  They

  separate

  which 
  

   the 
  var. 
  tuttodactyla* 
  replaces 
  lunaedactyla 
  in 
  the 
  French 
  Alps 
  —

   Larche, 
  in 
  the 
  Basses-

  up 
  to 
  Mont 
  Blanc

  these 
  spines 
  are 
  not 
  

   only 
  shortened 
  and 
  lose 
  something 
  of 
  the

  one

   on 
  the 
  other 
  side,

  much 
  shorter,

  The 
  genus 
  Marasmarcha, 
  as 
  we 
  have 
  already 
  noted 
  (antea, 
  p. 
  885), 
  

   was 
  created 
  by 
  Meyrick 
  for 
  phaeodactyla, 
  Hb. 
  (lunaedactyla, 
  Haw.), 
  and 
  

   liophanes, 
  Meyr., 
  a 
  species 
  from 
  Reunion 
  (Trans. 
  Ent. 
  Soc. 
  London, 
  

   1886, 
  p. 
  11). 
  His 
  diagnosis 
  reads 
  : 
  — 
  

  

  Forehead 
  with 
  projecting 
  tuft 
  of 
  scales. 
  Antennae 
  of 
  <$ 
  ciliated. 
  Palpi 
  

   moderate, 
  ascending, 
  slender, 
  terminal 
  joint 
  moderate, 
  pointed. 
  Tibia? 
  simple. 
  

   Forewings 
  bifid, 
  cleft 
  from 
  before 
  two-thirds, 
  2 
  from 
  near 
  angle, 
  3 
  and 
  4 
  from 
  point 
  

   of 
  angle 
  or 
  stalked, 
  5 
  and 
  6 
  short, 
  7 
  from 
  near 
  below 
  angle, 
  8 
  and 
  9 
  stalked, 
  10 
  

   absent, 
  11 
  from 
  near 
  angle. 
  Hindwings 
  trifid, 
  3rd 
  segment 
  without 
  black 
  scales 
  in 
  

   cilia; 
  2 
  from 
  before 
  middle 
  of 
  cell, 
  3 
  and 
  4 
  short-stalked, 
  5 
  and 
  6 
  very 
  short, 
  7 
  and 
  

   8 
  divergent 
  from 
  beyond 
  cleft 
  — 
  phaeodactyla, 
  Hb., 
  liophanes, 
  Meyr. 
  

  

  In 
  1890, 
  he 
  gave 
  a 
  slightly 
  modified 
  diagnosis 
  [pp. 
  cit., 
  p. 
  488) 
  

   which 
  reads 
  thus 
  : 
  — 
  

  

  Face 
  with 
  more 
  or 
  less 
  projecting 
  tuft; 
  ocelli 
  obsolete; 
  tongue 
  developed. 
  

   Antenna; 
  two-thirds, 
  in 
  c? 
  ciliated 
  (one-third). 
  Labial 
  palpi 
  moderate, 
  ascending, 
  

   slender, 
  terminal 
  joint 
  moderate, 
  pointed. 
  Maxillary 
  palpi 
  obsolete. 
  Tibiag 
  

   pimple, 
  outer 
  spurs 
  nearly 
  equal 
  inner. 
  Forewings 
  bifid, 
  cleft 
  from 
  before 
  two- 
  

   thirds 
  ; 
  vein 
  2 
  from 
  near 
  angle, 
  3 
  and 
  4 
  from 
  a 
  point 
  or 
  stalked.

  and 
  6

  8, 
  8 
  and 
  9 
  stalked, 
  10 
  absent, 
  11 
  from 
  near 
  angle. 
  Hindwings 
  trifid,

  without 
  black

  Hb. 
  

  

  The 
  inclusion 
  of 
  microdactyla, 
  Hb., 
  in 
  the 
  genus 
  made 
  it 
  so 
  hetero- 
  

   typical 
  that, 
  in 
  1892, 
  wo 
  thought 
  it 
  advisable 
  to 
  restrict 
  the 
  genus 
  to 
  

   lunaedactyla 
  (Brit. 
  Nat., 
  ii., 
  p. 
  61).

  Handbook

  487, 
  he 
  still 
  maintained 
  the 
  genus 
  for 
  these 
  two 
  isolated

  Characterised 
  by 
  the 
  extension 
  of 
  the 
  white 
  markings 
  along 
  the 
  disc 
  of 
  the 
  

  

  wing 
  to 
  (nearly) 
  the 
  base, 
  and 
  the 
  general 
  very 
  pale 
  coloration 
  (see

   vol. 
  xviii., 
  p. 
  178).
