  Found 
  in 
  sandy 
  places, 
  in 
  various 
  parts 
  of 
  the 
  Eastern, 
  Middle 
  and 
  Southern 
  States. 
  

   The 
  black 
  race 
  does 
  not 
  occur 
  at 
  the 
  same 
  localities 
  with 
  the 
  green 
  one, 
  but 
  on 
  close 
  

   comparison, 
  nothing 
  of 
  specific 
  character 
  can 
  be 
  found 
  to 
  separate 
  them. 
  The 
  form 
  a 
  is 
  

   found 
  in 
  Georgia, 
  Alabama 
  and 
  Florida, 
  and 
  is 
  usually 
  of 
  a 
  more 
  obscure 
  green 
  than 
  the 
  

   type.

  Valley 
  of 
  Platte 
  River, 
  on 
  sand 
  hills 
  in 
  June; 
  not 
  abundant. 
  The 
  colour 
  of 
  the 
  head 
  

   and 
  thorax 
  varies 
  from 
  full 
  green 
  to 
  blue 
  : 
  the 
  sides 
  of 
  the 
  latter 
  are 
  less 
  rounded 
  in 
  the 
  

   male 
  than 
  in 
  the 
  female. 
  The 
  colour 
  of 
  the 
  elytra 
  also 
  varies 
  from 
  coppery 
  to 
  brassy.

  One 
  pair 
  found 
  near 
  Bent's 
  Fort 
  on 
  the 
  Arkansas 
  River. 
  The 
  elytra 
  of 
  this 
  species 
  

   are 
  more 
  elongated 
  than 
  in 
  the 
  others 
  of 
  this 
  group, 
  and 
  the 
  sexual 
  characters 
  are 
  differ- 
  

   ent 
  ; 
  yet 
  by 
  the 
  indistinct 
  punctures 
  of 
  the 
  elytra, 
  as 
  well 
  as 
  by 
  the 
  absence 
  of 
  serrature 
  

   and 
  sutural 
  spine, 
  it 
  seems 
  to 
  be 
  here 
  properly 
  appended. 
  It 
  is 
  a 
  stouter 
  species 
  than 
  C. 
  

   punctulata, 
  which 
  it 
  at 
  first 
  sight 
  seems 
  to 
  resemble. 
  

  

  group 
  v. 
  

  

  Labrum 
  moderate, 
  advanced 
  in 
  the 
  middle, 
  strongly 
  tridentate. 
  Head 
  and 
  thorax 
  

   glabrous, 
  finely 
  rugose, 
  the 
  former 
  finely 
  striate 
  between 
  the 
  eyes, 
  the 
  latter 
  convex 
  and 
  

   strongly 
  impressed. 
  Palpi 
  entirely 
  black. 
  Elytra 
  strongly 
  punctured, 
  broadly 
  rounded, 
  

   and 
  but 
  very 
  obsoletely 
  serrate 
  at 
  tip, 
  sutural 
  spine 
  distinct: 
  spots 
  small, 
  the 
  anterior 
  

   ones 
  in 
  one 
  species 
  hardly 
  ever 
  visible. 
  Body 
  beneath 
  very 
  sparsety 
  pilose. 
  

  

  Differs 
  from 
  the 
  next 
  group 
  by 
  the 
  bald 
  front, 
  and 
  slightly 
  serrate 
  tips 
  of 
  the 
  elytra.
