  , 
  No 
  eggs 
  were 
  apparently 
  deposited 
  by 
  them, 
  and 
  in 
  the 
  course 
  

   of 
  about 
  ten 
  days 
  the 
  adults 
  were 
  all 
  dead. 
  As 
  they 
  had 
  no 
  proper 
  food, 
  

   this 
  probably 
  hastened 
  their 
  death 
  and 
  might 
  also 
  account 
  for 
  the 
  non- 
  

   production 
  of 
  eggs. 
  

  

  Earlier 
  History 
  and 
  Nature 
  of 
  its 
  Injuries. 
  

  

  The 
  operations 
  of 
  the 
  insect 
  first 
  came 
  under 
  the 
  notice 
  of 
  Dr. 
  Fitch 
  in 
  

   1854, 
  and 
  at 
  tliat 
  time 
  it 
  seemed 
  to 
  him 
  more 
  destructive 
  than 
  any 
  other 
  

   grapevine-feeding 
  species 
  whose 
  life-history 
  had 
  hitherto 
  been 
  given. 
  It 
  

   was 
  reported 
  in 
  1869 
  as 
  very 
  common 
  in 
  Missouri 
  by 
  Prof. 
  Riley, 
  and 
  

   the 
  following 
  year 
  it 
  was 
  more 
  injurious 
  than 
  usual 
  in 
  that 
  section. 
  The 
  

   same 
  year 
  it 
  was 
  very 
  troublesome 
  in 
  Canada, 
  according 
  to 
  Mr. 
  Saunders. 
  

  

  The 
  principal 
  injury 
  by 
  this 
  insect 
  is 
  the 
  destruction 
  of 
  the 
  unfolding 
  

   leaves 
  in 
  the 
  early 
  spring, 
  and 
  if 
  unmolested 
  the 
  young 
  larvae 
  will 
  later 
  

   devour 
  the 
  forming 
  blossoms. 
  

  

  Distribution. 
  

  

  The 
  gartered 
  plume 
  has 
  a 
  wide 
  distribution 
  throughout 
  Canada, 
  the 
  

   Eastern 
  United 
  States, 
  and 
  westward 
  at 
  least 
  as 
  far 
  as 
  Missouri. 
  It 
  is 
  

   also 
  known 
  to 
  occur 
  in 
  Nebraska, 
  and 
  California, 
  and 
  it 
  will 
  probably 
  be 
  

   found 
  in 
  all 
  of 
  the 
  Northern 
  and 
  Middle 
  States 
  of 
  the 
  Union. 
  

  

  Parasites. 
  

   Several 
  parasites 
  have 
  been 
  reared 
  from 
  this 
  insect 
  by 
  Dr. 
  George 
  

   Dimmock, 
  who 
  simply 
  records 
  the 
  fact 
  without 
  giving 
  the 
  names. 
  None 
  

   were 
  obtained 
  by 
  me 
  the 
  past 
  season, 
  and 
  there 
  is 
  no 
  record 
  at 
  hand 
  of 
  

   rearings 
  by 
  others. 
  From 
  this, 
  it 
  may 
  be 
  inferred, 
  that 
  the 
  parasites 
  of 
  

   this 
  insect 
  are 
  not 
  abundant. 
  

  

  Remedies. 
  

  

  The 
  presence 
  of 
  the 
  larvae, 
  is 
  readily 
  indicated 
  b)'^ 
  the 
  webbing 
  together 
  

   of 
  the 
  terminal 
  leaves. 
  The 
  caterpillars 
  are 
  so 
  sheltered 
  within 
  the 
  

   inclosing 
  leaves, 
  that 
  arsenical 
  spraying 
  would 
  be 
  of 
  little 
  value 
  against 
  

   them. 
  The 
  most 
  practicable 
  method 
  of 
  keeping 
  the 
  insect 
  in 
  check, 
  

   appears 
  to 
  be 
  tjie 
  simple 
  one 
  of 
  going 
  over 
  the 
  vines 
  a 
  few 
  times 
  in 
  the 
  

   early 
  spring 
  and 
  crushing 
  the 
  concealed 
  caterpillars 
  by 
  hand 
  within 
  their 
  

   nests, 
  which 
  are 
  easily 
  detected.
