  was 
  decidedly 
  larger, 
  and 
  of 
  a 
  flesh 
  tint. 
  It 
  is 
  unfortunate 
  that 
  

   the 
  larva 
  was 
  not 
  seen 
  when 
  on 
  the 
  move, 
  and 
  transferred 
  to 
  a 
  

   better 
  plant, 
  and 
  a 
  description 
  of 
  it 
  taken. 
  The 
  presumption 
  is 
  that 
  it 
  

   is 
  now 
  in 
  its 
  third 
  skin. 
  October 
  2ith 
  : 
  This 
  larva 
  is 
  found 
  crawling 
  

   about 
  outside 
  to-day. 
  It 
  may 
  be 
  merely 
  in 
  second 
  stage, 
  although 
  

   two 
  days 
  since 
  noted 
  as 
  being 
  presumably 
  in 
  the 
  third 
  (see 
  infra). 
  

   October 
  27th: 
  The 
  larva 
  was 
  found 
  to 
  have 
  made 
  some 
  slight 
  spinning. 
  

   Yesterday 
  (October 
  26th) 
  the 
  spinning 
  formed 
  a 
  fairly 
  complete 
  cocoon, 
  

   with 
  some 
  black 
  dots 
  of 
  frass, 
  and 
  to-day 
  it 
  is 
  more 
  dense, 
  and 
  the 
  

   larva 
  is 
  completely 
  hidden. 
  November 
  20th: 
  Larva 
  (no. 
  2) 
  noted 
  27th, 
  

   remains 
  in 
  statu 
  quo. 
  Another 
  (no. 
  1) 
  is 
  found 
  to-day 
  to 
  have 
  begun 
  

   a 
  new 
  tent 
  ; 
  it 
  is 
  still 
  somewhat 
  visible 
  through 
  the 
  silk, 
  and 
  can 
  be 
  

   seen 
  to 
  be 
  fat, 
  and 
  larger, 
  if 
  anything, 
  than 
  no. 
  2 
  at 
  its 
  spinning, 
  but 
  

   no 
  details 
  are 
  discernible. 
  No. 
  3 
  has 
  its 
  cocoon 
  wet, 
  from 
  water 
  

   soaking 
  up 
  the 
  plant 
  ; 
  on 
  this 
  plant 
  the 
  central 
  bud 
  is 
  wet, 
  as 
  it 
  is 
  not 
  

   in 
  plants 
  of 
  1 
  and 
  2. 
  The 
  cocoon 
  does 
  not 
  look 
  very 
  satisfactory, 
  and 
  

   possibly 
  the 
  larva 
  inside 
  is 
  not 
  doing 
  very 
  well. 
  December 
  10th, 
  1904 
  : 
  

   No. 
  2 
  (of 
  November 
  20th) 
  is 
  found 
  to-day 
  outside 
  its 
  tent, 
  on 
  the 
  

   move, 
  and 
  opportunity 
  taken 
  to 
  describe 
  it. 
  It 
  does 
  not 
  seem 
  to 
  have 
  

   grown, 
  or 
  to 
  be 
  in 
  feeding-humour 
  — 
  moves 
  very 
  sluggishly. 
  January 
  

   14:th, 
  1905 
  : 
  Not 
  liking 
  the 
  look 
  of 
  my 
  plants, 
  I 
  examined 
  them 
  ; 
  the 
  

   first 
  was 
  dead, 
  remains 
  of 
  a 
  larval 
  head 
  detected 
  ; 
  the 
  second 
  was 
  alive, 
  

   but 
  no 
  trace 
  of 
  larva 
  could 
  be 
  found 
  ; 
  the 
  third 
  contained 
  a 
  larva, 
  

   which 
  was 
  preserved, 
  lest 
  worse 
  befall 
  him. 
  He 
  seemed 
  much 
  as 
  

   described 
  at 
  the 
  last 
  entry. 
  The 
  cavity, 
  containing 
  his 
  cocoon, 
  was 
  

   excavated 
  towards 
  the 
  heart 
  of 
  the 
  button, 
  or 
  bud, 
  of 
  the 
  plant, 
  several 
  

   of 
  the 
  small 
  undeveloped 
  leaves 
  (?) 
  being 
  well 
  eaten 
  into. 
  This 
  bud 
  

   was 
  preserved 
  in 
  formalin. 
  When 
  the 
  cocoon 
  was 
  removed, 
  the 
  eaten 
  

   portion, 
  or 
  rather 
  what 
  was 
  not 
  eaten, 
  formed 
  a 
  small 
  hollow, 
  into 
  

   which, 
  or 
  on 
  to 
  which, 
  the 
  cocoon 
  would 
  just 
  fit. 
  This 
  closed 
  the 
  

   campaign 
  with 
  the 
  1901 
  eggs. 
  It 
  appeared 
  from 
  this 
  that 
  the 
  young 
  

   larva 
  feeds 
  somewhere 
  in 
  the 
  centre 
  of 
  the 
  plant 
  as 
  an 
  internal 
  feeder, 
  

   and 
  finally 
  makes 
  a 
  cocoon 
  in 
  the 
  heart 
  of 
  the 
  plant 
  for 
  hybernation. 
  

   The 
  one 
  cocoon, 
  of 
  which 
  I 
  made 
  the 
  most 
  satisfactory 
  examination, 
  

   consisted 
  of 
  a 
  cavity, 
  the 
  greater 
  part 
  of 
  which 
  was 
  excavated 
  out 
  of 
  

   the 
  material 
  of 
  the 
  outer 
  leaves 
  of 
  the 
  centre 
  bud 
  (winter 
  bulb), 
  and 
  

   completed 
  by 
  a 
  silken 
  cover. 
  This 
  renders 
  it 
  certain 
  that 
  some 
  of 
  the 
  

   central 
  material 
  of 
  the 
  plant 
  is 
  eaten 
  ; 
  but 
  for 
  this, 
  my 
  experience 
  in 
  

   1905 
  would 
  have 
  led 
  me 
  to 
  suspect 
  that 
  the 
  young 
  larva? 
  fed 
  on 
  the 
  

   leaves, 
  as 
  those 
  of 
  the 
  summer 
  brood 
  do. 
  The 
  larvae, 
  in 
  their 
  first 
  

   instar, 
  on 
  the 
  leaves, 
  are 
  often 
  very 
  difficult 
  to 
  see 
  and 
  find, 
  even 
  when 
  

   one 
  is 
  sure 
  they 
  are 
  there, 
  so 
  that, 
  in 
  my 
  ignorance, 
  in 
  1904, 
  I 
  might 
  

   easily 
  have 
  overlooked 
  them. 
  I 
  am 
  still 
  inclined 
  to 
  suspect 
  that 
  it 
  is 
  

   possible 
  that, 
  in 
  the 
  first 
  instar, 
  they 
  feed 
  on 
  the 
  leaves, 
  in 
  the 
  same 
  

   way 
  as 
  the 
  summer 
  brood 
  do, 
  and 
  only 
  descend 
  to 
  the 
  centre 
  of 
  the 
  

   plant 
  in 
  the 
  second 
  instar. 
  Against 
  this 
  is 
  the 
  fact 
  that 
  the 
  young 
  

   larvae 
  directed 
  their 
  wanderings 
  to 
  the 
  centre 
  of 
  the 
  plant, 
  and 
  that 
  

   the 
  centre 
  was 
  found 
  to 
  have 
  afforded 
  a 
  good 
  deal 
  of 
  food 
  material. 
  

   The 
  note 
  in 
  describing 
  one 
  larva, 
  as 
  to 
  the 
  presence 
  of 
  secondary 
  hairs 
  

   (October 
  22nd), 
  and 
  the 
  surmise 
  that 
  it 
  was 
  in 
  third 
  instar, 
  agrees 
  

   with 
  later 
  observations 
  ; 
  it 
  is 
  probable 
  that 
  this 
  larva 
  was 
  endeavour- 
  

   ing 
  to 
  complete 
  its 
  cycle 
  without 
  hybernating, 
  and 
  really 
  was 
  in 
  the 
  

   third 
  instar, 
  as 
  the 
  second 
  instar 
  larvae 
  do 
  not 
  show 
  any 
  secondary
