  One 
  male 
  from 
  Georgia. 
  Closely 
  allied 
  to 
  the 
  preceding 
  ; 
  the 
  thorax 
  is 
  finely 
  punc- 
  

   tured, 
  convex, 
  slightly 
  narrowed 
  towards 
  the 
  base. 
  The 
  elytra 
  are 
  finely 
  punctured, 
  

   with 
  the 
  sutural 
  ridge 
  well 
  defined, 
  not 
  wider 
  than 
  usual 
  ; 
  the 
  dorsal 
  costae 
  are 
  very 
  

   faint 
  : 
  the 
  margin 
  is 
  not 
  fringed, 
  and 
  long 
  hairs 
  are 
  seen 
  only 
  towards 
  the 
  base. 
  The 
  

   club 
  of 
  the 
  antennae 
  is 
  as 
  long 
  as 
  the 
  stem, 
  and 
  the 
  abdomen 
  is 
  not 
  impressed. 
  The 
  

   posterior 
  and 
  middle 
  tarsi 
  are 
  imperfect, 
  but 
  the 
  anterior 
  ones 
  are 
  armed 
  only 
  with 
  a 
  

   short 
  acute 
  tooth.

  Texas, 
  at 
  New 
  Braunfels, 
  collected 
  by 
  Mr. 
  Lindheimer. 
  Body 
  oblong, 
  slightly 
  

   ovate, 
  convex; 
  above 
  of 
  a 
  brownish 
  red, 
  with 
  a 
  grayish 
  lustre 
  on 
  the 
  elytra. 
  Head 
  

   densely, 
  thorax 
  finely 
  punctured, 
  clothed 
  not 
  very 
  densely 
  with 
  long 
  soft 
  erect 
  yellow 
  

   hair 
  ; 
  the 
  thorax 
  is 
  short, 
  and 
  is 
  not 
  narrower 
  at 
  the 
  base 
  than 
  at 
  the 
  middle. 
  The 
  

   elytra 
  are 
  finely 
  punctured, 
  not 
  costate, 
  but 
  with 
  the 
  sutural 
  ridge 
  broader 
  and 
  less 
  

   elevated 
  than 
  in 
  the 
  others; 
  the 
  surface 
  is 
  thinly 
  clothed 
  with 
  short 
  yellowish 
  hair, 
  

   with 
  longer 
  hairs 
  intermixed 
  especially 
  towards 
  the 
  base 
  ; 
  the 
  margin 
  is 
  fringed 
  : 
  the 
  

   pygidium 
  is 
  moderately 
  punctured 
  : 
  the 
  breast 
  is 
  covered 
  with 
  tolerably 
  long 
  dense 
  

   hair. 
  

  

  In 
  the 
  male 
  the 
  club 
  of 
  the 
  antenna? 
  is 
  as 
  long 
  as 
  the 
  stem 
  and 
  the 
  abdomen 
  has 
  a 
  

   scarcely 
  perceptible 
  anal 
  impression 
  : 
  the 
  spurs 
  of 
  the 
  posterior 
  tibia? 
  are 
  free 
  in 
  both 
  

   sexes. 
  

  

  a. 
  In 
  one 
  male 
  specimen 
  of 
  a 
  more 
  cylindrical 
  form 
  there 
  is 
  a 
  bifurcating 
  oblique 
  

   elevated 
  line 
  each 
  side 
  of 
  the 
  penultimate 
  ventral 
  segment, 
  but 
  in 
  the 
  other 
  specimens 
  

   I 
  cannot 
  perceive 
  any 
  vestige 
  of 
  such 
  ornament. 
  Subsequent 
  collections 
  may 
  show 
  

   the 
  propriety 
  of 
  regarding 
  it 
  as 
  a 
  separate 
  species, 
  for 
  the 
  sutural 
  ridge 
  is 
  more 
  strong- 
  

   ly 
  marked, 
  and 
  somewhat 
  narrower. 
  I 
  would 
  hesitate 
  at 
  present 
  to 
  give 
  it 
  as 
  distinct, 
  

   as 
  no 
  other 
  difference 
  in 
  sculpture 
  can 
  be 
  perceived. 
  

  

  Group 
  XIII. 
  

  

  Consists 
  of 
  pruinose 
  species, 
  glabrous 
  above, 
  having 
  10-jointed 
  antenna?, 
  and 
  not 
  

   emarginate 
  penultimate 
  ventral 
  segment. 
  The 
  head 
  is 
  comparatively 
  large 
  and 
  the 
  

   clypeus 
  is 
  strongly 
  margined, 
  hardly 
  sinuate 
  in 
  front. 
  The 
  mandibles 
  project 
  strongly 
  ; 
  

   the 
  last 
  joint 
  of 
  the 
  maxillary 
  palpi 
  is 
  slightly 
  oval, 
  not 
  impressed. 
  The 
  thorax 
  is 
  

   rounded 
  on 
  the 
  sides, 
  not 
  narrowed 
  at 
  the 
  base. 
  The 
  breast 
  is 
  tolerably 
  densely 
  

   clothed 
  with 
  long 
  hairs 
  ; 
  the 
  tarsi 
  ai~e 
  long 
  and 
  the 
  ungues 
  are 
  toothed 
  near 
  the 
  base. 
  

  

  In 
  the 
  males 
  the 
  club 
  of 
  the 
  antennae 
  is 
  nearly 
  as 
  long 
  as 
  the 
  stem; 
  the 
  penultimate
