  During

   this 
  month 
  I 
  have 
  frequently 
  seen 
  the 
  moths 
  at 
  twilight 
  in 
  Amherst, 
  

   Mass., 
  flying 
  about 
  the- 
  flowers 
  of 
  the 
  petunia, 
  probing 
  their 
  deep 
  

   tubular 
  cerollas 
  with 
  their 
  long 
  tongue. 
  Our 
  figure, 
  (47,)

  from

  will 
  sufiBciently 
  indicate 
  the 
  size 
  and 
  transformations 
  of 
  this 
  ^ 
  

   common 
  moth, 
  the 
  caterpillar 
  of 
  which, 
  in 
  the 
  S^orthern 
  States, 
  often 
  

   passes 
  under 
  the 
  name 
  of 
  the 
  tomato 
  or 
  potato 
  worm. 
  

  

  The 
  caterpillar 
  is 
  rather 
  dark 
  green, 
  with 
  seven 
  oblique 
  greenish- 
  i 
  

   yellow 
  stripes 
  on 
  the 
  side 
  of 
  the 
  body. 
  The 
  chrysalis 
  may 
  be 
  known 
  

   by 
  the 
  large, 
  conspicuous 
  tongue-case 
  which 
  projects 
  from 
  the 
  body 
  like 
  

   the 
  handle 
  of 
  a 
  pitcher.

  In 
  the 
  Macrosila

  is 
  no 
  white 
  spot 
  at 
  the 
  base 
  of 
  the 
  , 
  

   fore 
  wings, 
  and 
  on 
  the 
  hind 
  wings 
  are 
  two 
  distinct 
  angulated 
  bands.

   The 
  Carolina 
  moth

  a

  spot

  of 
  the 
  '' 
  

   fore 
  wings, 
  while 
  the 
  central 
  band 
  of 
  the 
  hind 
  wings 
  is 
  indistinct. 
  The 
  

   caterpillar 
  feeds 
  on 
  the 
  tobacco 
  and 
  the 
  tomato. 
  It 
  is 
  dark 
  green, 
  with 
  

   lateral, 
  oblique, 
  white 
  bands, 
  edged 
  above

  My 
  attention 
  has 
  been 
  i 
  

   drawn 
  for 
  two 
  years 
  past, 
  while 
  spending 
  a 
  few 
  weeks 
  in 
  September 
  at 
  / 
  

   the 
  Agricultural 
  College 
  in 
  Amherst, 
  to 
  the 
  ravages 
  of 
  this 
  pest, 
  by 
  i 
  

   Professor 
  Maynard. 
  In 
  the 
  autumn 
  of 
  1875, 
  we 
  found 
  it

  abundance

   on 
  the 
  leaves 
  of 
  several 
  varieties 
  in 
  the 
  vineyard 
  on 
  the 
  college 
  farm, 
  i 
  

   while 
  this 
  year, 
  in 
  company 
  with 
  Professor 
  Maynard, 
  I 
  examined 
  the 
  : 
  

   roots 
  and 
  found 
  the 
  following 
  varieties 
  more 
  or 
  less 
  infested 
  by 
  the 
  root- 
  ^ 
  

   variety 
  of 
  this 
  plant-louse: 
  Clinton, 
  Agawam, 
  Concord, 
  lona, 
  Delaware, 
  

   Adirondack, 
  Israella, 
  Isabella, 
  Wilder, 
  and 
  the 
  native 
  grape 
  under 
  , 
  

   cultivation 
  ; 
  the 
  Clinton 
  was 
  affected 
  more 
  than 
  the 
  others, 
  and 
  the 
  f 
  

   Concord 
  much 
  so 
  when 
  growing 
  in 
  a 
  slightly 
  damp, 
  ill-drained 
  and 
  par- 
  i 
  

   tially 
  shady 
  place.

  I 
  am 
  not 
  aware 
  that 
  this 
  formidable 
  pest, 
  which 
  has 
  occasioned 
  such 
  i 
  

   consternation 
  in 
  Europe, 
  has 
  been 
  detected 
  before 
  in 
  New 
  England,
