  Specimens 
  sometimes 
  occur, 
  probably 
  only 
  in 
  sandy 
  stations, 
  in 
  which 
  

   the 
  insects 
  are 
  of 
  a 
  nearly 
  uniform 
  flavous 
  color, 
  often 
  tinged 
  slightly 
  

   with 
  ferruginous, 
  giving 
  a 
  very 
  different 
  general 
  appearance 
  from 
  the 
  

   normal.
