  McNeill 
  found 
  it 
  in 
  Illinois 
  only 
  on 
  high 
  sandy 
  ground 
  where 
  the 
  

   sole 
  vegetation 
  was 
  Cenchrus, 
  and 
  the 
  grrtS!^ho])pers 
  were 
  "colored 
  so 
  

   nearly 
  like 
  the 
  yellow 
  sand 
  that 
  they 
  were 
  difficult 
  to 
  see 
  when 
  only 
  

   two 
  or 
  three 
  feet 
  away."

  certainty,
