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

 obtained. Of these the first emei-ged 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 larvae collected under these bands.

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

 last on September 24, The second-brood larvas wore few in number, 

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

DESCRIITION OF LOCALITY. 



The orciiurd at Pickens iji which banding records were obtained in 

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

 3,o00 fecit above the level of Ihe sea. The nal-ive lloi'n aiul fauna of 

 the inmiediate locahty indicate the junction of the Transition and
