REVISION OF THE GENUS HETERONYX, 
angle whose extreme apex is scarcely rounded off and which is a 
little directed backward ; the base is bisinuate with the middle 
lobe very wide but rather strongly produced backward ; the surface 
is rather sparingly and strongly punctured, but the punctures are 
not large. The punctures on the elytra are much larger and closer 
than those of the prothorax and are not much run together by 
transverse wrinkles ; there is a rather distinct sutural stria, and 
several more are faintly indicated. The underside and legs scarcely 
differ from those of II. fulvo-hirtus, except in the puncturation of 
the middle part of the hind body being less sparse. The upper 
surface is almost devoid of pubescence in the example before me, 
but probably in a perfectly fi’esh specimen each puncture bears a 
very short adpressed seta. Claws bifid. 
A single specimen in the S. Australian Museum ; exact habitat 
not known. 
H. SPRETUS, sp.nov. 
Sat elongatus ; postice vix dilatatus ; sat nitidus ; ferrugineus ; 
capite antice crebre rugulose postice sat sparsim, prothorace 
sparsius minus fortiter, elytris crasse nec profunde nec crebre, 
}jygidio subtilius sat crebre, punctulatis ; elytris postice membrana 
angusta marginatis ; abdoinine ut H. fulvo-hirti hirsute. 
[Long. 4, lat. 2 lines- 
Very like H. Tepperi, differing in colour and size, and in the 
following particular’s ; — the clypeus is much less strongly rounded 
in fiont being almost subtruncate ; the keel forming the clypeal 
suture is strongly angulated in the middle ; the clypeus is on a 
plane slightly below the surface of the rest of the head, which is 
less closely punctured ; the puncturation of the prothorax is a 
little less strong, and its hind angles are rounded off (as in H. 
fulvo-hirtus) ; the pygidium is like that of H. fulvo-hir tits (hnt 
somewhat narrower), and the ventral segments are almost 
impunctate in the middle. Claws appendicidate.
