866 AUSTRALIAN CuLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES,. 



it is much turned-up, and its sculpture does not differ much from 

 that of the same part of the prothorax ; the true margin of the 

 elytra is much wider than that of the prothorax, and is most erect 

 at about a third of its length from the base. 



A single specimen ; the locality of its capture is uuceitain.

Oblongo-ovalis ; convexus ; nitidus ; ater ; prothorace sub- 

 tilissime punctulato minute granulato; elytris sat fortiter

The prothorax is at its widest at the base, whence its sides are 

 contracted in a very gentle curve to the fronJb ; the anterior 

 projections are quite slender and slightly crossed ; the distance 

 from the base to the front margin is decidedly less than half 

 again as great as that from the front margin to the apex of the 

 anterior projections ; the intermediate expansions are moderately 

 wide, and are granulated not very tinely, with some appearance of 

 transverse wrinkling ; the margins are extremely thick and erect ; 

 the disc is very finely and evenly punctured and also tinely 

 granulated, but there is a space almost free fiom granules on 

 either side of the central line which is rather strongly keeled, the 

 keel being strongest at the base ; the width of the prothorax is 

 scarcely half again as great as its length. The elytra are densely 

 punctured in 13 rows, which, however, are rendered scarcely 

 traceable by the extent to which they are interrupted by the 

 rows of large round tubercles that occupy the alternate interstices ; 

 the 1st of these rows commences outside the scutellum as a strong 

 interrupted costa which runs obliquely to the suture, and then 

 margins it as a series of large tubercles nearly to the apex ; the 

 3rd row of tubercles also commences as an interrupted costa ; the 

 tubercles of the 3rd and 5th rows are rather larger than the 

 others and attain the apex; in the 5th row theie are about 10 

 tubercles ; the intermediate expansion is moderately wide at the 

 base, but soon becomes narrower, and continues so to the apex,
