  It 
  was 
  first 
  recorded 
  as 
  a 
  sugar-beet 
  insect 
  by 
  Bruner, 
  and 
  on 
  account 
  

   of 
  its 
  abundance 
  and 
  its 
  fondness 
  for 
  beets 
  this 
  leaf-hopper 
  may 
  now 
  

   and 
  then 
  give 
  trouble. 
  Osborn 
  speaks 
  of 
  it 
  as 
  a 
  persistent 
  beet 
  feeder,

  and 
  in 
  the 
  sugar-beet 
  plats 
  on 
  the 
  Illinois 
  University 
  farm 
  it 
  was 
  fre- 
  

   quently 
  noted, 
  becoming 
  very 
  abundant 
  in 
  October, 
  

  

  Unlike 
  A. 
  punctata 
  it 
  prefers 
  open 
  sunny 
  localities, 
  avoiding 
  damp 
  

   shady 
  woods. 
  It 
  is 
  particularly 
  destructive 
  to 
  clover, 
  and 
  in 
  addition 
  to 
  

   sugar 
  beets 
  attacks 
  also 
  celery, 
  turnips, 
  cabbage, 
  strawberries, 
  blue-grass 
  

   (to 
  some 
  extent) 
  , 
  and 
  a 
  variety 
  of 
  weeds 
  — 
  especially 
  pigweed 
  and 
  lamb's- 
  

   quarters 
  (A?narantus 
  a.nd 
  Chenopodiunt). 
  Its 
  punctures 
  cause 
  small 
  white 
  

   spots 
  on 
  blue 
  grass 
  leaves. 
  The 
  larva 
  keeps 
  near 
  the 
  ground 
  and 
  hides 
  

   under 
  rubbish. 
  Its 
  life 
  history 
  differs 
  a 
  little 
  from 
  that 
  of 
  the 
  species 
  of 
  

   the 
  genus 
  mentioned 
  above. 
  It 
  seems 
  to 
  hibernate 
  mostly 
  as 
  an 
  adult, 
  

   under 
  various 
  sorts 
  of 
  rubbish 
  — 
  old 
  boards, 
  hay, 
  and 
  other 
  like 
  shelter. 
  

   We 
  have 
  taken 
  it 
  in 
  such 
  situations 
  in 
  December. 
  In 
  Osborn's 
  breeding- 
  

   cages 
  eggs 
  were 
  found 
  inserted 
  beneath 
  the 
  cuticle 
  of 
  the 
  clover 
  leaf 
  

   along 
  the 
  midrib 
  of 
  the 
  blade, 
  though 
  most 
  were 
  probably 
  laid 
  in 
  the- 
  

   leaf 
  sterns 
  or 
  in 
  the 
  bases 
  of 
  the 
  plants. 
  The 
  first 
  larvae 
  from 
  spring 
  

   eggs 
  appeared 
  May 
  20th, 
  and 
  began 
  to 
  mature 
  by 
  July 
  ist. 
  Later, 
  all 
  

   stages 
  could 
  be 
  found 
  together 
  until 
  on 
  the 
  approach 
  of 
  winter 
  the 
  young 
  

   all 
  gradually 
  became 
  adult.

  This 
  western 
  species 
  is 
  recorded 
  from 
  garden 
  and 
  sugar 
  beets 
  in 
  

   Colorado 
  by 
  Gillette 
  and 
  Baker 
  ('-'Hemiptera 
  of 
  Colorado," 
  p. 
  81), 
  

   and 
  also 
  from 
  Sisymbrium 
  canescens 
  and 
  alfalfa. 
  Various 
  dates 
  are 
  given 
  

   from 
  May 
  yth 
  to 
  October 
  15th. 
  The 
  life 
  history 
  is 
  not 
  known.

  This 
  largest 
  of 
  our 
  leaf-hoppers 
  was 
  found 
  on 
  sugar 
  beets 
  at 
  Urbana 
  

   during 
  the 
  latter 
  part 
  of 
  June. 
  It 
  seems 
  to 
  be 
  especially 
  a 
  grape 
  insect,
