Subcylindrical, robust. Black, subopaque; thorax with sides and a 

 narrow median line usually red; elytra with a line at base and usually a 

 number of oblong spaces on the broken intervals dull yellow ; antenme red- 

 disli-brown at base, dusky at apex; femora often with a yellow spot. Tho- 

 rax densely, coarsely and deeply punctured, often with a portion of a smooth 

 median line; hind angles obtusely rounded. Elytra with coarse, confused 

 punctures over the greater part of the surface, the rows visible only on sides 

 and behind middle. Length 3.2-4 mm. 



Throughout the State; scarce. June 1-July 9. Occurs on 

 flowers of Jersey tea and on foliage of the false indigo, Baptisia 

 leucantlia T. & G. The elytra, and sometimes the entire body, are 

 wholly black. In the latter instance the name var. nigriniis (2086a) 

 is herewith given to distinguish them from the other black species, 

 ninrosns and carbonarius. Tho punctures of thorax arc much 

 coarser than in the latter.
