the other somewhat, is a little smaller, expanding from three to four 
inches. The color of the body is a more uniform olive gray, darker; 
the shoulder tufts darker, the fore wings are dark olive gray, with 
some faint brown marks, and three.dark olive, almost black spots ; as 
in the preceding, the one on the hind margin being square and 
the middle. Hind wings, roseate in the basal half, a band of dark,. 
then a border of olive.

The caterpillar of this species is usually spoken of as the u Hog Cater* 
pillar of the vine,” as it feeds on all our grape vines, and because the 
peculiar appearance of the fore part of the body suggests the fat cheeks 
and shoulders and the small head of a well kept hog. This caterpil¬ 
lar is by far the most common of the large caterpillars that are found 
on "rape vines in this part of the United States, there being scarcely 
a season it is not found doing some damage in every place where vines 
are grown. . , 
The eggs are perfectly round, of a uniform yellowish green color, 
and are glued singly to the underside of the leaf. The young worm 
that hatches from the egg is pale green, with a straight horn at the 
tail. It comes to maturity in lour or five weeks, and is then either of 
a pale green color, with a light stripe each side, that unites with the 
one from the opposite side at the horn, and a dark spot on the front 
part of the dorsum of each segment, bordered by light, posteriorly; or 
a brown color, with the same markings. These colors do not repre¬ 
sent different varieties nor difference of feed, but may be found in the 
different individuals produced from eggs from the same mother, as I 
have found by experiment. Length, when full grown, an inch and a 
half. When about to change, this caterpillar descends from the vine, 
and binding together loosely some leaves or other rubbish that may be 
at hand, transforms to a chrysalis, a little more than.an inch long, of a 
pale yellow color, with the divisions between the joints and the stig¬ 
mata brown, and some specks of the same color over other parts. 
The moth expands about 2.25 inches. The fore wings and the bod) 
are a gravish lilac color, with olive green on the back, a narrow 
bar of the same across the wings, near the body, and a broad,, irregulai 
one across the outer part. The hind wings are red, with a little gra\ 
near the anal angle. . . , 
Remedies —Nature has provided, in the shape of a little black lch 
neumon flv, all the remedy that is generally necessary for keeping 
these worms in check. The eggs of these parasites are depositee 
within the body of the caterpillar while it is young, and, after hatch 
ing, they feed upon the fatty substances of their victim till the cater 
pillar passes the last moult, after which they push themselves througl 
the skin of different parts of the body, holding only by the las 
segment, where they form their little white cocoons, each containing 
the pupa of an ichneumon fly. Worms found thus parasitized shoulc 
not be molested, as they will themselves succumb to the influence o
