424 ENTOMOLOGICAL NEWS. [Dec. , '07 



was probably the same, or possibly a mixture of both forms, 

 and that, therefore, T. inorata, G. & R., was correctly described. 

 He, however, made several errors in his references, giving 

 the reference to his author's separate instead of to the "Trans- 

 actions" for T. inorata, and giving on the last line of that 

 species a reference to the "Transactions" where T. lorata was 

 described, and in which there was no reference to T. inorata. 

 In connection with this paper a very curious error was after- 

 wards made by him, as in Can. Ent. XIX, 179, he refers to 

 the above paper as "printed at Demopolis, Ala.," and "now 

 out of print, but is in several libraries, and was generally dis- 

 tributed." Evidently he had before him an author's separate, 

 and had quite forgotten that it was only written from Demopo- 

 lis and printed in the Canadian Entomologist. 



Scudder's reference under calanus, to Fernald's Butterflies 

 of Maine, is erroneous as to pages, which should be 78-79 in- 

 stead of 80-81. 



Evidently these distinguished authors did not sufficiently 

 heed the advice of the late Dr. Martin John Routh, the learned 

 president of Magdalene College, Oxford, "Always verify your 

 quotations." So much for the literature of the subject; let us 

 now turn to the butterflies themselves. 



Dr. Skinner began by separating his specimens by color, 

 and then concluded that they all belonged to one species. 



On that method of procedure, no other result could be ex- 

 pected, for while it is quite true that in perfectly fresh speci- 

 mens calanns is darker than edzvardsii, this difference is soon 

 lost in flight, and I have a specimen of true calanus which is 

 lighter than any specimen of edzvardsii in my collection. 



What might be called the key to these species is found in 

 the extra mesial band of the under surface, in calanus the 

 spots forming a band, as indicated by Scudder's English name, 

 "The banded hair streak," while in edzvardsii they are distinct, 

 though by no means equally so in all specimens. As butter- 

 flies are not stamped by a die like coins, they necessarily vary, 

 and in two such closely allied species as these we must natu- 

 rally expect to find some of the variations running very close 

 to each other, but I have never found a specimen which I could 

 not place.
