MASKELL.—On some Coccidz in New Zealand, 195 
The adult female is deeply corrugated except (as in every Mytilaspis) on 
the cephalic portion. The corrugations bear a few strong spiny hairs. 
The abdominal pygidium shows an almost continuous arch of spinnerets 
over the anal orifice. In Mytilaspis buwi the groups are distinct. The 
spinnerets of Mytilaspis pyriformis run in a double ring round the anus, 
with here and there an outlying opening. Altogether there may be from 
60 to 70 openings in the arch. There are many single spinnerets scat- 
tered about, a large number of them more or less oblong; and they may 
be traced up the sides of the body as far as the corrugations extend. 
Plate V., figs. 3b and c, show the appearance of the female and the arrange- 
ment of the spinnerets. 
The abdomen, including all that is tinted yellow, does not show a con- 
tinuously curved outline. On each side, next to the last corrugation of the 
body, is a large triangular lobe, the apex furnished with scaly, triangular, 
serrated hairs. The rest of the abdomen shows a curve broken by small 
lobes, of which the two middle ones are the largest, the next two on each 
side smaller, and the rest inconspicuous. Between the lobes are scaly hairs, 
and near the edge runs a row of large oblong openings. 
I have a specimen of a scale from Dysoxylum spectabile, which seems to 
resemble much more nearly Mytilaspis buai; and this is not unlikely, as the 
specimen came from a greenhouse. 
3. Mytilaspis cordylinidis, sp. nov. 
Plate V., fig. 4. 
This scale, which appears to be also new, I have found on a great 
number of New Zealand plants, such as Cordyline, Asplenium, Phormium, 
Gahnia, Drimys, Astelia, and many others. I have also seen it on Eucalyptus 
globulus, but only in the vicinity of New Zealand trees. It is perhaps more 
abundant on the cabbage tree than on others; hence I have named it as 
above. 
The puparium is very long and narrow, generally straight, sometimes 
curved, semi-cylindrical. Length about 1 inch; breadth jj inch. Colour 
pure white, except at the end where the discarded tests are; these are 
bright yellow. The tests are oval; the second more elongated than the 
first, and the two together generally occupy rather more than a quarter of 
the length of the puparium. The eggs are small, oval, and of a bright 
yellow colour. 
The adult female is pale golden, about three times as long as broad ; the 
cephalic end a little flattened anteriorly, and above the rostrum are often 
seen the two minute hairy protuberances called rudimentary antenne. The 
body is somewhat corrugated, but less so than in M. re the gi : 
tions show a very few fine hairs, ^
