In conclusion it is worth mentioning the influence that man has 

 had upon the distribution of some of the Orthoptera of the Chilcotin 

 district. Before this country was settled, the whole of the tableland 

 (geophilous campestrian location) was thickly covered with bunch- 

 grass, and although undoubtedly somewhat colder than the river valley 

 slopes (phytophilous campestrian location), I believe that the Orthop- 

 teran fauna was very similar in the two localities.
