s 
‘ Catalogue of the Described Diptera from South Asia’ (The 
Hague: Martinus Nijhoff, 1896), since the Museum collec- 
tion contains a male from Celebes (purchased from E.Gerrard, 
jun., 1896) and a female from “ Bengal ” (no further details) 5 
while a male from Kalewa, Upper Burma, March 1893, “ found 
on pony ” (Capt. H. Y. Watson), apparently represents a pale 
variety. A male from Noumea, New Caledonia, June 1900 
(J. J. Walker, R.N.), was recently presented by Mr. G. C. 
Champion. 
Hippobosca Francilloni, Leach: Memoirs of the Wernerian 
Natural History Society, vol. ii. (1818), p. 554, tab. xxvi. 
figs. 8-10.—According to Speiser (Zeitschr. £. Hymenopt. u. 
Dipt., ii. Jahrg. Heft 3 (1 May, 1902), p. 174), this species 
(of which ZH. canina, Rond., is a synonym)=W/. capensis,

is in the Museum fiir Naturkunde, Berlin. Von Olfers’s
