Can there be two Antispila miners of the Dog-wood? Either there must be, and my specimens are specifically distinct from this species, or Dr. Clements' description is strangely erroneous in at least one particular, viz., the color of the fascia and streaks, which he says are golden in cornifoleilla, but which are silvery white in my specimens, all of which six in number–agree exactly in ornamentation, and all but one of which are bred specimens. The species of the genus generally resemble each other very closely, and some recognized species do not differ from each other more than my specimens do from Dr. Clemens' description.
