  The 
  Green 
  

   Flata, 
  Chlorochroa 
  

   conica. 
  

  

  The 
  green 
  Flata 
  is 
  clear 
  yellowish-green 
  throughout, 
  about 
  three- 
  

   eighths 
  of 
  an 
  inch 
  long, 
  and 
  the 
  wings 
  about 
  one-fifth 
  of 
  an 
  inch 
  broad. 
  

   The 
  head 
  is 
  pointed 
  in 
  front 
  between 
  the 
  eyes. 
  The 
  

   mealy 
  Flata 
  is 
  smaller 
  than 
  the 
  above, 
  about 
  one-fourth 
  

   of 
  an 
  inch 
  in 
  length 
  and 
  one-eighth 
  of 
  an 
  inch 
  across 
  

   the 
  wings. 
  Its 
  color 
  is 
  at 
  first 
  pale 
  bluish-green, 
  some- 
  

   times 
  darkening 
  to 
  a 
  slate-color 
  or 
  sooty 
  brown, 
  dusted 
  

   over 
  with 
  a 
  whitish 
  coat. 
  The 
  head 
  is 
  short 
  and 
  cut 
  

   squarely 
  off 
  across 
  the 
  front 
  between 
  the 
  eyes. 
  

  

  Both 
  the 
  above 
  species 
  have 
  been 
  found 
  on 
  sugar 
  beets 
  and 
  on 
  a 
  

   variety 
  of 
  other 
  plants, 
  sometimes 
  in 
  number 
  sufficient 
  to 
  do 
  injury, 
  

   although 
  in 
  general 
  they 
  are 
  not 
  very 
  common 
  insects. 
  

   Many 
  adults 
  of 
  both 
  were 
  seen 
  by 
  us 
  in 
  July 
  on 
  sugar 
  

   beets 
  with 
  beaks 
  inserted 
  in 
  the 
  leaves. 
  They 
  were 
  

   most 
  abundant 
  near 
  a 
  hedge 
  of 
  Osage 
  orange, 
  one 
  of 
  

   their 
  favorite 
  food 
  plants, 
  on 
  which 
  they 
  had 
  very 
  likely 
  

   bred. 
  The 
  eggs 
  of 
  the 
  mealy 
  Flata 
  are 
  laid 
  in 
  the 
  bark 
  

   of 
  twigs 
  within 
  a 
  lengthwise 
  slit 
  with 
  raised 
  edges, 
  and 
  

   are 
  placed 
  end 
  to 
  end 
  in 
  a 
  continuous 
  row 
  an 
  inch 
  or 
  

   more 
  in 
  length. 
  Those 
  believed 
  to 
  belong 
  to 
  the 
  green 
  

   Flata, 
  on 
  the 
  other 
  hand, 
  are 
  placed 
  in 
  a 
  series 
  of 
  short 
  

   slits, 
  placed 
  nearly 
  end 
  to 
  end, 
  within 
  each 
  of 
  which 
  

   is 
  an 
  egg 
  which 
  has 
  been 
  pushed 
  sidewise 
  under 
  the 
  

   bark, 
  causing 
  a 
  noticeable 
  elevation 
  of 
  the 
  bark 
  over 
  

   the 
  eggs. 
  

  

  FiS

  mealy 
  Flata 
  is 
  recorded 
  by 
  various 
  authors 
  as

  and 
  various 
  other 
  weeds. 
  

   Miss 
  Murtfeldt 
  * 
  found 
  it 
  on 
  a 
  large 
  variety 
  of 
  plants, 
  but 
  especially 
  on 
  

   dahlias, 
  which 
  were 
  injured 
  beyond 
  recovery. 
  We 
  have 
  bred 
  it 
  from 
  

   nymphs 
  on 
  apple, 
  elm, 
  box-elder, 
  and 
  observed 
  it 
  in 
  numbers 
  on 
  black- 
  

   berry, 
  sugar 
  beet, 
  and 
  Osage 
  orange, 
  on 
  the 
  first 
  of 
  which 
  it 
  was 
  seen 
  

   actually 
  to 
  feed. 
  Riley 
  found 
  the 
  eggs 
  in 
  sassafras 
  twigs. 
  The 
  green 
  

   Flata 
  probably 
  has 
  a 
  similar 
  list 
  of 
  food 
  plants. 
  Miss 
  Murtfeldt 
  ob- 
  

   served 
  it 
  on 
  Osage 
  orange 
  and 
  lilac. 
  It 
  was 
  found 
  by 
  an 
  assistant 
  of 
  

   this 
  office, 
  Mr. 
  C. 
  C. 
  Adams, 
  breeding 
  abundantly 
  (June 
  30th) 
  on 
  the 
  

   stalks 
  of 
  corn 
  in 
  a 
  corner 
  of 
  a 
  field, 
  and 
  was 
  later 
  found 
  in 
  numbers 
  on 
  

   ragweed, 
  catnip, 
  milkweed, 
  and 
  the 
  Osage 
  orange 
  in 
  the 
  same 
  vicinity. 
  

   Probably 
  these 
  species 
  hibernate 
  in 
  the 
  egg, 
  which, 
  according 
  to 
  

   Riley, 
  hatches 
  about 
  the 
  middle 
  of 
  May. 
  Nymphs 
  of 
  the 
  mealy 
  Flata
