$ . — Fore wings broad, extended at apex. Hind wings small, narrowed, much 

 rounded. Front of dark brown, mixed with white scales. Head and thorax above 

 dark brown and ashen. Fore wings pale silver-gray. The basal line shaded out- 

 wardly with dusky runs straight across wing from costa, ending at inner margin 

 twice as far from base, the enclosed space paler than the rest of the wing. Intra 

 discal line is geminate, dark gray, waved, and runs straight across wing from costa, 

 about two fifths out, darkest at costa and on veins, preceded by a geminate pale 

 line. The extra-discal, a broad shade-line, -darkened on veins, starts from a square 

 dark gray patch on costa, curves slightly outward at cell, otherwise parallel to intra- 

 discal, the space between them pale. A subterminal dusky shade-line starts from 

 costa half way from extra-discal to apex, preceded by a geminate pale line, and is 

 sharply defined inwardly by a black wavy hair-line, parallel with extra-discal. 

 Outwardly to border, dark gray, centrally traversed by an ill defined whitish hair- 

 line. A black terminal line interrupted between the veins. Fringes dusky white. 

 Hind wings clear white, with narrow dusky marginal line. Discal dots faint points 

 on all wings. Abdomen and legs dusky white, the former with each segment nar- 

 rowly bordered with black on posterior edge. Beneath pale silver-gray, a few dark 

 scales costally on fore wings and the shade-lines above showing faintly. Discal dots 

 faint. 



The 9 is darker, more brownish, the lines well defined. The hind wings are 

 decidedly dusky, with a well marked geminate subterminal line, darker than ground 

 color of wing, preceded by a geminate pale line parallel with the strongly rounded 

 outer margin, which is darker, with the fringes long and dusky. Beneath darker 

 than in $ with the body browner, obscuring the black rings on abdomen above. 

 No discal dots on wings above or below. Expanse, 20 to 22 mm. 



The O from Pasadena, Calif. (Mar. 3, 1902) has been in my 

 possession nearly two years, through Mr. Geo. Franck of Brooklyn. 



The (j^ is a recent acquisition from San Diego Co., Calif. (Feb. 

 15, 1906) through my friend Mr. H. W. Marsden.
