  BRITISH 
  LEPIDOPTERA. 
  

  

  better 
  marked 
  on 
  the 
  thoracic 
  segments. 
  The 
  body 
  is 
  bright 
  green, 
  

   softened 
  somewhat 
  by 
  the 
  secondary 
  hair 
  growth; 
  a 
  broad 
  crimson 
  

   mediodorsal 
  band, 
  and 
  a 
  narrow, 
  somewhat 
  interrupted, 
  white 
  subdorsal 
  

   line. 
  Hairs, 
  and 
  the 
  bases 
  of 
  tubercles, 
  white, 
  but 
  some 
  of 
  the 
  secondaries 
  

   are 
  dark. 
  Head 
  smooth 
  and 
  glassy 
  in 
  appearance, 
  very 
  pale 
  brown, 
  with 
  

   black 
  ocelli, 
  and 
  a 
  black 
  spot 
  on 
  either 
  lobe 
  near 
  the 
  crown 
  ; 
  there 
  is 
  

   also 
  a 
  slight 
  mottling 
  of 
  pale 
  brown 
  on 
  the 
  cheeks. 
  Body: 
  the 
  pro- 
  

   thoracic 
  scutellum 
  fairly 
  distinct, 
  but 
  the 
  anal 
  plate 
  less 
  so, 
  although 
  

   both 
  are 
  more 
  chitinous 
  in 
  appearance 
  than 
  the 
  general 
  skin-surface. 
  

   The 
  scutellum 
  bears 
  the 
  two, 
  dark-coloured, 
  depressed, 
  spots 
  as 
  in 
  5. 
  ptero- 
  

   dactyla, 
  etc. 
  The 
  spiracles 
  are 
  large, 
  but 
  not 
  highly 
  raised, 
  their 
  dark 
  

   brown 
  chitinous 
  rims 
  showing 
  up 
  in 
  marked 
  contrast 
  against 
  the 
  pale 
  

   skin 
  ; 
  as 
  usual, 
  those 
  on 
  the 
  pro 
  thorax 
  and 
  the 
  8th 
  and 
  1st 
  abdominal 
  seg- 
  

   ments 
  are 
  larger 
  than 
  the 
  rest, 
  the 
  two 
  former 
  considerably, 
  and 
  the 
  latter 
  

   slightly 
  so, 
  but 
  there 
  is 
  no 
  marked 
  difference 
  in 
  shape. 
  The 
  spicular 
  coat 
  

   is 
  a 
  marked 
  feature, 
  being 
  both 
  coarse 
  and 
  dark-coloured 
  as 
  well 
  ; 
  one 
  

   hardly 
  knows 
  whether 
  to 
  call 
  the 
  spicules 
  buttons, 
  or 
  spines, 
  but, 
  perhaps, 
  

   the 
  latter 
  is 
  more 
  correct, 
  as 
  they 
  seem 
  to 
  be 
  low, 
  broad-based, 
  pyramidal 
  

   spines. 
  A 
  strong 
  development 
  of 
  secondary 
  hairs 
  is 
  fairly 
  evenly 
  

   scattered 
  over 
  the 
  general 
  skin-surface 
  ; 
  these 
  are 
  short 
  and 
  bristle-like, 
  

   slightly 
  knobbed 
  at 
  the 
  top 
  ; 
  some 
  are 
  dark, 
  but 
  they 
  are 
  mostly 
  pale 
  ; 
  

   these 
  are 
  much 
  more 
  numerous 
  than 
  in 
  Stenoptilia 
  pterodactyla, 
  and 
  

   remind 
  one, 
  when 
  viewed 
  under 
  a 
  hand-lens, 
  rather 
  of 
  the 
  coats 
  of 
  

   Gillmeri-a 
  pallidactyla 
  and 
  Platyptilia 
  gonodactyla, 
  but 
  a 
  lin. 
  objective 
  

   shows 
  up 
  the 
  difference 
  at 
  once, 
  the 
  hairs, 
  in 
  comparsion 
  with 
  those 
  

   of 
  G. 
  pallidactyla, 
  in 
  its 
  last 
  skin, 
  being 
  much 
  sparser, 
  but 
  individually 
  

   larger, 
  and 
  knobbed 
  at 
  the 
  tip, 
  those 
  of 
  G. 
  pallidactyla 
  forming 
  a 
  finer, 
  

   more 
  even, 
  and 
  much 
  thicker, 
  growth. 
  Tubercles 
  are 
  not 
  primitive, 
  

   yet 
  can 
  hardly 
  be 
  called 
  warts 
  ; 
  the 
  hairs 
  are 
  white 
  and 
  have 
  white 
  

   bases, 
  and 
  they 
  appear 
  fairly 
  smooth, 
  but 
  are, 
  I 
  think, 
  very 
  finely 
  

   thorned, 
  and 
  slightly 
  knobbed 
  at 
  the 
  tips. 
  As 
  a 
  rule, 
  there 
  is 
  one 
  large 
  

   primary 
  hair 
  and 
  a 
  medium 
  secondary, 
  and 
  possibly 
  one 
  or 
  two 
  of 
  the 
  

   small 
  secondary 
  hairs, 
  similar 
  to 
  those 
  scattered 
  over 
  the 
  skin-surface, 
  

   associated 
  in 
  each 
  tubercular 
  group 
  ; 
  though, 
  wmether 
  the 
  proximity 
  of 
  

   the 
  small 
  skin-surface 
  secondaries 
  is 
  a 
  matter 
  of 
  accident, 
  or 
  really 
  an 
  

   association, 
  is 
  not 
  clear, 
  but 
  I 
  am 
  inclined 
  to 
  think 
  the 
  latter, 
  as 
  these 
  

   small 
  hairs, 
  when 
  so 
  placed, 
  seem 
  to 
  my 
  eyes 
  to 
  be 
  slightly 
  larger 
  than 
  

   those 
  elsewhere. 
  On 
  the 
  meso- 
  and 
  metathorax, 
  i 
  and 
  ii 
  are 
  united 
  at 
  

   their 
  bases, 
  the 
  inner 
  and 
  forward 
  hair, 
  probably 
  i, 
  being 
  the 
  larger; 
  

   iii 
  and 
  iv 
  form 
  a 
  similar 
  pair 
  ; 
  v 
  and 
  the 
  subprimary 
  vi 
  form 
  another 
  

   pair; 
  beneath 
  them, 
  and 
  the 
  posterior 
  subprimary, 
  is 
  a 
  single 
  hair 
  slightly 
  

   above 
  the 
  level 
  of 
  the 
  last-named 
  pair 
  ; 
  vii 
  is 
  a 
  two-haired 
  pair 
  at 
  the 
  

   base 
  of 
  legs. 
  [Only 
  the 
  larger 
  hairs 
  are 
  noticed 
  in 
  the 
  above 
  remarks.] 
  

   On 
  the 
  abdominal 
  segments 
  i 
  and 
  ii 
  are 
  set 
  trapezoiclally, 
  their 
  bases 
  

   well 
  apart, 
  both 
  having, 
  usually 
  in 
  close 
  proximity 
  to 
  their 
  bases, 
  a 
  

   hair 
  rather 
  larger 
  than 
  the 
  normal 
  secondaries, 
  as 
  well 
  as 
  two 
  or 
  three 
  

   of 
  normal, 
  or 
  only 
  very 
  slightly 
  above 
  normal, 
  size, 
  these 
  latter 
  

   are 
  not 
  infrequently 
  dark 
  ; 
  iii 
  is 
  also 
  a 
  large 
  hair 
  with 
  another 
  much 
  

   smaller 
  hair 
  adjoining 
  its 
  base, 
  and 
  one 
  or 
  more 
  of 
  the 
  normal 
  or 
  nearly 
  

   normal 
  secondaries 
  ; 
  iv 
  and 
  v 
  conjoined 
  at 
  base, 
  directly 
  below 
  spiracle, 
  

   each 
  with 
  long 
  hair. 
  The 
  upper 
  post-spiracular, 
  accessory 
  group 
  is 
  

   represented 
  by 
  a 
  single 
  medium-sized 
  hair 
  as 
  in 
  S. 
  pterodactyla. 
  This 
  

   hair 
  is 
  not 
  nearly 
  so 
  large 
  as 
  the 
  primary 
  hairs; 
  there 
  is, 
  however, 
  

   no 
  trace 
  of 
  the 
  lower 
  subprimary 
  postspiracular 
  group 
  of 
  hairs 
  which 
  is
