﻿New 
  Hebrides, 
  and 
  New 
  Caledonia, 
  and 
  the 
  still 
  more 
  richly 
  

   coloured 
  ^M^c^ra, 
  Butl., 
  of 
  the 
  latter 
  island, 
  and 
  rarik, 
  Esch., 
  of 
  

   the 
  scattered 
  groups 
  to 
  the 
  northward. 
  Nearly 
  all 
  the 
  specimens 
  

   that 
  I 
  have 
  seen 
  from 
  the 
  Friendly 
  Islands 
  (Tonga) 
  are, 
  on 
  the 
  

   contrary, 
  smaller 
  and 
  more 
  poorly 
  marked 
  than 
  those 
  from 
  any 
  

   other 
  locality, 
  but 
  those 
  that 
  I 
  bred 
  from 
  larvae 
  found 
  in 
  

   Rarotonga 
  and 
  Aitutaki 
  are 
  very 
  handsome, 
  and 
  the 
  females 
  

   are 
  for 
  the 
  most 
  part 
  intermediate 
  between 
  the 
  fulvous 
  Fijian 
  

   form 
  and 
  the 
  large 
  dark 
  race 
  occurring 
  in 
  Tahiti. 
  The 
  markings 
  

   of 
  the 
  females 
  from 
  the 
  Society 
  Islands 
  approximate 
  more 
  

   nearly 
  to 
  those 
  of 
  the 
  male 
  than 
  is 
  the 
  case 
  with 
  any 
  that 
  I 
  

   met 
  with 
  elsewhere, 
  except 
  in 
  the 
  Marquesas, 
  where 
  the 
  local 
  

   race 
  of 
  H. 
  holina 
  differs 
  from 
  that 
  of 
  Tahiti 
  chiefly 
  in 
  its 
  smaller 
  

   average 
  size 
  and 
  somewhat 
  darker 
  general 
  colouring. 
  

  

  The 
  above 
  instances 
  convey 
  only 
  a 
  faint 
  idea 
  of 
  the 
  mar- 
  

   vellous 
  range 
  of 
  variation 
  in 
  the 
  female 
  of 
  this 
  most 
  interesting 
  

   butterfly, 
  which 
  can 
  be 
  realised 
  only 
  by 
  the 
  inspection 
  of 
  the 
  

   extensive 
  series 
  from 
  the 
  whole 
  of 
  the 
  area 
  of 
  its 
  distribution, 
  

   contained 
  in 
  the 
  National 
  Collection, 
  or 
  the 
  almost 
  equally 
  

   fine 
  series 
  in 
  the 
  Oxford 
  University 
  Museum. 
  

  

  It 
  is 
  not 
  my 
  intention 
  at 
  present 
  to 
  discuss 
  the 
  means 
  by 
  

   which 
  butterflies 
  have 
  been 
  dispersed 
  over 
  the 
  oceans 
  to 
  the 
  

   most 
  remote 
  islands, 
  especially 
  as 
  this 
  subject 
  has 
  been 
  

   treated 
  somewhat 
  fully 
  by 
  me 
  in 
  the 
  case 
  of 
  Danaida 
  ■plexippus, 
  

   in 
  the 
  volume 
  of 
  the 
  " 
  Entomologist's 
  Monthly 
  Magazine 
  " 
  for 
  

   1914. 
  The 
  brief 
  bibliography 
  and 
  sketch-map 
  appended 
  to 
  

   this 
  Address 
  will, 
  I 
  trust, 
  enable 
  any 
  one 
  who 
  is 
  interested 
  in 
  

   the 
  geographical 
  distribution 
  of 
  butterflies, 
  to 
  follow 
  these 
  

   frail 
  creatures 
  to 
  their 
  ultimate 
  limits 
  on 
  the 
  earth's 
  surface, 
  

   and 
  to 
  travel 
  in 
  imagination 
  to 
  the 
  Fringes 
  of 
  Butterfly 
  Life.
