SCALE-INSECTS. 83 
This insect belongs to Signoret’s fifth series. 
A European species, L. cycadis, Boisduval, is said by Dr. 
Signoret to closely resemble L. olew, the only difference ap- 
parently being the possession of nine-jomted antenne. This 
character is so exceptional in the genus that it perhaps may be 
bnt doubtful. 
Genus: PULVINARIA, Targioni-Tozzetti. 
Female insects naked, arboreal, constructing an ovisac. 
Male pup in cottony or waxy sacs.

(Plate XII., Fig. 1.) 
Adult female yellowish- or reddish-brown, naked, slightly. 
convex, elongated ; skin smooth, with puncta; length variable, 
.from about 4in. to din. Antenne (according to Signoret) with 
sometimes six, sometimes seven, joints. Abdominal cleft and 
lobes normal. The insect excretes a narrow, white, cylindrical 
cottony ovisac, which is conspicuous on the leaf of the plant, 
and the brown body of the female can be seen at one end of it. 
The eggs in this ovisac are numerous, perhaps some hundreds. 
Larva and second stage of female flat, oval, yellowish-brown. 
Male pupa covered with a waxy, clongated test as in the 
genus Cfenochiton, but there is no fringe and the segments of 
the test are not conspicuous; the test is oval and convex. 
Adult male yellowish-grey, the head rounded, with an 
anterior protuberance. ‘Two dorsal and two ventral eyes, and 
two ocelli. Antennz of ten joints, all hairy, Feet exhibiting 
only two digitules, the upper pair. Abdominal spike short, with 
two longish setze on each side, each pair of which are covered 
with cotton which is produced into a long white conspicuous cauda. 
Habitat—On camellia. In the South, chiefly m green- 
houses. In the Hutt Valley, Wellington, camellias in the open 
air are much subject to it. 
The female of this species is not unlike Lecanium hesperidun, 
but the formation of the white ovisac is a clearly distinguishing 
character, In late summer the female often drops off to the 
ground, leaving only the ovisac observable on the leaf.
