In the freshly hatched larva the black dorsal or heart line is heavier and more distinct than 

 in the larva at the end of this stage. 



Cervical plate of the prothoracic segment gamboge-yellow, the front edge around each sub- 

 median tubercle whitish. 



The hairs above are brown-black, while low down on the sides of the body, on the head and 

 prothorax, they are whitish. 



The dorsal setae are rather stout, with slightly marked short spinules, while the setae of the 

 lateral tubercles (supraspiracular and infraspiracular series) are slenderer, with longer delicate 

 spinules, and longer than in Telea polyphemus, stage I, being about three times as long as the 

 tubercle itself. 



Larva. — Fully grown. June 18, 1901. Length 75 mm. Of the size and general appear- 

 ance of Telea polyphemus, but the segments are not so angular and distinct. Head large, 

 rounded, nearly one-half as thick as the body, smooth, with pale hairs of uneven length in front 

 upon and on each side of the clypeus ; green a little darker than the body, which is of a delicate 

 pea-green, the hue of the underside of oak leaves. 



Prothoracic segment lunate, the cervical plate yellowish on the front edge, and behind 

 greenish yellow. A few minute hairs on the front edge, but no warts, except a small 3-setiferous 

 dark green flattened one low down on each side of the same segment. Second and third thoracic 

 segments decidedly convex, the two dorsal tubercles, one on each side, fleshy, cmite distinct, 

 giving rise to two or three long black hairs, and four short, rather sharp stout setae; the two 

 tubercles are connected by a dark dusky shade. There are similar but smaller tubercles on 

 the first and second abdominal segments with six straw-yellow hairs arising, two in a line across 

 the segment, one dark one on each tubercle, and three or four spines. On abdominal segment 

 3-9 the tubercles are nearly obsolete, bearing only one or two hairs. While the dorsal and supra- 

 spiracular lateral tubercles are green and of the same hue as the body, those of the lowest infra- 

 spiracular row are turquoise blue; two on the side of the second and third thoracic segments, 

 the lowest being situated just above the base of the legs. 



On the side of the second and third thoracic segments, just above each spiracle, is a conical 

 metallic polished silvery smooth tubercle, each bearing a slender black hair ; the tubercle on the 

 second segment is a little larger than the one behind it. 



The skin is dorsally and on the sides covered with scattered minute clavate whitish setae, 

 as usual in the larvae of this family. 



On the eighth abdominal segment is a small but distinct tubercle, with two or three spines 

 on each side, showing its double origin. The yellow hairs are about one-third as long as the body 

 is thick. Spiracles pale yellowish testaceous. A lateral whitish yellow line just above the spira- 

 cles and slightly edged above with livid or liver brown; on the eighth abdominal segment the 

 liver-colored brown predominates, and becomes the very distinct livid brown of the edge of the 

 suranal plate and sides of the anal legs. The thoracic legs are pale, the abdominal ones all 

 green except the anal in part; the abdominal legs bear on the sides black and white hairs. 



Cocoon. — Regularly oval, no stalk, the surface like that of Bombyx mori; a large opening in 

 front; color a rich greenish yellow. Length 43 mm.; thickness 22 mm.

Plate XXVII. 

 [Saturnia pernyi Guerin, Rev. Zool., 1855, pp. 6, 297; PI. 6, fig. 1.] 



The tip of the male antenna? of A. pernyi and yama-mai end in a simple point, with rudi- 

 mentary pectinations, more so than in T. jwlyphemus. 



The fore wings of 9 are less falcate than in A. yama-mai. The dislocated basal band is 

 redder than in A. yama-mai, and the extradiscal band is distinctly red, while that of A. yama-mai 

 is dusky brown, and the band beyond is distinctly white, while the same portion of the band in 

 A. yama-mai is narrower and pinkish. The ocellus on the fore wing of <? has a large round clear 

 space, while in d 1 A. yama-mai it is small and narrow oval; in 9 the clear space is rather small 

 and oval, while in 9 A. yama-mai it is large and round. In A. pernyi 9 the outer half of the
