Judging by the genitalic figure (based on an Ottawa male), given by Heinrich in his revision (fig. 276) and by the remarks in the text (p. 12) the species has been — at least partially — misidentified by this author. Clemens' type (selected by Fernald) is a specimen from Baltimore, Md., in the Academy collection at Philadelphia; the specimcn is unfortunately without abdomen but has recently been very carefully examined by Mr. T. N. Freeman who selected a male specimen from Oak Station, Pa. (Marloff) as almost exactly matching this type.
