  ## Description in Seitz
  
  amurensis L. amurensis Men. (27 g) from the Amur, North China and Japan, is especially characterised by the elongate forewing. The upperside is white, the male having a larger blackish subapical patch, which is absent from the female or is much smaller and less well marked; the underside is white, with a yellowish apical spot on the forewing and grey shadowv markings on the hindwing. — The spring-form vernalis Graes. is smaller, being darker beneath. — vibilia Janson[ now L. sinapis ssp. vibilia Janson, 1878], from North Japan, has more pointed wings than amurensis being similar to duponcheli in markings and colour. — morsei Fenton is apparently an aberration in which the subapical spot of the forewing above is less developed.
  
  ## Biology
