  A 
  number 
  of 
  specimens 
  in 
  the 
  material 
  at 
  hand 
  

   agree 
  with 
  the 
  description 
  of 
  this 
  species. 
  These 
  specimens 
  come 
  

   from 
  Cordoba, 
  Vera 
  Cruz, 
  Mexico, 
  collected 
  April 
  10, 
  11,

  and

  Fenyes. 
  

  

  The 
  two 
  genera 
  described 
  as 
  new 
  in 
  this 
  paper 
  differ 
  from 
  typical 
  

   Osorius 
  as 
  exemplified 
  in 
  Osorius 
  latipes

  the 
  absence 
  

   of 
  a 
  median 
  tubercular 
  swelling 
  on 
  the 
  prosternum. 
  This 
  tubercula- 
  

   tion 
  is 
  present 
  in 
  all 
  the 
  species 
  known 
  to 
  me 
  from 
  specimens. 
  

   Oryssomma 
  and 
  Mimogonus 
  also 
  differ 
  from 
  Osorius 
  in 
  the 
  approxi- 
  

   mation 
  of 
  the 
  eye 
  and 
  the 
  antenna 
  and 
  in 
  the 
  stout 
  and 
  parallel 
  first 
  

   antennal 
  joint.
