  broadly 
  and

  the 
  middle 
  of 
  the 
  apical 
  part 
  broadly 
  raised 
  ; 
  

   the 
  base 
  irregularly 
  reticulated 
  with 
  two 
  longitudinal 
  keels 
  

   in 
  the 
  middle 
  ; 
  the 
  apical 
  part 
  has 
  a 
  central 
  and 
  lateral 
  keels, 
  

   which 
  enclose 
  two 
  wide

  base 
  very 
  smooth

   triangular 
  ; 
  on 
  either 
  side 
  of

  is 
  a 
  stronger 
  keel, 
  

   which 
  does 
  not 
  quite 
  reach 
  to 
  the 
  apex, 
  which, 
  at 
  the 
  

   sides, 
  is 
  much 
  more 
  closely 
  and 
  finely 
  punctured. 
  The

   striated 
  ; 
  the 
  middle 
  of 
  the 
  segment 
  to 
  near 
  the 
  apex 
  

   strongly 
  longitudinally 
  striolated 
  ; 
  the 
  oblique 
  furrows 
  

   marked 
  with 
  rather 
  widely 
  separated, 
  and 
  not 
  very 
  

   distinct 
  keels; 
  on 
  the 
  side 
  of 
  the 
  triangular 
  basal 
  space 
  

   enclosed 
  by 
  them 
  is 
  an 
  indistinct 
  longitudinal 
  furrow.
