  Usually, 
  however, 
  they 
  are 
  much 
  earlier 
  — 
  young 
  larvae 
  

   found 
  at 
  the 
  end 
  of 
  April, 
  in 
  north 
  Wales, 
  were 
  nearly 
  fullfed 
  by 
  May 
  

   19th, 
  1867; 
  whilst 
  on 
  March 
  25th, 
  1867, 
  and 
  following 
  days, 
  in 
  the 
  

   Llanferras 
  district, 
  young 
  hybernating 
  larvae 
  were 
  just 
  beginning 
  to 
  

   feed 
  (Gregson) 
  ; 
  larvae 
  were 
  searched 
  for 
  on 
  June 
  5th, 
  1904, 
  but 
  were 
  

   then 
  nearly 
  over, 
  and 
  only 
  three 
  obtained, 
  although 
  many 
  stems 
  showed 
  

   w 
  7 
  here 
  they 
  had 
  been 
  attacked 
  ; 
  the 
  larvae 
  had 
  mostly 
  fed 
  up 
  and 
  

   apparently 
  left 
  the 
  plant 
  (Atmore).

   colour, 
  with 
  a 
  double 
  series 
  of 
  white 
  dorsal 
  patches 
  ; 
  the 
  skin 
  much 
  

   wrinkled, 
  lateral 
  flange 
  already 
  present. 
  Head 
  polished 
  black 
  ; 
  

   thoracic 
  segments 
  large 
  ; 
  true 
  legs 
  strong, 
  prolegs 
  weak, 
  but 
  tall, 
  as 
  in 
  

   adult 
  larva; 
  prothoracic 
  plate 
  of 
  a 
  medium 
  brown 
  tint. 
  On 
  the 
  meso- 
  

   and 
  metathorax, 
  as 
  well 
  as 
  abdominal 
  segments, 
  i-f 
  ii 
  are 
  on 
  the 
  same 
  

   plate. 
  On 
  the 
  meso- 
  and 
  metathorax, 
  iii 
  is 
  large 
  and 
  iv 
  small 
  (the 
  

   former 
  well 
  in 
  front 
  of 
  the 
  latter); 
  v, 
  placed 
  below 
  them, 
  carries 
  a 
  

   strong 
  hair. 
  On 
  the 
  abdominal 
  segments, 
  tubercle 
  iii 
  is 
  situated 
  in 
  

   its 
  usual 
  position, 
  iv 
  and 
  v, 
  each 
  carrying 
  a 
  hair, 
  forming 
  a 
  twin 
  pair 
  

   directly 
  below 
  the 
  spiracle, 
  v 
  the 
  smaller. 
  The 
  skin 
  appears 
  quite 
  

   smooth 
  and 
  shiny 
  under 
  a 
  ^-inch 
  objective, 
  showing 
  no 
  trace 
  of 
  spicules. 
  

   The 
  hairs 
  are 
  comparatively 
  short, 
  smooth, 
  and 
  tapering, 
  with 
  slightly 
  

   knobbed 
  ends, 
  but 
  not 
  thorned 
  (Bacot, 
  July 
  10th,

  Second 
  

   instar

  3- 
  5mm.

  Head 
  black. 
  The 
  body 
  with 
  a 
  coat 
  of 
  coarse 
  

   spicules 
  ; 
  secondary 
  hairs 
  restricted 
  to 
  the 
  tubercular 
  areas, 
  w 
  T 
  ith 
  two 
  

   exceptions, 
  and 
  these 
  are 
  where 
  secondary 
  hairs 
  occupy 
  the 
  positions 
  

   later 
  taken 
  possession 
  of 
  by 
  the 
  accessory 
  warts. 
  Secondary 
  hairs 
  are, 
  

   however, 
  numerous 
  on 
  the 
  prothoracic 
  shield, 
  and 
  show 
  their 
  knobbed 
  

   character 
  very 
  plainly. 
  All 
  the 
  primary 
  hairs 
  appear 
  to 
  be 
  slightly 
  

   knobbed, 
  but 
  not 
  thorned, 
  and 
  they 
  show 
  some 
  amount 
  of 
  tapering; 
  

   the 
  tubercles, 
  from 
  which 
  they 
  rise, 
  are 
  wart-like 
  in 
  character.
