﻿INSECTS OF EASTERN TROPICAL AFRICA. 31 1 



Genus Hippobosca, L. 



Hippobosca hirsuta, Aust. 



Two males from the plains north-east of Lake Edward, Uganda, 16th October 

 1911, on a Avaterbuck {Cobus defassa). One of these was biting a native after 

 having escaped. 



Hippobosca hirsuta var. neavei, Aust. 



Eight males and four females were taken in the upper and mid Luangwa 

 Valley, North Eastern Rhodesia, in August 1911, all on waterbuck {Cobus ellipsis 

 prymnus). Two males were also obtained on the Lofu River, south of Lake 

 Tanganyika, in August 1908, on a puku {Cobus vardoni). 



Hippobosca capensis, Olf. 



A few individuals of this species were taken on natives in the valley of the 

 Ruaha River, German East Africa, in December 1910, and also on dogs at Voi, 

 British East Africa, in February 1912. It is specially associated with Canidae 

 and Felidae. 



Hippobosca struthionis, Jans. 



A good series of this species was taken on a wild ostrich, which was shot for 

 the purpose, near Gimba, British East Africa, in April 1911. A single 

 specimen was also captured on a native in the same neighbourhood. 



Genus Echestypus, Speiser. 



Echestypus paradoxus, Newst. 



This species seems to be a common parasite on Tragelaphine antelopes over a 

 wide area. I found it on a bushbuck at Msoro's, 50 miles west of Fort Jameson, 

 and also on greater kudu, 35 miles east of Fort Jameson, North East Rhodesia, 

 in September 1910 ; in Nyasaland, on bushbuck, near Kota Kota, in November 

 1910 ; in British East Africa, on lesser kudu, near Makindu, in April 1911. 



Genus Olfersia, Leach. 

 Olfersia ardeae, Macq. 



Two individuals of this species were taken on the Goliath Heron {Ardea 

 goliath), near Kota Kota, Nyasaland, in October 1910. 



Genus Lynchia, Weyenb. 

 Lynchia maura, Big. 



A common and almost cosmopolitan parasite of domestic pigeons. I have 

 personally taken it on these birds in Northern Rhodesia, Nyasaland and German 

 East Africa ; but it probably occurs all over Eastern Africa. 



Ornithoctona platycera, Macq. 



This is not an uncommon species on Passerine birds over a very wide area. 

 It occurs in my collection from a thrush, Turdus stormsi, Hartl., north of Lake 

 Bangweolo, North Eastern Rhodesia, in June 1908, and from a stonechat, 

 Pratincola torgiiata, L.
