864 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



pearing late in Juue; the larva is not, however, known farther than 

 that its color is brown. 



The caterpillar of the present species was found June 23, at Bruns- 

 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 twig. Head rounded, 

 somewliat bilobed ; body with no humps. Supra-anal plate rounded, not pointed at 

 the tip, with six hairs. Color reddish brown with a greenish tint. Head greenish, 

 mottled, and finely spotted, especially on each side of the vertex, with reddish brown ; 

 a row of lateral irregular dark blotches. Length, 22™'". 



P«j)a. — 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™™. 



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 on the fore 

 wings. The female difters 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™™.

Order Lepidoptera; family Fhal.enid^. 



The following account was published by us in the American Natur- 

 alist : 



We have reared six moths from curious 14-flapped larvte found feeding iu August 

 on the fir and hemlock, and described in Bulletin vii, U. S. Eut. 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 

 inner 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 iu the middle of the body being the largest. Head angular on the sides, deeply
