   Rostrum 
  nearly 
  one 
  fourth 
  shorter 
  than 
  the 
  thorax, 
  which 
  

   latter 
  is 
  rather 
  longer 
  than 
  broad 
  ; 
  a 
  little 
  in 
  front 
  of 
  the 
  middle, 
  

   the 
  sides 
  of 
  the 
  thorax 
  are 
  rather 
  suddenly 
  cut 
  in, 
  and 
  from 
  that 
  

   part 
  to 
  the 
  front 
  they 
  are 
  straight 
  and 
  converging 
  towards 
  the 
  

   fore 
  part, 
  so 
  that 
  the 
  lobe, 
  which 
  projects 
  considerably 
  beyond 
  

   the 
  head, 
  is 
  very 
  narrow 
  in 
  front, 
  where 
  it 
  terminates 
  in 
  two 
  semi- 
  

   acute 
  points. 
  All 
  this 
  part 
  of 
  the 
  thorax 
  is 
  flat 
  above, 
  but 
  grooved 
  

   along 
  the 
  middle 
  ; 
  on 
  the 
  hinder 
  part 
  of 
  the 
  thorax 
  the 
  sides 
  are 
  

   rounded, 
  but 
  there 
  is 
  a 
  slight 
  notch 
  on 
  either 
  side 
  rather 
  behind 
  

   the 
  mesial 
  line; 
  the 
  dorsal 
  surface 
  is 
  convex, 
  rugose, 
  has 
  some 
  

   small 
  scattered 
  granules, 
  and 
  is 
  furrowed 
  along 
  the 
  middle; 
  in 
  the 
  

   centre 
  is 
  a 
  short 
  keel. 
  The 
  elytra 
  are 
  rather 
  less 
  than 
  double 
  the 
  

   length 
  of 
  the 
  thorax, 
  and 
  of 
  an 
  elongate 
  ovate 
  form, 
  terminating 
  

   posteriorly 
  in 
  two 
  conical 
  tubercles; 
  at 
  the 
  base 
  they 
  are 
  scarcely 
  

   wider 
  than 
  the 
  thorax 
  at 
  the 
  same 
  part 
  ; 
  they 
  are 
  moderately 
  con- 
  

   vex, 
  and 
  the 
  whole 
  dorsal 
  surface 
  is 
  very 
  uneven 
  : 
  besides 
  nu- 
  

   merous 
  little 
  granules 
  there 
  are 
  about 
  ten 
  tubercles 
  on 
  each 
  

   elytron, 
  these 
  varying 
  somewhat 
  in 
  size, 
  of 
  a 
  more 
  or 
  less 
  rounded 
  

   form, 
  and 
  rugose 
  at 
  the 
  summit. 
  They 
  are 
  thus 
  disposed 
  : 
  — 
  three 
  

   (considerably 
  separated 
  from 
  each 
  other) 
  in 
  the 
  position 
  of 
  the 
  

   second 
  interstice 
  of 
  the 
  striae 
  ; 
  one 
  in 
  the 
  third, 
  about 
  midway 
  

   between 
  the 
  base 
  and 
  apex 
  of 
  the 
  elytra, 
  three 
  in 
  the 
  fourth 
  ; 
  one
