The following report is based on a tour which extended from September 1915 to 

 February 1917, but included in it are also some observations made during a few 

 months residence in 1914. 



The area comprised lies partly in the Northern Territories of the Gold Coast, and 

 partly in Togoland (see Map, Bull. Ent. Res., V, p. 32). It extends from 8° N. to 

 9° 45' N. and from 0° 15' E. to 2° 30' W. My headquarters were at Yapi on the 

 River Volta about 28 miles south-west of Tamale, the capital of the Northern 

 Territories. I have already described in a previous report* the nature of the country 

 and the type of vegetation, so need not repeat them here. I examined the whole of 

 the Volta from Yapi to Yeji by canoe, and then followed a sinuous route on my return 

 journey, keeping as close to the River as possible. The country between Yapi and 

 Daboya, a large town with an important ferry on the Volta, was traversed on several 

 occasions. From Daboya I went to Bole and made my temporary headquarters at 

 Larabanga, the centre of the game and Glossina submorsitans area. Here I spent 

 several weeks under canvas in three separate localities in the bush. On my homeward
