Petrophora diversilineata, Hub. 
This commonly distributed species is to be found from June to 
August entering houses at night and settling on walls with its abdo¬ 
men curved over its back. It varies in size in expanse of 
wings of a little more than an inch and a quarter to over two inches. 
The body and wings are light ochreous-yellow, often pale in the mid¬ 
dle and basal portions. The fore wings are crossed by three rust 
brown curved lines, the outer strongly dentate in the middle. 
Beyond this is a sub-terminal faint line, not always distinct. 
The hind wings are paler than the fore wings, clear, usually 
without lines, except in the outer third near the anal angle, 
where there is a faint brown line edged on the outside with 
white. At the anal angle is a dark spot composed of two brown lines, 
with violet brown between them. The caterpillar varies from green 
to brown, spotted above, and the head larger than the first segment. 
It feeds on grape leaves. 
Eufitchia ribearia, Fitch.—The Gooseberry Span-worm Moth. 
This species has been known to writers generally as Allopia ribearia 
or by some as Abraxus ribearia , until the creation of the new genus 
Eufitchia , by Packard, in his late monograph of this family. The 
caterpillar is, when full grown, about an inch long, of a bright yellow 
color, with lateral white lines and numerous black spots and round 
dots. The head is white, spotted with black. These worms may be 
seen on gooseberry and currant bushes soon after the leaves open, more 
or less of them being found every year. It occasionally occurs in such 
numbers as to strip the bushes of their leaves, as it did in the vicinity 
of Chicago in 1862, and a few succeeding years. 
The moth is a pale ochreous yellow with a submarginal row of 
smoke colored spots on both wings, the middle of the wings being 
shaded with the same. 
In the latitude of Southern Illinois, the worms attain their growth 
about the first of June, when they descend to the ground and trans¬ 
form to brown chrysalids, just beneath the surface. The pupa state 
lasts about fourteen days, when the moths emerge to lay their eggs on 
twigs, where they remain till the following spring. 
Remedies. —Of the numerous remedies that have been recommended 
a dusting of the bushes with a white hellebore powder is probably the 
best. Of course, in dusting the bushes, the operator should stand on 
the windward side so as not to inhale the powder, as the irritating 
effect upon the nostrils would be unpleasant. If the bushes are trim¬ 
med up from the ground, the worms may be shaken off and killed.
