which, however, it may be distinguished by its more oval shape and by its very beautiful colour.

DITROPIDUS VENUSTUS, n.sp.

Very briefly ovate. Head and prothorax coppery, elytra bronzy-purple, pygidium coppery bronze; under-surface black, antennæ and palpi obscure testaceous, four anterior legs obscure piceous-red.

Pro

Head densely punctate; median line widely and rather faintly impressed; eyes rather larger than usual. thorax with dense clearly-cut punctures, sides strigose; basal lobe indistinctly notched. Elytra seriate-punctate, punctures very distinct, sides tristriate; interstices smooth and impunctate. Length 23mm.

Hab.-Brisbane (Mr. A. J. Coates).

Possibly close to cupreus trabeatus or angustifrons, but in both specimens under examination the elytra are of a beautiful bronzy-purple, very different to the coppery tone of the prothorax.

DITROPIDUS LATERALIS, n.sp.

Briefly ovate; bluish; the head and the sides of prothorax and elytra with coppery reflections; under-surface black; mouth-parts, antennæ, tarsi, and extreme apex of tibiæ tes

taceous.

Head rather densely punctate; median line distinct. Prothorax with dense and distinct but not very clearly-cut punctures; basal lobe notched. Elytra faintly seriatepunctate, sides bistriate; interstices very faintly rugulose. Length 33mm.

Hab.-W.A.: Garden Island.

DITROPIDUS BRACHYSOMUs, n.sp.

Very briefly oblong-ovate; black, the upper-surface with a slight bronzy or coppery gloss; basal joints of antennæ obscure testaceous.

Head with rather small punctures; median line faintly impressed. Prothorax (except at sides) not very distinctly punctate, sides tristrate; interstices faintly but distinctly rugulose. Length 2mm.

Hab.-W.A.: Geraldton.

cœlestis. vigilans.

striato-punctatus.

...

Punctate striæ very distinct to suture melasomus.
Punctate striæ indistinct near suture sobrinus.
With a coppery or bronzy gloss, wholly or in part.

Not always entirely concolorous, but never red or diluted with red; the colours

usually metallic.

DITROPIDUS CONCOLOR, Saund.

This species is variable to a certain extent in size. Specimens may occasionally be taken which are of a bright blue colour. In Western Australia, where the species is very abundant, it is very destructive in spring to the young shoots and leaves of fruit trees; it occurs also on many wild plants. In New South Wales I have taken it on Acacia decurrens at Braidwood.

LIST OF THE DESCRIBED

COLEOPTERA

OF

TASMANIA.

By ARTHUR M. LEA.

THE Coleoptera of Tasmania have never been considered as a whole since the time of Erichson, (*) and no list or catalogue of the species has ever been compiled. About 10,000 species have now been recorded from Australia and Tasmania, of which scarcely 400 have been described from Tasmania. A very imperfect knowledge of what species are confined to the island exists, as species supposed only to occur there, are constantly being found in Victoria and New South Wales, and even sometimes in Western Australia and Queensland; on the other hand, Tasmanian collectors frequently obtain mainland species which have never been recorded from Tasmania.

I have considered it advisable, therefore, to prepare a list of the species hitherto recorded from Tasmania, adding to the list such species as I have seen in Tasmanian collections, or have myself taken in Tasmania. In this list, the genera and families are placed as far as possible in the order in which they appear in Masters' " Catalogue of the Described Coleoptera of Australia;" the species are placed alphabetically. All known synonyms have been omitted.

In the list an asterisk (*) has been placed after those species which are known to occur on the mainland, whilst another (†), has been placed after those species which have been introduced. Deducting the introduced species (40) there remain 1000 species and varieties, of which 423 are so far, known only from Tasmania; and one being known only from New Zealand and Tasmania; but probably many of these will be found to occur on the mainland, especially as the beetles of the Australian Alps (and Mount Kosciusko in particular) become better known.

When the Coleoptera of Tasmania have been thoroughly worked out, it will probably be found that there are over 2000 species, whilst in the whole of the Australian States, there are probably at least 20.000 species.
