The antenns and feet do not, as long as the fringe is present, differ 
from those of C. perforatus. In the later stage, when the insect has 
attained its full size, they become very small proportionately, indeed 
almost atrophied, and difficult to make out. Maceration in potash shows 
them as existing, but they can be of no use to the insect. I cannot detect 
any difference between them and the antenns and feet of C. perforatus, 
except their comparative smallness. 
The edge of the female in the earlier stages presents the usual wavy 
outline which I referred to just now. 
In its last stage the female is enclosed in a thick coat of whitish-cottony 
felted fibre. The feet and antenn# are only to be made out after prolonged 
maceration in potash. The whole mass inside the felted matter is dirty- 
brown in colour, leathery in texture, preserving the acuminate pear-shape 
of the last stage. 
When arrived at this condition the insect appears on leaves of Panaz, 
Rubus, Coprosma, ete., like splashes of birds’ dung, giving the leaf a 
peculiarly nasty look. 
I have not found the male insect. 
8, Ctenochiton elongatus, sp. nov. 
Plate VII., fig. 14. 
I obtained this species in Auckland, on Geniostoma ligustrifolium. I have 
only the female, in one stage. The body is very much more elongated than 
in the last species, the width being not more than a quarter of the length; 
the edge of the body is, as usual, wavy; the stigmatie spines very pro- 
minent. 
The antenne and feet resemble those of C. perforatus, but I can detect 
no lower digitules. 
The fringe, which disappears in Canada balsam, differs from that of 
C. perforatus in the absence of the perforations and in the shape of the 
segments. Instead of the perforations there seem to be transverse wrinkles, 
and the segments are not roundly triangular but quadrate outwardly, their 
inner apices pointed; see plate VIL, fig. 144. The remainder of the test is 
divided into quadrangular scales. The whole test is extremely delicate and 
transparent. 
9. Ctenochiton spinosus, Sp. nov. 
Plate VII., fig. 15. 
I have this species from Atherosperma nove-zealandie. The female is 
brown, oval, about „y inch long, the edge slightly wavy. The antenne are 
thick, with seven joints, all nearly equal in length; the third joint is some- 
| what the longest; the seventh has a few hairs; plate VIL., fig. 15a, The
