GALERUCELLA NOTULATA SAY, THE RAGWEED LEAF-BEETLE.

The writer has taken this species in Middletown, Connecticut, but not in Maine. As the preferred host plant is the Roman wormwood, Ambrosia artemisiaefolia L., a common weed

throughout the state, this beetle probably will eventually be found in the state. There are 2 generations each year in Connecticut, the adults of the second generation hibernating.
