  The 
  species 
  here 
  described 
  belong 
  to 
  the 
  groups 
  Colobotheides, 
  

   Amphionychides, 
  and 
  iErenieides 
  of 
  Lacordaire 
  and 
  include 
  

   some 
  of 
  the 
  finest 
  species 
  of 
  those 
  groups. 
  They 
  are 
  all 
  

   from 
  South 
  America 
  and 
  the 
  West-Indian 
  islands, 
  and 
  were 
  

   for 
  the 
  most 
  part 
  contained 
  in 
  the 
  collections 
  of 
  Chevrolat 
  and 
  

   Dejean. 
  Where 
  practicable 
  I 
  have 
  retained 
  the 
  manuscript 
  

   names 
  used
