26. — ACANTHOLOPnUS SCABROSUS. 



Oblongus niger fusco-squamosus, capite bicristato cristis acute 

 bidentatis, thorace dorso bifariam tuberculato lateribus 

 valide dentato, elytris seriatim granulatis trifariam tuber- 

 culatis tuberculis squamulis nigris obtectis, pedibus sub- 

 piceis. 

 Long. 8 lin., lat. 3j lin. 

 Hab. Blue Mountains and Mudgee. 

 This insect is covered, particularly on the tubercles of the 

 elytra, with black scales. The head is slightly excavated 

 between the crests, which are deeply bidentated and rather 

 pointed, the posterior tooth being the most acute and pointing 

 backwards. The tubercles on the disc of the thorax are small, 

 the first and last being elongate ; those on the sides are of the 

 usual character. The elytra are broader than the thoi-ax, and 

 have three series of rather strong tubercles on each, while between 

 the suture and the first row of tubercles there are three distinct 

 rows of granules in the female. The apex of the elytra is a little 

 dehiscent, and the legs have a slightly pitchy appearance. 



27. ACANTHOLOPHDS MUCROXATUS. 



Oblongus niger parce squamosus, capite bici'istato cristis 

 obtuse bidentatis, thorace dorso bifariam tuberculato lateri- 

 bus valide dentato, elytris seriatim granulatis et rude 

 punctatis trifariam valide acute tuberculatis tuberculis sub- 

 nitidis apice valide mucronatis. 

 Long. 9| lin., lat. 3| lin. 

 Hab. Blue Mountains. 

 This species is larger and less covered with scales than the 

 last, and indeed presents many distinctive characters, the chief 

 of which is the large obtuse horizontal mucronation at the apex 

 of each elytron.
