Antennce with joint 7 of the fuiiicle a little longer and more 

 slender. Prothorax with the upper edge of the lateralpale marking 

 well defined. Ehjtra with the dark patches absent or small, the 

 basal transverse impression shallower and therefore the dorsal 

 curvature flatter, the sulci not broader than the intervals, the 

 punctures in them smaller.
