46 BUTTERFLIES OF MAINE. 
18. PuHyciopEs NycTEIs, Doub. 
Phy-ci-o'-des nyc'-te-is. 
Expanse of wings, one and three-fourths inches. 
Upper side of the wings very much like those of Phycio- 
des harrisitt. Under side of fore wings, pale orange, faintly 
showing the black markings of the upper side. A pale yel- 
low line runs along the outer margin, bordered on each side 
by a fine brown line, and preceded on the apex, and near the 
middle of the outer border, by a few white lunules. Under 
side of hind wings, dark brown, broken somewhat by whitish 
and pale yellow. <A row of large, silvery white spots across 
the wing near the base, a similarly colored band across the 
middle of the wing, broken by the brown veins, and edged 
en the outside by a scalloped brown line. Between this and 
the outer border, onthe brown shade, is a row of round black 
spots, re-produced from the upper side. A terminal yellow 
line, with brown edges similar to those of the fore wings, Is 
continued along the outer border of the hind wings, within 
which is a series of unequal, silvery white lunules, the middle 
one being much the largest. 
Body, above, blackish; beneath, white. 
The larve feed on Diplopappus umbellatus, Aster, Heli- 
anthus and Actinomeris. As these wild plants are of no 
value, the insect has but little economic importance. 
The eggs are laid in clusters of about a hundred, on the 
under side of the leaves. The eggs are whitish green, some- 
what in the form of a truncated cone, the lower third of the 
outside smooth; the middle part marked with hexagonal, 
irregular, very shallow cells, and the remainder, by vertical 
ribs, terminating at the rim of the top. Duration of this 
stage, nine to thirteen days. 
The larva passes four molts before reaching maturity, when 
it is an inch in length, of a blackish brown color above, and 
greenish brown beneath. Head, shining black, heart-shaped, 
with the sides high and rounded, and clothed with numerous
