   One 
  male, 
  Texas, 
  Mr. 
  H. 
  Ilaldeman. 
  Remarkable 
  for 
  the 
  characters 
  of 
  the 
  poste- 
  

   rior 
  tibia? 
  and 
  tarsi, 
  though 
  otherwise 
  allied 
  to 
  the 
  preceding. 
  Body 
  oblong, 
  slightly 
  

   narrowed 
  in 
  front, 
  dark 
  reddish 
  brown. 
  Head 
  very 
  densely 
  punctured, 
  clypeus 
  emar- 
  

   ginate, 
  with 
  the 
  margin 
  narrowly 
  reflexed. 
  Thorax 
  more 
  than 
  one-half 
  wider 
  than 
  

   the 
  head, 
  short, 
  coarsely 
  and 
  subconfluently 
  punctured, 
  with 
  various 
  small 
  spaces 
  

   smooth 
  ; 
  punctures 
  smaller 
  and 
  more 
  dense 
  towards 
  the 
  apex, 
  which 
  is 
  broadly 
  foveate 
  

   each 
  side; 
  dorsal 
  line 
  smooth 
  entire; 
  sides 
  hardly 
  serrate, 
  obtusely 
  angulated, 
  slightly 
  

   fimbriate. 
  Scutellum 
  with 
  two 
  groups 
  of 
  punctures. 
  Elytra 
  not 
  shining, 
  rugosely 
  

   punctured, 
  with 
  moderately 
  distinct 
  costae, 
  margin 
  slightly 
  fringed 
  ; 
  pygidium 
  sparsely 
  

   punctured, 
  slightly 
  flattened 
  at 
  the 
  middle. 
  Breast 
  clothed 
  with 
  rather 
  short 
  but 
  

   dense 
  yellow 
  hair. 
  Abdomen 
  punctured 
  ; 
  claws 
  armed 
  with 
  an 
  acute 
  moderate 
  sized 
  

   tooth 
  at 
  the 
  middle. 
  

  

  The 
  male 
  has 
  the 
  club 
  of 
  the 
  antennae 
  as 
  long 
  as 
  the 
  stem 
  ; 
  the 
  abdomen 
  broadly 
  

   concave, 
  the 
  penultimate 
  with 
  a 
  deep 
  posterior 
  medial 
  line, 
  and 
  two 
  rough 
  transverse 
  

   elevations 
  near 
  the 
  anterior 
  margin; 
  the 
  last 
  segment 
  is 
  very 
  broadly 
  excavated 
  ; 
  the 
  

   inner 
  spur 
  of 
  the 
  posterior 
  tibiae 
  is 
  very 
  short, 
  broad, 
  flat, 
  obtuse 
  and 
  concave, 
  the 
  

   outer 
  one 
  is 
  long, 
  flattened, 
  and 
  somewhat 
  acute 
  ; 
  the 
  first 
  joint 
  of 
  the 
  posterior 
  tarsi 
  

   is 
  very 
  much 
  thickened 
  and 
  produced 
  externally. 
  

  

  From 
  the 
  peculiar 
  sexual 
  characters 
  I 
  am 
  inclined 
  to 
  believe 
  that 
  this 
  should 
  be 
  

   separated 
  as 
  a 
  group, 
  but 
  not 
  knowing 
  the 
  female, 
  I 
  cannot 
  indicate 
  any 
  distinctive 
  

   characters 
  applicable 
  to 
  both 
  sexes.

  Nearly 
  of 
  the 
  same 
  form 
  as 
  L. 
  fraterna, 
  but 
  differing 
  by 
  many 
  charac- 
  

   ters. 
  The 
  color 
  is 
  entirely 
  bright 
  reddish-brown, 
  or 
  else 
  blackish-brown 
  with 
  the 
  

   legs 
  and 
  antennae 
  red: 
  the 
  head 
  is 
  sculptured 
  as 
  in 
  L. 
  fraterna: 
  thorax 
  not 
  twice 
  as 
  

   wide 
  as 
  the 
  head, 
  twice 
  as 
  wide 
  as 
  long, 
  narrowed 
  from 
  the 
  base, 
  rounded 
  on 
  the 
  sides.
