TORTRIC/D.£—PEROi\'EA. 221 



hollowed in the middle ; a conspicuous tuft of erected scales 

 in the middle of the disk. 



Antennas slender, blackish-browu ; palpi uplifted and con- 

 spicuously porrected, pale brown or white above, darker 

 brown beneath ; head and thorax brown, white, yellow, 

 orange, or otherwise in some degree of agreement with the 

 fore wings; abdomen rather flattened, pale brown. Fore 

 wings very gracefully shaped, moderately broad, the costa 

 dilated and very highly arched at the base, faintly hollowed 

 in a long curve in the middle, and again slightly arched 

 towards the apex, which last is somewhat pointed ; hind 

 margin beneath it faintly retuse ; dorsal margin straight and 

 full toward the base ; on the disk immediately before the 

 middle is a tuft or button of conspicuous raised scales placed 

 perpendicularly ; colour of the wings excessively variable — 

 brown, brown-black, purple-brown, chestnut, orange-red, or 

 any intermediate shade, either uuicolorous, or in the darker 

 shades having a white or orange stripe along the entire 

 dorsal margin, or an orange-red or chestnut similar stripe 

 from the base through the middle of the wing, or else along 

 the costal margin ; or mottled and blotched with white 

 stripes below the costa ; or broadly blotched from the base 

 with snow-white and spotted or dotted throughout with the 

 same ; or with an elbowed stripe of paler colour across the 

 basal area ; or any possible combination of these colours and 

 markings ; the discal tuft or button black or white, brown or 

 orange, either agre?ing with the general colour or strangely 

 contrasting therewith ; toward the hind margin is usually a 

 partial line of black dots, or sometimes white, these often 

 furnished with minute raised scales. Hind wings ample, 

 pale smoke colour, but silky. Female similar, apparently in 

 all modifications. 



Underside of the fore wings shining lead colour, faintly 

 dotted with white on the costa toward the apex. Hind 

 wings smoky white.
