With the exception of the abdominal lobes and the numbers of spinnerets 
in the groups, the adult female resembles Aspidiotus atherosperme. 
9. Aspidiotus aurantii, sp. nov. (?) 
Plate VI., fig. 8. 
This is not an indigenous species, being found in immense numbers 
upon the oranges and lemons in our shops, imported from Sydney. As, 
however, it occurs on orange trees growing at Governor’s Bay, I introduce 
it here. 
M. Signoret describes, under the name of Parlatoria zizyphi, or aurantii, 
an insect infesting orange trees in Europe. Its form, as given in his plate 
V., fig. 9, bears certainly great general resemblance to the insect I am 
describing, but it differs altogether in the shape and colour of the puparium, 
and the abdominal lobes are also different. . 
The puparium of Aspidiotus aurantii is round, yellowish, flat. The 
insect, in the centre, is curiously shaped. It has a generally spherical out- 
line, but looks as if, from rich feeding, rolls of fat were produced, making 
the corrugations of the body very largely overlap the abdomen. It is 
yellow, the abdomen being the deepest coloured. The curve of the body 
and head is regular and smooth; the rudimentary antenna are absent; the 
abdominal region, very small in comparison with the rest, ends in six lobes 
of which the two middle ones are the largest. There are no groups of 
spinnerets, Pan 
The young insect (second stage) is somewhat different, being of a nearly 
regular oval shape, without the rolls of fat. 
The male is very small, brown in colour; the antenne have ten joints. 
The two first joints are very small, round and smooth; the third, fourth, 
fifth and sixth equal in length, the seventh, eighth and ninth half as long, 
the tenth somewhat shorter still and pointed. All the last eight joints show 
numerous hairs. The thorax is short and thick, the thoracic band oceupy- 
ing more than one-half the width; the abdomen short, the double spike of 
some length. The wings are oval, about as long as the body. The legs 
are hairy, femora thick, tibie longer, thicker at the end next the tarsus than 
at the other end; tarsi broad at the top, tapering gradually down to the 
usual single claw. The hairs on the femora are much fewer than those on 
the tibie and tarsi. 
This insect does not correspond in any particular with the species 
described by M. Signoret, except in the general outline of the adult female, 
resembling Parlatoria. Nevertheless, as it is manifestly not a species 
indigenous to New Zealand and must be known to entomologists, I give it 
the name of Aspidiotus aurantii only in default of better information than I 
have at present, M. Schrader, in the work above cited, mentions an insect
