Adult females enclosed in a sac, or test, of secretion so closely felted as to appear waxy; round the edge of the sac a double fringe of glassy tubes; apodous; antennæ absent. Anal tubercles present in all stages. The differences between this genus and _Asterolecanium_ (see above under _Lecanidinæ_) are not to be made out from external examination of the sac, nor without close investigation. It is possible, indeed, that _Asterolecanium_ should be removed from the _Lecanidinæ_ and united with _Planchonia_. 53. Planchonia epacridis, Maskell. N.Z. Trans., Vol. XIV., 1881, p. 224. (Plate XII., Fig. 2.) Test of adult female closely felted, smooth, hard, semi-transparent; flat beneath, convex above; elongated-oval, tapering towards the posterior end; completely enclosing the insect except at extreme posterior end, where there is a small orifice; colour partly green, partly yellow. Round the edge a fringe of long white glassy tubes in double row, one row over the other. Average length, exclusive of fringe, about 1/16in. Test of male unknown. Adult female filling the test, shrivelling at gestation. Antennæ absent, but represented by circular rings, each bearing four hairs. Feet absent. Anal tubercles small, setiferous. Anogenital ring inconspicuous, with six fine short hairs. Mentum uni-articulate; rostral setæ short. Round the edge of the body a row of figure-of-8 spinneret orifices; on the dorsal surface many circular spinnerets and a number of protruding tubes. Female of second stage elongated, flattish; colour, reddish-brown; length, about 1/20in. Antennæ absent, represented by rings, as in adult. Feet absent. Anal tubercles as in adult. Spinnerets and fringes as in adult. Young insect elongated-oval, tapering towards anal extremity, flat; anal tubercles clearly distinguishable, setiferous. Antennæ of five joints; the last joint clavate and bearing hairs. Feet normal; upper digitules fine hairs; lower digitales absent. Colour reddish-brown; on the dorsal surface many scattered figure-of-8 spinnerets, from which spring long, curling, white, glassy tubes. Length of insect, about 1/40in. Adult male unknown. Habitat--On _Leucopogon Fraseri_, Amberley and Sumner, Canterbury; on _Leptospermum scoparium_ (manuka) (sparingly), Nelson. A very pretty little species, resembling in outward appearance _Asterolecanium quercicola_, Signoret, but much smaller, and distinguishable by the presence of the anal tubercles. Genus: ERIOCOCCUS, Targioni-Tozzetti. Signoret, loc. cit., 1874, p. 29. Maskell, N.Z. Trans., Vol. XI., 1879, p. 218. Adult female enclosed in an elongated sac of white or yellow felted cotton; body elongated, segmented; anal tubercles conspicuous; feet and antennæ present; several rows of conical spines on dorsal surface. Antennæ of six joints.
