Moth . — Two ^ , 1 $ , Oclierous yellow aiul roseate. Head and body rosy pink. Base of the 
fore wings roseate, bounded externally by a pink line bent at a right angle upon tlie first anal vein 
(Yl), Between this line and tlie outer one the wing is ocherous yellow; outer edge of the wing 
pink. Hind wings white, either unspotted or with a x)ink line along the edge; a slight pinkish 
discoloration at the internal angle. Abdomen roseate at the end. The legs are tinged externally 
with roseate. Length of body, 15-20 mm.; exjainse of wings, 30 mm. 
The young were reared from eggs kindly sent me June 20 by Miss Emily L. Morton, of ]?^ew 
AYindsor, N. Y. 
Larva, Stage I. — Length, 2.5 mm. The head is very large and broad, about twice as wide as 
the rather slender body, and dull honey- yellow or chitinous in color; with a few long light hairs 
in front near the vertex. On the prothoracic segment are two rather large acute conical dorsal 
tubercles of the same color as the head and larger than those on the iirst or eighth abdominal 
segments, though all the dorsal tubercles on tiie body are unusually large, larger in x>i’ 0 ])ortion 
than ill the first stage of 8chizura; those on the second and third thoracic segments are well 
develoxied, but cousiderably smaller than those in front. Those on the first abdominal segment 
are situated close together, Avhile those on the first thoracic segment are rather wide apart. The 
two on the eighth abdominal segment are not quite so large as those on the first abdominal 
segment. The glandular hairs arising from these tubercles and those on the side of the body are 
long, varying in length, and distinctly bulbous at the end, those on the thoracic and x^osterior 
thoracic segments being longer than those in the middle of the body, or in the allied genus 
Schizura. 
The body above ])a\e yellow, with a greenish tinge, the sides of the body being cherry-red. 
The first, third, and eighth abdominal segments are cherry-red all around, including the tubercles,, 
so that the body is . thrice ringed Avith red. All the dorsal abdominal tubercles are quite large, 
those on the first and eighth segments scarcely larger than those on the other segments. The end 
of the body i.s ux)lifted, both when walking and at rest. All the abdominal legs are reddish, and 
the thoracic legs are dark. 
Stage II . — Just molted, July, 1S91. Evidently delayed in its growth. Length, G mm. Head 
moderately large (now wiiler than the body, as the larva has not begun to feed); it narrows 
slightly above, aiuj bears on the vertex two x>iliferous warts which are somewhat larger than 
those below on the face, of which there are five, rather large conical warts, arranged in two rows, 
each bearing a bulbous tixn)ed glandular hair; the head is iiale sere-brown (burnt sienna), with 
six whitish spots arranged in two vertical rows. The clypeus and labi’um are whitish. The 
first thoracic, first, third, and eighth abdominal segments each bear two large high dorsal warts, 
which are dark at the tips; they are fiauked by subdorsal and lateral Avarts which are but a 
little smaller; the dorsal ones in question are much larger and higher than those on the other 
segments, and the segments themselves are a dull xiale cherry-red. Thoracic segments 2 and 3 and 
abdominal segments 2, 4, 7,0, and 10, together Avith tlie tubercles, are bright yelloAv. The legs 
are all pale, though the anal ones are darker and redder. The glandular hairs are still bulbous 
in this stage, rather short and ev^en; those on the first thoracic and first, third, and eighth 
abdominal segments being longer than those elsewhere. 
These hairs are seen under a i-inch objective to be unusually large, distinctly tlattened at 
the end, Avhich is broad and square, the tixis being fiattened and transparent. In a fcAv of 
the hairs the exx^anded tix) apxiears to be ragged and broken, or toothed, and in one case 
deexfiy forked. 
The descriptions of the following stages are druAvii u]) from .Air. Bridgham’s excellent colored 
figures, those of the two earlier stages having been comxiared Avith my descriptions and found to- 
be accurate in form and color. His exanqiles of Stage 1 (from eggs I sent him) were draAVU July 
3 to 7; of Stage II, July 12; of Stage 111, July 18; Stage IV, July 23; Stage V^, and last, July 28.
