no. i. BOMBYCINE MOTHS OF NORTH AMERICA— PACKARD. 55 



The larva is a very remarkable one from the nature of the stout spines, and the forked median 

 spine on the eighth abdominal segment is a noteworthy feature. 



A genus differing from Bunaea in the longer, larger palpi, the nonfalcate, scalloped fore 

 wings, and the stouter body. The S antenna? are narrower, with shorter teeth. In its vena- 

 tion and shape of the discal cell it is closely similar to that of Nudaurelia (N. cytherea), and is also 

 intermediate between that genus and the Asiatic Salassa. In the small clear hemispherical 

 discal spot of the fore wings it approaches Salassa.

Imago. — One <$ , two 9 . Head and thorax Vandyke or chestnut brown; two white bands 

 behind the head, the second one, forming the hinder edge of the collar, the widest one of the 

 two. Fore wings grizzly chestnut brown, darker on the outer edge, crossed by four distinct 

 dark-brown hnes, and a fifth less distinct. Basal hne formed of two long scallops, being blackish 

 edged externally with grayish white, the black widening on the costa, the white toward the dis- 

 cal spot. The second line is scalloped and either (a small 9 from Amer. Mus. Nat. Hist.) inter- 

 rupted by the discal spot, or (in the 6" ) is situated just beyond it, sending a loop or scallop into it, 

 or in the large Durban 9 (like the one figured in Naturalists' Library) the line is farther out from 

 the spot. A second parallel similar hne is incurved near the inner edge on vein VII; both lines 

 widen on the costal and inner edges; beyond are two faint diffuse shades. The discal spot on 

 the fore wings is small, forming an incomplete ring, heavily black on the inside, then pink; the 

 outer side black where the extradiscal hne touches the spot, otherwise it (the Durban 9 ) is not 

 dark, the outer side of the subtriangular clear spot having no border. In the small 9 , however, 

 the irregular oblong clear spot is almost entirely surrounded by a pinkish oval circle. Outer 

 edge of both wings slightly scalloped, the interspaces grayish. 



Hind wings more scalloped in 9 than in c? , base and outer edge as in the fore wings, but a 

 large part of the wing is occupied by the very large ocellus, in which, however, the extradiscal 

 line does not enter. The spot is mostly bright pink, and the basal hne is pink. The center of 

 the spot is black, inclosing a half-round or lunate partly clear spot, a portion obscured by 

 dark-brown scales, so that the outline is more or less distinct. This black center is encircled by a 

 snuff-brown ring, this by a black ring, which is encircled by a very broad raw sienna ring, which 

 is surrounded by a broad pink (small 9 ) or a brick-red ( c? ), or dark blood-red ring (Durban 9 ), 

 beyond which is the dark-brown much-curved extradiscal line. 



Under side of both wings hoary gray, checkered with brown on the costa and brown on 

 the outer margin. The middle and extradiscal lines distinct. The discal spot interrupts the 

 extradiscal line, the clear space as above, but the inner brown side is wider and more distinct. 

 On the hind wings the discal spot is represented by the brown center and the umber-brown 

 and the outer narrow dark brown hne alone. No pink scales (small 9 ) ; in the Durban 9 the 

 umber hne is yellowish, so also in $ .
