while the legs are light gray. The fore wings are "marked by heavy 

 white areas near the anterior margin and with a broad, oblique 

 white stripe on the posterior margin near the extremity. The hind 



wings are light gray, merging

 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 

 round 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 larvae 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 larvae 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 larvae 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 in an out-of-doors rearing shelter. The beginning of pupa- 

 tion was readily observed, since the larva pupates within the folded 

 leaf in which it undergoes the final molt.
