  all 
  the 
  segments 
  in 
  an 
  evanescent 
  form 
  ; 
  on 
  the 
  1st, 
  2nd 
  and 
  3rd 
  ab- 
  

   dominals 
  the 
  ridges 
  are 
  broad 
  and 
  flat, 
  further 
  apart 
  on 
  each 
  segment, 
  and 
  

   on 
  its 
  hinder 
  margin, 
  where 
  they 
  form 
  a 
  low 
  prominence. 
  To 
  return 
  to 
  the 
  

   thorax, 
  where, 
  only, 
  they 
  are 
  a 
  prominent 
  feature, 
  each 
  is 
  divided 
  by 
  

   transverse 
  lines 
  into 
  a 
  slightly 
  beaded 
  structure, 
  and, 
  together, 
  they 
  

   form 
  a 
  great 
  prominence 
  on 
  the 
  posterior 
  margin 
  of 
  the 
  mesothorax. 
  

   The 
  same 
  transverse 
  lines, 
  that 
  form 
  the 
  beaded 
  structure 
  on 
  the 
  

   thorax, 
  exist 
  all 
  round 
  the 
  abdominal 
  segments, 
  as 
  far 
  back 
  as 
  the 
  

   intersegmental 
  membrane, 
  and 
  are 
  eleven 
  or 
  twelve 
  in 
  number. 
  On 
  

   the 
  2nd 
  abdominal 
  segment, 
  they 
  are 
  about 
  twenty 
  on 
  the 
  segment 
  

   proper, 
  and 
  ten 
  or 
  twelve 
  on 
  the 
  posterior 
  subsegment 
  that 
  appears 
  to 
  

   correspond 
  with 
  the 
  intersegmental 
  membrane 
  of 
  free 
  segments. 
  A 
  

   conspicuous 
  white 
  stripe 
  passes 
  subspiracularly 
  along 
  the 
  abdomen, 
  

   and 
  is 
  on 
  a 
  slightly 
  raised 
  surface. 
  Green 
  lines 
  exist 
  dorsally, 
  sub- 
  

   dorsally 
  in 
  a 
  slight 
  hollow 
  below 
  the 
  dorsal 
  ridges, 
  and 
  a 
  slightly 
  

   whiter 
  line 
  below 
  this. 
  The 
  spiracles 
  are 
  faintly 
  raised 
  rings 
  with 
  

   hardly 
  darker 
  margins. 
  The 
  wings 
  have 
  the 
  nervures 
  well 
  marked 
  in 
  

   whitish 
  raised 
  lines, 
  rather 
  broad 
  and 
  rounded 
  ; 
  all 
  the 
  nervures 
  

   shown 
  are 
  simple, 
  except 
  the 
  median, 
  which 
  has 
  three 
  branches, 
  and 
  

   what 
  looks 
  like 
  the 
  subcostal, 
  but 
  is 
  really, 
  no 
  doubt, 
  one 
  portion 
  of 
  

   the 
  radial, 
  which 
  has 
  two. 
  The 
  margin 
  beyond 
  " 
  Poulton's 
  line 
  " 
  is 
  

   well 
  marked, 
  and 
  reaches 
  as 
  a 
  fine 
  point 
  to 
  the 
  apex 
  just 
  beyond 
  the 
  edge 
  of 
  

   the 
  3rd 
  abdominal 
  segment. 
  The 
  3rd 
  legs 
  extend 
  beyond 
  the 
  margin 
  of 
  

   the 
  4th 
  abdominal, 
  and 
  the 
  2nd 
  legs 
  are 
  a 
  little 
  shorter. 
  The 
  antennae 
  

   do 
  not 
  reach 
  half 
  way, 
  but, 
  not 
  being 
  in 
  their 
  grooves, 
  their 
  relations 
  are 
  

   not 
  correctly 
  shown. 
  [Described 
  June 
  14th, 
  1899, 
  from 
  pupa 
  found 
  

   wild 
  by 
  Raynor, 
  near 
  Maldon.] 
  The 
  pupa 
  is 
  a 
  little 
  over 
  -5 
  inch 
  long, 
  

   and 
  exactly 
  of 
  the 
  shape 
  of 
  that 
  of 
  G. 
  ochrodactyla 
  as 
  described 
  by 
  

   Buckler 
  (antea, 
  p. 
  232), 
  though, 
  perhaps, 
  a 
  little 
  stouter, 
  as 
  it 
  can 
  

   hardly 
  be 
  called 
  " 
  slender," 
  the 
  word 
  applied 
  by 
  Buckler 
  to 
  that 
  species. 
  

   It 
  has 
  a 
  longish 
  beak 
  in 
  front, 
  projecting 
  at 
  a 
  slight 
  angle 
  down- 
  

   wards 
  from 
  the 
  head, 
  pointed 
  at 
  the 
  tail 
  ; 
  the 
  wing-cases 
  of 
  moderate 
  

   length, 
  well-developed, 
  and 
  the 
  ends 
  of 
  the 
  leg-cases 
  projecting 
  free 
  

   from 
  the 
  abdomen. 
  The 
  colour 
  is 
  bright 
  pale 
  green, 
  dorsal 
  line 
  

   darker 
  green, 
  edged 
  on 
  the 
  thorax 
  with 
  white 
  ; 
  beak 
  white 
  above, 
  rust- 
  

   colour 
  at 
  the 
  sides 
  ; 
  there 
  is 
  also 
  a 
  conspicuous 
  streak 
  of 
  this 
  rust- 
  

   colour 
  on 
  the 
  hind 
  part 
  of 
  the 
  thorax, 
  and 
  the 
  same 
  colour 
  also 
  appears 
  

   (but 
  more 
  faintly) 
  on 
  the 
  abdominal 
  point, 
  and 
  at 
  the 
  tips 
  of 
  the 
  

   leg-cases 
  ; 
  subdorsal 
  line 
  dark 
  green, 
  lateral 
  line 
  white. 
  Ventral 
  

   surface 
  pale 
  green 
  with 
  darker 
  green 
  lines, 
  and 
  the 
  wing-cases 
  with 
  

   whitish 
  rays 
  (Porritt). 
  

  

  Time 
  of 
  appearance. 
  — 
  The 
  species 
  is 
  single-brooded, 
  occurring 
  in 
  

   June 
  and 
  July, 
  and, 
  in 
  late 
  seasons, 
  odd 
  specimens 
  are 
  occasionally 
  

   taken 
  in 
  August, 
  but, 
  on 
  the 
  whole, 
  the 
  species 
  is 
  considerably 
  earlier 
  

   than 
  G. 
  ochrodactyla, 
  which 
  rarely 
  occurs 
  before 
  July, 
  ami 
  frequently 
  

   is 
  found 
  in 
  August 
  ; 
  Reid 
  also 
  observes 
  that, 
  in 
  Aberdeenshire. 
  G 
  . 
  palli- 
  

   dactyla 
  occurs 
  in 
  June 
  and 
  July. 
  This 
  time 
  is 
  apparently 
  conditioned 
  

   by 
  the 
  flowering 
  of 
  the 
  respective 
  foodplants. 
  In 
  America, 
  Pernald 
  notes 
  

   it 
  as 
  occurring 
  on 
  June 
  24th, 
  in 
  Maine; 
  June 
  10th 
  27th, 
  in 
  Massa- 
  

   chusetts; 
  June 
  23rd 
  to 
  July 
  17th, 
  in 
  New 
  York; 
  May. 
  in 
  Missouri; 
  

   June 
  llth-lGth, 
  in 
  Colorado; 
  June 
  1st- 
  18th, 
  in 
  California. 
  Stange 
  

   observes 
  that, 
  near 
  Friedland, 
  the 
  imago 
  appears 
  to 
  tlv 
  somewhat 
  

   earlier 
  than 
  G. 
  ochrodactyla; 
  in 
  the 
  Hamburg 
  district, 
  it 
  occurs
