there can be no doubt that Tabanus brumpti, Surcouf , is a perfectly 

 good species, distinguishable from T. ruficrus, Pal. de Beauv., by its 

 clearer wings and more brightly coloured tibiae, and by the fringe 

 of hair on the hind tibiae being ochraceous-rufous instead of black. 

 In the male the greyish bloom on the abdomen, which is so 

 noticeable a feature in the female, appears to be wanting. Of T. 

 brumpti, the range of which extends at least from the Sierra Leone 

 Protectorate to Uganda, the Museum possesses a male from Bo, Sierra 

 Leone Protectorate, October, 1908 (Dr. H. E. Arbuckle, W.A.M.S. 

 presented by the London School of Tropical Medicine), and four 

 females. Of the latter, one is from the Benue River, Northern 

 Nigeria, August, 1907 (J. Brand), while the other three are from a 

 banana plantation at Kampala, Uganda, 1903 (Colonel Sir David 

 Bruce, C.B., R.A.M.C., F.R.S.).

Of this species, the type of which is from the San Benito River, 

 French Congo, the Museum Collection contains a single female, from 

 Odut, Southern Nigeria, May, 1906 (G. C. Dudgeon). Nothing is 

 known of the habits of the species, and nothing further can be said 

 as to its distribution.
