  The 
  thorax 
  varies 
  in 
  outline, 
  examples 
  in 
  which 
  it 
  is 
  

   narrower 
  and 
  subcordate 
  are 
  purplish 
  violet, 
  at 
  least 
  on 
  

   the 
  disk 
  of 
  the 
  thorax, 
  and 
  so 
  far 
  resemble 
  C. 
  porpltyrius 
  

   in 
  form 
  and 
  colour; 
  but 
  they 
  are 
  distinguishable 
  from 
  

   that 
  species 
  by 
  the 
  black 
  3rd 
  antennal 
  joint 
  and 
  pitchy 
  

   black 
  legs.

  single 
  example 
  from
