It will be noticed that the curves illustrating the emergence records 

 follow closely the contour of the corresponding band-record curves, 

 as far as the first and the second broods are concerned. The third 

 brood is, of course, not represented in the emergence records. A 

 record of the emergence of the third brood of 1907 (spring brood of 

 1908) .is given on page 5, figure 1.

The ratio in size of the second brood of adults to the second brood 

 of larva? is practically the same as between the first-brood adults

 records, respectively. This shows that as large a proportion of the 

 second-brood as of the first-brood larva? transform to adults; which 

 is evidence that there is nearly a full third brood.

LARVAE ON FOLIAGE. 



Two larva? just hatched were inclosed in paper bags on water 

 sprouts May 4. The twigs were not examined again until May 29. 

 In each case there was evidence of work by the larva?. On one twig 

 the feeding was confined to a leaf, but on the other four the young 

 larva? had bored down the tender end of the sprout from half an inch 

 to 2 inches. No remains of the larvae could be found. They had
