  and 
  Mexican 
  Boundary 
  Commission, 
  on 
  

   the 
  journey 
  from 
  Laredo 
  to 
  Ringgold 
  Barracks. 
  Body 
  oblong 
  cylindrical, 
  convex, 
  

   uniform 
  reddish, 
  with 
  a 
  pruinose 
  lustre. 
  Head 
  large, 
  closely 
  punctured, 
  clypeus 
  

   scarcely 
  sinuate 
  in 
  front, 
  but 
  strongly 
  margined. 
  Thorax 
  more 
  than 
  one-third 
  wider 
  

   than 
  the 
  head, 
  finely 
  and 
  closely 
  punctured, 
  sides 
  rounded 
  subserrate, 
  sparsely

   Elytra 
  more 
  strongly 
  punctured, 
  with 
  very 
  short 
  procumbent 
  hairs 
  in 
  each 
  puncture, 
  

   sutural

  Kansas, 
  near 
  the 
  Rocky 
  Mountains. 
  Agrees 
  with 
  the 
  preceding 
  in 
  sculpture, 
  but 
  

   is 
  smaller 
  and 
  somewhat 
  more 
  robust, 
  the 
  surface 
  is 
  less 
  pruinose, 
  the 
  punctures 
  of 
  

   the 
  elytra 
  support 
  hairs 
  so 
  much 
  smaller 
  that 
  they 
  are 
  hardly 
  visible, 
  and 
  the 
  sub- 
  

   marginal 
  costa 
  can 
  hardly 
  be 
  seen. 
  The 
  sexual 
  characters 
  are 
  precisely 
  as 
  in 
  the 
  

   preceding. 
  

  

  More 
  full 
  series 
  may 
  show 
  the 
  propriety 
  of 
  regarding 
  this 
  as 
  a 
  race 
  of 
  the 
  preceding 
  

   species, 
  but 
  at 
  present 
  it 
  seems 
  sufficiently 
  distinct 
  to 
  entitle 
  it 
  to 
  a 
  separate 
  name. 
  

  

  Group 
  XIV. 
  

  

  I 
  have 
  placed 
  in 
  this 
  group 
  a 
  single 
  species 
  having 
  the 
  appearance 
  of 
  those 
  of 
  the 
  

   next 
  group, 
  but 
  differing 
  by 
  the 
  more 
  robust 
  form, 
  and 
  by 
  the 
  mandibles 
  being 
  visible 
  at 
  

   the 
  tip. 
  The 
  head 
  is 
  small 
  and 
  hairy, 
  the 
  clypeus 
  deeply 
  concave 
  and 
  rounded 
  ; 
  the 
  

   last 
  joint 
  of 
  the 
  maxillary 
  palpi 
  is 
  hardly 
  oval, 
  and 
  not 
  impressed; 
  the 
  mandibles 
  

   are 
  visible 
  and 
  tolerably 
  prominent. 
  The 
  antenna? 
  are 
  10-jointed. 
  The 
  thorax 
  is 
  

   hairy 
  and 
  not 
  narrowed 
  at 
  the 
  base. 
  The 
  last 
  ventral 
  segment 
  is 
  very 
  short, 
  as 
  in 
  

   the 
  two 
  preceding 
  groups, 
  and 
  the 
  penultimate 
  of 
  the 
  male 
  is 
  not 
  impressed. 
  The 
  

   claws 
  are 
  armed 
  with 
  a 
  small 
  tooth 
  at 
  the 
  middle.
