   ish 
  anuulus 
  and 
  the

  fuscescent 
  or 
  Havescent, 
  the

  black 
  

   almost 
  or 
  quite 
  to 
  the

  twelve 
  to 
  thirteen, 
  rarely 
  eleven,

  Extremity 
  of 
  male 
  abdomen 
  feebly 
  clavate, 
  a 
  little 
  

   recurved, 
  the 
  snpraanal 
  plate 
  triangular 
  with 
  slightly 
  convex 
  sides 
  and 
  

   feebly 
  acutangulate 
  apex, 
  the 
  median 
  sulcus 
  rather 
  broad 
  and 
  equal, 
  

   reaching 
  only 
  the 
  middle 
  of 
  the 
  plate 
  and 
  there 
  fading 
  abruptly, 
  the 
  

   moderately 
  high 
  walls 
  terminating 
  against 
  a 
  feebly 
  transverse 
  plica; 
  

   furcula 
  consisting 
  of 
  a 
  pair 
  of 
  very 
  slender 
  and 
  brief 
  needles 
  overlying 
  

   the 
  submedian 
  ridges 
  of 
  the 
  supraanal 
  plate, 
  not 
  nearly 
  so 
  long 
  as 
  the 
  

   last 
  dorsal 
  segment 
  ; 
  cerci 
  compressed 
  substyliform, 
  moderately 
  broad 
  

   at 
  base, 
  tapering 
  more 
  rapidly 
  in 
  the 
  basal 
  than 
  in 
  the 
  apical 
  half, 
  

   bluntly 
  acuminate 
  at 
  tip 
  and 
  about 
  as 
  long 
  as 
  the 
  supraanal 
  i^late; 
  

   subgenital 
  plate 
  narrow 
  and 
  apically 
  narrowing 
  slightly, 
  the 
  lateral 
  

   and 
  apical 
  margins 
  in 
  about 
  the 
  same 
  plane, 
  the 
  apical 
  margin 
  laterally 
  

   compressed 
  mesially, 
  so 
  as 
  to 
  simulate 
  an 
  apical 
  tubercle, 
  entire.
