no. i. BOMBYGTNE MOTHS OF NORTH AMERICA— PACKARD. 31 



Fore wings subacute at tip, apex not rounded; the ground color whitish ash, reddish on 

 the costal edge, especially beneath; the basal line curved, bent outward on veins III and V. 

 Extradiscal line sinuous, somewhat parallel with the outer edge and quite regularly scalloped, 

 the seventh scallop or point acute; all nearly the same size. Beyond are three or four parallel 

 faint wavy ashen or fawn colored lines on a whitish field; edge of the wing light fawn. Discal 

 ocellus round, slightly oval, moderately large (7 by 5 mm.) consisting of a black ring inclosing 

 a pale fawn area, the center of which is darker fawn, with white scales, densest on the inner side. 

 Hind wings cream-white; base of wing clear white; a faint extradiscal line nearly touching 

 the ocellus; it is sinuous and fades out toward the costa. Edge of the whig sparingly dusted 

 with dark scales. Ocellus about a third smaller than that on the fore wing (6 by 5 mm.), not 

 quite round, the dull ochreous ring is broader than in the ocellus of fore wing, and incloses a 

 brown center, with white scales on the inner side (no red scales as figured by Maassen). 

 Beneath as above, but fewer white scales in the ocelli. 



Abdomen; with reddish scales along the sides of the abdomen, forming a series of lateral 

 red spots. 



Expanse of fore wing, 9 100 mm. 

 Length of a fore wing, 9 50 mm. 

 Breadth of a fore wing, 9 27 mm. 

 Length of a hind wing, 9 35 mm. 

 Breadth of a hind wing, 9 28 mm. 

 The specimen in the Schaus collection of the American Museum of Natural History agrees 

 well with Maassen and Weymer's figure, but there are no red scales in the ocelli. 

 Geographical distribution. — Delagoa Bay (Schaus, Maassen).

Imago. — <? . Head rather narrow in front, which is triangular, narrowing more in front 

 as in Imbrasia, but a little more full and hairy; antennas with about 25 joints, broadly pecti- 

 nated, scarcely plumose, much as in Imbrasia, with two pairs of branches to a joint; the pecti- 

 nations long and slender, much ciliated .to near the tip, which is filiform, in the last five joints 

 in 9 subsimple; pectinations of both pairs triangular, tooth like, those of the distal pair about 

 one-third as large as those of the basal pair. Eyes moderate in size. Palpi small, weak, de- 

 pressed, almost invisible, not reaching the front. Body woolly, the wings thin-scaled. 



Fore wings moderately wide, rather small, subfalcate; costa somewhat curved toward 

 the apex; outer edge very slightly incurved behind the apex; outer and inner edge of about 

 the same length; apex moderately pointed. Hind wings in 9 with a pronounced angle (in 

 one 9 the wing is well rounded), the outer edge in front of the angle slightly excavated, behind 

 the angle straight. 



Venation: Similar to that of Imbrasia, but the origin of vein II [III, in revised nomen- 

 clature] and of the stalk of II 3 and II 4 are much farther apart; vein II, is absent; in the hind 

 wings the discal cell is wider than Imbrasia, vein III 2 originates nearer HI,, and the two discal 

 veins taken together form a straight line, not directed outward as in Imbrasia; vein III 3 ends in 

 the distinct angle. 



Markings: A triangular dark ash-brown discal spot, with a minute clear center situated 

 outside of the discal vein. Hind wings with a much larger dark smoky brown ocellus, round, 

 with a nearly clear center surrounded by a white diffuse broad ring. 



Geographical distribution. — Ethiopian region; Natal. 



This genus is allied to Imbrasia, as shown by the venation, the palpi and the antennae; 

 as well as the distinct angle of the hind wings. In the markings also the two genera closely
