One o" , one 9 . Fore wings decidedly falcate, wings of both pairs yellowish green. Costa 

 of fore wings much curved, apex sharp, outer edge slightly scalloped. Costal gray, madder or 

 wine-red band unusually broad and spreading behind vein II at base of wing and also toward 

 the apex. Ocellus round, slightly ovate, the transverse diameter greater than the longitudinal, 

 the clear space a very narrow oval area or slit situated on the outer side of the discal vein, and 

 about one-third as long as the entire ocellus. An outer dark-brown ring, wide on the inner side, 

 very narrow on the outer, succeeded by a steel-blue narrow semicircle, followed by a dull reddish 

 orange-ochre semicircle, the outer edge of which is ochreous brown ; the innermost ring is fawn 

 brown, wide, and inclosing the clear area, and paler beyond than within the discal veins. On 

 the outer side between this and the outer ring the outer hemisphere of the ocellus is filled with 

 a delicate greenish yellow. The discal veins are unequally developed, the anterior one is thick, 

 ending before reaching the middle of the discal cell, while the hinder vein is very narrow, almost 

 obsolete. Extradiscal line situated near the ocellus, not continuous but broken, represented 

 by spots on the veins, being obsolete in the interspaces. A second parallel line beyond, obsolete 

 on the front half of the wing, but widening towards the hinder edge, and becoming several 

 times as thick as the extradiscal line. Edge of the wing scalloped with red brown; fringe 

 reddish brown; no submarginal line. 



Hind wings ending in very long narrow tails, longer than the rest of basal portion of the 

 wing; the tails are very narrow in the middle and widen at the end; grizzly red-brown on the 

 basal half, this shade extending up along the outer edge of the wing. Discal spot situated 

 unusually near the outer edge of the wing, rounder than that of the fore wing, the inner brown 

 circle smaller, but the clear area slightly wider. No bands on the hind wings except faint traces 

 of an oblique one at the base of the tail. 



Beneath, the venular spots are larger than above. Ocelli as above, but faded. 

 Body whitish, a lateral short broad brown band on each side of the abdomen. Side of 

 the head, legs, and palpi deep claret-red, legs white on the inside of the femora. 



Expanse of forewings, 6" 108 mm. 



Length of forewing, 6" 58 mm. 



Breadth of wing measured across ocellus, 6* 31 mm. 



Length of hind wing, 6* 100 mm.; to base of tail, 46 mm.; tail, 54. 



Breadth across ocellus, <? 32 mm. 



Ocellus of forewing 6 J by 5; of hind wing, 5£ by 6* mm.
