 Head, thorax, and base of fore wing sordid whitish, the latter diffused 

 along costa to slightly beyond basal third ; tegula with a pale brownish 

 suffusion toward apex ; fore wing strongly irrorated with contrasting 

 black spots, especially along veins; in the light basal patch, slightly 

 below costa, a conspicuous black spot; beyond basal patch a transverse 

 dark fuscous dash, which does not reach costa and which rapidly fades 

 to a pale brownish ochreous, becomes stronger in color from middle to 

 apical third, where it is followed by sordid whitish or cinereous and 

 is narrowly diffused along costa to apex ; at middle of cell a conspicuous 

 though small black discal spot ; at end of cell a white discal spot edged 

 with black ; above and below the latter spot considerable black scaling 

 fusing with the brownish-ochreous shade; from apical third of costa, 

 around termen to inner margin a series of blackish dashes edged in- 

 wardly and narrowly with pale yellowish brown; whole surface of 

 wing somewhat lustrous and appearing predominantly gi'ay; cilia 

 light fuscous, darker basally. Hind wing shining grayish fuscous; 

 cilia brownish fuscous with a fuscous basal band. Legs ochreous-white

 pointed extension of the sacculus, the transverse arm a slender pointed
