Larva —Deep brown, an inch and a quarter long; head, reddish black- 
the body round, pointed, and striated with yellowish and whitish- 
all the body, except the second segment, covered with blacked,forked 
spines. Along the feet a line of citron-yellow, and above the stigmata 
another of the same color, marked with a row of red spots. 
Ihe caterpillars feed on the leaves of elm and bass wood or lime 
tiees, and the hop vine. Harris remarks that they sometimes occur 
in such numbers on the latter as to defoliate the vines. They may be 
taken from the vines and destroyed if they become numerous enough 
to be seriously injurious. There are two broods of the Butterflies in a 
season the first in May, and the latter in August and September. 
Expands from two and a half to near three inches. 
Grapta comma, Harris—The Comma Butterflv. 
V 
1 his butterfly, common in some parts of the State, is similar to the 
preceding, but may be known by its having a silvery comma in the 
midle of the hind wings, instead of a semicolon, and bv its being 
smaller. The larvae feed on the hop and elm, and have also been 
found on a broad-leaved species of nettle. They are spined like the 
preceding, in color are white, mottled or striped with gray or ashen 
and with red stigmata. 
Grapta faunus, Edw. 
Expands two inches. Resembles the Comma Butterfly, but is 
smaller, the ground color more uniform reddish brown, and the outer 
border of the wings darker. Under side of both wings, dark brown 
next the base, with an irregular band across the middle. Beyond 
this the brown is paler and finely mottled with grayish white “run¬ 
ning more or less in veins, and some spots of olive-green near the 
border. In the middle of the hind wings a silverv letter G. The 
larva is said to feed on gooseberry leaves. 
Grapta gracilis Gr. 
Expands two and a quarter inches. Base of wings reddish brown, 
the outer half yellowish brown, the border scarcelv darker, black 
spots as in the others. Under side of the basal half of both wings 
brown, crossed through the middle by a yellowish brown, irregular 
line. Beyond this the brown is lighter and mingled with a golden 
yellow, and crossed lengthwise by grayish white veins. Some dark 
in the outer border. In the middle of the hind wings a silver G like
