longitudinal lines cross the yellow bands and disappear in the black 
areas between. There are two yellow lines on the sides, the upper 
one markeei 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 C()\ered with brown hairs, the 
under side being sprinkled with small white or veUow specks. The 
true legs are black and the prolegs purplish-brown'. Ilie lar\-s 
may be fountl scattered o\er the food plants and make nests by 
ch^awing together the lea\'es, bits of steins and other fragments of 
the plants, lea\ing but a small exit and entrance hole. 
The chrysalids are yellowish or light-brown and irregulai-ly 
marked with large golden blotches. 
The butterflies ha\-e a wing expanse a\ eraging about 2 inches and 
a body length of about ?,s of an inch. The upper surface of the 
wings is reclclish-brown or tawny with numerous black and white 
markings, as shown in I'ig. 2. Fhe 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 
ti\'e, 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 rosv area 
near the middle of ti.e 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 i-eadily 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 abo\e and light-gray beneath. 
The caterpillars feed upon the following plants: common or 
plumed thistles ((.'iiIiks spp.), plumeless thistles ( ('urdiins spp.), 
nettle, burdock, cotton or Scotch thistle ( Oiioporilmi iiiiiiilliiinn 
I.inn.), hollyhock, sunflower, mallow, milk thistle (Silxhiiin iiuiri-
