In the last few years, Lepidopterists have devoted a great deal of interest to the genus Euphydryas. This interest, however, has resulted in a great many valid and invalid names, but in little organization or understanding of specific variation and interrelation. Gunder (Pan Pacific Entomologist, VI, 1-8. 1929), in a carefully prepared and well illustrated paper, made the mistake of lumping all American species under five specific names, which is taxonomically incorrect, regardless of genitalic similarities (Pan-Pacific Entomologist, XI, 144, 1935).
