  This 
  genus, 
  apart 
  from 
  the 
  structure 
  of 
  the 
  side-piece 
  of 
  

   the 
  prothorax, 
  might 
  be 
  looked 
  on 
  as 
  a 
  close 
  ally 
  of 
  Ocypus 
  ; 
  

   but 
  as 
  this 
  part 
  is 
  developed 
  somewhat 
  as 
  in 
  the 
  Xanthopygini, 
  

   it 
  is 
  of 
  considerable 
  interest. 
  The 
  side-piece 
  is 
  large, 
  much 
  

   inflexed 
  at 
  the 
  base, 
  and 
  both 
  its 
  limiting 
  lines 
  run 
  forward 
  

   as 
  far 
  as 
  the 
  front 
  angles 
  of 
  the 
  thorax, 
  where, 
  though 
  much 
  

   approximated, 
  they 
  are 
  still 
  quite 
  separate 
  and, 
  the 
  upper 
  or 
  

   outer 
  one 
  at 
  any 
  rate, 
  distinct, 
  then 
  being 
  turned 
  upwards 
  to 
  

   the 
  front 
  face 
  of 
  the 
  thorax, 
  the 
  lower 
  or 
  inner 
  line 
  at 
  once 
  

   disappears 
  by 
  being 
  carried 
  to 
  the 
  inside 
  of 
  the 
  thorax. 
  In 
  

   this 
  latter 
  respect 
  the 
  genus 
  differs 
  from 
  the 
  Xanthopygini, 
  

   where 
  the 
  inner 
  line 
  is 
  continued 
  upwards 
  to 
  form 
  the 
  front 
  

   margin 
  of 
  the 
  thorax, 
  the 
  outer 
  line 
  becoming 
  obsolete 
  at 
  the 
  

   prominent 
  anterior 
  angle. 
  In 
  the 
  normal 
  Ocypus-aMies 
  the 
  

   two 
  lines 
  become 
  so 
  closely 
  approximate 
  that 
  they 
  may 
  be 
  

   called 
  conjoined 
  at 
  the 
  side 
  of 
  the 
  presternum. 
  

  

  Agelosus 
  agrees 
  with 
  Amickrotus 
  and 
  Anisolinus 
  in 
  respect 
  

   of 
  this 
  character, 
  but 
  it 
  differs 
  from 
  both 
  by 
  numerous 
  points 
  

   of 
  importance, 
  such 
  as 
  the 
  bilobed 
  ligula, 
  the 
  structure 
  of 
  the 
  

   palpi, 
  and 
  the 
  mesosternum. 
  The 
  only 
  species 
  of 
  the 
  genus 
  is 
  

   Goerius 
  carinatus, 
  Sharp 
  (Trans, 
  Ent. 
  Soc. 
  Lond. 
  1874, 
  

  

  P- 
  32 
  ): 
  

  

  This 
  species 
  was 
  found 
  in 
  several 
  localities, 
  but 
  only 
  in 
  

   few 
  examples 
  ; 
  these, 
  however, 
  exhibit 
  much 
  variation 
  in 
  the 
  

   length 
  of 
  the 
  elytra 
  and 
  in 
  the 
  colour 
  of 
  these 
  parts 
  and 
  of 
  

   the 
  legs 
  and 
  antennae. 
  The 
  elytra 
  are 
  sometimes 
  nearly 
  as 
  

   long 
  as 
  the 
  thorax, 
  sometimes 
  much 
  shorter 
  than 
  it, 
  and 
  their 
  

   colour, 
  as 
  well 
  as 
  that 
  of 
  the 
  legs 
  and 
  femora, 
  being 
  appa- 
  

   rently 
  normally 
  red, 
  becomes 
  to 
  a 
  greater 
  or 
  less 
  extent 
  black. 
  

   There 
  appears, 
  however, 
  only 
  to 
  be 
  one 
  species 
  amongst 
  these 
  

   variations. 
  The 
  male 
  has 
  a 
  broad 
  shallow 
  excision 
  of 
  the 
  

   hind 
  margin 
  of 
  the 
  last 
  ventral 
  plate, 
  the 
  front 
  being 
  broadly 
  

   dilated 
  in 
  each 
  sex.
