  In 
  point 
  of 
  numbers 
  the 
  Satyrs 
  suffer 
  most, 
  as 
  might 
  have 
  

   been 
  expected. 
  It 
  is 
  quite 
  common 
  to 
  find 
  Melanitis 
  muti- 
  

   lated. 
  

  

  We 
  hope 
  to 
  gather 
  more 
  information 
  on 
  this 
  point 
  and 
  are 
  

   about 
  to 
  experiment 
  with 
  freshly 
  killed 
  protected 
  species 
  to 
  

   see 
  if 
  ants 
  can 
  find 
  them 
  when 
  they 
  are 
  placed 
  in 
  a 
  suitable 
  

   position 
  for 
  protection 
  to 
  act.

  VII. 
  Conclusions. 
  

  

  The 
  conclusions 
  to 
  be 
  drawn 
  from 
  these 
  observations 
  are: 
  — 
  

  

  1. 
  Mimicry 
  is 
  a 
  protection 
  from 
  foes 
  which 
  attack 
  butter- 
  

   flies 
  on 
  the 
  wing. 
  

  

  2. 
  Protective 
  resemblance 
  is 
  a 
  protection 
  from 
  foes 
  which 
  

   hunt 
  sleeping 
  prey. 
  

  

  3. 
  Mimicry 
  was 
  a 
  protection 
  from 
  birds. 
  

  

  4. 
  Birds 
  seldom 
  attack 
  butterflies 
  now, 
  but 
  butterfly- 
  

   catching 
  birds 
  were 
  formerly 
  more 
  plentiful. 
  

  

  5. 
  The 
  comparative 
  rarity 
  of 
  mimicry 
  shows 
  the 
  danger 
  

   to 
  have 
  been 
  of 
  relatively 
  short 
  duration. 
  

  

  6. 
  The 
  shyness 
  of 
  butterflies 
  is 
  further 
  proof 
  of 
  danger. 
  

   It 
  is 
  now 
  probably 
  an 
  inherited 
  instinct. 
  

  

  7. 
  Protective 
  resemblance 
  is 
  almost 
  universal. 
  

  

  8. 
  It 
  is 
  a 
  protection 
  during 
  the 
  sleeping-hours. 
  

  

  9. 
  Ants 
  seldom 
  capture 
  living 
  butterflies. 
  

  

  10. 
  The 
  symmetrical 
  mutilations 
  of 
  butterflies 
  points 
  to 
  

   lizards 
  and 
  perhaps 
  small 
  insectivorous 
  mammals 
  as 
  

   the 
  foes 
  which 
  hunt 
  for 
  sleeping 
  butterflies. 
  

  

  11. 
  The 
  amount 
  of 
  danger 
  feared 
  is 
  measurable 
  by 
  the 
  

   efforts 
  made 
  to 
  avoid 
  it.
