color, with the long scales tipped with fuscous. Abdomen cream 

 ochreous, slightly darker on top of each segment. Legs paler. 

 Fore wing pale creamy ochreous, or creamy white terra-cotta; 



there is a dull white, narrow hand from base, over lower vein of cell 

 nearly to termen; before middle of wing it begins to increase in 

 width, so that at outer end it covers all space between veins '2 and 7; 

 the lower part and outer end are overlaid with whitish fuscous; all 

 of the dorsal margin to above the fold is of the same shade. These 

 two whitish streaks are separated by a clear line of ground color; the 

 median white streak is outlined on both sides by blackish brown dots 

 and a line of the same limit the upper edge of the dorsal white shade. 

 Both of the white shades are interrupted by the subterminal line, 

 which is ground color; it cuts through the median at the end of cell 

 and the dorsal before the middle of wing. There is a broad band 

 of ground color before termen, divided by a parallel terminal line 

 of shining whitish scales thickly 

 dotted with brownish fuscous. At 

 the end of each vein, in the mid- 

 dle of termen, is a tiny black dot. 

 Cilia narrowly white at base, fol- 

 lowed by a narrow fuscous line, 

 then by a shining whitish line; 

 beyond it is white, thickly sprin- 

 kled with light brownish fuscous; 

 extreme tips of scales white. 



Hind wing light fuscous, with a 

 trace of a darker line before the 

 cilia; cilia white, divided by a darker line near base; underside the 

 same. Underside fore wing darker fuscous, finely atomized with 

 paler specks; the lines of the cilia are repeated from above.
