  in 
  Ersch 
  and 
  Grubers 
  Allyemeine 
  

   Encyclopadie, 
  iii., 
  p. 
  274 
  (1819), 
  cites 
  only 
  pentadactyla, 
  Linn.=ir£- 
  

   dactyla, 
  Scop., 
  as 
  an 
  example 
  of 
  the 
  genus. 
  In 
  1821, 
  Oken 
  alters 
  

   (Nat. 
  Schulen, 
  ii., 
  p. 
  177) 
  the 
  genus 
  Alucita 
  to 
  Pterophorus, 
  without 
  

   assigning 
  any 
  reason 
  for 
  the 
  change, 
  and 
  cites 
  pentadactylus 
  to 
  the 
  

   genus. 
  In 
  the 
  same 
  year, 
  Charpentier 
  compared 
  the 
  plumes 
  in 
  the 
  

   Vienna 
  collection 
  with 
  the 
  descriptions 
  in 
  the 
  Syst. 
  Verzeichniss 
  of 
  

   Schiffermuller, 
  and 
  a 
  series 
  of 
  footnotes 
  has 
  been 
  made 
  by 
  Zincken 
  

   as 
  to 
  his 
  determinations. 
  He 
  states 
  (Die 
  Z'unsler, 
  Wickler, 
  etc., 
  

   pp. 
  174 
  et 
  seq.) 
  that 
  the 
  calodactyla, 
  rlwdodactyla, 
  pterodactyla, 
  leuco- 
  

   dactyla* 
  , 
  meyadactylaf, 
  ochrodactyla, 
  mictodactyla, 
  ualactodactyla\, 
  and 
  

   hexadactyla 
  in 
  the 
  SchirTermiillerian 
  collection 
  are 
  quite 
  accurately 
  

   figured 
  under 
  these 
  names, 
  by 
  Hiibner, 
  and 
  may 
  be 
  considered 
  as 
  

   determining 
  the 
  Syst. 
  Verz. 
  species 
  bearing 
  these 
  names, 
  except 
  in 
  the 
  

   case 
  of 
  megadactyla 
  which 
  disagrees 
  with 
  SchitTermiiller's 
  original 
  

   description, 
  supported 
  largely 
  by 
  that 
  made 
  from 
  it 
  by 
  Fabricius. 
  He 
  

   further 
  notes 
  that 
  pentadactyla 
  was 
  absent 
  from 
  the 
  collection, 
  that 
  

   didactylai 
  (S.V., 
  p. 
  145, 
  no. 
  2) 
  perfectly 
  agreed 
  with 
  chrysodactyla 
  (S.V.,

  r 
  A. 
  leucodactyla 
  is 
  the 
  tetradactyla 
  of 
  Linne, 
  and 
  must 
  fall 
  before 
  the 
  older 
  

   name 
  (Zincken). 
  This 
  is 
  our 
  opinion, 
  the 
  foodplant 
  being 
  wrongly 
  cited 
  as 
  

   Pulmonaria 
  officinalis. 
  

  

  f 
  A. 
  megadactyla, 
  S.Y., 
  is 
  the 
  tesseradactyla 
  of 
  Linne, 
  and 
  when 
  he 
  says 
  the 
  

   hindwings 
  are 
  divided 
  into 
  4 
  plumules, 
  it 
  is 
  an 
  oversight 
  of 
  the 
  same 
  nature 
  as 
  that 
  

   which 
  led 
  him 
  to 
  say 
  the 
  hindwings 
  were 
  divided 
  into 
  5 
  plumules 
  (Zincken). 
  

   Zincken 
  is 
  wrong 
  — 
  (1) 
  Linne 
  does 
  not 
  say 
  this 
  except 
  by 
  etymological 
  implication. 
  

   (2) 
  Linne's 
  tesseradactyla 
  appears 
  to 
  be 
  quite 
  distinct 
  from 
  megadactyla 
  ( 
  = 
  gonodac- 
  

   tyla). 
  It 
  is 
  interesting 
  however, 
  as 
  being 
  the 
  first 
  occasion 
  on 
  which 
  tesseradactyla, 
  

   Linn., 
  is 
  referred 
  by 
  any 
  author 
  to 
  a 
  known 
  species. 
  

  

  \ 
  The 
  larva 
  of 
  A. 
  galactodactyla 
  feeds 
  on 
  Arctium 
  lappa 
  (Zincken). 
  

  

  § 
  Hiibner's 
  trichodactyla 
  = 
  Linne's 
  didactyla, 
  therefore 
  trichodactyla, 
  chryso- 
  

   dactyla 
  and 
  didactyla 
  of 
  Schiffermuller 
  = 
  didactyla, 
  Linne, 
  and 
  must 
  fall 
  as 
  

   synonyms 
  thereof, 
  so 
  also 
  must 
  Illiger's 
  reference 
  (Syst. 
  Verz., 
  2nd 
  ed.) 
  of 
  didactyla, 
  

   Linn., 
  under 
  rhododactyla, 
  which 
  is 
  a 
  distinct 
  species 
  (Zincken). 
  The 
  close 
  

   alliance 
  of 
  the 
  Oxyptilids 
  in 
  the 
  imaginal 
  stage 
  suggests 
  caution 
  in 
  accepting 
  this 
  

   statement 
  in 
  its 
  entirety.
