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; colour, pink. The abdominal segment
somewhat long, the edge broken by a number of deepish curvilinear
serrations, and ending in two inconspicuous median lobes, with three
others, much smaller, on each side. From the serrations spring some
hairs. There are five groups of spinnerets, but the three upper ones,
almost or quite conjoined, form a nearly-continuous arch, containing
forty to fifty orifices; the two lower groups have fifteen to twenty.
There are several single spinnerets. The adult insect, before
gestation, nearly fills the space covered by the second pellicle; after
gestation it shrinks up into very small compass at the cephalic end of
the puparium.
Adult male unknown.
Habitat--On _Brachyglottis repanda_; _Panax arboreum_, Port Hills,
Canterbury.
Differs from the European species, _F. pellucida_ (Targioni), in its
extremely-minute size, in the serrations of the abdomen, and the number
of its hairs. Also in _F. pellucida_ the young female larva has two
tubercles between the antennæ, which are not seen in _F. minima_.

(Plate VI., Fig. 7.)
Female puparium elongated, narrow, with sides almost straight and
parallel; length, about 1/11in.; breadth, about 1/50in. Colour of
secretion, white, but seeming black, as the second pellicle shows
through it. First pellicle, black, small, at one end; the cephalic
portion prolonged in a slightly-cylindrical form. Second pellicle,
very long, filling the puparium; black; entire for most of its length,
but at the abdominal extremity cut across by transverse divisions
forming narrow radiating segments; extreme edge semi-circular, sharply
serrated. Texture, horny, hard, and strong.
Male puparium elongated, narrow, like that of the female; length, about
1/12in.; colour white; pellicle, black, at one end; not carinated.
Some puparia, both male and female, are found slightly curved.
Adult female small, elongated, segmented; length, about 1/30in.,
shrivelling at gestation. Cephalic portion compressed, cylindrical.
Abdomen somewhat elongated, ending in a number of sharp-pointed,
triangular, tooth-like lobes, between which may be made out a few
(four?) very minute, roundly-triangular lobes. Five groups of
spinnerets, the three upper groups almost joined in an arch; in the
arch, forty to fifty orifices; in the two lower groups, ten to fifteen.
Adult male, brown. Antennæ, ten-jointed; each joint except the first
two long and hairy; on the last joint one hair longer than the rest,
and ending in a knob. Legs, slender; claw, very thin; digitules, fine
hairs.
Habitat--On _Dendrobium_, sp., _Hedycarya_, sp., Hawke's Bay; _Phormium
tenax_, _Cordyline australis_, _Astelia cunninghamii_, _Muhlenbeckia_,
sp., Wellington; Canterbury; Nelson.
Group II.--LECANIDINÆ.
