568 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
moths escape from the hibernating cocoons in June, as reported by 
observers in Canada* and Massachusetts^ and the larvae are reported 
only in September and October, during which months thepupse arc 
found. Previous to the pupation the larva- spin a cocoon of sjlk 
within a hunch of Leaves, or sometimes attached to a twig." (Forbes.) 
Ailing c<«]<»r. blaok. Each joint with a transverse, dorsal, crimson-red 
band across tin- middle bom stigmata to stigmata, and containing six warts, each 
famishing ten or twelve or mora stiff yellow or fulvous bristles, and the two dorsal 
<>ne> being farthest apart. A subdorsal, longitudinal, yellow line, interrupted by 
this transverse hand and at incisures in Buch a manner that the black dorsum ap- 
somewhat diamond-shaped on each joint. A broad, wavy, bright-yellow 
matal line, containing a yellow bristle-bearing wart in the middle of each joint. 
Lateral space occupied with different sized pale yellow spots, largest towards dor- 
sum. Head chestnut-brown. Venter crimson-black, with bristle-bearing wai 
the same color. Stigmata oblong-oval aud pale. Thoracic legs black ; prologs with 
black extremities. Such is the normal appearance of this larva, but it is very vari- 
able. In some the yellow seems to predominate over the black, and there is a mora 
or less distinct dorsal line. In some this dorsal line forms a mere speck at the in- 
cisures of the middle joints. The transverse crimson band is often entirely obsolete, 
and the warts distinctly separated, while in others, wher • this band is distinct, the 
warts frequently coalesce. (Riley.) 
Papa. — Almost black, and shagreened with the exception of a smooth and polished 
rim, at posterior border of joints, which become reddish, especially ventrally, on the 
three joints immediately below the wing-sheaths. Terminal joint horizontally com- 
pressed, squarely cut off, aud furnished with a little brush of short, eveuly-shorn, 
stiff, rufous bristles. (Forbes' Second Rep. Ins. Illinois). 
moth. — Front wings oblong; apex more or less prolonged ; posterior margin 
sometimes rounded, sometimes straight; color ash-gray, caused by numerous dark- 
brown atoms more or less suffused on a white ground, from which the ordinary lines 
are barely discernible in the better marked individuals; a row of distinct black dots 
along the posterior border; the ordinary spots represented by blurred marks or en- 
tirely obsolete ; the undulate line across posterior fourth of wing distinct, and re- 
lieved inside by a pale coincident shade, with the teeth quite aciculate and with the 
psi-spot so characteristic of the genus, but rarely traceable; fringe narrow and gen- 
erally entire. Hind wings pure white, with a faint row of dark spots around the 
posterior border. Under side of both wings white, with a faint fulvous tint and 
faint irrorations; each wing showing the brown discal spot aud the row of points 
at the posteiior border. Head and thorax speckled gray ; abdomen whitish-gray: 
antennae short, simple in both sexes, gray above aud brown below : palpi small. 
Two specimens with the front wiugs very dark, showing the ordinary lines and 
spots conspicuously, and with the antenna- brown above as well as below. Average 
length, 0.75; expanse, 1.75 inches. (Riley.) 
23. Apatela. 
Mr. H. H. Wilder kindly presented me with two lame of this species 
found at Brunswick, Me., August 20. 
Larva. — Rather large, of the usual shape, regularly tapering towards each end ; 
head all black except the larval antennal joints. Body dull livid green with abroad
