previously explained. 
Hibernation — By the 1st of August nearly all the beetles have 
left the willows and sought shelter in any convenient place. In 
the fields about Syracuse they could occasionally be found under 
stones but were more numerous under logs, under bark on trees 
and in the crevices in fence rails. In willow fields which have not 
been kept free from weeds and grass, the beetles find shelter down 
close to the roots or in the stools of grass. In these retreats they 
remain until the following spring. 
NUMBER OF BROODS. 
There are probably two broods and possibly three, but this point 
has not been satisfactorily settled. The writer failed to find eggs 
later than June 24th, and as the beetles retreat to winter quarters 
early in August, there is hardly time for more than two broods 
under the most favorable circumstances. 
NATURAL ENEMIES. 
Several species of Coccinellidaé, lady-bird beetles, and Cara- 
bidaé, ground beetles, are said to attack this insect in the un- 
developed state. The eggs especially are devoured by the lady- 
bird beetles. Dr. Riley® states that he has observed a species of 
Coccinellidae, Megilla maculata, feeding upon larve and pupe of 
this insect. Doubtless these natural enemies have been more or 
less active in the willow fields about Syracuse, but the writer did 
not observe an instance of this kind on any of the visits to the 
fields, and of several growers questioned, none had seen the pre- 
daceous insects. 
METHODS OF COMBATING. 
The principal methods employed by the willow-growers of this 
State in combating the cottonwood leat beetle may be classified 
under two heads.
