confused, declivity oblique, granules very fine, declivity and anterior area of prono- 
tum with long, erect hairs. 
-Norr.—This is at once distinguished from specimens identified by Eichhoff as X. 
affinis, and received from his type series, in the smaller size and moreshining front and 
also in the distribution.
