Argynnis cybele Fabr. is generally distinguished from the closely allied A.aphrodite Fabr. by the following two features : (I) the veins of the central area of the primaries in the male sex are thickened by sex-scales; (2) on the underside of the secondaries the yellow submarginal band is broad and clear and not invaded by the red-brown color of the basal section.

While collecting in Nova Scotia during the months of June aud July, 1934, at South Milford and at White Point Beach, near Liverpool, I took a series of an Argynnid which struck me at the time as strongly resembling aphrodite on the underside but which on the upperside of the forewings showed the heavy sex-scaling on the veins in the male sex which would consequently indicate cybele.
