The Southern Chipmunk occurs within our limits in southern 
Illinois. Howell records it from Olive Branch, Wolf Lake, Woodlawn 
and Olney, and I have seen a specimen taken in Macon County, in the 
central portion of the state. Its habits are similar to those of the 
northern race, Tamias striatus griseus.
