  who, 
  in 
  1806, 
  maintained 
  pentadactyla 
  as 
  the 
  the 
  type 
  of 
  Pterophora 
  

   (which 
  we 
  have 
  shown 
  falls 
  as 
  a 
  synonym 
  of 
  Alucita) 
  and 
  cited 
  hexa- 
  

   dactyla 
  as 
  the 
  type 
  of 
  Ripidophora 
  (which 
  thus 
  becomes 
  synonymous 
  

   with 
  Orneodes). 
  Oken, 
  in 
  1815, 
  correctly 
  divided 
  the 
  plumes 
  into 
  

   Alucita 
  (type 
  pentadactyla, 
  described) 
  and 
  Orneodes 
  (type 
  hexadactyla) 
  

   whilst 
  in 
  the 
  same 
  year, 
  Leach 
  cited 
  their 
  synonyms 
  — 
  Pterophorus 
  

   and 
  Alucita 
  — 
  with 
  the 
  same 
  types. 
  Before 
  the 
  publication 
  of 
  Hiibner's 
  

   Verzeichniss, 
  therefore, 
  only 
  two 
  generic 
  points 
  were 
  determined, 
  viz., 
  

   Alucita 
  type 
  pentadactyla 
  and 
  Orneodes 
  type 
  hexadactyla. 
  Hiibner, 
  in 
  

   this 
  work, 
  fixed 
  adactyla 
  as 
  the 
  type 
  of 
  Audistis, 
  and 
  created 
  the 
  

   heterotypical 
  genera 
  Platyptilia, 
  Amblyptilia, 
  Stenoptilia 
  and 
  Aciptilia. 
  

   As 
  Aciptilia 
  contained 
  pentadactyla, 
  the 
  type 
  of 
  Alucita, 
  it 
  falls 
  as 
  a 
  

   synonym 
  of 
  the 
  latter, 
  whilst 
  Euchiridia 
  (type 
  hexadactyla), 
  also 
  

   newly 
  described 
  here, 
  falls 
  as 
  a 
  synonym 
  of 
  Orneodes. 
  In 
  1833, 
  

   Curtis 
  created 
  Adactylus, 
  describing 
  the 
  genus 
  from, 
  and 
  founding 
  

   it 
  on, 
  bennetii, 
  although 
  he 
  cites 
  huebneri 
  (adactyla, 
  Hb.) 
  as 
  the 
  

   type. 
  Neither 
  Stephens 
  in 
  1834, 
  nor 
  Zeller 
  in 
  1841, 
  did 
  anything 
  

   in 
  the 
  way 
  of 
  fixing 
  generic 
  types, 
  although 
  the 
  latter 
  restricted 
  

   Amblyptilia 
  to 
  acanthodactyla, 
  Hb., 
  and 
  cosmodactyla 
  Hb., 
  and 
  

   created 
  Oxyptilus 
  for 
  the 
  other 
  section 
  of 
  Hiibner's 
  Amblyp- 
  

   tilia. 
  He 
  also 
  altered 
  the 
  spelling 
  of 
  Platyptilia 
  to 
  Platyptilus, 
  and 
  

   Aciptilia 
  to 
  Adptilus, 
  the 
  latter 
  automatically 
  falling 
  before 
  Alucita. 
  

   In 
  1852, 
  he 
  retained 
  these 
  Zellerian 
  names, 
  as 
  also, 
  in 
  1855, 
  did 
  

   Herrich-Sch 
  after, 
  but 
  with 
  subfamily 
  values, 
  the 
  groups 
  being 
  divided 
  

   and 
  subdivided 
  into 
  sections 
  of 
  modern 
  tribal 
  and 
  generic 
  values. 
  

   Zeller 
  also 
  created 
  Diacrotricha 
  (type 
  fasciola) 
  and 
  Deuterocopus 
  (type 
  

   tengstroemi). 
  In 
  1862, 
  Wallengren 
  created 
  Cnaemidophorus 
  (type 
  rho- 
  

   dodactyla), 
  Oidaematophorus 
  (type 
  lithodactyla), 
  Mimaeseoptilus 
  (for 
  the 
  

   pterodactyla 
  group 
  of 
  Hiibner's 
  Stenoptilia), 
  and 
  Leioptilus 
  for 
  the 
  

   tephr 
  adactyla 
  group 
  of 
  tbe 
  same 
  genus. 
  As, 
  however, 
  Meyrick, 
  in 
  1890, 
  

   limited 
  Stenoptilia 
  to 
  the 
  first 
  of 
  these 
  two 
  groups, 
  Mimaeseoptilus 
  fell 
  as 
  

   a 
  synonym 
  of 
  Stenoptilia. 
  Wallengren 
  also 
  fixed 
  acanthodactyla 
  as 
  the 
  

   type 
  of 
  Amblyptilus 
  (ilia), 
  Hb. 
  He 
  further 
  maintained 
  Platyptilus 
  

   (ilia), 
  Hb., 
  for 
  the 
  group 
  of 
  species 
  without 
  a 
  tooth 
  on 
  the 
  inner 
  

   margin 
  of 
  the 
  forewing, 
  followed 
  Zeller 
  in 
  using 
  Oxyptilus 
  for 
  the 
  

   pilosellae 
  group, 
  which, 
  however, 
  he 
  was 
  advanced 
  enough 
  to 
  divide 
  

   into 
  three 
  sections. 
  In 
  1864, 
  Walker 
  erected 
  two 
  genera, 
  Sochchora 
  

   (type 
  donatella), 
  JJtuca 
  (type 
  ochracealis), 
  and 
  in 
  1865, 
  a 
  third, 
  

   Paelia 
  (type 
  lunuligera), 
  whilst, 
  in 
  1880, 
  Walsingham 
  created 
  

   Trichoptilus 
  (type 
  pygmaeus), 
  and 
  Wallengren 
  altered 
  the 
  pre- 
  

   occupied 
  Cnaemidophorus 
  to 
  Eucnaemidophomis 
  and 
  created 
  Pselno- 
  

   phorus 
  (type 
  brachydactyla). 
  The 
  later 
  genera 
  will 
  be 
  readily 
  followed 
  

   in 
  the 
  generic 
  summary 
  attached 
  hereto. 
  We 
  will 
  only 
  add 
  that, 
  in 
  

   1890, 
  Meyrick 
  made 
  one 
  of 
  the 
  most 
  retrograde 
  steps 
  in 
  the 
  classifica- 
  

   tion 
  of 
  the 
  group. 
  He 
  appears 
  to 
  have 
  been 
  absolutely 
  ignorant 
  of 
  

   the 
  details 
  of 
  their 
  early 
  stages, 
  and, 
  on 
  certain 
  imaginal 
  characters, 
  

   lumped 
  together 
  the 
  most 
  diverse 
  species. 
  He 
  maintained 
  the 
  Ameri- 
  

   can 
  genus 
  Trichoptilus, 
  Walsni., 
  for 
  pallidum 
  and 
  siceliota 
  ; 
  placed 
  all 
  

   the 
  species 
  of 
  the 
  Plaptyptiliinae 
  and 
  Amblyptiliinae 
  in 
  the 
  genus 
  

   Platyptilia, 
  Hb., 
  joined 
  under 
  the 
  generic 
  name 
  Alucita, 
  Linn., 
  the 
  

   whole 
  of 
  the 
  Oidaematophorinae 
  and 
  Leioptilinae, 
  created 
  Marasmarcha 
  

   for 
  species 
  as 
  divergent 
  as 
  lunaedactyla 
  (phaeodactyla) 
  and 
  microdactyla 
  

   (leaving 
  scarodactyla 
  with 
  lieniyianus 
  in 
  Alucita), 
  created 
  Gypsochares
