[1] Seitz-bryoniae (21c), which inhabits the Alps, Northern Scandinavia and the mountains of Asia Minor; the male of the latter is rather more narrow-winged than napi-males, not bearing any markings on the forewing above except the blackish apical and basal areas; the female has a yellowish ground-colour, which is however more or less suppressed by the great extent of the dark scaling situated along the veins.

Among the females there occur specimens in which the discal spots and the vein-streaks of the forewing are strongly obsolescent, there being consequently no prominent marking; we name this form ab.

obsoleta nov.; individuals in which the yellowish ground-colour, especially on the forewing, is almost entirely suppressed by the greater extension of the dark scaling may be named ab.

Other less evident morphological characteristics are currently the subject of discussion among entomologists, given that their relevance appears only in restricted populations.The wingspan is between 4 and 4.4 cm.

The type locality of the nominate form is the Alps, where it is found at considerable altitudes (up to 2000 m) and has only one generation per year.

Subspecies neobryoniae, closely resembles the Carpathian populations, and is found in the southern parts of the Alps and ssp.
