In Ent. Mo. Magazine for August, 1878, is a paper by Dr. J. A. Osborne, respecting a discovery made by him oi the made by which the larvæ of the Nymphalidæ attach the chrysalis to the button of silk, and which is “altogether at variance with the account given in Kirby and Spence and other works.” Dr. Osborne relates : “In watching the transformation of V. Urticæ, I found that the chrysalis was attached to the old skin of the caterpillar by a membrane sufficiently strong and permanent to support the insect during the critical last moments of pupation, and fully explaining why it does not fall down when the tail of the chrysalis is withdrawn from the old skin and thrust up to be attached to the silk.”

Sphinx catalpae Boisd., pl. 2, figs. 1, 2 (1874).

This species is represented in the Collection of Mr. E. L. Graef by an example from Florida. It is smaller and darker than D. undulosa or D. Hageni, of a uniform butternut or olive brown tint.

Emydia ampla, n. s.

♀. Wings large, body linear, slight. Eyes naked ; palpi exceeding the front ; maxillæ weak.

I have usually taken this species at the same place, about one or two specimens a year, and always within ten yards of the place where I first took it six years ago. The trees in the immediate vicinity were Gleditschia triacanthos, Ulmus americana, Prunus serotina and Celtis occidentalis, but it may have fed as larva upon some weeds or shrubs growing near. All of my specimens were taken about the 8th or 10th of July. This year, however, I have captured (June 14th) two specimens (perfectly fresh) on Gleditschia triacanthos at another place, where the nearest tree was Celtis occidentalis, growing some thirty yards away. Its larva and food plant, however, are not yet by any means certainly ascertained.
