  Mexico." 
  As 
  all 
  the 
  speciuieus 
  seen 
  from 
  these 
  regions 
  which 
  might 
  

   be 
  referred 
  to 
  this 
  species 
  (aud 
  in 
  some 
  instances 
  have 
  been 
  so 
  labeled) 
  

   l)rove 
  to 
  belong 
  to 
  M. 
  paclcardii, 
  I 
  think 
  it 
  probable 
  that 
  some 
  at 
  least 
  of 
  

   these 
  localities 
  may 
  be 
  Avrongly 
  given. 
  The 
  species 
  indeed 
  differs 
  

   but 
  slightly 
  from 
  M. 
  packardii, 
  and 
  maj^ 
  prove 
  to 
  be 
  merely 
  a 
  varietal 
  

   form 
  of 
  it 
  dependent 
  upon 
  station, 
  which 
  in 
  this 
  species 
  is 
  in 
  the 
  dank 
  

   vegetation 
  of 
  river 
  bottoms 
  where 
  M. 
  pacl-ardii 
  occurs 
  but 
  rarely. 
  I 
  

   took 
  a 
  few 
  specimens 
  of 
  the 
  latter, 
  however, 
  in 
  company 
  with 
  the 
  

   former.

  Melanopliis 
  corpulentusBRViiF.R'.,

  infuscated, 
  

   generally 
  in 
  longitudinal

  carinae 
  

   occasionally 
  marked 
  obscurely 
  with 
  flavons, 
  the 
  lateral
