. In Seitz it is described- Upper surface agreeing with that of '' larydas'' Cr. (71 h); on the forewing beneath in ''larydas'' the white marginal line of the first basal double spot is distally almost rectilinear, proximally beginning from the middle bent inwards; in ''abrupta'' the proximal line terminates on the median vein, the distal line forming a small bow distally somewhat above the median vein and ending on this vein; the whole lower part of the basal spot is thus absent; the central spot between vein 1 and vein 2 is in bordered with white like the others, in ''abrupta'' there is only a brown, pointed spot without a light marginal line; the marginal spot following then between vein 1 and vein 2 is in abrupta not bordered proximally, but only separated from the central spot by the light ground-colour; hindwing like in ''larydas''. Expanse of wings: 25 mm.Described according to a single specimen. As the only difference between this form and ''larydas'' is the formation of the spots in area 1 b on the forewing beneath, we may suspect it to have been founded upon an abnormal specimen in which the development of the marking of this area has been impeded.
