DisTKiBUtiON OF Gl. longipemiis, Covti. ■ 



Of this species I have been able to examine a series of seven 

 examples as follows : — ■ . 



1 (J (type of the species), River Uelmal, Boran Galla 

 Country, N.E. Africa, June, 1893 (CapL Vittorio Bottego), lent 

 by the Museo Civico di Storia Naturale di Genova, through the 

 courtesy of Dr. R. Gestro ; 1 ? (^'yp^ of the above description 

 of the ,$ ), West Somaliland, 23-25. vi. 1895 (0. 7. A. Peel) [O.] ; 

 3 (J (J (including type of above re-description of the (J ), 1 ? , 

 Somaliland, precise locality unknown (Th. Greenfield) ; 1 <J , 

 Uganda Railway, British East Africa — ? Kiboko River, or 

 Sabaki River near its junction with the Tsavo River, 1898 

 ( Vet.-Capt. A. J. Maslam). 



The above list of localities shows that the present species is 

 the Tsetse-fly of Somaliland and the adjacezit regions, but that 

 its range overlaps that of Gl. fusca, Walk., somewhere in the 

 vicinity of the Sabaki River. A field -note by Mr. Peel attached 

 to his specimen mentioned above says ; " Fly -belt sharply defined 

 from Biermuddo to Boholo Deno."

 from Capt. Haslam's letter of IG. 4. 1898. 



It will have been observed that, of the seven specimens of 

 Gl. longipennis examined, all but two are males. One of the 

 male specimens collected and presented by Mr. Greenfield was 

 evidently taken in the act of sucking, since its abdomen is 

 swollen and distorted owing to its containing decomposed blood, 

 while there is a globule of coagulated blood at the tip of the 

 proboscis. , 



Synonymy and Affinities. 



Glossina longipennis, Corti, is perhaps the best and most 

 easily characterised species of the genus. A year before the 

 species was actually described I had noted the specimens pre- 

 sented to the British Museum by Mr. Greenfield as a new species 

 allied to Gl, fusca, Walk. It is uixfortunate that at the end of
