  on 
  all 
  the 
  other 
  abdominal 
  segments, 
  very 
  small 
  on 
  the 
  1st 
  abdominal, 
  

   larger 
  on 
  the 
  2nd, 
  those 
  on 
  the 
  4th 
  three-fourths 
  the 
  size 
  of 
  those 
  no 
  

   the 
  3rd, 
  that 
  on 
  ii 
  being 
  almost 
  as 
  large 
  ; 
  they 
  are 
  still 
  quite 
  pronounced 
  

   on 
  the 
  8th, 
  but 
  are 
  wanting 
  on 
  the 
  9th, 
  abdominal. 
  Along 
  the 
  meso- 
  

   thorax 
  is 
  a 
  pale 
  mediodorsal 
  sutural 
  line; 
  the 
  flanges 
  on 
  each 
  side 
  are 
  

   nodulated 
  in 
  front, 
  but, 
  posteriorly, 
  at 
  highest 
  point 
  of 
  ridges, 
  carry 
  

   two 
  black 
  flattened 
  processes, 
  with 
  a 
  small 
  white 
  one 
  behind, 
  and 
  a 
  

   large 
  flat 
  white 
  one 
  in 
  front. 
  Those 
  further 
  forward, 
  seen 
  in 
  profile, 
  

   look 
  like 
  a 
  serrated 
  alpine 
  ridge 
  covered 
  with 
  snow. 
  The 
  surface- 
  

   sculpturing, 
  as 
  in 
  most 
  of 
  these 
  "plumes," 
  is, 
  firstly, 
  a 
  series 
  of 
  fine 
  

   parallel 
  transverse 
  ridges, 
  too 
  large 
  for 
  sculpturing 
  proper, 
  too 
  small 
  

   and 
  numerous 
  for 
  subsegmentation. 
  There 
  are, 
  for 
  instance, 
  twelve 
  

   or 
  thirteen 
  on 
  the 
  3rd 
  abdominal 
  segment 
  in 
  front 
  of 
  spine. 
  This 
  

   skin-sculpturing 
  is 
  most 
  elaborate 
  and 
  elegant. 
  Across 
  the 
  segment, 
  in 
  

   lieu 
  of 
  the 
  principal 
  processes 
  and 
  tubercles 
  ; 
  the 
  surface 
  is 
  nearly 
  

   smooth 
  and 
  structureless. 
  In 
  front 
  of 
  this 
  are 
  eight 
  or 
  nine 
  transverse 
  

   ridges 
  (on 
  5th 
  abdominal, 
  taken 
  as 
  a 
  sample), 
  of 
  which 
  six 
  or 
  seven 
  are 
  

   very 
  pronounced 
  ; 
  they 
  are 
  narrow 
  and 
  straight, 
  and 
  without 
  any 
  

   waving 
  or 
  side 
  valleys. 
  The 
  whole 
  surface 
  in 
  the 
  valleys, 
  up 
  the 
  

   slopes 
  of 
  the 
  ridges, 
  and 
  where 
  the 
  tops 
  of 
  the 
  ridges 
  are 
  wide 
  

   enough, 
  is 
  covered 
  with 
  fine 
  acuminate 
  skin-points, 
  rather 
  pointing 
  

   backwards, 
  and 
  arranged 
  alternating 
  in 
  rows 
  (not 
  with 
  absolute 
  

   regularity). 
  This 
  sculpturing 
  is 
  all 
  round 
  the 
  segments, 
  but 
  

   is 
  somewhat 
  smoothed 
  down 
  in 
  spiracular 
  region. 
  Behind 
  the 
  

   tubercular 
  and 
  spinous 
  zone 
  is 
  the 
  intersegmental 
  zone, 
  with 
  beautiful 
  

   tessellated 
  pavement, 
  each 
  lozenge 
  of 
  which 
  carries, 
  centrally, 
  a 
  fine 
  

   skin-spicule, 
  pointing 
  backwards 
  ; 
  this 
  has 
  a 
  most 
  unusual 
  effect, 
  and 
  

   one 
  of 
  most 
  orderly 
  regularity. 
  It 
  may 
  be 
  noted 
  that, 
  in 
  a 
  dark 
  pupa, 
  

   met 
  with 
  in 
  examining 
  these 
  structures, 
  the 
  spines 
  of 
  tubercles 
  i 
  and 
  ii 
  

   (most 
  frequently 
  separate), 
  are 
  closely 
  conjoined 
  on 
  all 
  the 
  segments. 
  

   The 
  cremaster 
  is 
  very 
  like 
  that 
  of 
  Amblyptilia 
  cosmodactyla, 
  Hb., 
  with 
  a 
  

   forward 
  portion 
  on 
  the 
  bosses 
  of 
  the 
  9th 
  abdominal 
  segment, 
  each 
  side 
  

   with 
  about 
  36 
  hooks, 
  and 
  a 
  posterior 
  portion 
  confined 
  to 
  the 
  ventral 
  side 
  

   of 
  the 
  cremastral 
  spine, 
  each 
  side 
  with 
  about 
  60 
  or 
  70 
  hooks. 
  The 
  

   hooks 
  are 
  about 
  0-2mm. 
  long, 
  and 
  have 
  a 
  slightly 
  different 
  ending 
  to 
  

   those 
  of 
  A. 
  cosmodactyla 
  . 
  It 
  is, 
  as 
  if, 
  before 
  the 
  hook 
  of 
  A. 
  cosmodactyla 
  

   was 
  quite 
  finished, 
  a 
  further, 
  half 
  -turn 
  was 
  given 
  to 
  the 
  end. 
  The 
  eye- 
  

   piece 
  carries 
  two 
  hairs, 
  and 
  is 
  attached 
  to 
  the 
  dorsal 
  headpiece, 
  which 
  

   is 
  itself 
  indeterminable, 
  except 
  that 
  it 
  sometimes 
  carries 
  two 
  (nearly 
  

   always 
  one) 
  hairs, 
  but 
  is 
  otherwise 
  a 
  colourless 
  membrane, 
  indistinguish- 
  

   able 
  from 
  the 
  rest 
  of 
  the 
  inner 
  membrane, 
  connecting 
  the 
  eyepiece 
  to 
  

   the 
  prothorax. 
  The 
  spiracle-cover 
  on 
  the 
  mesothorax 
  is 
  a 
  short 
  arch, 
  

   with 
  a 
  hairy 
  or 
  spiculate 
  surface, 
  much 
  like 
  that 
  of 
  A, 
  cosmodactyla. 
  

   The 
  hindwings 
  end 
  at 
  posterior 
  border 
  of 
  the 
  2nd 
  abdominal 
  segment. 
  

   The 
  forewings 
  show 
  three 
  inner 
  veins, 
  and 
  the 
  cubital, 
  with 
  its 
  three 
  

   branches, 
  very 
  distinctly 
  ; 
  the 
  colouring 
  in 
  dark 
  pupae 
  is 
  enhanced 
  by 
  

   rows 
  of 
  slight 
  nodosities, 
  in 
  pale 
  ones 
  the 
  veins 
  forward 
  of 
  these 
  

   are 
  not 
  so 
  distinguishable. 
  The 
  face 
  carries 
  four 
  hairs 
  (two 
  each 
  side"), 
  

   the 
  clypeus 
  one 
  each 
  side, 
  and 
  the 
  labnun 
  two 
  on 
  each 
  side. 
  The 
  

   arrangement 
  of 
  appendages 
  seems 
  otherwise 
  much 
  the 
  same 
  as 
  in 
  

   A. 
  cosmodactyla 
  (Chapman, 
  June 
  27th, 
  1900. 
  

  

  Time 
  of 
  appearance. 
  -Single-brooded, 
  usually 
  occurring 
  from 
  end 
  

   of 
  June 
  until 
  early 
  August, 
  but 
  varying 
  a 
  little 
  m 
  different 
  years
