STRUCTURE

The waxy secretion of the adult female forming the test is dark red to black in colour, broad at the base and coming up to blunt point at the apex, like a large rose thorn; viewed from above it is seen to be fluted, with four distinct ridges. The outer surface is smooth, with fine white filaments curling through the openings in the test. Height of test, a quarter of an inch. Diameter base, one-fifth of an inch (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.
