  The 
  typical 
  form 
  of 
  our 
  English 
  species 
  did 
  not 
  occur 
  where 
  

   I 
  took 
  my 
  three 
  ' 
  pica,' 
  for, 
  although 
  travelling 
  at 
  the 
  time, 
  

   I 
  worked 
  for 
  an 
  hour 
  or 
  more, 
  without 
  success, 
  to 
  take 
  a 
  

   better 
  series 
  of 
  what 
  I 
  saw 
  was 
  a 
  species 
  unknown 
  to 
  me. 
  

   The 
  place 
  was 
  in 
  a 
  slight 
  opening 
  in 
  a 
  very 
  thick 
  and 
  dark 
  

   forest 
  of 
  Redwoods 
  (Sequoia 
  sempervirens), 
  and 
  if 
  darkness 
  

   with 
  moisture 
  has 
  a 
  tendency, 
  as 
  has 
  been 
  supposed, 
  to 
  produce 
  

   melanic 
  coloration, 
  it 
  is 
  possible 
  that 
  further 
  search 
  in 
  Ihe 
  

   Scotch 
  locality 
  may 
  disclose 
  intermediate 
  varieties 
  and 
  connect 
  

   pica 
  with 
  punctidactyla. 
  So 
  far 
  as 
  I 
  know 
  the 
  four 
  examples 
  

   mentioned 
  are 
  the 
  only 
  known 
  specimens 
  of 
  this 
  species, 
  which 
  

   I 
  cannot 
  regard 
  as 
  a 
  mere 
  variety 
  xmtil 
  a 
  series 
  including 
  males 
  

   can 
  be 
  examined. 
  Fernald 
  was 
  unacquainted 
  with 
  it 
  when 
  

   studying 
  the 
  genitaha 
  of 
  the 
  North 
  American 
  Pterophoridae.'"

  the

  — 
  " 
  In 
  Proc. 
  Ent. 
  Soc, 
  1915, 
  p. 
  Ixi, 
  you 
  com- 
  

   mented 
  upon 
  the 
  recent 
  introduction 
  of 
  Hypolimnas 
  bolina, 
  L., 
  

   into 
  Madagascar 
  and 
  its 
  extraordinarily 
  rapid 
  increase. 
  Your 
  

   remarks 
  on 
  the 
  subject, 
  recalled 
  to 
  my 
  mind 
  a 
  somewhat 
  

   similar 
  occurrence 
  ; 
  i. 
  e. 
  the 
  suddenly 
  rapid 
  increase 
  in 
  Hama- 
  

   numida 
  daedalus, 
  F., 
  in 
  our 
  coastal 
  areas. 
  Up 
  to 
  about 
  the 
  

   year 
  1891 
  it 
  was, 
  with 
  us, 
  a 
  decided 
  rarity, 
  much 
  as 
  Acraea 
  

   satis, 
  Ward, 
  is 
  to-day. 
  It 
  appeared 
  to 
  increase 
  very 
  rapidly 
  

   about 
  that 
  year, 
  and 
  has 
  since 
  maintained 
  itself 
  as 
  a 
  decidedly 
  

   common 
  insect 
  about 
  roads 
  and 
  paths. 
  It 
  is 
  not 
  so 
  

   plentiful 
  in 
  Durban 
  and 
  the 
  coastal 
  flats 
  as 
  upon 
  hill-side 
  

   roads 
  and 
  paths 
  behind.
