mouth of Lusangazi River, 1-3. ix. 1910 (S. A. Neave); type of Q from 
Zungeru, Northern Nigeria, November, 1910 (J. J. Simpson); both specimens, 
as well as a series of para-types from various localities, presented to the British 
Museum (Natural History) by the Entomological Research Committee. 
Within the last twelve months, some hundreds of specimens of this species, 
chiefly collected by Messrs. Simpson and Neave, have been received by the 
Entomological Research Committee from the countries mentioned. In Northern 
Nigeria, Mr. Simpson, who, like other collectors in the same colony, has hitherto 
only met with the female, took Tabanus pertinens in large numbers on the polo 
ground at Zungeru, in November, 1910; additional specimens, collected at the 
same time and place, were received by the Committee from Dr. J. W. Scott 
Macfie. Other Northern Nigerian localities at which the species was met with by 
Mr. Simpson are :—Kateri (2. xii. 1910), Kumbaku and Kogin Sirikin Pawa (6, 7. 
xii. 1910), the railway-crossing over the Kaduna River (10. xii. 1910), and Izon 
(15. xii. 1910). One specimen, taken on the Benue River in January, 1910, was 
received from Dr. C. E. 8S. Watson, W.A.M.S., and a female from Anka, Sokoto 
Province, 24. xii. 1910 (Dr. J. Mc. Dalziel, W.A.M.S.), is in the possession of 
Dr. J. H. Ashworth, of Edinburgh University. 
In the Anglo-Egyptian Sudan, three females of J. pertinens were taken at 
Kadowah, Mongalla Province, 21. i. 1911, by Mr. H. H. King.
