supra lateral! longitudinali vix distincta praeditus, in medio ab apice 

 basi distincte carinatus, ibi baud transversim impressus, creberrime 

 punctulatus ; elytra ( S ) ovalia, postice sensim angustata, convexa, 

 apice fere conjunctim rotundata, propter suturam baud depressa, at 

 impressione sub humerali parva utrimque praedita, vel (?) ad latera 

 a basi medio valde ampliata deinde perspicue sensim angustata 

 apiceque conjunctim acuminata, supra convexa, sutura fere a medio 

 ad apieem alte carinata ibi fere recte decliva compressaque ; pedes 

 graciles.

The difference between the two sexes is very great ; in the 3 the 

 elytra are regularly ovate and convex, and the suture normal, while 

 in the 5 , which is broader by one-third than the S . the suture 

 ending almost vertically at the apex is raised and compressed 

 almost laminate, beginning at a short distance from the two very 

 deep and broad dorsal fovese, and somewhat in the shape of a wedge.

 baud longior, postice autem antice latior, ad latera ab apice pone
