  ERNEST 
  E. 
  AUSTEN. 
  

  

  Lower 
  Jordan 
  Valley 
  and 
  Jerusalem 
  : 
  type 
  from 
  Wadi 
  el 
  Kelt, 
  Jericho 
  Plain, 
  

   ll.vi.1918 
  ; 
  a 
  second 
  specimen 
  labelled 
  "Jerusalem," 
  received 
  in 
  1912 
  from 
  the 
  

   Zoologisches 
  Museum, 
  Berlin. 
  

  

  The 
  species 
  just 
  described, 
  individuals 
  of 
  which, 
  as 
  will 
  have 
  been 
  seen, 
  sometimes 
  

   show 
  considerable 
  variation 
  in 
  size, 
  appears 
  to 
  be 
  allied 
  to 
  the 
  Austrian 
  Tabanus 
  

   mikii, 
  Brauer, 
  from 
  which 
  however 
  it 
  is 
  distinguishable, 
  inter 
  alia, 
  by 
  the 
  much 
  

   paler 
  legs 
  ; 
  in 
  T. 
  mikii 
  the 
  femora, 
  front 
  tarsi 
  and 
  tips 
  of 
  the 
  front 
  tibiae 
  are 
  black.

  of

  from

  ; 
  a, 
  antenna 
  from 
  

  

  the 
  side, 
  greatly 
  enlarged. 
  

  

  Tabanus 
  pallidipes 
  is 
  possibly 
  identical 
  with 
  the 
  Arabian 
  T. 
  arabicus, 
  Macq., 
  

   in 
  which 
  the 
  femora 
  were 
  stated 
  by 
  Macquart 
  (Mem. 
  Soc. 
  Roy. 
  Lille, 
  1838, 
  p. 
  299; 
  

   Dipt. 
  Exot., 
  i, 
  2, 
  1838, 
  p. 
  183) 
  to 
  be 
  tawny 
  or 
  fawn-coloured 
  (fauves). 
  The 
  original 
  

   description 
  of 
  this 
  species, 
  however, 
  which 
  makes 
  no 
  mention 
  of 
  the 
  dimensions 
  of 
  

   the 
  front 
  in 
  the 
  $ 
  and 
  leaves 
  the 
  abdominal 
  markings 
  to 
  the 
  imagination 
  of 
  the 
  

   reader, 
  is 
  so 
  brief 
  and 
  faulty 
  that, 
  in 
  the 
  absence 
  of 
  the 
  typical 
  specimens, 
  precise 
  

   identification 
  is 
  impossible.
