  the 
  elytra 
  clothed 
  with 
  yellow 
  scales 
  but 
  

   having 
  on 
  each

  an 
  oblique, 
  elongate, 
  sub- 
  

   parallel 
  black 
  or 
  dark 
  brown 
  patch 
  ; 
  legs 
  reddish 
  brown 
  ; 
  clypeus 
  

   indistinctly 
  bi-dentate 
  in 
  the 
  median 
  part 
  ; 
  prothorax 
  covered 
  with 
  

   lanciform 
  yellow 
  scales 
  moderately 
  dense 
  but 
  looking 
  more 
  like 
  

   strongly 
  squamiform 
  hairs 
  ; 
  scutellum 
  densely 
  scaly 
  ; 
  the 
  scales 
  on 
  

   the 
  elytra, 
  which 
  are 
  not 
  costate, 
  are 
  small 
  and 
  very 
  dense, 
  and 
  the 
  

   postical 
  brown 
  patch 
  reaches 
  from 
  the 
  apical 
  callosity 
  to 
  about 
  one- 
  

   fifth 
  of 
  the 
  whole 
  length 
  ; 
  the 
  propygidium 
  and 
  sides 
  of 
  the 
  abdomen 
  

   have 
  yellow 
  scales, 
  but 
  the 
  pygidium 
  is 
  piceous 
  red, 
  and 
  not 
  scaly 
  ; 
  

   the 
  hind 
  legs 
  are 
  robust, 
  the 
  trochanters 
  are 
  very 
  briefly 
  spinose, 
  

   and 
  the 
  knees 
  are 
  briefly 
  and 
  equally 
  dentate 
  on 
  each 
  side 
  ; 
  the 
  

   hind 
  tibiae 
  are 
  broadly 
  and 
  somewhat 
  deeply 
  excavated 
  underneath 
  

   for 
  nearly 
  all 
  the 
  length, 
  but 
  the 
  angle 
  of 
  the 
  inner 
  margin 
  is 
  more 
  

   strongly 
  dentate 
  than 
  the 
  outer, 
  and 
  the 
  mucro 
  is 
  much 
  curved 
  and 
  

   long 
  ; 
  hind 
  claws

  single. 
  

  

  Female 
  : 
  According 
  to 
  Burmeister, 
  the 
  female, 
  which 
  I 
  have 
  not 
  

   been 
  able 
  to 
  obtain, 
  is 
  sub-squamose, 
  and 
  the 
  pygidium 
  is 
  clothed 
  

   with 
  squamiform 
  scales.

  Male 
  : 
  This 
  species 
  is 
  closely 
  allied 
  to 
  H. 
  armatus 
  ; 
  but 
  it 
  is 
  a 
  little 
  

   smaller 
  ; 
  the 
  two 
  median 
  teeth 
  of 
  the 
  clypeus 
  are 
  stronger 
  and 
  equal 
  

   in 
  height 
  to 
  the 
  lateral 
  ones 
  ; 
  the 
  vestiture 
  and 
  the 
  disposition 
  of 
  the 
  

   yellow 
  scales 
  are 
  similar, 
  but 
  the 
  pygidium 
  is 
  nude 
  and 
  shining,
