An illustration of this species (fig. 6) and a short notice of it is pre- sented, for the reason that it is one of the few insects which derive their common names from the beet, and })ecause it is destructive to sugar beet in Europe. There is, moreover, some likelihood of its becoming a pest in our own country if it should ever be Nk ^ able to obtain a permanent foothold here. It f J^A^ € ig reported as having been observed in Cali- fornia in 1894, but as we have hoard little of the insect since that time some doubt exists as to its actual establishment in America. It ranges through Europe and in Asia from Persia to Siberia, and it may be that it is destined to become cosmopolitan. Therefore beet growers should be warned against it. In Europe this beetle feeds on lambsquarters, Atriplex, and related plants, but when these plants become exhausted it devastates large areas of sugar beets. There are said to be two generations of the beetles produced annually, one appearing in August, the other in the autumn. The beetle is about one-fourth of an inch long and yellowish gray or pale green in color. Remedies.—The same remedies advised against other leaf-beetles would apply to the present species.
