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, 21uhlenbeckia, Cordyline, etc. ; 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. 



2. Fiorinia astelia, 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 cunninghamii) 

 where the abdomen ends, as shown in the figure, in large, peculiar, tusk- 

 like lobes. The normal form I have found most frequently on AtJterosperma 

 novce-zealandia:. I am not prepared to consider the differences mentioned 

 as amounting to more than variety. 



Group.— LECANIDiE. 

 Subsection I. — Lecanio-diaspime. 

 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 £ 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 antennas of nine joints, feet normal (but I cannot 

 ■ make out any digitules), thoracic band small and inconspicuous, There is 

 a spine at the extremity of the tibia,
