  The 
  posterior 
  angles 
  of 
  the 
  thorax 
  are 
  finely 
  carinated, 
  and 
  moderately 
  produced. 
  In 
  

   form 
  and 
  structure 
  approaches 
  very 
  near 
  to 
  Limonius, 
  but 
  is 
  easily 
  known 
  by 
  the 
  last 
  

   joint 
  of 
  the 
  antennae 
  being 
  considerably 
  larger 
  than 
  the 
  others, 
  and 
  by 
  the 
  first 
  joint 
  of 
  

   the 
  tarsi 
  being 
  longer 
  than 
  the 
  second.

  which 
  is, 
  however, 
  unknown 
  to 
  me; 
  Dejean, 
  in 
  

   his 
  catalogue, 
  places 
  it 
  in 
  Limonius; 
  it 
  seems 
  to 
  differ 
  from 
  the 
  one 
  here 
  described 
  by 
  

   the 
  feet 
  and 
  antennce 
  being 
  fusco-testaceous. 
  

  

  The 
  generic 
  name 
  is 
  derived 
  from 
  yafi(3%os, 
  socer.

  A 
  very 
  extensive, 
  but 
  apparently 
  natural 
  genus, 
  which 
  may 
  be 
  easily 
  divided 
  into 
  

   groups, 
  for 
  the 
  purpose 
  of 
  facilitating 
  the 
  determination 
  of 
  the 
  species. 
  Some 
  of 
  these 
  

   groups 
  have 
  received 
  generic 
  names, 
  and, 
  on 
  a 
  first 
  glance, 
  there 
  appear 
  to 
  be 
  certain 
  

   peculiarities 
  of 
  habit, 
  which 
  render 
  them 
  easy 
  to 
  be 
  recognised. 
  With 
  a 
  large 
  series 
  of 
  

   species, 
  these 
  differences 
  appear 
  to 
  merge 
  insensibly 
  together, 
  so 
  that 
  no 
  well 
  defined 
  dis- 
  

   tinctions 
  remain. 
  For 
  this 
  reason, 
  I 
  consider 
  the 
  genera 
  Diacanthus 
  and 
  Pristilophus 
  as 
  

   untenable: 
  the 
  latter, 
  as 
  founded 
  by 
  Latreille, 
  is 
  perfectly 
  unintelligible, 
  and 
  as 
  reformed 
  

   by 
  Gcrmar, 
  contains 
  two 
  very 
  distinct 
  forms, 
  of 
  which 
  his 
  first 
  division 
  (forming 
  the 
  genus
