*92 (387). Bembidium vakiegatum Say, Trans. Amer. Phil. Soc, II. 1823, 



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

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

 with black markings (form patruele) ; antenna} fuscous, the 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; bind angles rectangular, strongly carinate. Elytra 

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

 dle; intervals convex. Length 3.5-4.7 nun. 



Throughout the State; common. Hibernates as imago. Often 

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

 In the form patruele 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 varicgalum. Both forms are common in Indiana, the dark 

 one being much the more so. 



93 (0252). Bembidium postfasciatum Hamilton, Can. Ent., XXV., 1S93, 



Form broad, dilated, slightly convex. Head and thorax coppery-bronze, 

 alutaceous ; elytra dull brownish-yellow with a small spot on third in- 

 terval, a cross-band about the middle and another near the apex blackish ; 

 legs dull yellow. Thorax subquadrate, about one-half wider than long, 

 as wide at base as apex; basal impressions broad, deep, bistriate; hind 

 angles rectangular, carinate. Elytra more than one-half wider than thorax, 

 deeply striate, the striae dilated at base, finely punctate; disk with a trans- 

 verse depression behind the scutellum. Length 5-6 mm. 



Southern fourth of State; frequent. February 11-July 28. 

 Taken along the Wabash and White rivers from beneath the bark
