  latter, 
  which 
  are 
  simple 
  with 
  the 
  trochanters 
  not 
  projecting 
  into 
  a 
  

   spine, 
  but 
  are 
  bluntly 
  dentate 
  on 
  each 
  side 
  of 
  the 
  articulation 
  of 
  the 
  

   knee 
  ; 
  hind 
  tibiae 
  thick, 
  swollen 
  inwardly 
  and 
  outwardly, 
  slightly 
  

   angular 
  near 
  the 
  knee 
  with 
  the 
  lower 
  apical 
  part 
  very 
  sharply 
  

   angular, 
  and 
  the 
  upper 
  part 
  developed 
  into 
  a 
  long 
  spinose 
  mucro 
  ; 
  the 
  

   four 
  basal 
  joints 
  of 
  the 
  hind 
  tarsi 
  are 
  short 
  and 
  very 
  robust, 
  and 
  the 
  

   fifth 
  is 
  greatly 
  developed, 
  thick, 
  as 
  long 
  as 
  the 
  four 
  preceding 
  and 
  

   denticulate 
  underneath, 
  outer 
  claw 
  very 
  robust, 
  as 
  long 
  as 
  the 
  fourth 
  

   joint, 
  simple, 
  inner 
  claw 
  very 
  minute 
  ; 
  the 
  claws 
  of 
  the 
  two 
  first 
  pairs 
  

   of 
  legs 
  are 
  double 
  and 
  both 
  cleft. 
  

  

  Female 
  : 
  The 
  female 
  is 
  shaped 
  like 
  the 
  male, 
  except 
  that 
  the 
  

   pygidium 
  is 
  sub-horizontal 
  ; 
  the 
  anterior 
  tibiae 
  are, 
  however, 
  more 
  

   distinctly 
  tri-dentate 
  ; 
  the 
  discoidal 
  part 
  of 
  the 
  prothorax 
  and 
  of 
  the 
  

   elytra 
  is 
  sprinkled 
  with 
  numerous 
  scales, 
  not 
  as 
  closely 
  set, 
  however, 
  

   as 
  those 
  on 
  the 
  marginal 
  and 
  juxta-sutural 
  bands, 
  and 
  these 
  scales 
  

   have 
  a 
  more 
  golden 
  sheen 
  than 
  in 
  the 
  male 
  ; 
  the 
  hind 
  legs 
  are 
  also 
  

   robust.

  The

  and 
  less 
  brightly 
  scaly.
