  Male 
  : 
  Shape, 
  size, 
  and 
  sculpture 
  of 
  D. 
  simplicipes 
  ; 
  the 
  elytra, 
  

   however, 
  are 
  redder, 
  although 
  they 
  are 
  also 
  occasionally 
  infuscate, 
  

   or 
  even 
  black 
  ; 
  the 
  two 
  white 
  bands 
  of 
  scales 
  are 
  similar, 
  and 
  they 
  

   are 
  faintly 
  punctured, 
  with 
  the 
  punctures 
  somewhat 
  seriate 
  ; 
  the 
  

   scutellum 
  has 
  no 
  scales, 
  but 
  it 
  has 
  often 
  some 
  flavescent, 
  some- 
  

   what 
  remote 
  appressed 
  hairs; 
  the 
  hind 
  legs 
  are, 
  however, 
  very 
  

   different 
  and 
  approximate 
  to 
  those 
  of 
  D. 
  luctuosus 
  ; 
  the 
  hind 
  femora 
  

   are 
  very 
  robust 
  and 
  have 
  the 
  spine 
  of 
  the 
  trochanters 
  strong, 
  sub- 
  

   horizontal 
  but 
  not 
  very 
  long, 
  and 
  above 
  the 
  point 
  of 
  the 
  spine 
  there 
  

   is 
  a 
  short 
  but 
  very 
  distinct 
  femoral 
  tooth 
  ; 
  the 
  hind 
  tibiae 
  are 
  arcuate, 
  

   shallowly 
  grooved 
  underneath 
  with 
  the 
  two 
  edges 
  simple, 
  equal, 
  and 
  

   projecting 
  at 
  the 
  apex 
  in 
  a 
  very 
  long, 
  arcuate 
  inner 
  mucro, 
  thus 
  

   resembling 
  entirely 
  those 
  of 
  D. 
  luctuosus.

  the

   pubescent.

  Black, 
  not 
  distinctly 
  metallic, 
  shining, 
  elytra 
  testaceous 
  and 
  having 
  

   some 
  traces 
  left 
  on 
  each 
  side 
  of 
  the 
  bands 
  of 
  obliquely 
  disposed 
  

   greyish-white 
  scales, 
  pygidium 
  clothed 
  with 
  yellow 
  scales, 
  anterior 
  

   legs 
  reddish 
  ; 
  head 
  and 
  prothorax 
  clothed 
  with 
  fulvous 
  hairs, 
  scutellum 
  

   without 
  scales 
  ; 
  elytra 
  with 
  two 
  faint 
  costules 
  on 
  each 
  side 
  separating 
  

   the 
  three 
  bands 
  of 
  scales, 
  the 
  juxta-sutural 
  of 
  which 
  is 
  the 
  broadest 
  

   and 
  the 
  most 
  distinct, 
  they 
  are 
  punctulate, 
  not 
  convex 
  at 
  the 
  base, 
  

   normally 
  narrowed 
  laterally 
  towards 
  the 
  apex 
  ; 
  propygidium 
  scaly 
  at 
  

   apex, 
  abdominal 
  segments 
  with 
  a 
  patch 
  of 
  flavescent 
  scales 
  ; 
  hind 
  

   femora 
  robust, 
  but 
  not 
  very 
  swollen, 
  simple, 
  but 
  the 
  two 
  teeth 
  of 
  the 
  

   articulation 
  of 
  the 
  knee 
  are 
  very 
  sharp, 
  and 
  the 
  trochanters 
  have 
  a 
  

   very 
  short 
  spine 
  ; 
  the 
  hind 
  tibiae 
  are 
  conspicuously 
  emarginate 
  at 
  the 
  

   base 
  for 
  a 
  third 
  of 
  the 
  length, 
  compressed 
  and 
  laminate 
  underneath 
  

   with 
  the 
  upper 
  angle 
  of 
  the 
  lamina 
  very 
  sharp, 
  and 
  the 
  apical 
  one 
  

   produced 
  into 
  a 
  moderately 
  long 
  inner 
  mucro 
  ; 
  the 
  bristles 
  of 
  the 
  hind 
  

   tarsi 
  are 
  fulvous.
