﻿in 
  area 
  than 
  Scotland, 
  has 
  fewer 
  than 
  thirty 
  species 
  of 
  butter- 
  

   flies, 
  including 
  two 
  or 
  three 
  remarkable 
  endemic 
  mountain 
  

   forms 
  of 
  Satyridae 
  formerly 
  referred 
  to 
  the 
  characteristic 
  

   Australian 
  genus 
  Xenica, 
  as 
  well 
  as 
  one 
  Pcqnlio 
  {viacleayanus, 
  

   Leach) 
  which 
  is 
  common 
  near 
  Hobart, 
  and 
  is 
  the 
  most 
  southern 
  

   representative 
  of 
  its 
  almost 
  world-wide 
  family. 
  

  

  In 
  Patagonia 
  we 
  find, 
  east 
  of 
  the 
  mountain 
  backbone 
  of 
  

   the 
  country, 
  a 
  barren 
  and 
  treeless 
  land 
  with 
  a 
  limited 
  Flora 
  

   and 
  a 
  rigorous 
  climate 
  for 
  its 
  latitude, 
  while 
  the 
  densely 
  

   forested 
  coast 
  facing 
  the 
  Pacific 
  Ocean 
  is 
  one 
  of 
  the 
  wettest 
  

   and 
  most 
  stormy 
  regions 
  in 
  the 
  whole 
  world. 
  Butterflies 
  

   are 
  therefore 
  very 
  poorly 
  represented, 
  C. 
  Berg 
  recording 
  only 
  

   fourteen 
  species 
  as 
  occurring 
  south 
  of 
  the 
  Rio 
  Negro 
  in 
  lat, 
  40°. 
  

   In 
  the 
  vicinity 
  of 
  Magellan's 
  Straits 
  some 
  half-dozen 
  species 
  

   have 
  been 
  found, 
  and 
  Colias 
  imperialis, 
  Butl., 
  one 
  of 
  the 
  finest 
  

   and 
  rarest 
  representatives 
  of 
  its 
  genus, 
  is 
  supposed, 
  though 
  

   with 
  some 
  doubt, 
  to 
  have 
  been 
  taken 
  by 
  Capt. 
  P. 
  P. 
  King, 
  R.N., 
  

   at 
  Port 
  Famine 
  about 
  the 
  year 
  1830. 
  When 
  I 
  was 
  at 
  Punta 
  

   Arenas 
  on 
  Christmas-day 
  1880, 
  I 
  found 
  the 
  grassy 
  park-like 
  

   country 
  near 
  the 
  settlement 
  enlivened 
  by 
  numbers 
  of 
  three 
  

   pretty 
  butterflies, 
  Colias 
  vautieri, 
  Guer. 
  (var. 
  cunninghami, 
  

   Butl.), 
  Pieris 
  {Tatochila) 
  argyrodice, 
  Stand., 
  and 
  BrentJiis 
  

   cytkeris, 
  Drury 
  ; 
  but 
  insect 
  life 
  of 
  any 
  kind 
  was 
  almost 
  absent 
  

   in 
  the 
  gloomy 
  and 
  Saturated 
  forests 
  of 
  the 
  Western 
  Patagonian 
  

   channels. 
  Mrs. 
  Scoresby 
  Routledge, 
  however, 
  in 
  her 
  adven- 
  

   turous 
  voyage 
  in 
  the 
  yacht 
  " 
  Mana 
  " 
  to 
  Easter 
  Island 
  in 
  1913, 
  

   occasionally 
  saw 
  butterflies 
  on 
  the 
  shores 
  of 
  the 
  Messier 
  Channel 
  

   in 
  lat. 
  49° 
  S. 
  In 
  Tierra 
  del 
  Fuego, 
  Darwin 
  says 
  that 
  he 
  " 
  saw 
  

   very 
  few 
  flies, 
  butterflies, 
  or 
  bees," 
  but 
  Tatochila 
  theodice, 
  

   Boisd., 
  T. 
  xanthodice, 
  Luc, 
  and 
  Brenthis 
  cytkeris 
  are 
  recorded 
  

   by 
  Mabille 
  from 
  Orange 
  Bay 
  in 
  Hoste 
  Island, 
  not 
  far 
  from 
  

   Cape 
  Horn 
  in 
  lat. 
  55° 
  30' 
  S., 
  and 
  these 
  are 
  almost 
  certainly 
  

   the 
  most 
  southern 
  of 
  all 
  known 
  butterflies. 
  

  

  Brenthis 
  cytkeris 
  is 
  also 
  reported 
  by 
  Mr. 
  R. 
  Vallentin 
  as 
  

   occurring 
  commonly 
  in 
  the 
  bleak 
  and 
  treeless 
  Falkland 
  Islands, 
  

   and 
  another 
  " 
  larger 
  and 
  faster 
  flying 
  Fritillary 
  with 
  more 
  

   pronounced 
  markings," 
  which 
  he 
  says 
  has 
  been 
  seen 
  in 
  West 
  

   Falkland, 
  is 
  almost 
  certainly 
  Danaida 
  plexij^pus 
  (race 
  erippiis, 
  

   Cram.) 
  which 
  has 
  wandered 
  hither 
  from 
  South 
  America,
