Apatela rubricoma, Guen. 
The larva of this species measures 1.25 inches in length. It is 
of a yellowish-green color, and has a blackish dorsal stripe, on each 
side of which is a yellow line; a thick tuft of hair, about half an 
inch long, arises from the posterior part on the top of segments 3, 
4, 5, 6, 7 and 11; these are white in the younger specimens and 
blackish in the older. The remainder of the body is more or less 
covered with tusts of white hairs about half an inch in length. 
Head black. In a curled position when at rest. Feeds on Hack- 
berry leaves. Found in June and in September; the moth from 
the June caterpillar appears in August. 
Agrotis c-nigrum, Linn. The Black-C Eustic. 
This larva is known as the “Spotted Cut-worm,” and when full- 
grown is 1^ inches in length, of a uniform dark greasy gray color, 
lighter underneath; with two rows of elongated black patches along 
the hack, which occupy the posterior two-thirds of each segment, 
and are more distinct on the posterior part of the body than the 
anterior. Previous to the worm casting its skin the last time, there 
is a fine yellow line just outside these patches. In the lighter 
specimens the ground color on the back, between these spots, is 
variegated a little so as to show a faint diamond-shaped spot on 
the middle of each segment, the two darkest points being at the 
posterior and anterior parts of the segments. Sometimes the ground 
color has a slightly brownish tinge, which under the pocket lens 
is seen to he caused by minute brown spots; in these specimens 
the black elongate patches are nearly obsolete on the anterior part 
of the body. They are found in March and April feeding on Grass, 
Vegetables, Pear tree and Maple (Acer dasycarpum). 
Agrotis subgothica, Harr. The Gothic Dart. 
This larva, known as the 
“Dingy Cut-worm,” is one inch 
in length, of a dingy white color, 
with a pale buff dorsal line, 
edged on each side with an ob¬ 
scure dark line, and three* in¬ 
conspicuous broader lines on 
each side; stiff short hairs arise 
from piliferous spots. Head 
dark, finely sprinkled with white. 
Fig.44— Agrotis subgothica. Moth. Found in June in gardens cut¬ 
ting off plants indiscriminately; the chrysalides are formed in July, 
and the moths issue in September. 
Agrotis tricosa, Lint. The Perplexing Dart. 
But little is known of the larva of this species, but as the moth 
is very closely related to both the subgothica and herilis, it is quite 
probable that the larva also resembles the larvae of those species.
