is but one brood each year, and the winter is passed in
the adult stage. The beetles appear the latter part of May and feed upon
the stems and leaf veins during the egg-laying period, which extends
from the last week in May up to August 1st. The eggs are laid in
irregular crescent-shaped punctures, similar to those of the plum
curculio, and hatch in from six to twelve days, depending upon the
weather.

From four to six weeks are necessary for the development of the larvae,
and when mature they go into the ground where they remain for about ten
days an inch or so beneath the surface. They then pupate, and from
sixteen to twenty days later the adult beetles emerge. They fly to the
trees and eat small holes chiefly at the base of the leaf petioles, but
must early go into winter quarters as they are seldom seen after the
first week in September.

This insect occurs throughout the Eastern United States, but seems to
cause more injury in Connecticut than has been noted elsewhere. The
remedy is to spray the new shoots and under side of the leaves about
June 1, with lead arsenate (6 lbs. of the paste in 50 gallons of water),
to kill the beetles when feeding on the leaf petioles.

THE NUT WEEVILS.

_Balaninus_ sp.

Several kinds of nuts are attacked and injured by long-beaked snout
beetles or weevils belonging to the genus _Balaninus_, the chestnut
probably being the most seriously damaged. All of them feed inside the
nuts or fruit during the larval stage, and the larvae are without legs.
As both the methods of attack and the life history are similar for all
species, they will be considered here in a group. For the sake of
distinguishing them, however, their names are mentioned.

Larger Chestnut weevil, _Balaninus proboscideus_ Fabr.
Lesser Chestnut weevil, _B. rectus_ Say.
Hickory nut or Pecan weevil, _B. caryae_ Horn.
Hazelnut weevil, _B. obtusus_ Blanch.
Common acorn weevil, _B. quercus_ Horn.
Mottled acorn weevil, _B. nasicus_ Say.
Straight-snouted acorn weevil, _B. orthorhynchus_ Chittn.
Sooty acorn weevil, _B. baculi_ Chittn.
Confused acorn weevil, _B. confusor_ Ham.
Spotted acorn weevil, _B. pardalus_ Chittn.

All of these weevils pass the winter in the ground in the larval stage,
transforming to pupae about three weeks before the adult beetles emerge,
which varies from June, when they are usually few and scattering, to
September, when they have become abundant. Thus there is a single broo
