  for 
  on 
  beets. 
  It 
  is 
  at 
  present, 
  in 
  fact, 
  our 
  commonest 
  beet 
  leaf-louse 
  in 
  

   Illinois. 
  Though 
  not 
  especially 
  abundant, 
  it 
  occurs 
  in 
  small 
  colonies 
  

   on 
  the 
  under 
  side 
  of 
  the 
  leaves 
  in 
  the 
  latter 
  part 
  of 
  June 
  and 
  in 
  July, 
  

   being 
  most 
  numerous 
  about 
  the 
  end 
  of 
  June. 
  The 
  first 
  win'ged 
  individuals 
  

   were 
  noted 
  July 
  5th. 
  It 
  is 
  a 
  green 
  aphis, 
  with 
  but 
  little 
  dark 
  coloring 
  in 
  

   the 
  wingless 
  female. 
  The 
  winged 
  female 
  has 
  the 
  thorax 
  and 
  antennae 
  

   black 
  and 
  a 
  large 
  dark 
  patch 
  on 
  the 
  abdomen 
  between 
  the 
  honey-tubes. 
  

   The 
  species 
  is 
  also 
  recorded 
  from 
  Amarantus 
  (Williams) 
  and 
  Malva 
  ro- 
  

   tundifolia 
  QEstlund), 
  and 
  we 
  have 
  collected 
  it 
  in 
  abundance 
  on 
  corn. 
  

  

  Nectarophora 
  erigeronensis 
  Thos.? 
  

   Specimens 
  were 
  taken 
  in 
  sweepings 
  from 
  sugar 
  beets 
  July 
  13th, 
  14th, 
  

   and 
  26th 
  in 
  the 
  vicinity 
  of 
  Pekin, 
  111., 
  and 
  on 
  the 
  University 
  farm 
  (on 
  the 
  

   first 
  date 
  mostly 
  wingless 
  ) 
  which 
  agree 
  fairly 
  well 
  with 
  the 
  descriptions 
  of 
  

   erigeroftensis 
  except 
  as 
  to 
  the 
  tibiae. 
  These 
  are 
  usually 
  pale 
  with 
  black 
  

   tips, 
  and 
  not 
  entirely 
  black 
  as 
  stated 
  for 
  erigeronensis. 
  The 
  honey- 
  

   tubes 
  are 
  either 
  entirely 
  dark 
  or 
  with 
  the 
  basal 
  portion 
  pale. 
  The 
  an- 
  

   tennae 
  are 
  dark 
  except 
  at 
  base, 
  the 
  femora 
  with 
  the 
  apical 
  part, 
  or 
  even 
  

   more 
  than 
  half 
  the 
  length, 
  black. 
  

  

  Nectarophora 
  pisi 
  Kalt. 
  

   The 
  "green 
  dolphin 
  " 
  is 
  a 
  rather 
  common 
  garden 
  pest 
  in 
  the 
  United 
  

   States. 
  Its 
  body 
  and 
  appendages 
  are 
  almost 
  entirely 
  green. 
  It 
  infests 
  

   principally 
  plants 
  of 
  the 
  pea 
  family 
  {Leguminosa;), 
  especially 
  the 
  garden 
  

   pea, 
  sweet 
  pea, 
  and 
  clover, 
  but 
  has 
  also 
  been 
  taken 
  in 
  the 
  pupal 
  and 
  

   winged 
  stages 
  on 
  beets 
  in 
  Nebraska, 
  and 
  in 
  Europe 
  on 
  shepherd's-purse, 
  

   nettles, 
  and 
  Spircza. 
  In 
  Illinois 
  it 
  occurs 
  mostly 
  about 
  the 
  end 
  of 
  May. 
  

  

  THE 
  FLAT 
  AS 
  OR 
  LANTERN-FLIES.

  Mealy 
  Flata 
  (^Ormenis 
  pruinosa

   The 
  Green 
  Flata 
  (^Chiorochroa 
  conica 
  Say). 
  

   Although 
  these 
  odd 
  looking 
  insects, 
  closely 
  related 
  to 
  the 
  leaf- 
  

   hoppers, 
  are 
  common 
  and 
  injurious 
  in 
  Illinois 
  and 
  elsewhere, 
  they 
  have 
  

   not 
  received 
  the 
  attention 
  from 
  economic 
  entomologists 
  that 
  they 
  deserve. 
  

   They 
  are 
  from 
  a 
  quarter 
  to 
  half 
  an 
  inch 
  long, 
  with 
  broad 
  flat 
  wings, 
  

   held 
  vertically 
  and 
  meeting 
  behind 
  the 
  body. 
  As 
  the 
  insect 
  is 
  broad 
  in 
  

   front, 
  the 
  general 
  form 
  when 
  at 
  rest, 
  seen 
  from 
  above, 
  is 
  that 
  of 
  a 
  wedge. 
  

   The 
  young 
  are 
  covered 
  with 
  a 
  white 
  woolly 
  excretion. 
  Like 
  some 
  plant- 
  

   lice 
  they 
  collect 
  in 
  patches 
  on 
  the 
  under 
  side 
  of 
  leaves 
  or 
  on 
  their 
  stems, 
  

   and 
  do 
  their 
  injury 
  by 
  sucking 
  out 
  the 
  sap. 
  These 
  young 
  are 
  rather 
  

   short 
  and 
  blunt 
  at 
  the 
  ends, 
  very 
  broad 
  across 
  the 
  wing-pads, 
  and 
  pale 
  

   greenish 
  beneath 
  the 
  woolly 
  coating. 
  This 
  latter 
  rubs 
  off 
  easily, 
  but 
  

   those 
  which 
  have 
  lost 
  it 
  reproduce 
  it 
  within 
  a 
  few 
  days.
