  damp 
  shady 
  ground

  Melanophis 
  bivittatus 
  Say. 
  

  

  This 
  speciesjcommon 
  in 
  Illinois,is 
  confined 
  mainly 
  to 
  the 
  Mississippi 
  

  

  Valley, 
  not 
  occurring 
  on 
  the 
  

   Atlantic 
  or 
  Pacific 
  slopes 
  or 
  in 
  

   the 
  extreme 
  northwest. 
  It 
  

   may 
  be 
  recognized 
  at 
  once 
  

   by 
  the 
  yellowish 
  dorsal 
  stripes 
  

   on 
  each 
  side 
  of 
  the 
  middle, 
  

   along 
  the 
  angle 
  between 
  the 
  

   back 
  and 
  side. 
  It 
  has 
  attacked 
  

   beets 
  in 
  low 
  grounds 
  or 
  beside 
  

   rank 
  growths 
  of 
  grass 
  or 
  clover, 
  but 
  has 
  never 
  been 
  seriously 
  injurious 
  

   to 
  that 
  crop. 
  

  

  The 
  eggs 
  are 
  placed 
  in 
  any 
  compact 
  soil, 
  such 
  as 
  old 
  roads, 
  closely- 
  

   cropped 
  pastures, 
  and 
  prairie 
  sod. 
  Adults 
  usually 
  begin 
  to 
  appear 
  

   about 
  July 
  ist. 
  Eggs 
  are 
  apparently 
  laid 
  in 
  September, 
  and 
  have 
  been 
  

   observed 
  to 
  hatch 
  in 
  March.

  This 
  is 
  the

  the 
  most 
  abundant 
  

   of 
  its 
  kind 
  in 
  fields 
  of 
  beets. 
  It 
  closely 
  resembles 
  the 
  western 
  destructive 
  

   grasshopper 
  {Melanoplus

  and 
  

   also 
  another 
  species 
  of 
  the 
  genus 
  

   {atlanis^ 
  which 
  occurs 
  in 
  Illinois 
  but 
  

   which 
  is 
  much 
  less 
  generally

   than
