gives off a spur that runs to the hind angle. At the end of the sec¬ 
ond line and the spur, start two short parallel lines that run to the 
costa, the latter at the level of the first line. The third longitudinal 
line runs along the hind margin and, in the terminal fringe, round 
to the apex. Hind winjgs a more or less bright scarlet red, marked 
with several black spots in the outer border. Body, black stripe on 
the dorsum, with red each side. 
The larva of this may be found in grass in the latitude of Southern 
Illinois, the fore part of May. It is a black, hairy caterpillar, an inch 
or more long, with transverse rows of wart-like tubercles, from which 
spring spreading tufts of short white hairs. Along the dorsum is a 
line of pale yellow, sometimes almost white. Those I reared the past- 
season were fed on grass, corn, peach, elm and grape leaves, Polygo¬ 
num aviculare , and Pepper grass (Lepidium Virginianum )—all of which 
they ate readily, except the first and last. The first spun its cocoon 
the 22d of May, from which the moth emerged June 16. As they are 
very abundant here in June and July, and then again in the fall, it 
is evident there are two broods in a season. 
Arctia arge, Drury—The Arge Tiger Moth. 
This expands two inches, but the wings are proportionally nar¬ 
rower than the preceding. The general color of the wings, light 
flesh, fading to buff. In the discal cell of the fore wings are two 
black dashes, the second or outer one somewhat kidney-shaped. Be¬ 
yond the cell are four others, placed two and two, the last pair at the 
apex. Below the last, in the middle of the outer margin, are twp 
more, with two more pairs of unequal size, and one of each pair tri¬ 
angular in the middle of the wing, and a row of three long dashes on 
the hind margin. Hind wings with several black dots near the outer 
margin, and three in the central part of the wing; a black line on 
the dorsum and near the shoulder tufts. _ # 1 
The larva is dark brown, with five pale or yellow longitudinal 
stripes, each segment bearing a transverse row of brownish yellow 
tubercles, from each of which arises a tuft of brown hairs. They are 
not so common here as the preceding species. Food plants, plan¬ 
tain, and, according to Abbott, it is sometimes destructive to corn in 
the Southern States.

The larva of this moth is known familiarlv as the “Hedgehog cater-

pillar,” from the fact that when taken up, it rolls into a ball, ana the 
thick masses of hairs with which the body is covered, project outward 
in every direction like the quills of that animal. It is to be met 
with in gardens, walks, and other places during the last of August, 
seeking a place of shelter, in which it may pass the winter. It feeds 
upon the leaves of clover, dandelion, plantain, etc., until the approach
