  Bates' 
  additions 
  to 
  the 
  

  

  Bmooth 
  in 
  S. 
  multisetosus, 
  punctured 
  like 
  the 
  others 
  (all 
  

   which 
  are 
  punctured 
  nearly 
  to 
  the 
  apex) 
  in 
  S. 
  Triiquii. 
  

   The 
  locality 
  of 
  the 
  latter 
  species 
  is 
  Cuernavaca. 
  

  

  Scythropasus 
  elongatus,

  Two 
  examples, 
  females, 
  of 
  this 
  species 
  have 
  been 
  

   received 
  from 
  Dr. 
  Gaumer, 
  taken 
  at 
  Temax, 
  in 
  North 
  

   Yucatan, 
  and 
  I 
  am 
  indebted 
  to 
  the 
  kindness 
  of 
  M. 
  Salle 
  

   for 
  a 
  male 
  specimen, 
  also 
  from 
  Yucatan. 
  All 
  agree 
  well 
  

   with 
  Chaudoir's 
  description, 
  founded 
  on 
  a 
  unique 
  example 
  

   " 
  from 
  the 
  interior 
  of 
  Mexico."

  an 
  insect 
  from 
  Chontales, 
  

   Nicaragua, 
  is 
  referred 
  to 
  this 
  species, 
  but 
  it 
  differs 
  suffi- 
  

   ciently 
  from 
  the 
  Yucatan 
  species 
  to 
  rank 
  as 
  distinct 
  :

  Body

  and 
  sublinear, 
  as 
  in

  head 
  

   slenderly 
  oval 
  and 
  very 
  gradually 
  narrowed 
  behind 
  the 
  eyes, 
  which 
  

   are 
  much 
  less 
  salient 
  than 
  in 
  the 
  allied 
  genera. 
  Thorax

   quadrate, 
  but 
  a

  the 
  widest

  The 
  elytra 
  have 
  

   smooth, 
  and 
  not, 
  as 
  Lq 
  S. 
  elongatus, 
  finely 
  punctured 
  interstices

   the

  of

  however, 
  the 
  same.
