  General 
  appearance 
  of 
  the 
  preceding 
  species, 
  but 
  a 
  little 
  narrower, 
  

   and 
  with 
  the 
  elytra 
  more 
  finely 
  punctured 
  and 
  the 
  striae 
  nearly 
  

   invisible 
  ; 
  head 
  as 
  in 
  B. 
  trituberculatus 
  ; 
  the 
  mandibles 
  are 
  sharply 
  

   aculeate 
  in 
  the 
  outer 
  angle 
  of 
  the 
  anterior 
  margin 
  and 
  very 
  sharply 
  

   dentate 
  in 
  the 
  inner, 
  the 
  spine-like 
  tooth 
  being 
  recurved 
  ; 
  the 
  

   cephalic 
  horn 
  is 
  sharper 
  and 
  longer 
  ; 
  in 
  the 
  male 
  the 
  prothorax 
  

   is 
  similarly 
  sculptured, 
  but 
  is 
  a 
  little 
  more 
  ampliate 
  laterally 
  at 
  

   middle, 
  and 
  it 
  is 
  deeply 
  and 
  broadly 
  excavated 
  from 
  the 
  anterior 
  

   margin 
  to 
  two-thirds 
  of 
  the 
  length, 
  with 
  the 
  anterior 
  part 
  of 
  the 
  

   walls 
  of 
  the 
  excavation 
  produced 
  into 
  two 
  conical, 
  very 
  conspicuous 
  

   tubercles 
  ; 
  the 
  posterior 
  part 
  of 
  the 
  disk 
  is 
  slightly 
  impressed 
  in 
  the 
  

   middle 
  ; 
  the 
  female 
  much 
  resembles 
  that 
  of 
  B. 
  trituberculatus, 
  but 
  

   the 
  prothorax 
  is 
  much 
  more 
  deeply 
  and 
  broadly 
  punctured 
  and 
  is 
  

   even 
  scrobiculate 
  laterally, 
  and 
  there 
  is 
  a 
  distinct 
  impression, 
  callose 
  

   on 
  each 
  side, 
  in 
  the 
  anterior 
  part 
  of 
  the 
  prothorax 
  ; 
  under 
  side 
  as 
  in 
  

   B. 
  trituberculatus, 
  but 
  the 
  four 
  outer 
  spines 
  on 
  the 
  intermediate 
  

   and 
  posterior 
  tibiae 
  are 
  not 
  connate 
  at 
  base.
