  The 
  outbreak 
  of 
  this 
  insect 
  in 
  certain 
  parts 
  of 
  New 
  York 
  state 
  lapt 
  

   summer 
  was 
  unusual 
  though 
  not 
  unprecedented. 
  My 
  attention 
  was 
  

   first 
  called 
  on 
  June 
  13 
  by 
  J. 
  F. 
  Rose, 
  voluntary 
  observer 
  for 
  Genesee 
  

   county, 
  to 
  the 
  serious 
  injuries 
  by 
  this 
  insect. 
  Specimens 
  were 
  sent 
  at 
  

   this 
  time 
  and 
  also 
  about 
  a 
  week 
  later. 
  The 
  condition 
  of 
  the 
  foliage 
  and 
  

   young 
  fruit 
  then 
  is 
  well 
  shown

  Mr 
  Rose 
  stated 
  that 
  

   the 
  crop 
  in 
  this 
  orchard 
  of 
  300 
  trees 
  was 
  a 
  complete 
  failure, 
  though 
  the 
  

   trees 
  had 
  bloomed 
  well. 
  He 
  found 
  palmer 
  worms 
  in 
  greater 
  or 
  less 
  

   numbers 
  in 
  every 
  orchard 
  he 
  visited 
  but 
  one, 
  though 
  as 
  a 
  rule 
  the 
  

   trees 
  were 
  not 
  so 
  badly 
  affected 
  as 
  in 
  the 
  first. 
  This 
  pest 
  was 
  pres- 
  

   ent 
  in 
  considerable 
  numbers 
  in 
  many 
  of 
  the 
  apple 
  orchards 
  of 
  central 
  and 
  

   western 
  New 
  York 
  and 
  was 
  the 
  cause 
  of 
  complaints 
  in 
  the 
  vicinity 
  of 
  

   Albany, 
  where 
  some 
  trees 
  were 
  seriously 
  injured. 
  

  

  Early 
  history. 
  This 
  insect 
  received 
  the 
  popular 
  name 
  of 
  palmer 
  

   worm 
  in 
  1 
  791, 
  at 
  which 
  time 
  it 
  was 
  abundant 
  and 
  destructive 
  in 
  New 
  

   England 
  orchards 
  and 
  forests, 
  particularly 
  in 
  Cumberland 
  county 
  (Me.). 
  

   Its 
  ravages 
  did 
  not 
  attract 
  notice 
  again 
  for 
  62 
  years, 
  when 
  it 
  was 
  exceed- 
  

   ingly 
  numerous 
  in 
  all 
  of 
  the 
  New 
  England 
  states 
  and 
  in 
  eastern 
  New 
  

   York, 
  at 
  which 
  time 
  it 
  came 
  under 
  the 
  notice 
  of 
  Dr 
  Harris, 
  its 
  describer, 
  

   and 
  Dr 
  Asa 
  Fitch, 
  entomologist 
  to 
  the
