records of its occurrence. However, in States where the map shows 
only a single record, a search for specimens would doubtless show the 
species to be present generally. 
FOOD PLANTS. 
Desmiafuneralis feeds principally on the wild and cultivated grape. 
It has been collected on fox grape, Vitis labrusca; southern fox grape, 
Vitis rotundifolia; and Vitis cordifolia. 
Generally speaking, all varieties of cultivated grapes are liable 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

Agawam, Brighton, Excelsior, Grein's Golden, Highland, Herman, 
Israella, Jefferson, Jessica, Mary Ann, Lady Washington, Merrimac, 
Mason Seedling, Requa, Rogers, and others losing more than three- 
fourths of their foliage, while others lose about one-half. 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 Desmiafuneralis, Titus 
having found it on Virginia creeper (Parthenocissus quinquefolia [L.]) 
near Somerset, Md. He also found two varieties of redbud, Cercis 
canadensis and Cercis cMnensis, as hosts, in the Department of Agri- 
culture grounds at Washington, D. C.
