THE CANADIAN ENTOMOLOGIST. 239 



angular, superposed, brown-edged spots form part of the subterminal band 

 opposite the cell. The hind wings are pinkish fuscous ; both wings have 

 the short fringes shaded with orange. Almost all the Hepialin<z are thinly 

 scaled, sub-transparent, and the peculiar fact that the secondaries are also 

 1 2-veined render them anomalous among Moths. I notice that the Rev. 

 Mr. Cramer records the fact that he captured some twenty specimens of 

 the " Graceful Ghost," Hepialus gracilis Grote (the tautology of the 

 English name is better than its equivalence), sitting against the trunks of 

 trees in a cemetery (appropriate spot !) at St. Johns, New Brunswick. I 

 wonder he did not run away from them, with their ill-omened name, con- 

 ferred, I believe, from the ghostly appearance of the European Hepialus 

 Htimtdi when flying, the male of this species being silvery white above 

 and brownish gray beneath, and, in its vacillating flight, exposing now the 

 white and then the dark surface, presents an uncanny appearance in the 

 dusk of evening. A large species, Hepialus argenteomaculatus of Dr. 

 Harris, inhabits the Catskill Mountains, as also various localities in the 

 Eastern States. Dr. Harris originally in his Report describes this species, 

 which has dusky fuscous bands and is of a dull obscure tint, as compared 

 with a second larger silver-spotted species, having a salmon pink tinge 

 and figured by me in the Proceedings of the Philadelphia Entomological 

 Society many years since under the name of Hepialus quadriguttatus. 

 The silvery spots are smaller as compared with Dr. Harris' species ; but, 

 strange to say, in Agassiz' " Lake Superior," now a rare book, Harris 

 figures my larger species, which inhabits the Lake Superior Region and 

 Canada, as identical with his argenteotnaculaUis. I have also a suspicion 

 that my quadriguttatus has been re-named by Mr. Strecker, but I am not 

 certain of this synonym as I am of so many others which might have been 

 avoided by only a little more care as to what has been published. If 

 students would only study our own periodical literature covering the last 

 twenty years or so before putting pen to paper ! I know of so many 

 instances where this obvious duty has been neglected. And then if they 

 would always have surely the right name of the species they discuss. I 

 have known a great deal of argument wasted on a wrong determination. 

 In concluding this somewhat discursive, but I hope not on this account 

 less readable paper, I cannot but pay my tribute to the Canadian Ento- 

 mologist and its contributors for important contributions to the develop- 

 ment of our knowledge. Speaking with the experience of more than a
