Somewhat related to Midamus, from which it is distinct as fol­
lows : front elongate, sides narrowed below eyes j antenna1 tubercles
somewhat more closely approximate; pronotum not deeply exca­
vated on sides, at most only feebly impressed, unarmed ; elytra
more strongly attenuate apically, basal gibbosities elongate, mOl'e
strongly elevuted, disk distinctly granulate-punctate, humeri more
strongly projecting, the anterior margin straight, oblique j procoxae
uncate in male j and antennae about one and two-thirds times
length of body in male, third segment nearly one-half longel' than
first.
Moderate-sized, elongate-ovate, rather robust. Head with front elongate,
sides nearly parallel, feebly narrowed below eye; gena elongate; eye with lower
lobe ovate, about equal to gena in height; antennal tubercles sub.'lpproximate,
prominent, with an acute tooth at apex in male; entire head and pronotum covered
with coarse punctures. Pronotum transverse, sides straight, nearly parallel, at
base slighUy wider than at apex, unanned; apical transverse sulcus sinuate; disk
with five small tubercles. Scutellum transverse. EIytra moderately attenuate to
apices whieh are separately, narrowly rounded; basal gibbosities moderately elevated;
disk on base granulate-punctate; bumeri rather projecting, anterior margin
nearly straight, oblique, anglo with a large, obtuse tubercle, Prosternum simple,
narrowed betwC{)n coxae ; tnesosterna process moderately broad, apex emargin:l.te.
Legs rather short; procoxae globose, uncate in male; femora moderately clavate
beyond middle, profemora rugose nt base in male; meso- and metatibiae dilated
apically in male. Antennae about one ilnd two-thirds times length of body in male,
with scape strongly clavate from apical third, nearly at.taining middle of pronotum;
third segment sinuate, not slender, almost one-half again as long as first ; rest
