﻿BUCKLERIA 
  PALUDUM.

  1st 
  abdominal 
  segment, 
  at 
  the 
  same 
  place, 
  is 
  a 
  similar 
  dot, 
  with 
  a 
  

   large, 
  spiracle-like, 
  oval 
  scar 
  behind 
  it, 
  and 
  of 
  a 
  dark 
  colour. 
  Otherwise, 
  

   there 
  are 
  no 
  hairs, 
  or 
  other 
  structures, 
  except 
  the 
  small 
  ochreous 
  

   spiracles 
  down 
  to 
  the 
  subspiracular 
  flange 
  ; 
  on 
  this, 
  are 
  two 
  minute 
  black 
  

   dots 
  (iv 
  + 
  v) 
  on 
  the 
  3rd 
  to 
  7th 
  abdominal 
  segments 
  ; 
  on 
  the 
  8th 
  abdominal 
  

   segment 
  there 
  are, 
  at 
  the 
  same 
  places, 
  two 
  short 
  (03mm.) 
  hairs. 
  These 
  are 
  

   repeated 
  on 
  the 
  9th, 
  except 
  that 
  the 
  1st 
  has 
  another 
  just 
  below 
  it. 
  On 
  the 
  

   10th 
  abdominal 
  segment, 
  one 
  similar 
  hair 
  seems. 
  distinct 
  from 
  the 
  cre- 
  

   mastral 
  hairs 
  in 
  which 
  it 
  is 
  very 
  close, 
  and 
  equally 
  short, 
  but 
  straight. 
  

   The 
  double 
  dots, 
  that 
  occur 
  on 
  the 
  3rd 
  abdominal 
  segment 
  to 
  the 
  

   7th 
  abdominal 
  segment, 
  are 
  forwards, 
  rather 
  close 
  together, 
  and 
  behind 
  

   the 
  spiracle. 
  More 
  ventral 
  on 
  the 
  5th, 
  6th, 
  and 
  7th, 
  abdominal 
  

   segments, 
  in 
  fact 
  ventral, 
  are, 
  on 
  either 
  side, 
  two 
  short 
  deflexed 
  hairs, 
  

   vii, 
  about 
  O'lmm. 
  and 
  0*2mm., 
  long; 
  on 
  a 
  pale 
  line, 
  between 
  these 
  and 
  

   the 
  subspiracular 
  flange, 
  is 
  a 
  small 
  black 
  dot, 
  hardly 
  a 
  hair, 
  vi 
  ; 
  a 
  

   similar 
  trace 
  of 
  iii 
  is 
  also 
  to 
  be 
  detected. 
  On 
  the 
  several 
  lines 
  of 
  these, 
  

   viz., 
  iii, 
  iv-fv, 
  vi, 
  and 
  vii, 
  there 
  are 
  longitudinal 
  pale 
  lines 
  that 
  look 
  

   sometimes 
  like 
  ridges, 
  largely 
  owing, 
  however, 
  to 
  coloration, 
  but 
  this 
  

   is 
  just 
  so 
  much 
  raised 
  on 
  the 
  subspiracular, 
  iv-j-v, 
  line, 
  that 
  I 
  have 
  

   ventured 
  to 
  call 
  it 
  a 
  subspiracular 
  flange. 
  The 
  appendages 
  reach 
  to 
  the 
  

   middle, 
  and 
  even 
  to 
  the 
  posterior 
  margin 
  (in 
  $ 
  s 
  ?), 
  of 
  the 
  5th 
  abdominal 
  

   segment, 
  and 
  look 
  attached 
  to 
  it, 
  but 
  are 
  free 
  beyond 
  the 
  3rd 
  

   abdominal 
  segment. 
  The 
  cremaster 
  consists 
  of 
  two 
  portions, 
  a 
  small 
  

   one 
  in 
  the 
  centre 
  of 
  the 
  9th 
  abdominal 
  segment, 
  and 
  a 
  larger 
  one 
  on 
  

   the 
  10th 
  abdominal 
  segment. 
  The 
  hairs, 
  together 
  with 
  the 
  dorsum 
  of 
  the 
  

   last 
  two 
  segments, 
  are 
  pinkish, 
  about 
  O'lmm. 
  long, 
  straight, 
  or 
  nearly 
  

   so, 
  with 
  a 
  small 
  knob 
  at 
  one 
  side 
  of 
  the 
  end, 
  as 
  though 
  a 
  hook 
  had 
  

   soldered 
  itself 
  to 
  the 
  shaft, 
  to 
  which 
  it 
  had 
  turned 
  round. 
  The 
  appendages 
  

   are 
  transparent 
  green, 
  with 
  rather 
  darker 
  olive 
  shading, 
  beside 
  the 
  

   wing-veins, 
  on 
  the 
  antennae 
  and 
  first 
  legs 
  (Chapman). 
  

  

  Variation 
  in 
  pupa. 
  — 
  The 
  variation 
  in 
  the 
  colour 
  of 
  the 
  pupa 
  is, 
  

   first, 
  in 
  the 
  amount 
  of 
  pink. 
  This 
  tends 
  to 
  fade 
  as 
  the 
  pupa 
  matures, 
  

   and 
  some 
  pupae 
  lose 
  it 
  altogether, 
  becoming 
  entirely 
  green. 
  One 
  pupa, 
  

   on 
  the 
  other 
  hand, 
  has 
  a 
  dorsal, 
  a 
  broad 
  subdorsal 
  (through 
  hump 
  and 
  

   hair-bases), 
  and 
  a 
  lower 
  (along 
  iii 
  ?), 
  rose-pink 
  line, 
  nearly 
  continuous 
  

   from 
  end 
  to 
  end 
  of 
  the 
  pupa, 
  and 
  is 
  consequently 
  a 
  handsome, 
  brilliant, 
  

   pupa. 
  The 
  depth 
  of 
  green 
  also 
  varies 
  a 
  little, 
  especially 
  on 
  the 
  wings 
  

   and 
  appendages, 
  which 
  may 
  be 
  pale 
  and 
  transparent, 
  or 
  a 
  deep 
  solid- 
  

   looking 
  green. 
  A 
  certain 
  olive-brown 
  tint 
  appears, 
  as 
  the 
  pupa 
  matures 
  

   for 
  emergence, 
  the 
  eyes, 
  wings, 
  &c, 
  becoming 
  black. 
  One 
  other 
  point 
  

   in 
  the 
  variability 
  of 
  the 
  pupa 
  has 
  regard 
  to 
  the 
  forward 
  hairs 
  (i) 
  of 
  the 
  

   abdominal 
  dorsum. 
  The 
  most 
  usual 
  form 
  is 
  perhaps 
  that 
  described, 
  

   with 
  this 
  hair 
  on 
  the 
  first 
  five 
  segments, 
  and 
  wanting 
  in 
  the 
  others 
  ; 
  

   it 
  does 
  not 
  often 
  show 
  any 
  length 
  on 
  5th 
  segment, 
  and 
  is 
  more 
  

   frequently 
  wanting 
  on 
  4th, 
  3rd, 
  or 
  even 
  2nd, 
  and 
  presumably 
  may 
  be 
  

   entirely 
  absent. 
  When 
  absent, 
  it 
  is, 
  however, 
  usually 
  represented 
  by 
  

   more 
  or 
  less 
  of 
  a 
  stump, 
  or 
  abbreviated 
  hair, 
  and 
  its 
  site, 
  when 
  absent, 
  

   is 
  marked 
  by 
  a 
  basal 
  circle 
  or 
  point. 
  It 
  is 
  unusual, 
  however, 
  as 
  

   happened 
  in 
  the 
  specimen 
  described, 
  for 
  the 
  hairs 
  present 
  to 
  be 
  well 
  

   developed 
  and 
  the 
  rest 
  to 
  be 
  absent, 
  i.e., 
  merely 
  a 
  basal 
  trace 
  present. 
  

   It 
  is 
  more 
  usual 
  for 
  there 
  to 
  be 
  one 
  or 
  two 
  intermediate, 
  abbreviated, 
  

   hairs, 
  as 
  for 
  example, 
  1st 
  and 
  2nd, 
  good 
  hairs, 
  3rd, 
  shortened 
  hair.
