434 Report oF THE HorRTICULTURIST OF THE 
GRAPE INSECTS. 
CANE BORER. 
(Amphicerus bicaudatus Say. ) 
A small cylindrical beetle, which works as a borer in its mature 
stage. It injures the grape by burrowing into the stems in spring 
near the base of the new growth. It breeds in the dying wood. 
The larva sometimes feeds upon the grape vines. 
Treatment.— As it breeds in the dying wood, careful cutting 
away and destroying of such wood will help to check the insect. 
GRAPE-VINE FLEA-BEETLE. 
([altica chalybea Il.) 
Description.— The adult insects are shining steel-blue flea- 
beetles measuring about one-fifth of an inch in length. They live 
during the winter under the bark of the old vines or in rubbish in 
the fields. They emerge from their winter quarters during the 
first warm days of spring, and feed upon the opening buds and 
young leaves. Egg laying begins late in April or early in May. 
The eggs are placed singly near the buds or upon the leaves and 
hatch in about ten days. The young larve are dark brown in 
color but soon become prominently marked with black dots and 
patches. They are full grown in from three to four weeks at 
which time they measure about a quarter of an inch in length. 
They feed on the leaves, devouring only the soft parts at first, but 
finally eating irregular holes through the leaves. When ready 
to pupate they go a short distance into the ground. The adults 
emerge from these pupex during the latter part of June or early in 
July. They probably feed during all of the summer, finally seek- 
ing shelter for the winter as above indicated. 
L'reatment.— The vines should be sprayed with Paris green, 
one pound to fifty gallons of lime and water, just before the buds 
begin to swell. Much pains should be taken to make this appli-
