Cassino tabulated several characteristics supposedly distinguishing C. m. manitobensisfrom nominate  C. blandula Hulst, 1884. On the dorsal forewing these included: a darker and more distinct postmedian band; a light to absent brown scaling distad from the postmedian band; and a lighter and bluish ground color, such that “the whole effect of the superiors is a bluish tint quite unlike that of  blandula, the scales of which are more brownish.” We have examined specimens of C. m. manitobensis(including paratypes) and nominate  C. blandulafrom across the Nearctic, and find that the characteristics ascribed to C. m. manitobensisoccur sporadically throughout the species’ entire geographic range, especially in females, and see little merit in retaining the name  manitobensis. Exemplary localities where specimens often show  manitobensischaracteristics include the vicinity of Chicago, Illinois, and the eastern seaboard of Maine and maritime Canada; the same characteristics also appear regularly in what we presently consider to be  C. blandulapopulations from lowland coastal areas in the southeastern USA(e.g., notably around Gainesville, Florida). These lowland  C. blandulapopulations are among the most morphologically variable known: some Floridian specimens (especially females) are nearly identical to types of  C. manitobensis, whereas others have the entire forewing pattern obscured by brownish black, and numerous intergrades occur. In many respects, the extreme variation in these southeastern  C. blandulapopulations is analogous to the extreme infrapopulational forms of both  C. connubialis Guenée, 1852and  C. crataegi Saunders, 1876seen from the same geographic region.
