Physokermes abietis(Geoffrey). This insect is alwaysfound on spruce (Abiesexcelsa). The scale isvery much like a Lecan-ium in general appear-ance. It may be lookedfor on the younger twigs of spruce, and more especially in the forkings of the young twigs (fig. 215). The colour, generallya dull chestnut, harmonises well with the food-plant, which may be ameans of protection against natural enemies. Newstead says he hashatched from this scale a chalcid parasite, Encyvtus scaurus, Walk.; a. Fig. 215.—Scales 0/Physokermes abietis as found in theforkings of the young twigs of common spnwe. 229 small beetle, Brachytarsus varius; and a small dipteron, Diplosisledibulorum, Winnz. The life-history somewhat resembles that of a Lecanium, but the ana-tomical structure is altogether different and quite unique. Newsteadsays the eggs may be found in the pouches at the beginning of June,and the larva? hatch towards the end of July. This observation wasmade in Cheshire, and therefore differs from notes I have made herein Northumberland—viz., to the effect that on August 2, 1900, Ifound eggs, and on September 1, same year, I also found eggs, andplaced the insect containing them in a small box, but the observationwas neglected until September 21, when the larva? from those of thelatter date which had hatched out were all dead. The larva? hidethemselves rather effectually on the young twigs during the wintermonths. Hitherto no males have been found. The
