♂, expanse 2⅜ in.; ♀, 2½ in. Fore wings long, pointed, apices depressed, of a uniform pale, rather dirty yellowish colour. There is a row of short intravenular dashes which form a narrow blackish line from apex to inner margin close to thorax. In the females this is almost straight, in the males it has somewhat of a downward curve. Another row of somewhat sagittal-shaped spots forms a second dark band from apex to inner margin a little within inner angle. Hind wings yellowish, semitranslucent, inner third dusky. Discal dot small, black. These markings, while distinct, are not heavy or pronounced. Thorax a little darker than wings. Abdomen dusky above, anal tuft yellowish. Beneath as above, only fainter. Thorax, legs and abdomen same, except inner side of fore femora, which are somewhat orange. Palpi dusky at extreme tip. Antennæ dusky, narrowly bipectinate in ♂, broadly so in ♀. The ♂ has the dusky shades darker than in the ♀, the abdomen being quite dark blackish brown above, contrasting with the light anal tuft. Types 2 pair in my collection from Huachuca Mt., Arizona. I take pleasure in naming this species after Mr. Otho C. Poling, of Quincy, Ill., as a slight token of my appreciation of the many favours he has done me.
