﻿THE

  ateiiess 
  of 
  their 
  popular 
  name, 
  for 
  in 
  their 
  earlier 
  periods, 
  by 
  eating 
  nu- 
  

   merous 
  irregular 
  holes 
  through 
  the 
  leaves, 
  they 
  reduce 
  them 
  to 
  a 
  skele- 
  

   tonized 
  condition 
  and 
  interrupt 
  the 
  flow 
  of 
  sap, 
  and 
  the 
  leaf 
  becoming 
  

   withered 
  and 
  brown 
  before 
  it 
  is 
  wholly 
  eaten 
  gives 
  the 
  tree 
  the 
  appear- 
  

   ance 
  of 
  having 
  been 
  scorched 
  with 
  fire. 
  Harris 
  says 
  it 
  reduces 
  the 
  foli- 
  

   age 
  of 
  our 
  fruit 
  trees 
  and 
  of 
  our 
  noble 
  elms 
  to 
  withered 
  and 
  lifeless 
  

   shreds, 
  and 
  causes 
  whole 
  orchards 
  to 
  look 
  as 
  if 
  they 
  had 
  been 
  suddenly 
  

   scorched 
  with 
  fire. 
  Eathvon 
  says 
  that 
  when 
  the 
  Canker 
  Worms 
  have 
  

   overrun 
  an 
  apple 
  tree, 
  the 
  leaves 
  which 
  they 
  have 
  not 
  devoured 
  will 
  

   present 
  the 
  dry 
  and 
  browned 
  appearance 
  of 
  a 
  rose-bush 
  that 
  has 
  been 
  

   devastated 
  by 
  rose- 
  slugs. 
  

  

  Mr. 
  John 
  Tinker, 
  of 
  Clinton, 
  Eock 
  County, 
  Wisconsin, 
  states^* 
  that 
  

   apple 
  trees 
  will 
  perish 
  after 
  having 
  been 
  defoliated 
  three 
  years 
  in 
  suc- 
  

   cession, 
  and 
  Dr. 
  LeBaron 
  says 
  that 
  in 
  the 
  fifth 
  year 
  in 
  which 
  the 
  Canker 
  

   Worms 
  had 
  appeared 
  in 
  the 
  orchard 
  in 
  which 
  he 
  made 
  his 
  observations, 
  

   some 
  of 
  the 
  trees 
  were 
  dead 
  and 
  others 
  were 
  in 
  a 
  dying 
  condition. 
  

  

  We 
  know 
  of 
  few 
  more 
  discouraging 
  sights 
  than 
  an 
  orchard 
  which 
  has 
  

   been 
  badly 
  injured 
  by 
  these 
  pests, 
  presenting 
  as 
  it 
  does, 
  in 
  midsummer, 
  

   the 
  seared 
  and 
  blasted 
  aspect 
  that 
  follows 
  fire. 
  

  

  Where 
  they 
  have 
  become 
  established 
  and 
  are 
  neglected, 
  their 
  rava- 
  

   ges 
  soon 
  become 
  very 
  great, 
  but 
  our 
  own 
  experience, 
  in 
  Missouri 
  and 
  

   Illinois, 
  would 
  indicate 
  that 
  old 
  orchards 
  sufler 
  most. 
  

  

  THE 
  FALL 
  CAHKEE 
  WOEM. 
  

  

  {Anisopteryx 
  pometaria 
  Harr.) 
  

  

  RANGE 
  OF 
  THE 
  SPECIES. 
  

  

  There 
  is 
  no 
  evidence 
  that 
  pometaria 
  occurs 
  at 
  all 
  anywhere 
  in 
  the 
  

   Mississippi 
  Valley, 
  since 
  an 
  examination 
  of 
  the 
  specimens 
  of 
  Canker 
  

   Worms 
  in 
  Dr. 
  LeBaron's 
  cabinet, 
  and 
  in 
  our 
  own, 
  proves 
  them 
  all 
  to 
  

   be 
  the 
  true 
  or 
  Spring 
  species. 
  Indeed, 
  until 
  we 
  received 
  specimens 
  of 
  

   pometaria 
  from 
  Mr. 
  H. 
  K. 
  Morrison 
  and 
  Mr. 
  Mann, 
  we 
  had 
  never 
  seen 
  

   the 
  species, 
  the 
  male 
  specimens 
  which 
  we 
  mistook 
  for 
  it 
  in 
  former 
  years 
  

   being 
  in 
  reality 
  specimens 
  of 
  vernata, 
  which 
  aj^proach 
  it 
  in 
  the 
  markings 
  

   of 
  the 
  front 
  wings. 
  

  

  As 
  Canker 
  Worms 
  are 
  not 
  very 
  injurious 
  in 
  Canada, 
  and 
  occur, 
  when 
  

   at 
  all, 
  generally 
  in 
  October 
  and 
  November, 
  our 
  Canadian 
  neighbors 
  are 
  

   doubtless 
  afflicted 
  with 
  the 
  Fall 
  species. 
  

  

  The 
  Fall 
  species 
  may 
  be 
  said 
  to 
  range 
  from 
  the 
  eastern 
  shore 
  and 
  the 
  

   northern 
  boundary 
  of 
  Massachusetts 
  to 
  the 
  western 
  extremity 
  of 
  the 
  

   Canadian 
  peninsula, 
  between 
  Lakes 
  Ontario 
  and 
  Erie 
  and 
  the 
  southern 
  

   shore 
  of 
  Connecticut 
  and 
  Ehode 
  Island. 
  Probably 
  its 
  range 
  is 
  wider, 
  

   but 
  we 
  only 
  have 
  reliable 
  reports 
  from 
  about 
  Salem, 
  Boston, 
  and 
  Cam- 
  

   bridge, 
  Mass., 
  and 
  New 
  Haven, 
  Conn.
