This mealy bug was found upon Hahea gihhosa, growing in National Park, near Sydney, in 1893, when I then considered it a rare species, but I have since found it not uncommon on this shrub in the same Fig. 21.—Palaencoccux australis. The adult female is subglobular, convex on the upper surface, and measures about one-fifth of an inch; colour rich brown to black, with a row of yellow spots on the margin, with another row of spots midway, so that they appear to be two spots on each segment. The white cottony secretion forms a thin pad beneath the coccid, a regular fringe round the dark coloured body, and some scattered particles over it, but no true ovisac. The larvse are of the cottony cushion scale type, red and flattish, with six-jointed antennse, and the insects are attached to the main Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Froggatt, Walter
