Maskell. — On New Zealand Coceidre, 25 



The only means of distinguishing this from the male of C. perforates 

 seem to he in the test, where the rows of perforated air-cells characteristic 

 of that species are absent. 



2. Ctenochiton spinosus, mihi. 

 (Trans., vol. xi., p. 212 ; vol. xiv., p. 218.) 



I have to add to the habitat of this species the bark of Muhlenbeckia and 

 of Melicope ternata. The insect is very difficult to detect, as it is usually of 

 almost the same colour as the bark. 



3. Ctenochiton hymenantliera, sp. nov. 

 Figs. 10, 11. 



Test of female waxy, circular, convex, dirty white, yellow, or brownish, 

 formed of a number of hexagonal or octagonal segments, which are also 

 convex, giving it a rough appearance. Fringe not very conspicuous. 

 Diameter of test about J^-inch. 



Test of' male glassy, white, oval, segmented, slightly convex, segments 

 of fringe small. Length about Jg-inch. 



Adult female yellowish brown, fitting the test. Antennas (fig. 10) of six 

 joints, of which both the second and third seem sometimes double. Foot 

 normal ; upper digitules long fine hairs, lower pair broad. The spiracular 

 spines are strong and conspicuous. The skin is divided into segments 

 corresponding to those of the test, the divisions being marked by lines of 

 spinneret orifices which are small and simple. 



In the second stage the usual wavy edge of the genus is not generally 

 apparent. 



Adult male somewhat thick and short. Antennfe (fig. 11) of nine joints, 

 the first short and thick, the remainder long and nearly equal : each joint 

 after the first has many nodosities from which spring longish hairs. Foot 

 long and slender, especially the tibia. Digitules fine hairs. Thoracic band 

 inconspicuous. Abdominal spike short and blunt. 



This species is usually accompanied by a great quantity of very black 

 fungus covering and rendering unsightly the whole plant on which it lives. 



From Hymenanthera crassifolia. 



This insect seems to be intermediate between C. piperis and C. depresses, 

 differing from both in the rugose female test and the distribution of the 

 spinneret orifices. 



4. Ctenochiton piperis, mihi. 

 (Trans., vol. xiv., p. 218.) 



The male test of this species is more oval than that of the female, and 

 somewhat smaller, averaging about -£§ inch in length. It is otherwise so 

 similar in its divisions, colour, and general appearance, that it cannot be 

 mistaken for that of any other species,
