yellow lines on e;u"h sitle. The light phase is pale yellowish throiigh- 
oLit with few or many small black specks on the dorsum; amber ven- 
tral surface and prolegs and black head and true legs. The length 
varies from 1 J/ to 2 inches. 
The caterpillars are often \ery numerous, feeding on nearly e\ery 
part of the plants. The \ery young ones spin but small webs o\er 
themselves near the middle of the leaves, and it is not until they are 
nearly half-grown that they are able to draw together and fasten 
the edges of the lea\es and make a more roomy abode. L'nlike the 
caterpillars of some of the other species, they remain in their nests 
feeding on the leaxes under the webs until nearly all ha\e been de- 
voured, when they seek a new leaf, make another nest and begin 
feeding as before. The work (Pig. 5) is such as to cause the plants 
to appear quite ragged and unsightly, and serves to quickly detect 
their presence. When ready for pupation the caterpillars leave the 
nests and seek some more hidden and secure spots not easily found. 
The chrysalids ( Pig. 6) are light-gray or grayish-brown with two 
distinct and two much smaller silvery-white spots on the dorsum at 
the constriction between tlie thorax and the abdomen. The surface 
is more or less faintly, and in some ilistinctly, iridescent golden. The 
length averages about -^s of an inch. I- rom a large number of 
chrysalids only a \ery small percentage de\'eloped into butterflies 
because of the effectual parasitism of a tachina fly, Plioroccra satiii- 
dersii Will. Many of the parasitized chrysalids could at once be 
told by a copious bleeding, the liquid hanging in long slender threads 
which became dry and brittle. It is a conservative estimate to say 
that at least 85 per cent, were thus destroyed. 
The butterflies (Figs. 7 and <S ) are much like the adults of I'li- 
iii's.ui hiiiiind (Fab.) and I aiics.ui ccirdiii ( Lmn. ) . The presence 
of more than two eye-spots on the under side of each hind wing 
separates them from the former, and the truncate apices of the front 
wings or the presence of the continuous black band across the middle 
cell of each front wing will distinguish them from the latter. There 
is rarclv a distinct rosy tint on the front wings instead of the tawny 
color. The eve-spots on the under surfaces of the hind wings are 
fairh' distmct, consisting ot four (]uite large and perfect ones and 
one smaller anterior imperfect one on each. The bodies are faintly
