Batavia, N. Y., July 31 (Gerhard) . Known from Ontario and 

 New England west to Pennsylvania. "In western New York 

 it breeds abundantly on mountain maple, Acer spicatum Lam., 

 and to some extent on dockmakie, Viburnum acerifolium L., and 

 alternate-leaved dogwood, Cornus alternifolia L. It is also fre- 

 quently attracted to the flowers of poison hemlock, Conium 

 maeulatum L., for feeding, and in this way 58 specimens were 

 taken on July 31." {Knight).
