  blackish 
  fuscous

  It 
  is 
  also 
  reported

  This 
  species 
  is 
  very 
  closely 
  allied 
  to 
  the 
  last, 
  differing 
  from 
  it 
  in 
  its 
  

   narrower 
  interspace 
  between 
  the 
  sternal 
  lobes, 
  the 
  oblique 
  bauds 
  on 
  

   the 
  outer 
  face 
  of 
  the 
  hind 
  femora, 
  the 
  more 
  distant 
  forks 
  of 
  the 
  furcula 
  

   of 
  the 
  male, 
  and 
  the 
  stouter 
  apical 
  jjrocess 
  of 
  the 
  subgeuital 
  plate; 
  

   the 
  cerci 
  are 
  much 
  the 
  same.
