(Plate XIV., Fig. 1.) Sac of adult female white, cottony, elongated, often aggregated in masses; length, about 1/10in. Sac of male similar, but much smaller. Adult female elongated-oval, convex, segmented; colour yellowish; anal tubercles brown, conspicuous. Length of insect, about 1/12in. Antennæ of six joints, with some hairs. Feet normal. Anogenital ring inconspicuous, with eight short hairs. On the edge of the body a row of conical spines (spinnerets). After gestation the insect loses its regular oval outline, shrivelling up at one end of the sac. Young larva and female of second stage similar to adult, but smaller. Adult male, "a delicate fly-like creature, with two large wings and a pair of long waxen filaments projecting from posterior part of the abdomen; these filaments are very conspicuous, being white, and longer than the body of the insect. Colour of body white, with many irregular markings" (Comstock, loc. cit.). Habitat in New Zealand--On _Araucaria excelsior_ (Norfolk Island pine), Governor's Bay, Canterbury. In America, on same plant. This insect is not greatly different from _E. buxi_, Signoret; but the sac differs, and there are a few distinguishing characters in the form of the antennæ and feet. 55. Eriococcus hoheriæ, Maskell. N.Z. Trans., Vol. XII., 1879, p. 298; Vol. XIX., 1886. (Plate XIV., Fig. 2.) Sac of adult female white, cottony, irregularly elliptical, slightly convex, often aggregated in masses; frequently so covered with black fungus as to present the appearance of a minute gall. Sac of male white, convex, smaller and more elongated than that of the female. Adult female elongated-oval, convex, red in colour; length, about 1/30in. Body segmented, tapering rapidly to the posterior extremity; the cephalic segment occupying more than half the length. Anal tubercles conspicuous, apparently two, but on close inspection found to be four, brown in colour; two of them bear longish setæ; all the four are much corrugated and bear many short spiny hairs. Anogenital ring inconspicuous, with eight fine hairs. Antennæ of six short joints, tapering. Foot as if atrophied, the joints small and swollen; digitules all fine hairs. On the body are many small conical spines, which are most numerous on the last two abdominal segments. Larva free, active, red in colour, flattish, elongated, tapering to the abdominal extremity; length, about 1/50in. Body segmented; anal tubercles two, conspicuous, setiferous, with some short hairs. Antennæ of six joints; feet normal.
