  Dr.

  A. 
  Hammond 
  ; 
  found 
  according 
  to 
  Blanchard 
  in 
  Georgia, 
  

   and 
  Burmeister 
  in 
  S. 
  Carolina. 
  Differs 
  from 
  the 
  next 
  two 
  species 
  by 
  the 
  less 
  rounded 
  

   sides 
  of 
  the 
  thorax, 
  and 
  the 
  more 
  narrowly 
  margined 
  clypeus 
  ; 
  the 
  latter 
  is 
  rounded 
  

   in 
  the 
  arc 
  of 
  a 
  circle. 
  The 
  punctures 
  of 
  the 
  costse 
  of 
  the 
  elytra 
  are 
  somewhat 
  irregu- 
  

   lar 
  ; 
  the 
  teeth 
  of 
  the 
  anterior 
  tibiae 
  are 
  obtuse, 
  and 
  the 
  two 
  lower 
  ones 
  are 
  nearer.

  A 
  common 
  species 
  from 
  New 
  York 
  to 
  Texas, 
  and 
  Kansas. 
  The 
  head 
  is 
  always 
  

   slightly 
  hemihexagonal 
  ; 
  the 
  under 
  part 
  of 
  the 
  claws 
  is 
  not' 
  shorter 
  than 
  the 
  upper 
  

   portion. 
  The 
  punctures 
  between 
  the 
  costse 
  are 
  confused, 
  and 
  the 
  costse 
  are 
  marked 
  

   with 
  a 
  row 
  of 
  smaller 
  punctures. 
  

  

  The 
  species 
  described 
  by 
  Mr. 
  Blanchard 
  as 
  Say's 
  is 
  something 
  quite 
  different.

  Texas, 
  two 
  specimens, 
  Mr. 
  Haldeman. 
  So 
  similar 
  to 
  the 
  preceding, 
  that 
  it 
  might 
  

   readily 
  be 
  confounded 
  with 
  it. 
  On 
  comparison, 
  however, 
  several 
  differences 
  may 
  be 
  

   found 
  : 
  the 
  thorax 
  is 
  not 
  so 
  short, 
  and 
  the 
  posterior 
  angles 
  are 
  less 
  obtuse 
  ; 
  the 
  clypeus 
  

   is 
  rounded 
  in 
  an 
  arc 
  of 
  a 
  circle, 
  and 
  more 
  strongly 
  margined 
  ; 
  the 
  upper 
  tooth 
  of 
  the 
  

   anterior 
  tibia) 
  is 
  almost 
  entirely 
  obliterated.

  One 
  specimen, 
  Kansas. 
  The 
  costse 
  of 
  the 
  elytra 
  are 
  without 
  punctures, 
  or 
  with 
  

   only 
  a 
  very 
  few 
  small 
  ones. 
  The 
  upper 
  tooth 
  of 
  the 
  anterior 
  tibiae 
  is 
  acute 
  and 
  dis- 
  

   tant 
  from 
  the 
  others.
