  The 
  species 
  just 
  described 
  is 
  allied 
  to 
  Haematopota 
  pluvialis, 
  Linn., 
  and 
  H. 
  seivelli, 
  

  

  Austen, 
  but 
  is 
  distinguished 
  from 
  both 
  in 
  the 
  female 
  sex 
  by 
  the 
  first 
  joint 
  of 
  the 
  

  

  antenna 
  being 
  less 
  swollen 
  and 
  more 
  elongate, 
  with 
  the 
  groove-like 
  constriction 
  

  

  before 
  the 
  distal 
  extremity 
  less 
  sharply 
  marked, 
  although 
  the 
  extremity 
  itself 
  is 
  

  

  narrowed. 
  Haematopota 
  innominata, 
  $, 
  is 
  further 
  distinguished 
  from 
  H. 
  sewelli, 
  

  

  ?, 
  by 
  the 
  dorsum 
  of 
  the 
  abdomen 
  being 
  blacker, 
  owing 
  to 
  the 
  much 
  less 
  extensive
