  Haw.),

  (pterodactyla

  : 
  Alucita 
  adactyla, 
  A. 
  petradactyla 
  ( 
  = 
  zetterstecltii), 
  

   A. 
  cosmodactyla 
  (acanthodactyla, 
  Tr.). 
  It 
  is 
  to 
  be 
  noted 
  that 
  Hiibner's 
  

   calodactyla 
  is 
  placed 
  with 
  megadactyla 
  (gonodactyla), 
  petradactyla, 
  

   ochrodactyla 
  and 
  rhododactyla, 
  in 
  the 
  Terzeichniss, 
  all, 
  according 
  to 
  

   the 
  figures, 
  without 
  the 
  inner-marginal 
  tooth, 
  and 
  true 
  Platyptiliid 
  

   species. 
  

  

  In 
  1805, 
  Laspeyres 
  (111. 
  Mag., 
  iv., 
  pp. 
  20 
  et 
  seq.), 
  reviewing 
  

   Illiger's 
  edition 
  of 
  the 
  Vienna 
  Catalogue, 
  offers 
  many 
  criticisms, 
  and 
  

   refers 
  to 
  Hiibner's 
  plates 
  i 
  and 
  ii. 
  He 
  observes 
  that 
  (1) 
  The 
  Fabrician 
  

   P. 
  ochrodactyluH 
  cannot 
  be 
  that 
  of 
  Schiffermiiller 
  as 
  the 
  diagnoses 
  dis- 
  

   agree. 
  (2) 
  The 
  didactyla 
  of 
  Linne 
  and 
  Schifferrniiller 
  are 
  most 
  probably 
  

   different. 
  (3) 
  The 
  Hiibnerian 
  megadactyla 
  (fig. 
  6) 
  is 
  apparently 
  only 
  a 
  

   sexual 
  variety 
  of 
  his 
  calodactyla 
  (fig. 
  7).* 
  He 
  further 
  notes 
  that 
  the 
  

   Hiibnerian 
  megadactyla 
  is 
  very 
  different 
  from 
  the 
  Fabrician 
  migadac- 
  

   tylus, 
  the 
  description 
  of 
  which 
  would 
  very 
  well 
  fit 
  Hiibner's 
  galacto- 
  

   dactyla 
  f 
  (fig. 
  2), 
  but 
  Laspeyres 
  evidently 
  overlooks 
  the 
  words 
  "pedes 
  

   albi, 
  fusco 
  maculati 
  " 
  in 
  the 
  Fabrician 
  description, 
  which 
  do 
  not 
  fit 
  

   galactodactyla, 
  nor, 
  as 
  a 
  matter 
  of 
  fact, 
  any 
  of 
  the 
  truly 
  " 
  white 
  " 
  

   European 
  species, 
  and 
  renders 
  Werneburg's 
  reference 
  to 
  nemo- 
  

   ralis 
  just 
  possible, 
  though 
  nemoralis 
  is 
  not 
  a 
  " 
  white 
  " 
  species 
  in 
  any 
  

   sense. 
  

  

  In 
  1811, 
  Haworth 
  described 
  (hep. 
  Brit., 
  pp. 
  475 
  et 
  seq.) 
  the 
  group 
  

   under 
  the 
  name 
  Alucita, 
  as 
  : 
  

  

  Antennae 
  setaceae. 
  Palpi 
  duo 
  lineares. 
  Lingua 
  exserta 
  mernbranacea. 
  Corpus 
  

   pedesque 
  gracilissime 
  elongati, 
  alis 
  sedentis, 
  expansis 
  ; 
  anticis 
  bifidis, 
  rarissinie 
  

   5-6 
  partitis 
  : 
  posticis 
  3-6 
  partitis, 
  laciniis 
  plumaeformibus 
  : 
  volatu 
  tardiore, 
  vespe- 
  

   reque 
  — 
  Alucita 
  pentadactyla, 
  galactodactyla, 
  pterodactyla, 
  fuscodactyla, 
  bipuncti- 
  

   dactyla, 
  monodactyla, 
  tetradactyla 
  , 
  tridactyla, 
  leucadactyla, 
  lunaedactyla, 
  palli- 
  

   dactyla, 
  migadactyla, 
  trigonodactyla, 
  rhododactyla, 
  calodactyla, 
  punctidactyla, 
  

   tesseradactyla, 
  didactyla, 
  heterodactyla, 
  parvidactyla, 
  hexadactyla. 
  

  

  We 
  have 
  already 
  noted 
  that 
  Haworth 
  refers 
  to 
  plates 
  i 
  and 
  ii 
  of 
  

   Hiibner's 
  Sammlung 
  Europiiischer 
  Sc/niwtt., 
  and 
  that 
  his 
  other 
  references 
  

   suggest 
  that 
  he 
  knew 
  Hiibner's 
  plates 
  well 
  ; 
  there 
  is 
  little 
  doubt 
  that 
  

   Hiibner's 
  plates 
  iii-vi 
  were 
  published 
  after 
  1811 
  and 
  before 
  1818, 
  

   possibly 
  in 
  1816-1817, 
  a 
  most 
  important 
  matter 
  with 
  regard 
  to 
  the 
  

   synonymy 
  of 
  some 
  of 
  Haworth's 
  species. 
  

  

  In 
  1815, 
  Oken 
  divides 
  (Lehrb. 
  ZooL, 
  i., 
  p. 
  679) 
  the 
  plumes 
  into 
  

   two 
  genera 
  : 
  

  

  1. 
  Alucita 
  {Pterophorus)—pentadactula 
  (described), 
  monodactyla, 
  didactyla, 
  

   trichodactyla, 
  pterodactyla, 
  megadactyla. 
  

  

  2. 
  Orneodes 
  — 
  hexadactyla 
  . 
  

  

  * 
  All 
  the 
  early 
  authors 
  seem 
  to 
  have 
  recognised 
  that 
  calodactyla, 
  Ho. 
  = 
  calo- 
  

   dactyla, 
  W.V., 
  is 
  a 
  Platyptiliid, 
  and 
  closely 
  allied 
  to 
  gonodactyla, 
  YV.Y. 
  =mega- 
  

   dactyla, 
  Hb. 
  

  

  f 
  Long 
  before 
  seeing 
  this 
  criticism 
  of 
  Laspeyres, 
  we 
  had 
  already 
  referred 
  it 
  to 
  

   spilodactyla, 
  Curt., 
  a 
  species 
  the 
  latter 
  did 
  not 
  know. 
  Fabrioius' 
  additional 
  remark 
  

   about 
  the 
  legs, 
  possibly 
  obtained 
  from 
  another 
  insect 
  (none 
  of 
  the 
  white 
  species 
  

   having 
  fuscous-spotted 
  legs), 
  is 
  equally 
  inapplicable 
  to 
  spilodactyla, 
  Curt., 
  and 
  

   galactodactyla, 
  W.V., 
  Hb. 
  ; 
  besides 
  Sohiffermuller 
  was 
  not 
  likely 
  to 
  describe 
  

   galactodactyla 
  twice, 
  first 
  as 
  megadactyla 
  and 
  then 
  as 
  galactodactyla.
