  OF 
  THE

  grown 
  caterpillars 
  is 
  becoming 
  apparent. 
  The 
  general 
  color 
  of 
  the 
  body 
  

   is 
  yellowish-green 
  with 
  three, 
  more 
  or 
  less 
  well 
  defined, 
  rose-brown 
  lines 
  

   on 
  each 
  side 
  of 
  the 
  body, 
  — 
  the 
  lower 
  line 
  being 
  the 
  broadest 
  and 
  the 
  most 
  

   conspicuous. 
  In 
  this 
  stage 
  the 
  minute 
  black 
  hairy 
  tubercles 
  of 
  the 
  body 
  

   may 
  be 
  seen. 
  . 
  The 
  caterpillar 
  still 
  loops 
  as 
  it 
  walks 
  and 
  spins 
  a 
  thread 
  

   as 
  it 
  drops 
  from 
  a 
  leaf 
  when 
  disturbed, 
  as 
  in 
  the 
  first 
  stage. 
  After 
  the 
  

   second 
  molt 
  the 
  striping 
  is 
  more 
  pronounced, 
  though 
  the 
  general 
  color 
  is 
  

   the 
  same. 
  The 
  habit 
  of 
  looping 
  when 
  walking 
  and 
  of 
  spinning 
  a 
  thread 
  

   when 
  it 
  drops 
  is 
  lost 
  : 
  instead 
  of 
  the 
  latter 
  it 
  curls 
  itself 
  up 
  as 
  it 
  falls 
  to 
  the 
  

   ground. 
  After 
  the 
  third 
  molt 
  the 
  caterpillars 
  become 
  a 
  dull, 
  dark 
  green 
  

   color 
  and 
  the 
  head 
  is 
  mottled 
  with 
  dark 
  brown. 
  The 
  striping 
  is 
  nearly 
  

   that 
  of 
  the 
  full-grown 
  caterpillar. 
  In 
  the 
  next 
  two 
  molts 
  there 
  is 
  but 
  

   little 
  change 
  in 
  its 
  markings 
  and 
  other 
  features. 
  

  

  The 
  fidl-growii 
  caterpillai'.—WhQiv 
  full-grown 
  or 
  nearly 
  full-grown, 
  

   there 
  is 
  quite 
  a 
  range 
  of 
  coloring 
  to 
  be 
  seen 
  among 
  a 
  large 
  number. 
  

   Their 
  general 
  appearance 
  is 
  such 
  that 
  once 
  seen 
  they 
  are 
  easily 
  recog- 
  

   nized. 
  The 
  larger 
  ones 
  are 
  about 
  one 
  inch 
  and 
  one-half 
  (38 
  mm.) 
  long, 
  

   but 
  associated 
  with 
  them 
  are 
  many 
  smaller 
  individuals, 
  some 
  of 
  which 
  

   are 
  only 
  about 
  half 
  the 
  length 
  of 
  the 
  largest. 
  This 
  range 
  in 
  size 
  may 
  be 
  

   seen 
  at 
  the 
  time 
  when 
  their 
  ravages 
  attract 
  attention. 
  They 
  may 
  be 
  re- 
  

   cognized 
  in 
  their 
  latter 
  stages 
  by 
  the 
  median 
  white 
  line 
  beginning 
  at 
  the 
  

   head 
  and 
  extending 
  a 
  variable 
  distance 
  along 
  the 
  back. 
  — 
  in 
  some 
  of 
  the 
  

   lighter 
  and 
  younger 
  ones 
  it 
  may 
  be 
  traced 
  the 
  length 
  of 
  the 
  body. 
  On 
  

   either 
  side 
  of 
  the 
  median 
  white 
  line, 
  there 
  is 
  a 
  broad 
  brown 
  stripe 
  more 
  

   or 
  less 
  distinct 
  (in 
  lighter 
  individuals 
  there 
  may 
  be 
  a 
  white 
  mottling 
  along 
  

   this 
  stripe), 
  bordered 
  laterally 
  by 
  a 
  narrow 
  one 
  of 
  darker 
  brown. 
  Next 
  

   is 
  a 
  white 
  hue 
  similar 
  to 
  the 
  median 
  one 
  but 
  more 
  constant, 
  and 
  be- 
  

   . 
  tween 
  it 
  and 
  the 
  next 
  white 
  line 
  there 
  is 
  a 
  stripe 
  of 
  variable 
  brown, 
  some- 
  

   times 
  mottled 
  with 
  white 
  ; 
  it 
  is 
  usually 
  lighter 
  than 
  the 
  stripe 
  on 
  either 
  

   side 
  of 
  the 
  median 
  white 
  line. 
  Next 
  comes 
  the 
  stigmatal 
  stripe 
  which 
  

   in 
  well-marked 
  individuals 
  is 
  the 
  most 
  striking, 
  it 
  being 
  as 
  dark 
  as 
  any, 
  

   and 
  below 
  it 
  is 
  the 
  white 
  substigmatal 
  stripe 
  ; 
  these 
  two 
  are 
  somewhat 
  

   variable 
  in 
  color 
  in 
  different 
  caterpillars. 
  The 
  ventral 
  surface 
  is 
  a 
  vari- 
  

   able 
  yellowish-green 
  : 
  the 
  abdominal 
  legs 
  are 
  brown 
  at 
  the 
  base. 
  The 
  

   light 
  and 
  dark 
  varieties 
  of 
  the 
  caterpillars 
  are 
  represented 
  in 
  the 
  two 
  

   lower 
  figures 
  of 
  Plate 
  III. 
  

  

  The 
  pupa 
  The 
  mahogany-brown 
  pupa 
  is 
  about 
  three-fourths 
  of 
  an 
  

  

  inch 
  (18 
  to 
  20 
  mm.) 
  long. 
  It 
  is 
  rather 
  stout 
  and 
  on 
  the 
  anal 
  extremity 
  

   there 
  is 
  a 
  pair 
  of 
  slightly 
  converging 
  spines, 
  and 
  on 
  each 
  side 
  of 
  these, 
  

   two 
  fine 
  curled 
  hooks. 
  The 
  spiracles 
  are 
  nearly 
  black.
