DISTRIBUTION OF GLOSSINA TACHINOIDES. 41 



recorded from the Congo Free State or the Uganda or East 

 Africa Protectorates, its range evidently extends right across 

 Africa, since G. tachinoides is not only reported to exist in 

 German East Africa,* but has also been met with in vSouthern 

 Arabia,t thus being so far as is known the only existing species 

 of Glossina found outside the African continent and certain of 

 the islands oif the coast. 



As regards the French possessions in AVest Africa, G. tachi- 

 noides has been identified by Professor Laveran from Casamance, 

 Marigot de Bayla, Bignona, and Carabane in Senegal ; the 

 Lower Rio Nunez, Boke, and the Tinkisso River in French 

 Guinea ; the banks of the Bani and Shai-i Rivers in the French 

 Sudan ; and the Mayo-Kabbi region in French Congo4 



Of this species the British Museum (Natural History) at 

 present possesses 4:4: ^ ^ and 69 9 ? j the details with reference 

 to which are as follows : —

* Apud Stuhlmann (Arbeifcen a. d. Kais. Gesundheitsamte, Bd. xxvi, 

 Heft 3, p. 301 (1907) ), G. tachinoides occurs in German East Africa, in the 

 vicinity of Amani, at the foot of the Usambara IMountains. 



t C/. Captain R. Markham Carter, I.M.S., " Tsetse-Fly in Arabia": 

 British Medical Journal, November 17, 190G, p. 1393. This does not 

 invalidate the generalisation that existing Tsetse-flies are confined to the 

 Ethiopian Region, since the southern portion of Arabia belongs zoo-geo- 

 graphically to the region in question. In addition to G. tachinoides, many 

 other African insects occur on the eastern shore of the Strait of I3ab-el- 

 Mandeb.
