  This 
  locality 
  was 
  peculiar 
  as 
  

   compared 
  with 
  those 
  farther 
  south, 
  in 
  the 
  fact 
  that 
  but 
  little 
  wheat 
  

   or 
  rye 
  was 
  to 
  be 
  found 
  in 
  the 
  region, 
  and 
  the 
  chinch-bugs 
  were 
  con- 
  

   sequently 
  largely 
  compelled 
  to 
  resort 
  to 
  oats 
  and 
  grass 
  in 
  spring 
  for 
  

   the 
  deposition 
  of 
  their 
  eggs 
  and 
  for 
  their 
  own 
  earliest 
  food. 
  A 
  sin- 
  

   gle 
  field 
  of 
  wheat 
  visited 
  May 
  5, 
  was 
  growing 
  luxuriantly, 
  with 
  here 
  

   and 
  there 
  a 
  spot 
  dry 
  and 
  unthrifty. 
  Chinch-bugs 
  were 
  much 
  more 
  

   abundant 
  here 
  than 
  in 
  oats, 
  and 
  were 
  doing 
  a 
  considerable 
  amount 
  

   of 
  damage, 
  least, 
  of 
  course, 
  in 
  the 
  lower, 
  damper 
  portions 
  of 
  the 
  

   field. 
  They 
  were 
  not 
  only 
  clustered 
  about 
  the 
  roots, 
  but 
  scattered 
  

   far 
  up 
  on 
  the 
  growing 
  plant. 
  Rye 
  fields 
  were 
  usually 
  about 
  equally 
  

   infested 
  with 
  the 
  wheat. 
  In 
  the 
  oats 
  a 
  comparatively 
  small 
  number 
  

   of 
  bugs 
  were 
  on 
  or 
  in 
  the 
  earth 
  upon 
  the 
  roots 
  of 
  the 
  plants. 
  Eggs 
  

   were 
  abundant 
  everywhere, 
  and 
  scattered 
  dead 
  adults 
  were 
  found 
  in 
  

   all 
  the

  Cxood 
  rains 
  May 
  24 
  and

  roads 
  and 
  fields 
  were 
  

   now 
  dry. 
  Bugs 
  very 
  abundant 
  in 
  two 
  wheat 
  fields 
  visited, 
  and 
  flying 
  

   freely. 
  Those 
  on 
  the 
  ground 
  were 
  running 
  actively 
  about 
  among 
  

   the 
  wheat, 
  and 
  many 
  were 
  dead 
  in 
  the 
  ditch 
  by 
  the 
  roadside 
  adjacent. 
  

   Young 
  just 
  hatched 
  and 
  in 
  the 
  first 
  and 
  second 
  stages 
  were 
  very 
  

   abundant, 
  reddening 
  the 
  wheat, 
  which 
  was 
  worse 
  infested 
  than 
  in 
  

   fields 
  further 
  south 
  — 
  probably 
  because 
  small 
  acreage 
  of 
  wheat 
  led 
  

   to 
  closer 
  concentration. 
  Many 
  of 
  the 
  bugs 
  were 
  dead 
  with 
  Sporo- 
  

   trichum 
  but 
  none 
  seen 
  with 
  Entomophthora, 
  and 
  no 
  dead
