  BRITISH 
  LEPIDOPTERA. 
  

  

  Stenoptiliines 
  and 
  the 
  Platyptiliines. 
  Chapman 
  observes 
  that 
  the 
  

   larval 
  hairs 
  of 
  Eucnemidophorus 
  are 
  much 
  as 
  in 
  Marasmarcha, 
  the 
  skin- 
  

   hairs 
  distinctly 
  of 
  Amblyptiliid 
  type, 
  whilst 
  many 
  of 
  the 
  primary 
  

   setae 
  are 
  knobbed 
  ; 
  he 
  further 
  notes 
  that 
  the 
  postspiracular 
  hairs, 
  

   representing 
  the 
  accessory 
  tubercles, 
  are 
  well-represented 
  on 
  some 
  

   segments, 
  absent 
  on 
  others, 
  and 
  again 
  not 
  so 
  very 
  different 
  from 
  those 
  of 
  

   Marasmarcha. 
  It 
  is 
  a 
  most 
  important 
  fact 
  that 
  these 
  well-developed 
  

   secondary 
  skin-hairs 
  are 
  distinctly 
  Amblyptiliid 
  (not 
  Platyptiliid), 
  i.e., 
  

   they 
  are 
  jointed 
  secondary 
  hairs, 
  as 
  in 
  the 
  more 
  external-feeding 
  larvae 
  

   of 
  the 
  Platyptiliid 
  stirps, 
  and 
  not 
  minute 
  unjointed 
  skin-points, 
  as 
  in 
  

   the 
  internal-feeding 
  Platyptiliid 
  larvae. 
  

  

  In 
  the 
  Eucnemidophorid 
  pupa, 
  the 
  dorsal 
  ridge 
  is 
  rather 
  poorly 
  

   indicated; 
  there 
  is 
  a 
  suspicion 
  of 
  a 
  pupal 
  nose-horn; 
  the 
  skin 
  is 
  smooth, 
  

   and 
  innocent 
  of 
  processes, 
  except 
  the 
  ordinary 
  primary 
  setae, 
  which 
  are 
  as 
  

   long 
  as 
  those 
  of 
  the 
  larva, 
  but 
  sometimes 
  knobbed 
  towards 
  the 
  tip. 
  Bacot 
  

   observes 
  that 
  the 
  pupa 
  is 
  of 
  Platyptiliid 
  outline, 
  nearer 
  to 
  that 
  of 
  Maras- 
  

   marcha 
  than 
  Amblyptilia, 
  and 
  far 
  removed 
  from 
  those 
  of 
  Stenoptilia 
  and 
  

   Adkinia 
  ; 
  the 
  hairs, 
  he 
  says, 
  are 
  very 
  long, 
  and, 
  in 
  this 
  character, 
  it 
  agrees 
  

   neither 
  with 
  the 
  Platyptiliines, 
  nor 
  the 
  Amblyptiliines. 
  Chapman 
  

   observes 
  that 
  these 
  hairs 
  are 
  exceedingly 
  long, 
  compared 
  with 
  those 
  

   in 
  Platyptiliine 
  pupae, 
  whilst 
  he 
  suggests 
  that 
  the 
  pupa 
  of 
  Marasmarcha 
  

   shows 
  distinct 
  Oxyptilid 
  indications 
  ; 
  strangely 
  enough, 
  the 
  pupa 
  of 
  

   Eucnemidophorus 
  has 
  much 
  more 
  in 
  common 
  with 
  that 
  of 
  Buckleria 
  

   (pallidum) 
  than 
  with 
  that 
  of 
  any 
  of 
  the 
  Platyptilias. 
  

  

  The 
  special 
  characters 
  above 
  noted, 
  are, 
  perhaps, 
  partly 
  due 
  to 
  the 
  

   fact 
  that 
  the 
  larva 
  of 
  Eucnemidophorus 
  is 
  not 
  so 
  truly 
  an 
  external 
  

   feeder 
  as 
  the 
  members 
  of 
  the 
  allied 
  subfamilies 
  just 
  considered, 
  and 
  that 
  

   something 
  of 
  a 
  cocoon 
  is 
  always 
  spun 
  for 
  pupation, 
  there 
  being, 
  therefore, 
  

   less 
  need 
  for 
  complicated 
  development 
  in 
  these 
  directions. 
  Bacot 
  notes 
  

   that, 
  in 
  its 
  cocoon-forming 
  habit, 
  Eucnemidophorus 
  inclines 
  to 
  the 
  

   Platyptiliines, 
  as 
  also 
  in 
  the 
  manner 
  in 
  which 
  it 
  lies 
  therein, 
  rather 
  

   than 
  is 
  attached, 
  in 
  the 
  manner 
  of 
  the 
  Amblyptiliines, 
  by 
  means 
  of 
  a 
  

   complicated 
  cremaster 
  on 
  the 
  8th 
  and 
  10th 
  abdominal 
  segments. 
  

  

  It 
  is 
  quite 
  open 
  to 
  question, 
  as 
  already 
  noted, 
  whether 
  this 
  tribe 
  

   should 
  really 
  be 
  considered 
  as 
  of 
  full 
  subfamily 
  rank 
  ; 
  it 
  is, 
  in 
  its 
  

   larval 
  and 
  pupal 
  characters, 
  as 
  we 
  have 
  shown, 
  much 
  more 
  inclined 
  

   to 
  the 
  Platyptiliines 
  than 
  to 
  the 
  Stenoptiliines 
  in 
  the 
  imaginal, 
  

   larval, 
  and 
  pupal 
  stages, 
  and 
  retains 
  the, 
  for 
  this 
  superfamily, 
  peculiar 
  

   cocoon 
  -spinning 
  habit 
  in 
  an 
  enhanced 
  form, 
  seen 
  nowhere 
  among 
  

   the 
  Alucitids 
  (sens, 
  lat.), 
  except 
  in 
  the 
  Platyptiliids 
  (that 
  of 
  Adaina 
  

   not 
  being 
  a 
  true 
  spun 
  cocoon).
