  Many 
  examples,

  nearly 
  all 
  immature. 
  One 
  was 
  

   sent 
  to 
  me 
  by 
  Mr. 
  Flolir 
  with 
  insects 
  from 
  the 
  neigh- 
  

   bourhood 
  of 
  Mexico

  ; 
  I 
  have 
  it 
  so 
  labelled 
  in 
  my 
  

   collection, 
  but 
  strongly 
  suspect 
  it 
  has 
  been 
  referred 
  to 
  

   that 
  locality 
  by 
  mistake.
