 of the eye ; funiculus seven-jointed, first and second joints elongated, 

 obconical, the former the longer and stouter, joints three to seven very 

 short, almost rounded ; club stout, elongate, pubescent, articulate. Eyes 

 large, much depressed, oval, longitudinal. Prothorax longer than broad, 

 very regularly conical, truncated at base and apex. Scutellum very 

 small, variable. Elytra rather short, navicular, compressed, with a long
