I submit herewith descriptions of 3 species and 3 varieties of Canadian diurnal Lepidoptera, speciments of which have been in my collection for many years, and of which a continued study convinces me that it is wise to characterize them for the benefit of other students of Canadian butterflies. It is possible that some of these may be only local races, but they are so constant that I believe them to be well worthy of recognition. In describing these forms, I have endeavorued to compare them with their nearest allies, as a description, even when accompained by a plate, is more intelligible when a new form can be compared with a well-known standard.
