In beetle state they feed on leaves and shoots of various plants, amongst which Vines, Baspberries and Strawberries may especially be men- tioned, though unfortunately the list might be much length- ened,^ and sometimes includes field root-crops, of which an especial instance came under my notice in 1885, when the two above-mentioned kinds greatly injured twelve acres of Mangolds. On June 10th Mr. Warner wrote to me from the Nurseries, Leicester Abbey, regarding an attack of brown beetle-Hke insects, which appeared, as he said, to be " almost omnivorous," and, after giving a list of attacked plants, further noted, " They arc now materially^ injuring twelve acres of Mangel ; From the specimens accompanying these proved to be Otiorhynchus sulcatus and 0. picipes. I have also had twigs of Eed Currant, Cob Nut, and Damson (as well as of Easpberry), sent with specimens of beetles' accompanying, to show the "sad havoc" made in fruit plantation by the Otiorhynchus picipes: as many as 105 of the beetles were reported by the sender as having been found on the stem of one Cob Nut tree. The two species mentioned above as well as the 0. tenehri- cosus, or Eed-le
