  Pergande 
  left 
  the 
  following 
  color 
  notes: 
  "The 
  winged 
  form 
  is 
  

   either 
  yellowish 
  or 
  yellowish 
  green. 
  Head, 
  antennae, 
  band 
  across 
  

   prothorax, 
  thoracic 
  lobes 
  and 
  sternal 
  plate, 
  apex 
  of 
  femora, 
  tibiae 
  

   and 
  tarsi, 
  lateral 
  spot 
  in 
  front 
  of 
  wings, 
  3 
  lateral 
  spots 
  in 
  front 
  of 
  

   nectaries 
  black; 
  the 
  lateral 
  edge 
  of 
  this 
  spot 
  is 
  more 
  or 
  less 
  sharply 
  

   3-dentate; 
  the 
  anterior 
  angle 
  is 
  formed 
  of 
  two 
  very 
  fine 
  black 
  and 
  

   curved 
  lines, 
  uniting 
  at 
  the 
  ends 
  in 
  a 
  large 
  black 
  spot; 
  the 
  other 
  

   two 
  angles 
  are 
  formed 
  of 
  3 
  broad, 
  and 
  shorter 
  black 
  bands, 
  with 
  the 
  

   last 
  band 
  sometimes 
  very 
  fine 
  and 
  barely 
  visible 
  except 
  at 
  the 
  angle; 
  

   the 
  space 
  between 
  these 
  lines 
  and 
  bands 
  is 
  of 
  the 
  color 
  of 
  the 
  abdo- 
  

   men, 
  though 
  sometimes 
  they 
  may 
  be 
  confluent 
  so 
  as 
  to 
  form 
  a 
  com- 
  

   plete 
  black 
  spot; 
  nectaries 
  pale 
  dusky, 
  tail 
  yellow; 
  subcosta 
  yellow- 
  

   ish, 
  the 
  stigma 
  pale 
  dusky." 
  

  

  I 
  have 
  received 
  a 
  single 
  alate 
  specimen 
  from 
  Dr. 
  J. 
  T. 
  Potgieter 
  

   taken 
  on 
  sycamore 
  at 
  Columbus, 
  Ohio, 
  October 
  6, 
  1922. 
  I 
  can 
  see 
  

   no 
  specific 
  difference 
  between 
  it 
  and 
  the 
  form 
  described 
  above 
  from 
  

   currant. 
  It 
  is 
  probable 
  that 
  it 
  was 
  simply 
  resting 
  on 
  the 
  sycamore. 
  

  

  Alate 
  male. 
  — 
  Antennae 
  longer 
  than

  dark 
  colored, 
  imbricated, 
  

   III, 
  IV. 
  and 
  V

  numerous 
  tuberculate 
  sensoria;

   than

  of 
  segments. 
  Antennal 
  tubercles 
  very 
  small. 
  Beak 
  

   short, 
  about 
  reaching

  coxae. 
  A 
  small 
  lateral 
  prothoracic 
  

   tubercle 
  with 
  spine 
  in 
  front 
  of 
  it. 
  Abdominal 
  segments 
  with 
  a 
  dark 
  

   area 
  and 
  several 
  smaller 
  ones 
  on 
  dorsum 
  of 
  abdomen.

   short, 
  strongly 
  swollen, 
  slightly 
  imbricated 
  at 
  tip. 
  Cauda 
  short, 
  

   broad,
