This exceedingly striking species, which has hitherto been 

 met with only in Uganda, North-Eastern Rhodesia, and the 

 Katanga District, Congo Free State, is represented in the 

 National Collection by four females, three of which are from 

 Unyoro, Uganda, half-way between Masindi and the Murchison 

 Falls, January, 1907 (the late Dr. W. A. Densham), while the fourth 

 is from Fwambo, near the south-east end of Lake Tanganyika, 

 North-Eastern Rhodesia, 1896 (W. H. Nutt). The late Dr. Densham 

 hi whose honour the species was named, supplied the following 

 field-note concerning Tabanus denshamii, as met with by him in 

 Uganda : " I saw this fly for the first time in January, 1907, 

 half-way between Masindi and the Murchison Falls. In its flight 

 and manner of alighting it resembles Tabanus tcsniola, Pal. de Beauv., 

 and I overlooked the first that appeared. I found it in several 

 camps in the neighbourhood, but its distribution seems very local. 

 The natives say that it is an elephant fly, but I shot an elephant 

 in the vicinity, and saw no biting flies at all on or near it."
