  Male 
  : 
  Very 
  similar 
  to 
  H. 
  promontorii 
  ; 
  the 
  hind 
  femora 
  and 
  

   tibiae 
  have 
  the 
  same 
  shape, 
  but 
  the 
  body 
  is 
  a 
  little 
  more 
  elongate, 
  

   owing 
  to 
  the 
  base 
  of 
  the 
  elytra 
  not 
  being 
  broader 
  than 
  that 
  of 
  

   the 
  prothorax 
  ; 
  the 
  clypeus 
  is 
  not 
  dentate 
  laterally, 
  the 
  prothorax 
  

   is 
  distinctly 
  grooved 
  in 
  the 
  posterior 
  part, 
  the 
  punctures 
  are 
  much 
  

   more 
  scattered, 
  deeper 
  and 
  not 
  scabrose 
  ; 
  the 
  elytra 
  have 
  on 
  each 
  

   side 
  four 
  narrow 
  bands 
  of 
  white 
  scales 
  and 
  are 
  redder 
  than 
  in 
  

   H. 
  promontorii 
  but 
  the 
  punctuation 
  is 
  the 
  same 
  ; 
  pygidium 
  black, 
  not 
  

   scaly 
  ;

  scaly

  legs 
  black.

   Male 
  : 
  Black, 
  with 
  the 
  elytra 
  and 
  the 
  hind 
  legs 
  shining 
  red 
  ; 
  

   prothorax 
  villose 
  and 
  having 
  a 
  median 
  longitudinal 
  line 
  of 
  white 
  

   scales 
  ; 
  elytra 
  with 
  a 
  discoidal 
  line 
  of 
  similar 
  scales 
  ; 
  scutellum, 
  

   abdomen 
  and 
  pygidium 
  clothed 
  with 
  contiguous 
  white 
  scales, 
  but 
  the 
  

   latter 
  has 
  a 
  median 
  longitudinal 
  denuded 
  line 
  which 
  does 
  not 
  reach 
  to 
  

   the 
  apex 
  ; 
  clypeus 
  sharply 
  quadri-dentate, 
  the 
  teeth 
  equal 
  ; 
  head 
  and 
  

   prothorax 
  very 
  closely 
  scabroso-punctate, 
  the 
  pubescence 
  is 
  very 
  long 
  

   and 
  greyish 
  and 
  along 
  the 
  lateral 
  and 
  basal 
  margins 
  there 
  is 
  a 
  narrow 
  

   line 
  of 
  white 
  scales 
  ; 
  elytra 
  elongate, 
  attenuate 
  towards 
  the 
  apex, 
  

   but 
  not 
  deeply 
  sinuate 
  below 
  the 
  shoulder, 
  they 
  are 
  cicatricose 
  and 
  

   roughly 
  punctate, 
  and 
  have 
  a 
  narrow 
  discoidal 
  impressed 
  interval 
  

   filled 
  with 
  the 
  white 
  scales, 
  but 
  they 
  are 
  not 
  costulate 
  ; 
  the 
  hind 
  

   femora 
  are 
  only 
  moderately 
  robust 
  and 
  simple, 
  the 
  hind 
  tibiae 
  are 
  

   long, 
  strongly 
  swollen 
  inwardly, 
  sharply 
  but 
  briefly 
  mucronate 
  in 
  the 
  

   inner 
  apical 
  part, 
  and 
  quite 
  similar 
  to 
  those 
  of 
  H. 
  ditus 
  (pi. 
  xlii., 
  

   fig. 
  39) 
  ; 
  apical 
  joint 
  of 
  hind 
  tarsi 
  and 
  claw 
  very 
  long. 
  The 
  shape 
  of 
  

   the 
  hind 
  tibiae 
  is 
  nearly 
  similar 
  to 
  that 
  of 
  H. 
  ditus 
  (pi. 
  xlii., 
  fig. 
  39).
