   ly 
  incised 
  at 
  the

  Group 
  II. 
  

  

  Contains 
  species 
  of 
  a 
  robust 
  form 
  and 
  rather 
  large 
  size, 
  having 
  the 
  body 
  glabrous, 
  

   o)' 
  nearly 
  so, 
  above. 
  The 
  head 
  is 
  small, 
  the 
  clypeus 
  broadly 
  margined, 
  and 
  hardly 
  

   or 
  not 
  at 
  all 
  emarginate. 
  The 
  antennas 
  are 
  10-jointed, 
  the 
  mandibles 
  prominent, 
  and 
  

   the 
  last 
  joint 
  of 
  the 
  maxillary 
  palpi 
  slender, 
  not 
  impressed. 
  The 
  thorax 
  is 
  widest 
  at 
  

   the 
  middle, 
  strongly 
  narrowed 
  in 
  front, 
  slightly 
  so 
  behind. 
  The 
  spins 
  of 
  the 
  posterior 
  

   tibiae 
  are 
  free 
  in 
  both 
  sexes, 
  but 
  are 
  very 
  broad 
  and 
  obtuse 
  : 
  the 
  claws 
  are 
  armed 
  near 
  

   the 
  base 
  with 
  a 
  long 
  sharp 
  tooth.

  One 
  female 
  found 
  by 
  Mr. 
  Schott, 
  of 
  the 
  U. 
  S. 
  and 
  Mexican 
  Boundary 
  Commission, 
  

   at 
  Eagle 
  Pass, 
  Texas. 
  

  

  The 
  spurs 
  of 
  the 
  posterior 
  tibiro 
  ai'e 
  elongate, 
  broad 
  and 
  flattened 
  very 
  much 
  as 
  in 
  

   L. 
  lanceolata, 
  and 
  the 
  wings 
  are 
  rudimentary 
  ; 
  but 
  the 
  pygidium 
  is 
  convex 
  and 
  strong- 
  

   ly 
  punctured, 
  and 
  the 
  thorax 
  is 
  formed 
  as 
  in 
  the 
  next 
  species 
  ; 
  for 
  this 
  reason 
  I 
  have 
  

   placed 
  it 
  in 
  the 
  present 
  group.
