Geographical Variation and Racial Structure of Argynnis callippe in California

Abstract

The geographical distribution and variation of Argynnis callippe in California and adjacent regions is described with a genetic viewpoint by which it is assumed that populations are different because they have different genes or different frequencies of genes. Maps are given which show that only two of six distinctive characters are always completely correlated, the distribution of the others bearing no definite relation to the others. Additional data are given to support the conclusion reached in a former paper that most characters distinguishing geographic races are adaptive in character, but that this adaptiveness is generally of a concealed nature. Note. Since the above was in process of publication the following important information has been obtained. The gap in geographical distribution between the southern and northern parts of the north Coast Range has been partially filled by material from Comptche, Mendocino County, California. This population would be located on the map directly northwest of t...
