of the outer margin, and another on the anal angle, preceded 
by a black spot. Another black spot rests on the middle of 
the hinder margin; one on the middle of the costa, and an- 
other between this last and the end of the wing. Under side 
of hind wings, pale.yellow or buff, with a brown blotch on 
the outer margin, and a scarcely visible, dull, silvery lunule 
near the middle. Inside of this is a row of brownish points, 
corresponding to the black spots above. Across the middle 
and basal parts of the wings are several irregular, a 
lines. Body blackish above, white underneath. 
This species feeds on different species of Asters, both wild 
and cultivated. There are two broods in a year; the one de- 
scribed above is known as the form morpheus, and the one 
appearing in the early part of the season is the form marcia, 
and scarcely differs on the upper side, but has the under side 
of the hind wings more or less silvery on the basal part, 
and the terminal lunules silvery, with a pale, lilac tint. 
The eggs are laid in clusters of two hundred or more, 
sometimes in three tiers, usually on the under side of the 
leaves. They are pale green, conoidal, depressed at the top, 
and rounded at the base; the lower half indented like the 
surface of a thimble, the upper half with about fifteen ver- 
tical ribs or flutings. Duration of this stage, four to seven 
days. The young larva is .06 of an inch long, with a dark 
brown head, and a yellowish green body clouded with brown, 
with scattered black hairs, those on the forward segments 
‘directed forward. 
The first brood passes four molts before reaching maturity, 
when it is .85 of an inch long, with a heart-shaped, shining, 
bronze-colored head, with two oblique white stripes on each 
side, and a spot of the same color above the mouth. The 
body is dark brown dotted with yellow, and has seven rows 
of tapering, fleshy spines armed with blackish bristles. 
The larve of the second brood feed, and pass three molts, 
when they become lethargic, and hibernate during the winter ; 
and in the spring they revive, go to feeding, and molt twice 
more, after which, they change to pup; and in from one to
