  One 
  specimen 
  found 
  by 
  me 
  in 
  Kansas, 
  near 
  Platte 
  River. 
  More 
  robust 
  and 
  less 
  

   cylindrical 
  than 
  the 
  preceding 
  species, 
  with 
  the 
  sides 
  of 
  the 
  thorax 
  less 
  angulated. 
  

   Some 
  of 
  the 
  hairs 
  about 
  the 
  base 
  of 
  the 
  thorax 
  arise 
  from 
  the 
  disc, 
  and 
  the 
  hairs 
  near 
  

   the 
  base 
  of 
  the 
  elytra 
  are 
  longer 
  than 
  in 
  the 
  other 
  species, 
  and 
  the 
  punctures 
  behind 
  

   the 
  middle 
  are 
  almost 
  without 
  hairs. 
  The 
  spurs 
  of 
  the 
  posterior 
  tibiee 
  are 
  as 
  in 
  the 
  

   preceding.

  This 
  species, 
  though 
  having 
  all 
  the 
  external 
  appearance 
  of 
  

  

  the 
  others, 
  by 
  its 
  characters 
  approaches 
  so 
  near 
  to 
  Lachnosterna 
  as 
  to 
  suggest 
  a 
  doubt 
  

  

  whether 
  the 
  two 
  genera 
  should 
  properly 
  remain 
  distinct.

  From
