thin, and vanishes in balsam. The fringe, as shown in fig. 5, has rather 
wider and shallower segments than in C. perforatus, and I have not seen 
any of the peculiar markings, or pits, characterizing that species. The 
body is very thin in this stage. Length about #5 inch. 
Adult female (fig. 6) circular, convex above, flat beneath ; colour gener- 
ally greenish, but under the central divisions of the test deep purple, 
covered with a white, glassy or waxy, test of some consistence, which 
extends a little beyond the edge in an irregular fringe; but the fringe is 
often broken or absent, leaving the edge a continuous circle as in fig. 6. 
The test is regularly tessellated, the tessellations corresponding to those of 
the body: a row of pretty regular hexagons, the largest being in the centre, 
runs along the middle, having on each side another row of hexagons some- 
what wider, and beyond that a third row of hexagons: a fourth row, of 
which the outer angles are cut off by the edge, completes the circle. The 
middle row and the row on each side of it cover the purple patches of the 
body. Under each of the hexagons, between these and the outermost row, 
is a small swelling, or tubercle: if the insect be macerated in potash and 
rendered transparent, these tubercles are seen placed in a ring round the 
whole body about half way between the centre and the edge. I have failed 
to make out what is their function: under certain lights they have some 
slight resemblance to spiracles, but they are much too large, and moreover 
the Lecanide have but four spiracles, whereas there are twenty-four of 
these tubercles. 
The insect fills the whole test, and in its last stage is slightly hollow 
underneath : the young, as in Lecanium depressum, are to be found in the 
cavity thus formed. The antenne (fig. 7) of the adult have seven joints, 
the third joint being the longest. The second, third, fourth, and fifth joints 
have each one hair, the seventh several hairs. Feet (fig. 8) normal of the 
genus: the lower digitules rather broad. 
The average diameter of the adult insect is about =, inch. 
Not uncommon in the North Island on Piper excelsum: sometimes on 
other trees. I have not found it in the South. 
The almost regularly circular form and the colour, green with purple 
patches, of this species readily distinguish it from others of the genus. It 
forms a handsome opaque object for the microscope.

T have succeeded lately in procuring both the young insect and the adult
