  marginal, 
  slightly 
  longer 
  but 
  a 
  little 
  narrower 
  one, 
  as 
  well 
  as 
  a 
  

   third 
  rudimentary 
  and 
  basal, 
  often, 
  however, 
  obliterated 
  ; 
  in 
  the 
  

   female 
  these 
  bands 
  are 
  somewhat 
  flavescent 
  ; 
  propygidium 
  clothed 
  

   with 
  white 
  scales, 
  but 
  having 
  a 
  broadly 
  triangular 
  black 
  apical 
  patch, 
  

   pygidium 
  clothed 
  laterally 
  and 
  along 
  the 
  base 
  with 
  white 
  scales, 
  the 
  

   denuded 
  interval 
  broad 
  ; 
  legs 
  black, 
  pectus 
  hairy, 
  abdominal 
  seg- 
  

   ments 
  greatly 
  constricted 
  and 
  covered 
  with 
  white 
  scales 
  ; 
  in 
  the 
  

   female 
  the 
  parts 
  of 
  the 
  propygidium 
  and 
  pygidium, 
  which 
  in 
  the 
  

   male 
  are 
  black 
  or 
  denuded, 
  are 
  brown, 
  turning 
  to 
  yellow 
  ; 
  head 
  very 
  

   hairy, 
  clypeus 
  short, 
  slightly 
  sinuate 
  laterally 
  and 
  with 
  the 
  two 
  apical 
  

   teeth 
  very 
  long 
  ; 
  prothorax 
  rugose 
  like 
  the 
  head, 
  also 
  densely 
  hairy, 
  

   very 
  obliquely 
  attenuated 
  latterly 
  in 
  the 
  anterior 
  part, 
  and 
  slightly 
  

   sinuated 
  past 
  the 
  median 
  part 
  ; 
  scutellum 
  very 
  elongate 
  and 
  sharp, 
  

   but 
  somewhat 
  broad 
  at 
  the 
  base, 
  sparingly 
  scaly 
  and 
  slightly 
  

   canaliculate 
  longitudinally 
  in 
  the 
  middle 
  ; 
  elytra 
  strongly 
  ampliated 
  

   laterally 
  past 
  the 
  humeral 
  part, 
  and 
  diagonally 
  attenuated 
  from 
  there, 
  

   the 
  humeral 
  callus 
  is 
  strongly 
  developed, 
  but 
  there 
  is 
  a 
  slight 
  depres- 
  

   sion 
  only 
  on 
  each 
  side 
  of 
  it 
  ; 
  the 
  discoidal 
  part 
  is 
  glabrous, 
  but 
  along 
  

   the 
  suture 
  and 
  the 
  outer 
  margin 
  there 
  is 
  a 
  series 
  of 
  somewhat 
  closely 
  

   set, 
  very 
  long 
  and 
  very 
  stiff 
  black 
  bristles 
  ; 
  in 
  the 
  female 
  these 
  bristles 
  

   are 
  finer, 
  denser, 
  shorter 
  and 
  flavescent, 
  and 
  the 
  intervals 
  between 
  

   the 
  scaly 
  patches 
  are 
  briefly 
  but 
  densely 
  pubescent 
  ; 
  anterior 
  tibiae 
  

   tri-dentate 
  outwardly, 
  the 
  two 
  apical 
  teeth 
  are 
  sub-connate, 
  and 
  the 
  

   basal 
  one 
  is 
  situate 
  far 
  from 
  them 
  ; 
  in 
  the 
  male 
  the 
  trochanters 
  of 
  the 
  

   posterior 
  legs 
  are 
  simple, 
  the 
  femora 
  are 
  strong, 
  the 
  tibiae 
  are 
  

   enormously 
  swollen 
  and 
  have 
  inwardly 
  a 
  sub-apical 
  short 
  tooth 
  

   situated 
  close 
  to 
  and 
  connate 
  with 
  the 
  apical 
  spur 
  which 
  is 
  very 
  

   long 
  and 
  sharp 
  ; 
  the 
  four 
  basal 
  joints 
  of 
  the 
  tarsi 
  are 
  fused 
  with 
  the 
  

   fifth 
  without 
  any 
  trace 
  of 
  a 
  suture, 
  and 
  this 
  unique 
  joint 
  has 
  beneath 
  

   a 
  strong 
  hamate 
  tooth 
  and 
  a 
  much 
  smaller 
  one 
  following 
  it, 
  the 
  claw 
  

   is 
  much 
  longer 
  than 
  the 
  joint, 
  and 
  bi-dentate 
  beneath 
  near 
  the 
  base 
  ; 
  

   in 
  the 
  female 
  the 
  hind 
  legs 
  are 
  normal 
  and 
  simple.

  In

  the 
  males 
  are 
  uniformly 
  without 
  

   the

  bands 
  on 
  the 
  elytra,

  a 
  few 
  white

  always 
  

   visible 
  near 
  the 
  base.
