DISTIUBUTION OF GLOSSINA PALPALIS. 75 



Distribution of Gl. palpalis, Rob.-Desv. 



The present species, which is the Glossina longipalpis of 

 authors (nee Wiedemann), has a wide range in West Africa, 

 and, as is shown by the localities of the specimens before 

 me, in its distiibution from north to south extends at least 

 from the Gambia (var. tachinoides) to the Congo, though from 

 our knowledge of the extremely local occurrence of Glossina 

 morsitans in South Africa, as indicated by the familiar term " fly- 

 belt," it is not at all likely that GL palpalis will be found to 

 occur everywhere on the West Coast. As to the range of the 

 species inland all that can be stated at present is that var. 

 tachinoides was found by Dr. (afterwards Sir) John Kirk on the 

 Zambesi — the j^recise locality is unfortunately unknown. Gl. 

 palpalis, however, is not the only species found in West Africa, 

 since, as will be shown later, 6?/. pallicera. Big., Gl. fusca, Walk., 

 Gl. longipalpis, Wied., and Gl. morsitans, Westw., also occur 

 there.
