MasxeLL.—On New Zealand Coccide. 188 
Test of the male elongated, narrow, flat beneath, slightly convex above, 
white, glassy, thin and brittle, with a conspicuous fringe of which the 
segments are truncato-triangular (fig. 82). The test is divided into tessel- 
lations, the median row of which is quadrangular, with two series of pen- 
tagonal divisions between it and the fringe. Near the abdominal extremity 
a transverse narrow slit cuts the test in two, leaving a small segment at the 
extreme end apparently separate. Length of the test about 7 inch. The 
adult male is yellowish-red in colour, about 3 inch in length, exclusive of 
the wings. General form normal. Antenne long, with ten joints, all 
long and equal, except the two first which as usual are very short: all the 
joints have several hairs. Legs normal, but the tibia are very long and 
slender and only a little thickened at the tip; tarsi somewhat thick ; digi- 
tules fine hairs. Abdominal spike longer, I think, than usual, and very 
slightly curved. Four pairs of eyes. 
On Plagianthus, Cyathea, and a few other plants sent to me from 
Hawke's Bay by the Rev. Mr. Colenso. 
This insect resembles, to the naked eye, somewhat nearly Ctenochiton 
perforatus, mihi, but the female differs in the absence of the curious perfor- 
ations in the test of that species and in the shorter and thicker antenna 
with also more long hairs on the last joint. The test of the male is also 
different. 
Subsection II.—LcANIEX. 
Genus Lecanium, Illiger. 
1. Lecanium sp., parasitized. 
It is by no means uncommon, especially in the North Island, to find on 
many trees in the forests a number of circular brown spots on the leaves, 
varying from 4 to 4l inch in diameter, slightly convex and with a velvety 
appearance. On examination these spots are found to be chiefly fungoid : 
they cannot always be easily detached from the leaf, and often several of 
them are connected together by a thin sheet of fungoid growth so that a 
large patch comes off at once. On turning them over, very often nothing 
more is to be seen than from the upper side: but many specimens may be 
found showing in the centre of the under-surface a small oval object 
embedded in the brown mass. Closer examination shows this to be, in 
most cases, a Lecanid insect; but identification is very difficult, and it is 
almost impossible to make out the organs, even after prolonged maceration 
and boiling. It is impossible to render the insect transparent enough for 
complete study. i 
This is the effect of parasitism, and the insect in question is a Lecanium 
which has become covered with fungoid growth. Ido not know exactly to 
what species to refer it. In general form it resembles L. hesperidum, but it
