  Owing 
  especially 
  to 
  the 
  ochraceous-tawny 
  or 
  cinnamon-coloured 
  areas 
  on 
  each 
  side 
  

   of 
  the 
  dorsum 
  of 
  the 
  abdomen 
  being 
  unicolorous, 
  i.e., 
  devoid 
  in 
  each 
  case 
  of 
  a 
  longi- 
  

   tudinal 
  series 
  of 
  greyish 
  pollinose 
  or 
  pale-haired 
  oblique 
  blotches, 
  the 
  species 
  described 
  

   above 
  cannot, 
  in 
  the 
  $ 
  sex 
  at 
  least, 
  be 
  confused 
  with 
  any 
  of 
  its 
  congeners 
  known 
  to 
  

   the 
  writer. 
  As 
  regards 
  other 
  characters, 
  although 
  presenting 
  a 
  certain 
  superficial 
  

   resemblance 
  in 
  coloration 
  to 
  Tabanus 
  acuminatus, 
  Lw., 
  which 
  is 
  found 
  in 
  Southern 
  and 
  

   Central 
  Europe 
  and 
  in 
  Siberia, 
  the 
  $ 
  of 
  T. 
  inaequatus, 
  apart 
  from 
  the 
  apex 
  of 
  its 
  

   abdomen 
  not 
  being 
  laterally 
  compressed, 
  is 
  at 
  once 
  distinguishable 
  from 
  that 
  of 
  the 
  

   species 
  mentioned 
  by 
  its 
  bare 
  eyes, 
  much 
  narrower 
  front, 
  much 
  more 
  attenuated 
  dorsal 
  

   abdominal 
  stripe, 
  and 
  pale 
  femora.
