  LEPIDOPTEKA. 
  

  

  one, 
  but 
  looks 
  less 
  so 
  as 
  it 
  wants 
  the 
  high 
  spine, 
  which 
  exists 
  on 
  the 
  

   3rd, 
  but 
  not 
  on 
  the 
  2nd, 
  abdominal 
  segment. 
  The 
  beak, 
  antenna-bases 
  

   (where 
  they 
  contribute 
  to 
  dorsal 
  flange), 
  and 
  dorsal 
  flange 
  in 
  front 
  of 
  the 
  

   mesothorax, 
  are 
  whitish, 
  almost 
  porcellanous. 
  The 
  remainder 
  of 
  the 
  

   flange 
  is 
  tinted 
  with 
  brownish-pink, 
  as 
  are 
  the 
  dorsal 
  spines 
  of 
  the 
  4th, 
  

   5th, 
  and 
  6th 
  abdominal 
  segments 
  ; 
  the 
  tip 
  of 
  the 
  appendage-case 
  is 
  

   fuscous. 
  The 
  lateral 
  abdominal 
  flange 
  is 
  whitish, 
  and 
  the 
  abdomen 
  

   looks 
  white 
  above 
  spiracles, 
  but 
  between 
  the 
  oblique 
  lines 
  is 
  more 
  bright. 
  

   There 
  is 
  a 
  darker 
  green 
  dorsal 
  line, 
  and 
  oblique 
  (downwards 
  and 
  back- 
  

   wards, 
  as 
  in 
  larva) 
  green 
  lines 
  pass 
  through 
  this, 
  or 
  rather 
  from 
  the 
  

   dorsal 
  abdominal 
  spines. 
  The 
  8th, 
  9th, 
  and 
  10th 
  abdominal 
  segments 
  

   are 
  faintly 
  brownish. 
  (2) 
  To 
  take 
  now 
  a 
  very 
  dark 
  example, 
  the 
  colours 
  

   are 
  terra-cotta, 
  pink, 
  and 
  black, 
  the 
  last, 
  in 
  places, 
  as 
  if 
  it 
  were 
  thinly 
  

   laid 
  on, 
  so 
  as 
  to 
  be 
  dark 
  fuscous. 
  Green 
  is 
  still 
  present 
  on 
  the 
  4th, 
  

   5th, 
  and 
  6th 
  abdominal 
  segments, 
  but 
  is 
  really 
  (as 
  it 
  looks) 
  the 
  green 
  

   interior 
  seen 
  through 
  the 
  pinkish 
  cuticle. 
  White 
  is 
  present 
  along 
  the 
  edge 
  

   of 
  flange 
  in 
  front 
  of 
  mesothorax, 
  and 
  on 
  the 
  tips 
  of 
  spines 
  and 
  hair-points, 
  

   except 
  the 
  large 
  spine 
  of 
  the 
  3rd 
  abdominal 
  segment, 
  where 
  the 
  tip 
  is 
  

   brown. 
  These 
  amounts 
  of 
  white 
  and 
  green 
  are 
  too 
  small 
  to 
  produce 
  

   any 
  effect 
  on 
  the 
  general 
  appearance 
  of 
  the 
  pupa, 
  except, 
  perhaps, 
  to 
  

   give 
  it 
  a 
  little 
  brilliance. 
  Pink 
  is 
  the 
  prevailing 
  ground 
  colour, 
  but 
  with 
  

   an 
  underlying 
  olive, 
  and 
  with 
  abundant, 
  dark, 
  nearly 
  black, 
  markings. 
  

   The 
  dark 
  marks, 
  running 
  obliquely 
  forward 
  on 
  the 
  2nd 
  and 
  3rd 
  abdominal 
  

   segments, 
  are 
  very 
  large, 
  and 
  practically 
  absorb 
  all 
  the 
  wing-surface, 
  

   which, 
  however, 
  has 
  some 
  olive 
  lines 
  between 
  the 
  veins, 
  towards 
  the 
  

   hindmargin 
  ; 
  the 
  olive 
  tint 
  of 
  the 
  appendages 
  is 
  overlaid 
  with 
  fuscous, 
  and 
  

   shows 
  darker 
  bands 
  at 
  intervals 
  ; 
  the 
  4th, 
  5th, 
  and 
  6th 
  abdominal 
  

   segments 
  have 
  markings 
  that 
  are 
  also 
  apparently 
  present 
  in 
  

   front, 
  but 
  are 
  obscured 
  by 
  flange, 
  spine, 
  and 
  appendages; 
  a 
  dark 
  

   dorsal 
  line, 
  a 
  dark 
  supraspiracular 
  line, 
  and 
  another 
  between 
  these, 
  

   somewhat 
  interrupted 
  ; 
  below 
  iv 
  and 
  v 
  are 
  two 
  broad 
  dark 
  bands, 
  meeting 
  

   somewhat 
  in 
  the 
  middle 
  of 
  each 
  segment, 
  so 
  as 
  almost 
  to 
  form 
  one 
  very 
  

   broad 
  band. 
  Ventrally, 
  there 
  is 
  another 
  dark 
  band 
  on 
  either 
  side. 
  

   Except 
  subdorsally 
  and 
  ventrally, 
  the 
  ground 
  colour 
  is 
  wanting 
  on 
  the 
  

   8th, 
  9th, 
  and 
  10th 
  abdominal 
  segments. 
  The 
  most 
  striking 
  feature 
  

   of 
  this 
  pupa 
  (as 
  in 
  that 
  of 
  Marasmarcha 
  lunaedactyla) 
  is 
  the 
  great 
  

   spine 
  on 
  the 
  3rd 
  abdominal 
  segment. 
  This 
  may 
  be 
  described 
  as 
  the 
  

   base 
  of 
  tubercle 
  i 
  of 
  that 
  segment. 
  The 
  pupa 
  is 
  here 
  about 
  l-5mm. 
  

   thick, 
  and 
  the 
  spine 
  stands 
  up 
  about 
  0*7mm. 
  The 
  double 
  dorsal 
  flange 
  

   of 
  the 
  front 
  segments 
  runs 
  down 
  the 
  3rd 
  abdominal 
  segment 
  directly 
  

   to 
  the 
  spine, 
  which 
  has 
  the 
  appearance 
  of 
  being 
  its 
  culmination. 
  The 
  

   ridge 
  of 
  the 
  flange 
  forms 
  a 
  curve 
  along 
  the 
  front 
  of 
  the 
  spine 
  until 
  its 
  

   extremity 
  is 
  directed 
  forwards 
  as 
  a 
  sharp 
  hook. 
  This 
  hook 
  is 
  not 
  the 
  

   tubercle 
  ; 
  at 
  least, 
  the 
  hair 
  of 
  tubercle 
  i 
  stands 
  on 
  the 
  front 
  margin 
  of 
  

   the 
  spine, 
  about 
  two-fifths 
  of 
  its 
  length 
  from 
  the 
  base. 
  The 
  spine 
  is 
  

   very 
  flattened 
  from 
  side 
  to 
  side, 
  and 
  has 
  an 
  irregular 
  flange- 
  like 
  

   extension 
  on 
  its 
  posterior 
  margin 
  ; 
  tubercle 
  ii 
  is 
  not 
  on 
  this 
  spine, 
  but 
  

   on 
  a 
  conical 
  offset 
  from 
  its 
  posterior 
  base. 
  It 
  might 
  be 
  said 
  that 
  ii 
  

   emulates 
  i, 
  and, 
  without 
  quite 
  securing 
  a 
  separate 
  base, 
  forms 
  a 
  pointed 
  

   cone, 
  directed 
  a 
  little 
  backwards, 
  and 
  only 
  about 
  one-sixth 
  the 
  length 
  

   of 
  i. 
  The 
  hair 
  of 
  ii 
  arises 
  from 
  quite 
  the 
  base 
  of 
  this 
  cone 
  behind. 
  

   The 
  4th, 
  5th, 
  6th, 
  7th, 
  and 
  8th 
  abdominal 
  segments 
  have 
  precisely 
  

   similar 
  structures, 
  but 
  on 
  a 
  very 
  small 
  scale, 
  and 
  without 
  the 
  dark
