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 elongated, segmented; greenish-white; length, about
1/24in. Rudimentary antennæ visible. Abdomen ending with a median
depression, and inconspicuous lobes; several scattered spiny hairs.
Eight groups of spinnerets: four, containing each from twenty to thirty
orifices, are placed in opposite pairs, the fifth, with four to six
orifices, being between the upper pair; above these, three other groups
form an arch, the two outer ones having eight to ten openings, the
middle one three to five. Many single spinnerets.
Adult male of a bright scarlet or deep-orange colour. The antennæ,
covered with longish hairs, have ten joints, the first two very short
and thick; the next five long, equal, and cylindrical; the eighth and
ninth somewhat shorter; the tenth fusiform, and as long as the seventh.
The legs are rather long; the femur thick, the tibia more slender,
broadening towards the tarsus, which is about one-third as long as the
tibia, and narrows sharply down to the claw. Both tarsus and tibia are
hairy. The digitules are fine hairs.
Habitat--On _Veronica_, sp., and _Leucopogon Fraseri_, North Kowai
River, Canterbury; on _Cyathodes acerosa_, Wellington; on ferns, Napier.
Genus: FIORINIA, Targioni-Tozzetti. Uhleria, Comstock; 2nd
Entom. Rep., Cornell Univ., 1883, p. 110.
Female puparium elongated; first pellicle small, at one end; second
pellicle very large, entirely covering the insect, and almost extending
to the edges of the puparium.
Male puparium elongated; smaller and narrower than that of the female;
sometimes carinated; pellicle at one end.
Mr. Comstock proposes the name "Uhleria" for this genus, because
Professor Targioni, establishing his genus for the species to which
he originally gave the name of _Diaspis fioriniæ_, changed at the
same time the specific name to "pellucida." This, Mr. Comstock says,
necessitates now an entirely new generic name.
Targioni's nomenclature has been followed here, as likely to lead to
less confusion.

(Plate VI., Fig. 6.)
Female puparium elongated, flat, roughly pyriform or ovate, thin;
the secretion is yellowish-brown or dirty-white, but is scarcely
noticeable, on account of the second pellicle; length variable, from
1/12in. to 1/8in.; breadth, about 1/16in. First pellicle small, at one
end. Second pellicle, very large, almost filling the puparium, roughly
pyriform; abdominal region segmented; cephalic region large, oval;
abdominal segments tapering, exhibiting at the extremity either minute
serrations, floriated lobes, or tusk-like lobes, or a smooth curve;
the first abdominal segment sometimes produced into roundly-triangular
lobes.
