  Heterochelus 
  promontorii, 
  n. 
  spec. 
  

  

  Male 
  : 
  Black, 
  with 
  the 
  elytra 
  chestnut-red 
  or 
  dark 
  bronze 
  ; 
  the 
  

   scutellum, 
  the 
  propygidium, 
  and 
  the 
  abdomen 
  are 
  clothed 
  with 
  dense 
  

   yellowish 
  scales, 
  but 
  the 
  pygidium 
  is 
  glabrous 
  and 
  shining, 
  and 
  the 
  

   elytra 
  have 
  a 
  sutural 
  band 
  of 
  similar 
  scales 
  beginning 
  at 
  about 
  

   the 
  median 
  part 
  and 
  continued 
  on 
  the 
  apical, 
  and 
  a 
  discoidal 
  one 
  

   reaching 
  from 
  the 
  base 
  to 
  the 
  middle 
  ; 
  head 
  and 
  prothorax 
  scabrose, 
  

   very 
  briefly 
  pubescent 
  and 
  not 
  scaly, 
  clypeus 
  dentate 
  on 
  each 
  side 
  

   but 
  not 
  denticulate 
  in 
  the 
  centre 
  ; 
  elytra 
  distinctly 
  bi-costulate 
  on 
  

   each 
  side, 
  second 
  costa 
  disappearing 
  at 
  about 
  the 
  median 
  part, 
  the 
  

   intervening 
  space 
  is 
  filled 
  with 
  the 
  scales, 
  which 
  are 
  not 
  very 
  dense 
  on 
  

   the 
  discoidal 
  one 
  or 
  along 
  the 
  outer 
  margin 
  ; 
  hind 
  femora 
  very 
  robust, 
  

   the 
  trochanters 
  are 
  simple, 
  but 
  the 
  inner 
  tooth 
  of 
  the 
  knee 
  is 
  

   developed 
  into 
  a 
  distinct 
  spine, 
  the 
  short 
  hind 
  tibiae 
  are 
  curved, 
  

   ampliated, 
  grooved 
  underneath 
  and 
  strongly 
  dentate 
  on 
  each 
  side 
  of 
  

   the 
  base, 
  but 
  have 
  the 
  outer 
  tooth 
  set 
  further 
  from 
  the 
  base 
  than 
  the 
  

   inner, 
  the 
  inner 
  mucro 
  is 
  long 
  and 
  curved, 
  almost 
  hamate 
  ; 
  claws 
  as 
  

   in 
  H. 
  viridicollis. 
  

  

  Female 
  : 
  Like 
  the 
  male, 
  and 
  also 
  with 
  the 
  pygidium 
  without 
  scales 
  

   and 
  sub-glabrous 
  ; 
  the 
  scales 
  on 
  the 
  elytra 
  are 
  replaced 
  by 
  sub- 
  

   squamose 
  hairs 
  which 
  are 
  not 
  conspicuous. 
  

  

  This 
  species 
  is 
  not 
  unlike 
  H. 
  rufimanns, 
  which 
  has 
  also 
  the 
  

   denuded 
  pygidium, 
  but 
  it 
  differs 
  in 
  the 
  sculpture 
  of 
  the 
  elytra 
  and 
  

   in 
  the 
  shape 
  of 
  the 
  hind 
  tibiae.

  orange 
  squamose

  femora 
  robust,

  of 
  

   trochanters 
  fused 
  with 
  the

  but 
  projecting 
  a 
  little 
  towards 
  the 
  

   median 
  part,

  at 
  a
