  affixed, 
  the 
  difference, 
  on 
  close 
  examination, 
  is 
  not 
  great, 
  but 
  is 
  enough 
  

   to 
  strike 
  the 
  eye. 
  [I 
  have 
  only 
  one 
  pupa, 
  and 
  that 
  one 
  was 
  much 
  

   disturbed 
  in 
  its 
  last 
  larval 
  instar 
  and 
  had 
  no 
  silk 
  to 
  which 
  to 
  attach 
  

   itself, 
  so 
  that 
  the 
  difference 
  may 
  be 
  due 
  to 
  the 
  abnormal 
  conditions, 
  

   but 
  there 
  is 
  no 
  appearance 
  of 
  deformity.] 
  To 
  complete 
  the 
  account 
  of 
  

   these 
  terminal 
  segments, 
  the 
  length 
  along 
  the 
  dorsal 
  line 
  of 
  the 
  8th 
  

   abdominal 
  segment 
  is 
  04mm., 
  and 
  of 
  the 
  9th 
  and 
  10th, 
  to 
  apex 
  of 
  

   cremastrai 
  pen, 
  is 
  0*8mm., 
  together 
  l*2mm. 
  In 
  Gillmeria 
  pallidactyla 
  

   (bertrami) 
  the 
  three 
  segments 
  are 
  l'7mm., 
  of 
  which 
  the 
  8th 
  takes 
  about 
  

   0'45mm., 
  and 
  the 
  9th 
  and 
  10th, 
  l-25mm. 
  As 
  the 
  dorsal 
  line 
  is 
  fairly 
  

   straight, 
  the 
  result 
  is 
  that 
  the 
  ventral 
  aspect 
  of 
  the 
  9th 
  is 
  terminal 
  

   rather 
  than 
  ventral. 
  The 
  cremastrai 
  hooks 
  are 
  a 
  set 
  of 
  ten 
  forward, 
  

   apparently 
  arising 
  from 
  the 
  two 
  round 
  ventral 
  eminences 
  of 
  the 
  9th 
  

   segment, 
  and 
  a 
  posterior 
  set 
  rising 
  round 
  the 
  margin 
  of 
  the 
  cremastrai 
  

   spine, 
  eight 
  or 
  ten 
  near 
  the 
  apex 
  (of 
  which 
  one 
  or 
  two 
  are 
  on 
  the 
  

   dorsum), 
  and 
  then, 
  after 
  a 
  vacant 
  space, 
  some 
  thirteen 
  or 
  fourteen 
  along 
  

   the 
  margin 
  quite 
  up 
  to 
  the 
  base; 
  all 
  are 
  directed 
  in 
  the 
  plane 
  of 
  the 
  

   cremastrai 
  pen, 
  i.e., 
  except 
  the 
  terminal 
  one, 
  laterally, 
  rather 
  than 
  

   ventrally; 
  they 
  are 
  brown 
  straight 
  bristles, 
  with 
  one 
  complete 
  close 
  

   circular 
  coil 
  at 
  the 
  end, 
  so 
  close 
  that 
  the 
  central 
  opening 
  of 
  the 
  circle 
  

   is 
  less 
  than 
  the 
  thickness 
  of 
  the 
  bristle 
  ; 
  they 
  are 
  about 
  0-12mm. 
  

   long. 
  The 
  anal 
  scar 
  is 
  deep, 
  between 
  two 
  large 
  rounded 
  and 
  very 
  

   wrinkled 
  eminences. 
  The 
  eminences 
  of 
  the 
  9th 
  abdominal 
  segment 
  

   have 
  been 
  referred 
  to. 
  The 
  pupa 
  is 
  a 
  male. 
  The 
  cremastrai 
  spine 
  

   has 
  a 
  lofty 
  ridge 
  down 
  each 
  side 
  of 
  its 
  dorsal 
  aspect, 
  on 
  each 
  

   are 
  two 
  minute 
  hairs 
  (0*02mm. 
  or 
  0-03mm. 
  in 
  length) 
  which 
  probably 
  

   represent 
  tubercles 
  li 
  of 
  the 
  9th 
  and 
  10th 
  abdominal 
  segments 
  respectively. 
  

   The 
  length 
  of 
  the 
  pupa 
  is 
  just 
  10-0mm.; 
  seen 
  laterally 
  it 
  is 
  just 
  2mm. 
  

   at 
  the 
  2nd 
  abdominal 
  segment, 
  in 
  antero-posterior 
  diameter; 
  forwards 
  

   it 
  gets 
  rather 
  narrower, 
  notwithstanding 
  the 
  dorsal 
  crests 
  (ridges 
  

   or 
  flanges) 
  on 
  the 
  mesothorax. 
  It 
  tapers 
  to 
  about 
  l-3mm. 
  at 
  the 
  7 
  th 
  

   abdominal 
  segment, 
  the 
  8th 
  is 
  about 
  1mm. 
  in 
  diameter. 
  The 
  nose- 
  

   horn 
  is 
  long 
  and 
  sharp, 
  about 
  0-6mm. 
  long 
  and 
  about 
  0-lmm. 
  wide 
  at 
  

   base, 
  and, 
  with 
  the 
  whole 
  head, 
  is 
  much 
  wrinkled, 
  chiefly 
  transversely, 
  

   and 
  half-way 
  along 
  has 
  a 
  small 
  knob 
  on 
  each 
  side 
  carrying 
  a 
  hair, 
  with 
  

   a 
  smaller 
  knob 
  nearer 
  the 
  sharp 
  apex. 
  The 
  mandibles 
  are 
  well 
  marked 
  

   and 
  much 
  wrinkled, 
  they 
  meet 
  in 
  the 
  middle 
  line 
  for 
  about 
  O'lmm., 
  

   and 
  so 
  the 
  labrum 
  is 
  only 
  seen 
  above 
  them; 
  between 
  them 
  and 
  the 
  two 
  

   portions 
  of 
  the 
  maxilhe 
  is 
  a 
  small 
  diamond- 
  shaped 
  piece 
  of 
  labium. 
  The 
  

   maxilla? 
  disappear 
  under 
  the 
  first 
  legs 
  after 
  about 
  3mm., 
  and 
  remain 
  

   so 
  for 
  rOmm. 
  and 
  reappear 
  for 
  a 
  final 
  1-Onim. 
  between 
  the 
  wing-tips, 
  

   the 
  first 
  legs 
  ending 
  just 
  after 
  they 
  reappear. 
  The 
  bundle 
  of 
  free 
  

   appendages 
  over 
  the 
  4th 
  abdominal 
  segment 
  does 
  not 
  quite 
  reach 
  its 
  

   posterior 
  border. 
  Its 
  tip 
  consists 
  of 
  the 
  second 
  and 
  third 
  tarsi 
  ; 
  the 
  

   maxilhe 
  nearly 
  reach 
  the 
  tip, 
  the 
  sharply 
  -produced 
  wing 
  apices 
  are 
  a 
  

   little 
  shorter, 
  and 
  the 
  first 
  legs 
  barely 
  reach 
  into 
  the 
  bundle 
  ; 
  the 
  first 
  but 
  

   not 
  the 
  second 
  legs 
  reach 
  up 
  to 
  the 
  eyes. 
  The 
  antenna 
  extend 
  to 
  a 
  little 
  

   below 
  where 
  the 
  maxilla* 
  disappear, 
  all 
  these 
  appendages 
  are 
  wrinkled, 
  

   chiefly 
  transversely, 
  but 
  the 
  more 
  basal 
  portion 
  of 
  the 
  antennae 
  are 
  quite 
  

   roughly 
  and 
  goutily 
  lumpy. 
  The 
  wings 
  show 
  the 
  vena 
  lion 
  as 
  ridges, 
  but 
  

   without 
  colouring; 
  the 
  hindwingsend 
  just 
  past 
  the 
  spiracle 
  of 
  the 
  2nd 
  

   (not 
  the 
  3rd) 
  abdominal, 
  and 
  have 
  a 
  quasi-suture 
  marking 
  them 
  from 
  

   themetathorax. 
  There 
  is 
  a 
  minute 
  but 
  distinct 
  dorsal 
  head-piece, 
  which, 
  

   on 
  dehiscence, 
  remains 
  attached 
  to 
  tin* 
  prot 
  borax 
  and 
  also 
  keeps 
  the 
  eye-
