[Eeceived September 7, 1880.] (Plates LIV.-LV.) Although the series of Phytophaga collected by Mr. Buckley during his last travels in Ecuador is not very numerous and is devoid of the smaller species of Halticidee and Galerucidce, it nevertheless contains a good many new and interesting species, of which a great part are not only inhabitants of Ecuador, but have also been found either in Peru or the Amazonian region.
