REVISION OP THE GENUS HETERONYX, 
The insect is probably more widely distributed than most of its 
congeners ; I have specimens before me from S. Australia and 
N. S. Wales. 
H. HORRIDUS, sp.nov. 
Latior, postice vix dilatatus; minus nitidus; piceo-nigei', obscure 
pubescens ; supra crebre subtilius sat aequaliter (pygidio crassius 
sparsira excepto) punctulatus ; elytris apice setis crassissimis dense 
instructis ; abdominis segmentis 2-5 ad latera capillis erectis 
(lineatim transversira positis) instructis. [Long. 5, lat. 2§ lines 
This insect is very close to H. inceus^ from which it scarcely 
differs except in the following respects : — the clypeus is a little 
longer and consequently more strongly rounded in front with the 
middle of its anterior mai’gin very slightly sinuate in an upward 
direction ; there is a little more indication of transverse wrinkling 
on the elytra, and the bristles in their lateral fringe are much • 
coarser and instead of ceasing where the lateral margin turns 
inward towards the apex they become closer and coarser, forming 
a dense fringe two or three deep pointed backwards along the apex ; 
on the underside the puncturation of the ventral segments is 
evidently fainter, more sparse in the middle. The example 
before me is less decidedly pubescent, but may possibly be 
abraded. 
Also resembles H. tristis, differing in its smaller size, in the 
natui’e of the ventral series, in the anteriorly much more strongly 
rounded clypeus, &c., ttc. 
H. SOLIDUS, sp.nov. 
Minus elongatus ; postice leviter dilatatus ; nitidus ; rufo- 
ferrugineus, antennis palpisque testaceis ; clypeo prof unde sat 
crebre, vertice spai’sius, prothorace duplo (subtiliter et crassissime) 
sparsim, elytris crasse squamose, pygidio sparsim minus fortiter, 
punctulatis. [Long. 5, lat. 24 lines (vix (. 
The clypeus is evenly margined and scarcely emarginate in 
front ; the clypeal suture is strongly impressed and somewhat 
bisinuate, the plane of the suture not continuous with that of the
