at least as far as the Gambia. The possibility that Tabanus 

 variatus, which is represented in the Museum Collection by forty- 

 three females, is in reality a form of Tdbanus tceniola, Pal. de Beauv., 

 has already been alluded to in the notes on that species.* The 

 localities, etc., of the Museum specimens are as follows. "Interior 

 of South Africa," before 1843 (presented by the Earl of Derby). 

 Orange River Colony : Bloemfontein, 1898 ( Wilman). Nyasa- 

 land Protectorate : Blantyre District, May, 1905, and Zomba, 

 April, 1906 (Dr. J. E. S. Old) ; Upper Shire River, January 14th and 

 20th, and Nkata Bay, Lake Nyasa, April 15th, 1906 (E. L. Rhoades). 

 German East Africa : precise locality unknown (collected on Captain 

 Speke's Expedition to the Sources of the Nile presented by Lord 

 John Russell, 1864). Uganda : Ankole, May 9th, Buddu and 

 Bulamwezi, 1903 (Colonel Sir David Bruce, C.B., R.A.M.C., F.R.S.) ; 

 Junda, Buruli, " hi banana plantation near R. Seziwa," and 

 Buruli, " in patch of forest on Lukoge River, half-way between 

 Junda and Kisiliza," 1903 (S. C. Tomkins) ; Kisembara, February 

 10th (Dr. Cuthbert Christy) ; Wadelai, November, 1904 (Captain 

 E. D. W. Greig, I. M.S.) ; Albert Lake District, 1905 (Dr. O. H. 

 Pooley) ; Northern Usoga, 1906 (received from Dr. A. D. P. 

 Hodges). Abyssinia : Dembratcha, Godjam, April May, 1902 

 (E. Degen). Angola : Bihe and Benguella, 1904 (Dr. F. Creighton 

 Wellman). Northern Nigeria : Loko, north bank of Benue River, 

 March, 1907 (Dr. B. McGahey, W.A.M.S.). Gambia, 1906 (Dr. E. 

 Hopkinson, D.S.O.). 



This species also occurs on the islands in the Gulf of Guinea. 

 According to R. Greeff,t " T. serratus, Lw." (i.e. T. variatus, Walk.), 

 is very widely distributed upon St. Thomas I., but rare on Rolas : 

 it is said to attack human beings, especially natives, with peculiar 

 pertinacity. 



It may be noted that Tabanus variatus, Walk., perhaps = T. 

 Sagittarius, Macq., but that without making an examination of 

 Macquart's type a definite decision as to this is impossible.
