The adult male has nine-jointed antenns, all the joints except the first 
long and hairy. Foot not so slender or long as in the last species, the 
tarsus being a good deal thicker. Digitules fine hairs. The penis, in some 
of my specimens, which as usual protrudes from the abdominal spike as a 
long white soft tube with minute hairs, seems to end in a somewhat large 
round knob, which I have not noticed in any other species. 
b. Ctenochiton elaocarpi, sp. nov. 
Figs. 12-14. 
Test of adult female oval, nearly circular, black in colour, divided 
into hexagonal and pentagonal segments which are not conspicuous, and of 
which the median series forms a very slightly elevated ridge somewhat 
lighter in eolour. The test is only slightly convex. The fringe is very long 
and conspicuous, the segments toothlike. Diameter of test, exclusive of 
the fringe, reaches } inch. 
The adult female fills the test, as usual. Colour black: antenn® 
somewhat long (fig. 14), of seven joints (I think, otherwise the third joint is 
abnormally long), a few hairs on the last joint. Foot normal; upper 
digitules strong and thick, lower pair very broad. On the skin are a 
number of large oval spots which appear to be the orifices of spinneret 
tubes. 
In the second stage this insect has a somewhat remarkable test of white 
wax, which is not, as usual, almost homogeneous, but is made up (fig. 18) 
of a number of detached plates somewhat resembling those of the genus 
Orthezia. The fringe is here even longer than in the adult, and its long 
white teeth curl in different ways, so that the whole test presents a rather 
elegant appearance. The insect beneath has the normal Lecanid shape, but 
wants the usual wavy outline of Ctenochiton. All round the edge is a row 
of sharp conical spines set pretty closely together. Feet normal; antenns 
of six somewhat confused joints. Extreme length of test, including fringe, 
sometimes 4 inch. 
I do not know the male. 
From Eleocarpus dentatus (hinau) in the neighbourhood of Wellington. 
This species is, in some respects, similar to C. fuscus, mihi (Trans., 
vol. xvi, p. 181), but differs in the much more flattened adult test, the 
longer antenne, the presence of the oval spots, and also in the peculiar test 
of the second stage. 
Ctenochiton flavus, mihi. 
(Trans., vol. xvi., p. 130.) 
The tests of the second stage of this species, which resemble somewhat 
Ceroplastes rusci, Linn., occur not uncommonly on Elaeocarpus and Lepto- 
spermum, near Wellington.
