64 INSECTS NOXIOUS TO AGRICULTURE. 
or (as called herein) test, of glassy, waxy, or horny secretion. 
Test apparently homogeneous, really in most cases formed of 
aggregated segments over the insect, and prolonged beyond the 
body in a flat single fringe of separate, more or less triangular 
or quadrate, segments. Fringe not always present or conspicuous 
in all stages. Males, after first metamorphosis, constructing a 
test of similar character but varying form. 
This subdivision, when first established by Targioni-Tozzetti, 
included only the four genera Pollinia, Asterolecanium, Plan- 
chonia, and Lecanodiaspis, all of which are apodous in the adult 
stage of the female. In this work the two first of these are 
included in a new group, Hemr-Coccipinx ; Planchonia belongs 
to the group Coccip1inm; Lecanodiaspis is left in the present 
subdivision. For the reasons leading to these changes, and the 
inclusion in this subdivision of insects retaining the feet in all 
stages, see N.Z. Transactions, Vol. XI., 1878, p. 207, and 
Vol. XVI., 1883, pp. 125-128.

(Plate VIL., Fig. 1.) 
Test of adult female brown, hard, horny-looking, convex, 
slightly elongated, open beneath, loosely attached to twigs by 
the edges; at the top is the pellicle of the second stage, which is 
flat, and gives the test the appearance of an overturned basket, 
of which the pellicle is the foot. Length of test about =4:in. 
Remains of the thin white test of the second stage may some- 
times be seen on the pellicle. 
Test of the male small, white, glassy, elongated, convex. 
The young insect, extremely minute, naked and active, is 
flat, oval, brown, or rather reddish, usually found at the tips of 
young shoots or on leaves. . The antennze have six joints; on 
the last joint are several hairs, amongst which is one excessively
