It will be seen from this table that only 41 first-brood moths were 

 obtained. Of these the first emerged on July 23, the maximum num- 

 ber on July 30, and the last on August 9. 



BAND COLLECTIONS. 



A period of cold, occurring April 20 and 21, when the temperature 

 dropped to 20° F., followed by another drop to 25° F. on the night 

 of May 10, destroyed practically all the apple crop in the locality. 

 One old orchard containing a few bearing trees that were not sprayed 

 was found and eight of the trees were banded on July 1. Table XXX 

 shows the number of larvse collected under these bands.

This table shows that the first larvse were found under the bands 

 on July 5, the greatest number, which was 19, on July 12, and the 

 last on September 24. The second-brood larvse were few in number, 

 the collections being nearly uniform from August 6 to 23, after which 

 time they decreased until the last was found. 



INVESTIGATIONS AT PICKENS, W. VA. 



DESCRIPTION OF LOCALITY. , 



The orchard at Pickens in which banding records were obtained in 

 1911 and 1912 is located in a mountainous region at an elevation of 

 3,500 feet above the level of the sea. The native flora and fauna of 

 the immediate locality indicate the junction of the Transition and
