  a 
  broad 
  brown 
  dash 
  in 
  place 
  of 
  the 
  

   costal 
  triangle 
  of 
  the 
  forewing, 
  a 
  bright 
  elongate 
  dash 
  before 
  the 
  cloud 
  of 
  

   the 
  lower 
  lobe 
  (indicated 
  in 
  calodactyla), 
  the 
  thick 
  yellowish 
  transverse 
  

   lines

  the

  the 
  want 
  of 
  black 
  scales 
  on 
  the 
  margin 
  of 
  the 
  

   third 
  plumule

  the 
  hindwings, 
  the 
  shortness 
  of 
  the

   Zeller 
  surmises 
  further 
  that 
  Kuhlwein 
  supplied 
  Hiibner 
  with 
  his 
  

   petradactyla 
  from 
  the 
  Riesengebirge. 
  Herrich-Schaffer 
  observes 
  (Sys. 
  

   Bearb., 
  v., 
  p. 
  368) 
  that 
  Hubner's 
  figures 
  of 
  petradactyla 
  are 
  small 
  

   examples 
  of 
  this 
  species 
  from 
  Silesia, 
  and 
  were, 
  he 
  adds, 
  in 
  Geyer's 
  

   collection. 
  The 
  figures, 
  he 
  says, 
  are 
  sufficing 
  but 
  poor, 
  the 
  terminal 
  

   portion 
  of 
  the 
  fringes 
  on 
  the 
  forewings 
  not 
  white 
  enough, 
  the 
  inner 
  

   margin 
  not 
  sufficiently 
  sharply 
  defined, 
  the 
  tooth 
  on 
  the 
  outer 
  margin 
  

   of 
  the 
  third 
  plumule 
  of 
  the 
  hindwings 
  absent.

  Expanse

  lines. 
  Forewing, 
  ground 
  colour 
  pale 
  ochreous-brown, 
  

   dusted 
  with 
  darker 
  brown 
  scales 
  ; 
  a 
  narrow 
  dark 
  chocolate 
  line 
  edges 
  the 
  

   costa, 
  and 
  a 
  dark 
  chocolate-brown 
  stripe 
  runs 
  along 
  the 
  inner 
  margin 
  ; 
  this 
  

   latter 
  is 
  interrupted 
  or 
  broken 
  by 
  three 
  blotches, 
  rather 
  paler 
  than 
  the 
  ground 
  colour, 
  

   one 
  at 
  the 
  base, 
  one 
  in 
  the 
  middle, 
  and 
  one 
  between 
  this 
  and 
  the 
  angle 
  of 
  inner 
  

   digit 
  ; 
  there 
  are 
  three 
  conspicuous 
  dark 
  chocolate-brown 
  marks 
  ; 
  the 
  first, 
  some- 
  

   what 
  triangular 
  in 
  shape, 
  has 
  its 
  base 
  on 
  the 
  costa 
  just 
  beyond 
  the 
  middle, 
  and 
  its 
  

   apex 
  in 
  close 
  proximity 
  to 
  the 
  digital 
  juncture; 
  the 
  inner 
  half 
  of 
  this 
  triangle 
  is 
  

   much 
  darker 
  than 
  the 
  costal 
  half, 
  and 
  its 
  posterior 
  edge 
  is 
  distinctly 
  edged 
  with 
  

   whitish, 
  especially 
  so 
  on 
  the 
  costa 
  ; 
  beyond 
  this 
  the 
  second 
  and 
  third 
  marks 
  

   represent 
  a 
  broadish 
  fascia, 
  interrupted 
  by 
  the 
  fissure 
  ; 
  its 
  posterior 
  edge 
  is 
  sharply 
  

   defined 
  by 
  a 
  whitish 
  line 
  running 
  parallel 
  with 
  the 
  hind 
  margin 
  ; 
  fringes 
  black, 
  

   streaked 
  along 
  the 
  inner 
  margins 
  with 
  white. 
  Tip 
  of 
  outer 
  digit

  pointed. 
  

   Hindwings 
  dark 
  grey-brown, 
  with 
  only 
  slightly 
  paler 
  fringes, 
  except 
  third 
  feather, 
  

   which 
  has 
  an 
  elongate 
  patch 
  of 
  black 
  scales 
  in 
  the 
  middle, 
  and 
  between 
  this 
  and 
  

   the 
  base 
  of 
  feather, 
  whitish 
  cilia. 
  Head 
  and

  North 
  Devon, 
  three 
  examples; 
  other 
  examples 
  in 
  Doubleday 
  

   collection 
  under 
  name 
  of 
  zetterstedtii. 
  The 
  species 
  may 
  be 
  at 
  once 
  separated 
  from 
  

   the 
  last-named 
  species 
  by 
  its 
  narrow 
  wings, 
  the 
  structural 
  character 
  of 
  which 
  

   would 
  seem 
  to 
  indicate 
  its 
  belonging 
  to 
  the 
  subgenus 
  Amblyptilia 
  . 
  The 
  ground 
  

   colour 
  and 
  markings 
  certainly 
  favour 
  zetterstedtii, 
  but 
  only 
  superficially, 
  for, 
  on 
  

   comparison, 
  the 
  dark 
  brown 
  digital 
  fascia 
  and 
  black 
  cilia 
  sufficiently 
  establish 
  its 
  

   claim 
  to 
  rank 
  as 
  a 
  distinct 
  species 
  (South). 
  

  

  Leech 
  says 
  that 
  this 
  aberration 
  occurs 
  in 
  June 
  and 
  July 
  at 
  Lynmouth 
  ; 
  

   it 
  flies 
  at 
  dusk 
  ; 
  and 
  differs 
  from 
  the 
  type 
  by 
  the 
  narrower 
  wings, 
  the 
  

   darker 
  brown 
  digital 
  fascia, 
  and 
  the 
  black 
  cilia. 
  We 
  do 
  not 
  observe 
  

   the 
  narrowness 
  of 
  the 
  wings, 
  but 
  the 
  darker 
  brown 
  digital 
  fasciae, 
  the 
  

   darker 
  (not 
  black) 
  fringes, 
  the 
  suffusion 
  of 
  the 
  ground 
  colour, 
  and 
  other 
  

   details, 
  are 
  very 
  characteristic 
  of 
  the 
  majority 
  of 
  our 
  darker 
  British 
  

   specimens.

  From

   first 
  heard

  , 
  last

  which 
  zetterstedtii 
  may 
  be 
  separated 
  from

  it 
  to 
  

   belong 
  to 
  the 
  former, 
  though 
  it 
  differs 
  from 
  that

  larger 
  si/.e

   different
