  about 
  the 
  fifth 
  or 
  sixth 
  row, 
  whence 
  radiating 
  lines 
  or 
  ridges 
  proceed 
  to 
  

   the 
  centre. 
  The 
  antennae 
  extend 
  down 
  either 
  side 
  and 
  reach 
  to 
  very 
  

   nearly 
  the 
  ends 
  of 
  the 
  wings. 
  Their 
  markings 
  of 
  transverse 
  wrinkles 
  

   are 
  very 
  like, 
  and 
  not 
  seemingly 
  more 
  special 
  than, 
  those 
  on 
  the 
  legs. 
  

   The 
  maxillae 
  (proboscis) 
  occupy 
  the 
  middle 
  of 
  the 
  front 
  below 
  the 
  

   head; 
  for 
  the 
  first 
  millimetre 
  they 
  are 
  rather 
  wide 
  (each 
  043mm.), 
  

   then 
  narrow 
  rather 
  quickly 
  to 
  half 
  the 
  width, 
  till 
  about 
  two-thirds 
  of 
  

   the 
  way 
  to 
  the 
  end 
  of 
  the 
  wings 
  they 
  become 
  extremely 
  narrow, 
  or 
  

   even 
  invisible, 
  not 
  by 
  actual 
  lessened 
  bulk, 
  but 
  by 
  being 
  covered 
  by 
  

   the 
  first 
  legs; 
  on 
  the 
  specimen 
  being 
  carefully 
  observed, 
  there 
  is, 
  

   however, 
  a 
  portion 
  exposed 
  to 
  their 
  very 
  extremities 
  ; 
  beyond 
  the 
  first 
  

   legs 
  they 
  are 
  similarly 
  overlaid 
  by 
  the 
  second 
  legs, 
  and 
  disappear 
  a 
  little 
  

   before 
  half-way 
  between 
  the 
  ends 
  of 
  the 
  first 
  legs 
  (and 
  wings) 
  and 
  the 
  

   second. 
  The 
  first 
  legs 
  begin 
  rather 
  widely, 
  against 
  the 
  antennae, 
  and 
  

   narrow 
  very 
  slightly 
  and 
  gradually, 
  finally 
  tapering 
  rapidly 
  to 
  a 
  point 
  

   level 
  with 
  the 
  ends 
  of 
  the 
  wings. 
  The 
  second 
  legs 
  begin 
  between 
  the 
  first 
  

   leg 
  and 
  antenna, 
  close 
  to 
  the 
  upper 
  end 
  of 
  first 
  legs. 
  They 
  widen 
  out 
  

   decidedly 
  just 
  beyond 
  the 
  end 
  of 
  the 
  antennae, 
  to 
  fill 
  up 
  as 
  it 
  were 
  the 
  

   extra 
  space 
  available, 
  and 
  end 
  about 
  3-6mm. 
  beyond 
  the 
  wings 
  opposite 
  

   the 
  6th 
  or 
  7th 
  abdominal 
  segment 
  (according 
  to 
  the 
  degree 
  to 
  which 
  

   the 
  pupal 
  segments 
  are 
  extended). 
  Here 
  they 
  form 
  a 
  stiff 
  process 
  in 
  

   conjunction 
  with 
  the 
  ends 
  of 
  the 
  maxillae 
  and 
  the 
  third 
  legs, 
  which 
  

   appear 
  from 
  beneath 
  the 
  wings, 
  and 
  are 
  so 
  much 
  behind 
  the 
  second, 
  

   that 
  they 
  might 
  escape 
  notice 
  ; 
  they 
  extend 
  fractionally 
  beyond 
  the 
  

   second 
  pair. 
  This 
  stiff 
  process 
  is 
  quite 
  free, 
  and 
  applied 
  to 
  the 
  pupal 
  

   surface 
  when 
  at 
  rest, 
  but 
  when 
  the 
  pupa 
  throws 
  itself 
  back, 
  Alucitid 
  

   fashion, 
  it 
  stands 
  out 
  prominently. 
  The 
  prothorax 
  has 
  the 
  hairs 
  too 
  

   evanescent 
  to 
  be 
  accurately 
  determined. 
  The 
  mesothorax 
  is 
  large 
  and 
  

   prominent, 
  it 
  has 
  the 
  trapezoidal 
  hairs, 
  and 
  laterally 
  are 
  two 
  hairs 
  one 
  

   above 
  the 
  other 
  ; 
  there 
  is 
  a 
  curious 
  hollow 
  in 
  the 
  wing-base, 
  just 
  in 
  

   line 
  with 
  the 
  posterior 
  margin 
  of 
  the 
  mesothorax. 
  The 
  wings 
  are 
  

   marked 
  by 
  minute, 
  transverse, 
  compound 
  wrinkles, 
  along 
  which 
  the 
  

   colouring 
  is 
  more 
  intense; 
  there 
  are 
  indications 
  of 
  the 
  neuration. 
  The 
  

   wings 
  are 
  attached 
  down 
  to 
  their 
  pointed 
  extremities, 
  ending 
  at 
  the 
  

   posterior 
  margin 
  of 
  the 
  3rd 
  abdominal 
  segment. 
  Dehiscence 
  causes 
  

   splitting 
  of 
  the 
  mesothorax 
  to 
  a 
  point 
  short 
  of 
  its 
  posterior 
  border. 
  The 
  

   metathorax 
  has 
  a 
  dorsal 
  keel 
  or 
  carina 
  ; 
  in 
  the 
  specimen 
  examined 
  

   there 
  is 
  a 
  hair 
  near 
  the 
  middle 
  line 
  in 
  front, 
  and 
  another 
  near 
  the 
  outer 
  

   anterior 
  angle, 
  and, 
  on 
  each 
  side, 
  there 
  is 
  a 
  third, 
  but 
  on 
  one 
  side 
  it 
  

   lies 
  parallel 
  with, 
  and 
  a 
  little 
  outside, 
  the 
  first 
  ; 
  on 
  the 
  other 
  side 
  

   it 
  is 
  more 
  than 
  half-way 
  to 
  the 
  outer 
  one. 
  The 
  hindwing 
  is 
  a 
  broad 
  

   short 
  strip, 
  ending 
  rather 
  abruptly 
  opposite 
  the 
  spiracle 
  of 
  the 
  2nd 
  

   abdominal 
  segment. 
  The 
  1st 
  abdominal 
  segment 
  is 
  a 
  square 
  dorsal 
  

   piece 
  and 
  has 
  the 
  four 
  trapezoidals 
  disposed 
  widely 
  apart, 
  in 
  nearly 
  

   a 
  square, 
  but 
  the 
  posterior 
  a 
  little 
  further 
  out 
  as 
  if 
  to 
  occupy 
  the 
  

   whole 
  segment 
  as 
  commandingly 
  as 
  possible 
  ; 
  there 
  is 
  another 
  

   tubercle, 
  which 
  hardly 
  escapes 
  being 
  covered 
  by 
  the 
  hindwing 
  and 
  just 
  

   in 
  line 
  with 
  i 
  ; 
  the 
  hairs 
  of 
  the 
  trapezoidals 
  are 
  distinctly 
  of 
  the 
  

   Indian 
  club-shape 
  common 
  on 
  the 
  larva. 
  The 
  2nd 
  abdominal 
  segment 
  

   is 
  longer 
  than 
  broad, 
  tubercle 
  i 
  two-fifths 
  of 
  segment 
  from 
  front 
  edge, 
  

   ii 
  slightly 
  further 
  out, 
  about 
  four-fifths, 
  iii 
  just 
  above 
  spiracle 
  and 
  

   amongst 
  the 
  longitudinal 
  wrinkles 
  bordering 
  the 
  wing 
  ; 
  just 
  behind 
  

   the 
  spiracle 
  is 
  a 
  rugosity, 
  that 
  is 
  more 
  marked 
  in 
  the 
  following 
  segments.
