Desmiafuneralis feeds principally on the wild and cultivated grape. It has been collected on fox grape, Vitis lahrusca; southern fox grape, Vilis roiundlfolla; and Vitis cordifolia. Generally speaking, all varieties of cultivated grapes are Hable to attack, though there is some evidence to indicate that the larvae may show discrimination. According to Woodworth (14) this distinction made by the larvae between varieties is quite marked, the varieties.

The writer has found in Virginia that the Clinton, Duchess, Martha, Moore's Early, and Amber varieties are particularly attractive to the insect. Varieties with tough leaves are less attractive than those with more tender foliage. Plants other than the grape are fed upon by Desmia fiineralis, Titus having found it on Virginia creeper (Parthenocissus quinquefolia [L.]) near vSomersot, Md. He also found two varieties of rodbud, Cerds canadcmii^ and Caris chinensis, as hosts, in the Department of Agri- culture grounds at Washington, D.
