252 ZAMBEZIAN ZOOLOGY 



Conversely, I am aware of extensive areas populous 

 with game of many varieties wherein the Tse-tse 

 has not been noted ; areas, be it understood, where 

 buffaloes although not permanently present occur 

 at certain times of year. 



There are, of course, many points relating to the 

 curious predilection of this insect for one part of 

 the country in preference to another apparently 

 equally favourable to its development which are 

 still imperfectly, if at all, understood ; but that it 

 should be dependent upon any kind of mammal for 

 its sustenance, or that, as some persons of extreme 

 views have stated, the beautiful and interesting 

 game families should be exterminated in order that 

 the Tse-tse should thus perforce succumb to a 

 death by famine, is a theory so inconsistent with 

 the views of well-qualified observers, who have 

 approached the question with the advantage of a 

 more scientific environment than was possessed in 

 the days to which Mr. Selous' remarkable memory 

 enables him to throw back his still active mind, 

 that of a truth one is forced to the conclusion 

 that their enthusiastically expressed views must 

 have been largely the outcome of imperfect

 the largest, ughest, and in many ways the most 

 singular. In addition there are the Bush-pig 

 {Potamochcerus chcerapotamus), and another of 

 whose identity I am uncertain, but which may be 

 a slight variation of the bush variety mentioned. 



Of the first species, I suppose there is probably
