  An 
  example 
  of 
  this 
  species 
  was 
  overlooked 
  by 
  me 
  in 
  

   the 
  series 
  of 
  C. 
  aurata 
  in 
  the 
  Salle 
  collection. 
  Mr. 
  

   Smith 
  has 
  since 
  obtained 
  one 
  exactly 
  similar 
  in 
  the 
  

   State 
  of 
  Guerrero.

  One 
  example, 
  which 
  I 
  cannot 
  distinguish 
  from 
  speci- 
  

   mens 
  of 
  C. 
  pilosa 
  from 
  the 
  Eastern 
  States 
  of 
  N. 
  America. 
  

   The 
  species 
  is 
  an 
  addition 
  to 
  the 
  Mexican 
  fauna.

  All 
  the 
  numerous 
  examples 
  taken 
  by 
  Mr. 
  H. 
  H. 
  Smith 
  

   at 
  Omilteme 
  and 
  Xucumanatlan, 
  in 
  Guerrero 
  (alt. 
  7 
  — 
  

   8000 
  ft.), 
  have 
  rather 
  clear 
  reddish 
  antennae 
  and 
  palpi, 
  

   and 
  very 
  many 
  have 
  all 
  the 
  trochanters 
  and 
  tarsi 
  of 
  the 
  

   same 
  colour. 
  The 
  outline 
  of 
  the 
  thorax 
  and 
  strength 
  of 
  

   the 
  punctuation 
  of 
  the 
  upper 
  surface 
  vary, 
  but 
  the 
  latter 
  

   is 
  generally 
  greater 
  than 
  in 
  the 
  typical 
  P. 
  atrata 
  from 
  

   Mexico 
  City. 
  A 
  more 
  universal 
  point 
  of 
  difference 
  is 
  

   the 
  reddish 
  antennge. 
  The 
  variety 
  may 
  be 
  distinguished 
  

   as 
  follows 
  : 
  — 
  

  

  Var. 
  ruficornis. 
  Antennis, 
  palpis 
  et 
  interdum 
  trochantei-ibus 
  

   tarsisque 
  rufis. 
  Long.

  —

  millim. 
  

  

  Another 
  variety 
  of 
  this 
  variable 
  species 
  is 
  distinguished 
  

   by 
  the 
  almost 
  impunctate 
  upper 
  surface 
  :
