 but not mucronate.

Oblongus niger cinereo-squamosus, capite utrinque bicristato, 

 fronte excavata, thorace bifariam tuberculato lateribus 

 dentato, elytris seriatim granulatis serie secunda postice

 lineatis apice dehiscentibus bi-eviter mucronatis.

My only specimen, apparently a female, is of a dull black 

 with cinereous scales. The head is excavated in front. The 

 crest is large and dee])ly bilobed. The rostrum has the apex of 

 each lateral margin elevated into a tubercle. The thorax has a 

 row of five tubercles on each side of the medial lin:^, the apical 

 tubercle being bidentate, and two strong tubercles on its sides, 

 one near the middle with a smaller one on its aritei'ior face, the 

 otlier near the base. The elytra are maiked on the back with 

 rows of granules, the second row from the suture terminating in 

 a strong tubercle, and on the sides with whitish lines separated 

 by transverse rugose granulations. Besides these there are three 

 rows of strong tubercles on each elytron. The apex is dehiscent 

 and slightly mucronate. 



23. — A'iANTflOLOPHCS SQCALIDUS. 



Oblongus niger fusco S(|uamosus, fronte excavata crista fere 

 truncata, thorace bifariam tubercalato lateribus dentato, 

 elytris striatis interstitiis granulatis trifariam tuberculatis 

 lateribus rugosis apice mucronatis. 

 Long. 6^ lin., lat. 24 lin. 

 Hab. Merimbula, New South Wales. 

 This species is very like A. approxitnatus, differing from it 

 chiefly in the crest, which is scarcely bidentate, and indeed is 

 almo.st truncate, and in not having the last tubercle in the row 

 nearest the suture of the elytra so much approximated as in the 

 Melbourne species.
