  Expanse

  lines. 
  So 
  much 
  suffused 
  with 
  an 
  

   umber 
  tint 
  as 
  to 
  appear 
  almost 
  entirely 
  of 
  this 
  colour, 
  but 
  the 
  whitish 
  ground 
  colour 
  

   shows 
  itself 
  along 
  the 
  inner 
  margin, 
  and 
  again 
  in 
  a 
  narrow 
  ill-defined 
  stripe 
  from 
  

   the 
  costa 
  to 
  the 
  digital 
  juncture 
  ; 
  the 
  scales 
  at 
  the 
  digital 
  juncture 
  hardly 
  darker. 
  

   All 
  three 
  feathers 
  of 
  the 
  hindwings, 
  including 
  the 
  fringes, 
  are 
  lustrous 
  umber-brown, 
  

   and 
  there 
  is 
  no 
  trace 
  of 
  darker 
  scales 
  along 
  the 
  inner 
  margin 
  of 
  the 
  3rd 
  feather. 
  The 
  

   tibiae 
  of 
  hindlegs 
  whitish 
  to 
  their 
  middle, 
  then 
  brownish 
  to 
  the 
  tarsi 
  ; 
  the 
  tarsi 
  are 
  

   whitish, 
  and 
  have 
  three 
  narrow 
  brownish 
  rings. 
  Imago 
  emerged 
  July 
  21st, 
  1885, 
  

   from 
  larva 
  sent 
  from 
  Tillicoultry, 
  June 
  24th. 
  The 
  halfgrown 
  larvae 
  examined 
  

   differed 
  from 
  a 
  fullgrown 
  one, 
  in 
  that 
  the 
  dorsal 
  and 
  subdorsal 
  stripes 
  somewhat 
  

   approached 
  purple-brown. 
  The 
  fullgrown 
  larva 
  did 
  not 
  differ 
  from 
  that 
  of 
  dichro- 
  

   dactylus 
  (already 
  described 
  from 
  tansy, 
  Ent., 
  xv., 
  p. 
  146) 
  except 
  that 
  the 
  prolegs 
  

   and 
  anal 
  claspers 
  of 
  the 
  yarrow-feeding 
  larva 
  were 
  tipped 
  with 
  black 
  instead 
  of 
  

   broAvn 
  ; 
  the 
  position, 
  appearance, 
  and 
  hirsute 
  adornment 
  of 
  the 
  tubercles 
  were 
  

   identical. 
  The 
  pupa 
  agreed 
  exactly 
  with 
  the 
  description 
  of 
  that 
  of 
  dichro 
  dactylics 
  

   (loc. 
  cit.) 
  (South). 
  

  

  This 
  dark 
  form 
  is 
  merely 
  the 
  extreme 
  brownish-ochreous 
  aberration 
  

   that 
  the 
  species 
  reaches 
  in 
  Scotland. 
  Its 
  uniform 
  appearance 
  prives 
  it 
  a 
  

   very 
  distinct 
  facies, 
  and 
  the 
  strong 
  development 
  of 
  its 
  discal 
  points 
  and 
  

   deep 
  colour 
  combined, 
  suggest 
  somewhat 
  Stenoptilia 
  pterodactyla, 
  but 
  

   not, 
  of 
  course, 
  in 
  any 
  critical 
  detail. 
  The 
  best 
  we 
  have 
  seen 
  were 
  taken 
  

   by 
  Dalglish 
  at 
  Mauchline, 
  July, 
  1892, 
  and 
  are 
  almost 
  uniformly 
  brown. 
  

   These 
  extremes 
  are 
  found 
  with 
  ab. 
  intermedia 
  in 
  the 
  north, 
  the 
  latter 
  

   not 
  being 
  an 
  unusual 
  form 
  in 
  our 
  best 
  coloured 
  English 
  specimens. 
  

  

  The 
  American 
  forms 
  of 
  this 
  species 
  have 
  been

  — 
  The 
  brown-bordered 
  plume 
  (P. 
  margini- 
  

   dactylus). 
  Tawny-brown, 
  the 
  forewings 
  varied 
  with 
  white 
  cloud-like 
  spots, 
  whereof 
  

   there 
  is 
  one 
  on 
  the 
  outer 
  margin 
  towards 
  the 
  tip, 
  and 
  two 
  on 
  the 
  inner 
  margin 
  ; 
  the 
  

   apical 
  and 
  outer 
  margins 
  and 
  a 
  cloud-like 
  central 
  space 
  extending 
  from 
  the 
  cleft 
  

   inwards, 
  are 
  of 
  a 
  dark 
  brown 
  colour 
  ; 
  fringes 
  whitish, 
  brown 
  at 
  the 
  outer 
  and 
  inner 
  

   apical 
  angles, 
  and 
  a 
  small 
  brown 
  spot 
  beyond 
  the 
  middle 
  of 
  the 
  inner 
  margin 
  ; 
  

   underside 
  and 
  hindwings 
  pale 
  tawny-brown 
  ; 
  legs 
  white 
  ; 
  thighs, 
  anterior 
  shanks, 
  

   and 
  apical 
  third 
  of 
  the 
  hind 
  shanks, 
  brownish 
  on 
  their 
  outer 
  sides. 
  Wings 
  expand 
  

   1 
  in. 
  Occurs 
  the 
  latter 
  part 
  of 
  June, 
  on 
  weeds 
  growing 
  along 
  the 
  borders 
  of 
  

   meadows 
  (Fitch).

  nebidaedactylus, 
  Fitch, 
  "New

  Rept.," 
  i., 
  p. 
  849 
  (1854).— 
  The 
  cloudy 
  

   plume 
  (P. 
  nebidaedactylus) 
  . 
  Milky-white, 
  the 
  forewings 
  clouded 
  with 
  pale 
  tawny- 
  

   brown, 
  which 
  colour 
  occupies 
  the 
  basal 
  portion, 
  and 
  forms 
  two 
  broad 
  bands 
  towards 
  

   the 
  apex, 
  the 
  last 
  one 
  often 
  faint 
  and 
  not 
  perceptible 
  on 
  the 
  inner 
  lobe 
  ; 
  hindwings 
  

   and 
  their 
  fringes, 
  and 
  the 
  underside 
  of 
  both 
  pairs, 
  of 
  the 
  same 
  pale 
  tawny-brown 
  colour; 
  

   abdomen 
  white, 
  sides 
  and 
  stripe 
  on 
  the 
  middle 
  of 
  the 
  back 
  pale 
  tawny-brown 
  ; 
  legs 
  

   white. 
  Wings 
  expand 
  1 
  in. 
  The 
  tawny 
  marks 
  on 
  the 
  forewings 
  are 
  often 
  obscure 
  

   in 
  old 
  individuals, 
  and 
  sometimes 
  wholly 
  obliterated 
  ; 
  still 
  the 
  species 
  may 
  be 
  

   discriminated 
  by 
  the 
  pale 
  tawny 
  colour 
  of 
  the 
  hindwings, 
  and 
  the 
  under 
  surface 
  of 
  

   the 
  fore 
  ones 
  contrasting 
  with 
  the 
  whiteness 
  of 
  their 
  upper 
  surface. 
  It 
  is 
  our 
  most 
  

   common 
  species, 
  occurring 
  from 
  the 
  middle 
  of 
  June 
  till 
  the 
  middle 
  of 
  July, 
  in 
  yards 
  

   around 
  dwellings, 
  frequently 
  entering 
  open 
  windows 
  in 
  the 
  evening, 
  being 
  

   attracted 
  by 
  the 
  light 
  of 
  the 
  lamps 
  (Fitch).

  — 
  Seven 
  j 
  specimens, 
  some 
  in 
  very 
  poor 
  condition, 
  from 
  

   various 
  parts 
  of 
  North 
  America, 
  which 
  Schlagor 
  called 
  bischoiji. 
  They 
  fully 
  agree 
  

   in 
  the 
  colouring 
  of 
  the 
  wings 
  and 
  legs 
  with 
  bertrami, 
  the 
  principal 
  difference 
  being 
  

   in 
  the 
  hindlegs, 
  which, 
  in 
  the 
  best 
  examples, 
  are 
  quite 
  plain 
  and 
  unicoloured, 
  whilst 
  

   in 
  ochrodactyla 
  and 
  bertrami 
  there 
  is, 
  at 
  least 
  at 
  the 
  tip 
  of 
  the 
  first 
  joint, 
  a 
  brown 
  

   spot; 
  the 
  best 
  examples, 
  too, 
  have 
  the 
  apex 
  of 
  the 
  first 
  lobe 
  somewhat 
  shorter, 
  

   broader 
  and 
  less 
  pointed 
  than 
  in 
  these 
  species 
  (Zellor). 
  

  

  Later, 
  Zeller 
  wrote 
  that 
  it 
  was 
  nearest 
  to 
  bertrami, 
  not 
  only 
  by 
  the
