  wedge-shaped 
  ; 
  antennse 
  fili- 
  

   form, 
  nearly 
  as 
  long 
  as 
  the

  the 
  relative 
  length 
  of 
  the 
  joints 
  

   as 
  in 
  D.

  the 
  four 
  outer

  piceous. 
  Thorax

   upper 
  surface 
  convex, 
  minutely 
  punctured

   sulcation, 
  the 
  surface 
  of

  This 
  species 
  is 
  very 
  closely 
  allied 
  to 
  the 
  following 
  one, 
  

   but 
  may 
  be 
  separated 
  by 
  the 
  different 
  coloration 
  of 
  the 
  

   upper 
  surface 
  of 
  the 
  body 
  and 
  antennse, 
  and 
  by 
  the 
  

   transversely 
  sulcate 
  thorax.
