Moth. — Two (5,19. Oclierous yellow and roseate. Head and body rosy Y)ink. Base of the 

 foie wings roseate, bounded externally by u pink line bent at a right angle upon tbe tirst anal vein 

 (VI). Between this line and the outer one the wing is oclierous yellow; outer edge of the wing 

 l)ink. Iliiul wings white, either unspotted or with a pink line along the edge; a slight pinkish 

 diseoloratiou at the internal angle. Abdomen roseate at the end. The legs are tinged externally 

 with roseate. Length of body, 15-20 mm.; exi)anse of wings, 36 mm. 



The young were reared from eggs kindly sent me .Tune 20 by Miss Emily L. Jlorton, of New 

 Windsoi', N. Y. 



Larva, tituge I. — Length, 2.5 mm. The head is very hirge 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 Jiear the vertex. On the xnothoracic segment are two rather large acute conical dorsal 

 tubercles of the same color as the head and larger than those on the first or eighth abdominal 

 segments, though all the dorsal tubercles on the body are unusually large, larger in in'oiiortiou 

 than in the tirst stage of Schizura; those on the second and third thoracic; segments are well 

 developed, but considerably smaller than those in front. Those on the hrst abdominal segment 

 are situated clcse together, while those on the first thoracic segment are rather wide ajjart. The 

 two oil 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 ]iosterior 

 thoracic segments being longer than those in the middle of the body, or in the allied genus 

 Schizura. 



The body above pale 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 with red. All the dorsal abdominal tubercles are quite large, 

 those oil the first and eighth segments scarcely larger than those on the other segments. The end 

 of the body is uplifted, both when walking and at rest. All the abduminal legs are reddish, and 

 the thoracic legs are dark. 



Utaye II. — .Just molted, July, ISDL Evidently delayed in its growth. Length, () mm. Head 

 moderately large (now wider than the body, as the larva has not begun to feed); it narrows 

 slightly above, and bears on the vertex two piliferous warts which are somewhat larger than 

 those below on the face, of which there are live, rather large conical warts, arranged in two rows, 

 each bearing a bulbous tipped glandular hair; the head is pale sere-brown (burnt sienna), with 

 six whitish spots arranged in two vertical rows. The clypeus and labruiu 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 flanked by subdorsal and lateral warts which are but a 

 little smaller; the dorsal ones iu question are much larger and higher than those on the other 

 segments, and the segments themselves are a dull pale cherry-red. Thoracic segments 2 and 3 and 

 abdominal segments 2, 4, 7, 9, and 10, together with the tubercles, are bright yellow. The legs 

 are all pale, though the anal ones are darker and redder. The glandular hairs are still Inrlbous 

 ill this stage, rather short and even;, 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 flattened at 

 the end, which is broad and square, the ti^js being flattened and transparent. In a few of 

 the hairs the expanded tip appears to be ragged and broken, or toothed, and in one case 

 deeply forked. 



Thede.scriptious of the following stages are drawn ui) from Mr. Bridgham's excellent colored 

 figures, those of the two earlier stages having been compared with mj- descriptions and found to^ 

 be accurate in form and color. His examples of Stage I (from eggs I sent him) were drawn July 

 3 to 7: of Stage II, July 12; of Stage III, July IS; Stage IV, July 23; Stage V, and last, July 28.
