  Elytra 
  rather 
  more

  widely 
  rounded,

  with 
  

   some 
  large

  long

  As 
  this 
  is 
  the 
  only 
  known 
  species 
  of 
  the 
  genus, 
  I 
  cannot 
  

   compare 
  it 
  with 
  any 
  other, 
  but 
  I 
  may 
  say 
  that 
  superficially 
  

   there 
  is 
  a 
  strong 
  likeness 
  between 
  it 
  and 
  Bates' 
  Pirantillus 
  

   feae 
  (Ann. 
  Mus. 
  Civ. 
  Gen. 
  1889, 
  109).

  Figured

   Macleay's 
  specimen, 
  the 
  type 
  of 
  a 
  vast 
  genus, 
  is 
  the 
  only 
  

   example 
  of 
  the 
  species 
  I 
  have 
  seen. 
  Macleay 
  was 
  quite 
  

   right 
  in 
  associating 
  his 
  new 
  genus 
  with 
  Sphodrus 
  and 
  

   Anchomenus. 
  In 
  his 
  Monograph 
  of 
  the 
  genus 
  Colpodes 
  

   (Ann. 
  Soc. 
  Ent. 
  Fr. 
  1859, 
  359) 
  Chaudoir 
  just 
  mentions 
  the 
  

   genotype, 
  but 
  in 
  his 
  subsequent 
  and 
  much 
  more 
  extended 
  

   " 
  Eevision 
  " 
  (Ann. 
  Soc. 
  Ent. 
  Fr. 
  1878) 
  he 
  ignores 
  it 
  alto- 
  

   gether. 
  Mr. 
  Alluaud 
  (Ann. 
  Soc. 
  Ent. 
  Fr. 
  1916, 
  78) 
  has 
  

   recently 
  drawn 
  attention 
  to 
  Chaudoir's 
  Observations 
  on 
  

   the 
  genus 
  (Mon. 
  292), 
  which 
  I 
  think 
  worth 
  quoting, 
  as 
  an 
  

   amusing 
  instance 
  of 
  his 
  methods 
  :
