Motli, — Two (5,19. Oclierous yellow and roseate. Head and body rosy pink. Base of the 

 fore wings roseate, bonnded externally by a pink line bent at a right angle upon the first anal vein 

 (Vl). Uetween this line and the outer one the wing is oeheroiis yellow; outer edge of the wing- 

 pink. Hind wings white, eitlier unspotted or with a pink line along the edge; a slight i)iukish 

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

 with roseate. Length of body, 15-20 mm.; expanse of wings, 36 mm. 



The young were reared from eggs kindly sent me June 20 by Miss Emily L. Morton, of Isew 

 "Windsor, N. Y. 



Larru, ,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 prothovacic segment are two rather large acute conical dorsal 

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

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

 than in the lirst stage of Schiznra; those on the second and tliiid thoracic segments are well 

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

 are situated close together, while 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 giandidar 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 posterior 

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

 Schiznra. 



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 on 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 abdominal legs are reddish, and 

 the thoracic legs are dark. 



t^tai/e II. — Just molted, July, 1801. Evitleutly delayed in its growth. Length, mm. Head 

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

 slightly above, and bears on the vertex two piliferons warts which are somewhat larger thau 

 those below on the face, of which there are five, 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 labrum are whitish. The 

 first thoracic, first, tliird, and eighth abdominal segments each bear two large high dorsal warts, 

 which are dark at the tips; they are fiauked by subdorsal and lateral warts which are but a. 

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

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

 abdominal segments 2, 1, 7, 9, and 10, together with the tubercles, are bright yellow. Tlie legs 

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

 in this stage, rather short aud even; those ou the first thoracic and first, third, and eighth 

 alxlominal segments being longer than those elsewhere. 



These hairs are seen under a A-inch objective to be unuNualiy large, distinctly fiattened at 

 the end, which is broad and square, the tips being flattened aud transparent. In a few of 

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

 deeply forked. 



The descriptions of the following stages are drawn uj) from Mr. Eridgham's excellent colored 

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

 be accurate in form and color. His examples of Stage 1 (from eggs 1 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.
