The head has a small obscure depression between the eyes, and is 
finely and closely punctulate, with some scattered punctures of larger 
size. The prothorax is slightly wider than long (in some examples 
a little more so than in others) ; its .sides are scarcely constricted 
just behind the front and then a little rounded, so as to be at their 
widest (in some examples .scarcely so) a little in front of the base • 
its surface is punctured in the same fashion as the head and Ijears 
(as usual in the genus) a longitudinal fovea on the disc, and an 
angulate impression (not always strongly defined) near the front ; 
its sides are strongly rugose. The elrtra to nearly the middle are 
sculptured much as those of X. porcata, bearing longitudinal 
lines the interstices between which are divided into quadrate 
cavities by transverse lines, and the transverse being scarcely less 
elevated than the longitudinal lines the latter appear scarcely 
costate; but before the middle the transverse, and the alternate lon- 
gitudinal, lines begin to fail, the latter soon disappearing, — so that 
in the hinder j>art of the elytra the alternate interstices appear 
as strong costae bordered on each side vvith a row of fine punctures, 
and having the intervals between them quite flat. The shaj)e of the 
strongly compressed apical joint of the antennae (having its flat- 
tened face abruptly truncate at the apex with one of the front 
angles quite blunt and the other acute), .seems to l>e distinctive of 
the species. In the examples before me (perhaps all of the same 
sex) the two ventral segments preceding the apical two are closely 
punctulate in the middle and densely clothed with golden pubes- 
cence, the rest of the ventral surface being sparsely and faintly 
punctulate and thinly clothed with hairs. There appears to be 
some thin pubescence on the upper surface, but all the specimens 
before me are evidently aVjraded. 
Diflers from the pre\iously descril>ed species as follows, inter 
alia , — from Titana, Thoms., in much smaller size, from Mastersi, 
Mach, in the prothorax not being “ much longer than wide,” —
