222 Mr. J. S. Baly's descriptions of 



slightly converging from base to apex, slightly rounded, 

 the hinder angles acute ; basal margin transversely trun- 

 cate, the medial lobe not bi-eraarginate; upper surface 

 obliquely excavated on either side, rather coarsely but not 

 closely punctured. Scutellum wedge-shaped, its apex 

 obtuse. Elytra narrowly oblong, sides moderately lobed ; 

 each elytron transversely excavated immediately below the 

 basal . margin, strongly impressed Avith eleven rows of
