 pubescent, not toothed, apical joint of maxillary palpi fusiform, 

 slightly truncate at tip ; body very convex ; scutellum very long, 

 lanciform, reaching almost to one-fifth of the length of the elytra 

 the striation of which is similar to that of Aphodlus ; anterior tibiae

 scutellum very long, parallel for two-thirds of the length, and 

 lanceolate for the other third, it is irregularly but very closely 

 punctured, and somewhat coriaceous ; elytra very convex, deeply 

 punctato-striate, intervals convex but not tectiform, smooth, im-
