only a few of the mature bags remained among the curled and torn 

 leaves on which they had developed. Occasionally throughout the sum - 

 mer a specimen would be met with, as often on the foliage of any other 

 tree as on maple, but there was no second brood. This species, unlike 

 Capsus oblineatus, is never to my knowledge found on flowers. It prob- 

 ably secretes itself early in the season and becomes dormant until the 

 following spring. 



The only remedial applications experimented with were Pyrethrum 

 powder and air-slacked lime, both of which were measurably effective, 

 judging by the small scale on which they were tried.
