The female puparium resembles that of _C. aspidistræ_ (Signoret) and _C. populi_ (Bärensprung), but the abdominal segment of the female differs from both.
23. Chionaspis dysoxyli, Maskell. N.Z. Trans., Vol. XVII., 1884, p. 22. (Plate VI., Fig. 3.)
Female puparium thin, flattish, pyriform, white in colour, with a faint pink tinge when the egg-mass beneath shows through it; length, about 1/12in. The second pellicle is comparatively large.
Male puparium white, narrow, carinated; length, about 1/36in.
The insect affects principally the leaves of the plant, and the puparia are usually clustered thickly along the midrib.
Adult female yellowish-red, elongated, segmented; but not very deeply. Abdomen ending in a broken curve, with many curvilinear incisions. There are fourteen lobes, of which the two median are the largest; separated from them by a spine on each side are two others rather smaller; then another spine and a short open space; and then three smaller lobes and another spine; another space, and then a single small lobe, followed by a spine. Five groups of spinnerets: lower pair with twelve to fourteen orifices; upper pair with seven to ten; uppermost group, four to six. A few spiny hairs are on the edge of the abdomen.
Habitat--On _Dysoxylon spectabile_ (Kohe-kohe), Wellington; Hawke's Bay; Auckland.
The large white puparia of this insect do much to spoil the appearance of Dysoxylon, one of the most showy-leafed plants in New Zealand.
24. Chionaspis minor, Maskell. N.Z. Trans., Vol. XVII., 1884, p. 33. (Plate VI., Fig. 4.)
Female puparium white, small, not more than 1/15in. in length, usually less; it is narrower and less pyriform than is usual in the genus, and is often bent in the middle; pellicles yellow.
Male puparium white, narrow, elongated, carinated, about 1/30in. in length.
Adult female elongated; segmented, but not deeply; colour, dark-brown. Abdomen ending in six small lobes, of which the two median--the largest--are closely contiguous. Between them and the next pair is a spine; then beyond the second pair another spine, a space, and a third pair of very small lobes; after a long space there is another spine. Five groups of spinnerets: uppermost group with twelve to fourteen orifices; upper pair, fourteen to seventeen; lower pair, eighteen to twenty-four: many single spinnerets.
