Head moderately produced between the eyes, vertex keeled in 
front, furnished posteriorly with an oblong fovea, orbital margin 
black; antennze nearly half the length of the body, moderately 
robust, subincrassate, two basal joints nearly equal, the first 
thickened, the second ovate, third half as long again as the 
second, fourth nearly one half shorter than the third, fifth and 
sixth each gradually decreasing in length, four last joints 
nearly cylindrical, seventh one-fourth shorter than the third, 
slightly thickened, and together with the four following joints 
forming a somewhat compressed indistinct club ; sutural articula-

broad as long at the base, narrowed from base to apex, sides dis- 
tinctly bisinuate, apical angle armed with a short, curved, obtuse 
tooth ; above subcylindrical, flattened and transversely excavated 
on the hinder disc; this latter portion smooth, nearly impunctate, 
remainder of the surface closely covered with large deeply-im- 
pressed punctures; basilar lobe broadly truncate, its surface oblique, 
transversely grooved. Scutellum transverse at the base, sides 
narrowed towards the apex, the latter obtusely truncate. Elytra 
broader than the thorax, narrow, subparallel in front, very slightly 
dilated towards the hinder angle, the latter scarcely produced; lateral 
border very narrow, very remotely armed with small teeth ; apical 
border moderately dilated, its edge obtusely rounded, coarsely
