Moths from hand record larvse. — In all, 5,320 larvae of the second 

 brood were collected systematically from banded trees in orchards 

 and kept in cages in order that records might be obtained on emerg- 

 ence of moths from such sources. From the total larvse secured 

 in this way there emerged 3,848 moths, thus showing that 72.34 per 

 cent of the larvse under observation proved to be transforming larvae. 

 These records are shown in Table XIX.
