  The 
  little 
  paper 
  on 
  the 
  proportion 
  of 
  the 
  female 
  forms 
  of 
  Pafilio 
  

   polytes, 
  L., 
  read 
  and 
  kindly 
  emphasized 
  by 
  Mr. 
  T. 
  Bainbrigge 
  Fletcher 
  

   at 
  the 
  Third 
  Entomological 
  Meeting 
  at 
  Pusa, 
  in 
  February 
  1919 
  (Report, 
  

   Vol. 
  Ill, 
  pp. 
  903-906) 
  has 
  produced 
  a 
  most 
  interesting 
  series 
  of 
  polytes 
  

   captured 
  in 
  1919 
  and 
  1920 
  by 
  Mr. 
  C. 
  M. 
  Inglis 
  at 
  Baghownie, 
  Laheria 
  

   Sarai 
  P. 
  0., 
  B. 
  & 
  N.-W. 
  Ry., 
  towards 
  the 
  south 
  of 
  the 
  Darbhanga 
  District 
  

   of 
  Bihar. 
  I 
  therefore 
  take 
  the 
  opportunity 
  of 
  contributing 
  a 
  prelimi- 
  

   nary 
  study 
  of 
  this 
  material 
  to 
  the 
  Fourth 
  Entomological 
  Meeting 
  at 
  

   Pusa. 
  Furthermore, 
  a 
  fine 
  series 
  captured 
  by 
  Mr. 
  0. 
  C. 
  Ollenbach 
  at 
  

   Dehra 
  Dun, 
  United 
  Provinces, 
  in 
  March 
  1917, 
  only 
  reached 
  me 
  after 
  

   the 
  Third 
  Entomological 
  Meeting 
  had 
  taken 
  place, 
  the 
  captor 
  wisely 
  

   deciding 
  to 
  avoid 
  any 
  unnecessary 
  risks 
  in 
  transport. 
  This 
  series 
  also 
  

   has 
  been 
  studied 
  and 
  the 
  results 
  are 
  submitted 
  together 
  with 
  those 
  

   from 
  Baghownie. 
  

  

  Mr. 
  Inglis' 
  captures 
  were 
  all 
  made 
  within 
  two 
  miles 
  of 
  Baghownie 
  

   and 
  all 
  were 
  taken 
  and 
  sent, 
  whether 
  damaged 
  or 
  not. 
  The 
  injured 
  

   specimens 
  are 
  of 
  great 
  interest 
  being 
  in 
  nearly 
  all 
  cases 
  symmetrically 
  

   shorn, 
  or 
  torn 
  at 
  the 
  anal 
  angle 
  of 
  the 
  hind 
  wing, 
  injuries 
  evidently 
  the 
  

   work 
  of 
  birds 
  or 
  lizards. 
  In 
  a 
  few 
  cases 
  as 
  much 
  as 
  half 
  one 
  or 
  both 
  

   hind 
  wings 
  has 
  been 
  shorn 
  away. 
  In 
  addition 
  to 
  the 
  romulus 
  forms 
  

   recorded 
  in 
  the 
  table 
  on 
  page 
  261, 
  Mr. 
  Inglis 
  captured 
  it 
  on 
  July 
  31, 
  

   1917, 
  and 
  September 
  2nd 
  and 
  9th, 
  1918. 
  Concerning 
  the 
  models 
  he 
  

   wrote 
  on 
  February 
  9th, 
  1920 
  : 
  — 
  

  

  " 
  hector 
  itself 
  is 
  never 
  caught. 
  P. 
  aristolochice 
  is 
  of 
  course, 
  a 
  common 
  

   species 
  here. 
  The 
  earliest 
  I 
  have 
  noticed 
  appears 
  to 
  be 
  May 
  29th, 
  

   but 
  it 
  is 
  not 
  till 
  the 
  middle 
  of 
  July 
  that 
  they 
  can 
  be 
  said 
  to 
  be 
  common. 
  

   August 
  also 
  seems 
  to 
  be 
  the 
  month 
  during 
  which 
  most 
  are 
  got, 
  the 
  same 
  

   as 
  polytes."
