1226 REVISION OF THE GENUS HETERONYX, 



H. PUBESCENS, Er. 



I have before me an example taken in Tasmania by Mr. T. G. 

 Sloane, which I cannot doubt is this species, as it agrees perfectly 

 with Erichson's description. M. Lacordaii-e (Gen. Col. III., p. 232, 

 note) states that H. puhescens has simple claws, on the strength 

 of which I expressed the opinion (Proc. L.S.N.S.W. 1888, 

 p. 1328), that it could not be a true Heteronyx; but with the 

 present specimen before me (which has distinctly appendiculate 

 claws, the basal piece about twice as large as the apical), I am 

 compelled to conclude that Lacordaire was mistaken. In Masters' 

 Catalogue the species is assigned to Caidohius. In my tabulation 

 H. puhescens would fall side by side with H. gracilipes, Blackb., 

 from which it differs m^er aZia by the very much more obtuse teeth 

 of its front tibiae, the uppermost of them being subobsolete. 



H. Randalli, sp.no v. 



Minus elongatus ; postice vix dilatatus ; ferrugineus ; pilis 

 depressis minus dense vestitus ; subtilius minus crebre (capite 

 crasse rugulose) punctulatus ; labro clypeum baud superanti ; 

 antennis 9-articulatis ; coxis posticis metasterno sat brevioribus ; 

 unguiculis appendiculatis. [Long. 3? (vix), lat. 1? lines. 



The clypeus is evenly reflexed all round and its free outline 

 forms a continuous curve scarcely flattened or subsinuate in front 

 (the labrum being entirely below) ; its plane and puncturation are 

 almost perfectly continuous with the rest of the head, from which 

 it is separated by a very obscure suture. The prothorax is about 

 I again as wide as long, its base (which is scarcely bisinuate but 

 considerably lobed hind ward all across) something less than | 

 again as wide as its front which is only moderately emarginate 

 with angles not very sharp nor strongly produced ; the sides are 

 moderately rounded-and the hind angles are quite rounded off. 

 The elytra have scarcely a trace of striation even along the suture, 

 their ti'ansverse wrinkling is feeble, their lateral fringe is normal.
