  This 
  species 
  was 
  discovered 
  by 
  Mr. 
  A. 
  Salle 
  near 
  New 
  Orleans, 
  and 
  kindly 
  given 
  me 
  

   by 
  Mr. 
  Guex. 
  It 
  agrees 
  so 
  closely 
  with 
  the 
  descriptions 
  and 
  figures 
  of 
  A. 
  fuscipes 
  Fabr., 
  

   that 
  I 
  supposed 
  it 
  to 
  be 
  that 
  species, 
  imported 
  accidentally 
  from 
  the 
  East 
  Indies. 
  Re- 
  

   cently, 
  however, 
  Mr. 
  Schott, 
  of 
  the 
  Mexican 
  Boundary 
  Commission, 
  has 
  found 
  it 
  in 
  abun- 
  

   dance 
  on 
  the 
  lower 
  Rio 
  Grande, 
  at 
  Eagle 
  Pass. 
  Between 
  the 
  punctures 
  of 
  the 
  elytra 
  may 
  

   be 
  perceived 
  small 
  transverse 
  rugosities: 
  the 
  smooth 
  dorsal 
  line 
  of 
  the 
  thorax 
  is 
  very 
  in- 
  

   distinct, 
  and 
  is 
  visible 
  only 
  near 
  the 
  base; 
  the 
  basal 
  tubercle 
  is 
  large 
  and 
  almost 
  reclivate.

  I 
  have 
  named 
  this 
  fine 
  species 
  after 
  Mr. 
  Schott, 
  as 
  a 
  slight 
  tribute 
  to 
  the 
  scientific 
  zeal 
  

   displayed 
  while 
  attached 
  to 
  the 
  Boundary 
  Commission 
  under 
  Majors 
  Graham 
  and 
  Emory; 
  

   a 
  single 
  specimen 
  was 
  procured 
  on 
  the 
  lower 
  Rio 
  Grande. 
  The 
  sculpture 
  is 
  as 
  in 
  the 
  

   preceding, 
  from 
  which 
  this 
  species 
  differs 
  in 
  the 
  form 
  of 
  the 
  thorax. 
  It 
  exactly 
  resembles 
  

   in 
  appearance 
  the 
  Egyptian 
  A. 
  notodonta 
  Lair.

  For 
  a 
  specimen 
  found 
  in 
  Louisiana, 
  I 
  am 
  indebted 
  to 
  Mr. 
  Guex. 
  The 
  little 
  tubercle 
  of 
  

   the 
  middle 
  of 
  the 
  base 
  of 
  the 
  thorax 
  is 
  quite 
  prominent. 
  

  

  Ai'hanohius 
  Esch. 
  (emend.) 
  

   This 
  genus 
  should 
  be 
  restricted 
  to 
  those 
  species 
  having 
  the 
  last 
  joint 
  of 
  the 
  antenna} 
  

   deeply 
  constricted, 
  the 
  front 
  slightly 
  concave 
  and 
  not 
  margined 
  in 
  front; 
  the 
  mesosternum 
  

   prominent; 
  the 
  plates 
  of 
  the 
  posterior 
  coxa; 
  somewhat 
  suddenly 
  slightly 
  dilated, 
  and 
  emar- 
  

   ginate 
  posteriorly, 
  and 
  the 
  internal 
  tooth 
  sharp, 
  and 
  moderately 
  large: 
  the 
  tarsi 
  are 
  some- 
  

   what 
  inflated 
  beneath, 
  and 
  very 
  densely 
  pubescent, 
  (being 
  in 
  this 
  respect 
  precisely 
  as 
  in 
  

   Agrypnus 
  fuscipes.) 
  The 
  first 
  joint 
  of 
  the 
  antennae 
  is 
  moderately 
  elongated, 
  the 
  second 
  

   and 
  third 
  small, 
  the 
  fourth 
  and 
  following 
  strongly 
  triangular, 
  and 
  equal: 
  the 
  suture 
  of 
  the 
  

   prosternum 
  is 
  bent 
  outwards 
  posteriorly, 
  and 
  is 
  very 
  deeply 
  marked: 
  the 
  first 
  joint 
  of 
  the 
  

   tarsi 
  is 
  hardly 
  as 
  long 
  as 
  the 
  second 
  and 
  third 
  united: 
  the 
  base 
  of 
  the 
  thorax 
  has 
  a 
  slight 
  

   elevation 
  in 
  front 
  of 
  the 
  scutellum, 
  but 
  it 
  is 
  by 
  no 
  means 
  obvious: 
  the 
  posterior 
  angles 
  

   have 
  a 
  short 
  carina: 
  there 
  are 
  no 
  apparent 
  basal 
  fissures.
