  One 
  male

  Mr.

  This 
  species 
  has 
  nearly 
  the 
  form, 
  sculpture 
  

   and 
  sexual 
  characters 
  of 
  the 
  preceding, 
  but 
  there 
  are 
  no 
  hairs 
  on 
  the 
  upper 
  surface 
  

   except 
  between 
  the 
  eyes. 
  From 
  the 
  next 
  species 
  it 
  differs 
  by 
  its 
  more 
  cylindrical 
  

   form, 
  more 
  sparsely 
  punctured 
  thorax, 
  and 
  by 
  the 
  more 
  strongly 
  margined 
  and 
  less 
  

   emarginate 
  clypeus.
