  differs 
  in 
  the 
  following 
  points 
  : 
  

   the 
  margin 
  of 
  the 
  head

  two 
  small 
  median 
  tubercles, 
  the 
  prothorax

  its 
  pubescence 
  consists 
  of 
  broad, 
  short 
  

   reddish-yellow, 
  scale-like 
  hairs 
  ; 
  the 
  smooth 
  costae 
  of 
  the 
  elytra 
  bear 
  

   stiff 
  black 
  bristles 
  ; 
  the 
  pygidium 
  is 
  reddish 
  yellow 
  with 
  two 
  black 
  

   spots 
  at 
  the 
  base

  a

   tooth 
  at

  knee-joint, 
  and 
  several 
  smaller 
  teeth 
  below 
  this 
  on 
  the 
  

   inner 
  edge

  the
