  near 
  Reigate, 
  but 
  without 
  result, 
  and 
  when 
  these 
  were 
  finally 
  placed 
  

   on 
  Drosera 
  plants 
  sent 
  by 
  Bankes, 
  they 
  were 
  already 
  exhausted, 
  and 
  

   only 
  three 
  ultimately 
  survived 
  ; 
  these 
  seemed 
  more 
  at 
  home 
  on 
  the 
  

   Drosera 
  than 
  on 
  anything 
  yet 
  tried 
  ; 
  one 
  placed 
  on 
  a 
  leaf 
  was, 
  however, 
  

   in 
  process 
  of 
  digestion 
  next 
  morning 
  ; 
  the 
  others 
  had 
  disappeared 
  

   somewhere, 
  apparently 
  in 
  the 
  hearts 
  of 
  the 
  little 
  plants. 
  A 
  new 
  set 
  of 
  

   eggs 
  began 
  to 
  hatch 
  on 
  September 
  6th 
  (from 
  eggs 
  laid 
  by 
  a 
  2 
  captured 
  

   August 
  23rd); 
  much 
  time 
  was 
  spent 
  in 
  watching 
  the 
  young 
  larvae 
  on 
  

   the 
  plants 
  ; 
  none 
  were 
  placed 
  amongst 
  the 
  glands 
  on 
  the 
  leaves, 
  but 
  

   the 
  largest 
  of 
  the 
  unexpanded 
  leaves 
  was 
  selected. 
  They 
  eventually 
  

   got 
  down 
  towards 
  the 
  centre 
  of 
  the 
  plant, 
  and 
  became 
  much 
  more 
  quiet 
  

   and 
  sluggish 
  there, 
  but 
  still 
  on 
  the 
  move. 
  The 
  next 
  day 
  none 
  of 
  them 
  

   could 
  be 
  found. 
  September 
  14th 
  : 
  Looked 
  at 
  occasionally 
  ; 
  nothing 
  

   could 
  be 
  made 
  of 
  the 
  Drosera 
  plants, 
  but 
  to-day 
  a 
  careful 
  examination 
  

   shows 
  a 
  small 
  pile 
  of 
  frass, 
  near 
  the 
  centre, 
  in 
  two 
  of 
  the 
  plants. 
  

   Another 
  shows 
  nothing, 
  and 
  in 
  the 
  fourth 
  is 
  a 
  living 
  larva 
  of 
  pallidum, 
  

   a 
  little 
  grown, 
  but 
  out, 
  exposed, 
  and 
  looking 
  sluggish. 
  September 
  16th: 
  

   On 
  one 
  plant 
  a 
  small 
  larva, 
  by 
  the 
  conspicuousness 
  of 
  its 
  darkish 
  

   tubercles, 
  in 
  its 
  second 
  skin, 
  is 
  seen 
  down 
  amongst 
  the 
  leaf 
  -stems 
  just 
  

   outside 
  the 
  central 
  heart, 
  covered 
  by 
  a 
  slight 
  web 
  of 
  silk, 
  and 
  this 
  a 
  

   little 
  obscured 
  by 
  some 
  frass. 
  On 
  another 
  plant 
  a 
  small 
  larva 
  is 
  

   exposed 
  in 
  about 
  the 
  same 
  situation 
  ; 
  this 
  one 
  is 
  well-fed 
  up 
  in 
  first 
  

   skin. 
  September 
  11th: 
  The 
  larva 
  under 
  the 
  web 
  has 
  thickened 
  it, 
  both 
  

   with 
  silk 
  and 
  other 
  material 
  (frass 
  ?), 
  so 
  that 
  he 
  is 
  now 
  invisible. 
  On 
  

   another 
  plant 
  the 
  exposed 
  larva 
  is 
  now 
  quite 
  fat, 
  in 
  first 
  skin, 
  but 
  is 
  

   still 
  exposed. 
  September 
  22nd 
  : 
  The 
  cocoon 
  is 
  still 
  firm 
  and 
  opaque, 
  

   its 
  strong 
  structure 
  leads 
  one 
  to 
  suppose 
  it 
  is 
  for 
  hybernation. 
  It 
  is 
  

   placed 
  between 
  an 
  outer 
  dying 
  leaf 
  -stalk 
  (of 
  a 
  not 
  thriving 
  plant) 
  and 
  

   the 
  central 
  bud-bulb, 
  and 
  the 
  adjacent 
  leaf, 
  on 
  its 
  inner 
  side, 
  looks 
  as 
  if 
  

   dying 
  at 
  the 
  tip, 
  from 
  being 
  eaten 
  or 
  excavated 
  ; 
  this 
  is 
  the 
  only 
  point 
  

   to 
  suggest 
  that 
  the 
  larva 
  is 
  feeding. 
  The 
  "exposed" 
  larva, 
  though 
  

   looked 
  for 
  every 
  day, 
  has 
  been 
  invisible 
  since 
  the 
  17th, 
  and 
  it 
  was 
  feared 
  

   something 
  might 
  have 
  happened 
  to 
  it 
  ; 
  to-day, 
  however, 
  it 
  is 
  out, 
  

   crawling 
  over 
  the 
  minute 
  leaves 
  of 
  the 
  leaf-bud 
  in 
  the 
  centre 
  of 
  the 
  

   plant; 
  no 
  trace 
  is 
  seen 
  (of 
  course, 
  without 
  pulling 
  the 
  plant 
  to 
  pieces) 
  of 
  

   where 
  it 
  spent 
  the 
  interval. 
  It 
  is 
  now 
  in 
  the 
  second 
  instar. 
  September 
  

   24th: 
  A 
  plant, 
  in 
  w 
  T 
  hich 
  a 
  larva 
  was 
  placed, 
  September 
  6th, 
  and 
  of 
  

   which 
  no 
  trace 
  could 
  since 
  be 
  found, 
  although 
  the 
  plant 
  has 
  been 
  

   examined 
  most 
  carefully 
  nearly 
  every 
  day, 
  when 
  examined 
  to-day, 
  

   was 
  found 
  to 
  have 
  on 
  it 
  a 
  larva 
  in 
  second 
  skin, 
  which 
  was 
  constructing 
  

   a 
  silken 
  web 
  over 
  itself 
  at 
  the 
  side 
  of 
  the 
  central 
  bud, 
  and 
  close 
  to 
  the 
  

   base 
  of 
  a 
  larger 
  leaf. 
  No 
  trace 
  of 
  any 
  of 
  the 
  work 
  of 
  the 
  larva 
  in 
  the 
  

   interval 
  can 
  be 
  found. 
  The 
  larva, 
  found 
  on 
  the 
  17th, 
  has 
  thickened 
  its 
  

   web, 
  and 
  pellets 
  of 
  frass 
  are 
  conspicuous 
  on 
  its 
  upper 
  surface. 
  The 
  

   larva 
  can 
  still 
  be 
  faintly 
  outlined 
  beneath. 
  The 
  first 
  larva 
  is 
  quite 
  

   invisible. 
  October 
  22nd 
  : 
  The 
  three 
  inhabited 
  plants 
  are 
  not 
  looking 
  

   flourishing; 
  two, 
  which 
  have 
  the 
  largest 
  green 
  centres, 
  have 
  the 
  cocoons 
  

   as 
  last 
  described 
  ; 
  the 
  third, 
  however, 
  has 
  only 
  a 
  small 
  central 
  bit 
  of 
  

   gretn, 
  and 
  there 
  is 
  a 
  new 
  r 
  and 
  larger 
  cocoon 
  on 
  the 
  other 
  side 
  of 
  this 
  

   from 
  the 
  original 
  one, 
  that 
  does 
  not 
  look 
  much 
  different 
  ; 
  the 
  new 
  

   cocoon 
  is 
  still 
  imperfect, 
  and 
  one 
  glimpse 
  was 
  get 
  through 
  it 
  oi 
  the 
  

   black 
  head 
  of 
  the 
  larva 
  moving 
  about, 
  and 
  apparently 
  spinning, 
  and 
  

   again 
  of 
  the 
  body 
  of 
  the 
  larva, 
  of 
  which 
  no 
  details 
  appeared, 
  but 
  it
