  We 
  have 
  not 
  identified 
  the 
  female 
  of 
  this 
  species 
  but 
  the 
  males 
  are 
  

   rather 
  paler 
  in 
  general 
  color 
  than 
  most 
  of 
  the 
  species, 
  being 
  yellow- 
  

   ish-brown, 
  castaneous 
  on 
  posterior 
  expansion 
  of 
  prothorax, 
  meso- 
  

   and 
  meta-thorax 
  and 
  genitalia; 
  sternites 
  7 
  and 
  8 
  distinctly 
  emargi- 
  

   nate 
  medianly 
  and 
  arcuate 
  laterally 
  ; 
  ninth 
  sternite, 
  or 
  hypopygium, 
  

   with 
  the 
  apical 
  margin 
  triangularly 
  excised 
  medianly 
  (fig.

  be- 
  

   tween 
  the 
  elevated 
  supero-posterior 
  angles, 
  within 
  which 
  lie 
  the 
  

   terete, 
  somewhat 
  curved 
  and 
  capitate 
  hairy 
  claspers 
  ; 
  the 
  part 
  of 
  ninth 
  

   sternite 
  visible 
  from 
  above 
  is 
  longer 
  than 
  sixth 
  tergite 
  without 
  its 
  

   median 
  process 
  ; 
  the 
  latter 
  is 
  ligulate, 
  rounded 
  apically 
  and 
  its 
  length 
  

   compared 
  to 
  the 
  tergite 
  is 
  as

  It

  of
