STRUCTURE

The female tests vary considerably, the typical ones like a leaf of dark reddish wax, the basal half dull with the upper portion a shining round bead of bright red wax. In the Queensland specimens the wax is more confluent, forming masses in rings around the twigs without any very regular structure (see Froggatt, W.W. 1921. A descriptive catalogue of the scale insects ('Coccidae') of Australia. Part III. Science Bulletin, Department of Agriculture, New South Wales 19: 1–43). Froggatt (1921: 28) illustrated the external appearance of the female test.
