  This 
  species 
  has 
  some 
  resemblance 
  to 
  the 
  beautiful 
  C. 
  Cantori 
  

   of 
  Hope, 
  but 
  differs 
  in 
  many 
  respects, 
  particularly 
  in 
  the 
  colour 
  

   of 
  the 
  thorax 
  and 
  antennae. 
  It 
  also 
  nearly 
  approaches 
  the 
  

   C. 
  Bungii, 
  Fald., 
  particularly 
  the 
  variety 
  called 
  cyanicornis 
  of 
  

   Dupt.
