  black 
  with

  elytra

  covered 
  with 
  slightly 
  

   elongate 
  fiavescent 
  scales 
  so 
  closely 
  set 
  that 
  the 
  colour 
  of 
  the 
  

   background 
  is 
  not 
  visible 
  ; 
  the 
  whole 
  pygidial

  from 
  which 
  species 
  it 
  would 
  be

  it 
  

   but 
  for 
  this 
  character
