  bark 
  of 
  beech 
  trees.

  an 
  old 
  tree 
  at

  a 
  single 
  specimen. 
  

  

  This 
  very 
  remarkable 
  Quedius 
  may 
  be 
  placed 
  near 
  Q.

   and 
  Q. 
  ochripennis, 
  though 
  not 
  at 
  all 
  closely 
  allied 
  to 
  them 
  ; 
  

   the 
  Japanese 
  species 
  of 
  this 
  genus 
  form 
  a 
  series 
  of 
  remarkably 
  

   distinct 
  forms.

  conspicuous

   at 
  the 
  extremity. 
  Legs 
  short, 
  tibise 
  stout, 
  very

  A 
  single 
  example 
  of 
  this 
  peculiar 
  Quedius 
  was 
  found 
  on 
  an 
  

   old 
  tree 
  at 
  Mitzusawa, 
  18th 
  October, 
  1880 
  ; 
  it 
  is 
  a 
  female. 
  

   The 
  species 
  may 
  be 
  placed 
  near 
  Q. 
  laticollis, 
  though 
  very 
  

   peculiar 
  on 
  account 
  of 
  the 
  seta3 
  of 
  its 
  antennse 
  and 
  legs.
