  forewings, 
  the 
  blacker, 
  more 
  conspicuous, 
  dots, 
  and 
  the 
  brown-grey 
  

   hindwings. 
  It 
  differs 
  from 
  vars. 
  c 
  and 
  d 
  by 
  its 
  larger 
  size, 
  less 
  dark 
  

   and 
  dull 
  ground-colour, 
  by 
  the 
  edging 
  of 
  the 
  costa 
  extending 
  further 
  

   towards 
  the 
  wing-base, 
  by 
  the 
  marking 
  of 
  the 
  fringes 
  of 
  the 
  lobes, 
  the 
  

   upper 
  one 
  having 
  one 
  sharply 
  denned 
  black 
  spot 
  at 
  the 
  inner 
  angle, 
  

   and 
  the 
  lower 
  one 
  two 
  such 
  spots, 
  one 
  of 
  which 
  is 
  at 
  the 
  apical 
  point, 
  

   and 
  the 
  other 
  below 
  it, 
  whilst 
  in 
  the 
  var. 
  in 
  question, 
  there 
  is, 
  on 
  the 
  

   front 
  lobe, 
  a 
  somewhat 
  distinct 
  brown 
  spot, 
  elongated 
  towards 
  the 
  

   apex, 
  and 
  which 
  has 
  not 
  infrequently, 
  behind 
  the 
  extension, 
  a 
  tiny 
  

   dot 
  ; 
  the 
  apex 
  of 
  the 
  lower 
  lobe 
  is 
  surrounded 
  by 
  a 
  brown 
  line, 
  which 
  

   thickens 
  somewhat 
  at 
  the 
  points 
  where 
  vars. 
  a

  have 
  spots. 
  

   Finally, 
  vars.

  not 
  the 
  light, 
  greyish, 
  transverse 
  line 
  so 
  

   frequent 
  in

  the 
  black 
  scattered 
  scales 
  forming 
  the 
  longitudinal 
  

   dash 
  in 
  the 
  upper 
  lobe, 
  being 
  more 
  or 
  less 
  numerous 
  and 
  mixed 
  with 
  

   white 
  ones, 
  so 
  that 
  the

  is 
  sometimes 
  very 
  inconspicuous 
  and 
  

   incomplete."

  This 
  species 
  is 
  to 
  be 
  found 
  in 
  

   Scania 
  (the 
  southernmost 
  part 
  of 
  Sweden), 
  but 
  is 
  much 
  more 
  scarce 
  than 
  the 
  

   previous 
  species, 
  at 
  the 
  end 
  of 
  July 
  and 
  in 
  the 
  beginning 
  of 
  August, 
  and 
  haunts 
  

   only 
  damp 
  meadows 
  and 
  mosses. 
  Its 
  later 
  time 
  of 
  appearance, 
  different 
  habitat, 
  

   and 
  the 
  difference 
  in 
  the 
  coloration, 
  as 
  well 
  as 
  its 
  smaller 
  size, 
  make 
  us 
  consider 
  

   it 
  to 
  be 
  specifically 
  different 
  from 
  the 
  previous 
  species, 
  with 
  which 
  it 
  has 
  (with 
  

   reservation) 
  been 
  united 
  by 
  Zeller. 
  It 
  is 
  considerably 
  smaller 
  than 
  the 
  preceding 
  

   species, 
  and 
  the 
  forewings 
  are 
  grey-brown, 
  or 
  more 
  slaty-grey 
  than 
  pterodactyla, 
  

   which 
  it 
  otherwise 
  resembles 
  very 
  much. 
  It 
  has 
  often, 
  like 
  the 
  latter, 
  a 
  light 
  grey 
  

   transverse 
  line 
  across 
  the 
  upper 
  lobe 
  of 
  the 
  forewings, 
  which, 
  however, 
  does 
  not 
  

   reach 
  the 
  fringes 
  of 
  the 
  front 
  edge, 
  and 
  consists 
  of 
  scattered 
  scales. 
  There 
  is 
  also 
  

   often 
  an 
  indistinct 
  brownish 
  vertical 
  streak. 
  In 
  the 
  anal 
  angle 
  of 
  the 
  upper 
  lobe 
  

   of 
  the 
  forewings, 
  there 
  are 
  also 
  to 
  be 
  found, 
  in 
  the 
  cilia, 
  one 
  or 
  two 
  indistinct 
  blackish 
  

   spots, 
  but, 
  on 
  the 
  lower 
  lobe, 
  there 
  are 
  no 
  signs 
  of 
  spots, 
  their 
  place 
  being 
  taken 
  by 
  an 
  

   obscure 
  brown 
  line 
  passing 
  round 
  the 
  apex 
  at 
  the 
  base 
  of 
  the 
  cilia. 
  As 
  regards 
  the 
  

   ground 
  colour 
  of 
  the 
  forewings, 
  it 
  resembles 
  very 
  much 
  that 
  of 
  M. 
  serotinus 
  

   (bipunctidactyla), 
  but 
  is 
  easily 
  differentiated 
  by 
  the 
  narrow 
  white 
  line 
  on 
  the 
  

   front 
  edge 
  (Wallengren). 
  

  

  Hofmann 
  observes 
  (Die 
  deutsch. 
  Pteroph., 
  p. 
  85) 
  that 
  " 
  6. 
  paludi- 
  

   cola, 
  Wallgrn., 
  is 
  a 
  variety 
  of 
  S. 
  fusca 
  ; 
  Zeller 
  has 
  described 
  it 
  as 
  fusca, 
  

   vars. 
  c 
  et 
  d 
  (Linn. 
  Ent., 
  vi., 
  p. 
  371). 
  This 
  form, 
  which 
  appears 
  to 
  differ 
  

   solely 
  in 
  the 
  somewhat 
  darker 
  coloration, 
  and 
  in 
  the 
  presence 
  of 
  an 
  

   indistinct 
  brown 
  line 
  running 
  round 
  the 
  apex 
  of 
  the 
  lower 
  lobe 
  at 
  the
