Sure is
Moved from Bolbocerosoma. Looks like its markings are a bit stronger, but you can count the seven dorsal striae on the elytra, which makes this the only possibility in the upper Midwest. The other species with the seven striae (tumefactum) is more eastern, only getting as far west as Ohio to my knowledge.
