Two New Variants in California Colias eurytheme (Lepidoptera, Pieridae)

Abstract

<br />Two apparently new variants of the highly variable C. eurytheme complex are deserving of description. Names have not been applied inasmuch as the author feels that it is not desirable to propose names which would inevitably be placed as synonyms since their grade would so definitely be below that of the subspecies, the lowest category recognized by the International Rules of Nomenclature.
