in profile subacute before the eyes distinctly produced. Frontal 
costa behind the antennae very frequently sinuate. Antennae 
very short, not at all reaching the humeral angles, often shorter 
than the head, a little enlarged, consisting of twelve to fourteen 
articles, inserted scarcely before the eyes. Pronotum truncate in 
front or angulate, posteriorly acute very frequently abbreviated, 
dorsum above tectiform rarely depressed, between the shoulders 
a little ampliate ; humeral angles strongly obtuse ; posterior angle 
of the lateral lobes slightly turned obliquely outwards, inferior 
lateral margin straight or base subsinuate. Femora entire or 
rarely femoral carinae subsinuate ; posterior tibiae linear, slender, 
but ampliate near the apices, carinae serrulate, short spinose or the 
apical fifth of the inner carina unarmed ; first article of the 
posterior tarsi elongate, distinctly longer than the third.

Body slender, granulate punctate. Vertex viewed from above 
equal in width to one of the eyes, front margin subtruncate, 
advanced about as far or scarcely beyond the eyes, carinulae 
arcuate abbreviated, very slightly elevated laterally, side margins 
very little convergent forward, middle carinate produced in front, 
on either side little longitudinally depressed ; vertex viewed in 
profile advanced before the eyes. Frontal costa viewed in profile 
convex behind the antennae, viewed in front moderately sulcate, 
the rami slightly diverging toward the base ; face sensibly retreat¬ 
ing. Eyes small globose barely exserted. Antennae rather short, 
slender filiform. Pronotum truncate in front obtuse subangulate, 
posteriorly long subulate acute strongly extended beyond the 
apex of posterior femora; dorsum between the shoulders tecti¬ 
form ; humeral angles widely obtuse ; median carina of pronotum 
elevated acute compressed, percurrent, anteriorly longitudinally
