  It 
  was 
  especially 
  injurious 
  to 
  corn 
  near 
  New 
  Holland, 
  Illinois, 
  late 
  

   in 
  May, 
  1898. 
  It 
  often 
  collects 
  on 
  beets 
  and 
  other 
  garden 
  plants, 
  and 
  

   injures 
  strawberries, 
  apple 
  grafts, 
  potatoes, 
  turnips, 
  radishes, 
  cabbages, 
  

   lettuce, 
  and 
  mustard. 
  It 
  is 
  said 
  to 
  prefer 
  plants 
  of 
  the 
  cruciferous 
  

   family, 
  .but 
  purslane 
  is 
  a 
  favorite 
  with 
  it. 
  It 
  is 
  often 
  mistaken 
  for 
  the 
  

   chinch-bug. 
  It 
  is 
  commonly 
  reported 
  to 
  winter 
  as 
  an 
  adult, 
  and 
  we 
  

   have 
  taken 
  it 
  under 
  the 
  spreading 
  leaves 
  of 
  dock 
  in 
  December 
  and 
  by 
  

   sweeping 
  as 
  early 
  as 
  April 
  nth. 
  On 
  the 
  other 
  hand, 
  both 
  Webster 
  and 
  

   Osborn 
  have 
  reported 
  the 
  pairing 
  of 
  adults 
  in 
  November, 
  and 
  Mr. 
  Web- 
  

   ster 
  believes 
  that 
  he 
  found 
  its 
  eggs 
  at 
  this 
  season 
  under 
  Euphorbia, 
  

   where 
  it 
  had 
  taken 
  shelter. 
  From 
  this 
  he 
  supposes 
  that 
  it 
  probably 
  

   hibernates 
  in 
  the 
  egg, 
  the 
  young 
  hatching 
  in 
  tlje 
  spring. 
  Osborn 
  has 
  

   found 
  the 
  eggs 
  among 
  the 
  blossoms 
  of 
  pigweed 
  {Amarantus 
  retroflexiis). 
  

   We 
  have 
  bred 
  the 
  imago 
  by 
  May 
  i6th 
  from 
  young 
  collected 
  May 
  nth. 
  

   The 
  number 
  of 
  generations 
  annually 
  is 
  not 
  certainly 
  known, 
  but 
  there 
  are 
  

   apparently 
  at 
  least 
  two, 
  and 
  very 
  likely 
  three. 
  

  

  If 
  insecticides 
  become 
  necessary 
  for 
  these 
  insects 
  diluted 
  kerosene 
  

   emulsion 
  may 
  be 
  used. 
  The 
  usual 
  precautions 
  of 
  clean 
  culture 
  and 
  

   the 
  destruction 
  of 
  rubbish 
  during 
  the 
  fall 
  and 
  winter 
  should 
  of 
  course 
  

   be 
  taken. 
  

  

  THE 
  SQUASH-BUG 
  FAMILY. 
  

  

  Coreida. 
  

  

  Two 
  species 
  of 
  this 
  widespread 
  and 
  abundant 
  family 
  may 
  receive 
  

   mere 
  mention 
  here 
  because 
  of 
  the 
  possibility 
  rather 
  than 
  the 
  certainty 
  

   of 
  their 
  being 
  injurious 
  to 
  the 
  beet. 
  Corizus 
  lateralis, 
  a 
  yellowish 
  in- 
  

   sect 
  about 
  a 
  quarter 
  of 
  an 
  inch 
  long, 
  with 
  small 
  spots 
  on 
  the 
  wings 
  and 
  

   head, 
  and 
  resembling 
  in 
  shape 
  the 
  common 
  squash-bug, 
  is 
  not 
  even 
  

   known 
  certainly 
  to 
  feed 
  upon 
  plants. 
  It 
  is 
  fairly 
  common 
  in 
  beet 
  fields 
  

   late 
  in 
  the 
  season, 
  and 
  the 
  nature 
  of 
  the 
  reports 
  of 
  its 
  occurrence 
  on 
  

   other 
  vegetation 
  makes 
  it 
  likely 
  that 
  it 
  is 
  of 
  vegetarian 
  habit. 
  '- 
  Acan- 
  

   thoceriis 
  galeator 
  is 
  mentioned 
  here 
  because 
  of 
  Bruner's 
  statement 
  that 
  

   he 
  has 
  found 
  it 
  several 
  times 
  on 
  beets 
  in 
  Nebraska. 
  This 
  is 
  also 
  shaped 
  

   like 
  a 
  common 
  squash-bug, 
  but 
  is 
  much 
  larger, 
  with 
  greatly 
  swollen 
  

   thighs 
  and 
  slender 
  tibiae. 
  The 
  back 
  is 
  brownish 
  gray, 
  and 
  the 
  wing 
  

   membrane 
  nearly 
  black. 
  It 
  is 
  widely 
  distributed 
  and 
  occurs 
  on 
  various 
  

   kinds 
  of 
  vegetation, 
  and 
  has 
  been 
  reported 
  as 
  destructive 
  to 
  the 
  orange 
  

   in 
  Florida. 
  

  

  Corizus 
  lateralis 
  Say. 
  

  

  Too 
  little 
  is 
  known 
  of 
  the 
  habits 
  of 
  this 
  common 
  insect 
  to 
  permit 
  

   it 
  to 
  be 
  included 
  positively 
  among 
  injurious 
  species, 
  but 
  as 
  it 
  occurs 
  not 
  

   infrequently 
  in 
  beet 
  fields 
  late 
  in 
  the 
  season 
  together 
  with 
  other 
  species 
  

   of 
  its 
  genus, 
  it 
  may 
  be 
  mentioned 
  here 
  at 
  least 
  as 
  a 
  hint 
  to 
  the 
  student.

  and
