For many years the authors have been studying the butterflies of the Riding Mountains and of the Sand Ridge and have found numerous forms and races new to science. In a paper read some time ago at a meeting of the Pennsylvania Academy of Sciences, many of these forms and races were described. To make these descriptions available to more students, Dr. J. McDunnough suggested that we use the “Canadian Entomologist”. All the holotypes will be deposited in the Canadian National Collection and the allotypes in the Carnegie Museum.
* The Sand Ridge is a region of gravel ridges, covered with oak thickets and prairie vegetation, situated about ten miles northeast of McCreary, Manitoba. It is not far from the eastern border of Riding Mountain National Park, and it should not be confused with the town of Sandridge which is situated about fifty miles north of Winnipeg. Editor.
