Genus Fiorinia, Targioni. 
Uhleria, Comstock, loc. cit., p. 110. 
1. Fiorinia stricta, mihi. 
(Trans., vol. xvi., p. 124.) 
I find that this insect is more common than I had supposed. It occurs 
on several native plants, Astelia, Muhlenbeckia, Cordyline, ete. ; and on the 
last-named tree, in the Hutt Valley, I have seen it covering the leaves in 
countless thousands, as also on Phormium. I find also that in some speci- 
mens four very minute lobes may be detected between the sharp comb-like 
teeth of the abdomen. 
9. Fiorinia astelie, mihi. 
(Trans., vol. xiv., p. 217; vol. xi, p. 201.) 
Figs. 7-9. 
There are some modifications in the second female pellicle of this insect 
on different plants which do not seem to be sufficient for the establishment 
of new species, as I cannot detect in the adult stage or the general habit 
any clear differences. The normal pellicle exhibits, as described in Trans., 
vol. xi., p. 202, two prominent lobes just before the abdominal segment, 
and that segment itself terminates in a number of small blunt serrations. 
Sometimes, however, I have found specimens (on Cyathodes acerosa) where 
the two lateral lobes were absent, and others (on Astelia cumninghamii) 
where the abdomen ends, as. shown in the figure, in large, peculiar, tusk- 
like lobes. The normal form I have found most frequently on Atherosperma 
nove-zealandie. I am not prepared to consider the differences mentioned 
as amounting to more than variety.

Genus Ctenochiton, mihi. 
1. Ctenochiton viridis, mihi. 
(Trans., vol. xi., p. 211.) 
The male of this species, of which I have hatched out some half dozen 
specimens in the last year, presents no striking features. The test is 
white, glassy, oval, and slightly convex, about t inch long, divided into 
hexagonal segments marked with radiating lines like that of the female, 
and with a somewhat large fringe. Towards the posterior end it is cut 
across by a dividing line, and the insect when emerging lifts up the last 
segments of the test on this line as on a hinge. 
The perfect insect has antenne of nine joints, feet normal (but I eannot 
make out any digitules), thoracic band small and inconspieuous. There is 
a spine at the extremity of the tibia,
