   A 
  large 
  series 
  of 
  examples. 
  

  

  In 
  C. 
  pterosticJioides 
  the 
  elytra 
  have 
  a 
  coppery 
  tinge, 
  

   and 
  are 
  much 
  more 
  finely 
  striated 
  ; 
  the 
  thorax, 
  though 
  

   essentially 
  similar 
  in 
  shape, 
  differs 
  conspicuously 
  in 
  

   being 
  less 
  narrowed 
  in 
  front 
  of 
  the 
  anterior 
  dilatation, 
  

   with 
  less 
  acute 
  angles, 
  so 
  that 
  it 
  is 
  as 
  broad 
  at 
  the 
  base 
  

   as 
  at 
  the 
  apex, 
  and 
  the 
  hind 
  tarsi 
  are 
  flattened 
  above, 
  

   and 
  hence 
  appear 
  broader.

  not 
  closely

  any 
  other 
  known

   in

   setse.
