  with 
  distinct 
  anal 
  angle 
  ; 
  the 
  1st 
  plumule 
  of 
  the 
  hindwing 
  with 
  margin 
  running 
  

   obliquely, 
  from 
  within 
  and 
  above, 
  to 
  below 
  and 
  without, 
  i.e., 
  wider 
  at 
  apex 
  than 
  at 
  

   base, 
  the 
  2nd 
  pointed, 
  with 
  rounded 
  anal 
  angle, 
  the 
  3rd 
  with 
  a 
  tooth 
  of 
  black 
  

   scales 
  on 
  the 
  inner-marginal 
  fringes 
  near 
  the 
  apex 
  ;

  —

  and

   of 
  fore 
  wing 
  arise, 
  one 
  shortly 
  after 
  the 
  other, 
  before 
  the 
  upper 
  angle 
  of 
  the 
  median 
  

   cell, 
  II

  and 
  11^ 
  on 
  a 
  stalk 
  from 
  this 
  angle 
  itself, 
  II 
  5 
  from 
  the 
  discocellular, 
  which 
  

   is 
  straight 
  as 
  far 
  as 
  to 
  the 
  origin 
  of 
  this 
  vein, 
  and 
  from 
  thence 
  runs 
  somewhat 
  

   obliquely 
  downwards 
  and 
  inwards. 
  

  

  The 
  main 
  characters, 
  however, 
  in 
  which 
  Eucnemidophor 
  us 
  differs 
  from 
  

   the 
  Platyptilias 
  (sens, 
  rest.), 
  are 
  exhibited 
  in 
  the 
  early 
  stages. 
  There 
  is 
  

   in 
  the 
  larva 
  an 
  abundance 
  of 
  secondary 
  hairs, 
  and 
  there 
  is 
  also 
  a 
  tendency 
  

   for 
  the 
  primary 
  hairs 
  to 
  be 
  associated 
  with 
  a 
  few 
  secondaries, 
  indicating 
  

   the 
  first 
  step 
  in 
  wart 
  structure 
  ; 
  indications 
  of 
  the 
  accessory 
  postspirac- 
  

   ulars 
  are 
  not 
  wanting 
  [as 
  in 
  the 
  Platyptilias 
  (sens, 
  rest.)] 
  , 
  both 
  

   positions 
  being 
  occupied 
  by 
  greatly-developed 
  secondary 
  hairs. 
  The 
  

   pupa 
  resembles 
  that 
  of 
  the 
  Platyptiliids, 
  in 
  that 
  there 
  are 
  no 
  processes 
  

   or 
  marked 
  armature 
  ; 
  the 
  dorsal 
  ridge, 
  however, 
  is 
  barely 
  indicated, 
  

   and 
  the 
  primary 
  setas 
  are 
  nearly 
  as 
  well-developed 
  as 
  in 
  the 
  larva 
  ; 
  the 
  

   nose-horn, 
  however, 
  is 
  evanescent. 
  The 
  chief 
  characters 
  of 
  the 
  early 
  

   stages 
  may 
  be 
  summarised 
  as 
  follows 
  : 
  — 
  

  

  Larva. 
  — 
  Minute 
  chitinous 
  pointed 
  spiculas 
  ; 
  secondary 
  hairs 
  abundant, 
  definitely 
  

   hair-like, 
  with 
  jointed 
  base, 
  variable 
  in 
  size, 
  very 
  short 
  and 
  thick, 
  with 
  knobbed 
  

   tops, 
  appear 
  first 
  in 
  (?) 
  penultimate 
  skin 
  ; 
  primary 
  hairs 
  smooth 
  and 
  tapering 
  ; 
  

   tubercles 
  i 
  and 
  ii 
  on 
  same 
  base 
  in 
  meso- 
  and 
  metathorax 
  ; 
  trapezoidal 
  on 
  abdomen 
  ; 
  

   iv 
  and 
  v 
  with 
  conjoined 
  bases 
  ; 
  accessory 
  postspiraculars 
  indicated 
  by 
  well-developed 
  

   secondary 
  hairs 
  ; 
  vi, 
  two-haired 
  ; 
  one 
  or 
  two 
  secondary 
  hairs 
  associated 
  with 
  

   primary 
  setae. 
  

  

  Pupa. 
  — 
  Front 
  rounded, 
  nose-spine 
  evanescent 
  ; 
  surface 
  smooth, 
  without 
  

   processes 
  ; 
  dorsal 
  ridges 
  simply 
  indicated 
  (not 
  strong 
  as 
  in 
  Platyptilias) 
  ; 
  seta? 
  long, 
  

   almost 
  as 
  in 
  larva.
