  This 
  insect 
  has 
  been 
  found, 
  according 
  to 
  Bruner, 
  on 
  beets 
  and 
  

   quite 
  commonly

  the 
  beet 
  family, 
  but 
  is 
  espe- 
  

   cially 
  abundant 
  on 
  the 
  white 
  pigweed. 
  It 
  is 
  

   abundant 
  in 
  Illinois 
  and 
  is 
  extensively 
  distrib- 
  

   uted 
  over 
  the 
  United

  Bruner 
  has 
  recorded 
  (U. 
  S. 
  Bull. 
  

   22, 
  p.

  an 
  unusual 
  outbreak 
  of 
  this 
  species 
  in 
  

   company 
  with 
  the 
  large-eyed 
  plant-bug 
  {^Geo- 
  

   coris

  and 
  the 
  false 
  chinch-bug 
  {JVysius 
  

   angustatus) 
  in 
  the 
  neighborhood 
  of 
  Lincoln, 
  

   Nebraska, 
  on 
  land 
  which 
  had 
  been 
  allowed 
  to 
  

   grow 
  weeds 
  during 
  the 
  latter 
  part 
  of 
  the 
  season 
  

   preceding. 
  The 
  following 
  spring 
  was 
  dry, 
  and 
  

   swarms 
  of 
  these 
  insects 
  injured 
  seriously 
  what
