  Aug. 
  20, 
  1918. 
  — 
  " 
  This 
  month 
  has 
  already 
  produced 
  several 
  

   inches 
  (between 
  4 
  and 
  5) 
  of 
  cold 
  rain, 
  and 
  the 
  ordinary 
  dry- 
  

   season 
  forms 
  seem 
  unaffected 
  by 
  it, 
  either 
  on 
  their 
  upper 
  or 
  

   undersides. 
  For 
  instance, 
  I 
  took 
  P. 
  dardanus 
  of 
  the 
  usual 
  

   mewpe, 
  Cr., 
  form 
  and 
  a 
  second 
  example 
  as 
  lightly 
  marked 
  as 
  

   that 
  of 
  antinorii, 
  Oberth., 
  ^. 
  On 
  the 
  other 
  hand, 
  the 
  excessive 
  

   wet 
  of 
  our 
  last 
  summer 
  (December, 
  January, 
  and 
  February) 
  did 
  

   produce 
  more 
  heavily 
  marked 
  forms. 
  P. 
  dardanus 
  tibullus, 
  

   Kirby, 
  were 
  quite 
  common. 
  I 
  will 
  send 
  you 
  dated 
  specimens 
  

   later. 
  I 
  must 
  say 
  I 
  had 
  hoped 
  to 
  procure 
  some 
  extreme 
  forms 
  

   of 
  melanism 
  under 
  the 
  abnormal 
  weather 
  conditions, 
  and 
  so 
  

   far 
  I 
  am 
  disappointed." 
  After 
  referring 
  to 
  the 
  two 
  leighi 
  $ 
  

   forms 
  of 
  dardanus 
  Mr. 
  Barker 
  continued 
  : 
  " 
  Hippocoon, 
  F., 
  $ 
  

   has 
  remained 
  throughout 
  last 
  summer 
  and 
  even 
  till 
  now 
  as 
  

   numerous 
  or 
  more 
  so 
  than 
  cenea, 
  Stoll, 
  $. 
  Trophonius, 
  Westw., 
  

   $ 
  has 
  also 
  been 
  unusually 
  common."

  " 
  The 
  only 
  thing 
  I 
  can 
  recall 
  at 
  present 
  

   (I 
  am 
  writing 
  this 
  at 
  home) 
  of 
  interest 
  to 
  tell 
  you, 
  is 
  the 
  

   capture 
  on 
  October 
  18th 
  of 
  a 
  Papilio 
  dardanus 
  of 
  the 
  female 
  

   form 
  leighi, 
  Poult., 
  with 
  rich 
  orange 
  ochreous 
  markings 
  on 
  

   the 
  upper 
  and 
  lighter 
  on 
  the 
  lower 
  wings. 
  Last 
  season 
  I 
  

   saw 
  two 
  of 
  this 
  form 
  within 
  a 
  few 
  weeks 
  of 
  one 
  another, 
  but 
  

   failed 
  to 
  capture 
  them. 
  These 
  are 
  the 
  only 
  occasions 
  I 
  have 
  

   come 
  across 
  the 
  leighi 
  female 
  in 
  life, 
  and 
  all 
  three 
  of 
  them 
  were 
  

   observed 
  by 
  me 
  within 
  a 
  radius 
  of 
  about 
  a 
  quarter 
  of 
  a 
  mile. 
  

   It 
  seems 
  like 
  a 
  case 
  of 
  a 
  single 
  family 
  breeding 
  true 
  to 
  this 
  

   very 
  rare 
  coloration." 
  

  

  Mr. 
  Barker 
  had 
  also 
  figured 
  two 
  examples 
  of 
  the 
  leighi 
  

   form 
  in 
  " 
  Annals 
  Durban 
  Museum," 
  vol. 
  ii, 
  PI. 
  vii, 
  figs. 
  13, 
  14 
  

   (1917). 
  No. 
  13 
  bore 
  the 
  date 
  May 
  3, 
  1900; 
  No. 
  14 
  was 
  bred 
  

   by 
  Mr. 
  G. 
  F. 
  Leigh 
  on 
  Oct. 
  19, 
  1910. 
  Both 
  were 
  in 
  the 
  Durban 
  

   Museum. 
  Prof. 
  Poulton 
  said 
  that 
  he 
  could 
  not 
  believe 
  that 
  

   climatic 
  influences 
  provided 
  the 
  stimuli 
  for 
  the 
  production 
  of 
  

   the 
  heavily 
  or 
  lightly 
  marked 
  males 
  of 
  dardanus. 
  Thus, 
  the 
  

   moist 
  equatorial 
  belt 
  of 
  Uganda, 
  in 
  which 
  only 
  the 
  wet 
  forms 
  

   of 
  certain 
  Precis 
  occurred 
  all 
  the 
  year 
  round, 
  produced 
  lightly
