 striis puncturis sat magnis leviter impressis, interstitiis 

 tuberculis seriatim instructis, his vix elevatis nisi in inter- 

 stitio 3° in quo tuberculus anticus cristam longitudinalem 

 bene elevatam format (fere ut Dotici pestilentis Olliff sed 

 minus elevatam) ; femoribus ad apicem haud ut dens pro- 

 ductis ; tarsis sat fortiter (fere ut A. fasciculati, De Geer) 

 elongatis.

 Readily distinguishable among the Australian Arceoceri by the 

 crest-like tubercle near the base of the third interstice of its 

 elytra. In a fresh specimen the alternate elytral interstices bear 

 a number of rather conspicuous little tubercles covered with 

 pubescence (on some of the tubercles darker, on others lighter, 

 than that of the general surface) which is a little longer than 

 of the general surface, while the basal margin of the elytra is 

 entirely and narrowly bordered with red-brown pubescence. In 

 abraded specimens the interstitial tubercles are much less con- 

 spicuous. Compared with Doticus palmaris, Pasc, and pestilens,. 

 Olliff, the present species is, inter alia, very much smaller and 

 narrower.

Readily distinguishable from its Australian congeners known 

 to me by its almost black colour, and its dark legs. It is a much- 

 broader and more robust species than A. bicristatus. In a fresh 

 specimen the whitish pubescent spots stand out very conspicuously 

 on the blackish general surface. They form a slight mottling on 

 the head, and front and base of the pronotum, an elongate patch 

 including the scutellum, a patch (of somewhat reddish tone) on 

 each shoulder, and a number of sma] spots on the alternate inter-
