two tons per acre, and may continue to yield good crops for from 
ten to fifteen years. By November the willow whips are ready 
to cut, the old stubs being left to produce the next year’s crop. 
It is the object of the grower to produce a tall, straight but 
flexible growth about one-cighth of an inch in diameter at base | 
and measuring from five to nine feet in height. The injury 
caused by the beetles is not so much the weakening of the plant 
by loss of foliage as by the branching of the willow whips which | 
results from the injury to the rapidly growing tips. The beetles 
which have lived over winter are astir early in May and feed for 
two or three weeks. They attack the young willows vigorously, 
feeding largely on the new growth, thus causing the tips to wilt 
and die. Frequently the entire tip is eaten off. In this manner 
irreparable injury is caused at the beginning of the season. Plate 
XVIII is from a photograph showing a bunch of young willows 
with injured tips. Plate XIX is from a photograph of a normal 
willow whip, and one which was injured early in the season in a 
manner similar to those shown at Plate XVIII. Ata the willow 
was eaten off or sufficiently to stop the growth, thus resulting in 
the sprouts and consequent worthless willows, as these sprouts 
never become long enough for basket-making purposes. The un- 
injured willow is shown on the left. 
The injurious work begun by the beetles is continued by the 
larve and adults of the next brood, and as these are much more 
numerous and appear at a time when the willows are growing at" 
their best, the injury is much greater.

DESCRIPTIONS AND LIFE HISTORY. 
Appearance in the spring.— The beetles which have lived over 
winter come forth from their retreats during the latter part of 
April or early in May. In the vicinity of Syracuse they are 
usually first seen from the 1st to the 10th of May. As pre-
