Identification
Original description (Dyar, 1908, p. 98): Fore wing reddish ocherous, irrorate with blackish; costal edge blackish except where cut by the lines; discal spot large, blackish, sub-quadrate; lines ocherous, slightly intensified on the costa, strongly edged toward the median space with blackish, the inner slightly angled on median vein and produced inward on submedian fold, the outer mesially excurved obscurely dentate; a row of black points at the base of the fringe. Hind wing ocherous, reddish shaded, usually with an extra mesial dark line and row of dots in the fringe. Expanse, 16 to 23 mm. Allied to [Pyralis] constiferalis Walker, but the costal markings are not more developed than the cross-lines. Especially the basal costal mark does not exceed the subcostal vein, whereas in costiferalis it extends to the median vein.
