748 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



ly on the sides of the sterna, the scratches are deeper, on the 

 abdomen they are mostly transverse ; the elytral costae are fairly 

 distinct, but not sharply denned. One of the front claws is 

 much the same as those of the other legs, but the larger one is 

 thicker, more strongly curved, and with a wide basal appendix, 

 from some directions it appears to have a basal tooth (as in the 

 figure of politus), but it really has a wide flange-like appendix 

 there, which, viewed from the sides, gives the appearance as of a 

 tooth. 



Cryptodus quadridentatus, n.sp. 



Black, highly polished; parts of antennae obscurely diluted 

 with red. 



Head with crowded, coarse, reticulate sculpture; with a shal- 

 low median depression, on each side of which is a feeble eleva- 

 tion. Clypeus with margins rather lightly upturned, the front 

 feebly or not at all incurved to middle. Mentum deeply notch- 

 ed and tridentate at base; with crowded, reticulate sculpture, 

 becoming less confused in front. Antennae ten -jointed, basal 

 joint dilated at apex, more conspicuously on one side than an- 

 other. Prothorax with fairly large, and moderately dense, shal- 

 low punctures, each with a central pit, becoming more crowded 

 on the sides in front; median line lightly impressed. Elytra 

 with rows of rather large, elliptic, ringed punctures, becoming 

 small and more rounded towards sides, interstices with fairly 

 numerous and rather small but sharply defined punctures ; costae 

 well defined. Pygidium obliquely flattened, with dense, reticu- 

 late sculpture, but at apex with simple punctures. Front 

 tibiae with four teeth, the sub-basal one small, the others large. 

 Length, 22-23 mm. 



Hab. — Queensland : Dalby (Mrs. F. H. Hobler), Cunna- 

 mulla (H. Hardcastle). 



With the quadridentate front tibiae of C. foveatus, and with 

 very similar elytral sculpture, but the pygidium nonfoveate. 

 The reticulation of the head is continued even on to the clypeal 

 margins. The front tarsi of both specimens are simple. 



MELANDRYIDAE. 



Scraptia porosa, n . sp . 



Of a rather dingy flavo-testaeeous. Rather densely clothed 

 with short, pale pubescence.
