  extend 
  backwards, 
  separating 
  gradually 
  to 
  the 
  3rd 
  abdominal 
  segment, 
  

   but 
  are 
  not 
  very 
  evident 
  on 
  the 
  4th, 
  though 
  the 
  hairs, 
  etc., 
  of 
  tubercles 
  

   i 
  and 
  ii 
  give 
  a 
  superficial 
  appearance 
  of 
  their 
  continuing 
  to 
  the 
  tail. 
  

   Though 
  described 
  as 
  smooth, 
  it 
  has 
  these 
  flanges 
  or 
  ridges, 
  and 
  also 
  has 
  

   the 
  tubercles 
  well 
  expressed. 
  The 
  wings, 
  etc., 
  are 
  fixed 
  to 
  the 
  end 
  of 
  the 
  

   3rd 
  abdominal 
  segment, 
  and 
  the 
  points 
  of 
  the 
  wings 
  extend 
  a 
  little 
  

   further, 
  forming 
  a 
  base 
  to 
  the 
  penlike 
  3rd 
  legs, 
  which 
  extend 
  nearly 
  to 
  

   the 
  end 
  of 
  the 
  5th 
  abdominal 
  segment, 
  but 
  quite 
  free. 
  The 
  free 
  

   segments 
  are 
  the 
  4th, 
  5th, 
  6th 
  (7th 
  in 
  the 
  $ 
  ) 
  abdominals. 
  On 
  the 
  

   head 
  and 
  prothorax 
  several 
  hairs 
  are 
  found, 
  but 
  only 
  one 
  on 
  either 
  side, 
  

   definitely, 
  on 
  meso- 
  and 
  metathorax 
  ; 
  these 
  are 
  all 
  short, 
  curved, 
  

   clubbed 
  hairs, 
  clubbed 
  in 
  that 
  they 
  gradually 
  get 
  thicker 
  to 
  the 
  end. 
  

   On 
  the 
  1st 
  abdominal 
  segment, 
  similar 
  (but 
  smaller) 
  hairs 
  occur 
  on 
  

   the 
  extreme 
  anterior 
  (i) 
  and 
  posterior 
  (ii) 
  ends 
  of 
  the 
  subdorsal 
  ridges, 
  

   and 
  tubercle 
  iii 
  is 
  observed 
  laterally. 
  The 
  2nd 
  abdominal 
  segment 
  is 
  

   a 
  comparatively 
  long 
  segment 
  ; 
  the 
  ridge 
  is 
  divided 
  into 
  three 
  nearly 
  

   equal 
  portions 
  by 
  i, 
  just 
  inside 
  it, 
  and 
  ii, 
  on 
  it; 
  tubercle 
  iii 
  and 
  the 
  

   spiracle 
  being 
  well-spaced 
  laterally, 
  i.e., 
  not 
  at 
  all 
  crowded 
  together 
  or 
  

   with 
  others. 
  On 
  the 
  3rd 
  abdominal 
  segment, 
  the 
  ridge 
  extends 
  down 
  

   to 
  the 
  intersegmental 
  membrane, 
  which 
  occupies 
  the 
  posterior 
  fourth 
  

   of 
  the 
  segment 
  ; 
  tubercle 
  ii 
  is 
  at 
  the 
  extreme 
  end 
  of 
  the 
  ridge, 
  and 
  i, 
  

   in 
  front 
  of 
  it, 
  one-fourth 
  the 
  length 
  of 
  the 
  ridge 
  (segment 
  without 
  

   membrane) 
  in 
  front 
  of 
  it. 
  Their 
  structure 
  is 
  curious 
  ; 
  i 
  is 
  a 
  round 
  knob 
  

   with 
  a 
  hair 
  pointing 
  forward 
  from 
  its 
  anterior 
  face 
  ; 
  ii 
  has 
  the 
  hair 
  

   slightly 
  more 
  from 
  the 
  summit 
  and 
  pointing 
  backwards. 
  These 
  knobs 
  

   are 
  whitish, 
  but 
  too 
  small 
  to 
  have 
  any 
  colour 
  effect 
  on 
  the 
  pupa 
  unless 
  

   seen 
  through 
  a 
  lens 
  ; 
  iii 
  is 
  directed 
  forward. 
  The 
  transverse 
  wrinkling 
  or 
  

   ribbing 
  is 
  much 
  the 
  same 
  here 
  as 
  over 
  the 
  rest 
  of 
  the 
  pupa. 
  The 
  ribs 
  

   are 
  about 
  22 
  in 
  number, 
  and 
  are 
  fairly 
  pitted 
  along 
  their 
  ridges 
  ; 
  they 
  

   are 
  too 
  numerous 
  to 
  be 
  subsegments, 
  and 
  too 
  regular 
  and 
  continuous 
  to 
  

   be 
  regarded 
  as 
  the 
  anastomosing 
  wrinklings 
  occurring 
  on 
  many 
  pupa?. 
  

   They 
  may, 
  perhaps, 
  be 
  called 
  ribs, 
  without 
  any 
  theory 
  being 
  involved. 
  

   The 
  4th 
  abdominal 
  segment 
  has 
  20 
  ribs, 
  and 
  no 
  flange-ridge 
  ; 
  i, 
  ii, 
  and 
  iii 
  

   are 
  as 
  on 
  the 
  3rd 
  abdominal 
  segment 
  ; 
  the 
  large 
  white 
  beads 
  here, 
  

   carrying 
  the 
  hairs, 
  have, 
  very 
  definitely, 
  the 
  air 
  of 
  being 
  erect 
  and 
  

   symmetrical, 
  and 
  then 
  bent 
  or 
  rotated 
  forwards 
  (c.</., 
  i 
  and 
  iii) 
  or 
  

   backwards 
  {cjj., 
  ii) 
  ; 
  below 
  the 
  spiracle 
  are 
  two 
  hairs, 
  curved 
  and 
  

   clubbed 
  as 
  the 
  others, 
  but 
  without 
  raised 
  bases 
  ; 
  they 
  are 
  about 
  at 
  the 
  

   same 
  level, 
  the 
  anterior 
  one 
  below 
  the 
  spiracle, 
  and 
  with 
  two 
  ribs 
  

   between 
  them 
  ; 
  the 
  next 
  lower 
  is 
  four 
  ribs 
  behind 
  the 
  last, 
  is 
  strongly 
  

   directed 
  backwards, 
  and 
  has 
  a 
  raised 
  base 
  in 
  front 
  of 
  it. 
  The 
  5th 
  

   abdominal 
  segment 
  has 
  only 
  about 
  fifteen 
  ribs, 
  and 
  is 
  narrower 
  ; 
  the 
  

   tubercles, 
  etc., 
  are 
  the 
  same 
  ; 
  the 
  length 
  of 
  the 
  hairs 
  is 
  about 
  

   O08mm.-O09mm. 
  The 
  6th 
  and 
  7th 
  abdominal 
  segments 
  are 
  narrower. 
  

   but 
  the 
  same 
  otherwise, 
  still 
  with 
  fourteen 
  or 
  fifteen 
  ribs, 
  but 
  they 
  tend 
  a 
  

   little 
  to 
  anastomose. 
  On 
  the 
  8th 
  abdominal 
  segment, 
  tubercles 
  

   i 
  and 
  ii 
  have 
  a 
  ridge 
  between 
  them, 
  which 
  is 
  continued 
  down 
  the 
  ihh 
  

   and 
  10th 
  segments 
  as 
  a 
  support 
  to 
  the 
  cremaster, 
  but 
  seems 
  to 
  be 
  the 
  

   same 
  ridge 
  that 
  has 
  been 
  obsolete 
  from 
  the 
  lth 
  7th 
  abdominal 
  segments. 
  

   There 
  are 
  about 
  50-00 
  hooks 
  to 
  the 
  cremaster 
  under 
  the 
  8th 
  abdominal 
  

   segment, 
  but 
  they 
  are 
  much 
  more 
  numerous 
  on 
  the 
  10th 
  abdominal. 
  

   The 
  eyes 
  are 
  well 
  marked, 
  the 
  head 
  projects 
  forward 
  (w,, 
  wntrallv- 
  

   beyond 
  the 
  otherwise 
  1 
  straight 
  front 
  Line 
  ; 
  such 
  beak 
  as 
  there 
  is. 
  is
