   The 
  predominance 
  of 
  pale 
  hair 
  on 
  the 
  front 
  in 
  the 
  $, 
  the 
  pale 
  second 
  antennal 
  

   joint, 
  and 
  the 
  markings 
  of 
  the 
  dorsum 
  of 
  the 
  abdomen 
  and 
  of 
  the 
  discal 
  cell 
  in 
  the 
  

   wing 
  — 
  the 
  latter 
  agreeing 
  with 
  those 
  seen 
  in 
  the 
  wing 
  of 
  Haematopota 
  pluvialis, 
  

   Linn. 
  — 
  will 
  serve 
  to 
  distinguish 
  the 
  species 
  described 
  above, 
  at 
  least 
  in 
  the 
  female 
  

   sex, 
  from 
  H. 
  crassicornis, 
  Whlbg., 
  with 
  which 
  it 
  agrees 
  in 
  the 
  absence 
  of 
  a 
  groove- 
  

   like 
  constriction 
  before 
  the 
  distal 
  extremity 
  of 
  the 
  first 
  joint 
  of 
  the 
  antennae. 
  

  

  So 
  far 
  as 
  it 
  is 
  possible 
  to 
  judge 
  from 
  the 
  original 
  description 
  of 
  Haematopota 
  

   fallens, 
  Lw., 
  the 
  typical 
  specimens 
  of 
  which 
  were 
  obtained 
  in 
  Turkestan,
