MaskELr.—On some Coccidg in New Zealand. 197 
Males of this species are not so rare as in some others, and I hope before 
long to have a perfect specimen.* 
Subsection 2.—Aspiniotus, Bouché. 
This genus is characterised by a round, or nearly round, puparium ; the 
discarded pellieles are in the middle, and usually their major axes are inclined 
to eaeh other. Several species are known in Europe. 
1. Aspidiotus epidendri, Bouche. 
This is a well-known species. In Mr. Duncan’s hothouses it may be 
found in abundance upon the Seaforthia palm, upon Lelia anceps and other 
orchids, and on several other plants. 
The puparium is round, flat, of a dirty white colour, sometimes (as on 
the wattle) brownish ; the pellicles in the centre are yellow; the fibres 
run in interlacing circles. 
The eggs are yellow ; the young insect is oval, somewhat broader than 
in Mytilaspis pomorum, and has at the posterior extremity two protruding 
lobes with a pair of very minute lobes between them. 
As a rule, the insects are found in considerable numbers, in colonies, 
the puparia of the females intermingled with the young and with the 
cocoons of the males. 
The pellicle of the second stage is oval, tapering to the posterior 
extremity, 
The adult female is almost round, or rather in the shape of a peg-top. 
Plate V., figs. 6a and b, show the insect and its puparium. The curve of the 
cephalic portion is circular and smooth ; no hairs are visible, but the two 
rudimentary antennæ can be seen. The abdominal region is yellow, ending 
in lobes of which the two middle ones are the largest; between the lobes 
are very fine hairs. The pygidium has four groups of spinnerets ; the two 
upper groups have from eight to ten openings, the two lower from six to 
eight. Many single spinnerets. 
The puparium of the male is elongated, cylindrical. At one end is seen 
the pellicle of the first stage. The male escapes from this cocoon, when 
perfect, backwards. This mode of egress is, as I understand, not uncom- 
mon amongst the Coccide. 
In the pupa stage the male (plate V., fig. 6d) exhibits the wings, legs 
and abdominal spike coiled up to fit the cocoon. 
* Since writing this paper I have obtained a specimen of the adult male. The wings 
are about equal in length to the body. The antenns have ten joints, of which the two 
first are very short and thick, the rest very long and thin, covered with hairs and equal 
to each other with the exception of the last which is spindle-shaped. These antenne 
resemble those of the hie 3 of Depi giga dece pur The thoracic band is 
inconspicuous. The le g airy.
