  Male 
  : 
  This 
  species 
  is 
  so 
  closely 
  allied 
  to 
  H. 
  vulpinus, 
  that 
  it 
  is 
  

   sometimes 
  difficult 
  to 
  differentiate 
  the 
  two. 
  The 
  shape, 
  vestiture, 
  

   and 
  disposition 
  of 
  the 
  scales 
  are 
  similar, 
  the 
  colour 
  of 
  the 
  elytra 
  and 
  

   legs 
  is 
  often 
  metallic 
  black, 
  the 
  scales 
  are 
  often 
  whitish, 
  but 
  the 
  

   distinctive 
  character 
  consists 
  in 
  the 
  presence 
  of 
  a 
  distinct 
  spinose 
  

   tooth 
  in 
  the 
  inner 
  part 
  of 
  the 
  knee, 
  and 
  of 
  two 
  distinct 
  ones, 
  facing 
  

   each 
  other 
  at 
  the 
  basal 
  part 
  of 
  the 
  tibiae, 
  at 
  the 
  beginning 
  of 
  the 
  

   grooved 
  part. 
  

  

  Female 
  similar 
  to 
  that 
  of

  vulpinus.

  a 
  faint 
  metallic 
  tinge 
  on 
  the

   chestnut-brown,

  sub- 
  

   velvety 
  coating 
  ; 
  clypeus 
  with 
  the 
  angles 
  dentate, 
  but 
  having 
  almost 
  

   no 
  trace 
  of 
  median 
  teeth 
  ; 
  the 
  head 
  and 
  prothorax 
  are 
  covered 
  with 
  

   villose 
  navescent 
  hairs,

  not 
  very 
  

   dense 
  appressed 
  squamose

  densely 
  scaly

  beneath, 
  at 
  about 
  the

   part,

  sub- 
  vertical 
  tooth, 
  which 
  is 
  not 
  connected 
  with 
  the 
  trochanters, 
  

   and 
  a 
  sub-transverse 
  one 
  close 
  to 
  the 
  knee, 
  the 
  articulation 
  of 
  which 
  

   is 
  not 
  dentate
