 genus.

I took this insect in the Metropolitan district. It differs from any described 

 species in being sub-apterous, and in the form of the striae of the mesonotum, 

 which are nearly entire, and regularly curved outwards from the basal foveao, 

 instead of proceeding longitudinally towards the middle of the disc. It approaches 

 nearest to Jlavipes, Thoms. Also found by Mr. Walker.
