This species is very common in Oklahoma and apparently in Texas. It restricts itself to areas of virtually pure sand where it replaces Canthon laevis laevis (Drury). It is very similar to laevis, the types of which came from New York and Maryland. Our New York and Pennsylvanian specimens of laevis are distinctly coppery over the entire dorsal surface and have the granules of the dorsum relatively close. Specimens from Illinois, Kansas, Oklahoma, and Alberta are similar and are typical laevis in every respect. Specimens from South Carolina and Florida show no coppery luster.
