  Bed 
  -brown 
  or 
  yellow-brown,

  the 
  lower 
  

  

  lobe

  B. 
  The 
  scale-tuft 
  of 
  the 
  inner 
  margin 
  of 
  the 
  3rd 
  feather 
  close 
  to 
  the 
  

  

  apex, 
  or 
  surrounding 
  it. 
  

  

  1. 
  The 
  black 
  scales 
  of 
  the 
  3rd 
  feather 
  shorter 
  on 
  the 
  costa 
  than 
  

  

  on 
  the 
  inner 
  margin. 
  

  

  a. 
  The 
  black 
  scales 
  of 
  3rd 
  feather 
  run, 
  neither 
  on 
  the 
  

  

  costa 
  nor 
  on 
  the 
  inner 
  margin, 
  quite 
  to 
  the 
  apex, 
  

   which 
  is 
  white-scaled 
  on 
  both 
  sides, 
  and 
  only 
  

   bears, 
  exceptionally,

  b. 
  The 
  black 
  scales

  3rd 
  feather 
  run, 
  on 
  the 
  costa, 
  

  

  almost 
  or 
  quite 
  up 
  to 
  the 
  apex, 
  which 
  bears, 
  besides, 
  

   also 
  a 
  small 
  downwards-directed 
  scale-tuft. 
  On 
  the 
  

   inner 
  margin, 
  the 
  black 
  scales 
  do 
  not 
  quite 
  reach 
  

   up 
  to 
  the 
  apex, 
  a.re 
  longest 
  towards 
  the 
  base, 
  and 
  

   become 
  shorter 
  towards 
  the 
  apex, 
  so 
  that 
  the 
  

   scaling, 
  as 
  a

  2. 
  The 
  black 
  scales 
  of 
  the 
  3rd 
  feather 
  are, 
  on 
  the 
  inner 
  margin 
  

  

  and 
  costa, 
  of 
  equal 
  length, 
  and 
  run, 
  on 
  both 
  sides, 
  to 
  the 
  very 
  

   tip, 
  which 
  is 
  sometimes, 
  at 
  this 
  point, 
  also 
  furnished 
  with 
  

   some 
  white 
  scales. 
  

  

  a. 
  The 
  fringes 
  of 
  the 
  outer 
  margin 
  of 
  the 
  lower 
  lobe 
  with 
  

  

  a 
  white 
  or 
  pale 
  basal 
  line 
  . 
  . 
  ericetoram,

  b. 
  The 
  fringes 
  of 
  the 
  outer 
  margin 
  of 
  the 
  lower 
  lobe 
  with 
  

  

  a 
  white 
  dash 
  at 
  the 
  anal 
  angle 
  parvidactylus, 
  Hw. 
  

  

  The 
  pupal 
  characters 
  of 
  this 
  tribe 
  exhibit 
  an 
  intermediate 
  stage 
  

   between 
  the 
  more 
  normal 
  Platyptiliid 
  pupae, 
  and 
  the 
  more 
  extreme 
  

   form 
  represented 
  by 
  Capperia. 
  The 
  pupa 
  is, 
  in 
  the 
  Oxyptilids 
  (sens. 
  

   rest.), 
  free 
  from 
  warts, 
  but 
  has 
  long, 
  well- 
  developed, 
  primary 
  hairs, 
  

   without 
  any 
  trace 
  of 
  secondaries 
  in 
  connection 
  with 
  the 
  tubercles, 
  or 
  

   on 
  the 
  skin 
  -surf 
  ace; 
  the 
  dorsal 
  flanges 
  are 
  well-developed; 
  but, 
  although 
  

   the 
  pupa 
  has 
  a 
  single 
  median, 
  unpaired, 
  spine 
  on 
  the 
  abdominal 
  segments 
  

   1-8, 
  it 
  does 
  not 
  show 
  the 
  highly-specialised 
  structure, 
  of 
  Capperia 
  

   (heterodactyla) 
  , 
  in 
  which 
  the 
  pupa 
  has, 
  on 
  the 
  abdominal 
  segments, 
  a 
  

   double 
  spine 
  on 
  either 
  side, 
  internal 
  to 
  i 
  and 
  ii. 
  [Single 
  spines 
  or 
  

   hairs 
  occur 
  in 
  certain 
  pupae 
  on 
  the 
  Alucitid 
  side 
  of 
  the 
  stirps, 
  e.g., 
  

   Alucita 
  (pentadactyla), 
  and 
  Oidaematophorus 
  (lithodactyla).] 
  

  

  It 
  is, 
  however, 
  in 
  the 
  larval 
  characters, 
  that 
  the 
  Oxyptilidi 
  differ 
  

   most 
  from 
  the 
  Capperiidi. 
  The 
  former 
  are 
  practically 
  Platyptiliid 
  in 
  

   structure 
  and 
  habit 
  ; 
  the 
  larvae 
  being 
  largely 
  (if 
  not 
  entirely) 
  internal 
  

   feeders, 
  whilst 
  the 
  latter 
  are 
  external 
  feeders, 
  this 
  difference 
  in 
  habit 
  

   being 
  associated 
  with 
  a 
  marked 
  difference 
  in 
  structure, 
  for, 
  whilst 
  the 
  

   Oxyptilidi 
  are 
  essentially 
  simple 
  in 
  their 
  structure, 
  with 
  no 
  indications 
  

   of 
  wart- 
  structure, 
  or 
  at 
  least 
  none 
  exceeding, 
  or 
  even 
  reaching, 
  that 
  of
