OF PHILADELPHIA. 161 



tonnas brown : thorax pale rufous, loniritudinally oblong, nar- 

 rowed towards the base ; two very slightly indented dots before 

 the middle, and a hardly perceptible one near the base : elytra 

 confluently and minutely punctured, pubescent : tibia pale. 



Length three-tenths of an inch. 



The elytra have some faint appearances of impressed lines. 

 This may probably be the Arci/dalis ihoracica of Fabr. ; it is 

 certainly allied to his X. sanr/uiiiicuUis. [273] 



[Belongs to Asdcra, and is the Fabrician species first mentioned.
