Our largest Eastern species. Thorax emarginate in front, angles distinct, broader 

 than long, somewhat broader at base, sides feebly sinuate. Antenna' slender, outer joints 

 feebly compressed; last three joints smaller and gradually decreasing. Elytra faintly 

 striate, shining with indistinct metallic stripes. Propleurae coarsely and confluently punc- 

 tured. Apex of last ventral segment with a broad hairy depression ; in the females the 

 depression is longitudinal and smaller. 



Length .50-.70 inch. 



A species of wide distribution.
