  Mr. 
  H. 
  W. 
  Bates' 
  additions 
  to 
  the 
  

  

  Calosoma 
  anthracinum, 
  Dej. 
  

   Mr. 
  Smith 
  captured 
  several 
  examples 
  of 
  this 
  species 
  

   at 
  Amula, 
  in 
  Guerrero. 
  

  

  Calosoma 
  Icevigatum, 
  Chaud. 
  

   Numerous 
  specimens 
  of 
  this 
  species 
  have 
  been 
  received 
  

   from 
  Real 
  del 
  Monte 
  (Pachuca), 
  from 
  Mr. 
  Eichardson. 
  

  

  Calosoma 
  costipenne, 
  Chaud. 
  

   Mr. 
  Richardson 
  captured 
  two 
  examples 
  of 
  this 
  insect 
  

   at 
  Rio 
  Frio. 
  

  

  Calososoma 
  atrovirens, 
  Chaud. 
  

  

  The 
  precise 
  locality 
  of 
  this 
  species 
  was 
  unknown 
  to 
  

   the 
  describer. 
  Herr 
  Hoge 
  obtained 
  it 
  at 
  Tula, 
  in 
  

   Hidalgo. 
  Only 
  two 
  of 
  his 
  examples 
  were 
  coloured 
  

   green, 
  with 
  the 
  disk 
  of 
  the 
  thorax 
  black, 
  many 
  others 
  

   showing 
  a 
  green 
  or 
  bluish 
  tinge 
  only 
  on 
  the 
  borders 
  of 
  

   the 
  elytra, 
  and 
  on 
  the 
  sides 
  of 
  the 
  prosternum 
  ; 
  this 
  is 
  

   the 
  var. 
  ohscurum 
  of 
  Gehin's 
  Cat. 
  des 
  Carab. 
  (1885), 
  

   p. 
  65. 
  Others 
  from 
  the 
  same 
  locality 
  are 
  entirely 
  black, 
  

   and 
  are 
  so 
  similar 
  to 
  the 
  typical 
  form 
  of 
  C. 
  Icsve, 
  that 
  I 
  

   fail 
  to 
  detect 
  any 
  definite 
  character 
  by 
  which 
  to 
  separate 
  

   them. 
  The 
  only 
  differences 
  are 
  the 
  oily 
  or 
  silky 
  gloss 
  

   of 
  the 
  surface 
  (C. 
  Iceve 
  being 
  almost 
  always 
  polished 
  

   black), 
  and 
  the 
  more 
  broadly 
  rounded 
  sides 
  of 
  the 
  thorax 
  

   preceding 
  the 
  hind 
  angles 
  ; 
  some 
  few 
  examples 
  of 
  C. 
  Iceve, 
  

   however, 
  have 
  precisely 
  the 
  same 
  outline 
  of 
  thorax.

  Hah. 
  Omilteme, 
  in 
  Guerrero, 
  8000 
  ft. 
  (H. 
  H. 
  Smith). 
  

  

  This 
  distinct 
  species 
  has 
  the 
  slender 
  form 
  and 
  rela- 
  

   tively 
  small, 
  cordate 
  thorax, 
  of 
  C. 
  blajjto'ides. 
  The 
  

   thorax 
  is 
  smooth, 
  silky-opaque, 
  as 
  in 
  that 
  species, 
  but 
  

   the 
  head 
  differs 
  in 
  having 
  a 
  cluster 
  of 
  large 
  punctures 
  

   on 
  each 
  side 
  of 
  the 
  forehead, 
  and 
  the 
  mandibles 
  are
