middle of the inner orbit. The scape is cylindrical. — The 
prothorax has no glossy tubercle at the sides, and the 
pronotum shows more transverse wrinkles. — The elytra 
are gradually narrowed towards the apices which are 
separately rounded; the base is nearly straight and the 
shoulder angles are provided with a ‘strong glossy black 
tubercle; between this tubercle and the extreme base of 
the elytral epipleurae a distinct keel is present. — The 
elytra are covered with regular longitudinal black lines, 
formed at the base by glossy granules which soon are 
replaced by punctures which become smaller and smaller 
towards the end. At one third of their length the elytra 
are depressed across the middle and this depression is 
regularly bent forward towards the shoulders. — The 
pygidium is narrowly emarginate in the middle, the lateral 
angles broadly rounded; the last ventral segment is very 
broadly emarginate (subtruncate) at the end.
