Distribution. This species has a very wide area of 

 distribution, but only in East Africa; namely, it occurs in 

 Uganda ^), in the British and German east-african colonies, in 

 Mozambique and Natal. Jomachus politus has been described 

 from Mombasa, but afterwards it was obtained in several lo- 

 calities of the southern part of British East Africa: at Maziwa 

 Mitatu, Machuma, Mbuyuni, Samburu (Pocock 1898, p. 499), 

 at Simba, Voi, Bura, Tembu and near the Tzavo river (Birula 

 1914 and 1915); according to Kraepelin (1913, p. 185) this 

 species extends from British East Africa southAvards along the 

 sea-coast into German East Africa (from Tanga to Lindi and 

 Mikindani); in the southern part of the same country it was 

 obtained further inland at Livale, Barikiwa and Langenburg 

 near the lake Nyasa. The Expedition obtained several speci- 

 mens of various age and both sexes at Voi-Bura 24 — 25 VII 

 (? juv.), Tembu 14 VITl (9 juv.), and Tzavo 14—15 VIII 

 (c? semiad. and 4 $ ad.).
