  than 
  in 
  adult, 
  and 
  are 
  very

  (Bacot,

  Third 
  or 
  Fourth 
  instar

  4'5mm. 
  long, 
  and 
  about 
  0'7mm. 
  

   thick 
  in 
  thoracic 
  and 
  first 
  two 
  or 
  three 
  abdominal 
  segments, 
  thence 
  

   tapering 
  very 
  slightly 
  to 
  last 
  segments. 
  Colour, 
  a 
  green 
  very 
  close 
  to 
  

   that 
  of 
  the 
  leaves 
  of 
  the 
  Statice, 
  with 
  two 
  red 
  prominences 
  on 
  prothorax, 
  

   projecting 
  forwards 
  over 
  head, 
  and 
  one 
  caudal 
  on 
  9th 
  abdominal 
  pro- 
  

   jecting 
  backwards 
  — 
  the 
  head 
  and 
  1st 
  thoracic 
  and 
  the 
  9th 
  and 
  10th 
  

   abdominal 
  are 
  reddish, 
  or 
  strongly 
  marked 
  with 
  pink, 
  giving 
  a 
  very 
  

   marked 
  character 
  to 
  the 
  larva, 
  with 
  the 
  double 
  front 
  horn 
  and 
  the 
  

   single 
  one 
  behind. 
  The 
  head 
  is 
  carried 
  in 
  the 
  manner 
  we 
  are 
  familiar 
  

   with 
  in 
  drawings 
  of 
  the 
  larva 
  of 
  Apatura 
  iris, 
  the 
  vertex 
  thrown 
  

   forward, 
  the 
  mouth 
  retracted, 
  so 
  that 
  the 
  horns 
  on 
  prothorax 
  (on 
  head 
  

   in 
  A. 
  iris) 
  am 
  pointed 
  directly 
  forward 
  and 
  project 
  in 
  front 
  of 
  the 
  head. 
  

   These 
  horns 
  have 
  each 
  a 
  tubercle 
  at 
  apex 
  and 
  one 
  on 
  outer 
  flank. 
  

   They 
  are 
  short 
  hairs, 
  Indian 
  club-shaped, 
  as 
  are 
  more 
  or 
  less 
  all 
  the 
  

   others. 
  The 
  caudal 
  horn 
  (on 
  9th 
  abdominal) 
  has 
  two 
  tubercles 
  at 
  its 
  

   extremity, 
  or 
  one 
  might 
  say 
  at 
  the 
  lateral 
  margins 
  of 
  the 
  rounded 
  end, 
  

   and 
  one 
  other 
  on 
  each 
  side 
  near 
  its 
  base. 
  The 
  prothorax 
  has, 
  just 
  

   below 
  and 
  behind 
  the 
  bases 
  of 
  the 
  horns, 
  which 
  occupy 
  the 
  whole 
  

   dome 
  of 
  the 
  segment 
  (much 
  of 
  the 
  area 
  often 
  covered 
  by 
  the 
  prothoracic 
  

   plate), 
  a 
  large, 
  dark, 
  conical 
  prominence, 
  carrying 
  on 
  its 
  summit 
  the 
  

   first 
  spiracle, 
  marked 
  by 
  several 
  alternate 
  white 
  and 
  black 
  rings, 
  some 
  

   possibly 
  the 
  effect 
  of 
  reflection 
  from 
  a 
  polished 
  surface. 
  Well 
  below 
  

   and 
  in 
  front 
  of 
  this 
  is 
  a 
  black 
  tubercle, 
  with 
  a 
  true 
  bristle, 
  about 
  three 
  

   times 
  as 
  long 
  as 
  the 
  clubbed 
  hairs, 
  and 
  quite 
  unlike 
  them, 
  but 
  like 
  

   those 
  on 
  anal 
  plate. 
  The 
  head 
  is 
  yellow, 
  with 
  a 
  network 
  of 
  red 
  lines 
  of 
  

   smallish 
  mesh, 
  the 
  lines 
  themselves 
  comparatively 
  broadish. 
  On 
  the 
  

   head 
  are 
  a 
  good 
  many 
  slightly 
  clubbed 
  bristles. 
  The 
  ocelli 
  are 
  five 
  in 
  

   a 
  semicircle 
  (the 
  three 
  lowest 
  rather 
  perhaps 
  in 
  line) 
  with 
  a 
  sixth 
  

   centrally 
  placed. 
  The 
  other 
  spiracles 
  are 
  placed 
  on 
  dark, 
  raised, 
  

   smooth 
  mammillae, 
  smaller, 
  however, 
  than 
  that 
  on 
  first 
  thoracic, 
  that 
  

   on 
  8th 
  abdominal, 
  however, 
  nearly 
  as 
  large. 
  The 
  whole 
  scale 
  is 
  micro- 
  

   scopic, 
  but 
  either 
  extremity 
  looks 
  something 
  like 
  a 
  vertebrate 
  head, 
  with 
  

   the 
  horns 
  for 
  snout, 
  or 
  upper 
  jaw 
  of 
  an 
  open 
  mouth, 
  and 
  the 
  spiracles 
  

   as 
  eyes. 
  The 
  10th 
  abdominal 
  (anal 
  plate) 
  has 
  four 
  marginal 
  bristles 
  

   nearly 
  equal 
  to 
  that 
  on 
  prothorax, 
  seated 
  on 
  slightly 
  raised 
  bases 
  ; 
  it 
  carries 
  

   an 
  ordinary 
  tubercle 
  above 
  (just 
  behind 
  the 
  horn 
  of 
  the 
  9th 
  abdominal) 
  ; 
  

   there 
  is 
  a 
  bristle 
  nearly 
  equal 
  to 
  these 
  on 
  the 
  outer 
  aspect 
  of 
  the 
  base 
  of 
  the 
  

   clasper. 
  The 
  whole 
  surface 
  of 
  the 
  larva 
  has, 
  besides 
  the 
  spiracles 
  and 
  

   tubercles 
  (yet 
  to 
  be 
  noted), 
  a 
  large 
  covering 
  of 
  hair-points 
  of 
  two 
  kinds. 
  

   Certainly 
  most 
  of 
  these 
  do 
  not 
  carry 
  any 
  sort 
  of 
  hair, 
  but 
  some 
  appear 
  to 
  

   terminate 
  in 
  a 
  sharp 
  point. 
  The 
  one 
  kind 
  are 
  white 
  or 
  porcellanous, 
  look- 
  

   ing 
  like 
  raised 
  polished 
  buttons, 
  of 
  which 
  there 
  are 
  perhaps 
  80, 
  between 
  

   dorsum 
  and 
  spiracular 
  level, 
  on 
  one 
  side 
  of 
  an 
  abdominal 
  segment. 
  

   They 
  can 
  be 
  seen 
  with 
  a 
  hand 
  lens 
  as 
  minute 
  white 
  Jots 
  tending 
  to 
  

   fall 
  into 
  transverse 
  rows. 
  The 
  others 
  are 
  much 
  more 
  numerous 
  and 
  

   only 
  about 
  .V 
  to 
  £ 
  the 
  diameter 
  of 
  the 
  white 
  ones, 
  and 
  are 
  black, 
  

   though 
  a 
  few 
  are 
  rather 
  paler, 
  and 
  some 
  of 
  the 
  ground 
  colour, 
  but 
  still 
  

   prominent 
  little 
  buttons. 
  These 
  black 
  points 
  are 
  convex 
  polished 
  

   projections, 
  like 
  the 
  white 
  ones, 
  tend 
  to 
  tall 
  into 
  transverse 
  and 
  

   oblique 
  rows, 
  and 
  are 
  about 
  their 
  own 
  diameters 
  apart. 
  There 
  may 
  

   be, 
  perhaps, 
  250 
  on 
  the 
  area, 
  from 
  spiracle 
  to 
  dorsum 
  of 
  an 
  abdominal 
  

   segment. 
  Below 
  the 
  spiracles 
  is 
  a 
  paler 
  whitish 
  band, 
  this 
  has 
  a
