KESEAECn IN BRITISH WEST AFKIC'A. 



321 



At Bokaui the only blood-suckiiig Hies seen during my vwit in October were 

 G. iacldiwides and Haeuiutopotu lacessens, but Rlnpicephulus simiis and Claiwcc- 

 pludus cants were very abundant on dogs. G. tachinoides was also obtained at 

 Gudu Gudu. Dr. J. W. Archibald, who was stationed at Bokani and afterwards 

 at Jebba, sent in a number of species, but as the only data accompanying them 

 were "Jebba and Bokani 1910 " it is impossible to determine the precise locality 

 of each. It may be advisable, however, to enumerate them here : — Myzoinyiu 

 fiinesta, M. costalis, Munsonioides anifurmis, Gloss'uiu jKilpalis, G. tachinoides, 

 G.submorsitans, Tabunus higuttatas croceus, T. fasciatas, T.latipcs, T.ditaeniatus, 

 T. par, Tahanus sp. nov. and Hippohosca maculata. 



{d-) Zungeru and its Environs- 



The town of Zungeru (locally known as the cantonment) is situated on the 

 right bank of the River Kaduna, and is the seat of administration of Northern 

 Nigeria. I do not propose to enter into a lengthy description of this town, but 

 shall draw attention to only a few of the most important points in connection 

 with the blood-sucking insects which occur there, and the possible causes of their 

 existence and abundance. It might be well, therefore, to enumerate these at 

 this stage.
