FAMILY PHYLLOXERIDAE Members of this family resemble those of the family Aphididae but differ in that eggs are laid by both sexually perfect and im- perfect females. The majority of important eastern species feeds on the needles, twigs, limbs, and trunks or in galls on coniferous trees. The eastern spruce gall aphid, Adelges abietis (L.), an introduced species, occurs in southeastern Canada and the Northeastern and Lake States. Its preferred hosts appear to be Norway and white spruce, but it is also found occasionally on red and Colorado blue spruce. T

The following notes are the result of observations made on pine weevils and parasites collected in a plantation on the estate of Banchory Devenick near Aberdeen. The-plantation in question was formed in the spring of 1911, a year after the removal of the old crop which was a pure wood of Scots pine. The stumps and roots of this old wood afford ideal breeding places for the pine beetle {H. piniperda) and the pine weevil {Hy
