  sparsely 
  covered 
  with 
  large 
  punctures 
  so 
  placed 
  as 
  leave 
  a 
  large 
  smooth 
  space 
  each 
  

   side 
  of 
  the 
  middle. 
  Elytra 
  gradually 
  widened 
  behind, 
  rugose 
  and 
  punctured, 
  with 
  

   the 
  usual 
  faint 
  costte, 
  and 
  a 
  strongly 
  marked 
  submarginal 
  one, 
  extending 
  nearly 
  to 
  

   the 
  base. 
  Propygidium 
  sparsely, 
  towards 
  the 
  tip 
  strongly 
  punctured 
  ; 
  pygidium 
  

   strongly 
  punctured; 
  abdomen 
  punctured, 
  more 
  faintly 
  in 
  the 
  middle; 
  pectus 
  clothed 
  

   with 
  moderately 
  long 
  yellow 
  hair. 
  

  

  The 
  male 
  has 
  the 
  club 
  of 
  the 
  antennce 
  longer 
  than 
  the 
  stem 
  ; 
  the 
  abdomen 
  flattened 
  

   in 
  the 
  middle 
  ; 
  the 
  penultimate 
  segment 
  with 
  a 
  semicircular 
  curved 
  elevation, 
  and 
  

   middle 
  fovea, 
  and 
  the 
  last 
  segment 
  with 
  a 
  longitudinal 
  broad 
  furrow. 
  The 
  abdomen 
  

   of 
  the 
  female 
  is 
  almost 
  uniformly 
  punctured, 
  the 
  punctures 
  of 
  the 
  last 
  two 
  segments 
  

   being 
  stronger 
  ; 
  the 
  pygidium 
  is 
  triangular, 
  and 
  slightly 
  conical 
  at 
  tip, 
  while 
  in 
  the 
  

   male 
  it 
  is 
  broader 
  and 
  convex. 
  

  

  This 
  species 
  is 
  remarkable 
  for 
  the 
  length 
  of 
  the 
  submarginal 
  elytral 
  costa, 
  which 
  

   in 
  most 
  species 
  is 
  seen 
  only 
  near 
  the 
  apex.
