MASKELL.—On New Zealand Coccides. 28 
lobe followed by a spine. Five groups of spinnerets: lower pair with 
12-14 orifices; upper pair with 7-10; uppermost group, 4-0. A few 
spiny hairs are on the edge of the abdomen. 
I have not been able to hatch out an adult male, though the male 
puparia are very numerous. 
Very abundant on Dysoxylon spectabile, often in company with Mytilaspis 
pyriformis. It seems to differ from all described species in the abdominal 
lobes of the female. 
2. Chionaspis citri, Comstock. 
(Second Report of Entomol., Cornell University, U.S.A., 1883.) 
An insect which occurs here sparingly on oranges imported from Sydney 
belongs, I think, certainly to this species. 
8. Chionaspis minor, 8p. nov. 
Female puparium white, small, not more than 444 inch in length, usually 
less; it is narrower and less pyriform than is usual in the genus, and is 
often bent in the middle ; pellicles yellow. 
Male puparium white, narrow, elongated, carinated, about gj; inch in 
length. 
Adult female not deeply corrugated, with general form of Mytilaspis ; 
colour dark brown. Abdomen ending in six small lobes, of which the two 
median, the largest, are closely contiguous. Between them and the next 
pair is a spine; then beyond the second pair another spine, a space, and 
a third pair of very small lobes; after a long space there is another spine. 
Five groups of spinnerets—uppermost group with 12-14 orifices; upper 
pair, 14-17 ; lower pair, 18-24; many single spinnerets. 
I have not seen the adult male. 
Abundant sometimes on Parsonsia; also frequently on Rhipogonum 
(supplejack). 
The smallness of this species and the contiguous median lobes of the 
female abdomen sufficiently distinguish it. 
Genus Diaspis, Costa. 
1. Diaspis boisduvalii, Signoret. 
In my paper of 1878 I reported this insect as occurring in hothouses. 
I find that, like Asp. camellia, it has spread out of doors, and is common on 
several garden shrubs. I have found it abundant on the wattle. 
2. Diaspis santali, mihi. 
(Trans., vol. xvi., p. 122.) 
I have received from G. E. Alderton, Esq., of Whangarei, specimens 
clearly belonging to this species, which in that locality seems to have spread 
from the native trees to the orchards, and is infesting in great numbers 
pear, plum and other fruit trees.
