One year ago I gave at the Boston meeting of the Association for the Advancement of Science the results of some experiments in the use of London purple to destroy the codling moth larva, and bisulphide of carbon in fighting the cabbage maggot and squash borer. These experiments have been repeated the present season, and with results no less favorable than those reported one year ago. I think it is an established fact that the methods recommended are valuable. They not only seem reliable, but they promise to be the cheapest and most desirable modes that can be made practicable on all occasions.

The above is the title of a paper received from the author, and published in the Proceedings of the Zoological Society of London (February 15th, 1881), in which his Lordship characterizes three new genera : Phryganeopsis—one species, P. brunnea; Aræolepia—one species, subfasciella; and Euceratia—two species, castella and securella. He also describes as new Calantica polita, Plutella interrupta, P. albidorsella and P. vanella; Cerostoma falciferella, C. cervella, C. sublulella, C. dentiferella, C. canariella and C. frustella; Depressaria sabulella, D. argillacea, D. arnicella, D. klamathiana, D. posticella, D. nubiferella, D. parilella and D. umbraticostella; Menestia rubescens ; Glyphipteryx regalis, G. californiæ, G. bifasciata, G. unifasciata and G. quinqueferella, and Heliodines extraneella.

At the last meeting of the Entom. Soc. of Ontario, Mr. J. M. Denton reported that he had seen near Delaware, Co. Middlesex, Ont., a ten-acre pasture field almost destroyed'by the larvæ of this beetle, and he exhibited some specimens he had brought.
