chiw 5, large, copiously branched, tripinnate, set round the anus in a circle 
interrupted behind, retractile within a common cavity; this cavity has its 
opening irregularly 5-lobed, the lobes more or less tubercled. The pinnules 
of the branchie are lineated and tipped with black, the remainder being 
a waxy white. Foot rounded in front and behind, margin thin and undu- 
lated. There is a narrow notch in front, giving passage to the tubular 
proboscis; and immediately above it, in the groove between the foot and the 
mantle, are two minute flap-like projections. No odontophore, or buccal 
armature of any description.

1. Mytilaspis pyriformis, mihi. 
(Trans., vol. xi., p. 194). 
I nave lately succeeded in hatching out a male of this species. The insect 
(fig. 1) is orange-coloured, about jt, inch long, of the normal form, generally, 
of the Diaspide; the abdominal spike is of considerable length. Antenne 
(fig. 2) 10-jointed; foot (fig. 8) with four long fine digitules.. Haltere 
(fig. 4) normal 
As miastionl | in a former paper (Trans. vol. xii., p. 294), the males of 
the Diaspide are not easily distinguishable. There is little certainty to be 
obtained except by hatching from the puparia, and even then, as the puparia 
are often similar, it is easy to make mistakes. 
2. Mytilaspis leptospermt, sp. nov. 
Puparium irregularly pyriform, flat, light-brown, formed (besides the two 
Pellicles) chiefly of the bark-cells of the tree arranged longitudinally. The 
icle of the second stage is comparatively, small. 
Young insect normal. 
Adult female greyish-green, generally resembling M. pyriformis. Abdo- 
men ending in six lobes, of which the two median are conspicuous and 
Somewhat ae and floriated, the rest very small. Five distinct groups of 
€ upper group with about 15 openings, the others with from 
Spinnerets, th 
25 to 85. Single spinnerets none, or very few.
