A very dark, only slightly preapical pm line separates a median area heavily suffused with lilac grey from a much darker brown to almost black post median area. The pm line is slightly concave and almost reaches the midpont of the inner margin. The cell marking is subrectangular, dark, and is marked with a small white dot near its center.

A. inornata lacks the white hairs at the base of the forewing.

ECLOSION, SCENTING AND MATING:

Females extend a scent gland from the tip of the abdomen. Males use highly developed antennae to track the airbourne pheromone to locate the females.
