  Holochila

  so 
  curiously 
  suggestive 
  in 
  its 
  

   coloration 
  of 
  a 
  mixture 
  of 
  our

  Lampides 
  boeticus, 
  which 
  is 
  common 
  and 
  occurs 
  up 
  

   to 
  6000 
  feet 
  elevation, 
  is 
  probably 
  truly 
  indigenous 
  also, 
  while 
  

   Danaida 
  j^lexijJj^us, 
  Pyrameis 
  atalanta, 
  and 
  P. 
  hunter 
  a, 
  L., 
  

   represent 
  the 
  American 
  element 
  of 
  the 
  fauna, 
  and 
  P. 
  cardui, 
  

   which 
  according 
  to 
  Dr. 
  K. 
  C. 
  L. 
  Perkins 
  frequently 
  shows 
  a 
  

   strong 
  tendency 
  towards 
  the 
  form 
  {kershawii) 
  characteristic 
  

   of 
  Australia, 
  may 
  have 
  been 
  derived 
  from 
  that 
  region. 
  Neither 
  

   of 
  the 
  two 
  predominant 
  butterflies 
  of 
  the 
  Indo-Pacific 
  region, 
  

   HypoUmnas 
  bolina 
  and 
  Precis 
  villida, 
  appear 
  to 
  have 
  reached 
  

   the 
  Hawaiian 
  Islands 
  up 
  to 
  the 
  present 
  date. 
  

  

  Crossing

   Island 
  in 
  the 
  little-visited 
  Revillagigedo 
  group, 
  south 
  of 
  Lower 
  

   California 
  and 
  separated 
  by 
  300 
  miles 
  of 
  deep 
  sea 
  from 
  the 
  main- 
  

   land, 
  has 
  produced 
  three 
  butterflies, 
  two 
  small 
  Ltjcaenidae 
  and 
  

   a 
  sub-species 
  of 
  Papilio

  The 
  Galapagos 
  Islands, 
  

   situated 
  on 
  the 
  Equator 
  700 
  miles 
  from 
  the 
  nearest 
  point 
  of 
  

   South 
  America, 
  are 
  very 
  poor 
  in 
  insect 
  life, 
  though 
  their 
  fauna 
  

   is 
  otherwise 
  of 
  classical 
  interest. 
  The 
  six 
  known 
  butterflies 
  

   are 
  all 
  of 
  American 
  type 
  ; 
  two 
  of 
  them, 
  Lycaena 
  parrhasioides 
  , 
  

   Wallgr., 
  and 
  Eudamus 
  galapagensis, 
  Williams, 
  are 
  peculiar 
  

   to 
  the 
  islands, 
  and 
  the 
  others 
  are 
  Callidryas 
  euhule, 
  L., 
  Agraulis 
  

   vanillae, 
  L., 
  Pyrameis 
  huntera,

  C. 
  

   euhule 
  and 
  A. 
  vanillae 
  in 
  the 
  Galapagos 
  are 
  strikingly 
  modified 
  

   in 
  the 
  direction 
  of 
  small 
  size 
  and 
  dark 
  sufEused 
  coloration, 
  

   being 
  in 
  fact 
  well-marked 
  races 
  of 
  these 
  species. 
  The 
  romantic 
  

   island 
  of 
  Juan 
  Fernandez, 
  350 
  miles 
  from 
  the 
  coast 
  of 
  Chile, 
  

   is 
  the 
  last 
  that 
  we 
  shall 
  encounter 
  in 
  our 
  circuit 
  of 
  the 
  oceans, 
  

   and 
  Pyrameis 
  carye, 
  Hiibn., 
  which 
  I 
  found 
  there 
  in 
  March 
  1882, 
  

   appears 
  to 
  be 
  its 
  sole 
  butterfly 
  inhabitant. 
  

  

  We 
  have 
  already 
  seen 
  that 
  the 
  range 
  of 
  butterflies 
  north 
  and 
  

   south 
  is 
  fully 
  equal 
  to 
  that 
  of 
  flowering 
  plants, 
  and 
  there 
  is 
  

   little 
  doubt, 
  given 
  continuous 
  land 
  extending 
  as 
  far, 
  that 
  

   flowers 
  and 
  their 
  attendant 
  insects 
  would 
  be 
  found 
  at 
  the 
  

   North 
  Pole 
  itself. 
  As 
  it 
  is, 
  we 
  find 
  butterflies 
  of 
  several 
  species 
  

   maintaining 
  their 
  existence 
  beyond 
  the 
  80th 
  parallel 
  of 
  latitude 
  

   under 
  the 
  most 
  rigorous 
  conditions 
  of 
  climate, 
  requiring 
  at 
  

   least 
  two 
  or 
  three 
  of 
  the 
  brief 
  Hyperborean 
  summers 
  to 
  com-
