Mentum transverse, anterior angles strongly inflexed, 
middle portion large, prominent, transversely subcordiform , 
and sulcate down the middle from apex nearly to base : 
labium short, strongly ti'ansverse, broadly emarginate in 
front, angles rounded: palpi wanting: sides of submoitum 
produced into a very large, angidar, prominent tooth : 
ff?da with a deep, longitudinal furrow which becomes faint 
and bifurcate behind : head large, subquadrate, immersed 
in prothorax nearly to the eyes; front very long, plane, 
gradually declivous : antennary orbits long, narrow, pad- 
like (" en bourrelet"), subparallel, separated from the front 
by a deep, straight groove, extending from the eye to the 
anterior border : epistoma short, trapezoidal, front angle 
strongly bent down, apex slightly emarginate, the suture 
represented by a faint angulate line at each side, and a 
slight depression in front of the line, within the angle : 
eyes narrowly re'niform, projecting beyond the sides of the 
antennary orbits : labrum prominent, strongly transverse, 
angles rounded, slightly emarginate at the middle of the 
anterior border, membranous hinge Aasiblc : prothorax 
wider than long, arcuate-emarginatc in front, fi."ont angles 
very prominent, acute, directed forward, sides gradually 
widened to beyond the middle, suddenly constricted near 
the base, hind angles acute, directed outwards, not over- 
lapping the shoulders, lateral margins somewhat expanded, 
attenuate, the edges strongly thickened, gradually more 
feebly so from behind the middle to the hind angles ; base 
leebly trisinuate, narrowly margined, apex strongly mar- 
gined at each side, not at all in the middle : scutcllum 
convex, strongly transversely triangular : elytra closely 
applied to — and wider than — the base of the prothorax,
