  ; 
  the 
  scales 
  on 
  the

  are 
  

   very 
  small, 
  very 
  elongate, 
  somewhat 
  in 
  the 
  shape 
  of 
  a 
  squamose 
  hair, 
  

   and 
  the 
  whole 
  pygidium, 
  which 
  is 
  very 
  strongly 
  convex 
  in 
  the 
  centre, 
  

   is 
  glabrous 
  and 
  shining

  The 
  female 
  is

  Male 
  : 
  This 
  species 
  is 
  very 
  closely 
  allied 
  to 
  H. 
  murinus 
  ; 
  the 
  

   shape, 
  size, 
  and 
  sculpture 
  are 
  similar, 
  but 
  the 
  scales 
  with 
  which 
  the 
  

   elytra 
  are 
  very 
  abundantly 
  sprinkled 
  are 
  rounder 
  and 
  broader, 
  the 
  

   hind 
  legs 
  are 
  black, 
  and 
  the 
  pygidium 
  is 
  much 
  less 
  convex 
  in 
  

   the 
  male 
  than 
  in 
  H. 
  murinus, 
  where 
  it 
  is 
  conspicuously 
  so. 
  The 
  

   females 
  of 
  the 
  two 
  species 
  cannot 
  be 
  distinguished 
  from 
  each 
  other.

  clypeus 
  very 
  

   slightly 
  bi-dentate 
  in 
  the 
  median 
  part 
  ; 
  head 
  and 
  prothorax 
  covered 
  

   with 
  a 
  short 
  flavescent 
  pubescence

  ; 
  scu- 
  

   tellum 
  and 
  elytra 
  also 
  covered 
  with 
  contiguous 
  yellow 
  scales 
  ; 
  the 
  

   elytra 
  are 
  not 
  very 
  elongate 
  ; 
  the 
  propygidium, 
  the 
  whole 
  of 
  the 
  

   pygidium 
  and 
  the 
  sides 
  of 
  the 
  abdomen 
  are 
  covered 
  with 
  yellow 
  

   scales 
  ; 
  the 
  pygidium 
  is 
  very 
  convex 
  at 
  the 
  base 
  ; 
  the 
  hind 
  femora 
  

   are 
  very 
  swollen, 
  like 
  those 
  of 
  H. 
  longipes 
  and 
  H. 
  murinus, 
  but 
  the 
  

   trochanters 
  are 
  produced

  very 
  long 
  spine 
  ; 
  the

  tibiae 
  are 
  

   not 
  deeply 
  grooved 
  underneath, 
  and 
  the 
  inner 
  edge 
  of 
  the 
  groove 
  has 
  a 
  

   sharp, 
  median 
  tooth, 
  equi-distant 
  from 
  the 
  apical 
  curved 
  mucro, 
  and 
  

   from 
  the 
  base 
  ; 
  the 
  outer 
  margin 
  of 
  the 
  groove 
  is 
  not 
  well 
  defined, 
  

   and 
  is 
  not
