Excessive Injury by a Beetle in Russia.—We noticed recently the accounts given in Russian newspapers of the mis- chief which is being done by locusts. One of the most destructive insects in South Russia is the beetle called by naturalists Anisoplia aiistriaca, and by the rural popu- lation of Kherson, Gonzka. This insect first appeared in 1865 in the Melitopol dis- trict, but there is nothing known as to how and whence it came, as it had never been heard of in any other part of Russia or bordering countries. The form of the insect is oblong and slightly convex; it is of the size of a grain of ricinous seed and of a cinnamon color. The change from egg to larva, and from larva to a full-grown beetle, takes nearly two years. The female lays her eggs about two inches deep in the earth, and the grubs, after leaving the eggs, grow very slowly, live the whole win- ter in the earth, finding nourishment in the soil, and then become more developed, but remain as grubs the following summer and winter; then, on the approach of spring, they rise to the surface of the ground, where they accumulate. As many as ten bushels of the beetles have been collected from one acre of wheat. They fly from ear to ear, and do not (^uit it until it is destroyed. They are capable of making long flights from one Government to another. Last summer a mass of these bee
