  the 
  female, 
  and 
  having 
  in 
  the 
  median 
  part 
  of 
  the 
  disk 
  four 
  equi- 
  

   distant 
  patches 
  of 
  appressed 
  scales 
  disposed 
  transversely 
  ; 
  elytra 
  

   livid 
  brown 
  in 
  the 
  male, 
  sub-ochraceous 
  in 
  the 
  female, 
  having 
  on 
  

   each 
  side 
  a 
  sutural 
  and 
  a 
  supra-marginal 
  band 
  connecting 
  along 
  the 
  

   apical 
  part, 
  and 
  a 
  discoidal 
  one 
  reaching 
  from 
  the 
  base 
  to 
  past 
  the 
  

   middle 
  and 
  composed 
  of 
  appressed, 
  lanceolate 
  scales, 
  white 
  in 
  the 
  

   male, 
  yellow 
  in 
  the 
  female 
  ; 
  propygidium 
  and 
  pygidium 
  entirely 
  

   covered 
  with 
  dense 
  round 
  scales 
  ; 
  abdominal 
  segments 
  covered 
  with 
  

   scales 
  ; 
  legs 
  black, 
  scaly 
  ; 
  the 
  head 
  is 
  narrowed 
  laterally, 
  sub-acumi- 
  

   nate, 
  slightly 
  emarginate 
  at 
  tip 
  and 
  with 
  the 
  two 
  angles 
  of 
  the 
  

   clypeus 
  not 
  highly 
  dentate 
  ; 
  the 
  prothorax 
  is 
  deeply 
  punctate, 
  and 
  is 
  

   gradually 
  narrowed 
  laterally 
  from 
  the 
  base 
  to 
  the 
  apex 
  and 
  not 
  

   sinuate, 
  the 
  two 
  median 
  scaly 
  patches 
  are 
  sometimes 
  obliterated, 
  but 
  

   the 
  angles 
  of 
  the 
  anterior 
  part 
  are 
  more 
  broadly 
  scaly 
  than 
  the 
  

   centre 
  of 
  the 
  anterior 
  margin 
  ; 
  in 
  the 
  male 
  the 
  elytra 
  are 
  more 
  

   parallel 
  than 
  in 
  the 
  previous 
  species, 
  the 
  humeral 
  callus 
  is 
  strong, 
  

   but 
  short, 
  and 
  there 
  are 
  on 
  each 
  side 
  three 
  longitudinal 
  very 
  shallow 
  

   lines 
  which 
  are 
  filled 
  with 
  the 
  appressed 
  scales, 
  they 
  are 
  rugulose 
  

   and 
  glabrous 
  except 
  for 
  a 
  row 
  of 
  closely 
  set 
  black 
  bristles 
  along 
  the 
  

   suture 
  and 
  the 
  outer 
  margin 
  ; 
  the 
  pygidium 
  is 
  vertical, 
  the 
  abdominal 
  

   segments 
  are 
  not 
  constricted 
  in 
  the 
  centre 
  ; 
  the 
  anterior 
  tibiae 
  are 
  tri- 
  

   dentate 
  outwardly, 
  the 
  two 
  anterior 
  teeth 
  are 
  almost 
  connate 
  at 
  the 
  

   base, 
  and 
  the 
  basal 
  tooth, 
  which 
  is 
  more 
  robust, 
  is 
  situated 
  at 
  a 
  long 
  

   distance 
  from 
  the 
  two 
  apical 
  ones 
  ; 
  the 
  hind 
  trochanters 
  are 
  simple 
  

   and 
  the 
  femora 
  thick 
  and 
  swollen 
  ; 
  the 
  tibiae 
  are 
  very 
  swollen, 
  and 
  

   are 
  produced 
  inwardly 
  at 
  a 
  short 
  distance 
  from 
  the 
  apex 
  into 
  a 
  

   triangular 
  dentate 
  process 
  scooped 
  beneath, 
  and 
  there 
  is 
  no 
  trace 
  

   left 
  of 
  the 
  inner 
  spur 
  ; 
  the 
  four 
  basal 
  joints 
  are 
  fused 
  into 
  a 
  short 
  

   one, 
  but 
  the 
  suture 
  is 
  still 
  indicated 
  by 
  a 
  row 
  of 
  scales, 
  and 
  under- 
  

   neath 
  there 
  is 
  a 
  sharp 
  spur 
  ; 
  the 
  fifth 
  joint 
  is 
  long, 
  very 
  robust, 
  

   strongly 
  dentate 
  beneath, 
  and 
  the 
  claw, 
  which 
  is 
  longer 
  than 
  all 
  the 
  

   joints 
  of 
  the 
  tarsi 
  put 
  together, 
  is 
  sinuate 
  and 
  has 
  a 
  distinct 
  tooth 
  

   underneath 
  ; 
  the 
  female 
  is 
  much 
  smaller 
  than 
  the 
  male, 
  and 
  the 
  hind 
  

   legs 
  are 
  slender 
  in 
  comparison, 
  and 
  simple.
