Form cimbiciformis Stephens, Plate II, Fig. 6, female.

This is the largest and the commonest species of the genus. It may easily be recognized by the figures given on Plate II. It is subject to considerable variation. The form cimbiciformis is distinguished by the absence of the dentations on the inner side of the marginal brown band of the fore wings. It has been obtained by breeding from the eggs of H. thysbe, and thysbe has been bred from it. It is a dimorphic form of the species. The caterpillar of H. thysbe feeds upon Viburnum and allied plants. The insect ranges from Canada and Nova Scotia southward to Florida and westward to the Mississippi.
