These sure look like Sawtooth Grain Beetles, Oryzaephilus surinamensis, to us, though there is not enough detail to be certain.  They might also be the closely related Merchant Grain Beetle, Oryzaephilus mercator, and according to BugGuide:  “Adults and larvae feed primarily on cereal products, particularly oatmeal, bran, shelled sunflower seeds, rolled oats, and brown rice; usually associated with oilseeds and less with cereal grains and in most regions damages processed cereals, especially those with high oil content; also feeds on seed-borne fungi”  You may compare your image to the images posted to BugGuide.
