Two papers in the last (April) number of the Canadian Entomologist are of great interest to me, and both on the same general topic applied to very different species. Mr. Lyman makes an earnest effort to save Mr. Walker's name Spilosoma congrua, and gives all the facts relating to the name, its publication and subsequent history; upon which facts Mr. Lyman and Sir George Hampson reach opposite conclusions. I have no liking for Mr. Walker's species, but I think I would side with Mr. Lyman in this case, because, with all the examples before them, Messrs. Grote and Robinson separated out a good species with which a specimen of another, previously knolwn, was erroneously associated. By removing one example, a good species remained, to which the name given by the author could be correctly applied.
