90 DISTIITBUTION OF GLOSSINA BREYIPALPIS. 



DiSTRiBUTiox OF G. hvevipcdpis, Newst. 



Glusnina hrevipaJins, to which the name G. fusca has hitherto 

 been appHed in error, is the common large Tsetse-fly in many 

 parts of South-Central and East Africa, but, although found in 

 the Congo Free State, it does not, so far as our present know- 

 ledge goes, occur in West Africa proper. Reliable records and 

 the data attached to the specimens available for examination 

 show that G. hrevipalpis exists in Portuguese East Africa, the 

 Nyasaland Protectorate (where it has a wide distribution, being 

 abundant at certain seasons in and near the Songwe Valley, at 

 the north end of Lake Nyasa, besides occurring in and on the 

 edge of the Elephant Marsh, near the Lower Shire River, to the 

 south of the lake*), North-Eastern Rhodesia,t German East 

 Africa (where it is found in large numbers in the vicinity of 

 Amani — at the foot of the Usambara Mountains — and also 

 elsewhere f), the (British) East Africa Protectorate, the Katanga 

 district of the Congo Free State, and in Angola. 



It has not been thought necessary to give precise details 

 concerning the localities and dates of capture of the whole of 

 the 359 specimens examined, the majority of which were 

 collected in the Nyasaland Protectorate by Drs. Sanderson 

 and Davey, to whose papers (quoted above) reference should 

 be made for further information. The data as to the speci- 

 mens received from countries other than Nyasaland are as 

 follows : —

 Railway, 1908 (received from LI. E. W. Bevan, M.R.C.V.S.).

 vicinity of Hargreaves (Chutika's), and in very small numbers, see
