  little 
  paler.

  very 
  indistinctly 
  alutaceous, 
  thorax 
  and 
  

   elytra 
  not 
  at 
  all. 
  Head 
  sparsely 
  and 
  rather 
  coarsely 
  punctured 
  

   medially, 
  punctures 
  more 
  numerous 
  and 
  rugose 
  around 
  the 
  eyes, 
  

   vertex 
  smooth 
  ; 
  thorax 
  somewhat 
  coarsely 
  and 
  closely 
  punctured, 
  

   punctures 
  elongate; 
  a 
  rather 
  narrow 
  median 
  stripe 
  impunctate, 
  

   bounded 
  by 
  very 
  irregular 
  and 
  indistinct 
  series 
  of 
  punctures 
  on 
  

   either 
  side 
  ; 
  elytral 
  punctures 
  slightly 
  coarser 
  and 
  sparser 
  ; 
  abdomen 
  

   dorsally 
  somewhat 
  less 
  coarsely 
  and 
  rather 
  closely 
  punctured, 
  more 
  

   sparsely 
  medially, 
  but 
  without 
  a 
  definite 
  smooth 
  stripe; 
  punctures 
  

   beneath 
  slightly 
  more 
  coarse, 
  the 
  apical 
  segment 
  not 
  at 
  all 
  strigose. 
  

   Head 
  distinctly 
  narrower 
  than 
  the 
  thorax 
  at 
  apex; 
  clypeus 
  broadly 
  

   emarginate, 
  angles 
  slightly 
  prominent, 
  bidenticulate 
  ; 
  antennae 
  

   reaching 
  the 
  middle 
  of 
  the

  seven 
  to 
  eleven 
  distinctly 
  

   larger, 
  about 
  as 
  long 
  as 
  wide; 
  first 
  joint 
  as 
  long 
  as 
  the 
  next 
  three; 
  

   second

  third 
  slightly 
  elongate, 
  subequal 
  ; 
  third 
  more 
  slender. 
  

   Thorax

  wide 
  as 
  long, 
  wider

  the 
  elytra, 
  with 
  the

  very 
  

   slightly 
  convergent 
  to 
  behind 
  the 
  middle, 
  thence 
  rather 
  strongly 
  

   convergent 
  and 
  moderately 
  arcuate 
  to 
  the 
  posterior 
  angles 
  which 
  

   are 
  scarcely 
  distinct; 
  anterior 
  angles 
  rather 
  distinctly 
  prominent; 
  

   side 
  margins 
  fine 
  throughout; 
  base 
  margined, 
  apex 
  unmargined; 
  a 
  

   feeble 
  impression 
  before 
  the 
  posterior 
  angles. 
  Elytra

  long 
  as 
  the 
  

   thorax, 
  as 
  long 
  as 
  wide;

  scarcely 
  impressed.
