longitudinal lines cross the yellow bands and disappear in the black 
areas between. There are two yellow lines on the sides, the upper 
one marked with an orange spot immediately above each spiracle. 
There is a white spot on each side of the dorsal line on the middle 
segments. The head is black and covered with brown hairs, the 
under side being sprinkled with small white or yellow specks. The 
true legs are black and the prolegs purplish-brown*. The larve 
may be found scattered over the food plants and make nests by 
drawing together the leaves, bits of stems and other fragments of 
the plants, leaving but a small exit and entrance hole. 
The chrysalids are yellowish or light-brown and irregularly 
marked with large golden blotches. 
The butterflies have a wing expanse averaging about 2 inches and 
a body length of about 5¢ of an inch. The upper surface of the 
wings is reddish-brown or tawny with numerous black and white 
markings, as shown in Fig. 2. The number and arrangement of 
the white spots on the front wings are not greatly different from the 
preceding species, excepting that the outer row has four instead of 
five, and arranged in the form of a crescent. The larger somewhat 
rectangular-shaped spot on the costal margin is more often yellow 
or tawny than white. Near the apical margins of the front wings 
are two purple lines and two shorter ones of the same color near 
the anal angles. The under surface is not so brightly colored as 
the upper surface, and, with the exception of the tawny or rosy area 
near the middle of the front wings, consists of a mixture of pale- 
browns and grays, with a faint purplish line extending along the 
outer margins of both pairs of wings. The most conspicuous mark- 
ings are the two large eye-spots on the under side of each hind wing, 
which readily separates the species from the others. The body is 
dark-brown above with greenish iridescence and thickly beset with 
brownish hairs. The ventral surface is pale-gray. The palpi and 
legs are brown above and light-gray beneath. 
The caterpillars feed upon the following plants: common or 
plumed thistles (Cnicus spp.), plumeless thistles (Carduus spp.), 
nettle, burdock, cotton or Scotch thistle (Onopordon acanthium 
Linn.), hollyhock, sunflower, mallow, milk thistle (Silybum mari-
