  BRITISH 
  LEPIDOPTERA. 
  

  

  directed 
  ventrally. 
  The 
  maxillae 
  reach 
  to 
  half 
  the 
  length 
  of 
  the 
  

   wings, 
  the 
  antennas 
  to 
  three-fourths, 
  and 
  the 
  1st 
  legs 
  fall 
  just 
  short 
  

   of 
  the 
  wings. 
  The 
  neuration 
  of 
  the 
  wings 
  is 
  strongly 
  marked 
  by 
  pale 
  

   ridges 
  (Chapman, 
  May 
  29th, 
  1904). 
  Pale 
  green 
  with 
  an 
  obscure 
  

   reddish-pink 
  dorsal 
  line 
  or 
  stripe, 
  which, 
  in 
  some 
  examples, 
  is 
  only 
  

   represented 
  by 
  short 
  dashes 
  behind 
  the 
  thorax 
  and 
  on 
  the 
  last 
  four 
  

   segments 
  ; 
  the 
  anal 
  segment 
  and 
  tip 
  of 
  leg-cases 
  pale 
  pinkish 
  ; 
  

   sometimes 
  the 
  whole 
  of 
  the 
  dorsal 
  area 
  is 
  also 
  suffused 
  with 
  pinkish 
  ; 
  

   wing-cases 
  tinged 
  with 
  yellowish 
  ; 
  leg-cases 
  detached 
  from 
  the 
  

   abdomen 
  (South). 
  

  

  Time 
  of 
  appearance. 
  — 
  The 
  species 
  appears 
  to 
  be 
  double- 
  or 
  treble- 
  

   brooded, 
  according 
  to 
  the 
  season. 
  In 
  forward 
  seasons, 
  larvae, 
  collected 
  

   in 
  April-May, 
  give 
  imagines 
  in 
  late 
  May 
  and 
  June 
  ; 
  from 
  eggs 
  laid 
  in 
  

   June, 
  imagines 
  may 
  be 
  reared 
  in 
  August; 
  and 
  from 
  eggs 
  laid 
  in 
  August, 
  

   the 
  imagines 
  emerge 
  in 
  late 
  September 
  and 
  October. 
  In 
  backward 
  

   seasons, 
  one 
  finds 
  larvae 
  still 
  feeding 
  throughout 
  May 
  and 
  June, 
  which 
  

   rarely 
  give 
  imagines 
  until 
  late 
  June 
  or 
  early 
  July 
  ; 
  eggs 
  laid 
  in 
  early 
  

   July 
  rarely 
  produce 
  imagines 
  until 
  late 
  August 
  or 
  September, 
  when 
  

   a 
  third 
  brood 
  is 
  rarely 
  attempted. 
  On 
  the 
  continent, 
  in 
  central 
  Europe, 
  

   the 
  same 
  times 
  of 
  appearance 
  are 
  noticed, 
  e.g., 
  Rossler 
  says 
  that, 
  in 
  

   Germany, 
  the 
  imagines 
  appear 
  in 
  the 
  end 
  of 
  April 
  and 
  through 
  May, 
  

   then 
  at 
  the 
  end 
  of 
  July, 
  and 
  on 
  into 
  August, 
  and 
  lastly, 
  in 
  late 
  autumn. 
  

   Reutti 
  states 
  that, 
  in 
  Baden, 
  it 
  is 
  common 
  in 
  May, 
  July, 
  and 
  September. 
  

   Stange 
  says 
  that, 
  in 
  Friedland, 
  the 
  imagines 
  are 
  to 
  be 
  found 
  from 
  the 
  

   end 
  of 
  May 
  to 
  September, 
  apparently 
  in 
  three 
  broods. 
  In 
  Pomerania, 
  

   the 
  insect 
  occurs 
  through 
  tbe 
  summer 
  and 
  on 
  to 
  September 
  (Buttner). 
  

   Speyer 
  observes 
  that, 
  at 
  Waldeck, 
  it 
  occurs 
  in 
  June, 
  and 
  again 
  at 
  the 
  end 
  

   of 
  August 
  and 
  beginning 
  of 
  September. 
  In 
  Silesia, 
  it 
  occurs 
  rather 
  

   rarely 
  in 
  May, 
  then 
  much 
  commoner 
  from 
  the 
  end 
  of 
  July 
  to 
  beginning 
  

   of 
  October 
  (Wocke). 
  At 
  Modling, 
  in 
  Lower 
  Austria, 
  the 
  imagines 
  appear 
  

   in 
  May 
  and 
  June 
  (Mann). 
  In 
  Roumania, 
  it 
  occurs 
  almost 
  everywhere 
  

   in 
  meadows 
  in 
  August 
  (Caradja). 
  In 
  the 
  Baltic 
  Provinces, 
  Nolcken 
  

   notes 
  its 
  occurrence 
  in 
  May 
  and 
  June, 
  again 
  July 
  15th- 
  August 
  8th, 
  and 
  

   yet 
  again 
  September 
  24th. 
  In 
  the 
  mountains, 
  the 
  var. 
  plagiodactylus 
  

   occurs, 
  and 
  appears 
  to 
  have 
  only 
  two 
  broods 
  (at 
  most) 
  in 
  the 
  year. 
  

   We 
  have 
  made 
  no 
  attempt 
  to 
  distinguish 
  in 
  the 
  following 
  dates 
  those 
  

   referring 
  to 
  the 
  type, 
  and 
  those 
  referring 
  to 
  var. 
  plagiodactylus.
