  GROUP 
  I. 
  

   This 
  group 
  contains 
  species 
  of 
  an 
  elongate 
  not 
  convex 
  form, 
  and 
  dull 
  sericeous 
  black 
  or 
  

   green 
  colour. 
  The 
  labrum 
  is 
  moderately 
  large, 
  with 
  five 
  anterior 
  teeth, 
  in 
  the 
  males 
  

   the 
  exterior 
  one 
  of 
  these 
  teeth 
  each 
  side 
  is 
  reduced 
  to 
  a 
  slight 
  sinuosity 
  so 
  that 
  the 
  la- 
  

   brum 
  appears 
  tridentate; 
  the 
  lateral 
  angles 
  are 
  rounded. 
  The 
  palpi 
  of 
  the 
  female 
  are 
  

   usually 
  entirely 
  black; 
  the 
  labial 
  palpi 
  of 
  the 
  male 
  are 
  pale, 
  with 
  the 
  last 
  joint 
  black. 
  

   The 
  front 
  is 
  rather 
  flat, 
  glabrous, 
  with 
  only 
  a 
  few 
  very 
  fine 
  stria? 
  each 
  side. 
  The 
  tho- 
  

   rax 
  is 
  trapezoidal, 
  not 
  very 
  convex, 
  with 
  the 
  transverse 
  impressions 
  well 
  defined. 
  The 
  

   elytra 
  are 
  slightly 
  convex, 
  indistinctly 
  punctured 
  except 
  at 
  the 
  base, 
  where 
  the 
  punctures 
  

   are 
  large 
  and 
  scattered: 
  the 
  apex 
  is 
  not 
  serrate, 
  broadly 
  and 
  conjointly 
  rounded 
  in 
  both 
  

   sexes, 
  sutural 
  spine 
  very 
  small 
  : 
  the 
  usual 
  white 
  spots 
  are 
  very 
  small 
  or 
  entirely 
  wanting 
  ; 
  

   the 
  pattern, 
  when 
  most 
  complete, 
  is 
  a 
  humeral 
  spot, 
  an 
  obtusely 
  bent 
  medial 
  band, 
  and 
  

   an 
  apicaldunule. 
  The 
  legs, 
  under 
  part 
  of 
  the 
  thorax, 
  pleura?, 
  and 
  sides 
  of 
  the 
  abdomen 
  

   are 
  clothed 
  not 
  densely 
  with 
  white 
  hair; 
  a 
  few 
  hairs 
  are 
  also 
  seen 
  above 
  on 
  each 
  side 
  of 
  

   the 
  thorax. 
  The 
  three 
  joints 
  of 
  the 
  anterior 
  tarsi 
  of 
  the 
  male 
  are 
  equal 
  in 
  width, 
  and 
  

   moderately 
  dilated.

  One 
  male 
  found 
  by 
  me 
  on 
  the 
  Arkansas 
  River 
  below 
  Bent's 
  Fort. 
  Closely 
  allied 
  to 
  

   the 
  next, 
  and 
  not 
  differing 
  in 
  sculpture; 
  the 
  form 
  of 
  the 
  thorax 
  is 
  however 
  so 
  different, 
  

   that 
  it 
  cannot 
  be 
  considered 
  as 
  a 
  variety 
  : 
  the 
  posterior 
  angles 
  are 
  in 
  the 
  same 
  manner 
  

   rounded, 
  and 
  separated 
  from 
  the 
  base 
  by 
  a 
  slight 
  margin, 
  which 
  causes 
  them 
  to 
  appear 
  

   prominent: 
  the 
  labrum 
  is 
  shorter, 
  and 
  the 
  elytra 
  wider 
  than 
  in 
  C. 
  obsoleta.
