Vertex strongly but not very closely punctured, shining 
black ; lower face, together with the inner orbit of the eye, 
obscure fulvous, encarpe and carina piceous; encarpe sepa- 
rated from the front by a deep transverse groove ; carina oval ;

sides broadly margined, reflexed, nearly straight and parallel 
behind the middle, thence slightly rounded and converging to 
the apex, anterior angles produced anteriorly, thickened, 
obtuse ; basal margin slightly bisinuate on either side, the 
median portion opposite the base of the scutellum also slightly 
sinuate ; upper surface shining, nearly impunctate, longitudi- 
nally excavated on the reflexed lateral margin, obsoletely 
elevated on either side just to within the latter, the middle 
portion of both the apical and basal margins narrowly edged 
with black. Scutellum subtrigonate, its apex rounded, de- 
pressed. Elytra broader than the thorax, broadly ovate, 
moderately convex, longitudinally depressed along the base of 
the suture, distinctly punctured ; inflexed limb flavous. Basal

thence rounded and converging tothe apex, anterior angles pro- 
duced into a short obtusely truncate tooth ; upper surface mi- 
nutely punctured. Scutellum trigonate, its apexobtuse. Hlytra
