Further collections from Mr. G. F. Hill, gathered in the neighbourhood of Port Darwin, have produced several interesting new species which are described below.

Aspidiotus destructor, Sign.

On foliage of Pandanus odoratissimus, Darwin, N. T. (Hill, no. 636). These puparia have a rather more brownish tint than is usual in the species.

Aspidiotus fodiens, Mask.

On Melaleuca leucadendron, Koolpinyah, N.T. (Hill, 17, 18), and on Pithecolobium moniliferum, Stapleton, N.T. (Hill, 637). In the older examples from Melaleuca the pygidial lobes are worn and are not of such a regular outline as in the fresher material from Pithecolobium, but the two forms agree in all essential characters.

Aspidiotus orientalis, Newst.

On Ficus orbicularis (Hill, 23), and on “ Milkwood Tree ” (Hill, 24), Darwin, N.T. Also “ on undetermined introduced tree ” (Hill, 639).

Aspidiotus unilobis, Mask.

On Melaleuca leucadendron, Koolpinyah, N.T. (Hill, 18, 19). And on the same plant at Stapleton, N.T. (Hill, 638).

Aspidiotus (Aonidiella) miniatae, sp. nov.

Puparium of female small, circular, moderately convex ; dull ochreous white ; pellicles proportionately large, reddish or reddish-brown. Diameter 0·75 to 1 mm.
