(Plate IX., Fig. 1.) 
Test of adult female absent or fragmentary; very thin, waxy, 
white, divided into pentagonal or hexagonal segments, each of 
which exhibits numerous concentric wavy curves, crossed by 
straight lines radiating from the centre ;* the segments are 
separated by double lines of minute spots, corresponding to the 
spinneret orifices of the insect. No air-cells. Fringe seldom 
visible. 
Test of female of second stage very thin, white, waxy, flat, 
divided into segments with concentric curves and radiating 
lines as in the adult. Fringe of broad segments. No air-cells. 
Length, about yin. 
Test of male glassy, white, elongated, slightly convex, divided 
into segments similarly marked to those of the female. Ab- 
dominal segments separated from the test by a transverse line, 
or hinge. Length, about din. 
Adult female bright-green in colour, thick, elongated or 
pyritorm, the cephalic portion somewhat acuminate; length 
sometimes reaching din. It produces a conspicuous depression 
in the leaf, in which the body is partially buried. Antenne of 
six joints (apparently seven, but the third jot shows the false 
division or depressed ring), often atrophied. Feet normal, coxz 
and femora thick. After gestation the insect frequently becomes 
brown, covered with a mass of white mealy or felted secretion. 
Female of the second stage thin, filmy, translucent ; flat, 
elongated, with wavy outline ; colour green ; length, about 5),im. 
Antenne of six joints. 
Adult male greenish-yellow ; length, about jin. Antenne 
of nine joints. Feet normal; digitules absent. A strong spine 
at the extremity of the tibia. 
Habitat—On Panax arboreum, Coprosma lucida, Hedycarya 
dentata, Atherosperma Nove-Zelandie, Rubus australis ; Canter- 
bury, Otago, Wellington, Nelson, Auckland, Hawke’s Bay. 
This is probably the largest known species of the Lecanidine. 
Its size and bright-green colour in the adult state clearly dis- 
* The radiating lines and concentric curves of these segments are usually 
somewhat conspicuous, at least on the adult female, and serve to distinguish the 
test fromr that of C. elongatus, which otherwise resembles it.
