ardens, cunealis, par, sordidus, bidens, nu- 
bilus, varius, compar, lucidus, percursus, 
rubidus and triops. 
Host Prants.—Most frequently wild 
grape (Vitis sp.), but may occur on culti-

on other woody plants. Illinois specimens 
were collected on grape, box elder (Acer 
negundo), willow (Salix sp.), hop tree 
(Ptelea trifoliata), hickory (Carya sp.), 
hawthorn (Crataegus sp.), dogbane (4 po- 
cynum sp.) and dogwood (Cornus sp.).
