 Moderately broad, slightly convex. Head and thorax blackish-bronzed, 

 alntaoeous; elytra black with a few dull yellow markings, or dull yellow 

 with black markings (form putniclc) ; antenna; fuscous, the basal joints 

 paler; legs reddish-browu. 1'horax subquadrate, as wide at liase as apex; 

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

 liroad, deep, bistrlate; hind angles rectangular, strongly carinate. Elytra 

 one-half wider than thorax, stride entire, distinctly punctate to behind mid- 

 dle; intervals convex. Length ;i.r,^.7 mm. 



Throughout the State; common. Hibernates as imago. Often 

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

 In the form patruplc 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 

 laifie assemblage of specimens these dark markings gradually be- 

 come broader and more extended tmtil the black predominates, the 

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

 typical variegatum. Both forms are common in Indiana, the dark 

 one being much the more so.
