and two discal, the external interspace with two rows of large 

 punctures, the others with one row. Abdomen coriaceous,

Eleusis mjobergi n. sp. 



Entirely black. Very shining, very finely and very 

 sparingly punctured, ground sculpture very fine : head in 

 both sexes large, orbicular; thorax broadly depressed on the

 less distinct, shorter elytra and longer, more slender antennfp
