  The 
  species 
  has 
  previously 
  been 
  reported 
  (under 
  another 
  name) 
  from 
  

   Lake 
  Point, 
  Salt 
  Lake 
  and 
  Salt 
  Lake 
  Valley 
  (Scudder), 
  Mount 
  Xebo 
  

   and 
  Spring 
  Lake, 
  Utah 
  (Thomas), 
  and 
  Utah 
  (Uruner). 
  

  

  The 
  contrasts 
  of 
  colorings 
  in 
  this 
  species 
  render 
  it 
  a 
  more 
  variegated 
  

   insect 
  than 
  any 
  of 
  the 
  other 
  species 
  of 
  the 
  genus, 
  particularly 
  when 
  the 
  

   buff 
  colors 
  are 
  deepest 
  and 
  bring 
  out 
  the 
  black 
  and 
  white 
  with 
  greatest 
  

   vividness.
