286 THE GENERA AND SPECIES OF AMYCTERID^, 



24. ACANTHOLOPHUS TRUNCATICORNIS. 



Oblongus niger cinereo-squamosus, fronte excavata crista 

 truncata, thorace bifariam tuberculato lateribus dentato, 

 elytris rude punctatis subseriatim granulatis trifariam 

 tuberculatis. 



Long. 6| lin., lat. 2| lin. 



Hab. Newcastle. 



This species is like the last. It differs from it in the head by- 

 having the crest higher and still less lobed, in the thorax by 

 having the medial line and the spaces between the rows of medial 

 and lateral tubercles covered with silvery scales, and in the elytra 

 by its less regular sculpture, stronger tubercles, and silvery 

 marking. 



25. ACANTHOLOPHUS AnGASII. 



Oblongus niger cinereo-squamosus, fronte excavata, crista 

 subangusta elevata obtusa, thorace bifariam tuberculato 

 lateribus dentato, elytris seriatim granulatis trifariam tuber- 

 culatis apice conjunctim emarginatis. 



Long. 7 lin., lat. 2| lin. 



Hab. South Australia. 



This insect was sent to me from Adelaide some years ago by 

 G. F. Angas, Esq., after whom I have named it. It is closely 

 covered with brownish yellow scales varied with white on the 

 larger spines of the elytra. The forehead is excavated. The 

 crest is elevated and almost round at the tip. The thorax has 

 the two rows of dorsal tubercles and the lateral teeth as in A. 

 approxi^natus. The elytra are covered with granules disposed 

 pretty regularly on the back, and less regularly towards the 

 sides, and have on each three rows of small tubercles, the largest 

 towards the apex, the last tubercles of the row nearest the suture 

 being the largest and most approximate. The elytra are also 

 conjointly emarginate at the apex, but not mucronate. Perhaps 

 this species, from the character of the crest, would be more cor- 

 rectly placed in the other section.
