each of which one or more brown hairs arise. By the middle of 
May they have attained full size. 
Pupation.— When ready to pupate the larve leave the vines 
and enter the eround to a depth of 2 or 3 inches to trans- 
form to the pupa state. The adults appear during the latter part 
of June or early in July. 
The adults— The adults feed all summer, finally sealemnes a 
refuge in which to pass the winter and coming forth in the 
spring in time to attack the buds as previously indicated. Proba- 
bly some of the adults lay a few eggs during the summer for both 
larvee and eggs were occasionally found last season as late as July 
14. The larvee varied in size from newly hatched to nearly full 
grown. 
METHODS OF COMBATING. 
Numerous remedial measures have been suggested and some of 
them tried. They include scattering air slaked lime or unleached 
ashes about the base of the vine to kill the larve as they attempt 
to enter the ground, spreading sheets of cloth saturated with 
kerosene oil on the ground under the vines and jarring the beetles 
upon them, and spraying the vines with kerosene emulsion or an 
arsenical poison to kill the larve. 
Spraying with an arsenical poison.— The Stina and thorough 
application of an arsenical poison is probably the most effectual 
and practical method of controlling this insect, especially in large 
vineyards. Paris green is usually used. It is not improbable 
that arsenite of lime would be equally effectual and cheaper. If 
Paris green is to be applied, use 1 pound to 50 gallons of water 
with the addition of enough freshly slaked lime to make the mix- 
ture milky in appearance. Make the first application a short time 
before the buds begin to swell or as soon as the beetles are found 
on the vines. The object of this first application is to cover the 
buds with poison so that the beetles whick eat into them will be 
poisoned by the Paris green. It will usually be found necessary
