We were fortunate in taking a very peculiar pair of Colias philodice this summer. They were captured at Edgartown, Mass., in a litrle salt marsh, August 10th and 14th respectively, and, though hatched during the hot wave, we believe are blood relations — part of a sport brood.
Many specimens were examined at the time, but no other departures from the type found.
