  Rostrum 
  short 
  and 
  incrassated, 
  very 
  deep 
  at 
  the 
  apex, 
  with 
  two 
  

   longitudinal 
  crests 
  above, 
  which 
  are 
  distinctly 
  punctured, 
  and 
  

   separated 
  by 
  a 
  deep 
  groove 
  ; 
  the 
  apex 
  with 
  a 
  triangular 
  plate, 
  

   deeply 
  indented 
  in 
  the 
  middle, 
  and 
  with 
  apex 
  joining 
  a 
  short 
  

   middle 
  ridge 
  behind. 
  Head 
  very 
  finely 
  rugose 
  ; 
  forehead 
  with 
  

   two 
  deep 
  depressions, 
  separated 
  by 
  a 
  small 
  narrow 
  ridge. 
  Thorax 
  

   broader 
  than 
  long, 
  with 
  a 
  transverse 
  indentation 
  near 
  the 
  apex 
  ; 
  

   the 
  sides 
  produced 
  in 
  the 
  middle 
  into 
  a 
  horizontally 
  compressed 
  

   process, 
  which 
  is 
  truncated 
  externally, 
  rounded 
  in 
  front, 
  and 
  emar- 
  

   ginated, 
  and 
  presents 
  an 
  acute 
  angle 
  posteriorly 
  ; 
  the 
  dorsal 
  sur- 
  

   face 
  witli 
  two 
  longitudinal 
  crests, 
  which 
  diverge 
  somewhat 
  in 
  the 
  

   middle 
  (where 
  they 
  are 
  much 
  elevated) 
  and 
  are 
  indented 
  near 
  the 
  

   fore 
  part, 
  and 
  have 
  two 
  or 
  three 
  transverse 
  indentions 
  on 
  the 
  

   hinder 
  part 
  ; 
  the 
  summits 
  of 
  these 
  crests 
  (as 
  well 
  as 
  those 
  on 
  the 
  

   rostrum) 
  are 
  distinctly 
  punctured 
  ; 
  the 
  surface, 
  on 
  either 
  side 
  and 
  

   between 
  them, 
  presents 
  a 
  few 
  rugae, 
  but 
  is 
  impunctate. 
  Elytra 
  

   oblong, 
  about 
  equal 
  in 
  width 
  to 
  the 
  thorax, 
  the 
  sides 
  nearly 
  

   straight, 
  parallel, 
  and 
  perpendicular, 
  and 
  the 
  apical 
  portion 
  much 
  

   bent 
  down 
  ; 
  dorsal 
  surface 
  of 
  each 
  elytron 
  with 
  two 
  rows 
  of 
  

   tubercles, 
  of 
  which 
  the 
  outer 
  row 
  is 
  the 
  longer 
  ; 
  the 
  foremost 
  

   tubercle 
  of 
  this 
  series 
  is 
  very 
  large, 
  and 
  somewhat 
  compressed
