  The 
  $ 
  of 
  Tabanus 
  fumidus 
  likewise 
  somewhat 
  resembles 
  that 
  of 
  T. 
  accensus, 
  

   Austen 
  (Bull. 
  Ent. 
  Res., 
  x, 
  pt. 
  3, 
  p. 
  309, 
  figs. 
  11, 
  12, 
  April 
  1920), 
  from 
  which, 
  on 
  the 
  

   other 
  hand, 
  it 
  may 
  be 
  distinguished 
  at 
  once 
  by 
  the 
  absence 
  of 
  eye-bands 
  and 
  of 
  definite 
  

   thoracic 
  stripes, 
  and 
  by 
  the 
  presence 
  of 
  an 
  appendix 
  to 
  the 
  anterior 
  branch 
  of 
  the 
  

   third 
  longitudinal 
  vein.

  pallidipes, 
  Austen 
  {ibid.,

  — 
  a 
  species 
  which, 
  

   like 
  T. 
  accensus, 
  Austen, 
  has 
  as 
  yet 
  been 
  met 
  with 
  only 
  in 
  Palestine 
  — 
  that 
  of

  is 
  distinguishable 
  forthwith 
  by 
  its 
  much 
  broader 
  front.
