wheat, Panicum, and Setaria are listed as food plants. We have taken it 
from May to November, especially in midsummer; the nymphs from 
July to October. It is also recorded as attacking the cotton-worm 
(Aletia).

This species ranges from Florida to Oklahoma and Texas, and 
southward into Central America, with one record for Philadelphia. The 
species was taken by the author in extreme southern Illinois June 4 to 10, 
at Parker, Pulaski, and Cairo, in the latter place under electric street- 
lights. The food plant is given as cotton, but there is very littl or none 
of this in the vicinity of the localities named. It is also said to prey upon 
the cotton-worm. .

The range usually recorded for this species is from western Canada 
to Lower California, west of the Rocky Mountains. Stoner records it, 
however, from Iowa City and Ft. Madison, Iowa, in sandy ground. Since 
the latter locality is on the Mississippi River opposite Illinois the species 
should be looked for in the extensive sand-regions on the Illinois side of 
the Mississippi in this vicinity.

Recorded from Canada, and ranging across the northern United 
States from Massachusetts to California, south as far as Arkansas. “Ap- 
parently nowhere abundant.” (V.D.) In our collection from northern 
Illinois ; from Quincey, White Heath, Urbana, St. Joseph, Homer, Muncie, 
and Hillery, in central Illinois; and from Dubois and Anna (S. Ill.). 
Nymphs in June; imagines from March to November. Its infrequency 
in collections is doubtless due to its arboreal habits. Van Duzee records 
its capture in numbers from small hickory trees; and in late October and 
early November we found it very abundant on sidewalks on the campus 
of the University of Illinois under a row of hard maple trees, which it 
was presumably leaving for hibernation.
