INVESTIGATIONS IN 1912. 



In 1912 the same orchard was used for the banding records as in 

 1911, although in most cases different trees were banded. Twelve 

 trees were used.

Table XXXIII indicates the numbers and dates of emergence of 

 > this brood of moths at Pickens.

Moths from the larvse that had wintered in the rearing jars did not 

 begin to emerge until nearly the middle of June, as is shown in the 

 table. The first were found in the jars on June 13, the greatest num- 

 bers from June 25 to July 3, and the last on July 17. 



BAND COLLECTIONS. 



Larvae were exceedingly scarce, as is shown in Table XXXIV, only 

 47 being taken under the bands during the entire season. The first 

 was found on July 24 and the last on October 5. The numbers are 

 so few that no distinct line can be drawn between the first and second 

 broods.
