  sides 
  rounded, 
  

   sinuate 
  behind 
  the

  converging 
  anteriorly 
  towards 
  the 
  apex, 
  

   the 
  hinder 
  angles 
  produced, 
  subacute

  above 
  convex, 
  smooth, 
  

   impunctate 
  ; 
  disk 
  impressed

  side 
  with 
  a 
  deep

   Elytra 
  broadly 
  ovate, 
  strongly 
  dilated 
  towards 
  the 
  apex, 
  their 
  

   apices 
  conjointly 
  obtusely 
  rounded; 
  above 
  convex, 
  subventricose 
  

   behind 
  the 
  middle, 
  transversely 
  depressed 
  below 
  the 
  basilar 
  space, 
  

   rather 
  strongly

  not 
  very 
  closely 
  punctured, 
  the

  The 
  above 
  insect, 
  of 
  which 
  I 
  only 
  know 
  a 
  single 
  male 
  

   and 
  female, 
  may 
  be 
  known 
  from 
  its 
  congeners 
  by 
  its 
  

   larger 
  size, 
  and 
  more 
  strongly 
  punctured 
  elytra. 
  From 
  

   D. 
  suhsimilis, 
  with 
  which 
  species 
  it 
  agrees 
  in 
  the 
  punctua- 
  

   tion 
  of 
  its 
  elytra, 
  it 
  differs 
  in 
  the 
  relative 
  length 
  of 
  the 
  

   third 
  and 
  fourth 
  joints 
  of 
  the 
  antennse.
