  same 
  in 
  all 
  cases, 
  but, 
  in 
  this 
  species, 
  the 
  ribs 
  appear 
  to 
  have 
  flat 
  tops, 
  

   with 
  sharp 
  margins 
  where 
  they 
  meet 
  the 
  slopes 
  into 
  the 
  valleys. 
  The 
  

   anterior 
  margins 
  of 
  the 
  segments, 
  especially 
  ventrally, 
  show 
  sharp 
  skin- 
  

   points, 
  but 
  these 
  seem 
  less 
  widely 
  distributed 
  than 
  in, 
  say, 
  P. 
  isodactylus. 
  

   In 
  other 
  respects 
  the 
  pupa 
  is 
  too 
  like 
  that 
  species 
  to 
  be 
  worth 
  describing 
  

   separately 
  (Chapman, 
  May 
  29th, 
  1904). 
  

  

  Variation 
  in 
  pupa 
  of 
  Gillmeria 
  ochrodactyla. 
  — 
  The 
  pupa 
  is 
  -5in. 
  

   in 
  length, 
  slender, 
  with 
  a 
  longish 
  beak 
  in 
  front, 
  projecting 
  at 
  a 
  slight 
  

   angle 
  downwards 
  from 
  the 
  head, 
  pointed 
  at 
  the 
  tail 
  ; 
  the 
  wing-covers 
  

   of 
  moderate 
  length, 
  well-developed, 
  and 
  the 
  ends 
  of 
  the 
  leg-cases 
  

   projecting 
  free 
  from 
  the 
  abdomen 
  ; 
  its 
  figure, 
  in 
  repose, 
  is 
  a 
  little 
  curved, 
  

   so 
  as 
  to 
  be 
  concave, 
  on 
  the 
  back. 
  In 
  colour 
  it 
  varies, 
  some 
  examples 
  

   being 
  very 
  pale 
  greenish, 
  others 
  light 
  pinkish-grey, 
  while 
  others 
  again 
  

   are 
  dark 
  reddish-grey 
  ; 
  in 
  the 
  pale 
  green 
  variety, 
  the 
  characteristic 
  

   darker 
  markings, 
  though 
  partially 
  present 
  in 
  deeper 
  tints 
  of 
  greenish, 
  

   are 
  more 
  tenderly 
  rendered 
  than 
  in 
  some 
  of 
  the 
  greyish 
  varieties, 
  

   which 
  are 
  marked 
  as 
  follows 
  : 
  the 
  beak 
  is 
  white 
  above, 
  and 
  black 
  

   at 
  the 
  sides 
  ; 
  on 
  the 
  thorax 
  a 
  blackish-brown 
  dorsal 
  stripe 
  widens 
  and 
  

   then 
  narrows, 
  and 
  from 
  thence 
  passes 
  down 
  of 
  uniform 
  width 
  to 
  the 
  

   tail 
  ; 
  on 
  the 
  thorax, 
  it 
  is 
  margined 
  with 
  a 
  line 
  of 
  white 
  ; 
  the 
  subdorsal 
  

   line 
  is 
  blackish-brown 
  and 
  rather 
  interrupted 
  ; 
  between 
  this 
  and 
  the 
  

   dorsal 
  stripe, 
  on 
  each 
  segment, 
  are 
  double 
  dark 
  brown 
  streaks 
  a 
  little 
  

   divergent 
  ; 
  these 
  are 
  strongly 
  marked 
  on 
  the 
  anterior 
  segments, 
  but 
  

   more 
  faintly, 
  by 
  degrees, 
  on 
  the 
  hinder 
  ones 
  ; 
  at 
  an 
  interval 
  below 
  the 
  

   subdorsal 
  another 
  brown 
  line 
  occurs, 
  rather 
  interrupted 
  ; 
  the 
  lateral 
  line 
  

   is 
  white, 
  bordered 
  beneath 
  by 
  a 
  stripe 
  of 
  black 
  ; 
  the 
  ventral 
  surface 
  of 
  

   each 
  segment 
  has 
  a 
  broad, 
  central, 
  somewhat 
  squarish, 
  mark 
  of 
  light 
  

   brownish-grey, 
  and 
  a 
  fine 
  subventral 
  line 
  of 
  similar 
  tint, 
  much 
  

   interrupted 
  ; 
  the 
  wing-covers 
  brownish-grey 
  with 
  whitish 
  rays 
  

   (Buckler). 
  Whitish-green, 
  streaked 
  dorsally 
  and 
  laterally 
  with 
  

   olivaceous-brown 
  ; 
  thorax 
  humped 
  ; 
  from 
  the 
  head 
  is 
  a 
  beak-like 
  

   projection, 
  which 
  is 
  whitish 
  in 
  front 
  and 
  blackish 
  at 
  the 
  sides 
  ; 
  the 
  

   lower 
  portion 
  of 
  the 
  antenna-cases 
  are 
  detached 
  from 
  the 
  abdomen 
  

   (South). 
  Buckler 
  figured 
  (Larvae, 
  etc., 
  pi. 
  clxiii., 
  figs. 
  Sb-Sc), 
  on 
  

   June 
  17th, 
  1875, 
  two 
  forms 
  of 
  the 
  pupa 
  of 
  this 
  species, 
  one 
  bright 
  

   green, 
  the 
  other 
  grey. 
  

  

  Comparison 
  of 
  pup^: 
  of 
  Gillmeria 
  ochrodactyla 
  and 
  G. 
  palli- 
  

   dactyla. 
  — 
  The 
  difference 
  between 
  the 
  pupae 
  of 
  these 
  species 
  is 
  very 
  diffi- 
  

   cult 
  to 
  define. 
  In 
  the 
  specimens 
  compared— 
  four 
  of 
  G. 
  pallidactyla 
  and 
  

   ten 
  of 
  G. 
  ochrodactyla 
  — 
  one 
  might 
  define 
  that 
  of 
  pallidactyla 
  as 
  a 
  nearly 
  

   white 
  pupa, 
  with 
  faint 
  markings, 
  and 
  that 
  of 
  ochrodactyla 
  as 
  a 
  pupa, 
  dark 
  

   from 
  the 
  intensity 
  of 
  the 
  markings. 
  In 
  the 
  latter, 
  these 
  markings 
  

   differ 
  from 
  those 
  of 
  Platyptilia 
  gonodactyla 
  and 
  P. 
  isodactylus 
  in 
  being 
  

   very 
  clear 
  and 
  distinct, 
  with 
  sharp 
  margins, 
  not 
  fading 
  away 
  into 
  the 
  

   pale 
  areas. 
  This 
  difference 
  between 
  G. 
  ochrodactyla 
  and 
  G. 
  pallidactyla, 
  

   however, 
  is 
  probably 
  true 
  only 
  of 
  my 
  specimens, 
  as 
  I 
  have 
  one 
  ochro- 
  

   dactyla 
  that 
  is 
  very 
  nearly 
  as 
  pale 
  as 
  pallidactyla, 
  and, 
  in 
  this 
  pale 
  one, 
  

   I 
  cannot 
  so 
  easily 
  differentiate 
  the 
  markings 
  from 
  those 
  of 
  pallidactyla. 
  

   I 
  imagine 
  that, 
  in 
  a 
  longer 
  series, 
  there 
  would 
  be 
  much 
  overlapping. 
  

   To 
  return 
  to 
  the 
  markings 
  of 
  ochrodactyla, 
  they 
  consist 
  of 
  a 
  dark 
  

   dorsal 
  line 
  or 
  band, 
  and 
  three 
  more 
  between 
  it 
  and 
  the 
  spiracle 
  ; 
  these 
  

   are 
  fairly 
  continuous, 
  and 
  differ 
  in 
  darker 
  and 
  lighter 
  specimens 
  in 
  

   width 
  and 
  intensity, 
  but 
  always 
  have 
  a 
  fairly 
  defined 
  margin.
