  Agrees 
  rather 
  better 
  with 
  Chaudoir's 
  description 
  of 
  

   his 
  C. 
  biovatus 
  than 
  the 
  typical 
  specimen 
  of 
  that 
  species 
  

   in 
  the 
  Salle 
  collection 
  does, 
  with 
  the 
  exception 
  that 
  in 
  our 
  

   species 
  the 
  thorax 
  is 
  strongly 
  narrowed 
  behind, 
  and 
  not 
  

   equally 
  narrowed 
  behind 
  and 
  before, 
  as 
  stated 
  by 
  the 
  

   describer. 
  In 
  facies 
  C. 
  steropoides 
  resembles 
  a 
  small 
  

   Steropus, 
  e. 
  g., 
  S. 
  Illigeri, 
  except 
  that 
  the 
  elytra 
  are 
  

   more 
  ovate. 
  In 
  the 
  singular 
  absence 
  of 
  the 
  anterior 
  

   supra-orbital 
  seta 
  it 
  agrees 
  with 
  C. 
  sphodroides, 
  but 
  in 
  

   facies 
  the 
  two 
  species 
  are 
  wholly 
  dissimilar.
