202 TSETSE IN CAMEEOONS. 



the Tsetse are not known. It is found throughout the 

 valley of the Limpopo River, but does not come much 

 south of this, except in the eastern borders of the Trans- 

 vaal. Here it extends far south of Delagoa Bay, and 

 infests the Lobombo Mountains and the Amatonga 

 country, reaching to the confines of Santa Lucia Bay. 

 It appears to be gradually retreating northwards following 

 the big game."

A species of Glossina at Baromhi Station, Cameroons, 

 [Translation.] " On the other hand, a yellowish- 

 brown Glossina is distinguished by its particularly painful 

 bite (Stich). This fly is found chiefly in the primeval 

 forest, and pursues and persecutes human beings with 

 downright revolting cunning and pertinacity. When one 

 is bitten a small drop of blood at once exudes and the 

 place becomes much swollen."

 Barombi, or Elephant Lake, a little to the south of
