 nuated and incurved to the base ; surface convex, varied with light 

 and dark brown, and with two black vittse each interrupted in 

 the middle ; side, below the tubercle, black, shiny. Elytra short 

 for this genus, broad at the base, gradually attenuated to near 

 the apex, thence suddenly attenuated, making the truncated apex 

 narrow; sutural spine short, external one elongated; shoulders 

 advanced and rounded, lateral carina strongly pronounced and 

 polished, deflexed sides coarsely punctured and with a smooth 

 carina; surface longitudinally convex, setose, and punctured; 

 two short, rugose, slightly elevated carinse near the base, and 

 one longer and smoother along the disk; the colour is brown 

 varied with ashy, near the scutellum is a dull blackish patch, and 

 behind the middle is an oblique black streak ; the anterior part 

 of the disk is ashy, and there is a triangular ashy spot near the 

 apex. Body beneath black, with grey pile ; a row of ashy spots
