﻿REPORT 
  OF 
  THE 
  STATE 
  ENTOMOLOGIST 
  185 
  

  

  25th, 
  when 
  the 
  earliest 
  had 
  taken 
  the 
  position 
  for 
  the 
  3d 
  molt, 
  having 
  a 
  

   length 
  of 
  0.35 
  in. 
  The 
  preparation 
  for 
  the 
  molt 
  is 
  made 
  by 
  leaving 
  the 
  

   plant 
  and 
  selecting 
  a 
  place 
  on 
  the 
  top 
  of 
  the 
  jar 
  containing 
  the 
  larvae, 
  

   where 
  each 
  spins 
  a 
  web 
  of 
  three 
  times 
  the 
  area 
  of 
  its 
  body, 
  in 
  which 
  it 
  

   may 
  securely 
  fasten 
  its 
  prolegs 
  — 
  such 
  attachment 
  being 
  apparently 
  

   necessary 
  for 
  its 
  successful 
  escape 
  from 
  the 
  cast 
  skin. 
  

  

  October 
  27th. 
  Third 
  molt 
  commenced. 
  Ended 
  on 
  the 
  30th. 
  

   Color 
  dull 
  red. 
  The 
  brown 
  has 
  become 
  black 
  and 
  its 
  area 
  is 
  extending, 
  

   as 
  segment 
  3 
  is 
  also 
  black, 
  in 
  addition 
  to 
  4, 
  5, 
  8 
  to 
  10. 
  On 
  the 
  ter- 
  

   minal 
  segment 
  (12) 
  the 
  two 
  subdorsal 
  tubercles 
  are 
  shining-black. 
  On 
  

   the 
  evening 
  of 
  the 
  31st, 
  the 
  first 
  two 
  took 
  position 
  for 
  the 
  4th 
  molt 
  — 
  

   length 
  0.45 
  in. 
  With 
  very 
  few 
  exceptions 
  (the 
  result 
  perhaps 
  of 
  disturb- 
  

   ance) 
  the 
  larvas 
  after 
  their 
  molting 
  reverse 
  their 
  position 
  and 
  entirely 
  

   consume 
  their 
  exuvia. 
  

  

  November 
  ist. 
  Fourth 
  molt 
  commenced 
  — 
  i 
  molted; 
  on 
  2d, 
  10 
  

   molted; 
  on 
  3d 
  all 
  of 
  previous 
  molt 
  had 
  ceased 
  feeding, 
  and 
  were 
  in 
  

   position 
  on 
  the 
  lid 
  and 
  sides 
  of 
  the 
  glass 
  jar, 
  for 
  their 
  approaching 
  molt 
  — 
  

   a 
  few 
  only 
  remained 
  upon 
  the 
  leaves. 
  The 
  molting 
  was 
  completed 
  on 
  

   the 
  mornin-g 
  of 
  the 
  5th. 
  Portions 
  of 
  about 
  20 
  per 
  cent, 
  of 
  the 
  exuviae 
  

   were 
  uneaten. 
  In 
  several 
  instances 
  the 
  larvae 
  were 
  seen 
  to 
  commence 
  

   feeding 
  upon 
  the 
  spines, 
  biting 
  them 
  off 
  in 
  small 
  pieces, 
  before 
  attacking 
  

   the 
  skin. 
  The 
  withdrawal 
  from 
  the 
  old 
  skin 
  occupied 
  about 
  a 
  minute. 
  

   The 
  spines, 
  first 
  appressed 
  to 
  the 
  body 
  beneath 
  the 
  old 
  skin, 
  appear 
  as 
  

   wet 
  places, 
  but 
  at 
  once 
  begin 
  to 
  expand 
  and 
  dry. 
  Their 
  final 
  adjust- 
  

   ment 
  is 
  apparently 
  hastened 
  by 
  the 
  contortions 
  in 
  which 
  the 
  larva 
  throws 
  

   Itself, 
  by 
  resting 
  on 
  three 
  pairs 
  of 
  prolegs, 
  and 
  with 
  the 
  two 
  extremities 
  

   raised 
  and 
  curved 
  over 
  the 
  back, 
  almost 
  touching 
  one 
  another, 
  

   frequently 
  twisting, 
  at 
  short 
  intervals, 
  from 
  side 
  to 
  side. 
  In 
  about 
  an 
  

   hour 
  after 
  emerging, 
  the 
  meal 
  upon 
  the 
  exuviae 
  is 
  commenced. 
  

  

  With 
  its 
  longer 
  spines, 
  the 
  caterpillar 
  is 
  now 
  nearly 
  twice 
  as 
  broad 
  as 
  

   before, 
  but 
  not 
  much 
  increased 
  in 
  length, 
  averaging 
  but 
  0.5 
  in. 
  The 
  cen- 
  

   tral 
  and 
  terminal 
  segments 
  are 
  still 
  red, 
  but 
  diminished 
  in 
  extent 
  and 
  less 
  

   conspicuous 
  than 
  before 
  — 
  the 
  red 
  of 
  the 
  extremities 
  being 
  nearly 
  con- 
  

   cealed 
  beneath 
  the 
  long 
  black 
  spines 
  radiating 
  from 
  the 
  tubercles. 
  The 
  

   legs, 
  prolegs, 
  and 
  ventral 
  surface 
  aie 
  red, 
  the 
  plantae 
  of 
  the 
  prolegs 
  being 
  

   quite 
  pale 
  — 
  almost 
  a 
  flesh 
  color. 
  The 
  spines 
  on 
  segments 
  6 
  and 
  7 
  are 
  

   dusky, 
  interspersed 
  with 
  a 
  few 
  black 
  ones; 
  length 
  of 
  spires 
  equal 
  to 
  

   the 
  diameter 
  of 
  the 
  body. 
  The 
  head 
  is 
  red 
  with 
  black 
  ocelli, 
  the 
  

   mandibles 
  black-tipped, 
  and 
  with 
  a 
  few 
  perpendicular 
  black 
  lines 
  on 
  the 
  

   clypeus. 
  On 
  the 
  5th 
  the 
  more 
  advanced 
  larvae 
  show 
  the 
  red 
  ring 
  on 
  the
