Another male labelled Albany (practically tiie same locality), differs some- 

 what in the crests, in the antennae having the tii'st joint of the funicle rather 

 longer and not much shorter than the second, and in the larger granules and 

 more numerous tubercles on the elytra; the latter number 9 — 10, fi — 8 and 3 — 4 in 

 the three rows. 



The species is allied to both A. hi/poleucus Boh. and .1. nirenvittatus Blackb. 

 From the former it may be distingiiished by its larger size and stouter supra- 

 orbital crests, from the latter by the biramate, not triramate crests, less convex 

 elytra and nmch smaller suliapical spines. 



In the Macleay Museum there are two males on the name label of this 

 species. Tlie elytral tubercles number 7 — 9, 5 and 3.

Head concave in front; intercristal ridge not very distinct; supraorbital 

 of a metallic coppery colour; median line of prothorax with a somewhat indefinite 

 whitish vitta; elytra with a longitudinal white spot at base and another anterior 

 to middle on suture, sides of prothorax and lower border of elytra dttate witli 

 white, the latter vitta not reaching base of elytra- 

 Head concave in front; intercristal ridge not very distinct; supraorbital 

 crests biramate, the anterior branch short, rather stout, truncate at apex, pro- 

 jecting forwards, posterior branch nearly twice as long as anterior, and more 

 slender, running upwards with a slight backward curve. Rostrum rather deeply 

 and widely concave, the lateral margins raised, rectangulate anteriorly, witliout 

 a definite tubercle; internal ridges little raised, very oblique, convergent to base; 

 basal foveae distinct. Antenna* long, rather slender, first joint of fnnide shorter 

 than second, club with a moderately long peduncle. Prothorax with median lobe 

 well produced; submedian tubercles irregulai-ly set, the apical tuljercle larger 

 than the rest, subcristafonu, second small, conical, third larger, erect, subconical, 

 fourth and fifth small, granuliform, transvei-sely placed, sixth larger, obtuse, 

 projecting somewhat backwards, basal tubercle smaller, erect; lateral margins 

 with a strong median spine, projecting outwards and curving strongly back- 

 wards, conjoined anteriorly with a smaller tubercle, posterior tubercle alisent, 

 the lateral margins indistinctly ridged and convergent towards base. Elytra 

 with rows of distinct granules, those on first interstice large at base becoming 

 smaller posteriorly and practically lost on the declivity; first row of tubercles 8 

 in number, small, obtuse but distinct, the basal one rather larger and the apical 

 two large and spiniform; second row with 5 — 6 conical tubercles, the apical 3 

 aliout twice as large as the basal ones and spiniform, also with one or two much 

 sr.ialler tubercles immediately behind humeral tubercle; humeral tubercle moder- 

 ately large and spiniform; third row with 4 acute tubercles, the first slightly the 

 largest. Ventral segments strigose, reticulate-imnctate. the sculpture olisolete on 

 first visible segment and less marked on second. Legs with strong subapical 

 notch on intermediate tibiae; posterior tarsi comparatively short and broad. 



?. As in male, but larger and more robust; prothorax with apical tubercle 

 of submedian row larger and spiniform, ihe apex curved backwards; elytra with 

 tubercles more numerous, first row with 10. the last 3 spiniform. second with 7 

 and 1 smaller one at base, third with 4, the last considerably smaller. Venter
