spicuous ones on the edge. Extradiscal line not scalloped, but composed of a series of light 

 fawn-colored linear spots almost crescentiform in shape. Beyond is a broad diffuse dusky 

 shade, with the edges indistinct and irregularly scalloped. 



Hind wings much as in S. megastica, but the discal spot is a true ocellus, the naked though 

 not transparent irregularly oval center situated in a black field encircled by a rather broad 

 white line, and this by a deep Venetian red ring, outside of which is a clear fawn area, becoming 

 widest toward the costa, the whole enveloped in a heavy wide black ring forming a contin- 

 uation of the extradiscal line, which is composed of sublimate linear fawn spots. Two outer 

 dusky indistinct lines. 



Under side of both wings deep fawn brown inside of the common extradiscal line composed 

 of elongated white lunules; beyond paler, more reddish brown, and the edge of the wing darker, 

 the boundary line between these two shades being zigzag. Discal spot of fore wing as above ; 

 that of the fore wings a simple small naked spot, irregularly oval, and not quite so large as that 

 on the fore wing.

Imago. — d 1 (?). Head, femora, thorax, abdomen, and wings deep orange red, thorax a 

 little redder than the abdomen ; antennae black brown. 



Fore wings deep reddish orange, with darker scales and darker toward the outer edge ; a 

 basal regularly curved broad diffuse frosty gray line nearer the base of the wing than the discal 

 spot. Extradiscal line parallel with the outer edge of the wing, scalloped; it is situated much 

 nearer the discal spot than the edge of the whig. Discal spot comma-like, with a pale fine 

 whitish blue line around it, which is interrupted on the outer side, and which is filled in with 

 dark-brown. A triangular frosty white apical spot. A broad dusky brown submarginal 

 shade, with the edges scalloped. 



Hind wings with a discal spot similar to that on the fore wings but larger, rounder, and 

 the pale bluish white line is more complete. This ring is edged with black, and the spot is 

 encircled by a broad deep orange red ring, beyond which is a broad blackish circle, obsolete 

 on the hinder side, very wide and heavy on the costal side, where it is lined externally with 

 white; this outer ring is a continuation of the extradiscal line. Between this and the outer 

 edge of the wing are two dark reddish shades, the outer a narrower zigzag line, losing its zigzag 

 character toward -the costa. 



The under side of the wings of both pahs is more uniformly chestnut in color and frosted 

 over with white scales. The discal spots have a singular pale greenish glazed tint, with no rings 

 around them. The extradiscal line is common to both wings, that of the fore wings straight, 

 that of the hind wings much curved, ending at the middle of the costal edge, but not reaching 

 the costa.

Length of fore wing, 72 mm. 



Breadth of fore wing, 37 mm.
