REVISION OF THE GENUS HETERONYX, 
angles ; its sides diverge in a gentle curve to about the middle, 
and thence are nearly straight to the base ; the basal angles are 
roundly obtuse, the base rather decidedly and narrowly lobed 
in the middle, but scarcely sinuate on either side of the lobe ; the 
surface is sparingly sprinkled with very large coarse punctures, 
and bears a fringe of long erect hairs in front. The punctui'ation 
of the elytra is almost as coarse and sparse as that of the pro- 
thorax, but has a squamose appearance, and is much run together 
transversely by vague coarse wrinkles ; there is no indication 
whatever of sti’ise (in the example before me). The pygidium 
has faint traces of a keel in front, and has an obscure longitu- 
dinal fovea in front of the apex. The puncturation of the meta- 
sternum, hind COX 00 , and hind body is almost as in H. towns, 
except that the last-named part is nearly Ifevigate in the middle. 
The hind coxse are considerably shorter than the metasternum, 
and scarcely overlap the basal ventral segment. The hind femora 
are considerably wider than the intermediate, with their inner 
apical angle strongly produced in a tooth, and their external edge 
clothed with long soft hairs nearly to its apex ; the hind tibite 
have fine bristles or hairs on their inner side, sevei’al being 
crowded together close to the base. Claws bifid.

The clypeus is unusually elongate, the distance from its front to 
the clypeal suture (which is well-impressed and angulate) being 
scarcely less than from the latter to the back of the head ; it is 
sub-truncate in front, with a strong reflexed margin which becomes 
wider in the middle in such fashion that its dilatation appears as a
