  Prof. 
  Poulton 
  drew 
  the 
  attention 
  of 
  the 
  Fellows 
  to 
  observa- 
  

   tions 
  made 
  on 
  this 
  hornet 
  in 
  Palestine 
  by 
  Mr. 
  C. 
  H. 
  Hamm, 
  

   late 
  R.A.F. 
  The 
  insects 
  were 
  abundant 
  in 
  the 
  Ramleh 
  district, 
  

   from 
  July 
  to 
  October, 
  1918 
  : 
  they 
  were 
  also 
  seen, 
  singly, 
  visiting 
  

   a 
  large 
  Umbelliferous 
  plant 
  in 
  April 
  and 
  May. 
  They 
  were 
  

   never 
  seen 
  to 
  catch 
  other 
  insects. 
  They 
  nested 
  in 
  the 
  ground. 
  

   When 
  they 
  became 
  common, 
  the 
  workers 
  in 
  large 
  numbers 
  

   visited 
  the 
  mess-tents, 
  feeding 
  on 
  jam 
  and 
  other 
  sweet 
  foods. 
  

   When 
  so 
  occupied 
  they 
  were 
  often 
  knocked 
  down 
  — 
  sometimes 
  

   stunned, 
  sometimes 
  killed. 
  It 
  was 
  then 
  observed 
  that 
  other 
  

   hornets 
  would 
  examine 
  the 
  bodies 
  lying 
  on 
  the 
  ground 
  and 
  

   carry 
  off, 
  generally 
  after 
  considerable 
  effort 
  in 
  rising 
  from 
  the 
  

   ground, 
  those 
  that 
  were 
  still 
  alive. 
  The 
  dead 
  were 
  always 
  

   left 
  as 
  they 
  lay. 
  

  

  The 
  MIMETIC 
  ASSOCIATION 
  BETWEEN 
  TWO 
  SPECIES 
  OF 
  

  

  Euploea 
  and 
  ONE 
  Danaine 
  in 
  Fiji. 
  — 
  Prof. 
  Poulton 
  said 
  

   that 
  ever 
  since 
  1899 
  when 
  he 
  had 
  received 
  examples 
  of 
  the 
  

   two 
  common 
  Fijian 
  Euploeas, 
  Nipara 
  eleutlio, 
  Quoy, 
  and 
  

   Deragena 
  proserpina, 
  Butl., 
  collected 
  at 
  the 
  same 
  time 
  and 
  

   place 
  by 
  his 
  friend 
  Prof. 
  Gustav 
  Gilson, 
  he 
  had 
  longed 
  for 
  

   the 
  opportunity 
  of 
  studying 
  a 
  long 
  series. 
  In 
  the 
  meantime 
  

   his 
  friend 
  Mr. 
  J. 
  C. 
  Moulton 
  had 
  figured 
  both 
  species 
  from 
  

   the 
  Gilson 
  series 
  and 
  had 
  given 
  an 
  account 
  of 
  the 
  mimetic 
  

   modification 
  in 
  the 
  pattern 
  of 
  proserpina 
  (Trans. 
  Ent. 
  Soc, 
  

   1908, 
  p. 
  603, 
  PI. 
  XXXIV, 
  figs. 
  4, 
  9). 
  The 
  interpretation 
  

   adopted 
  in 
  Mr. 
  Moulton 
  's 
  paper 
  was 
  criticised 
  by 
  Col. 
  Manders 
  

   in 
  the 
  " 
  Entomologist's 
  Record 
  " 
  for 
  May 
  1909 
  (pp. 
  120, 
  121) 
  

   and 
  defended 
  by 
  the 
  present 
  writer 
  in 
  Proc. 
  Ent. 
  Soc, 
  1909, 
  

   pp. 
  xxxvii, 
  xxxviii. 
  

  

  Prof. 
  Poulton 
  had 
  recently 
  received 
  a 
  fine 
  set 
  of 
  these 
  two 
  

   Euploeas 
  taken

  Mr.
