  either 
  side 
  in 
  a 
  blunt 
  tooth, 
  the 
  teeth 
  forming 
  with 
  the 
  

   apical 
  point 
  a 
  triangle. 
  Eyes 
  almost 
  parallel. 
  Ocelli 
  not 
  

   forming 
  a 
  triangle, 
  the 
  hinder 
  separated 
  from 
  the 
  eyes 
  

   by 
  the 
  length 
  of 
  the 
  second 
  and 
  third 
  antennal 
  joints 
  united 
  ;, 
  

   and 
  from 
  each 
  other 
  by 
  not 
  very 
  much 
  more 
  than 
  the 
  

   length 
  of 
  the 
  second 
  joint. 
  The 
  third 
  antennal 
  joint 
  is 
  

   fully 
  one 
  half 
  longer 
  than 
  the 
  fourth, 
  and 
  not 
  much 
  shorter 
  

   than 
  the 
  first. 
  There 
  is 
  a 
  short 
  blunt 
  triangular 
  tooth 
  on 
  

   the 
  hinder 
  edge 
  of 
  the 
  mesosternum. 
  The 
  punctuation 
  of 
  

   the 
  head 
  is 
  moderate 
  ; 
  on 
  the 
  thorax 
  much 
  coarser 
  and 
  

   rugose 
  ; 
  the 
  metanotum 
  is 
  rugose 
  ; 
  the 
  triangular 
  area 
  on 
  

   the 
  median 
  segment 
  is 
  large, 
  transversely 
  striated, 
  and 
  

   indistinctly 
  furrowed 
  down 
  the 
  middle. 
  The 
  pygidial 
  area 
  

   is 
  opaque, 
  irregularly 
  punctured 
  ; 
  twice 
  broader 
  at 
  the 
  

   base 
  than 
  at 
  the 
  apex, 
  the 
  contraction 
  taking 
  place 
  beyond 
  

   the 
  middle 
  ; 
  the 
  apex 
  rounded, 
  the 
  sides 
  punctured, 
  the 
  

   hair 
  fringe 
  long, 
  dense, 
  and 
  fulvous. 
  Hypopygium 
  finely 
  

   punctured, 
  opaque 
  ; 
  the 
  incision 
  triangular, 
  reaching 
  a 
  very 
  

   little 
  beyond 
  the 
  middle. 
  

  

  In 
  the 
  $ 
  the 
  clypeus 
  is 
  equally 
  convex, 
  bluntly 
  keeled 
  in 
  

   the 
  middle, 
  the 
  apex 
  broadly 
  rounded 
  ; 
  the 
  triangular 
  area 
  

   on 
  the 
  median 
  segment 
  is 
  longitudinally 
  striolate, 
  the 
  striae 
  

   wide 
  apart 
  ; 
  the 
  pygidial 
  area 
  is 
  of 
  equal 
  width 
  and 
  is 
  

   punctured 
  irregularly. 
  

  

  In 
  both 
  sexes 
  the 
  petiole 
  is 
  wider 
  than 
  long, 
  sparsely 
  

   punctured 
  ; 
  the 
  sculpture 
  on 
  the 
  other 
  segments 
  is 
  weak 
  

   and 
  becomes 
  almost 
  obsolete 
  on 
  the 
  fifth 
  segment.
