  represented 
  in 
  Stenoptilia 
  pterodactyla. 
  Below 
  the 
  pale, 
  whitish, 
  

   lateral 
  line, 
  is 
  vi, 
  with 
  a 
  single 
  large 
  hair, 
  and 
  two 
  rather 
  smaller 
  ones 
  

   at, 
  or 
  close 
  to, 
  the 
  margin, 
  represent 
  vii 
  ; 
  there 
  is 
  a 
  slight 
  tendency 
  to 
  

   develop 
  a 
  lateral 
  flange. 
  The 
  true 
  legs 
  are 
  dark 
  ; 
  the 
  prolegs 
  tall 
  as 
  

   usual, 
  and 
  pale-coloured

  Final 
  instar 
  (fullgrown) 
  : 
  

   A 
  deep 
  summer 
  grass-green, 
  as 
  compared 
  with 
  the 
  delicate, 
  light, 
  

   spring 
  green 
  of 
  Leioptilus 
  tephradactyla, 
  with 
  a 
  broad, 
  brown-red, 
  

   dorsal 
  stripe, 
  and 
  the 
  same 
  colour 
  tints 
  the 
  rest 
  of 
  the 
  larva, 
  giving 
  the 
  

   green 
  its 
  dark 
  tint, 
  when, 
  on 
  a 
  general 
  view, 
  one 
  calls 
  it 
  green 
  with 
  

   red 
  dorsal 
  line 
  ; 
  really 
  the 
  colour 
  is 
  not 
  green, 
  but 
  red 
  ; 
  but, 
  except 
  

   dorsally, 
  it 
  is 
  so 
  thinly 
  spread, 
  that 
  the 
  green 
  contents 
  show 
  through. 
  

   There 
  are 
  two 
  very 
  distinct 
  subsegments; 
  tubercles 
  i 
  and 
  iii 
  with 
  single 
  

   long 
  white 
  hairs 
  (no 
  other 
  tubercles) 
  on 
  the 
  1st 
  subsegment, 
  and 
  ii 
  on 
  

   the 
  2nd 
  subsegment 
  ; 
  outside 
  i 
  and 
  ii 
  is 
  an 
  irregular, 
  almost 
  green, 
  

   line 
  ; 
  above 
  i 
  and 
  ii 
  are 
  short 
  secondary 
  hairs, 
  regularly 
  scattered, 
  i.e., 
  

   about 
  equally 
  spaced, 
  but 
  not 
  in 
  any 
  symmetrical 
  position 
  ; 
  of 
  these, 
  

   about 
  10 
  or 
  12 
  are 
  black, 
  25 
  to 
  30 
  white 
  ; 
  they 
  are 
  placed 
  similarly 
  

   over 
  the 
  rest 
  of 
  the 
  larva. 
  Immediately 
  below 
  the 
  spiracle 
  is 
  a 
  tubercle 
  

   with 
  two 
  long 
  hairs 
  (iv 
  and 
  v), 
  one 
  forward, 
  one 
  backward 
  ; 
  lower 
  

   down, 
  a 
  tubercle 
  with 
  a 
  solitary 
  hair, 
  and 
  yet 
  another 
  nearly 
  at 
  base 
  of 
  

   proleg. 
  The 
  prolegs 
  are 
  on 
  long 
  props. 
  The 
  underside 
  of 
  the 
  larva 
  is 
  

   more 
  definitely 
  green; 
  the 
  head 
  green, 
  marbled 
  with 
  brown 
  (Chapman). 
  

   Fullgrown 
  : 
  About 
  5 
  lines 
  in 
  length, 
  of 
  moderate 
  proportion, 
  neither 
  

   stout 
  nor 
  slender, 
  tolerably 
  cylindrical, 
  tapering 
  a 
  little 
  posteriorly; 
  

   the 
  head 
  rounded 
  and 
  rather 
  smaller 
  than 
  the 
  second 
  segment, 
  of 
  a 
  very 
  

   pale 
  colour 
  and 
  shining 
  ; 
  the 
  body 
  is 
  very 
  pale 
  olive-yellow, 
  with 
  a 
  

   conspicuous 
  brown 
  dorsal 
  line 
  attenuated 
  at 
  each 
  end, 
  and 
  with 
  two 
  

   faint 
  lines 
  along 
  the 
  side 
  a 
  little 
  deeper 
  than 
  the 
  tint 
  of 
  the 
  ground 
  

   colour 
  ; 
  on 
  the 
  lowest 
  line 
  are 
  the 
  black 
  spiracles, 
  each 
  on 
  a 
  slight 
  

   swelling; 
  the 
  tubercular 
  warts 
  are 
  of 
  the 
  pale 
  ground 
  colour 
  and 
  furnished 
  

   with 
  rather 
  long 
  curved 
  whitish 
  hairs; 
  the 
  head 
  and 
  other 
  parts 
  of 
  the 
  

   body 
  emit 
  short 
  hairs 
  (Buckler). 
  Larva 
  spindle-shaped, 
  verdigris- 
  

   green 
  ; 
  a 
  broad, 
  dull, 
  red, 
  dorsal 
  line, 
  margined 
  on 
  both 
  sides 
  with 
  

   whitish-green, 
  as 
  far 
  as 
  the 
  usual 
  position 
  of 
  the 
  subdorsal 
  line.
