  Platte 
  River, 
  Kansas 
  Territory. 
  Nearly 
  allied 
  to 
  the 
  next, 
  but

  head 
  is 
  more 
  

   coarsely 
  and 
  less 
  densely 
  punctured, 
  and 
  the 
  breast 
  is 
  more 
  hairy. 
  The 
  form 
  is 
  a 
  

   little 
  more 
  robust. 
  

  

  In

  male 
  the 
  club 
  of 
  the 
  antennas 
  is 
  as 
  long 
  as 
  the 
  stem, 
  the 
  abdomen 
  is 
  slightly 
  

   flattened 
  longitudinally, 
  and 
  the 
  penultimate 
  segment 
  has 
  a 
  small 
  posterior 
  lunate 
  

   impression 
  at 
  the 
  middle 
  ; 
  the 
  inner 
  spur 
  of 
  the 
  posterior 
  tibia? 
  is 
  Aery 
  small 
  and 
  fixed, 
  

   but 
  the 
  outer 
  one 
  is 
  long 
  and 
  flattened. 
  

  

  In 
  the 
  female 
  the 
  pygidium 
  is 
  less 
  convex 
  and 
  more 
  triangular, 
  and 
  the 
  inner 
  pos- 
  

   terior 
  spur 
  is 
  about 
  one-half 
  as 
  long 
  as 
  the 
  outer

  but 
  more 
  slender.

  Southern 
  States. 
  More 
  robust 
  than 
  the 
  preceding, 
  and 
  approaching 
  in 
  form 
  those 
  

   of 
  the 
  next 
  group. 
  Burmeister 
  describes 
  the 
  male 
  as 
  fuscous 
  on 
  the 
  upper 
  surface 
  ; 
  

   the 
  only 
  two 
  specimens 
  in 
  my 
  collection 
  are 
  males, 
  but 
  are 
  of 
  a 
  reddish 
  yellow 
  color 
  

   both 
  above 
  and 
  beneath 
  ; 
  only 
  the 
  head 
  is 
  dark. 
  

  

  The 
  club 
  of 
  the 
  male 
  is 
  longer 
  than 
  the 
  stem 
  of 
  the 
  antennae 
  ; 
  the 
  three 
  anterior 
  

   segments 
  of 
  the 
  abdomen 
  are 
  longitudinally 
  impressed 
  and 
  the 
  last 
  segment 
  is 
  slightly 
  

   swollen 
  : 
  the 
  pygidium 
  is 
  slightly 
  transverse 
  and 
  strongly 
  punctured 
  ; 
  the 
  inner 
  spur 
  

   of 
  the 
  posterior 
  tibia? 
  is 
  fixed, 
  one-half 
  the 
  length 
  of 
  the 
  outer, 
  which 
  is 
  slender. 
  

  

  Group 
  V. 
  

  

  Containing 
  cylindrical 
  species 
  having 
  the 
  body 
  glabrous 
  above, 
  and 
  beneath 
  only 
  

   slightly 
  pubescent, 
  even 
  on 
  the 
  breast. 
  The 
  head 
  is 
  large, 
  being 
  scarcely 
  one 
  fourth 
  

   narrower 
  than 
  the 
  thorax 
  ; 
  the 
  clypeus 
  is 
  strongly 
  margined, 
  sometimes 
  entire, 
  some- 
  

   times 
  emarginate. 
  The 
  mandibles 
  project 
  beyond 
  the 
  labrum 
  when 
  closed. 
  The 
  last 
  

   joint 
  of 
  the 
  maxillary 
  palpi 
  is 
  variable 
  in 
  form, 
  but 
  is 
  always 
  more 
  or 
  less 
  oval, 
  and 
  

   flattened 
  or 
  impressed 
  along 
  the 
  outer 
  part. 
  The 
  antenna? 
  are 
  10-jointed, 
  with 
  the 
  

   joints 
  3 
  — 
  5 
  connate 
  and 
  indistinct, 
  the 
  sixth 
  and 
  seventh 
  are 
  slightly 
  produced 
  inwards. 
  

   The 
  thorax 
  is 
  remarkably 
  broad, 
  not 
  narrowed 
  behind, 
  nor 
  serrate 
  on 
  the 
  sides. 
  The 
  

   last 
  joint 
  of 
  the 
  abdomen 
  is 
  relatively 
  smaller 
  than 
  in 
  the 
  other 
  groups 
  having 
  the 
  

   inner 
  posterior 
  spur 
  of 
  the 
  male 
  fixed, 
  but 
  in 
  the 
  male 
  is 
  impressed 
  and 
  emarginate.
