864 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
pearing late io Jane; the larva is not, however, known farther than 
that its eolor is brown. 
The caterpillar of the present species was found June 23, at Brans- 
wick, Me., on the fir; on the 27th it became a chrysalis, and the moth 
escaped about a week or ten days later. 
Larva. — Body cylindrical ; in color and appearance like a fir t wig. Head rounded, 
■Omewhftt bilobed ; body with no humps. Supra-anal plate rounded, not pointed at 
the tip, with six hairs. Color reddish brown with a greeuish tint. Head greenish, 
mottled, and linely spotted, especially on each side of the vertex, with reddish brown; 
■ row of lateral irregular dark blotches. Length, 22 mm . 
Pupa.— Of the usual shape, but rather stout; dark tan-brown in color. Terminal 
spine (cremaster) large and stout, the surface corrugated at the base; ending in a 
fork, each branch of which ends in two excurved hooks. Length 12 mm . 
Moth. — Forewings subocherous, with a median whitish baud, beneath ocherous. 
The male may be distinguished by its smaller size, by the wings being more ocherous, 
by the distinct discal dots, and by the rather distinct median white band en the fore 
wings. The female differs greatly from the male, being much larger and with the 
wings more serrate, the two inner lines more or less obsolete, the border of both 
wings being much darker than the inside of the wing, the border sometimes having 
a lilac tinge. From the female of P. subatomaria it differs in its still smaller size, in 
having usually but one subapical spot instead of three, as is usually the case in the 
other species, and in the outer border of the wings being darker or more decidedly 
ocherous. The wings of the female are more deeply serrated than in the other species. 
Expanse of wings, 22 to 35 mm .

Order Lepidoptera; family Phal.enid.e. 
The following account was published by us in the American Natur- 
alist : 
We have reared six moths from curious 14-flapped larvae found feeding in August 
on the fir and hemlock, and described in Bulletin vn, U. S. Ent. Comm., p. 238, and 
referred by us to Aplodes. The caterpillar is dull, brick-red, with seven pairs of 
broad dorsally-situated flat flaps on each side. It bears a striking resemblance to the 
small reddish twigs of the fir with the leaf scars. 
From the 4th to the middle of September the caterpillars made between the twigs 
a loose, slight, open cocoon of bits of small twigs and leaves, held together by silk, 
within which the pupa rested through the winter. 
Walsh's description of the larva of Aplodes mimosaria, which he bred from the oak, 
is too brief for comparison, but our specimens do not disagree with his diagnosis, 
though we have never found it on the oak, but frequently on the coniferous trees 
mentioned. 
On sending specimens to Mr. J. A. Lintner, to compare with his types of the species 
in his possession, he kindly writes as follows: 
" Differs from mimosaria in the outer line of front wings being nearer to the margin 
and the inner line being angulated on the submedian instead of curved. The outer 
line of secondaries is nearer to the margin than in mimosaria and is more regular. 
" It approaches nearer to latiaria, but the two lines are more approximate, and the 
innei line is more angulated on the submedian. It also has an inner line on the 
secondaries which latiaria has not." 
Larva. — It bears a striking resemblance to the small reddish twigs of the fir with 
the leaf-scars. Body dull brick-red. with seven pairs of broad flat flaps on each side. 
those in the middle of the body being the largest. Head angular on the sides, deeply
