  : 
  Black, 
  shining, 
  elytra 
  and 
  scutellum 
  clothed 
  with 
  dense, 
  

   contiguous, 
  ovate 
  yellow 
  scales, 
  prothorax 
  with 
  a 
  narrow 
  but 
  very 
  

   distinct 
  basal 
  band 
  of 
  similar 
  scales, 
  edge 
  of 
  propygidium, 
  pygidium, 
  

   and

  head 
  rugose, 
  hardly 
  pubescent, 
  clypeus 
  slightly 
  

   narrowed 
  laterally, 
  slightly 
  bi-dentate 
  in 
  the 
  centre 
  at 
  the 
  apex 
  and 
  

   with 
  the 
  outer 
  angles 
  strongly 
  reflexed 
  ; 
  prothorax 
  nearly 
  glabrous 
  

   except 
  for 
  the 
  narrow 
  basal 
  line 
  of 
  yellow 
  scales 
  which, 
  in 
  well- 
  

   preserved 
  examples, 
  is 
  continued 
  on 
  the 
  outer 
  margins, 
  it 
  is 
  closely 
  

   scabroso-punctate 
  in 
  the 
  anterior 
  part, 
  but 
  simply 
  punctate 
  towards 
  

   the 
  basal 
  part, 
  and 
  the 
  longitudinal 
  median 
  furrow 
  is 
  very 
  deep 
  ; 
  

   elytra 
  not 
  costulate, 
  and 
  entirely 
  covered

  the 
  scales 
  which 
  are 
  

   comparatively 
  large 
  ; 
  basal 
  tooth 
  of 
  anterior 
  tibiae 
  broad 
  and 
  trian- 
  

   gular, 
  but 
  not 
  as 
  long 
  as 
  the 
  one 
  preceding 
  it 
  ; 
  hind 
  tibiae 
  as 
  in 
  the 
  

   other 
  species. 
  

  

  Female 
  : 
  Like 
  the 
  male 
  ; 
  the 
  scales 
  are 
  similar 
  and 
  equally 
  dense 
  ; 
  

   the 
  pygidium 
  is 
  more 
  convex 
  and 
  this 
  character 
  is 
  the 
  only 
  one 
  that 
  

   denotes 
  the 
  sex.
