  The 
  metathorafiic 
  episterna 
  are 
  nearly 
  as 
  in 
  C. 
  mcestus 
  

   (Dej.), 
  shorter 
  and 
  broader 
  than 
  in 
  C. 
  transfuga 
  (Chaud.), 
  

   and 
  are 
  shorter 
  than 
  the 
  width 
  at 
  the 
  base. 
  The 
  upper 
  

   surface 
  is 
  very 
  dark 
  brown, 
  glossy, 
  and 
  with 
  a 
  brassy 
  

   tinge, 
  the 
  under 
  side 
  with 
  the 
  elytral 
  epipleurse 
  being 
  

   lighter, 
  almost 
  tawny 
  brown. 
  The 
  facies 
  is 
  that 
  of 
  

   certain 
  species 
  of 
  Platjjsnvi. 
  The 
  posterior 
  thoracic 
  seta 
  

   is 
  apparently 
  absent.

  good 
  series 
  of 
  examples. 
  

  

  Although 
  superficially 
  so 
  similar 
  to 
  C. 
  steropoides, 
  this 
  

   species, 
  as 
  will 
  be 
  remarked 
  on 
  comparison 
  of 
  the 
  de- 
  

   scriptions, 
  differs 
  in 
  numerous 
  points 
  of 
  structure 
  of 
  high 
  

   importance. 
  The 
  posterior 
  tactile 
  seta 
  of 
  the 
  thorax 
  is 
  

   implanted 
  on 
  the 
  thickened 
  edge 
  very 
  near 
  the 
  hind 
  

   angle, 
  in 
  which 
  it 
  produces 
  a 
  slight 
  notch, 
  as 
  in 
  many 
  

   other 
  species 
  of 
  Colpodes.
