Distribution. Thi.s species was based upon a single 

 female example from Berbera (NE. Africa), but recorded also 

 from Sso-oraadu, a locality on tlie caravantrack from ZeyUi 

 to Addis-Abbeba in Shoa (Kraepelin, 1903), and from the 

 Kenia-district, whence only two specimens were hitherto obtained; 

 they ware found ainder logs and dry palm leaves in the thoru- 

 bush country north of Guaso Nyiro river at Njoro)) during 

 a Swedish zoological Expedition to British East-Africa 1911 

 (Lonnberg, 1912). B. polystictus is undoubtedly closely allied 

 to B. eniini\ the specific value of this form of scorpion is very 

 doubtful.
