  Male 
  : 
  Black, 
  prothorax 
  clothed 
  with 
  a 
  dense 
  flavescent 
  or 
  

   whitish, 
  slightly 
  lanuginose 
  pubescence 
  ; 
  elytra 
  with 
  four 
  bands 
  of 
  

   appressed, 
  squamulose 
  hairs 
  of 
  the 
  same 
  colour, 
  pygidium 
  and 
  

   abdomen 
  clothed 
  with 
  similar 
  hairs, 
  pectus 
  and 
  legs 
  densely 
  hairy 
  ; 
  

   head 
  and 
  prothorax 
  scabrose, 
  the 
  clypeus 
  is 
  straight 
  laterally 
  and 
  

   also 
  at 
  apex 
  ; 
  the 
  outer 
  angles 
  are 
  very 
  distinct, 
  and 
  the 
  apical 
  

   margin 
  is 
  plainly 
  reflexed 
  ; 
  scutellum 
  hairy 
  ; 
  elytra 
  very 
  little 
  

   broader 
  than 
  the 
  prothorax 
  at 
  the 
  base 
  but 
  very 
  plainly 
  narrowed 
  

   laterally 
  from 
  the 
  shoulder 
  towards 
  the 
  apex, 
  they 
  are 
  very 
  closely 
  

   punctured 
  and 
  have 
  on 
  each 
  side 
  two 
  somewhat 
  distinct 
  costules, 
  

   and 
  three 
  intervals 
  filled 
  with 
  the 
  appressed, 
  squamose 
  hairs 
  

   in 
  addition 
  to 
  the 
  outer 
  marginal 
  band, 
  but 
  the 
  third 
  one 
  is 
  often 
  

   obliterated, 
  or 
  very 
  indistinct 
  ; 
  pygidium 
  large 
  and 
  very 
  slanting 
  

   forwards, 
  being 
  almost 
  sub-horizontal 
  ; 
  hind 
  legs 
  moderately 
  

   robust, 
  hind 
  tibiae 
  sub-mucronate 
  inwardly 
  at 
  apex 
  and 
  having 
  an 
  

   apical 
  spur, 
  anterior 
  tibiae 
  strongly 
  tri-dentate 
  with 
  the 
  two 
  basal 
  

   teeth 
  closely 
  set 
  but 
  not 
  connate, 
  and 
  the 
  basal 
  one 
  shorter, 
  but 
  

   broader 
  than 
  the 
  intermediate 
  ; 
  all 
  the 
  claws 
  are 
  double 
  and 
  un- 
  

   equal, 
  the 
  anterior 
  ones 
  are 
  both 
  cleft, 
  the 
  inner 
  one 
  of 
  the 
  anterior 
  

   being 
  short 
  and 
  very 
  massive 
  and 
  less 
  deeply 
  cleft 
  than 
  the 
  other, 
  

   in 
  the 
  intermediate 
  and 
  posterior 
  legs 
  the 
  weaker 
  claw 
  is 
  very 
  small 
  

   and 
  simple, 
  and 
  the 
  stronger, 
  and 
  somewhat 
  elongate 
  one, 
  is 
  deeply 
  

   cleft. 
  

  

  Female 
  : 
  I 
  have 
  not 
  seen 
  the 
  female, 
  but 
  Burmeister 
  says 
  that 
  she 
  

   is 
  smaller, 
  narrower, 
  and 
  darker 
  than 
  the 
  male 
  ; 
  the 
  fore 
  margin 
  of 
  the 
  

   clypeus 
  is 
  not 
  much 
  raised, 
  and 
  the 
  squamose 
  hairs 
  are 
  not 
  so 
  dense.
