omnivagus Knight. Genital claspers distinc- 
tive, fig. 164. 
FEemMALe.—Length 5.00-6.30, width 2.30; 
more robust than male, frequently with 
brownish yellow areas between the calli and 
over posterior part of disk. 
Specimens which are towards the pale end 
of the series with a more or less prominently 
banded effect represent the variety subfuscus 
Knight (1917, p. 616); they resemble om- 
nivagus in coloration. Specimens that show 
all ranges of color have been taken in IIli- 
nois, frequently both extremes and the inter- 
grades together on the same tree. 
Foop PLants.—Hickory (Carya ovata) 
and pecan (C. illinoensis). Also, single Illi- 
nois specimens were taken on locust (Rodi- 
nia pseudoacacia), oak (Quercus sp.) and 
red cedar (Juniperus virginiana). There is 
no evidence that they fed on these hosts. 
Of recent years this species has been re- 
ported several times as causing “cat-facing” 
on peaches in New York and Ohio. ‘The 
species may breed on nearby hickory trees 
and, when mature, fly to the peach trees 
where they puncture and feed upon the 
young fruits.

rior femora, and apices of corium and of

gave Texas as the type locality for vitticollis, 
but Mr. W. L. McAtee examined the type 
in the Stockholm Museum in 1927 and re- 
ported that it was labeled ‘‘N. Y.”
