﻿The 
  following 
  paper 
  comprises 
  all 
  the 
  New-York 
  Insects 
  of 
  the 
  sub-order 
  Hom- 
  

   opUra 
  known 
  to 
  me, 
  except 
  some 
  of 
  the 
  minute 
  species, 
  to 
  determine 
  which 
  re- 
  

   quired 
  further 
  researches. 
  The 
  species 
  and 
  genera 
  that 
  are 
  here 
  presented 
  as 
  new, 
  

   are 
  indicated 
  by 
  an 
  asterisk 
  preceding 
  the 
  scientific 
  name, 
  and 
  a 
  brief 
  description 
  

   of 
  these, 
  embracing 
  their 
  essentia] 
  characters, 
  is 
  added. 
  To 
  the 
  described 
  species 
  

   is 
  appended 
  a 
  reference 
  to 
  the

  the 
  author 
  and 
  the 
  place 
  where 
  the 
  original 
  

   description 
  will 
  be 
  found. 
  

  

  In 
  the 
  generic 
  arrangement 
  of 
  these 
  insects, 
  Amyot 
  and 
  Serville's 
  Hist. 
  Aaf.

   Ins. 
  Hemipteres, 
  Paris, 
  1843, 
  and 
  Westwood-s 
  Synopsis 
  of 
  British 
  Genera, 
  have 
  been~ 
  

   my 
  chief 
  guides. 
  An 
  acknowledgment 
  is 
  due 
  to 
  the 
  Rev. 
  D. 
  Zeigler, 
  of 
  York, 
  Pa., 
  

   for 
  a 
  copy 
  of 
  Gerraar's 
  paper 
  on 
  the 
  genera 
  Clastoptera, 
  &c., 
  in 
  the 
  Zeitschrift 
  f. 
  d. 
  

   Entom.} 
  and 
  to 
  Dr. 
  T. 
  W. 
  Harris, 
  of 
  Harvard 
  University, 
  who 
  has 
  been 
  so 
  kind 
  as 
  to 
  

   place 
  temporarily 
  in 
  my 
  hands 
  his 
  entire 
  collection 
  of 
  Homoptera, 
  including 
  the 
  

   several 
  species 
  named 
  in 
  his 
  Catalogue, 
  and 
  also 
  those 
  magazines 
  and 
  other 
  publi- 
  

   cations 
  which 
  contain 
  all 
  the 
  more 
  important 
  papers 
  of 
  Germar, 
  Spinola 
  and 
  Fallen 
  

   upon 
  this 
  order 
  of 
  insects. 
  I 
  regret 
  that 
  these 
  latter 
  favors 
  were 
  not 
  received 
  in 
  

   season 
  for 
  me 
  to 
  avail 
  myself 
  of 
  them 
  in 
  preparing 
  the 
  following 
  paper, 
  though 
  it 
  

   is 
  not 
  probable 
  they 
  would 
  vary 
  it 
  in 
  any 
  important 
  point 
  from 
  the 
  shape 
  in 
  which 
  

   it 
  is 
  here 
  presented.
