  Head 
  and 
  prothorax 
  black, 
  the 
  latter 
  is 
  clothed 
  with 
  dense 
  black 
  

   hairs 
  interspersed 
  with 
  white, 
  lanceolate 
  not 
  very 
  dense 
  scales 
  ; 
  

   elytra 
  reddish 
  brown, 
  clothed 
  with 
  a 
  dense 
  but 
  short 
  black 
  pubes- 
  

   cence, 
  and 
  with 
  somewhat 
  closely 
  set, 
  and 
  rather 
  large 
  ovate 
  scales, 
  

   white 
  in 
  the 
  male, 
  flavescent 
  in 
  the 
  female 
  ; 
  head 
  rugose, 
  clypeus 
  not 
  

   much 
  attenuated 
  laterally 
  towards 
  the 
  tip 
  where 
  it 
  is 
  strongly 
  bi-den- 
  

   tate 
  ; 
  prothorax 
  rugulose, 
  but 
  having 
  the 
  same 
  shape 
  as 
  the 
  preceding 
  

   species 
  ; 
  scutellum 
  as 
  broad 
  as 
  long, 
  not 
  scaly, 
  but 
  pilose 
  ; 
  elytra 
  

   broadly 
  ampliated 
  laterally, 
  humeral 
  callus 
  strongly 
  developed 
  and 
  

   prolonged 
  longitudinally 
  as 
  far 
  as 
  the 
  median 
  part 
  of 
  the 
  elytra, 
  

   there 
  are 
  on 
  each 
  side 
  two 
  deep, 
  broad, 
  longitudinal 
  impressions 
  

   divided 
  by 
  a 
  costate 
  interval 
  near 
  the 
  base 
  ; 
  the 
  propygidium 
  has 
  a 
  

   transverse 
  band 
  of 
  whitish 
  squamose 
  hairs, 
  but 
  the 
  pygidium 
  has 
  no 
  

   scales 
  in 
  the 
  male 
  ; 
  in 
  the 
  female, 
  however, 
  it 
  has 
  two 
  patches 
  of 
  yellow 
  

   scales 
  ; 
  in 
  the 
  male 
  the 
  pygidium 
  slants 
  forwards 
  and 
  the 
  abdominal 
  

   segments 
  are 
  strongly 
  constricted 
  ; 
  the 
  sides 
  of 
  these 
  abdominal 
  

   segments 
  are 
  fringed 
  with 
  dense 
  white 
  hairs 
  ; 
  the 
  hind 
  legs 
  are 
  red 
  in 
  

   both 
  sexes 
  ; 
  the 
  anterior 
  tibiae 
  have 
  three 
  very 
  sharp 
  outer 
  teeth 
  

   which 
  are 
  quite 
  straight, 
  the 
  two 
  apical 
  ones 
  are 
  nearly 
  connate 
  at 
  

   base, 
  and 
  the 
  third 
  is 
  equally 
  long 
  and 
  sharp, 
  but 
  very 
  much 
  broader 
  

   at 
  the 
  base 
  ; 
  in 
  the 
  male 
  the 
  hind 
  femora 
  are 
  very 
  swollen 
  and 
  

   the 
  trochanters 
  are 
  not 
  spinose 
  ; 
  the 
  tibiae 
  are 
  compressed, 
  nearly 
  

   straight 
  inwardly 
  and 
  swollen 
  and 
  emarginate 
  on 
  the 
  outer 
  face 
  

   near 
  the 
  apex, 
  the 
  upper 
  angle 
  of 
  the 
  emargination 
  being 
  dentate, 
  

   in 
  the 
  inner 
  face 
  it 
  is 
  somewhat 
  shallowly 
  scooped 
  and 
  has 
  a 
  

   distinct 
  median 
  tooth, 
  and 
  the 
  two 
  apices 
  of 
  the 
  tibiae 
  are 
  produced 
  

   into 
  a 
  sharp 
  tooth, 
  the 
  one 
  on 
  the 
  upper 
  side 
  is 
  very 
  long 
  and 
  much 
  

   longer 
  than 
  the 
  upper 
  which 
  is 
  shorter 
  but 
  much 
  broader 
  than 
  the 
  

   apical 
  spur 
  ; 
  the 
  latter 
  is 
  situated 
  close 
  to 
  it 
  and 
  is 
  very 
  distinct 
  ; 
  

   the 
  four 
  basal 
  joints 
  of 
  the 
  hind 
  tarsi 
  are 
  equal 
  in 
  length 
  but 
  very 
  

   short 
  and 
  plainly 
  soldered, 
  the 
  fifth 
  is 
  nearly 
  twice 
  as 
  long 
  as 
  all 
  

   the 
  four 
  together, 
  and 
  is 
  armed 
  with 
  a 
  broad, 
  sharply 
  triangular 
  

   tooth 
  beneath, 
  the 
  claw 
  is 
  as 
  long 
  as 
  the 
  apical 
  joint, 
  slightly 
  sinuate,
