  This 
  genus 
  should 
  be 
  placed 
  near 
  Trochoderus 
  and 
  Stilicus. 
  

   It 
  differs 
  from 
  the 
  latter 
  by 
  the 
  structure 
  of 
  the 
  labrum 
  and 
  

   mandibles 
  and 
  the 
  much 
  greater 
  development 
  of 
  the 
  terminal 
  

   joint 
  of 
  the 
  maxillary 
  palpi, 
  as 
  well 
  as 
  by 
  the 
  less 
  elongation 
  

   of 
  the 
  first 
  joint 
  of 
  the 
  hind 
  foot. 
  The 
  prosternum 
  is 
  without 
  

   the 
  concavity 
  visible 
  in 
  all 
  the 
  Stilici, 
  and 
  the 
  antennas 
  are 
  

   more 
  of 
  the 
  filiform 
  type. 
  The 
  genus 
  in 
  fact 
  seems 
  to 
  

   be 
  more 
  closely 
  connected 
  with 
  several 
  genera 
  that 
  form 
  

   a 
  series 
  of 
  connecting-links 
  between 
  Medon 
  and 
  Stilicus. 
  

   From 
  Trochoderus, 
  the 
  genus 
  of 
  the 
  group 
  in 
  question 
  to 
  

   which 
  it 
  is 
  nearest, 
  it 
  departs 
  by 
  the 
  very 
  different 
  structure 
  

   of 
  the 
  labrum 
  ; 
  this 
  has 
  two 
  teeth 
  in 
  the 
  middle, 
  but 
  it 
  has 
  

   also 
  a 
  longitudinal 
  carina 
  extending 
  all 
  along 
  the 
  upper 
  sur- 
  

   face 
  of 
  the 
  labrum 
  and 
  projecting 
  in 
  front, 
  so 
  that 
  the 
  middle 
  

   of 
  the 
  labrum 
  is 
  actually 
  tridenticulate. 
  The 
  comparative 
  

   proportions 
  of 
  the 
  joints 
  of 
  the 
  hind 
  foot 
  constitute 
  another 
  

   difference 
  between 
  the 
  two 
  genera.
