  BRITISH 
  LEPIDOPTERA. 
  

  

  hairs, 
  about 
  O'lmm. 
  long, 
  faintly 
  reddish- 
  brown, 
  darker 
  at 
  the 
  tips, 
  

   which 
  are 
  swollen 
  as 
  if 
  recurved, 
  and 
  a 
  sharp 
  point 
  directed 
  basally. 
  

   The 
  ventral 
  cremaster 
  has 
  exactly 
  similar 
  hooks, 
  but 
  comparatively 
  few 
  

   in 
  number 
  (Chapman, 
  June 
  27th, 
  1905). 
  Length 
  of 
  pupa 
  measures 
  

   between 
  8mm. 
  and 
  9mm. 
  ; 
  width 
  at 
  mesothorax 
  and 
  5th 
  abdominal 
  about 
  

   l-75mm., 
  and 
  thickness 
  rather 
  less; 
  the 
  pupa 
  below 
  the 
  wingcases 
  

   is 
  nearly 
  cylindrical. 
  It 
  is 
  very 
  distinctively 
  coloured 
  — 
  pale 
  whitish- 
  

   green, 
  with 
  a 
  dark 
  green 
  dorsal 
  band, 
  which 
  is 
  interrupted 
  and 
  broken 
  

   towards 
  the 
  anus. 
  The 
  wings 
  are 
  outlined 
  by 
  a 
  narrow 
  streak 
  of 
  dark 
  

   green, 
  and 
  delicately 
  shaded 
  towards 
  their 
  extremities 
  with 
  soft 
  green, 
  

   not 
  so 
  dark 
  as 
  the 
  surrounding 
  line. 
  The 
  whole 
  of 
  the 
  head-pieces, 
  

   eye-cases, 
  leg- 
  and 
  antenna-cases, 
  are 
  dark 
  green, 
  and 
  show 
  up 
  as 
  a 
  

   most 
  conspicuous 
  shield. 
  Some 
  fainter 
  green 
  shading 
  is 
  also 
  present 
  

   at 
  base 
  of 
  wings, 
  and 
  on 
  the 
  thoracic 
  segments 
  dorsally, 
  as 
  well 
  as 
  a 
  

   much 
  broken 
  and 
  interrupted 
  faint 
  subdorsal 
  line 
  of 
  delicate 
  green, 
  

   which 
  shows 
  towards 
  anal 
  end 
  of 
  abdominal 
  segments. 
  There 
  is 
  a 
  

   stronger, 
  but 
  still 
  broken, 
  lateral 
  band, 
  and 
  also 
  a 
  subventral 
  one, 
  and 
  

   the 
  area 
  immediately 
  surrounding 
  the 
  spiracles 
  is 
  faintly 
  tinged 
  with 
  

   darker 
  green. 
  The 
  spiracles 
  are 
  large, 
  and 
  rather 
  prominent, 
  but 
  are 
  

   not 
  raised 
  to 
  anything 
  like 
  the 
  extent 
  that 
  they 
  are 
  in 
  Ovendenia 
  

   septodactyla 
  (lienigianus) 
  , 
  or 
  even 
  Oidaematophorus 
  lithodactyla. 
  The 
  

   hairs 
  are 
  long 
  and 
  tapering, 
  either 
  quite 
  simple, 
  or 
  very 
  finely 
  serrated, 
  

   probably 
  the 
  latter, 
  as 
  they 
  seem 
  to 
  pick 
  up 
  dust 
  very 
  readily. 
  No 
  

   secondaries 
  are 
  present 
  on 
  abdominal 
  segments 
  ; 
  nor 
  are 
  there 
  the 
  

   fringes 
  of 
  fine 
  hairs 
  on 
  the 
  wing-, 
  leg-, 
  or 
  antenna-cases, 
  like 
  those 
  found 
  

   in 
  the 
  pupse 
  of 
  Porrittia 
  galactodactyla, 
  Oidaematophorus 
  lithodactyla, 
  

   and 
  Ovendenia 
  septodactyla. 
  All 
  tubercles 
  are 
  single-haired, 
  as 
  in 
  the 
  

   larva, 
  the 
  tubercles 
  at 
  base 
  being 
  primitive 
  and 
  cone-shaped 
  ; 
  i 
  and 
  ii 
  

   are 
  a 
  short 
  distance 
  apart 
  on 
  a 
  single 
  longitudinal 
  mound; 
  they 
  are 
  

   much 
  farther 
  apart 
  on 
  the 
  1st 
  and 
  2nd 
  abdominal 
  segments 
  than 
  on 
  

   the 
  following 
  one, 
  and 
  the 
  ridge 
  becomes 
  more 
  definite, 
  and 
  continues 
  

   nearly 
  the 
  whole 
  length 
  of 
  the 
  segment, 
  becoming 
  higher 
  and 
  converging 
  

   towards 
  the 
  mediodorsal 
  line, 
  culminating 
  in 
  a 
  twin 
  ridge 
  or 
  process 
  on 
  

   the 
  mesothorax 
  ; 
  i 
  bears 
  a 
  long 
  hair 
  lying 
  forwards 
  ; 
  ii 
  a 
  very 
  much 
  longer 
  

   hair, 
  pointing 
  backwards 
  ; 
  iii 
  is 
  a 
  short 
  distance 
  above, 
  and 
  slightly 
  

   posterior 
  to 
  spiracle, 
  bearing 
  a 
  hair 
  of 
  about 
  equal 
  length 
  to 
  i, 
  bending 
  

   forwards 
  ; 
  iv 
  and 
  v 
  are 
  well 
  separated 
  ; 
  v, 
  exactly 
  subspiracular, 
  bears 
  

   the 
  smaller 
  hair; 
  iv, 
  posterior 
  to 
  spiracle, 
  but 
  nearly 
  in 
  same 
  horizontal 
  

   plane, 
  bears 
  a 
  longer 
  hair 
  ; 
  iv 
  slopes 
  ventrally 
  ; 
  v 
  slopes 
  forwards 
  ; 
  vi 
  

   carries 
  a 
  single 
  hair, 
  beneath 
  iv; 
  and 
  vii, 
  marginal, 
  consists 
  of 
  3 
  hairs 
  in 
  

   line". 
  The 
  pupa-case 
  is 
  very 
  thin 
  and 
  semitransparent 
  in 
  parts, 
  ex- 
  

   ceedingly 
  finely 
  striated 
  or 
  wrinkled 
  transversely. 
  This 
  is 
  also 
  a 
  

   feature 
  of 
  the 
  other 
  species, 
  and 
  is 
  well-marked 
  in 
  the 
  pupse 
  of 
  

   Ovendenia 
  septodactyla 
  {lienigianus) 
  and 
  Porrittia 
  galactodactyla, 
  but 
  the 
  

   wrinkles 
  are 
  large 
  and 
  coarse 
  in 
  Oidaematophorus 
  lithodactyla. 
  They 
  

   are 
  also 
  present 
  in 
  the 
  pupa 
  of 
  Adactylus 
  bennetii, 
  and 
  are 
  very 
  

   fine 
  in 
  this 
  species 
  and 
  more 
  regular 
  than 
  in 
  others

  additional 
  notes 
  made 
  from 
  empty 
  pupa-cases,

  (Bacot).

  says 
  : 
  " 
  The 
  pupa 
  is

  Barrett 
  says 
  (Ley. 
  Brit. 
  Isles, 
  ix., 
  p. 
  345) 
  that 
  " 
  the 
  pupa 
  is 
  curiously 
  

   sprinkled 
  with 
  fine 
  hairs 
  or 
  long 
  bristles, 
  especially 
  on 
  the 
  dorsal 
  surface." 
  The 
  

   " 
  curiously 
  sprinkled 
  hairs 
  " 
  appear 
  to 
  be 
  the 
  ordinary 
  pupal 
  setae, 
  in 
  normal 
  

   position.
