one of the destructive cut-worms in field and gardens at that place., 
C. E. Worthington, of Chicago, mentions it as one that does con¬ 
siderable damage in that vicinity. Other instances might be given. 
The general color of these worms is flesh gray, with elongate patches 
on the sides, a creamy stripe along the stigmata or breathing pores, 
and triangular black patch just before the anal extremity of the body. 
On the top of each segment is a bright yellow point which is especially 
distinct in the anterior part of the body. Besides these marks the 
upper surface is irregularly mottled with fine dark spots. As the 
worm increases in size it grows lighter, and the light stripe along the 
side is frequently a series of blotches instead of a line. 
The moths vary considerably in different individuals. The general 
color of the fore wings is dark brownish gray, with the front part in 
some specimens, almost black, while in others this space is dull golden 
buff, with dark brown or black points along the edge of the wing. In 
the dark specimens the stigmata are darker than the ground color,, 
with hardly a trace of the double wavy bands, but in the light speci¬ 
mens these two spots are lighter than the ground color and the trans¬ 
verse bands show plainer. 
There are probably two broods of the worms in a season, the first- 
changing to chrysalids the last of May and issuing as moths twenty 
days later, but how the second pass the winter is a question not- 
fully settled. Prof. Riley states in his writings that it is probable 
they hibernate in the moth state and deposit eggs in the spring on 
the twigs of different trees and shrubs. The 6th of last April I 
captured a fresh specimen, which should indicate that they pass 
the winter in the chrysalis state. 
Spec. Char. Larva .—Length from 1.50 to 2.00 inches. General color- 
varying from light to dark gray, finely mottled with light brown 
and very dark brown or black. The eleventh segment is slightly 
raised, and contains a triangular black or dark brown mark. There 
is usually no continuous dorsal line, but a little back of the middle 
of each segment is a more or less bright yellow point, generally 
the brightest in segments 3, 4 and 5. On some of the older and 
paler specimens these points are not perceptible in the posterior 
part of the body. In the subdorsal region a series of elongate black 
or dark brown spots, in length nearly one-half the width of the 
segments, each beginning at the anterior part of the segment. The 
space between the dorsal and subdorsal regions and thence to the 
stigmata is mottled with dark, the sides a little the lightest. Below 
the stigmata is a yellow or carneous stripe, in the lightest specimens 
broken up into elongate spots. Piliform spots not prominent, mostly 
of the same color as the body, a very short hair from each. Under 
side, legs and prolegs, glaucous gray, speckled. Head light gray, 
speckled; the centre of the eyes clear, on the inner edge a dark band. 
Cervical shield nearly obsolete. 
Moth .—Expanse of wings 1.80 inches. Ground color of fore wings 
gravish brown more or less marked with dull buff and smoky 
black. Different specimens vary much. In some the front part of 
the wing is smoky black, with the rest of the wing yellowish brown, 
rather dark; in others the costal space to the antiapical is buff, with 
a slight grayish tinge to the brown of the rest of the wing : in an¬ 
other form there is a buff band from the base along the costa to the
