Psyche 
[June-Sept. 
(King, 1911). — Kenya Colony: Witu, Lamu and Wangi, 
without host, cotype. — Nyasaland : Upper Shire River, south 
of Lake Malombe, off Strepsiceros strepsiceros (Davey and 
Newstead, 1921) . — Cape Province : Caffraria, without host, 
cotype. 
Specimens Examined. — Gold Coast : Sawla, off Cephalo- 
phus sp. ; Banda N’Kwanta, off Cephalophus rufilatus ; Ban- 
dewa, off Ourebia ourebi quadriscopa; Guripe, off Cephalo- 
phus sp. (all J. J. Simpson). — Anglo-Egyptian Sudan: 
Darraba, Dinder River, off Ourebia ourebi montana (G. M. 
Allen) ; Bongo, River Nile, Equatoria, off Abyssinian blue 
duiker, a race of Cephalophus caerulus (Neal Weber). — 
Uganda: Bulukatoni, West Nile, off Tragelaphus scriptus 
(C. R. S. Pitman). 
Host Relationships. — E. sepiaceus has been definitely 
recorded from five distinct antelope hosts. The red-flanked 
duiker, Cephalophus rufilatus Gray, is strictly West African 
(Upper Guinea to northeastern Belgian Congo). The blue 
duiker, Cephalophus caerulus (Ham. Smith), occurs in sev- 
eral races in South and East Africa, as far north as the east- 
ern Sudan. The distribution of the bushbuck, Tragelaphus 
scriptus (Pallas) and of the greater kudu, Strepsiceros 
strepsiceros, are discussed under E. paradoxus, as these an- 
telopes harbor both species of Echestypus. The ouribi, 
Ourebia ourebi (Zimmermann) , occurs in several races in 
the savannas of most of Africa south of the Sahara. 
Distribution. — E. sepiaceus is now known with certainty 
from the Gold Coast, the Anglo-Egyptian Sudan, Uganda, 
Kenya Colony and Nyasaland. The only record for South 
Africa proper is based on the old specimen from “Caffraria”, 
which Speiser included among the types. Perhaps it might 
be well to examine this fly more carefully, to see whether it 
is strictly cospecific with the cotype from Kenya Colony. 1 
Like E. paradoxus, E. sepiaceus is evidently an insect of the 
savanna and plains country of Central and East Africa, but 
it extends much farther west, across the Sudan. It should 
be looked for in French Guinea and Senegambia. 
Synonymy. — E. sepiaceus was originally based upon two 
1 In case the Caffraria specimen was of a different species, I herewith 
restrict the name sepiaceus to the form represented by the type from 
Witu, Lamu and Wangi.
