  Platyptilns, 
  and 
  created 
  Oxyptilus 
  for 
  the 
  group 
  we 
  are 
  now 
  considering. 
  

   This 
  grouping 
  he 
  maintained 
  in 
  1852 
  [Linn. 
  Ent., 
  vi., 
  p. 
  342), 
  and 
  in 
  

   this 
  was 
  followed 
  by 
  Herrich-Schaffer, 
  who, 
  after 
  giving 
  a 
  detailed 
  

   description 
  of 
  the 
  group 
  (Sys. 
  Bearb., 
  v., 
  p. 
  373), 
  diagnosed 
  the

  him

  Wallengren, 
  like 
  Herrich-Schaffer, 
  recognised 
  that 
  the 
  Oxyptilids 
  

   did 
  not 
  form 
  a 
  single 
  homogeneous 
  generic 
  group, 
  and 
  described 
  the 
  

   whole 
  subfamily 
  under 
  the 
  name 
  Oxyptilus, 
  diagnosing 
  the 
  group 
  

   (Skand. 
  Fjaderm., 
  p. 
  14) 
  as 
  follows 
  : 
  — 
  

  

  Antennae 
  of 
  both 
  sexes 
  with 
  very 
  short 
  cilia. 
  The 
  forehead 
  obtuse, 
  wanting 
  

   the 
  tuft 
  or 
  cone 
  entirely. 
  The 
  palpi 
  longer 
  than 
  the 
  head, 
  thick, 
  laterally 
  

   compressed, 
  ascending, 
  the 
  middle 
  joint 
  tufted 
  at 
  its 
  apex, 
  the 
  last 
  joint 
  longer 
  

   than 
  the 
  tuft, 
  slender, 
  pointed. 
  Leg? 
  long 
  and 
  slender, 
  the 
  posterior 
  tibiae 
  

   thickened 
  with 
  scales 
  at 
  the 
  middle, 
  and 
  at 
  the 
  apex. 
  The 
  first 
  pair 
  of 
  spines 
  in 
  

   the 
  posterior 
  tibiae 
  almost 
  equal, 
  the 
  second 
  pair 
  shorter 
  than 
  the 
  shortest 
  spine 
  of 
  

   the 
  first 
  pair. 
  The 
  anterior 
  wings 
  cleft 
  more 
  than 
  the 
  third 
  part 
  of 
  their 
  length. 
  

   The 
  segments 
  slender, 
  the 
  anterior 
  segment 
  with 
  no 
  posterior 
  angle, 
  the 
  posterior 
  

   segment 
  with 
  the 
  angle 
  distinct. 
  The 
  segments 
  of 
  the 
  posterior 
  wings 
  slender, 
  the 
  

   third 
  segment 
  linear, 
  and 
  with 
  no 
  anal 
  angle. 
  The 
  anterior 
  wings 
  flat, 
  when 
  at 
  

   rest 
  covering 
  the 
  posterior 
  ; 
  the 
  inner 
  margin 
  of 
  the 
  anterior 
  wings 
  not 
  toothed 
  ; 
  the 
  

   fringe 
  of 
  the 
  third 
  segment 
  in 
  the 
  posterior 
  wings 
  with 
  some 
  black 
  scales 
  near 
  the 
  

   apex. 
  Veins 
  of 
  the 
  anterior 
  wings 
  eight 
  in 
  number, 
  the 
  first 
  and 
  second 
  separate, 
  

   springing 
  from 
  the 
  base, 
  the 
  third 
  from 
  he 
  posterior 
  margin 
  of 
  the 
  cell, 
  the 
  fourth 
  

   dividing 
  into 
  two 
  branches, 
  running 
  from 
  the 
  posterior 
  angle 
  of 
  the 
  cell 
  to 
  the 
  

   posterior 
  segment, 
  the 
  fifth 
  coming 
  out 
  near 
  the 
  anterior 
  angle 
  of 
  the 
  cell 
  and 
  

   running 
  to 
  the 
  posterior 
  margin 
  of 
  the 
  anterior 
  segment, 
  the 
  sixth, 
  either 
  two- 
  or 
  

   three-branched, 
  running 
  from 
  the 
  anterior 
  angle 
  of 
  the 
  cell 
  to 
  the 
  apex 
  of 
  the 
  

   anterior 
  segment, 
  the 
  seventh 
  from 
  the 
  anterior 
  side 
  of 
  the 
  cell, 
  and 
  the 
  eighth 
  from 
  

   the 
  base. 
  The 
  cell 
  distinct, 
  closed, 
  the 
  transverse 
  vein 
  very 
  slender, 
  somewhat 
  

   arched. 
  The 
  veins 
  of 
  the 
  posterior 
  wings 
  three, 
  the 
  first, 
  two-branched, 
  running 
  

   to 
  the 
  first 
  segment, 
  the 
  second, 
  also 
  two-branched, 
  running 
  into 
  the 
  second 
  

   segment, 
  the 
  third 
  simply 
  running 
  into 
  the 
  third 
  segment. 
  No 
  coll. 
  

  

  Wallengren 
  followed 
  Zeller, 
  and 
  the 
  earlier 
  authors, 
  in 
  using 
  his 
  

   genera 
  in 
  the 
  modern 
  sense 
  of 
  tribes, 
  but 
  he 
  clearly 
  understood 
  that 
  

   the 
  species 
  grouped 
  themselves 
  into 
  smaller 
  (modern 
  generic) 
  sections 
  

   of 
  his 
  main 
  division. 
  He, 
  however, 
  did 
  not 
  name 
  the 
  sections, 
  which 
  

   he 
  described 
  as 
  follows 
  : 
  — 
  

  

  I. 
  Forewings 
  with 
  white 
  markings 
  en 
  the 
  upperside. 
  Hindwings 
  with 
  the 
  

   underside 
  of 
  the 
  first 
  plumule 
  furnished 
  with 
  a 
  white 
  spot 
  at 
  the 
  apex.
