Stenotaesia discoidalis, sp. n. 



Atra, depressa, supra OTpaca ; tJiorace quadrato, Umbo fulvo ; elyirls de-

 trartsve7'sim posit is atris ; corpore subtiis lovgeflavo-ginseo-pubescenti ; pedibus 

 piceis. Long. Q\ — 7 lin. 



Clypeus ratlicr thickly and obscurely punctured, only slightly emarginate at the 

 apex. Thorax one-fifth broader than long, rather flat, obliquely but not much nar- 

 rowed in front of the middle, behind the middle the sides are nearly parallel, the 

 anterior angles are prominent and acute, the posterior angles nearly rectangles but 

 blunt, the base arcuate, black, with all the margins orange-yellow. Scutellum

 legs are rather more robust, and the posterior tibise have a slight projection on the 

 inner side at a little distance from the apex.
