  Although 
  bearing 
  much 
  resemblance 
  to 
  the 
  Austro-Ma- 
  

   layan 
  species 
  of 
  JJelonuc/tus, 
  this 
  is 
  a 
  true 
  Quedionuchus. 
  

   The 
  remarkable 
  armature 
  of 
  the 
  hind 
  legs 
  is 
  very 
  like 
  that 
  

   of 
  the 
  Central- 
  American 
  Q. 
  femoralis. 
  

  

  I 
  do 
  not 
  see 
  any 
  characters 
  to 
  distinguish

  male.

  has 
  the 
  appearance 
  of 
  a 
  small 
  Quedius 
  of 
  

   the 
  liaphirus

  no

  to 
  its

  Two 
  examples 
  have 
  been 
  met 
  with 
  at 
  Nikko, 
  one 
  in 
  June 
  

   1880 
  another 
  in 
  July 
  1881, 
  which 
  do 
  not 
  differ 
  apparently 
  by 
  

   any 
  good 
  character 
  from 
  European 
  examples, 
  although 
  they 
  

   do 
  not 
  agree 
  quite 
  satisfactorily 
  therewith 
  in 
  all 
  their 
  details 
  

   and 
  differ 
  a 
  little 
  from 
  one 
  another. 
  More 
  information 
  must 
  

   therefore 
  be 
  obtained 
  before 
  we 
  can 
  decide 
  positively 
  about 
  

   these 
  examples.

  Common 
  in 
  fungi 
  in 
  Japan. 
  The 
  specimens 
  differ 
  a 
  little 
  

   from 
  those 
  found 
  in 
  Europe, 
  the 
  thorax 
  being 
  more 
  oblong, 
  

   with 
  less 
  rounded 
  hind 
  angles.
