  entirely 
  waterless, 
  on 
  the 
  edge 
  of 
  a 
  desert 
  region, 
  and 
  there 
  was 
  no 
  obvious 
  

   breeding-place 
  whence 
  the 
  flies 
  could 
  have 
  come, 
  nearer 
  than 
  an 
  occasional 
  damp 
  

   hollow 
  among 
  the 
  sand-dunes 
  near 
  the 
  coast, 
  several 
  miles 
  further

  The 
  

   author 
  twice 
  took 
  2$ 
  inside 
  his 
  tent 
  at 
  dusk, 
  and 
  at

  time

   was 
  bitten 
  on 
  the 
  hand 
  by 
  a 
  third 
  specimen 
  in 
  the 
  open 
  ; 
  on 
  another 
  occasion 
  

   (26.ix.1917) 
  an 
  officer 
  was 
  attacked 
  by 
  one 
  of 
  these 
  flies, 
  while 
  sitting 
  inside 
  a 
  mess- 
  

   shelter 
  constructed 
  of

  matting. 
  

  

  In 
  size, 
  general 
  appearance, 
  general 
  coloration, 
  and 
  in 
  the 
  pattern 
  of 
  its 
  

   abdominal 
  markings, 
  Tabanus 
  arenivagus 
  somewhat 
  resembles 
  T. 
  pulverifer, 
  

   Walk., 
  the 
  typical 
  series 
  of 
  which 
  was 
  obtained 
  at 
  Baghdad. 
  The 
  species 
  described 
  

   above, 
  however, 
  is 
  distinguished 
  from 
  T. 
  -pulverifer 
  , 
  inter 
  alia, 
  by 
  the 
  presence 
  

   of 
  a 
  shining 
  band 
  on 
  the 
  frontal 
  triangle 
  of 
  the 
  $ 
  and 
  subcallus 
  of 
  the 
  $ 
  ; 
  by 
  the 
  

   lower 
  frontal 
  callus 
  in 
  the 
  $ 
  being 
  paler, 
  and 
  usually 
  smaller 
  and 
  less 
  sharply 
  

   defined 
  ; 
  by 
  the 
  presence 
  in 
  the 
  $ 
  of 
  a 
  relatively 
  large, 
  well-marked, 
  subquadrate
