  BRITISH

  also 
  dark, 
  but 
  the 
  rest 
  of 
  the 
  head 
  and 
  prothorax 
  are 
  freer 
  from 
  dark 
  

   markings 
  than 
  any 
  other 
  part 
  of 
  the 
  pupa. 
  In 
  the 
  dark 
  form 
  the 
  

   appendages 
  are 
  nearly 
  black, 
  but 
  are, 
  perhaps, 
  more 
  strictly 
  dark 
  green 
  

   or 
  brown-green, 
  the 
  head 
  and 
  prothorax 
  more 
  nearly 
  resemble 
  the 
  

   pale 
  form 
  than 
  any 
  other 
  portion 
  of 
  the 
  pupa, 
  with 
  a 
  good 
  deal 
  of 
  

   green 
  and 
  white 
  over 
  the 
  pro- 
  and 
  mesothorax. 
  The 
  rest 
  of 
  the 
  pupa 
  

   is 
  a 
  deep 
  ruddy 
  brown, 
  as 
  if 
  the 
  colour 
  of 
  the 
  incisions 
  of 
  the 
  pale 
  

   form 
  had 
  here 
  spread 
  and 
  overwhelmed 
  everything. 
  The 
  white 
  dots 
  

   are 
  still 
  paler 
  along 
  the 
  fine 
  ridges, 
  but 
  the 
  dark 
  marblings 
  are 
  

   wanting 
  at 
  first 
  view, 
  yet 
  exist 
  as 
  two 
  anterior 
  (close) 
  and 
  two 
  pos- 
  

   terior 
  (further 
  apart) 
  dark 
  spots 
  dorsally, 
  and 
  two 
  subdorsal 
  wavy 
  lines 
  

   (one 
  below 
  the 
  other) 
  on 
  each 
  side, 
  with 
  other 
  less 
  definite 
  markings. 
  

   The 
  posterior 
  half 
  of 
  the 
  dorsum 
  of 
  each 
  segment 
  (2nd-7th 
  abdominal) 
  is 
  

   paler 
  than 
  the 
  rest, 
  and 
  so 
  shows 
  up 
  more 
  definitely 
  the 
  two 
  posterior 
  

   dark 
  spots 
  which 
  it 
  encloses, 
  and 
  the 
  upper 
  of 
  the 
  subdorsal 
  bands 
  

   which 
  bound 
  it 
  laterally.

  Time 
  of 
  appearance. 
  — 
  The

  variation
