  Two

  May 
  1908,

  remarks 
  that 
  South 
  European 
  examples 
  of 
  Tahanus 
  autumnalis 
  

   are 
  on 
  the 
  whole 
  decidedly 
  smaller 
  than 
  specimens 
  from 
  Germany 
  and 
  Northern 
  

   Europe. 
  The 
  respective 
  lengths 
  of 
  the 
  three 
  individuals 
  from 
  Palestine, 
  recorded 
  

   above, 
  are 
  15*75, 
  15, 
  and 
  19'5 
  mm. 
  ; 
  thus 
  it 
  will 
  be 
  seen 
  that, 
  as 
  compared 
  for 
  

   instance 
  with 
  English 
  representatives 
  of 
  the 
  species 
  under 
  discussion, 
  the 
  two 
  

   former 
  are 
  markedly 
  subnormal 
  in 
  size.
