  Male 
  : 
  Very 
  closely 
  allied 
  to

  the

  is 
  the

  a 
  little 
  more 
  metallic, 
  and 
  the 
  scales 
  are 
  paler 
  ; 
  the 
  elytra 
  

   are 
  distinctly 
  costate 
  ; 
  the 
  hind 
  femora 
  are 
  similar, 
  and 
  the 
  hind 
  

   tibiae 
  also, 
  but 
  the 
  pygidium 
  which 
  in 
  D. 
  consanguineus 
  is 
  entirely 
  

   covered 
  with 
  scales 
  has

  Male 
  : 
  Head 
  only 
  black, 
  the 
  body 
  light 
  testaceous 
  red, 
  the 
  hind 
  

   legs 
  with 
  a 
  metallic 
  tinge; 
  it 
  is 
  closely 
  allied 
  to 
  the 
  preceding 
  species, 
  

   and 
  is 
  likewise 
  clothed 
  with 
  yellow 
  scales 
  which 
  are, 
  however, 
  a 
  little 
  

   paler 
  ; 
  the 
  vestiture 
  of 
  the 
  head 
  and 
  prothorax 
  is 
  similar 
  ; 
  the 
  elytra 
  

   are 
  also 
  costate 
  with 
  the 
  costae 
  very 
  briefly 
  setulose, 
  but 
  the 
  pygidium 
  

   has 
  two 
  very 
  distinct 
  basal 
  brown 
  patches 
  which 
  are 
  entirely 
  absent 
  

   in 
  H. 
  mimus 
  ; 
  the 
  hind 
  femora 
  are 
  similar, 
  but 
  in 
  the 
  hind 
  tibiae 
  

   there 
  is 
  below 
  the 
  knee 
  a 
  distinctly 
  truncate 
  tooth 
  in 
  the 
  upper 
  

   margin 
  of 
  the 
  shallow 
  groove, 
  and 
  none 
  in 
  the 
  lower.

  very 
  feebly 
  dentate 
  in 
  the 
  middle; 
  

   the 
  hairs 
  covering 
  the 
  head 
  and 
  prothorax 
  are 
  very 
  short 
  and 
  partly 
  

   sub-appressed, 
  but 
  along 
  the

  of 
  the

  along 
  the 
  

   suture 
  and

  double 
  row 
  of 
  very 
  short
