  of 
  common 
  thistle 
  (Coquillett, 
  1883), 
  berries 
  of 
  wild 
  grapes. 
  (Bruner, 
  1895), 
  grape 
  

   tendrils 
  and 
  blossoms, 
  seed 
  bunches 
  of 
  sumac, 
  leaves 
  of 
  magnolia, 
  phylloxera 
  lice 
  and 
  

   their 
  galls 
  (Marlatt, 
  1896), 
  and 
  moths 
  bred 
  from 
  flower 
  heads 
  of 
  thorough 
  wort 
  or 
  boneset 
  

   and 
  Ambrosia 
  trifida 
  have 
  been 
  classed 
  with 
  the 
  grape-berry 
  moth 
  in 
  collections. 
  

  

  In 
  all 
  of 
  the 
  rearings 
  of 
  allied 
  moths 
  made 
  by 
  Kearfott 
  and 
  Slinger- 
  

   land, 
  viteana 
  was 
  not 
  obtained 
  from 
  any 
  plants 
  other 
  than 
  the 
  grape. 
  

   This 
  is 
  also 
  true 
  of 
  the 
  rearings 
  made 
  at 
  North 
  East, 
  Pa., 
  during 
  the 
  

   investigations 
  of 
  grape 
  insect 
  pests 
  which 
  have 
  been 
  conducted 
  there 
  

   from 
  1907 
  to 
  1911 
  by 
  the 
  Bureau 
  of 
  Entomology. 
  It 
  is 
  therefore 
  

   reasonably 
  safe 
  to 
  state 
  that 
  this 
  insect 
  confined 
  its 
  feeding 
  and 
  

   reproduction 
  to 
  the 
  blossom 
  clusters 
  and 
  berries 
  of 
  the 
  wild 
  and 
  the 
  

   cultivated 
  grape. 
  

  

  Mr. 
  Kearfott 
  prefaces 
  his 
  paper 
  1 
  with 
  the 
  following 
  statement: 
  

  

  The 
  following 
  notes 
  are 
  from 
  breeding 
  records 
  extending 
  over 
  the 
  past 
  four 
  years, 
  

   which 
  have 
  convinced 
  me 
  that 
  each 
  of 
  the 
  species 
  described, 
  as 
  well 
  as 
  a 
  number 
  of 
  

   others 
  waiting 
  for 
  better 
  material, 
  completes 
  its 
  entire 
  yearly 
  cycle 
  of 
  two 
  or 
  three 
  

   broods 
  on 
  a 
  single 
  food-plant 
  and 
  also 
  with 
  little 
  doubt 
  each 
  food-plant 
  supports 
  a 
  

   separate 
  and 
  distinct 
  species. 
  This 
  does 
  not 
  seem 
  unreasonable, 
  for 
  in 
  Europe 
  there 
  

   are 
  twenty 
  described 
  species 
  of 
  the 
  genus 
  Polychrosis. 
  

  

  OCCURRENCE 
  OF 
  THE 
  GRAPE-BERRY 
  MOTH 
  IN 
  DESTRUCTIVE 
  

  

  NUMBERS. 
  

  

  The 
  earliest 
  record 
  of 
  serious 
  injury 
  by 
  the 
  grape-berry 
  moth 
  in 
  

   America 
  is 
  from 
  Mr. 
  M. 
  C. 
  Read, 
  of 
  Hudson, 
  Ohio, 
  in 
  1869. 
  He 
  states 
  

   that 
  during 
  that 
  season 
  and 
  for 
  several 
  seasons 
  preceding 
  this 
  date 
  

   this 
  insect 
  had 
  been 
  very 
  injurious 
  to 
  grapes 
  in 
  vineyards 
  in 
  the 
  vicin- 
  

   ity 
  of 
  Hudson, 
  Ohio.

  Walsh 
  in 
  1869 
  states 
  that 
  several 
  persons 
  reported 
  to 
  him 
  observa- 
  

   tions 
  of 
  its 
  occurrence 
  in 
  injurious 
  numbers 
  in 
  different 
  parts 
  of 
  Mis- 
  

   souri 
  and 
  southern 
  Illinois. 
  Riley 
  makes 
  the 
  statement 
  that 
  in 
  1868 
  

   it 
  was 
  common 
  in 
  vineyards 
  in 
  Missouri 
  along 
  the 
  Pacific 
  & 
  Iron 
  

   Mountain 
  Railroad, 
  and 
  that 
  it 
  was 
  equally 
  common 
  around 
  Alton, 
  

   111. 
  He 
  was 
  also 
  informed 
  that 
  it 
  had 
  ruined 
  50 
  per 
  cent 
  of 
  the 
  

   grapes 
  around 
  Cleveland, 
  Ohio, 
  during 
  the 
  same 
  season. 
  

  

  In 
  1870 
  Townend 
  Glover 
  reported 
  it 
  as 
  occurring 
  in 
  large 
  numbers 
  

   on 
  the 
  fruit 
  of 
  grapevines 
  in 
  Maryland. 
  In 
  1882 
  Saunders 
  reported 
  

   a 
  serious 
  outbreak 
  of 
  the 
  pest 
  in 
  Canada, 
  in 
  vineyards 
  in 
  the 
  vicinity 
  

   of 
  London, 
  Ontario. 
  In 
  1885 
  Dr. 
  F. 
  M. 
  Goding 
  reported 
  it 
  as 
  being 
  

   very 
  injurious 
  in 
  vineyards 
  near 
  Ancona, 
  111. 
  Prof. 
  F. 
  M. 
  Webster 
  

   reported 
  it 
  as 
  destroying 
  50 
  per 
  cent 
  of 
  the 
  grape 
  crop 
  in 
  the 
  vicinity 
  

   of 
  Cleveland, 
  Ohio, 
  in 
  1893. 
  In 
  this 
  same 
  year 
  Prof. 
  II. 
  Osborn 
  

   reported 
  it 
  as 
  being 
  injurious 
  in 
  vineyards 
  near 
  IVs 
  Moines, 
  Iowa. 
  

   In 
  1898 
  Prof. 
  Webster 
  again 
  reported 
  it 
  as 
  being 
  very 
  destructive 
  in 
  

   the 
  vicinity 
  of 
  Cleveland 
  and 
  Gypsum, 
  Ohio. 
  In 
  L903 
  and 
  again 
  

   in 
  1905 
  Mr. 
  A. 
  F. 
  Burgess 
  found 
  it 
  very 
  injurious 
  in 
  vineyards 
  in 
  the
