﻿PEOCEEDINGS 
  OF 
  THE 
  POURTH 
  ENTOMOLOGICAL 
  MEETING 
  155 
  

  

  segments. 
  Larva 
  is 
  beset 
  with 
  spiniferous 
  processes 
  placed 
  in 
  four 
  

   rows, 
  2 
  lateral, 
  2 
  subdorsal. 
  The 
  spines 
  are 
  bifid 
  at 
  the 
  tip. 
  The 
  head 
  

   is 
  hidden 
  by 
  the 
  projecting 
  prothoracic 
  shield 
  and 
  the 
  anterior 
  s^jines. 
  

   It 
  is 
  strongly 
  mandibulate 
  and 
  has 
  singularly 
  large 
  legs. 
  Prolegs 
  

   absent 
  and 
  replaced 
  by 
  the 
  foot 
  typical 
  of 
  Limacodids.

  Larval 
  life. 
  After 
  first 
  moult 
  which 
  takes 
  place 
  in 
  48 
  hours 
  from, 
  

   the 
  time 
  of 
  hatching 
  the 
  larva 
  is 
  1-4 
  mm. 
  in 
  length. 
  The 
  colour 
  bands 
  

   have 
  deepened 
  and 
  concentrated. 
  Spiniferous 
  tubercles 
  are 
  a 
  quite 
  

   difierent 
  shape. 
  Central 
  spine 
  is 
  not 
  bifid 
  and 
  there 
  are 
  two 
  circles 
  of 
  

   strong 
  dark 
  spines 
  surrounding 
  base 
  of 
  central 
  spine, 
  

   r 
  In 
  another 
  48 
  hours 
  larva 
  moults 
  again. 
  It 
  is 
  now 
  2-2 
  mm. 
  long. 
  

   Colour 
  is 
  greener, 
  dorso-lateral 
  colour 
  band 
  deeper 
  in 
  colour 
  and 
  more 
  

   concentrated. 
  

  

  Next 
  moult 
  (48 
  hours) 
  length 
  3 
  mm. 
  Dorsal 
  spiniferous 
  tubercles 
  

   are 
  white 
  with 
  black 
  spines. 
  First 
  three 
  lateral 
  spines 
  white, 
  tubercles 
  

   black, 
  anal 
  tubercles 
  have 
  black 
  spines, 
  others 
  colourless. 
  

  

  When 
  5-5 
  mm. 
  in 
  length 
  body 
  is 
  green 
  above 
  with 
  dorsal 
  stripe 
  of 
  

   anterior 
  |- 
  greenish 
  bordered 
  by 
  pink 
  and 
  yellow 
  streak, 
  post. 
  | 
  purplish 
  

   bordered 
  by 
  yellow, 
  this 
  is 
  constricted 
  in 
  two 
  places 
  by 
  the 
  yellow 
  encro- 
  

   aching 
  upon 
  the 
  purple 
  dividing 
  it 
  into 
  3 
  parts. 
  Tubercles 
  have 
  several 
  

   rows 
  of 
  spines 
  ; 
  terminal 
  spines 
  long 
  and 
  white 
  (pale) 
  3 
  anterior 
  tubercles 
  

   darker. 
  

  

  Full-grown 
  larva, 
  8-11 
  mm. 
  in 
  length. 
  

  

  General 
  ground 
  colour 
  apple 
  green. 
  3 
  anterior 
  spiniferous 
  processes 
  

   rose 
  colour 
  or, 
  and 
  more 
  usually, 
  bright 
  crimson. 
  

  

  Eunning 
  fore 
  and 
  aft 
  a 
  pair 
  of 
  bright 
  yellow 
  streaks 
  placed 
  latero-dors- 
  

   ally 
  along 
  the 
  bases 
  of 
  the 
  latero-dorsal 
  rows 
  of 
  processes 
  placed 
  between 
  

   the 
  two 
  rows 
  of 
  latero-dorsal 
  processes 
  are 
  three 
  lozenge-shaped 
  

   patches 
  of 
  bright 
  crimson 
  between 
  segments 
  I 
  and 
  III, 
  V, 
  VI, 
  and 
  on 
  

   VII. 
  Lozenges 
  are 
  separated 
  by 
  green, 
  or 
  by 
  dilations 
  of 
  the 
  yellow 
  

   streaks. 
  There 
  is 
  faint 
  mid-dorsal 
  narrow 
  yellow 
  streak. 
  This 
  is 
  the 
  

   average 
  typical 
  specimen. 
  

  

  In 
  some 
  the 
  crimson 
  patch 
  occupies 
  the 
  greater 
  part 
  of 
  the 
  mid- 
  

   dorsal 
  area 
  — 
  the 
  three 
  lozenges 
  forming 
  one 
  stripe 
  and 
  extending 
  for- 
  

   ward 
  along 
  the 
  yellow 
  streaks 
  and 
  enclosing 
  a 
  median 
  green 
  patch 
  j 
  oining 
  

   with 
  the 
  red 
  of 
  the 
  anterior 
  tubercles. 
  In 
  others 
  again 
  the 
  two 
  posterior 
  

   lozenges 
  coalesce, 
  leaving 
  the 
  anterior 
  one 
  separate. 
  Again, 
  two 
  red 
  

   spots 
  mark 
  the 
  position 
  which 
  should 
  have 
  been 
  held 
  by 
  the 
  lozenges, 
  

   the 
  remainder 
  of 
  the 
  space 
  being 
  green. 
  Finally, 
  some 
  show 
  no 
  trace 
  of 
  

   red 
  lozenge-shaped 
  patches 
  ; 
  the 
  larva 
  is 
  entirely 
  green 
  except 
  for 
  a 
  pair 
  

   of 
  latero-dorsal 
  yellow 
  stripes.
