  Not 
  very 
  similar 
  to 
  any 
  species

  This 
  is 
  closely 
  allied 
  to 
  B. 
  obtusus, 
  but 
  I 
  have 
  little 
  doubt 
  

   is 
  distinct, 
  as 
  it 
  is 
  broader, 
  and 
  remarkable 
  on 
  account 
  of 
  the 
  

   very 
  dense 
  coarse 
  punctuation 
  of 
  the 
  thorax. 
  The 
  male 
  has 
  

   characters 
  similar 
  to 
  those 
  of 
  B.
