1222 REVISION OF THE GENUS HETERONYX, 



and hind coxse is a Utile feebler than in H. Bovilli ; the whole 

 undersurface is minutely coriaceous and therefore less nitid, the 

 ventral segments are almost without a trace of distinct punctura- 

 tion, the ventral series are stout and conspicuous, the antero- 

 internal tooth of the hind femora is very feeble, the uppermost 

 tooth on the front tibiae is much less than half the size of the 

 2nd, and the hind claws are bifid less minutely, the produced 

 apex of the basal piece being distinctly smaller than the apical 

 piece. 



This species can be distinguished from all the others (having 

 8-jointed antennae) of the 1st section by its impunctulate ventral 

 segments. If its stout ventral series should place it in the group 

 A (Proc. L.S.N.S.VV. 1888, p. 1328) it would fall under FF (same 

 page) with, frontalis ; among the species of BB (p. 1329) it would 

 have to follow badiics, — thus, 



" DDD. Clypeus not at all emarginate in 



front advena, Blackb." 



Locality uncertain ; but I believe it to be Central Australia. 



H. LILLIPUTANUS, sp.nOV. 



Minus elongatus; postice leviter dilatatus; rufo-piceus, antennis 

 testaceis ; pilis sat elongatis minus dense vestitus ; crasse sub- 

 rugulose punctulatus ; labro clypeum haud superanti ; antennis 

 8-articulatis; coxis posticis metasterno parum brevioribus ; ungui- 

 culis appendiculatis. [Long. 2 (vix), lat. 1 line. 



The clypeus is evenly reflexed all round and its free outline 

 forms a continuous even curve (the labrum being entirely below 

 it) ; its plane is not evenly continuous with that of the rest of the 

 head. The prothorax is half again as wide as long and its base 

 (which is bisinuate and rather strongly lobed hindward in the 

 middle) is more than half again as wide as the front which 

 is moderately emarginate with moderately produced and sharp 

 angles; the sides are rather strongly rounded, the hind angles quite
