It will thus readily be seen that the year liH)() was not necessarily an exceptional one as regards attack by this tiea-beetle in the East, as much of the injury that has been attrib- uted to other species mentioned ma}' often in reality be due, at least partially, to the spinach tlea-beetle. August 16, 11»(H), the wa'iter observed nu- merous beetles of this species,^ dead and living, under plants of saltbush belonging to different species of Atriplex, growing on the experimental plats on the Department grounds. Under these plants the ground was fairly strewn withlivingand dead beetles, and larvtv were found, though somewhat sparingly at this time, on the foliage. The species o^f Atriplex upon which this tiea-beetle was observed include A. semihaecation^ A. Jioloc<trpa^- A. veluttnella^ and an undetermined form—all cultivated varieties, and useful as forage plants. Numerous nymphs of the wheel bug {Prl^fnidus ) were observed during the early part of June on beets infested with this tiea-beetle. Such as were seen feeding had the larva^ of the beetle impaled on their beaks. The Eggplant Flea-beetle {Ejyifrixfuscnla Cr.).—Injury by this flea- beetle (tig. 30) which has been treated somewhat fully in Bulletin 19, n. s.
