edge of the wing is olive-ash ; the median vein is dark ; below a broad black longi. 
tudinal stripr runs from the base of the wing out towards the outer edge. The inner 
median line is dentate, while the outer is distinct, black, and scalloped. Marginal 
line blown. Expanse of wings, 2 inches. (See Figs. 42, 43, p. 13(3.)

Orgy ia -p. 
Order Lepidoptera ; family Liparid i. 
A larva quite different from Orgyia leucostigma occurs frequently on 
coniferous trees, including pines, spruce, and fir. It differs from tbat 
of O. leucostigma iu having a pair of large prothoracic lateral black 
pencils. 
Larva. — Differs from 0. leucostigma in having a pair of large prothoracic lateral 
black pencils, the posterior supra-anal tuft being as usual. The pair of lateral black 
tufts are about half as long as the anterior pencils and project straight out from the 
second abdominal segment, immediately in front of which is a pair of much slenderer 
cream-colored pencils also projecting straight out. Of the four dorsal tufts, the two 
anterior ones are smoky black, the two posterior ones dusky cream-colored. Behind 
the dorsal tufts are three coral retractile warts, and a lateral row of coral warts. The 
head is black. All the feet, both thoracic and abdominal, are yellowish. Length 20 mm . 
In another large Orgyia larva (whether of this species I am uncertain) 
found August 30 on the pine or spruce, the four dorsal tufts are colored 
alike, being tinged with reddish-brown, especially towards the end. 
Behind the last dorsal tuft are six coral warts from which pale hairs 
radiate, and there are three greenish median retractile warts, besides 
the lateral row of coral warts extending along the body. 
In the larva of 0. antiqua as described by Harris, the back is yellow, 
with four yellow tufts ; the sides are dusky and spotted with red ; there 
are two long black prothoracic pencils but no lateral prothoracic ones ; 
but a black pencil on each side of the fifth ring, and the usual one on 
the top of the eleventh ring ; the head is black, and there are two 
retractile coral warts on top of the ninth and tenth rings. 
98. The white pine tufted caterpillar. 
Platycerura furcilla Packard. 
Order Lepidoptera; family Noctuid.£. 
(Larva, Plate xi, fig. 5). 
Found in September usually on the white pine; a dull-red caterpillar, banded with 
brighter red; a white lateral line, with reddish hairs in clusters, and on the first, 
third, fourth, and eleventh segments two long pencils of red hairs ; spinning a cocoon 
among fallen leaves, the gray moth appearing about the middle of June. 
This is another interesting caterpillar, whose history has been traced 
by Mr. Lintner. The worm when in the attitude of feeding, with its 
terminal pair of legs clasps the leaves at the sheath, and extends its 
body along a leaf until it commences to bend, when, by detaching suc- 
cessively the first and following pairs of prolegs,it forces the leaf through
