﻿296 S. A. NEAVE — NOTES ON THE BLOOD-SUCKING 



specimens were taken in Central Angoniland and South Nyasa districts about 

 the same time by Drs. A. H. Barclay and J. B. Davey, but the species does not 

 seem to be a common one. 



Tabanus unitaeniatus, Ric. 



A single female was taken on the Lower Zambesi, in February 1904 ; others 

 in the Luangwa Valley, in January 1905, and on the Upper Shire and the 

 south-west shores of Lake Nyasa, in February and March 1910. 



Tabanus variabilis, Lw. (PI. X, fig. 7.) 



Fair numbers of this species were captured in various localities. It seems to 

 frequent Avoodland or moderately open country, not forest. The eyes in both 

 sexes are dusky. 



Tabanus atrimanus, Lw. 



This fly seems to be common and widely distributed all over Eastern 

 Tropical Africa, except Uganda. In my experience, it chiefly frequents well 

 wooded streams. The <5 cf seem nearly as common as the QQ, my collection 

 containing 38 <S d and 46 Q Q . The eyes of both sexes in life are a dusky 

 purplish. 



Tabanus velutinus, Sure. (Fl. X, fig. 6.) 



A good series of 32 males and 38 females was taken in British East Africa at 

 Masongaleni, Kibwezi, and Makindu, on the Uganda Railway, in April 1911. 

 The insect was evidently just hatching out at that time. The eyes are banded 

 with crimson and green like those of T. sharpei. 



Tabanus neavei, Aust. (PL X, fig. 5.) 



This is a fairly common forest-haunting species in Uganda, and it also occurs 

 in the forests of North Kavirondo, in the Nyanza Province of British East 

 Africa. My collection contains iu all 34 males and 15 females. 



Tabanus sharpei, Aust. 



Though nowhere abundant this species seems to have an extensive range in 

 Northern Rhodesia, Nyasaland and German East Africa, and small numbers of 

 both sexes were taken in various localities in those countries. The female eye is 

 of a deep claret colour, with a median green band. On the male eye the same 

 colouring is reproduced below, but above in the large-facetted area is replaced by 

 an iridescent mauve ground with a dusky band. 



Tabanus wellmanii, Aust. 



Three females were captured on the high plateau south of Lake Tanganyika, 

 Northern Rhodesia, at 4,500 ft., in August 1908, and three more on the Chisinga 

 Plateau, in the Kalungwisi district, in September 1908. 



Tabanus pertinens, Aust. 



This recently described species is a common one in Eastern Africa, chiefly in 

 low-lying river valleys, and fair numbers, in some cases large numbers, were 

 taken in Northern Rhodesia, German and British East Africa. In all, 58 males
