REVISION OF THE GENUS HETERONYX, 
sides. On the anterior tibia? the uppermost of the external teeth 
is small, but well defined and sharp. 
Very distinct by the red apex of the elytra, forming a defined 
round spot on either side. 
A single specimen occurred to me on Yorke’s Peninsula. 
H. Lindi, sp.nov. 
Sat brevis ; postice vix dilatatus ; minus nitidus ; setis longis 
erectis pallidis minus crebre vestitus ; niger, antennis pedibusque 
picescentibus : capite sparsim subtilius (clypeo nonnihil crassius 
crebrius), prothorace sparsim subtiliter, elytris vix perspicue, 
punctulatis ; pygidio sparsim granulate ; labro clypeum vix 
superante ; antennis 8-articulatis ; unguiculis bifidis.

. Closely allied to H. maculatus, and scarcely differing from it on 
the upper surface except as indicated in the Latin diagnosis, in 
the absence of the apical red spot, in the slightly less transversity 
of the prothorax, and in the presence of some faint scratchy 
striae (especially one near the suture) on the elytra, the surface of 
which, though not nitid, would be very smooth were it not for 
some obscure roughnesses which form the bases of the long hairs. 
The underside scarcely differs from that of H. submetallicus 
except in being a little more shining, with puncturation (though 
spai’ingly and lightly impressed) distinct ; whereas in submetallicus 
it is so faint as to be hai'dly indicated when viewed under a very 
strong lens. I have felt some little hesitation in regarding this 
species as distinct from submetallicus, hut have concluded that 
the above-named difference, together with the much smaller size 
of H. Lindi, its having no tendency to metallic colouring, its 
pilosity being nearly white (instead of ferruginous), and the hind 
angles of its prothorax appearing, when viewed from above, 
evidently more defined, can hardly be regarded as indicating a 
mere variety.
