  a 
  most 
  delicate 
  yellow-green 
  colour, 
  the 
  tips 
  of 
  the 
  limbs 
  and 
  the 
  anal 
  

   segment 
  being 
  somewhat 
  transparent 
  yellow 
  ; 
  no 
  dark 
  markings 
  any- 
  

   where 
  on 
  the 
  pupa 
  except 
  a 
  tiny 
  black 
  point 
  within 
  the 
  eye-collar 
  ; 
  two 
  

   slender, 
  whitish, 
  subdorsal 
  lines 
  on 
  either 
  side 
  of 
  a 
  fine 
  mediodorsal 
  

   line, 
  rather 
  darker 
  than 
  the 
  ground-colour, 
  and 
  a 
  somewhat 
  similar 
  

   prominent 
  subspiracular 
  line 
  slightly 
  raised, 
  representing 
  the 
  larval 
  

   subspiracular 
  flange 
  ; 
  the 
  shiny 
  spiracles 
  very 
  conspicuous, 
  also 
  

   the 
  distinct 
  transverse 
  wrinkling 
  ; 
  the 
  abdominal 
  segmental 
  incisions 
  

   of 
  a 
  bright 
  yellow 
  colour 
  (Tutt, 
  May 
  20th,

  Colour 
  changes 
  

   on 
  maturation 
  (June 
  4th, 
  1904) 
  : 
  By 
  June 
  4th 
  the 
  oldest 
  pupa 
  

   had 
  undergone 
  considerable 
  change. 
  It 
  was 
  now 
  much 
  paler 
  in 
  

   tint. 
  The 
  eyes 
  were 
  quite 
  dark, 
  of 
  a 
  greyish-black 
  tint, 
  the 
  legs, 
  etc., 
  

   whitish 
  ; 
  the 
  thorax 
  also 
  was 
  paler, 
  and 
  the 
  green 
  of 
  the 
  abdomen 
  

   rather 
  duller 
  in 
  tint. 
  The 
  double 
  dorsal 
  ridge 
  (containing 
  the 
  medio- 
  

   dorsal 
  depression) 
  was 
  also 
  pale 
  in 
  tint, 
  and 
  the 
  character 
  of 
  the 
  ridges 
  on 
  

   the 
  thoracic 
  segments, 
  uniting 
  almost 
  on 
  the 
  summit 
  of 
  the 
  mesothorax, 
  

   widening 
  again 
  from 
  hence 
  as 
  they 
  pass 
  back 
  over 
  the 
  abdominal 
  segments, 
  

   gave 
  an 
  unmistakable 
  suggestion 
  of 
  the 
  same 
  character 
  (still 
  more 
  

   marked, 
  however, 
  than 
  in 
  this 
  species) 
  in 
  Gillmeria 
  ochrodactyla 
  and 
  G. 
  

   pallidactyla. 
  Final 
  appearances: 
  June 
  8th, 
  the 
  wings 
  turning- 
  

   brown. 
  June 
  10th, 
  the 
  wings 
  and 
  appendages 
  quite 
  dark 
  ; 
  the 
  tiny 
  

   slip 
  of 
  hindwing, 
  lying 
  along 
  inner 
  margin 
  of 
  forewing, 
  almost 
  black 
  ; 
  

   the 
  thoracic 
  segments 
  also 
  brown, 
  the 
  mesothorax 
  rather 
  browner 
  than 
  

   the 
  pro- 
  and 
  metathorax. 
  (Imago 
  emerged 
  in 
  the 
  early 
  morning, 
  

   before 
  8 
  a.m., 
  of 
  June 
  12th.) 
  Another 
  pupa, 
  on 
  June 
  12th, 
  showed 
  

   the 
  wings 
  dark 
  ; 
  the 
  narrow 
  slip 
  of 
  hindwings 
  blackish 
  ; 
  the 
  apex 
  of 
  

   mesothorax 
  dark 
  ; 
  the 
  rest 
  of 
  the 
  thorax 
  and 
  abdomen 
  pale 
  brown, 
  

   except 
  the 
  movable 
  abdominal 
  incisions 
  which 
  appeared 
  greenish 
  

   (Imago 
  emerged 
  from 
  this 
  pupa 
  on 
  June 
  13th.) 
  (Tutt). 
  

  

  Pupa. 
  — 
  Length 
  of 
  pupa 
  10*5mm., 
  width 
  at 
  thorax 
  2mm., 
  at 
  4th 
  

   abdominal, 
  l-6mm. 
  Form 
  and 
  structure 
  almost 
  identical 
  with 
  that 
  of 
  

   Adkinia 
  bipunctidactyla, 
  and 
  the 
  colouring 
  is 
  also 
  very 
  close. 
  The 
  

   peculiar 
  character 
  of 
  the 
  tubercles, 
  with 
  their 
  globular 
  bases, 
  and 
  the 
  

   hairs 
  situated 
  on 
  their 
  anterior 
  (or 
  posterior) 
  faces, 
  instead 
  of 
  springing 
  

   from 
  the 
  top, 
  are 
  precisely 
  the 
  same. 
  The 
  pupa 
  is 
  also 
  very 
  like 
  that 
  

   of 
  A. 
  zojihodactylus, 
  a 
  little 
  larger, 
  about 
  12mm. 
  long, 
  equally 
  cylindrical, 
  

   and 
  nearly 
  as 
  slender 
  ; 
  its 
  colour, 
  however, 
  is 
  less 
  brilliant. 
  There 
  is 
  

   a 
  little 
  rise 
  to 
  the 
  top 
  of 
  the 
  mesothorax, 
  but 
  otherwise 
  the 
  pupa 
  tapers 
  

   equally, 
  and 
  very 
  slightly, 
  from 
  the 
  mesothorax 
  backwards, 
  more 
  

   rapidly, 
  however, 
  on 
  abdominal 
  segments 
  8, 
  9, 
  and 
  10, 
  which 
  run 
  to 
  a 
  

   sharp 
  point, 
  and, 
  with 
  two 
  subdorsal 
  and 
  two 
  subspiracular 
  ridges 
  

   very 
  pronounced, 
  give 
  a 
  quadrangular 
  section. 
  The 
  dorsal 
  ridges 
  in 
  

   front 
  are 
  well-marked, 
  smooth, 
  and 
  rounded, 
  except 
  on 
  posterior 
  slope 
  

   of 
  mesothorax, 
  where 
  there 
  is 
  some 
  crenulation 
  ; 
  they 
  are 
  very 
  close 
  

   together 
  here, 
  but 
  separate 
  both 
  in 
  front 
  and 
  behind. 
  They 
  run 
  back 
  

   and 
  include 
  i 
  of 
  the 
  3rd 
  abdominal 
  segment, 
  stopping 
  there 
  

   abruptly, 
  although 
  ii 
  is 
  in 
  the 
  same 
  line, 
  and 
  only 
  separated 
  from 
  i 
  by 
  

   two 
  of 
  the 
  narrow 
  transverse 
  ribs. 
  The 
  tubercles 
  i 
  and 
  ii 
  arise 
  from 
  

   the 
  front 
  and 
  back 
  respectively 
  of 
  two 
  of 
  these 
  ribs, 
  with 
  two 
  between; 
  

   the 
  ribs 
  they 
  arise 
  from 
  here 
  project 
  almost 
  as 
  a 
  little 
  ball, 
  and 
  the 
  

   hair 
  comes 
  from 
  quite 
  the 
  side 
  of 
  it, 
  and 
  is 
  nearly 
  parallel 
  with 
  the 
  

   pupal 
  surface, 
  i 
  pointing 
  forwards, 
  ii 
  backwards. 
  They 
  are 
  all 
  minute 
  

   clubbed 
  batons, 
  about 
  0'03mm. 
  long. 
  It 
  is 
  curious 
  how 
  they 
  suggest,
