  but 
  a 
  variety 
  of 
  this 
  species. 
  He 
  further 
  noted 
  that, 
  in 
  the 
  

   course 
  of 
  the 
  year, 
  he 
  had 
  reared 
  a 
  hundred 
  cosmodactyla, 
  Tr., 
  

   from 
  the 
  seed-capsules 
  of 
  Aquilegia, 
  among 
  which 
  was 
  a 
  single 
  

   specimen 
  identical 
  with 
  those 
  reared 
  from 
  Stachys 
  sylvatica. 
  It 
  

   is 
  to 
  be 
  assumed, 
  therefore, 
  that 
  the 
  olive-brown 
  form 
  is 
  Frey's 
  stachy- 
  

   dalis, 
  an 
  assumption 
  borne 
  out 
  by 
  the 
  types 
  in 
  his 
  own 
  collection 
  at 
  the 
  

   British 
  Museum. 
  It 
  is 
  the 
  nearest 
  of 
  all 
  the 
  forms 
  to 
  our 
  ordinary 
  

   British 
  punctidactyla, 
  and, 
  except 
  for 
  being, 
  perhaps, 
  a 
  little 
  yellower 
  

   and 
  brighter-tinted, 
  would 
  fall 
  within 
  the 
  bounds 
  of 
  punctidactyla, 
  

   Haw., 
  very 
  well. 
  Boll, 
  himself, 
  records 
  breeding 
  pale 
  olive-brown 
  speci- 
  

   mens 
  at 
  Bremgarten. 
  Stainton 
  quoted 
  Frey's 
  remarks 
  (Ent. 
  Mo. 
  Mag., 
  

   xviii., 
  p. 
  213) 
  ; 
  and 
  Hofmann 
  observes 
  (Pter. 
  Deutsch., 
  p. 
  66) 
  that 
  " 
  the 
  

   var. 
  stachydalis 
  varies 
  from 
  the 
  type, 
  principally 
  in 
  the 
  unusually 
  rich 
  

   yellowish-white 
  and 
  greenish-yellow 
  scaling, 
  which 
  makes 
  this 
  particular 
  

   form 
  look 
  very 
  much 
  lighter, 
  sometimes 
  yellowish-white; 
  the 
  markings, 
  

   however, 
  being 
  the 
  same 
  as 
  " 
  the 
  type." 
  It 
  is 
  impossible 
  to 
  accept 
  

   South's 
  acanthodactyla 
  var. 
  a 
  (see 
  Ent., 
  xxii., 
  pp. 
  31-32) 
  as 
  this 
  form, 
  

   although 
  it 
  has 
  been 
  referred 
  hereto, 
  its 
  ground 
  colour 
  of 
  " 
  ochreous- 
  

   grey, 
  with 
  a 
  rosy 
  tinge," 
  not 
  satisfying 
  Frey's 
  description 
  of 
  " 
  bright 
  

   olive-brown 
  " 
  (see 
  antea, 
  p. 
  176). 
  Treitschke's 
  cosmodactyla 
  is 
  perhaps 
  

   stachydalis, 
  Frey, 
  Treitschke's 
  insect 
  being 
  described 
  as 
  "Alucita, 
  alis 
  

   anticis 
  olivaceo-fuscis, 
  macula 
  triangulari 
  obscuriore, 
  punctis 
  costalibus 
  

   albis." 
  The 
  specimens 
  described 
  by 
  Treitschke 
  came 
  from 
  Schmidt, 
  and 
  

   were 
  taken 
  at 
  Laybach 
  ; 
  he 
  further 
  adds 
  that 
  ' 
  ' 
  the 
  Hiibnerian 
  cosmodac- 
  

   tyla 
  accords 
  exactly 
  with 
  it." 
  We 
  can 
  only 
  suppose 
  that 
  there 
  must 
  be 
  

   great 
  difference 
  in 
  the 
  Hubnerian 
  figures, 
  certainly 
  those 
  we 
  have 
  seen 
  

   show 
  no 
  trace 
  of 
  olive 
  in 
  them 
  (see 
  antea, 
  pp. 
  274-5).

  This, 
  we 
  suspect, 
  to 
  be 
  the

  the

   Judging 
  by 
  the

  the

  specimens 
  are 
  almost 
  

   entirely 
  of 
  this 
  form, 
  in 
  extremely 
  varying 
  examples. 
  Specimens 
  

   from

  are 
  also 
  in

  Museum

  The 
  only 
  

   British 
  examples 
  of 
  this

  that 
  we

  were

  Comparison 
  of 
  Amblyptilia 
  punctidactyla 
  and 
  A. 
  cosmodactyla. 
  — 
  

   Amblyptilia 
  punctidactyla 
  is 
  a 
  somewhat 
  stouter 
  form 
  with 
  broader 
  

   wings 
  than 
  its 
  near 
  ally; 
  the 
  forewings 
  are 
  very 
  richly 
  dusted 
  with 
  

   yellow 
  and 
  white, 
  or 
  sometimes 
  with 
  greenish-yellow 
  on 
  a 
  blackish 
  

   ground, 
  so 
  that 
  they 
  appear 
  as 
  if 
  marbled. 
  The 
  white 
  spots 
  of 
  the 
  

   costa 
  are 
  larger 
  than 
  in 
  A. 
  cosmodactyla. 
  The 
  underside 
  of 
  the 
  lore 
  

   wings 
  uniform 
  black, 
  with 
  deep 
  black 
  costa 
  sen 
  with 
  largo 
  white 
  spots. 
  

   while 
  the 
  costa 
  in 
  A. 
  cosmodactyla 
  is 
  always 
  brown. 
  The 
  underside 
  of 
  

   the 
  1st 
  and 
  3rd 
  plumules 
  of 
  the 
  hindwings 
  black 
  (in 
  ./. 
  cosmodactyla 
  

   brown), 
  richly 
  sprinkled 
  with 
  white 
  scales. 
  The 
  scale- 
  tuft 
  of 
  the 
  

   3rd 
  plumule 
  is 
  (like 
  the 
  very 
  weak 
  indication 
  of 
  t 
  ho 
  anal 
  angle)
