  Georgia. 
  Of 
  the 
  same 
  appearance 
  as 
  the 
  last, 
  from 
  which 
  it 
  only 
  differs 
  by 
  the 
  

   thorax 
  being 
  hardly 
  perceptibly 
  impressed 
  at 
  the 
  angles, 
  instead 
  of 
  being 
  deeply 
  ex- 
  

   cavated. 
  Perhaps 
  this 
  may 
  be 
  a 
  sexual 
  character. 
  

  

  D. 
  punctatorugosa 
  Blanch, 
  having 
  the 
  front 
  transversely 
  elevated, 
  must 
  

   belong 
  to 
  this 
  group. 
  Blanchard, 
  however, 
  describes 
  it 
  as 
  " 
  breviter 
  ovata," 
  while 
  

   according 
  to 
  Burmeister, 
  who 
  does 
  not 
  mention 
  the 
  form, 
  the 
  anterior 
  tibiae 
  are 
  acute- 
  

   ly 
  3-toothed.

  Texas, 
  Mr. 
  Haldeman. 
  The 
  spaces 
  which 
  represent 
  the 
  usual 
  costae, 
  and 
  the 
  

   suture 
  are 
  marked 
  with 
  a 
  row 
  of 
  smaller 
  punctures. 
  The 
  inferior 
  part 
  of 
  the 
  ungues 
  

   is 
  shorter 
  than 
  the 
  upper, 
  but 
  not 
  so 
  much 
  so 
  as 
  in 
  D. 
  moerens.

  New 
  Braunfels, 
  Texas, 
  Mr. 
  Lindheimer. 
  The 
  punctures 
  between 
  the 
  costa3 
  are 
  

   confused 
  ; 
  the 
  costse 
  are 
  marked 
  with 
  a 
  row 
  of 
  smaller 
  punctures 
  ; 
  the 
  teeth 
  of 
  the 
  

   anterior 
  tibiae 
  are 
  not 
  large, 
  and 
  are 
  more 
  close 
  than 
  usual. 
  The 
  clypeus 
  in 
  one 
  

   specimen 
  is 
  semicircular, 
  but 
  in 
  the 
  other 
  is 
  feebly 
  hemihexagonal. 
  The 
  under 
  part 
  

   of 
  the 
  ungues 
  is 
  hardly 
  shorter 
  than 
  the 
  upper.
