An Account of the Insects Noxious to Agriculture and Plants in New Zealand: The Scale Insects (Coccididae)
Maskell, William Miles
Insects -- New Zealand; Scale insects
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.
Adult male unknown.
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.
Adult male not known.
Habitat--On _Parsonsia_, Hawke's Bay; on _Rhipogonum scandens_
(supplejack), Wellington; Canterbury; Otago.
The small puparia and the contiguous abdominal lobes of the female
distinguish this species.
Genus: POLIASPIS, Maskell; N.Z. Trans., Vol. XII., 1879, p. 293.
Female puparia elongated; pellicles at one end. Male puparia narrower,
elongated, pellicle at one end. Female with more than five groups of
spinnerets; abdomen without fringe.
In the kindred genus, _Leucaspis_, Targioni-Tozzetti (Signoret, loc.
cit., 1868, p. 101), the abdomen has a continuous fringe of long
spines, and the groups of spinnerets vary in number from five to eight.
25. Poliaspis media, Maskell.
N.Z. Trans., Vol. XII., 1879, p. 293.
(Plate VI., Fig. 5.)
Female puparium white, elongated, pyriform, slightly convex; length,
about 1/18in.
Male puparium elongated, narrow, white, doubtfully carinated.
