no. i. BOMBYCINE MOTHS OF NORTH AMERICA— PACKARD. 39 



The spines are short and stout, acute, and directed backward, but not curved; all the dorsal 

 spines on both thoracic and abdominal appendages of uniform size and shape, and all black. 

 The median spine on eighth abdominal segment is no longer and but httle larger than the others, 

 and either deeply or slightly forked. Infraspiracular spines conical, short; those on the second 

 and third thoracic segments over the base of the legs conical and as high as broad at the base. 

 The spines are about half as large as in Nudaurelia. 



The segments almost entirely covered with bluish green or pearly warts, usually densely 

 crowded above and on the sides, and covering the under side of abdominal segments 1, 2, 7, 

 and 8. 



Suranal plate with some warts at base, and anal legs with three on each side at base. The 

 plate is of nearly the same shape as in Nudaurelia (N. waMbergii and dione), but a little more 

 rounded behind than in N. waMbergii and with more distinct though minute setiferous tubercles 

 or warts. 



Body black; a median row of irregular black spots and a similar row on each side, a spot 

 to each segment. It varies in the crowded condition of the pearly fungoid warts; in one of the 

 three examples they are scattered and much fewer in number. This is 60 mm. long, but last 

 stage, as head is same width. Natal; Lieut. Col. J. M. Fawcett. [C. Oberthiir (Etud. Lep. 

 Comp., IV bis, 1910) discusses this species, as Nudaurelia belina, with good photographic figures. 

 He distinguishes a new variety junodi.]

Imago. — One 9 . Head, 9 antenna? and palpi as in A. belina, though the 9 antenna? 

 have longer vestigial branches. The fore wings a Httle more acute; outer edge a little more 

 excavated, the wings being subfalcate; hind wings of the same shape as in A. belina. It differs 

 from A. belina in the lines and ocelli, the ground color being uniformly of a peculiar elk gray. 

 Fore wings: Basal line very different from that of A. belina in being nearer the insertion 

 of the wing, and being much curved outward; brown, edged externally with whitish. Extra- 

 discal line as in A. belina, but more scalloped, especially toward the costal edge; ocellus less 

 D-shaped (7 by 5 mm.) and more completely circular; formed of a round circular black ring, 

 and an elk-gray broad ring between this and the central clear spot, which is D-shaped, just as 

 in A. belina; outside of the black circle is a broad gray ring, and still farther outside a narrow 

 white ring, interrupted in front and behind. 



Hind wings elk gray, with a much larger discal spot and rounder than in A. belina (20 

 by 19 mm.), and the black ring is nearly square (19 by 19 mm.) inside, not being regularly oval, 

 cylindrical, as in A. belina, while the center is not so yellow, being more of a fawn color, but the 

 central clear space is narrower. Extradiscal line not so heavy as in A. belina, and situated farther 

 from the ocellus. The pale pinkish middle of the whig inclosing the ocellus is deeper in tone 

 than in A. belina. 



Underside of the wings much as in A. belina, but the common extradiscal line is much more 

 scalloped than in A. belina. 



Expanse of fore wings, 9 120 mm. 



Length of one fore wing, 9 62 mm. 



Breadth of one fore wing, 9 35 mm. 



Length af hind wing, 9 42 mm. 



Breadth of hind wing, 9 35 mm.
