_Dilochrosis atripennis_ is one of our largest typical cetonids; it measures over 1½ inches in length and is broad in proportion; it is shining black, with the sides of the thorax and elytra, except a stripe down the centre (broadest in front), rich reddish brown. It is not uncommon about Cairns, N. Queensland, and ranges down, according to Masters, to the extreme north of N.S. Wales. The Fiddler, _Eupoecila australasiae_, about ¾ of an inch in length, is black and reddish brown, marked upon the thorax and elytra with green stripes, forming a fanciful resemblance to a lyre upon the back, from which it takes its popular name. The larvae of this and the following species, (thick fleshy white grubs) feed in the rotting trunks of dead grass trees, forming stout oval cocoons in the larval stage; and the beetles are very abundant upon the Angophora flowers in the early summer.

(“Agricultural Gazette,” N.S.W.)] _Micropoecila cincta_ is another common species about Sydney; is slightly smaller; of a general black colour, the outer edges of the thorax and wing covers broadly margined with reddish yellow; and its life history and habits are identical with the “Fiddler.” _Polystigma punctata_ is one of our smaller common species; is of a dull yellow colour irregularly but finely spotted all over the upper surface with black dots. A second species, described under the name of _P. octopunctata_, is I think only a variety; my specimens all come from the Shoalhaven, N.S.W. _Cacochroa gymnopleura_, about the same size, is black, rather downy on the under surface; and is remarkable for having a variety as common as itself, with reddish brown thorax and elytra. The members of the Genus _Trichaulax_ are remarkable for having the elytra deeply furrowed, and these depressions filled with close short hairs. They are all large fine beetles over an inch in length; _Trichaulax philipsii_, taken about Sydney on the flowers of the blood-wood late in the summer, is marked with grey hairs. _T. marginipennis_ is common to N.S. Wales and Queensland; it has bright reddish hairs completely clothing the tips of the wing covers and abdomen. _Diaphonia dorsalis_ is a large common species, of a general black colour, with the upper surface of the thorax and elytra yellowish brown variably marked with black in the centre. It often comes flying about the garden with a loud hum, and even sometimes comes in through the open window.
