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



Tabanus pullulus, Aust. 



Two females of this recently described species were taken on the Upper Shire 

 and on the southern shores of Lake Nyasa, in February and March 1910. It 

 much resembles T. claritibialis, to which it is closely allied, both in habits and 

 distribution. The female eyes are dusky and unicolorous. 



Tabanus thoracinus, P. de B. 



A very widely distributed species, occurring in high ground as well as low, 

 and in forest as well as in open country. It is especially abundant in Uganda. 

 The series I obtained comprised 128 males and 202 females. The female eye is 

 a brilliant green (a slightly deeper colour than that of T. par) ; the large- 

 facetted area of the male eye is " old gold," with a greyish iridescence in some 

 lights. 



Tabanus obscuripes, Eic. 



Of this somewhat scarce species I captured 2 males and 2 females near the 

 north-east shore of Lake Bangweolo, between Luwingu and the mouth of the 

 Chambezi River, in October 1908. In November 1910, I took some 10 females 

 in German East Africa, in the Usaniiu and Usagara districts. The female has 

 dark purplish eyes, not fjrcca like those of T. thoracinus, but the upper area of 

 the male eye is of a golden bronze colour, as in that species. 



Tabanus par, Walk. 



This small species has a wide distribution throughout Tropical Africa. My 

 collection, from all sources, contains 82 males and 48 females. The eye of 

 the Q is brilliant emerald green, somewhat paler than that of T. thoracinus 

 when compared in life. The upper large-facetted portion of the male eye is of a 

 shining golden colour. 



Tabanus medionotatus, Aust. 



This new species is represented by 6 Q Q , taken between Luwingu and the mouth 

 of the Chambezi River, near the north-east shores of Lake Bangweolo, Northern 

 Rhodesia, October 1908. Also by a single Q from the Upper Kalungwisi 

 Valley, September 1908. 



Tabanus liventipes, Sure. 



This seems to be an uncommon species. It is only represented in my collection 

 by a female collected near Petauke, in the Luang wa Valley, Northern 

 Rhodesia, in January 1905, and by another from the Upper Shire Valley, taken 

 in February 1910. The eyes of the female are green ; the male is unknown. 



Tabanus ditaeniatus, Macq. 



Although this species ranges practically throughout Africa, and even as far as 

 India, it seems to be nowhere very abundant in East Africa. It is more common 

 in low country and near the larger rivers or lakes than elsewhere. The Q eye is 

 a pale vitreous yellow, with dark spots. In the g the large-facetted area is paler, 

 of a more silvery colour and seems to lack the spots.
