  resembles 
  that 
  species 
  in 
  general 
  appearance, 
  width 
  of 
  front 
  in 
  $, 
  and 
  size. 
  

   T. 
  unicinctus 
  is 
  however 
  distinguishable, 
  inter 
  alia, 
  by 
  the 
  veins 
  in 
  the 
  centre 
  of 
  the 
  

   wing 
  being 
  suffused 
  with 
  brown, 
  by 
  the 
  presence 
  of 
  a 
  dark 
  brown 
  stigma, 
  and 
  by 
  

   the 
  ground 
  colour 
  of 
  the 
  legs, 
  with 
  exception 
  of 
  a 
  pale 
  ring 
  at 
  the 
  base 
  of 
  the 
  front 
  

   tibiae, 
  being 
  entirely 
  black. 
  

  

  Finally 
  it 
  may 
  be 
  mentioned 
  that 
  Tabanus 
  leleani 
  is 
  nearly 
  allied 
  to 
  T. 
  unifasciatus 
  

   Lw., 
  but 
  may 
  be 
  distinguished 
  by 
  the 
  sharply 
  marked 
  contrast 
  in 
  size 
  between 
  the 
  

   large 
  and 
  small 
  facets 
  in 
  the 
  eyes 
  of 
  the 
  <J, 
  and 
  by 
  the 
  greater 
  length 
  and 
  blunter 
  

   termination 
  of 
  the 
  purple 
  eye 
  band 
  in 
  the
