  Scutellum

  Hemelytra 
  uniformly 
  brownish, 
  yellowing 
  medially 
  and 
  in 
  em- 
  

   bolar 
  region; 
  shagreened 
  as

  scutellum. 
  Embolium 
  about 
  normal 
  

   for 
  the 
  genus, 
  length-to- 
  width 
  ratio 
  29:9 
  (31 
  percent), 
  rarely 
  with 
  

   some 
  sparse, 
  occasional 
  marginal 
  pilosity. 
  Hemelytra 
  moderately 
  

   exposing 
  lateral 
  connexival 
  edges, 
  which 
  latter 
  have 
  some 
  prominent, 
  

   short 
  yellow 
  pilosity. 
  Hemelytra 
  just 
  attaining 
  abdominal 
  apex. 
  

  

  Venter 
  reddish 
  brown, 
  contrasting 
  with 
  the 
  light-colored 
  legs. 
  

   Connexival 
  posterolateral 
  angles 
  weakly 
  acute-angulate, 
  gradually 
  

   enlarging 
  posteriorly, 
  not 
  in 
  the

  its 
  deepest 
  

   point. 
  Male 
  genital 
  process 
  sharply 
  right-angulate, 
  tapering 
  to
