  and 
  only 
  the 
  long 
  central 
  one 
  of 
  the 
  back 
  row 
  is 
  clearly 
  seen. 
  Of 
  the 
  

   usual 
  four 
  pairs 
  of 
  hairs 
  on 
  the 
  meso- 
  and 
  metathorax, 
  the 
  third 
  appears 
  

   to 
  be 
  represented 
  by 
  one 
  hair 
  only. 
  The 
  props 
  of 
  prolegs 
  are 
  about 
  

   O-04mm. 
  long, 
  with 
  three 
  crochets, 
  four 
  on 
  claspers. 
  Second 
  instar 
  

   (September 
  22nd, 
  1S04) 
  : 
  About 
  l-5mm. 
  long; 
  head 
  dark, 
  of 
  about 
  same 
  

   width 
  as 
  body 
  ; 
  tubercles 
  i 
  and 
  ii 
  are 
  on 
  one 
  large 
  chitinous 
  base 
  ; 
  iii, 
  

   iv, 
  and 
  v, 
  are 
  smaller. 
  These 
  bases 
  have 
  a 
  slightly 
  dark 
  tint; 
  the 
  hairs 
  

   are 
  long, 
  ii 
  nearly 
  as 
  long 
  as 
  width 
  of 
  body, 
  i 
  perhaps 
  a 
  quarter 
  of 
  ii, 
  

   iii 
  long, 
  iv 
  and 
  v 
  each 
  rather 
  shorter. 
  The 
  larva 
  might 
  be 
  described 
  

   as 
  pale 
  whitish-fuscous, 
  with 
  a 
  reddish 
  dorsal 
  line, 
  and 
  another 
  between 
  

   ii 
  and 
  iii, 
  but 
  it 
  seems 
  more 
  accurate 
  to 
  say 
  the 
  ground 
  colour 
  is 
  pale 
  

   reddish-brown, 
  and 
  that 
  there 
  is 
  a 
  narrow 
  white 
  line 
  round 
  each 
  large 
  

   tubercular 
  plate. 
  The 
  larva 
  being 
  young, 
  in 
  this 
  instance 
  i 
  and 
  ii 
  

   reach 
  practically 
  from 
  front 
  to 
  back 
  of 
  segment, 
  leaving 
  only 
  room 
  for 
  

   the 
  narrow 
  pale 
  line. 
  The 
  hairs 
  are 
  very 
  distinctly 
  thickened 
  at 
  the 
  

   tips. 
  The 
  larvae 
  hybernate 
  apparently 
  in 
  this 
  in 
  star, 
  forming 
  little 
  

   cocoons 
  amongst 
  the 
  small 
  leaves 
  of 
  the 
  winter 
  buds. 
  One 
  larva, 
  

   however, 
  in 
  November, 
  1904, 
  apparently 
  went 
  on 
  to 
  the 
  Third 
  instar 
  

   (but 
  may 
  still 
  only 
  be 
  in 
  the 
  second) 
  (October 
  24th, 
  1904) 
  : 
  It 
  is 
  fully 
  

   2mm. 
  long, 
  head 
  black, 
  general 
  tint 
  flesh-colour, 
  made 
  up 
  of 
  white 
  and 
  

   reddish 
  markings. 
  The 
  tubercles 
  i 
  and 
  ii 
  are 
  united 
  on 
  one 
  base 
  ; 
  ii 
  

   carries 
  the 
  longest 
  hair. 
  Base 
  of 
  hairs, 
  and 
  spiracles, 
  dark 
  ; 
  1st 
  thoracic 
  

   plate 
  has 
  a 
  white 
  central 
  line, 
  with 
  black 
  line 
  on 
  each 
  side, 
  and 
  a 
  black 
  

   spot 
  further 
  out. 
  Each 
  tubercle 
  is 
  surrounded 
  by 
  a 
  white 
  area 
  ; 
  between 
  

   is 
  dull 
  red 
  ; 
  the 
  red 
  area 
  has 
  fine 
  skin-points, 
  which 
  are 
  absent, 
  or 
  very 
  

   indistinct, 
  in 
  the 
  white 
  areas. 
  Hairs 
  slightly 
  clubbed, 
  that 
  on 
  

   iii 
  bent 
  forwards, 
  the 
  front 
  (upper) 
  one 
  of 
  iv 
  + 
  v 
  directed 
  rather 
  

   forwards, 
  shorter 
  than 
  the 
  posterior, 
  which 
  is 
  directed 
  outwards. 
  

   The 
  white 
  and 
  red 
  are, 
  perhaps, 
  better 
  described 
  as 
  being 
  in 
  

   longitudinal 
  lines, 
  a 
  red 
  dorsal 
  one, 
  then 
  a 
  broad 
  white 
  one, 
  

   including 
  i 
  and 
  ii, 
  then 
  a 
  red 
  one, 
  which 
  has 
  various 
  processes, 
  so 
  

   that 
  the 
  description 
  of 
  the 
  white 
  circles 
  round 
  the 
  tubercles 
  results 
  

   from 
  these 
  taking 
  circular 
  arcs, 
  with 
  the 
  tubercles, 
  spiracles, 
  etc., 
  for 
  

   centres. 
  But 
  there 
  are 
  other 
  centres 
  with 
  white, 
  that 
  are 
  not 
  at 
  present 
  

   occupied 
  by 
  tubercles. 
  On 
  the 
  1st 
  segment 
  is 
  a 
  little 
  longitudinal 
  

   stripe 
  of 
  red, 
  from 
  i 
  forwards, 
  and, 
  on 
  the 
  thorax, 
  the 
  dorsal 
  and 
  next 
  

   red 
  line 
  are 
  more 
  or 
  less 
  conjoined. 
  Under 
  low 
  magnification, 
  the 
  

   thoracic 
  plate 
  looks 
  nearly 
  black, 
  and 
  somewhat 
  homogeneous 
  in 
  

   colour. 
  Inside 
  i 
  and 
  ii 
  is 
  a 
  dark 
  depressed 
  spot. 
  Anal 
  plate 
  not 
  dark. 
  

   [The 
  larva 
  is 
  not 
  tormented 
  to 
  get 
  a 
  fuller 
  description, 
  but 
  is 
  carefully 
  

   placed 
  on 
  a 
  better 
  plant 
  in 
  hopes 
  of 
  rearing 
  it.] 
  * 
  Same 
  larva 
  (December 
  

   10th, 
  1904) 
  : 
  Short 
  and 
  thick; 
  yellow, 
  with 
  very 
  large 
  porcellanous- 
  

   white 
  plates, 
  or, 
  perhaps, 
  is 
  rather 
  porcellanous-white 
  with 
  certain 
  

   yellow, 
  or 
  orange-ochreous, 
  lines. 
  The 
  plates 
  being 
  apparently 
  

   surroundings 
  of 
  tubercle, 
  the 
  tubercle 
  and 
  hairs 
  are 
  black, 
  so 
  that 
  the 
  

   little 
  larva 
  is 
  a 
  rather 
  striking 
  object 
  when 
  closely 
  examined. 
  Length, 
  

   when 
  stretched, 
  2-7mm. 
  Taking 
  the 
  white 
  as 
  the 
  ground 
  colour, 
  there 
  

   is 
  a 
  narrow, 
  dorsal, 
  orange 
  line, 
  a 
  little 
  widened 
  in 
  front 
  oi 
  each 
  

   segment, 
  and 
  sending 
  branches, 
  pale 
  and 
  less 
  conspicuous, 
  along 
  the

  The 
  endeavour 
  to 
  describe 
  this 
  lawn, 
  without 
  disturbing 
  it. 
  probably 
  explain 
  

   why 
  it 
  is 
  said 
  [Trans. 
  Ent. 
  Soc. 
  Loud., 
  1906, 
  p. 
  186) 
  to 
  have 
  had 
  secondary 
  hairs 
  

   which 
  the 
  further 
  note 
  shows 
  to 
  have 
  been 
  an 
  error 
  (Chapman).
