  hairs. 
  This 
  larva 
  probably 
  perished 
  earlier 
  than 
  the 
  others. 
  So 
  the 
  

   matter 
  remained 
  for 
  further 
  investigation 
  in 
  1905. 
  The 
  larva, 
  like 
  so 
  

   many 
  of 
  the 
  Platyptiliid 
  division 
  of 
  the 
  "plumes," 
  clearly 
  hybernates 
  

   full-grown 
  in 
  its 
  second 
  instar, 
  and 
  ought 
  to 
  be 
  discoverable 
  in 
  the 
  

   spring 
  in 
  its 
  further 
  stages. 
  I 
  owe 
  it 
  to 
  Mr. 
  South 
  that 
  I 
  was 
  able 
  

   to 
  visit 
  a 
  locality 
  for 
  the 
  species, 
  and 
  to 
  continue 
  the 
  observations 
  in 
  

   1905. 
  Of 
  course 
  I 
  did 
  not 
  quite 
  know 
  what 
  to 
  look 
  for, 
  but, 
  as 
  good 
  luck 
  

   would 
  have 
  it, 
  the 
  discovery 
  of 
  the 
  larva 
  in 
  the 
  spring 
  proved 
  fairly 
  

   easy. 
  May 
  31st, 
  1905 
  : 
  Accompanied 
  Mr. 
  South 
  to 
  a 
  locality 
  in 
  the 
  

   Esher 
  district 
  of 
  Surrey, 
  where 
  Drosera 
  is 
  found, 
  and 
  where 
  B. 
  

   pallidum 
  had 
  been 
  taken, 
  and 
  searched 
  for 
  larvae 
  of 
  B. 
  pallidum, 
  and 
  

   found 
  about 
  a 
  score. 
  The 
  first 
  specimen 
  was 
  found 
  seated 
  on 
  the 
  

   underside 
  of 
  the 
  petiole 
  of 
  a 
  leaf 
  of 
  Drosera. 
  It 
  was 
  nearly 
  full-grown, 
  

   and 
  was 
  of 
  about 
  the 
  length 
  of 
  the 
  petiole. 
  This 
  will 
  give 
  some 
  idea 
  of 
  

   the 
  size 
  and 
  state 
  of 
  the 
  plants, 
  which 
  were 
  growing 
  on 
  peaty 
  ground 
  

   amongst 
  heath, 
  and 
  apart 
  from 
  Sphagnum 
  ; 
  most 
  of 
  them 
  were 
  very 
  small, 
  

   with 
  the 
  leaves 
  lying 
  flat 
  to 
  the 
  ground, 
  the 
  one 
  above 
  noted 
  being 
  a 
  fine 
  

   specimen, 
  about 
  twice 
  the 
  size 
  of 
  the 
  majority. 
  There 
  had 
  been 
  a 
  

   drought 
  for 
  a 
  considerable 
  period 
  before 
  this, 
  and 
  the 
  ground 
  was 
  by 
  no 
  

   means 
  boggy. 
  The 
  small 
  size 
  was 
  more 
  probably 
  due 
  to 
  drought 
  than 
  to 
  

   the 
  period 
  of 
  the 
  season. 
  A 
  fine 
  plant 
  would 
  be 
  35mm. 
  across 
  only, 
  

   majority 
  2 
  5mm. 
  -30mm., 
  and 
  some 
  only 
  20mm., 
  and 
  even 
  less. 
  The 
  

   remaining 
  larvae 
  were 
  found 
  in 
  various 
  positions, 
  some 
  on 
  the 
  petioles, 
  

   some 
  under, 
  and 
  some 
  on 
  top 
  of, 
  the 
  leaves, 
  and 
  some 
  sitting 
  across 
  the 
  

   centre 
  of 
  the 
  little 
  plants. 
  In 
  no 
  case, 
  either 
  in 
  the 
  field, 
  or 
  in 
  various 
  

   observations 
  afterwards 
  at 
  home, 
  did 
  a 
  larva 
  place 
  himself 
  on 
  the 
  top 
  

   of 
  a 
  sound, 
  healthy, 
  leaf. 
  They 
  seemed 
  on 
  the 
  whole, 
  however, 
  to 
  be 
  

   rather 
  reckless 
  in 
  the 
  way 
  they 
  moved 
  about 
  amongst 
  them. 
  Their 
  

   hairs 
  probably 
  protect 
  them 
  against 
  contact 
  with 
  the 
  leaf-glands, 
  

   unless 
  they 
  actually 
  wulk 
  over 
  them. 
  They 
  would 
  eat 
  any 
  part 
  of 
  the 
  

   plant, 
  least 
  frequently, 
  however, 
  attacking 
  the 
  central 
  bud. 
  The 
  most 
  

   usual 
  point 
  of 
  attack 
  was 
  the 
  margin 
  of 
  the 
  leaf, 
  approached 
  by 
  the 
  

   larva 
  seated 
  on 
  the 
  petiole 
  or 
  beneath 
  the 
  leaf, 
  and, 
  in 
  several 
  cases, 
  the 
  

   attack 
  was 
  continued 
  till 
  the 
  whole 
  leaf 
  was 
  eaten, 
  and 
  a 
  portion 
  of 
  the 
  

   petiole 
  also. 
  In 
  one 
  or 
  two 
  cases 
  the 
  larva 
  attacked, 
  and 
  ate, 
  the 
  

   glandular 
  processes, 
  until 
  it 
  had 
  cleared 
  the 
  middle 
  of 
  a 
  leaf, 
  which 
  

   then 
  formed 
  its 
  resting-place. 
  Twice 
  a 
  larva, 
  looking 
  for 
  a 
  place 
  to 
  

   pupate, 
  escaped 
  from 
  a 
  flower-pot 
  by 
  crossing 
  the 
  water 
  in 
  the 
  saucer, 
  

   so 
  that 
  they 
  are 
  probably 
  able 
  to 
  deal 
  wiih 
  the 
  habitat, 
  when 
  flooded, 
  

   without 
  much 
  injury. 
  The 
  larva 
  is 
  a 
  brownish-red 
  above, 
  varying 
  

   from 
  rather 
  dark 
  to 
  a 
  bright 
  rosy 
  colour, 
  and 
  sometimes 
  with 
  some 
  

   greenish 
  shades 
  ; 
  beneath, 
  it 
  is 
  green. 
  The 
  dorsal 
  tubercles 
  are 
  darker 
  

   and 
  more 
  rosy, 
  and 
  retain 
  a 
  bright 
  rose-colour, 
  whilst 
  the 
  rest 
  of 
  the 
  

   larva, 
  when 
  fixed 
  for 
  pupation, 
  becomes 
  quite 
  green 
  ; 
  the 
  colour 
  

   involves 
  not 
  only 
  the 
  tubercles, 
  but 
  a 
  little 
  of 
  the 
  base 
  around 
  them, 
  

   especially 
  behind. 
  The 
  hairs 
  are 
  long, 
  and 
  slightly 
  clubbed, 
  or 
  rather 
  

   flattened 
  at 
  the 
  end, 
  and 
  so 
  the 
  ends 
  reflect 
  light 
  so 
  as 
  to 
  look 
  larger 
  

   than 
  they 
  actually 
  are. 
  The 
  resulting 
  appearance 
  of 
  the 
  larva 
  is 
  that 
  

   it 
  looks 
  very 
  much 
  like 
  some 
  aspects 
  of 
  the 
  Drosera 
  leaf, 
  sometimes 
  

   the 
  hairs, 
  sometimes 
  the 
  red 
  tubercles, 
  suggesting 
  the 
  glands, 
  and 
  their 
  

   supports, 
  on 
  the 
  1 
  hosera 
  leaves, 
  and 
  the 
  general 
  tone 
  of 
  colour 
  is 
  much 
  

   that 
  of 
  the 
  green 
  leaf 
  seen 
  through 
  the 
  forest 
  of 
  rosy 
  hairs. 
  In 
  looking 
  

   for 
  a 
  larva, 
  a 
  slightly 
  edgewise 
  view 
  of 
  a 
  leaf 
  often 
  suggests 
  a 
  larva,
