lateral margin with a yellow fovea; disk sparingly 
punctured, the punctures more crowded on ‘the sides. 
Elytra parallel on the sides, conjointly rounded at the 
apex; convex, distinctly excavated below the basilar 
space; closely rugose-punctate, transversely rugulose 
below the basilar space; longitudinally costate at the 
apex, obsoletely costate on the basilar space, the latter 
slightly thickened.

Head coarsely punctured, front and vertex with a 
longitudinal excavation ; antenne slender, the four lower 
joints rufo-fulvous, the fifth to the seventh nigro-piceous 
(the rest broken off). Thorax twice as broad as long; 
sides rounded, armed with three short subacute teeth ; 
disk coarsely and irregularly punctured, broadly but 
not deeply excavated on either side. Hlytra broader 
than the thorax, very slightly dilated behind the middle, 
their apices conjointly subangulate-rotundate ;, above 
convex, slightly excavated below the basilar space; each 
elytron with eight strongly raised longitudinal cost, the 
interspaces between which are very deeply punctured ; 
on the anterior two-thirds of the disk and on the outer 
margin these punctures are irregularly arranged in 
double rows, the interspaces being irregularly wrinkled ; 
near the suture and near the apex the punctures are 
uniseriate, the apices of the third to the fifth cost con- 
fluent and only forming a single ridge.
