  As 
  a 
  small 
  acknowledgement 
  of 
  much 
  kindness 
  shown 
  to 
  the 
  author, 
  the 
  species 
  

   just 
  described 
  has 
  been 
  named 
  in 
  honour 
  of 
  his 
  friend 
  Lieut. 
  -Col. 
  (temp. 
  Col.) 
  E. 
  P. 
  

   Sewell, 
  C.M.G.,

  (late 
  D.D.M.S.,

  Corps,

  So 
  far 
  as 
  

   the 
  experience 
  of 
  1918 
  warrants 
  such 
  a 
  conclusion, 
  Haematopota 
  sewelli 
  would 
  

   appear 
  to 
  be 
  the 
  commonest 
  representative 
  of 
  its 
  genus 
  in 
  Palestine. 
  The 
  remark- 
  

   able 
  habit 
  of 
  the 
  males, 
  referred 
  to 
  above, 
  of 
  remaining 
  poised 
  in 
  the 
  air 
  like 
  Hover 
  - 
  

   flies, 
  although 
  new 
  to 
  the 
  present 
  writer, 
  would 
  seem 
  to 
  be 
  a 
  generic 
  character, 
  

   since 
  Schiner 
  (Fauna 
  Austriaca. 
  Die 
  Fliegen 
  (Diptera), 
  I. 
  Theil, 
  1862, 
  p. 
  38), 
  

   at 
  the 
  end 
  of 
  his 
  notes 
  on 
  the 
  genus 
  Haematopota, 
  remarks 
  : 
  — 
  " 
  The 
  males 
  too 
  

   hover 
  in 
  the 
  air 
  in 
  the 
  morning 
  and 
  towards 
  evening."
