  distinctly 
  emarginate 
  and 
  angular, 
  and 
  with 
  the 
  apical 
  teeth 
  broad 
  

   and 
  strongly 
  renexed 
  ; 
  prothorax 
  gradually 
  narrowed 
  from 
  the 
  base 
  

   to 
  the 
  apex, 
  but 
  more 
  distinctly 
  so 
  in 
  the 
  anterior 
  part 
  ; 
  deeply 
  

   and 
  closely 
  punctate, 
  and 
  densely 
  hairy 
  like 
  the 
  head, 
  the 
  scales 
  

   form 
  a 
  not 
  very 
  distinct 
  margin 
  all 
  round, 
  but 
  those 
  on 
  the 
  disk 
  are 
  

   few, 
  and 
  very 
  remote 
  ; 
  scutellum 
  moderately 
  elongate, 
  non-scaly 
  ; 
  

   elytra 
  not 
  much 
  ampliated 
  below 
  the 
  humeral 
  part, 
  but 
  distinctly 
  

   narrowed 
  towards 
  the 
  apex, 
  faintly 
  sulcate 
  longitudinally 
  on 
  each 
  

   side 
  of 
  the 
  humeral 
  angle 
  which 
  is 
  well 
  developed, 
  and 
  narrowly 
  

   striate 
  along 
  the 
  suture, 
  broadly, 
  not 
  deeply, 
  and 
  very 
  irregularly 
  

   punctate, 
  glabrous 
  except 
  for 
  the 
  usual 
  sutural 
  and 
  outer 
  marginal 
  

   row 
  of 
  bristles, 
  and 
  the 
  white 
  scales 
  with 
  which 
  it 
  is 
  sprinkled 
  

   although 
  numerous, 
  are 
  not 
  at 
  all 
  closely 
  set 
  ; 
  the 
  propygidium 
  is 
  

   covered 
  with 
  closely 
  set 
  white 
  scales, 
  but 
  the 
  pygidium, 
  which 
  is 
  

   vertical, 
  is 
  bare 
  ; 
  the 
  abdominal 
  segments 
  are 
  not 
  much 
  constricted 
  in 
  

   the 
  centre 
  and 
  are 
  scaly, 
  and 
  the 
  pectus 
  is 
  very 
  pubescent 
  ; 
  the 
  

   anterior 
  tibiae 
  are 
  tri-dentate, 
  the 
  two 
  anterior 
  teeth 
  are 
  closely 
  set, 
  

   but 
  not 
  connate, 
  and 
  the 
  basal 
  one 
  is 
  stronger 
  and 
  set 
  at 
  some 
  

   distance 
  from 
  the 
  apical 
  ones 
  ; 
  the 
  hind 
  trochanters 
  are 
  somewhat 
  

   dentate, 
  the 
  femora 
  are 
  thick, 
  but 
  not 
  equal 
  in 
  proportion 
  to 
  the 
  

   size 
  of 
  the 
  tibiae 
  which 
  are 
  extremely 
  swollen 
  and 
  broadly 
  triangular 
  

   inwardly, 
  the 
  apex 
  of 
  the 
  triangle 
  having 
  a 
  hamate 
  tooth, 
  and 
  at 
  the 
  

   tip 
  there 
  is, 
  next 
  to 
  the 
  inner 
  spur 
  which 
  is 
  long 
  and 
  slender, 
  a 
  short 
  

   but 
  distinct 
  tooth 
  ; 
  the 
  four 
  basal 
  joints 
  of 
  the 
  tibiae 
  are 
  short 
  but 
  

   broad, 
  soldered, 
  and 
  nearly 
  as 
  wide 
  as 
  the 
  fifth 
  joint 
  which 
  is 
  broad 
  

   but 
  not 
  swollen, 
  the 
  apical 
  claw 
  has 
  a 
  very 
  sharp 
  triangular 
  tooth 
  

   beneath, 
  and 
  is 
  distinctly 
  curved.
