regularly disposed and in a somewhat different order. The 

 tubercles in both species are nearly, if not quite, covered with 

 scales. 



20. — SCLERORINUS ACDMINATDS. 



Oblongo-ellipticus niger parce squamosus, thorace longitudi- 

 naliter rugoso lateribus tuberculato antice transversim im- 

 presso medio lateribus transversim impresso, elytris sub- 

 seriatim punctatis grauulatis interstitiis subobliterate re- 

 mote tuberculatis tuberculis antice elongatis postice sub- 

 elevatis versus apicem angustatis apice dehiscentibus obtuse 

 mucronatis. 



Long. 7^ lin., lat. 3 lin. 



Hab. South Australia. 



This species is black, and the sculpture throughout has an 

 obliterated appearance. The deep transverse impression on the 

 sides of the thorax constitutes, with the pointed shape of the 

 elytra, its most distinctive feature. 



21. — SCLERORINUS OBLITERATUS. 



Oblongo-ellipticus niger fusco-squamosus, thorace obliterate 

 rugoso-tuberculato, elytris subobliterate punctatis grauu- 

 latis subremote tuberculatis apice dehiscentibus obtuse 

 mucronatis recurvis. 



Long. 8 lin., lat. 3| lin. 



Hab. Victoria. 



The sculpture in this species is more obliterated than in the 

 last, whilst the thorax is without transverse impressions, and the 

 apex of the elytra is obtusely pointed, dehiscent and recurved. 



22. — SCLERORINUS MUCRONATDS. 



Oblongo-ellipticus niger parce fusco-squamosus, rostrc medio 

 carinato basi utrinque profunde impresso, thorace crebre 

 tuberculato lateribus ampliato, elytris seriatim rude punc- 

 tatis granulatis interstitiis 1, 2, et 3 remote tuberculc/^ia 

 tuberculis validis apice acute remote mucronatis.
