  Most 
  of 
  the 
  eggs 
  hatch 
  in 
  May, 
  the 
  larvae 
  becoming 
  common 
  in 
  early 
  

   summer. 
  In 
  June 
  these 
  begin 
  to 
  transform 
  to 
  adults. 
  We 
  have 
  taken 
  

   the 
  latter 
  in 
  large 
  numbers 
  at 
  electric 
  lights 
  in 
  the 
  first 
  half 
  of 
  June, 
  and 
  

   found 
  them 
  laying 
  eggs 
  for 
  a 
  second 
  brood 
  July 
  i6th 
  and 
  22d. 
  The 
  eggs 
  

   were 
  placed 
  in 
  the 
  pith 
  and 
  vi^oody 
  tissue 
  of 
  bulrushes 
  {Scirpus 
  fluviatilis) 
  

   and 
  in 
  the 
  substance 
  of 
  the 
  leaf 
  sheath 
  and 
  blades. 
  June 
  23d 
  to 
  25th 
  

   these 
  insects 
  were 
  noted 
  as 
  common 
  on 
  corn, 
  and 
  one 
  was 
  seen 
  in 
  the 
  

   act 
  of 
  laying 
  its 
  eggs 
  in 
  a 
  corn 
  leaf. 
  The 
  second 
  brood 
  of 
  larvae 
  appear 
  

   in 
  August 
  and 
  September, 
  transforming 
  in 
  fall 
  to 
  adults. 
  These, 
  again, 
  

   gather 
  in 
  low 
  grounds, 
  and 
  most 
  of 
  them 
  lay 
  eggs 
  and 
  die 
  before 
  cold 
  

   weather. 
  

  

  The 
  species 
  abounds 
  especially 
  on 
  reedy 
  grasses 
  of 
  the 
  salt 
  marshes 
  

   of 
  the 
  Atlantic 
  coast. 
  In 
  Kentucky 
  it 
  suffered 
  severely 
  in 
  late 
  July 
  and 
  

   early 
  August 
  from 
  a 
  parasitic 
  fungus, 
  Empusa 
  grylli. 
  It 
  is 
  probable 
  that 
  

   the 
  burning 
  of 
  slough 
  grass 
  and 
  the 
  like 
  vegetation 
  in 
  winter 
  would 
  be 
  

   a 
  useful 
  measure 
  of 
  protection 
  against 
  injury 
  by 
  this 
  insect. 
  

  

  Gypona 
  8-lineata 
  Say. 
  

  

  This 
  leaf-hopper, 
  fairly 
  common 
  in 
  Illinois, 
  occurs 
  over 
  the 
  eastern 
  

   United 
  States 
  from 
  Canada 
  to 
  Texas. 
  It 
  has 
  occasionally 
  appeared 
  in 
  

   our 
  sugar-beet 
  collections 
  from 
  the 
  Experiment 
  Station 
  farm. 
  Osborn 
  

   says 
  that 
  it 
  does 
  not 
  seem 
  to 
  be 
  confined 
  to 
  any 
  particular 
  food 
  plant, 
  

   but 
  may 
  be 
  found 
  almost 
  everywhere, 
  preferring 
  rank 
  growths 
  in 
  shaded 
  

   situations. 
  The 
  color 
  deepens 
  and 
  changes 
  with 
  the 
  season's 
  advance, 
  

   most 
  of 
  the 
  first 
  brood 
  and 
  the 
  earliest 
  of 
  the 
  second 
  being 
  light 
  green 
  

   with 
  indefinite 
  yellow 
  lines 
  and 
  weak 
  elytral 
  reticulations; 
  and 
  the 
  last 
  

   of 
  the 
  first 
  and 
  nearly 
  all 
  of 
  the 
  second, 
  dark 
  green, 
  with 
  strongly 
  reticu- 
  

   late 
  elytra. 
  In 
  September 
  and 
  October 
  the 
  lines 
  tend 
  to 
  become 
  red, 
  

   and 
  females 
  may 
  be 
  found 
  almost 
  wholly 
  scarlet 
  dorsally.

   Although 
  our 
  other 
  species 
  of 
  Gypona 
  are 
  apparently 
  one-brooded, 
  this 
  

   has 
  two 
  broods 
  in 
  a 
  year. 
  The 
  adults 
  of 
  the 
  first 
  brood 
  appear 
  in 
  late 
  

   June 
  and 
  in 
  July, 
  and 
  those 
  of 
  the 
  second 
  in 
  fall. 
  They 
  are 
  most 
  abun- 
  

   dant 
  with 
  us 
  about 
  the 
  end 
  of 
  June, 
  when 
  they 
  have 
  been 
  taken 
  in 
  large 
  

   numbers 
  at 
  electric 
  lights. 
  The 
  nymphal 
  stages 
  of 
  these 
  broods 
  are 
  

   commonest 
  in 
  June, 
  and 
  in 
  August 
  and 
  September, 
  respectively. 
  There 
  

   is 
  no 
  record 
  of 
  the 
  capture 
  of 
  hibernating 
  adults, 
  and 
  the 
  species 
  proba- 
  

   bly 
  winters 
  in 
  the 
  egg. 
  The 
  head 
  is 
  noticeably 
  wide, 
  broadly 
  rounded 
  

   in 
  front, 
  and 
  slightly 
  shovel 
  shaped. 
  The 
  front 
  of 
  the 
  head 
  in 
  the 
  larva 
  

   is 
  more 
  elongate 
  and 
  very 
  thin, 
  the 
  sides 
  parallel 
  in 
  front 
  of 
  the 
  eyes, 
  

   and 
  the 
  tip 
  broadly 
  rounded. 
  

  

  Platymetopius 
  acutus 
  Say. 
  

  

  This 
  leaf-hopper 
  is 
  notably 
  different 
  from 
  the 
  other 
  small 
  beet- 
  

   species 
  in 
  the 
  pointed 
  elongate 
  head 
  which 
  has 
  the 
  form 
  of 
  an 
  equal-
