  small, 
  convex

  Thorax 
  a

  A 
  small 
  series 
  of 
  this 
  species 
  was 
  found 
  amongst 
  moss 
  at 
  

   Ashinoyu, 
  and 
  two 
  or 
  three 
  examples 
  were 
  captured 
  at 
  

   Miyanoshita. 
  Pcederus 
  Poioeri 
  and 
  parallelus 
  were 
  associated 
  

   with 
  it.

  This 
  is 
  readily 
  distinguished 
  from 
  the 
  other 
  Japanese 
  

   species 
  by 
  the 
  canaliculate 
  prothorax 
  and 
  the 
  longer 
  elytra. 
  

   The 
  head 
  is 
  rather 
  narrow, 
  not 
  at 
  all 
  transverse 
  ; 
  the 
  thorax 
  

   elongate, 
  longer 
  than 
  broad, 
  the 
  lateral 
  angles 
  quite 
  indistinct, 
  

   the 
  median 
  channel 
  is 
  fine 
  and 
  shining, 
  thus 
  contrasting 
  with 
  

   the 
  rest 
  of 
  the 
  thorax. 
  The 
  elytra 
  are 
  narrow, 
  somewhat 
  

   shining, 
  excessively 
  finely 
  punctate, 
  with 
  a 
  few 
  indistinct 
  

   larger 
  punctures 
  ; 
  they 
  are 
  of 
  a 
  fuscescent-red 
  colour, 
  darker 
  

   towards 
  the 
  suture.
