﻿372 
  BRITISH 
  LEPIDOPTEEA. 
  

  

  tively 
  slender 
  and 
  of 
  even 
  thickness, 
  with 
  a 
  large 
  head. 
  The 
  segments, 
  

   though 
  well-marked, 
  are 
  not 
  accentuated 
  ; 
  of 
  blunt-ended 
  appearance, 
  

   with 
  little 
  or 
  no 
  tapering 
  exhibited 
  ; 
  anal 
  claspers 
  large, 
  and 
  curiously 
  

   stretched 
  out 
  posteriorly 
  (after 
  the 
  manner 
  of 
  Liparid 
  larvae). 
  There 
  

   is 
  a 
  well-marked, 
  chitinous, 
  prothoracic 
  shield 
  ; 
  spiracles 
  not 
  raised, 
  and 
  

   rather 
  large, 
  with 
  black 
  rim 
  and 
  white 
  centre. 
  Each 
  segment 
  is, 
  

   apparently, 
  roughly 
  subdivided 
  into 
  two 
  large 
  sections 
  ; 
  this 
  is, 
  perhaps, 
  

   partly, 
  if 
  not 
  entirely, 
  due 
  to 
  the 
  tubercles 
  i 
  and 
  ii 
  being 
  somewhat 
  

   raised, 
  and 
  only 
  narrowly 
  separated, 
  which 
  gives 
  the 
  appearance 
  of 
  a 
  

   dorsal 
  subdivision. 
  Colour 
  dull 
  yellowish, 
  with 
  dark 
  median 
  stripe. 
  

   Head 
  : 
  Pale 
  yellowish, 
  slightly 
  mottled 
  at 
  sides 
  with 
  brown, 
  two 
  large 
  

   brown 
  blotches 
  round 
  ocelli, 
  and 
  two 
  dark 
  triangles 
  near 
  crown 
  of 
  the 
  

   same 
  colour. 
  Body 
  : 
  There 
  is 
  a 
  deep 
  brownish 
  depression, 
  or 
  shallow 
  

   pit, 
  on 
  either 
  side 
  of 
  the 
  scutellar 
  plate, 
  in 
  line 
  above 
  the 
  spiracles," 
  

   and 
  a 
  few 
  dark 
  (black) 
  spots 
  across 
  the 
  middle 
  line 
  of 
  scutelluni. 
  The 
  

   long 
  hairs 
  are 
  tapering 
  and 
  very 
  finely 
  thorned 
  ; 
  on 
  the 
  dorsal 
  area 
  they 
  

   have 
  an 
  oxhorn-like 
  curve, 
  that 
  is, 
  curve 
  outwards 
  laterally, 
  and 
  

   then 
  turn 
  in 
  again 
  towards 
  the 
  middle 
  line 
  at 
  the 
  tips. 
  They 
  are 
  blunt- 
  

   ended, 
  or 
  very 
  slightly 
  knobbed, 
  and 
  have 
  opaque 
  white 
  tips 
  like 
  those 
  of 
  

   the 
  larva 
  of 
  Capperia 
  heterodactyla. 
  The 
  larva 
  has, 
  also, 
  short, 
  scattered, 
  

   body-hairs 
  ; 
  these 
  appear 
  slightly 
  knobbed 
  at 
  the 
  tips, 
  and 
  are, 
  for 
  the 
  most 
  

   part, 
  white, 
  though 
  a 
  few 
  are 
  black. 
  The 
  tubercles 
  are 
  not 
  developed 
  

   into 
  definite 
  warts 
  ; 
  but 
  round 
  the 
  primary 
  setae 
  there 
  are 
  raised 
  skin- 
  

   areas, 
  and 
  some 
  of 
  the 
  previously 
  mentioned, 
  scattered, 
  secondary 
  hairs 
  

   approximate 
  to, 
  or 
  are 
  accidentally 
  near, 
  them 
  in 
  position 
  ; 
  a 
  fine 
  

   spicular 
  growth 
  covers 
  the 
  skin, 
  except 
  on 
  these 
  raised 
  areas 
  surround- 
  

   ing 
  the 
  primary 
  setae 
  ; 
  the 
  raised 
  skin-areas 
  are, 
  therefore, 
  shiny, 
  which 
  

   gives 
  them 
  a 
  chitinous 
  wart-like 
  appearance 
  that 
  is 
  not 
  altogether 
  

   warranted. 
  Tubercles 
  : 
  On 
  the 
  meso- 
  and 
  metathorax, 
  i 
  and 
  ii 
  are 
  

   combined 
  in 
  a 
  single 
  group, 
  on 
  the 
  anterior 
  of 
  the 
  two 
  subsegments; 
  

   there 
  is 
  also 
  a 
  large 
  secondary 
  seta 
  on 
  the 
  posterior 
  subdivision. 
  On 
  

   the 
  abdominal 
  segments, 
  i 
  and 
  ii 
  are 
  separate, 
  both 
  raised 
  and 
  wart- 
  

   like, 
  bearing 
  two 
  or 
  three 
  large, 
  and 
  several 
  smaller, 
  hairs 
  ; 
  iii 
  is 
  a 
  

   large, 
  somewhat 
  wart-like, 
  tubercle, 
  and 
  the 
  secondary 
  postspiracular 
  

   group 
  of 
  hairs 
  forms 
  a 
  wart 
  ; 
  this 
  is 
  present 
  on 
  the 
  meso- 
  and 
  meta- 
  

   thorax, 
  but 
  it 
  is 
  by 
  no 
  means 
  certain 
  that 
  the 
  group 
  on 
  these 
  segments 
  

   is 
  homologous 
  with 
  the 
  group 
  in 
  the 
  same 
  position 
  on 
  the 
  abdominal 
  

   segments. 
  There 
  is 
  a 
  somewhat 
  marked 
  flange 
  beneath 
  the 
  spiracles, 
  

   and, 
  on 
  this, 
  beneath 
  the 
  spiracle, 
  are 
  situated 
  iv 
  + 
  v, 
  forming 
  a 
  single 
  

   wart 
  ; 
  posterior 
  to 
  it, 
  also 
  on 
  the 
  flange, 
  is 
  another 
  small 
  group 
  of 
  

   hairs. 
  The 
  black, 
  secondary, 
  scattered 
  hairs 
  appear 
  curiously 
  irregular 
  

   in 
  position 
  ; 
  on 
  some 
  segments 
  they 
  occur 
  on 
  the 
  middle 
  line, 
  while, 
  

   on 
  other 
  segments, 
  the 
  hairs 
  in 
  this 
  position 
  are 
  white 
  ; 
  one 
  gets 
  the 
  

   idea 
  that 
  these 
  secondary 
  hairs 
  are 
  alike, 
  but, 
  by 
  some 
  accident, 
  some 
  

   become 
  black 
  ; 
  possibly, 
  however, 
  a 
  careful 
  comparison 
  would 
  show 
  a 
  

   regularity 
  in 
  this 
  apparent 
  disorder. 
  A 
  large, 
  chitinous, 
  anal 
  plate 
  is 
  

   present, 
  and 
  bears 
  three 
  longitudinal 
  rows 
  of 
  spots 
  (Bacot, 
  May 
  1st, 
  

   1904). 
  Length, 
  four 
  larvae 
  are 
  4mm.-5mm. 
  ; 
  thickness 
  less 
  than 
  1mm. 
  ; 
  

   two 
  others 
  are 
  rather 
  larger, 
  but 
  in 
  same 
  skin, 
  laid 
  up 
  for 
  moult 
  ; 
  these 
  

   two 
  looked 
  fatter 
  and 
  balder 
  than 
  either 
  of 
  those 
  that 
  are 
  smaller 
  but 
  

  

  * 
  This 
  is 
  probably 
  a 
  good 
  generic 
  or 
  tribal 
  character, 
  as 
  the 
  depression 
  can 
  be 
  

   found 
  on 
  all 
  the 
  allied 
  larvas 
  (Bacot).
