  This 
  genus 
  is 
  an 
  example 
  in 
  the 
  Staphylinidse 
  of 
  the 
  

   reproduction 
  of 
  some 
  of 
  the 
  characters 
  of 
  species 
  with 
  tarsi 
  

   like 
  Phytophaga, 
  and 
  we 
  may 
  assume 
  that 
  its 
  habits 
  are 
  

   arboreal.

  punctate, 
  the

  in 
  front 
  very 
  

   dense, 
  on

  middle, 
  the 
  inflexed 
  sides 
  also 
  tawny,

  femora

  the

   colour. 
  

  

  I 
  am 
  not 
  able 
  to 
  point 
  out 
  any 
  sexual 
  characters 
  ; 
  in 
  one 
  

   of 
  the 
  specimens 
  there 
  are 
  two, 
  in 
  the 
  other 
  two 
  specimens 
  

   three, 
  joints 
  of 
  the 
  antennas 
  dark, 
  and 
  there 
  is 
  also 
  an 
  appa- 
  

   rently 
  variable 
  transverse 
  impression 
  on 
  the 
  middle 
  of 
  the 
  

   head
