Eudryas unio, Hubn.—The Pearly Wood-nymph. 
Expands nearly an inch and a half. The fore wings a pearly white, 
with a purplish brown stripe sprinkled with white along the costa 
from the base to beyond the middle and a terminal border of the 
same, through which passes a whitish band, dentate without and pow¬ 
dery within, with a few dark spots. This terminal brown border is 
is lined on the inside by an olive brown line that extends along the 
hind margin, being interrupted in the middle of margin by a gray 
spot. Hind wings yellow with a terminal brown border similar to 
the fore wings but a little lighter, and a brown spot near the anal 
angle. Wings yellow underneath, with brown terminal border, two 
black spots on the fore wings and one on the hind. 
The larva, when full grown, is about an inch long, with the body 
tapering from the eleventh segment to the head, the eleventh seg¬ 
ment, as with the rest of this group, containing a prominent dorsal 
hump. On each of the segments there are three transverse black 
stripes, and then white ones each side of an orange stripe, the orange 
stripe the broadest and marked by six black spots. Head orange, 
spotted with black. 
The grape-feeding habit of this caterpillar is doubted by many en¬ 
tomologists, but is affirmed by Dr. Fitch. Mr. Lintner, of Albany, 
N. Y., has found it feeding on Epilobium coloratum. while Mr. Kirk¬ 
patrick claims that it bores into the stems of Hibiscus. Last season 
(1877) I found two specimens of caterpillars on grape-vines that I took 
to be this species, but as I bred tachina flies from them instead of 
moths it is impossible to tell whether they were this species or the 
Emmemis 
Remedies —Same as the Eight-spotted Forester, if it should be found 
that this feeds on grape. 
Eudryas grata, Fabr.—The Beautiful Wood-Nymph. 
This is similar to the preceding, but differs in the following partic¬ 
ulars: The purplish brown stripe and border of the fore wings are 
darker, containing very little white, and the line between the border 
and the white, ground color of the wing, is green instead of brown, 
with the same color below the costal stripe. On the hind wings the 
border occupies only the anal half of the terminal edge, and there is 
no border underneath to either pair of wings. The larva is, when 
full grown, an inch and a half long; the giound color somewhat blu¬ 
ish, with six irregular black transverse stripes to each joint, three 
each side of an orange stripe. On each segment are about eighteen 
black spots, the six above the stigmata in the orange stripe, and 
against the black stripes each side. Head, yellow, spotted; the 
cervical shield same color, with eight spots in the transvei&e rows. 
The food plant usually given for this is grape vine, but I found them 
in Central New York, in 1869, feeding on a Virginia creeper that had 
been trained along the upper part of a piazza. It pupates by boring
