(= lama Stgr.) being dull grey and smaller than typical, while askolda Oberth. from Askold Island [now ssp.] is a large brown form; — ab. calabrica nov. [Warren] is a very large form; the forewing with pale blue-grey ground colour, irrorated and suffused with dark grey in basal half (in one example all over the forewing), with all the lines and stigmata strongly expressed in black and pale grey, the submarginal line in particular being continuous, black and dentate, the hindwing is likewise much darker, with all the veins, the cellspot, and outer line wellmarked; a series of four males and ten females, in the Tring Museum, taken on the Sila Mts., near Botte Donata, Calabria, 800–1000 m, July 1907, by Dr. O.
