SUMMARY. 
During the past four years the growers of basket willows in 
central New York ‘have suffered serious loss’ from the depreda- 
tions of the cottonwood leaf beetle. } 
In both the larval and the mature stages, the insect attacks the 
willows, feeding upon the young leaves and tender bark near the 
tips. This injury to the tips causes the willow “ whips” to 
branch, thus rendering them worthless for basket making pur- 
poses. | : 
It lives above ground during all of its transformations. The 
eggs are laid upon the leaves and the larvie feed upon the more 
tender tissues. The pup are attached to the under sides of the 
leaves or to the bark. The mature insects, beetles, are active and 
fly readily from one field to another. The winter is passed in the 
adult stage, the beetles seeking shelter under stones, logs or any 
‘convenient rubbish. | 
On the experimental field the willows were successfully pro- 
tected by three applications of green arsenite, 1 pound to 100 gal- 
lons of water.
