  BEITISH 
  LEPIDOPTERA. 
  

  

  to 
  their 
  heavier 
  and 
  less 
  even 
  appearance, 
  their 
  surface 
  being 
  roughened 
  

   and 
  spiculate. 
  The 
  meso- 
  and 
  metathoracic 
  segments 
  also 
  bear 
  a 
  

   dorsal 
  ridge 
  of 
  hair-like 
  horns, 
  but 
  the 
  real 
  tubercular-based 
  hairs 
  are 
  

   as 
  in 
  M. 
  lunaedacti/la, 
  four 
  dorsal 
  on 
  the 
  meso- 
  and 
  two 
  on 
  the 
  

   metathorax, 
  each 
  segment 
  having 
  two 
  lateral 
  hairs 
  at 
  the 
  base 
  of 
  the 
  

   wings, 
  also 
  as 
  in 
  the 
  above-named 
  species. 
  The 
  abdominal 
  segments, 
  

   especially 
  the 
  4th, 
  5th, 
  and 
  6th, 
  on 
  their 
  dorsal 
  area, 
  show 
  the 
  transverse 
  

   wrinklings 
  of 
  the 
  integument 
  very 
  sharply 
  ; 
  they 
  are 
  fine 
  and 
  even, 
  and 
  

   appear 
  as 
  flattened 
  folds. 
  The 
  intersegmental 
  area 
  is 
  very 
  finely, 
  but 
  

   sharply, 
  pitted. 
  It 
  is 
  interesting 
  to 
  note 
  that 
  this 
  genus 
  retains 
  the 
  

   wing, 
  and 
  antennal, 
  hair-fringes 
  that 
  are 
  lostinilf. 
  lunaedactyla. 
  The 
  

   development 
  of 
  hair-like 
  processes 
  in 
  proximity 
  to 
  the 
  tubercular 
  hairs, 
  

   in 
  this 
  species, 
  suggests 
  that 
  perhaps 
  the 
  additional 
  hairs 
  of 
  species 
  like 
  

   Ovendenia 
  septodactyla, 
  etc., 
  may 
  be 
  of 
  the 
  same 
  character, 
  but 
  a 
  further 
  

   examination 
  of 
  the 
  last-named 
  species 
  shows 
  that 
  there 
  is 
  not 
  the 
  

   same 
  clear 
  differentiation, 
  and, 
  as 
  regards 
  the 
  dorsal 
  groups, 
  the 
  two 
  

   large 
  central 
  structures 
  are 
  most 
  certainly 
  hairs 
  (Eacot). 
  

  

  Variation 
  of 
  pupa. 
  — 
  The 
  pupa?, 
  like 
  the 
  larvae, 
  vary 
  somewhat 
  in 
  

   colour, 
  being 
  sometimes 
  pale 
  pinkish, 
  at 
  other 
  times 
  pale 
  green, 
  and 
  

   occasionally 
  brown, 
  with 
  intermediate 
  varieties, 
  but 
  the 
  pale 
  forms 
  all 
  

   become 
  darker 
  before 
  emergence. 
  

  

  Time 
  of 
  appearance. 
  — 
  The 
  species 
  is 
  on 
  the 
  wing, 
  in 
  most 
  years, 
  

   from 
  mid-June 
  till 
  towards 
  the 
  end 
  of 
  July, 
  although, 
  in 
  such 
  early 
  

   years 
  as 
  1893, 
  imagines 
  were 
  already 
  on 
  the 
  wing 
  before 
  the 
  end 
  of 
  

   May, 
  and 
  in 
  late 
  years 
  specimens 
  are 
  to 
  be 
  found 
  in 
  August. 
  In 
  

   Baden, 
  it 
  occurs 
  in 
  the 
  Hardtwald, 
  near 
  Carlsruhe, 
  from 
  the 
  beginning 
  

   of 
  June 
  on

  very 
  abundantly

   scorodonia

   Tauberbischofsheim
