  In 
  1827, 
  Curtis 
  gave 
  {Brit. 
  Ent., 
  fo. 
  161) 
  a 
  short 
  classification 
  of 
  

   the 
  British 
  plumes 
  (adding 
  five 
  species 
  to 
  Haworth's 
  list) 
  under 
  the 
  

   group 
  name 
  Pterophorus, 
  which 
  he 
  divides 
  into 
  Sections 
  A 
  and 
  B. 
  

   His 
  summary 
  is 
  as 
  follows 
  : 
  

  

  A. 
  Abdominal 
  ray 
  not 
  lobed 
  — 
  tetradactylus, 
  ochrodactylus, 
  pentadactijlus, 
  

   galactodactylus 
  (albodactylus) 
  , 
  spilod 
  actylus 
  , 
  tridactylus, 
  citridactylus, 
  leucodactylus, 
  

   pterodactylus, 
  monodactylus, 
  tepliradactylus, 
  bipunctidactylus, 
  fuscodactylus 
  , 
  

   migadactylus, 
  phaeodactylus, 
  lunaedactylus. 
  

  

  B. 
  Abdominal 
  ray 
  producing 
  a 
  bundle 
  of 
  scales 
  forming 
  a 
  lobe 
  on 
  the 
  internal 
  

   margin 
  — 
  didactylus 
  ( 
  — 
  heterodactylus), 
  rhododactylus, 
  trigonodactylus, 
  calodactylus, 
  

   tesseradactylus, 
  punctidactylus, 
  microdactylus 
  (=parvidactylus). 
  

  

  The 
  type 
  of 
  Pterophorus, 
  he 
  cites 
  as 
  pentadactyla, 
  Linn. 
  Later, 
  in 
  

   1833 
  (op. 
  cit., 
  fo. 
  471), 
  he 
  diagnoses 
  the 
  genus 
  Adactylm, 
  describing 
  it 
  

   in 
  full 
  from 
  the 
  characters 
  offered 
  by 
  bennetii, 
  but 
  citing 
  as 
  type 
  

   Alucita 
  adactyla, 
  Hb., 
  whilst 
  in 
  fo. 
  695 
  hexadactyla 
  is 
  cited 
  as 
  the 
  

   type 
  of 
  Alucita. 
  

  

  In 
  1833, 
  Treitschke 
  gives 
  (Die 
  Schmett., 
  etc., 
  ix., 
  pt. 
  2, 
  pp. 
  225 
  

   et 
  seq.) 
  another 
  out-of-date 
  grouping, 
  in 
  the 
  face 
  of 
  Hubner's 
  well- 
  

   known 
  work. 
  He 
  places 
  all 
  the 
  plumes 
  in 
  Alucita, 
  w 
  T 
  hich 
  he 
  divides* 
  

   into 
  four 
  families 
  as 
  follows 
  : 
  

  

  Fam. 
  A. 
  — 
  The 
  imago 
  with 
  entire 
  undivided 
  wings 
  — 
  adactyla, 
  Hb. 
  

  

  Fam. 
  B. 
  — 
  The 
  imagines 
  with 
  broad 
  forewings, 
  cut 
  out 
  sickle-like 
  on 
  the 
  hind 
  

   margin, 
  with 
  one 
  short 
  cleft, 
  the 
  lobes 
  drawn 
  close 
  together; 
  the 
  hindwings 
  con- 
  

   sisting 
  of 
  three 
  plumules 
  — 
  ochrodactyla, 
  Hb.. 
  rhododactyla 
  , 
  Fab., 
  tesseradactyla, 
  

   Linn., 
  calodactyla, 
  Hb., 
  graphodactyla, 
  Tr., 
  acanthodactyla, 
  Hb., 
  cosmo- 
  

   dactyla, 
  Hb. 
  

  

  Fam. 
  C. 
  — 
  With 
  narrow, 
  more 
  deeply 
  cleft 
  forewings, 
  club-like 
  towards 
  the 
  

   hind-margin 
  ; 
  the 
  hindwings 
  divided 
  into 
  three 
  plumules 
  — 
  didactyla, 
  Linn., 
  

   brachydactyla. 
  Koll., 
  phaeodactyla, 
  Hb., 
  mictodactyla, 
  Hb., 
  pterodactyla, 
  Hb., 
  

   ptilodactyla, 
  Hb.,

  ,

  Hb.), 
  microdactyla, 
  Tr. 
  

  

  Fam. 
  D. 
  — 
  Wings 
  deeply 
  cleft, 
  the 
  forewings 
  into 
  two, 
  the 
  hindwings 
  into 
  three, 
  

   plumules 
  — 
  pentadactyla, 
  Linn., 
  galactodactyla, 
  Hb., 
  xantkodactyla, 
  Tr., 
  tetra- 
  

   ■dactyla, 
  Linn. 
  

  

  In 
  1834, 
  Stephens 
  made 
  an 
  attempt 
  to 
  apply 
  Hubner's 
  classification 
  

   to 
  the 
  British 
  plumes, 
  and 
  grouped 
  (Illus. 
  Brit. 
  Ent. 
  Haust., 
  iv., 
  pp 
  

   370 
  et 
  seq.) 
  them 
  as 
  follows 
  : 
  

  

  1. 
  Undivided 
  wings, 
  short 
  truncate 
  palpi, 
  minute 
  spurs 
  to 
  hinder 
  tibite 
  — 
  

   Agdistis 
  (bennetii). 
  

  

  2. 
  Anterior 
  wings 
  divided 
  into 
  two 
  or 
  three 
  feathers, 
  the 
  posterior 
  into 
  three 
  — 
  

   Pterophorus. 
  

  

  A. 
  Posterior 
  wings 
  without 
  an 
  appendage 
  on 
  the 
  inner 
  margin. 
  

  

  a. 
  Anterior 
  wings 
  broad, 
  deeply 
  cleft, 
  pale 
  — 
  Aciptilia 
  pentadactylus, 
  

  

  spilodactylus, 
  galactodactylus. 
  

  

  b. 
  Anterior 
  wings 
  narrow, 
  deeply 
  cleft 
  and 
  acute, 
  generally 
  without 
  

  

  any 
  distinct 
  markings 
  — 
  Stenoptilia 
  bipunctidactylus, 
  fusco- 
  

   dactylus 
  (pterodactylus), 
  monodactylus, 
  tephradactylus, 
  tri- 
  

   dactylus, 
  niveidactylus, 
  tetradactylus, 
  carpodactylus,

  pallidactylus, 
  miga- 
  

   dactylus, 
  svmilidactylus. 
  

  

  B. 
  Posterior 
  wings 
  with 
  an 
  appendage 
  on 
  the 
  inner 
  margin. 
  

  

  a. 
  Anterior 
  wings 
  broad 
  and 
  acute 
  — 
  Platyptilia 
  trigonodactylus, 
  

   rhododactylus, 
  calodactylus. 
  

  

  * 
  Like 
  Linne, 
  Barbut 
  and 
  the 
  other 
  early 
  authors. 
  Treitschke 
  uses 
  the 
  term 
  

   "genus" 
  in 
  a 
  " 
  superfamily 
  " 
  sense, 
  dividing 
  the 
  genus 
  into 
  •• 
  families," 
  eto, 
  so 
  

   also 
  did 
  Zeller 
  (see 
  posted).
