  it 
  '

  a 
  great 
  deal 
  in 
  its 
  fliglit, 
  it 
  

   is 
  more 
  difficult 
  to 
  catch 
  than 
  Colias. 
  These 
  butterflies 
  are 
  

   sometimes 
  seen 
  together, 
  however, 
  in 
  which 
  case 
  it 
  is 
  Argynnis 
  

   that 
  has 
  come 
  on 
  to 
  the 
  grounds 
  of 
  Colias, 
  and 
  they 
  playfully 
  

   cross 
  one 
  another 
  before 
  jDroceeding 
  on 
  their

  More 
  

   rarely 
  and 
  more 
  singly 
  we 
  meet 
  with 
  the 
  day-butterfly 
  Lycaena 
  

   orhitulus 
  on 
  localities 
  similar 
  to 
  those 
  of 
  Argynnis. 
  It 
  is 
  quite 
  

   imj)ossible 
  to 
  see 
  this 
  butterfly 
  when 
  sitting 
  on 
  the 
  ground; 
  

   the 
  gray 
  underside 
  of 
  the 
  folded 
  wings 
  blends 
  so 
  perfectly 
  with 
  

   the 
  surrounding 
  small 
  stones. 
  It 
  does 
  not 
  fly 
  far 
  each 
  time, 
  

   but 
  irregularly 
  and 
  fairly 
  quickly." 
  

  

  A 
  much 
  earlier 
  record 
  .of 
  butterflies 
  from 
  the 
  same 
  coast, 
  

   but 
  in 
  a 
  considerably 
  lower 
  latitude, 
  is 
  that 
  of 
  the 
  veteran 
  

   whaling 
  captain 
  William 
  Scoresby, 
  junior. 
  At 
  the 
  end 
  of 
  July 
  

   1822, 
  in 
  the 
  region 
  now 
  known 
  as 
  Scoresby 
  Sound 
  (lat. 
  70° 
  

   30' 
  N., 
  long. 
  22° 
  W.), 
  he 
  found 
  on 
  landing 
  that 
  " 
  the 
  insects 
  

   were 
  numerous, 
  consisting 
  of 
  mosquitoes, 
  and 
  several 
  species 
  

   of 
  butterflies." 
  These 
  latter 
  are 
  named 
  in 
  the 
  appendix 
  to 
  

   Scoresby's 
  narrative 
  of 
  his 
  voyage, 
  as 
  " 
  Papilio 
  palaeno, 
  L., 
  

   and 
  P. 
  dia, 
  L.," 
  by 
  Prof. 
  Jameson 
  of 
  Edinburgh. 
  Many 
  years 
  

   afterwards 
  (1899-1900) 
  this 
  part 
  of 
  the 
  Greenland 
  coast 
  was 
  

   visited 
  by 
  Prof. 
  A. 
  G. 
  Nathorst, 
  who 
  there 
  collected 
  specimens 
  

   of 
  the 
  four 
  butterflies 
  so 
  characteristic 
  of 
  these 
  high 
  latitudes, 
  

   Colias 
  hecla, 
  Brenthis 
  charidca, 
  B. 
  polaris, 
  and 
  Lycaena 
  orhitulus 
  

   var. 
  aquilo, 
  to 
  the 
  first 
  two 
  of 
  which 
  Scoresby's 
  insects 
  must 
  in 
  

   all 
  probability 
  be 
  referred. 
  No 
  butterfly 
  has 
  been 
  as 
  yet 
  

   recorded 
  from 
  Spitsbergen, 
  though 
  several 
  species 
  of 
  moths 
  are 
  

   known 
  from 
  this 
  archipelago. 
  

  

  Before 
  finally 
  leaving 
  the 
  North 
  Polar 
  basin, 
  the 
  case 
  of 
  

   Iceland 
  demands 
  attention. 
  As 
  many 
  as 
  six 
  species 
  of 
  butter- 
  

   flies, 
  belonging 
  to 
  the 
  characteristic 
  Arctic 
  genera 
  Colias, 
  

   Erehia, 
  and 
  Brenthis, 
  have 
  been 
  stated 
  by 
  various 
  writers 
  to 
  

   occur 
  in 
  this 
  large 
  island, 
  which 
  from 
  its 
  relatively 
  mild 
  climate 
  

   and 
  fairly 
  luxuriant 
  vegetation 
  might 
  reasonably 
  be 
  expected 
  

   to 
  produce 
  some 
  at 
  least 
  of 
  them. 
  But 
  of 
  late 
  years, 
  the 
  visits 
  

   of 
  several 
  able 
  entomologists 
  to 
  Iceland, 
  notably 
  the 
  long 
  stay 
  

   of 
  Dr. 
  Staudinger 
  in 
  1857, 
  have 
  not 
  revealed 
  the 
  presence 
  of 
  

   even 
  a 
  single 
  resident 
  species. 
  The 
  only 
  authentic 
  record 
  that 
  

   I 
  can 
  find 
  of 
  the 
  occurrence 
  of 
  any 
  butterfly 
  in 
  Iceland, 
  is
