  Guenee's 
  remarks 
  on 
  the 
  variation 
  in 
  atomaria 
  (1857), 
  " 
  Sp. 
  

   Gen. 
  Lep.," 
  Vol. 
  II., 
  p. 
  154 
  are 
  that 
  he 
  was 
  unable 
  to 
  establish 
  

   races 
  ; 
  intermediates 
  were 
  so 
  abundant 
  as 
  absolutely 
  to 
  preclude 
  

   such 
  a 
  treatment. 
  He 
  however 
  notes 
  that 
  examples 
  from 
  the 
  

   mountains 
  -were 
  small 
  and 
  white. 
  

  

  I 
  suggest 
  that 
  his 
  knowledge 
  of 
  atomaria 
  was 
  very 
  limited, 
  and 
  

   that 
  his 
  last 
  statement 
  requires 
  a 
  qualification. 
  In 
  neither 
  Zeller's, 
  

   Frey's, 
  Leech's, 
  nor 
  Tutt's 
  collection 
  containing 
  specimens 
  of 
  

   mountain 
  races 
  are 
  there 
  any 
  such 
  small 
  and 
  white 
  female 
  

   examples 
  as 
  are 
  so 
  easily 
  obtainable 
  and 
  prevalent 
  in 
  Britain. 
  

  

  Lines 
  of 
  Variation. 
  

  

  In 
  1901, 
  C. 
  G. 
  Barrett 
  (" 
  Lep. 
  Brit. 
  Isles," 
  Vol. 
  VII., 
  p. 
  8) 
  sums 
  

   up 
  the 
  lines 
  of 
  the 
  more 
  prevalent 
  form 
  of 
  aberration 
  in 
  British 
  

   examples 
  as 
  follows 
  : 
  — 
  

  

  In 
  the 
  males 
  : 
  ground 
  colour 
  typically 
  yellow 
  and 
  brown, 
  

   varying 
  from 
  a 
  paucity 
  of 
  brown 
  dusting 
  to 
  almost 
  black-brown 
  

   from 
  the 
  intensity 
  of 
  the 
  dusting, 
  and 
  further 
  to 
  a 
  smooth 
  even 
  dull 
  

   black 
  without 
  speckling. 
  

  

  Bands, 
  colour 
  typically 
  deep 
  brown, 
  4 
  on 
  the 
  forewings 
  and 
  

   3 
  on 
  the 
  hindwings 
  with 
  a 
  wide 
  similarly 
  coloured 
  hind 
  marginal 
  

   band 
  on 
  both 
  wings. 
  These 
  vary 
  extremely 
  in 
  width, 
  definition, 
  

   shade 
  of 
  brown, 
  and 
  coalescence. 
  The 
  2nd 
  and 
  3rd 
  are 
  often 
  

   coalesced 
  from 
  the 
  discal 
  area 
  to 
  the 
  dorsal 
  margin, 
  the 
  point 
  of 
  

   junction 
  being 
  at 
  all 
  distances 
  from 
  the 
  margin. 
  The 
  4th 
  and 
  

   marginal 
  band 
  are 
  very 
  frequently 
  coalescent, 
  so 
  that 
  either 
  only 
  a 
  

   few 
  or 
  no 
  traces 
  of 
  the 
  intermediate 
  ground 
  space 
  remain. 
  

  

  In 
  the 
  females 
  : 
  ground, 
  never 
  unicolorous 
  dark. 
  Transverse 
  

   lines 
  practically 
  always 
  present. 
  Degree 
  of 
  dusting 
  very 
  variable, 
  

   from 
  nearly 
  destitute 
  of 
  speckling 
  through 
  every 
  degree 
  of 
  duskiness 
  

   to 
  a 
  dusky 
  white 
  appearance. 
  

  

  Barrett 
  (I.e.), 
  who 
  had 
  unprecedented 
  opportunities 
  for 
  the 
  

   examination 
  of 
  aberrations 
  existing 
  in 
  the 
  various 
  private 
  collections 
  

   throughout 
  the 
  country, 
  gives 
  the 
  following 
  summarised 
  list 
  : 
  — 
  

  

  Males.

  stripes 
  very 
  faint. 
  

  

  3. 
  Orange- 
  brown, 
  markings 
  absent 
  except 
  at 
  outer 
  margin, 
  

   dusted

  4. 
  Dark 
  stripes 
  very 
  broad. 
  

  

  5. 
  Wholly 
  smooth 
  pale 
  ochreous 
  buff, 
  no 
  trace 
  of 
  markings. 
  

  

  6. 
  Unicolorous 
  dark 
  brown. 
  

  

  7. 
  "Wholly

  each 
  forewing. 
  

  

  Females. 
  —
