DESCRIPTIONS OF NEW SPECIES AND VARIETIES 



OF ARCTIID^. 



By Henry Edwards. 



EUPREPIA Opulenta. Hy. Ediv. n. sp. 



Primaries sordid white. At the extiemity of the cell, two 

 minute brownish dots, and beyond them a broken irregular brown 

 patch, and another at the extremity of the median nervule, 

 broken up into small irregular patches on the posterior margin. 

 Apex of the wings brownish. On the internal margin near its 

 posterior termination, are two brown triangular spots and a small 

 brown dot about the middle of the interior margin, resting above 

 the submedian nervure. Secondaries, scarlet with an orange 

 tint. On the costa, near the apex, is a small golden yellow blotch, 

 a circular spot of the same color in centre of the wing, and an- 

 other near the anal angle. There is also a small golden yellow 

 mark at the extremity of the cell. There are two submarginal 

 black spots, surrounded by a ring of golden yellow, the one near- 

 est to the costa being oblong, and the other circular. Beneath, 

 both wings are washed with scarlet, the primaries having 2 sub- 

 marginal black spots, and a median band of golden yellow. Apex 

 sordid white. Secondaries with a yellowish band on the costa 

 near the base, and the markings of the upper side, faintly re- 

 peated. Thorax above, brownish black, except its front, which is 

 scarlet. Patagia, whitish. Abdomen scarlet above and below, 

 imperfectly banded with black. Legs and under side of thorax, 

 dusky brown. 



Exp. of wings, 2.00 inch. 



I $ Yukon River, Alaska, 700 miles from the mouth. F. 

 A. Smith. 



Type. Coll. Hy. Edwards. 



A most remarkable and unique form. If a variation of any 

 species, I know not where to refer it, as it appears in some re- 

 spects to differ structurally from A. Caja. L. I know of no other 

 species of which it can possibly be a variety. It is extremely in- 

 teresting, not only for its beauty and its curious appearance, but 

 also from the locality of its capture. 



Arctia Incorrupta. Hy. Ediv. n. sp. 



Closely allied to A. Blakei, Grote, but differing from that 

 species by the presence of a distinct sub-basal band, broadest on 

 the costa, and running quite across the wings to the internal mar- 

 gin of the primiaries. The costa of the secondaries is rosy, and 

 the black marginal spots are clearly cut, 4 in number and not 

 confluent on the costal apex. There are no discal spots as in 

 A. Blakei, but the wing is rosy to the base. I have seen 6 or 7 

 examples of A. Blakei, and have found the costa of secondaries in 

 all of them rather broadly black, and the discal spots, 3 in num-
