The hind wings are light gray, merging into a somewhat darker gray at the outer margins. The adult was first described by Clemens in 1860. The fol- lowing is his description: Anchylopera nubeculana n. s. Fore wings white, with a dark brown dorsal patch extending from the base to the middle of the wing, with its costal edge irregular or doubly curved. The oblique central fascia is almost obso- lete, except on the middle of the costa, where it appears as a dark grayish brown roimd spot exterior to which is a short black dash. The wing above the inner angle is varied with grayish brown and brownish. The costa exterior of the middle is alternately streaked with white and brownish, becoming reddish brown toward the tip. Extreme apex reddish brown. SPRING PUPATION OF WINTERING LARV^. At Winchester, Va., in the spring of 1915, pupation of the winter- ing larvEe began the latter part of April, and from that time pupation appeared to depend entirely on the temperature, A few days of warm weather would result in several larvae entering pupation, while a cold spell would prolong that period for those already in pupation and prevent any additional larvse from transforming. In the latitude of northern Virginia and the District of Columbia pupation evidently begins normally about April 20, or possibly a little before, depending on the relative lateness of the season. The larvse used in obtaining these pupation records were collected in November, 1914, shortly before the leaves began to drop. They were placed in rearing jars partly filled with soil and carried through the winter i
