  Male 
  : 
  Eesembles 
  D. 
  dentines 
  in 
  general 
  build 
  and 
  also 
  in 
  the 
  

   shape 
  of 
  the 
  hind 
  legs, 
  but 
  it 
  is 
  differentiated 
  by 
  the 
  colour 
  of 
  the 
  

   body 
  which 
  is 
  black, 
  but 
  has 
  a 
  greenish, 
  metallic 
  tinge, 
  the 
  elytra 
  

   are 
  redder 
  and 
  opaque, 
  but 
  clothed 
  with 
  the 
  same 
  greyish, 
  appressed 
  

   pubescence, 
  and 
  the 
  legs 
  are 
  of 
  the 
  same 
  colour 
  as 
  the 
  elytra. 
  

  

  Female 
  : 
  Like 
  the 
  female 
  of 
  D. 
  dentipes, 
  but 
  it 
  has 
  two 
  distinct 
  

   denuded 
  patches 
  on 
  each 
  side 
  of 
  the 
  pygidium. 
  

  

  Although 
  very 
  closely 
  allied 
  to 
  D. 
  dentipes 
  this 
  species 
  is 
  different. 
  

   It 
  appears 
  also 
  later 
  in 
  the 
  spring.

  The 
  description 
  of 
  D. 
  dentipes 
  suits 
  also 
  this 
  species, 
  but 
  the 
  

   facies 
  is 
  not 
  so 
  robust, 
  the 
  colour 
  of 
  the 
  prothorax 
  is 
  slightly 
  

   greenish 
  black, 
  that 
  of 
  the 
  elytra 
  varies 
  also 
  from 
  red-brown 
  to 
  

   fuscous, 
  but 
  instead 
  of 
  having 
  appressed 
  hairs 
  only 
  they 
  have 
  a 
  

   juxta-sutural 
  band 
  of 
  greyish-white 
  ones 
  not 
  closely 
  set 
  and 
  often 
  

   partly 
  obliterated 
  ; 
  the 
  pygidium 
  of 
  the 
  female 
  has 
  two 
  denuded 
  

   lateral 
  patches 
  like 
  the 
  female 
  of 
  D. 
  expansus 
  ; 
  the 
  hind 
  tibiae 
  of 
  

   the 
  male 
  are 
  sharply 
  carinate 
  underneath 
  and 
  not 
  grooved, 
  but 
  

   the 
  median 
  inner 
  tooth 
  and 
  the 
  apical 
  mucro 
  are 
  similar 
  to 
  those 
  

   •of 
  the 
  two 
  preceding 
  species.

  chestnut-brown,

  are 
  as 
  in 
  D. 
  dentipes, 
  but 
  the 
  elytra 
  are 
  narrower 
  though 
  

  

  ^equal 
  in 
  length, 
  distinctly 
  bi-costulate 
  on
