158 MR. CLAUDE MORLEY ON AFRICAN 



S only. — The t3'pe occurred by the Yak River on the southern 

 edge of the Kakumga Forest at between 4800 and 5300 feet 

 towards the end of May 1911, in British East Africa. 



Subtribe Amblypygini. 



Amblyteles. 



This genus, as established by Wesmael (Nouv. Mem. Acad. 

 Bruxelles, 1844, p. Ill) has, like his Ichneumo7i, been subdivided 

 by Thomson into three genera, of which the typical one is well 

 represented by thirty-seven African species, all from the north 

 or south of the Continent except three ; Tosquinet had one from 

 Sierra Leone ; Szepligeti described one (Bull. Mus. Paris, 1907, 

 p. 137) from East Africa; and another, captured by the Kili- 

 manjaro Expedition, in 1910, for the synonymy of which cf. Roman 

 (Entom. Tidskr. xxxi. 1910, p. 144). Setania Cameron (Ann. 

 ISTat. Hist. vii. 1901, p. 483) is already known to be identical 

 with the present genus.
