﻿REPORT 
  OF 
  THE 
  STATE 
  ENTOMOLOGIST

  to 
  the 
  growing 
  twigs 
  arrested 
  their 
  growth, 
  and 
  caused 
  the 
  young 
  trees 
  

   to 
  throw 
  out 
  additional 
  side 
  shoots. 
  In 
  many 
  instances 
  these 
  shoots 
  

   would 
  also 
  be 
  attacked 
  and 
  the 
  tree, 
  as 
  the 
  result, 
  would 
  develop 
  a 
  thick 
  

   head 
  of 
  stubby 
  branches. 
  Many 
  of 
  these 
  stunted 
  and 
  deformed 
  trees 
  

   were 
  cut 
  back 
  and 
  allowed 
  to 
  start 
  again 
  before 
  they 
  were 
  sold. 
  

  

  At 
  the 
  time 
  of 
  my 
  visit 
  (August), 
  it 
  was 
  too 
  late 
  to 
  identify 
  positively 
  

   the 
  author 
  of 
  the 
  injury, 
  as 
  most 
  of 
  the 
  damage 
  had 
  been 
  inflicted 
  early 
  

   in 
  the 
  spring. 
  An 
  examination, 
  however, 
  showed 
  the 
  presence 
  of 
  the 
  

   tarnished 
  plant-bug, 
  on 
  the 
  trees. 
  A 
  grower 
  informed 
  me 
  that 
  Prof. 
  

   Slingerland, 
  of 
  the 
  Cornell 
  agricultural 
  experiment 
  station, 
  had 
  been 
  

   studying 
  the 
  work 
  of 
  the 
  insect 
  a 
  year 
  or 
  two 
  before. 
  On 
  communi- 
  

   cating 
  with 
  him, 
  my 
  suspicion 
  as 
  to 
  the 
  cause 
  of 
  the 
  injury 
  was 
  confirmed, 
  

   he 
  having 
  found 
  their 
  eggs 
  in 
  blighted 
  tips 
  and 
  watched 
  their 
  oviposition 
  

   in 
  breeding 
  cages. 
  

  

  Description. 
  The 
  following 
  description 
  of 
  the 
  immature 
  stages 
  of 
  

   this 
  insect 
  is 
  compiled 
  from 
  the 
  notices 
  of 
  it 
  by 
  Prof. 
  Forbes. 
  

  

  The 
  egg. 
  The 
  smooth, 
  pale 
  watery-yellow 
  egg 
  of 
  this 
  species 
  is 
  

   slender, 
  cylindric, 
  shghtly 
  curved, 
  round 
  at 
  one 
  end, 
  truncate 
  and 
  com- 
  

   pressed 
  at 
  the 
  other, 
  .92 
  mm 
  long 
  and 
  .25 
  mm 
  wide 
  at 
  its 
  greater 
  diameter. 
  

  

  The 
  single 
  example 
  from 
  which 
  the 
  above 
  description 
  was 
  drawn, 
  was 
  

   loosely 
  placed 
  among 
  the 
  hairs 
  on 
  the 
  petiole 
  of 
  a 
  dead 
  leaf. 
  According 
  

   to 
  Prof. 
  Slingerland's 
  observations, 
  the 
  eggs 
  were 
  evidently 
  deposited 
  

   within 
  the 
  young 
  stems 
  of 
  peach 
  trees. 
  

  

  The 
  first 
  stage. 
  The 
  recently 
  emerged 
  bug 
  is 
  a 
  pale 
  green 
  or 
  sulfur- 
  

   yellow 
  color 
  with 
  a 
  median 
  orange 
  spot 
  on 
  the 
  third 
  abdominal 
  segment, 
  

   and 
  about 
  g-o 
  inch 
  long. 
  The 
  antennae 
  are 
  nearly 
  as 
  long 
  as 
  the 
  body, 
  

   the 
  beak 
  extends 
  to 
  the 
  last 
  abdominal 
  segment. 
  Head 
  sHghtly 
  darker 
  

   before 
  the 
  eyes, 
  legs 
  long, 
  white, 
  with 
  an 
  orange 
  ring 
  at 
  the 
  upper 
  

   end 
  of 
  the 
  tibiae. 
  In 
  the 
  latter 
  part 
  of 
  this 
  stage 
  the 
  antennae, 
  tarsi 
  and 
  

   apical 
  segment 
  of 
  the 
  beak 
  become 
  dusky, 
  and 
  a 
  transverse 
  black 
  mark 
  

   is 
  seen 
  just 
  behind 
  the 
  orange 
  spot 
  on 
  the 
  abdomen. 
  The 
  tiny 
  insect 
  is 
  

   sparsely 
  covered 
  with 
  short 
  black 
  hairs. 
  

  

  The 
  second 
  stage. 
  After 
  the 
  first 
  molt 
  it 
  is 
  -^ 
  inch 
  long, 
  the 
  abdomen 
  

   is 
  broader 
  than 
  the 
  thorax, 
  a 
  circular 
  black 
  spot 
  occurs 
  on 
  each 
  

   side 
  of 
  the 
  middle 
  of 
  the 
  first 
  and 
  second 
  thoracic 
  segments, 
  and 
  a 
  

   median 
  black 
  quadrate 
  spot 
  on 
  the 
  suture 
  between 
  the 
  third 
  and 
  fourth 
  

   abdominal 
  segments. 
  The 
  legs 
  are 
  much 
  as 
  before, 
  except 
  that 
  the 
  tibial 
  

   rings 
  are 
  more 
  brightly 
  colored 
  and 
  there 
  are 
  traces 
  of 
  a 
  second 
  reddish 
  

   tibial 
  ring 
  and 
  of 
  two 
  femoral 
  rings. 
  The 
  antennae 
  are 
  relatively 
  shorter 
  

   and 
  darker, 
  being 
  reddish 
  dusky 
  with 
  pale 
  articulations, 
  except 
  that 
  the 
  

   second 
  segment 
  has 
  a 
  paler 
  shade 
  in 
  the 
  middle, 
  and 
  the 
  basal 
  one 
  is 
  

   nearly 
  white. 
  

  

  The 
  third 
  stage. 
  The 
  greatest 
  change 
  after 
  the 
  second 
  molt 
  is 
  in 
  size, 
  

   the 
  insect 
  being 
  -^^ 
  or 
  -^^ 
  inch 
  long, 
  the 
  wing 
  pads 
  are 
  just 
  begin- 
  

   ning 
  to 
  appear, 
  and 
  there 
  is 
  a 
  higher 
  coloration. 
  ' 
  In 
  the 
  more 
  strongly 
  

   marked 
  specimens, 
  the 
  head, 
  abdomen, 
  legs 
  and 
  antennae, 
  are 
  more 
  or 
  

   less 
  deeply 
  suffused 
  with 
  crimson, 
  the 
  head 
  having 
  a 
  median 
  longitudinal
