groove. Scutellum scarcely longer than broad, trigonate, its apex 

 obtuse ; surface thickened, smooth and shining, impunctate. 

 Elytra broader than the thorax, subquadrate-oblong, their apex 

 broadly rounded ; convex, excavated below the basilar space, 

 punctate-striate, humeral callus thickened ; striae sulcate, rather 

 strongly punctured in front, less deeply punctured behind the 

 middle, interspaces thickened, every alternate one on the inner 

 two-thirds of the disk, and each one on the outer third, forming 

 a broad longitudinal costa^ those on the outer disk interrupted 

 in. the middle of their course, the remaining interspaces much 

 broken up by deep foveae, and irregularly vermiculate ; on the 

 anterior disk, placed on the costae, are four or five short fulvous 

 vittae.

Head remotely punctured ; front impressed with a longitudinal 

 groove ; epistome wedge-shaped, its anterior border slightly an- 

 gulate-emarginate, angles of the notch obtuse ; antennae filiform, 

 slender, black, four basal joints obscure fulvous, stained with 

 piceo- aeneous above. Thorax twice as broad at the base as long ; 

 sides rounded and converging from base to apex ; upper surface 

 coarsely and deeply but subremotely punctured on the disk, sides 

 closely covered with large deep punctures, interspaces on the sides 

 elevate-reticulate ; just behind the anterior margin is a shallow 

 transverse groove. Scutellum as broad as long, semiovate, its 

 apex subacute. Elytra broader than the thorax, parallel, apex 

 broadly rounded, lateral border narrowly dilated ; convex, slightly 

 excavated below the basilar space, deeply sulcate within the 

 humeral callus, the latter thickened ; striae strongly punctured,
