  Phucobius. 
  

  

  This 
  genus 
  has, 
  by 
  an 
  error 
  of 
  observation 
  of 
  M. 
  Fauvel, 
  

   been 
  merged 
  in 
  Cafius. 
  The 
  ligula 
  is, 
  however, 
  of 
  a 
  different 
  

   type 
  from 
  that 
  obtaining 
  in 
  Philonthus 
  and 
  Cajius, 
  and 
  the 
  

   general 
  structure 
  brings 
  the 
  insect 
  nearer 
  to 
  Ocypus; 
  the 
  

   ligula, 
  though 
  not 
  large, 
  is 
  not 
  at 
  all 
  acuminate 
  at 
  the 
  apex, 
  

   and 
  its 
  two 
  lobes 
  are 
  evidently 
  separated 
  though 
  not 
  deeply 
  

   divided. 
  This 
  statement 
  is 
  based 
  on 
  the 
  observation 
  of 
  

   several 
  examples 
  at 
  different 
  times 
  and 
  of 
  a 
  preparation 
  of 
  

   the 
  part 
  mounted 
  in 
  Canada 
  balsam. 
  Dr. 
  Horn 
  is 
  more 
  

   correct 
  in 
  supposing 
  that 
  Philonthus 
  canescens, 
  Mann., 
  may 
  

   be 
  a 
  Phucobius; 
  I 
  find, 
  however, 
  although 
  there 
  is 
  a 
  con- 
  

   siderable 
  analogy 
  between 
  the 
  two 
  insects 
  in 
  many 
  respects, 
  

   yet 
  they 
  are 
  far 
  from 
  agreeing 
  in 
  their 
  structure. 
  In 
  the 
  

   North-American 
  insect 
  the 
  division 
  between 
  the 
  lobes 
  of 
  the 
  

   ligula 
  is 
  only 
  indistinct, 
  the 
  palpi, 
  mandibles, 
  antennae, 
  and
