   One 
  specimen 
  found 
  at 
  Fort, 
  Riley 
  by 
  Mr. 
  de 
  \'r*vy. 
  This 
  species 
  lias 
  nearly 
  the 
  

   form 
  of 
  the 
  common 
  varieties 
  of 
  the 
  preceding, 
  but 
  the 
  punctures 
  of 
  the 
  head, 
  espe- 
  

   cially 
  towards 
  the 
  side, 
  support 
  short 
  erect 
  hairs; 
  the 
  punctures 
  of 
  the 
  thorax 
  are 
  

   stronger 
  than 
  usual 
  in 
  that 
  species, 
  and 
  those 
  of 
  the 
  elytra 
  are 
  not 
  dense 
  but 
  strongly 
  

   marked. 
  

  

  The 
  antennae 
  are 
  yellow, 
  and 
  the 
  club 
  of 
  the 
  male 
  is 
  a 
  little 
  longer 
  than 
  the 
  stem; 
  

   the 
  abdomen 
  is 
  broadly 
  impressed 
  longitudinally, 
  and 
  the 
  penultimate 
  segment 
  has 
  an 
  

   obtuse 
  transverse 
  elevation 
  at 
  the 
  middle 
  ; 
  the 
  moveable 
  spur 
  of 
  the 
  posterior 
  tibise 
  is 
  

   more 
  slender 
  than 
  in 
  L. 
  f 
  u 
  s 
  c 
  a; 
  the 
  tooth 
  of 
  the 
  claws 
  is 
  one-half 
  the 
  length 
  of 
  the 
  

   apical 
  portion.

  New 
  York, 
  Mr. 
  Gucx. 
  This 
  species 
  and 
  the 
  preceding 
  are 
  nearly 
  related, 
  but 
  the 
  

   present 
  is 
  more 
  cylindrical 
  in 
  form, 
  with 
  the 
  thorax 
  more 
  rounded 
  on 
  the 
  sides, 
  fringed 
  

   with 
  long 
  hairs, 
  and 
  narrowed 
  only 
  before 
  the 
  middle 
  : 
  the 
  clypeus 
  is 
  also 
  longer, 
  not 
  

   emarginate, 
  and 
  more 
  closely 
  punctured 
  ; 
  and 
  the 
  elytra 
  are 
  finely 
  and 
  densely 
  punc- 
  

   tured. 
  The 
  hairs 
  of 
  the 
  head 
  are 
  sometimes 
  rubbed 
  off, 
  in 
  which 
  case 
  the 
  specimen 
  

   assumes 
  the 
  appearance 
  very 
  nearly 
  of 
  L. 
  sororia, 
  but 
  may 
  be 
  known 
  by 
  the 
  long 
  hairs 
  

   of 
  the 
  sides 
  of 
  the 
  thorax 
  and 
  elytra; 
  the 
  sexual 
  characters 
  are 
  precisely 
  as 
  in 
  the 
  

   preceding.

  margined

  9-jointed

  in 
  form 
  and

  by 
  the 
  outer 
  spur 
  

   of

  less 
  slender,

  by 
  the 
  pygidium
