Secretion of female white, thin, felted, formed of thin threads excreted from the numerous prominent spiny spinnerets, the threads becoming more or less matted over the dorsal surface. At the edge each thread corresponds to a spine, but has not the feathery form exhibited in the next species, _E. spinosus_, being more tubular. On the adult female the covering is often not to be detected, or presents only fragmentary portions; it is best observed on the female of the second stage. Secretion of the male pupa white, felted, thick, covering the insect all over, and exhibiting at the edge a small fringe. At first sight the test, being obscurely segmented, presents somewhat the appearance of a Dactylopid. Length of the felted mass, about 1/16in. Larva normal, flat, elliptical, active, exhibiting the usual abdominal cleft and lobes. Dorsal surface covered with spines, excreting a thin white mass of tubes and a tubular fringe. Female of the second stage more or less elliptical, slightly convex, brown in colour beneath the thin white felted covering, which usually presents a segmented appearance, due to the transverse rows of prominent spinnerets. Body covered thickly on the dorsal surface with spines, which are subcylindrical, the ends rounded, springing from tubercular bases. On the ventral surface many smaller spiny hairs. Abdominal cleft normal, the lobes large. Mentum probably monomerous: the tip bears several hairs. Antennæ of six somewhat hairy joints. Feet with rather large femora; the lower digitules are fine hairs. Anogenital ring bearing numerous hairs. Adult female elliptical, convex, hollow beneath, brown in colour, usually affecting the twigs and branches of the plant in preference to the leaves. Apparently naked, but on close inspection found to retain at least portions of the thin felted covering. Dorsal surface covered with great numbers of spines similar to those of the second stage; ventral surface with many small spiny hairs. Antennæ of seven joints. The feet have large coxæ and femora; the tibia is only about half as long as the tarsus; the lower digitules are only fine hairs. Adult male of normal form of _Lecanidinæ_: colour brown. On the head are six visual organs: two dorsal eyes, two ventral, and two ocelli. Antennæ reddish, ten-jointed; the second joint a good deal thicker than the rest, the second, third, and fourth joints the longest; the last three moniliform; all the joints hairy. On the five last joints are several hairs with knobbed extremities. Feet slender, hairy; digitules fine hairs. Abdominal spike short and rather broad. On each side of the base of the spike is a tubercle bearing a pair of longish setæ; each pair of setæ becomes enclosed in a long white cottony thread, and the two threads form conspicuous "tails," as is common with most males of the Coccid family.
