DISTKIBUTION OF GLOSSIXA PALLICERA. :57 



Distribution of G. paUlcera, Bigot. 



Glossina pallicera is a West African species, which is 

 apparently one of the rarest of the Tsetse-flies at present known, 

 and of which the area of distribution extends, at any rate, from 

 the Sierra Leone Protectorate to French Congo. The following 

 are the details with reference to the specimens in the National 

 Collection': — Sierra Leone Protectorate : \ $ , Firo, 17. iv. 1909 

 {Major A. Pearse, E.A.M.G.). Liberia: 1 9 , Tappoima, 11. v.,

 B.A.M.C). French Ivory Coast : 1 ^ {the type of the species),

 Kumasi, 19. vii. 1907, "caught on horse on polo ground" 

 (forwarded by Dr. T. E. Bice, S.M.O. ; presented by Dr. W. M.

 Sovithern Nigeria: 1 ^, Ojogbo, Benin City, 16. iii. 1910

 Committee). 



As regards French Congo, a specimen of G. pallicera is stated 

 by Professor Laveran to have been taken on the Benue River 

 (Mayo-Kabbi region), in January or February, 1907, by 

 Dr. Ducasse.* In Ashanti, according to Dr. Graham, the 

 species appears to be " extremely local." 



Bionomics. 



For the few details that can be given under this heading we 

 are indebted to the observations made in Ashanti, in 1907, by 

 Dr. W. M. Graham, who informed the author that he always 

 found the fly in the "bush," where it "does not settle on the 

 ground, but sits on the upper side of leaves." Writing of this 

 Tsetse as met with by him on the N'Kawi Road, Kumasi, 

 Dr. Graham says : — " G. pallicera was found in a narrow bush 

 path, bordered by short bushes, but free from tall trees. . . . 

 This fly appeared strictly localised. I found it only on this
