Last December Mr. H. J. Elwes gave a revision of the genus Chionobas in Trans. Ent. Soc., London, to which Mr. W. H. Edwards, in the March number of the Can. Ent., gives “notes” or rather exceptions, in which he still contends that Gigas, Californica and Iduna are three distinct species, but now allows Nevadensis, which he formerly considered also to be distinct, to be a synonym of one of these, but does not know of which Elwes has placed these four or one species, just as they are in the “Synonymical Catalogue” issued by me in 1878, nor can I understand how anyone can imagine there is more than one species under the four names; there is absolutely no point by which any of the examples can be separated, whether they come from California, Washington, Oregon or elsewhere; were they to be mixed indiscriminately, without locality labels, no one could say from whence came this or that exmaple, or which was this or that so-called species.
