1. Papilio Philenor.

On 21st May, 1881, I saw a female Philenor fluttering about a low plant in the edge of the woods near my house. Apparently it was a vine just out of the ground—some four or five inches high—and three eggs were laid on the stem. I sent the plant to Mr. Scudder for determination at the Botanical Gardens, but he reported that there was not enough of it for that purpose.

On 1st Aug., I saw a female coursing over the hill side, alighting on various species of plants for an instant; sometimes on clover heads or other flowers, then flying again in short circuits, touching a leaf here and there. Perhaps it was ten minutes before she lingered on one plant longer than usual, though then but for three or four seconds, and I found on examination three eggs laid on the stem just below the terminal leaf. The plant was of the same species I had noticed in May, and I dug it up and planted it in the garden. When at Cincinnati, at the meeting of the A. A. A. S., I learned from Dr. H. S. Jewett that this must be Aristolochia serpentaria, a common plant about Dayton, O., and later I received from him several dried examples of it.
