﻿In 
  recent 
  years 
  tlie 
  Fauna 
  and 
  Flora 
  of 
  the 
  numerous 
  small 
  

   islands 
  scattered 
  over 
  the 
  Indian 
  Ocean 
  have 
  been 
  investi- 
  

   gated 
  by 
  successive 
  scientific 
  expeditions 
  in 
  a 
  fairly 
  exhaustive 
  

   manner, 
  and 
  we 
  now 
  possess 
  a 
  tolerably 
  complete 
  knowledge 
  

   of 
  their 
  insect 
  jjroductions. 
  I 
  purposely 
  omit 
  any 
  reference 
  

   to 
  the 
  Comoro 
  Islands, 
  Mauritius, 
  and 
  Bourbon 
  (which 
  may 
  be 
  

   regarded 
  as 
  'satellites 
  to 
  the 
  almost 
  continental 
  island 
  of 
  Mada- 
  

   gascar) 
  except 
  to 
  recall 
  to 
  mind 
  the 
  very 
  valuable 
  paper 
  by 
  the 
  

   late 
  Colonel 
  Manders 
  on 
  the 
  butterflies 
  of 
  the 
  two 
  latter 
  islands, 
  

   which 
  appeared 
  in 
  our 
  Transactions 
  for 
  1907. 
  The 
  eleven 
  

   species 
  recorded 
  from 
  Rodriguez, 
  300 
  miles 
  east 
  of 
  Mauritius, 
  

   are 
  all 
  found 
  commonly 
  in 
  that 
  island 
  and 
  in 
  Bourbon. 
  From 
  

   the 
  lofty 
  and 
  luxuriantly 
  wooded 
  Seychelles 
  group, 
  which 
  are 
  

   exceptional 
  among 
  oceanic 
  islands 
  from 
  their 
  granitic 
  forma- 
  

   tion, 
  twenty-two 
  species 
  of 
  butterflies 
  have 
  been 
  recorded, 
  

   six 
  of 
  these 
  being, 
  however, 
  somewhat 
  doubtful. 
  These 
  

   include 
  one 
  Pa'pilio, 
  a 
  dwarf 
  form 
  {nana, 
  Obth.) 
  of 
  the 
  Mas- 
  

   carene 
  P. 
  tUsparilis, 
  Boisd. 
  ; 
  and 
  the 
  handsome 
  and 
  peculiar 
  

   Euploea 
  {Pramasa) 
  mitra, 
  Moore, 
  and 
  Atella 
  philiberti, 
  Joannis, 
  

   are 
  confined 
  to 
  the 
  Seychelles 
  and 
  to 
  the 
  great 
  atoll 
  of 
  Aldabra, 
  

   a 
  long 
  way 
  to 
  the 
  south-west. 
  This 
  latter 
  island 
  is 
  the 
  sole 
  

   locality 
  of 
  a 
  very 
  fine 
  and 
  distinct 
  species 
  of 
  the 
  characteristic 
  

   African 
  genus 
  Teracoliis 
  {aldabrensis 
  , 
  Holland). 
  The 
  coralline 
  

   Almirantes 
  have 
  apparently 
  only 
  three 
  butterflies, 
  a 
  small 
  

   PampJiila 
  also 
  found 
  in 
  the 
  Seychelles, 
  and 
  two 
  well-known 
  

   European 
  " 
  blues," 
  Zizera 
  lysimon, 
  Hiibn., 
  and 
  Tarucus 
  teli- 
  

   canus, 
  Hiibn., 
  both 
  also 
  plentiful 
  in 
  the 
  Mascarene 
  Islands. 
  

   On 
  Glorioso 
  atoll 
  Mr. 
  M. 
  J. 
  Nicoll 
  in 
  the 
  " 
  Valhalla 
  " 
  found 
  

   butterflies 
  and 
  a 
  day-flying 
  Sphingid 
  in 
  numbers, 
  one 
  of 
  the 
  

   former 
  being 
  Hypolimnas 
  niisip2'>us 
  ; 
  and 
  in 
  the 
  Chagos 
  group 
  

   Dr. 
  G. 
  C. 
  Bourne 
  met 
  with 
  the 
  widely 
  ranging 
  Precis 
  villida, 
  F., 
  

   and 
  a 
  very 
  fine 
  and 
  well-marked 
  race 
  of 
  Hypolimnas 
  bolina, 
  L. 
  

   Only 
  two 
  butterflies, 
  also 
  of 
  the 
  most 
  extended 
  distribution, 
  

   Limnas 
  chrysipjnis 
  and 
  Pyrameis 
  car 
  did, 
  are 
  recorded 
  from 
  

   the 
  great 
  coral 
  archipelago 
  of 
  the 
  Maldives. 
  The 
  little 
  Cocos- 
  

   Keeling 
  atoll 
  has 
  produced 
  five 
  species, 
  two 
  of 
  which, 
  Precis 
  

   villida 
  and 
  Limnas 
  cJirysipjnis 
  var. 
  petilia, 
  Stoll, 
  were 
  observed 
  

   by 
  me 
  in 
  my 
  flying 
  visit 
  to 
  the 
  island 
  in 
  January 
  1904. 
  The 
  

   other 
  three 
  are 
  Hypolimnas 
  misippus, 
  H, 
  bolina, 
  and 
  Pyrameis
