species; uniformly pale ochreous ; a single outer, broad, rather diffuse, dark- 

 ochreous, sinuate band nearer (lie margin than usual; more distinctly marked 

 at each end mi the inner margin and costa than in the middle. Fringe con- 

 colorous with the rest of the wing. Hind wings pale testaceous-whitish, with 

 a short, abbreviated, fuscous, geminate line on the inner angle, giving rise to 

 a transverse, nearly straight, ochreous line. Beneath pale straw-yellow ; the 

 lines re-appear Iteneat h. 



Length of the body, 3, 0.54, 9, 0.50; of lore wing, 3, 0.70, 9, 0.75; 

 expanse of wings; 1.50—1.60 inches.

This species differs in its larger size, stout, well-pectinated antennae, the 

 pale ochreous wings, without the usual strigse and discal dot, the uniform 

 straw-yellow wings, and the single, dark, ochreous, broad, rather diffuse, 

 slightly sinuate line; in the pinkish front and pectus, while the outer edge 

 of the wing is less sinuate than usual. It is mentioned on page 21 under 

 the name of Eurymene unitaria.

Head rather narrow in front; palpi long, ascending, extending well in 

 front of the head; male antennas very thick, not pectinated; in the female, 

 slender, simple. Fore wings unusually short and broad; costa fuller than 

 usual : apex rectangular: outer edge bent in the middle, deeply excavated on 

 each side of the angle in the female Hind wings rounded at the apex, with 

 a distinct angle in the middle, reaching as far as the end of the abdomen, 

 which is slender, ending in a long tuft. Hind tibiae much swollen; tarsi a 

 little less than one-half as long as the tibia'. Venation: but live subcostal 

 venules; no subcostal cell; costal vein anastomosing with the subcostal. 

 Posterior discal vein very oblique; the first and second median veins nearly 

 co-originating, not so remote at their origins as in Hyperetis and Plagodis. 

 Coloration: silvery-oc.hreous, with numerous brown, irregular, tine lines; the 

 veins brown, and the margin of both wings more or less suffused with ochre- 

 ous-brown.
