Moderately broad, slightly convex. Ik-ad and thorax blackish-bronzed. 

 alutaceons; elytra black \vith a few dull yellow markings, or dull yellow 

 with black markings (form putruclc) ; antennae fuscous, tlie basal joints 

 paler; legs reddish-brown. Thorax subquadrate, as wide at base as apex; 

 sides slightly curved in front, distinctly sinuate behind; basal impressions 

 broad, deep, bistriate; hind angles rectangular, strongly cariuate. Elytra 

 one-half wider than thorax. stri;e entire, distinctly punctate to behind mid- 

 dle: intervals convex. Length 3.5-4.7 mm. 



Throughout the State; common. Hibernates as imago. Often 

 attracted in summer by eleetri- light. February 26-December 25. 

 In the form pat rude the ground color of the elytra is dull brown- 

 ish-yellow with a humeral spot, a narrow line along the suture and 

 three more or less interrupted, sinuous cross-bars, black. In a 

 large assemblage of specimens these dark markings gradually be- 

 come broader and more extended until the black predominates, the 

 elytra being then spotted and banded with dull yellow as in the 

 typical rarityai mn. Both forms are common in Indiana, the dark- 

 one being much the more so.
