  Head 
  triangular 
  ; 
  clypeus 
  scarcely 
  broader 
  than 
  long, 
  its 
  surface 
  

   transversely 
  convex; 
  antennae 
  slender, 
  filiform, 
  the 
  second 
  joint 
  

   short, 
  cylindrical, 
  the 
  third 
  nearly 
  twice

  joint 
  more

  Thorax 
  nearly 
  twice 
  as

   at 
  the 
  base 
  ; 
  sides 
  rather 
  broadly 
  margined, 
  slightly 
  converging 
  

   and 
  slightly 
  sinuate 
  from 
  the 
  base 
  to 
  the 
  middle, 
  thence 
  more 
  

   quickly 
  converging 
  towards 
  the 
  apex, 
  the 
  anterior 
  angles 
  slightly 
  

   produced, 
  subacute; 
  disk 
  transversely 
  convex, 
  very 
  remotely 
  punc- 
  

   tured, 
  hinder 
  disk 
  impressed 
  on 
  either 
  side 
  with 
  a 
  large, 
  shallow, 
  

   ill-defined 
  fovea. 
  Elytra 
  broadly 
  subquadrate-ovate, 
  slightly 
  dilated 
  

   posteriorly, 
  their 
  apices 
  obtusely 
  rounded 
  ; 
  above 
  moderately 
  con- 
  

   vex, 
  transversely 
  depressed 
  below 
  the 
  basilar 
  space, 
  the 
  latter 
  

   slightly 
  thickened 
  ; 
  finely 
  but 
  not 
  very

  is 
  a 
  short, 
  broad,

   ill-defined 
  transverse 
  sulcation 
  ; 
  running

  from 
  the
