Dr. Austin H. Clark recently drew the attention of Dr. McDunnough to the fact that specimens of Incisalia niphon from Canada differ in several respects from niphon as it occurs in Florida (type locality) and other southern localities. Dr. Clark has kindly furnished a female specimen of niphon, taken at Mt. Vernon, Va., which upon study I have found to agree quite well with typical niphon as figured by Hubner in the Zutrage Exot. Schmett. figs. 203 and 204.
