Extract

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 journey I visited Yendi, formerly an important German post in Togoland, thence going to Salaga and Kete-Krachi, where I crossed the Volta and proceeded to join the main north road at Atabubu (Tabobo).

Of the few species of Odontomyia whose life-history is known the larvae live in mud or damp earth or among decaying leaves and therefore the statement that Dr. Simpson's species is a parasite of Glossina would appear to need verification.—Ed.]
