head but sparser. Elytra rather long and thin, vaguely- 

 striated ; with fairly large punctures. Pygidium with fairly- 

 dense punctures. Front tibiae tridentate, the two front teeth 

 large, the other small ; basal joint of hind tarsi slightly shorter 

 and thicker than second. Length, 6"5-8 mm.

The hind angles of the prothorax are not so flattened as 

 in nigrolineata, but as the head has some long hairs it possibly 

 would have been associated with that species by Blackburn ; 

 it is certainly allied to it, differing in being much smaller 

 and narrower, hind angles of prothorax sharper, etc. From 

 some directions most of the upper-surface appears to be black, 

 but from others much of the elytra of a dingy red, it is diffi- 

 cult, however, to see their true colours on account of the 

 brilliant opalescence (this obscures the margins of the punc- 

 tures, so that it is not easy to be sure of their exact size) ; 

 from some directions even this changes to a pruinose gloss. 

 One specimen, with much the same opalescence, has the elytra 

 of a rather dingy red, with obscure darker lines. 



Three specimens from Kurrajong (C. T. Musson) and 

 Mittagong (H. J. Carter and A. M. Lea) possibly belong 

 to this species, and are probably females ; they differ in being 

 much paler (almost uniformly castaneous), without opalescent 

 gloss, with denser and larger punctures, especially on the 

 elytra, where they are rather crowded and moderately large, 

 and shorter legs. 



Anodontonyx niger, n. sp. 



Black, shining; antennae, palpi, and legs dull red, pro- 

 sternum and front of clypeus sometimes obscurely diluted 

 with red. Prothorax and elytra with a thin fringe of red- 

 dish hairs, and a few hairs across apex of prothorax, rest of 

 upper-surface glabrous ; under-surf ace and legs sparsely 

 clothed. , 



Head with fairly dense punctures at sides, but somewhat 

 sparser in middle. Clypeus with margin rather strongly 

 upturned in front but less strongly on sides, each side of 

 base lightly produced, hind suture rather strongly drawn 

 backwards to middle; punctures near base more crowded 

 than between eyes, but becoming sparser in front. Antennae 

 eight-, club three-jointed, second joint subglobular, distinctly 

 wider than third; club small. Prothorax about twice as wide 

 as long, front angles produced and subacute, hind ones gently 

 rounded off; punctures rather small but sharply denned, 

 nowhere crowded. Elytra rather short; with geminate rows 

 or rather shallow punctures, the interstices with rather
