Argynnis bellona, Fab. 
This species is almost if not quite indistingishable from A . myrina 
in the preparatory stages; the egg is slightly longer with the sides 
less rounded; the spines on the second segment of the larva are 
not lengthened, as in myrina. Like that species and the others of 
Argynnis, it feeds on Violets. 
Melitaea phaeton, Dru. 
The young larva of this species is less than one-lialf of an inch 
long, and is found early in the Spring, under dead leaves. When 
full grown, it is cylindrical in form, with the head slightly angu- 
lated; body of a deep orange color, excepting the head, thorax 
and last three segments, which are black; covered with black raised 
tubercles, from which proceed rather long fleshy hairs. These 
tubercles are arranged in nine longitudinal rows, with black lines 
running between the rows, black dots along each side of the body. 
Feeds on Chelone glabra, Lonicera sciliata, and Plantain; covering 
the summit of the plant on which it feeds with a web, under which 
the caterpillars live in swarms. The butterflies appear in June and 
July. 
Melitaea tharos, Dru. 
This larva is found on the under side of the leaves of the Aster 
and Sunflow 7 er ( Actinomeris helianthoides) in May and June, and 
again in July and August. When young it is about .06 of an inch 
in length, largest anteriorly; of a clouded yellowish green color; 
sparsely covered with black hairs; after the first molt, merely 
hairy; after the second molt the spines are distinctly seen. The 
first brood molts five times; the second, four. The larva, when 
full-growm, is .85 of an inch long; of a brownish black color dotted 
with yellow, more thickly on the back; usually a black dorsal stripe, 
though this is sometimes wanting. Body longitudinally striped 
with yellow and black; seven longitudinal rows of short fleshy 
spines, thickly surrounded by browm bristles with black tips; head, 
shining bronze with black hairs, marked in front w 7 ith whitish and 
yellowish. 
Melitaea nycteis, Doub. 
Young larva about .05 of an inch in length. Body pale yellowish, 
with darker raised dots, from each of which proceeds a single pale 
brown hair; a yellow spot on the top of the last segment; head 
dark greenish brown, when full grown the upper side is brownish 
black, with greenish spots; a transverse row of tubercles on 
the second segment, from which proceed blackish hairs; four 
black branching spines on each of the third, fourth and last seg¬ 
ments ; each of the other segments has six spines, the two upper 
pairs black at the base and greenish at the tip; a pale greenish 
white circle around the lower pair of spines; the spines on the term¬ 
inal segment are arranged in two pairs, one above the other; 
underside pale greenish; feet tipped with black; pro-legs pale, semi- 
transparent.
