  — 
  Alar 
  expanse 
  7-8 
  lines; 
  head, 
  face, 
  thorax, 
  body, 
  and 
  legs, 
  of 
  a 
  light, 
  

   creamy, 
  ashy-grey, 
  lightest 
  towards 
  the 
  cleft 
  ; 
  very 
  slightly 
  irrorated 
  with 
  darker 
  

   atoms; 
  the 
  discoidal 
  and 
  cleft-spots 
  scarcely 
  perceptible. 
  Underwings 
  rather 
  darker 
  

   than 
  the 
  upperwings. 
  P. 
  hodgkinsonii 
  differs 
  from 
  P. 
  loicei 
  (loeicii), 
  to 
  which 
  it 
  

   is 
  nearly 
  allied, 
  in 
  the 
  general 
  colour 
  being 
  lighter, 
  the 
  less 
  irrorated 
  or 
  suffused 
  

   appearance, 
  its 
  lesser 
  size, 
  and 
  its 
  want 
  of 
  the 
  Jight 
  canary-coloured 
  terminal 
  costal 
  

   edging 
  to 
  the 
  tip, 
  and 
  also 
  in 
  its 
  time 
  of 
  appearance 
  ; 
  from 
  P. 
  plagiodactylus 
  it 
  

   differs 
  in 
  its 
  smaller 
  size, 
  much 
  lighter 
  colour, 
  tbe 
  entire 
  want 
  of 
  the 
  bright 
  buff 
  

   and 
  light 
  ashy-white 
  upon 
  the 
  thorax 
  and 
  body,* 
  the 
  absence 
  of 
  the 
  dark 
  blotches 
  

   so 
  conspicuous 
  upon 
  good 
  specimens 
  of 
  that 
  species, 
  the 
  absence 
  of 
  any 
  light 
  

   edging 
  to 
  the 
  cleft, 
  and 
  in 
  being 
  devoid 
  of 
  any 
  light 
  colour 
  upon 
  the 
  terminal 
  joints 
  

   of 
  the 
  legs 
  ; 
  from 
  P. 
  bipuntidactylus 
  it 
  differs 
  in 
  its 
  smaller 
  size, 
  more 
  yellowish 
  

   ashy-colour 
  and 
  lighter-coloured 
  legs, 
  and 
  from 
  the 
  spurs 
  being 
  of 
  the 
  same 
  colour 
  

   as 
  the 
  legs, 
  those 
  of 
  bipunctidactylus 
  being 
  lighter 
  than 
  the 
  legs. 
  A 
  single 
  specimen 
  

   captured 
  in 
  early 
  June, 
  circa 
  1860, 
  in 
  a 
  small 
  pasture-field 
  at 
  Witherslack 
  (between 
  

   the 
  inn 
  and 
  "moss"); 
  three 
  captured 
  later 
  in 
  the 
  juniper 
  field 
  near, 
  by 
  Hodgkinson, 
  

   of 
  which 
  one 
  each 
  was 
  given 
  to 
  Gregson, 
  Doubleday, 
  and 
  Burney. 
  One 
  or 
  two 
  others 
  

   taken 
  since 
  by 
  Hodgkinson. 
  Very 
  closely 
  allied 
  to 
  P. 
  loicei 
  (loeicii) 
  ; 
  indeed, 
  none 
  

   but 
  a 
  practised 
  eye 
  would 
  detect 
  the 
  differences 
  (Gregson, 
  Ent. 
  Mo. 
  Mag., 
  iv., 
  

   p. 
  178). 
  

  

  Whether 
  this 
  is 
  a 
  form 
  of 
  A. 
  bipunctidactijla 
  or 
  A, 
  zopliodactylus 
  has 
  

   long 
  been 
  a 
  matter 
  of 
  controversy, 
  but, 
  in 
  spite 
  of 
  our 
  remark 
  (Pter. 
  

   Brit., 
  p. 
  95), 
  South 
  was 
  the 
  first 
  British 
  lepidopterist 
  who 
  rightly 
  

   suggested 
  that 
  this 
  insect 
  was 
  a 
  form 
  of 
  bipunctid 
  actyla. 
  That 
  this 
  

   is 
  so, 
  is 
  abundantly 
  proved 
  by 
  the 
  example 
  in 
  the 
  " 
  Doubleday 
  

   collection," 
  mentioned 
  by 
  Gregson 
  (antea), 
  which 
  is 
  an 
  undoubted 
  

   specimen 
  of 
  A. 
  bipunctidactyla, 
  and 
  Bankes 
  observes 
  that 
  he 
  is 
  in 
  

   possession 
  of 
  six 
  examples 
  that 
  stood 
  as 
  "hodgkinsoni" 
  in 
  Hodgkinson's 
  

   own 
  cabinet 
  series 
  ; 
  they 
  are 
  all 
  worn 
  A. 
  bipunctidactyla, 
  and 
  appear 
  to 
  

   have 
  been, 
  when 
  fresh, 
  almost 
  typical 
  examples 
  of 
  the 
  species. 
  He 
  has 
  

   also 
  six 
  others 
  from 
  the 
  " 
  Mason 
  collection," 
  which 
  were 
  also 
  part 
  of 
  

   Hodgkinson's 
  original 
  series, 
  and 
  of 
  these, 
  five 
  are 
  very 
  worn 
  A. 
  bipuncti- 
  

   dactyla, 
  and 
  probably, 
  when 
  fresh, 
  not 
  really 
  paler 
  than 
  typical 
  specimens, 
  

   whilst 
  the 
  remaining 
  one, 
  wasted 
  to 
  a 
  mere 
  shadow, 
  may 
  not 
  be 
  this 
  

   species, 
  and 
  is 
  certainly 
  not 
  A. 
  zopliodactylus. 
  Bankes 
  further 
  observes 
  

   that 
  he 
  examined 
  the 
  whole 
  of 
  the 
  series 
  in 
  Hodgkinson's 
  collection, 
  

   and 
  concluded 
  that 
  all 
  were 
  worn 
  A. 
  bipuntidactyla, 
  some 
  of 
  normal 
  size, 
  

   others 
  small. 
  Hodgkinson 
  himself 
  observes 
  {Ent. 
  Bee, 
  viii., 
  p. 
  190) 
  

   that 
  " 
  there 
  is, 
  in 
  all 
  specimens, 
  a 
  light 
  (very 
  pale) 
  streak 
  on 
  the 
  lower 
  

   side 
  of 
  the 
  upper 
  wing, 
  and 
  the 
  heads 
  of 
  all 
  are 
  of 
  a 
  very 
  pale 
  ash- 
  

   colour, 
  as 
  also 
  are 
  the 
  legs." 
  He 
  further 
  says 
  that 
  he 
  took, 
  " 
  with 
  

   hodykinsoni, 
  some 
  examples 
  of 
  playiodactylus, 
  with 
  the 
  tips 
  more 
  

   hooked." 
  He 
  records 
  the 
  capture 
  of 
  eight 
  examples 
  at 
  Witherslack 
  on 
  

   May 
  19th, 
  1867, 
  three 
  others 
  in 
  1863, 
  and 
  observes 
  that 
  it 
  appears 
  to 
  

  

  * 
  Very 
  indistinct 
  or 
  obsolete 
  in 
  the 
  js 
  of 
  this 
  species.
