 The short head, with its peculiar foramen,

 malabaricm. lobes, which appear rather flattened externally, 

 owing to the projection of the eyes in front, 

 are useful characters for the determination of this species.

Shining pitchy black ; head longer than broad, subtriaugular,

 at its apex ; prothorax a little longer than broad, furnished on its 

 disc with four subequal ridges and five furrows ; elytra with seven

 11. taprobance. From the former it differs by the more irregular 

 breadth of the prothoracic ridges, the lateral ones being reduced

 the antennae are proportionally thicker. It is a larger species 

 than R. taprobance, with the intervals between the thoracic ridges 

 much broader and the ridges themselves differently shaped ; the
