There was brought to me by Mr. T. H, Hill, of this city, one of our young collectors, a dragon fly captured at Delaware, a village a few miles west of here. It was one I had not seen before. On referring to Glover's Plates I found it there, figured and named. It is Hetœrina Americana, Fab., the Lestes basalis of Say, in the family Agrionidæ; a beautiful creature. Its most noticeable characteristics are the bright sangineous colour on the base of the wings, the clear copper colour of the thorax, and the brilliant gem-like ornamentation of the head.
