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.
