Description in Seitz

P. krueperi Stgr. (20b) occurs in Greece, Asia Minor, Persia and other districts of Western Asia.This species differs from its allies in possessing on the forewing a black subapical costal spot and several, well separated, black distal marginal ones. In the summer-form, which is name-typical, the underside is white with yellowish margins, while in the spring-form, vernalis Stgr. (20b), the larger proximal portion of the hindwing beneath is greenish grey. — The Central -Asiatic spring-form, verna Gr.-Grsh., is whitebeneath, but bears dark markings. — The Pamir form, mahometana Gr-.-Grsh.[now species Pieris mahometana (Grum-Grshimailo, 1888) (northeastern Afghanistan and Pamirs)], is above margined with black and beneath much darker. In the female the black spots are enlarged and partly confluent. ^[3]
