  In 
  1876, 
  the 
  species 
  was 
  further 
  described 
  by 
  Heinemann 
  and 
  

   Wocke 
  (Schmett. 
  Deutsch., 
  p. 
  797) 
  as 
  having 
  : 
  — 
  

  

  " 
  Forewings 
  brownish 
  yellow-grey, 
  dusted 
  with 
  white, 
  on 
  the 
  inner 
  margin 
  and 
  

   around 
  the 
  cleft 
  lighter 
  yellowish 
  ; 
  a 
  tiny 
  median 
  streak 
  ; 
  a 
  transverse 
  spot, 
  or 
  a 
  pair 
  

   of 
  dots, 
  just 
  before 
  the 
  cleft, 
  and 
  a 
  longitudinal 
  streak 
  in 
  the 
  upper 
  lobe 
  dark 
  brown 
  ; 
  

   behind 
  the 
  last 
  is 
  a 
  white 
  oblique 
  transverse 
  line 
  ; 
  fringes 
  around 
  the 
  apices 
  of 
  

   both 
  lobes 
  white. 
  4>-5 
  lin. 
  The 
  species 
  is 
  nearest 
  to 
  plagiodactylus, 
  but 
  differs 
  by 
  

   the 
  stunrpier 
  forewings 
  and 
  shorter 
  lobes. 
  The 
  spot 
  at 
  the 
  cleft 
  is 
  separated 
  from 
  

   the 
  latter 
  by 
  a 
  yellowish 
  space, 
  and 
  generally 
  consists 
  of 
  two 
  dots 
  standing 
  perpen- 
  

   dicularly 
  above 
  one 
  another. 
  The 
  longitudinal 
  spot 
  of 
  the 
  upper 
  lobe 
  only 
  reaches 
  

   to 
  the 
  pure 
  white, 
  strongly 
  marked, 
  transverse 
  line; 
  beyond 
  this 
  the 
  lobe 
  is 
  yellow- 
  

   brown, 
  strongly 
  dusted 
  with 
  white. 
  The 
  fringes 
  of 
  the 
  costa 
  white 
  above 
  the 
  spot 
  

   at 
  end 
  of 
  cleft, 
  brown 
  above 
  the 
  longitudinal 
  streak 
  of 
  the 
  upper 
  lobe 
  ; 
  the 
  outer 
  

   marginal 
  fringes 
  of 
  this 
  lobe 
  white, 
  with 
  a 
  dark 
  brown 
  border 
  ; 
  the 
  fringes 
  of 
  the 
  

   cleft 
  white, 
  on 
  the 
  inner 
  angle 
  of 
  the 
  upper 
  lobe, 
  and 
  at 
  the 
  apex 
  of 
  the 
  lower 
  lobe 
  

   brownish 
  ; 
  the 
  hindmarginal 
  fringes 
  of 
  the 
  latter 
  at 
  the 
  base 
  and 
  anal 
  angle 
  yellow- 
  

   ish, 
  at 
  the 
  apex 
  white, 
  also 
  with 
  brown 
  basal 
  line, 
  without 
  prominent 
  spots 
  ; 
  fringes 
  

   of 
  inner 
  margin 
  pale 
  yellow." 
  

  

  Two 
  years 
  later 
  (1878), 
  Zeller 
  referred 
  certain 
  north 
  German 
  

   specimens 
  to 
  this 
  species 
  (Stett. 
  Ent. 
  Ztg., 
  p. 
  164), 
  whilst, 
  in 
  1880, 
  

   Frey 
  appears 
  to 
  have 
  described 
  (Lep. 
  der 
  Schweiz, 
  p. 
  480) 
  the 
  species 
  

   under 
  two 
  names, 
  via., 
  the 
  type 
  or 
  mountain 
  form 
  as 
  plagiodactylus, 
  

   Sta., 
  and 
  the 
  lowland 
  form 
  as 
  graphodactylus, 
  unless, 
  indeed, 
  all 
  his 
  refer- 
  

   ences 
  to 
  the 
  former, 
  except 
  that 
  of 
  " 
  Zurich," 
  are 
  not 
  to 
  the 
  true 
  scabious- 
  

   feeding 
  plagiodactylus. 
  In 
  the 
  "Frey 
  coll." 
  the 
  specimens 
  under 
  both 
  

   names 
  are 
  all 
  apparently 
  pneumonanthes. 
  In 
  the 
  same 
  year, 
  Biittner 
  

   describes 
  (Stett. 
  Ent. 
  Ztg., 
  p. 
  472) 
  the 
  north 
  German 
  form 
  under 
  the 
  

   name 
  of 
  plagiodactylus, 
  or 
  pneumonanthes, 
  n.sp. 
  Snellen 
  also 
  appears 
  to 
  

   have 
  dealt 
  with 
  graphodactyla 
  var. 
  pneumonanthes, 
  under 
  the 
  name 
  of 
  

   plagiodactylus, 
  Sta. 
  (De 
  Vlind., 
  ii., 
  pt. 
  2, 
  p. 
  1037), 
  as 
  also 
  did 
  Snellen 
  

   van 
  Vollenhoven, 
  in 
  Sepp's 
  Ned. 
  his., 
  2nd 
  series, 
  vol. 
  iv., 
  pp. 
  188 
  et 
  seq., 
  

   pi. 
  xxxiv., 
  figs. 
  1-13, 
  where 
  he 
  gives 
  a 
  first-class 
  account 
  and 
  figures 
  

   of 
  the 
  species 
  under 
  the 
  latter 
  name. 
  Hering 
  insisted 
  (Stett. 
  Ent. 
  

   Ztg., 
  1891, 
  pp. 
  225-6 
  ; 
  1893, 
  pp. 
  117-120) 
  on 
  the 
  application 
  of 
  the 
  

   name 
  plagiodactylus, 
  Sta., 
  to 
  the 
  north 
  German 
  form. 
  He 
  says 
  (Stett. 
  

   Ent. 
  Ztg., 
  1891, 
  pp. 
  225-6) 
  that 
  "Biittner 
  has 
  queried 
  as 
  a 
  new 
  

   species, 
  pneumonanthes, 
  Schleich, 
  for 
  the 
  simple 
  reason 
  that 
  Snellen 
  

   (De 
  Vlind., 
  p. 
  1038) 
  has 
  pointed 
  out 
  that 
  there 
  is 
  not 
  yet 
  agreement 
  

   among 
  authors 
  with 
  regard 
  to 
  the 
  specific 
  characters 
  of 
  grapliodactylus, 
  

   Sorhagen 
  calling 
  the 
  form, 
  from 
  Gentiand 
  pneumonanthe, 
  graphodactylus, 
  

   Tr., 
  whilst 
  Biittner 
  calls 
  it 
  plagiodactylus." 
  He 
  adds 
  that 
  he 
  sent 
  

   specimens 
  (captured 
  in 
  August, 
  1888, 
  at 
  Finkenkrug) 
  to 
  Stainton 
  and 
  

   Wocke 
  ; 
  the 
  former, 
  he 
  says, 
  declared 
  them 
  to 
  be 
  his 
  plagiodactylus, 
  

   the 
  latter 
  graphodactylus. 
  He 
  goes 
  on 
  to 
  state 
  that 
  he 
  considers 
  the 
  

   north 
  German 
  examples 
  specifically 
  distinct 
  from 
  graphodactylus 
  that 
  

   he 
  has 
  received 
  from 
  Switzerland 
  and 
  Austria, 
  to 
  which 
  two 
  examples 
  

   from 
  Lombardy, 
  sent 
  by 
  Turati, 
  come 
  nearest. 
  He 
  then 
  adds 
  that 
  

   "Snellen 
  says 
  (De 
  Vlind., 
  p. 
  1088) 
  that, 
  in 
  bis 
  opinion, 
  'the 
  plagio- 
  

   dactylus 
  of 
  Zeller, 
  Frey, 
  and 
  Wocke, 
  all 
  belong 
  to 
  graphodactylus. 
  Tr., 
  

   or 
  are 
  mixed 
  up 
  therewith.' 
  Snellen 
  adds 
  that 
  'one 
  cannot 
  describe 
  

   the 
  forewings 
  of 
  plagiodactylus, 
  Sta., 
  as 
  brown. 
  They 
  are 
  coloured 
  almost 
  

   like 
  coprodactylus, 
  Sta., 
  but 
  of 
  a 
  darker 
  tint.' 
  Biittner 
  says 
  (in 
  a 
  

   footnote): 
  'It 
  appears 
  to 
  me 
  that 
  graphodactyla, 
  Tr., 
  and 
  plagiodactylus, 
  

   Sta. 
  (i.e., 
  var. 
  pneumonanthes), 
  are 
  not 
  specifically 
  distinct, 
  but 
  that 
  the 
  

   latter 
  is 
  a 
  blue-grey 
  variety 
  of 
  the 
  former.
