70 ENTOMOLOGICAL NOTES. 



when he described Pembina that it w!ls allied to Pheres, (in which he was not so very far out of the way,) lie has since changed his idea, 

 for between ihe four species (Behrii, &c.,) and Plieres he has placed lliirteen others. 



Mr. Kdwards, who of course kiiows his own species, has received also of ihese Anticosli examples, and the shortest plan to determine 

 if tliey are Lyciiena Pembina, Kdwd. or Ulaucopsyche Couperi GKOTK, is for liini to say which, at his early ctmvenience, and much 

 oblige a great many of us uninitiated, for as a matter of course we cannot expect Mr. Grote to do so, liis lime being so much taken up in 

 attacking the life-long labours of Jlr. Walker, of the British museum, that he really is unable to give the renuisiie attention to other 

 matters, thus he is, how unfortunate, compelled to suffer, or as his own beautiful and toncliing language expresses it, " I elect to suffer 

 through an injustice rather than countenance an .apparent wrong." !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 



LIMENITIS PKOSERPINA, Edwards, is doubtless a form of L. Artlieiuis bearing the same relationship to that species as does the 

 aberrant L. Tremnla;* to L. Populif in Europe. 



PIEKIS BECKERII,! Edwards, from Nevada, is certainly identical with P. Chloridice,^ found in Turkey, Sarepta, Siberia, &c. ; 

 several Lepidoiiterists, as well as m^'self, have compared the two, and excepting that the Nevada examples are a little larger, cannot 

 detect any differences that might warrant the retaining of the latter as a distinct species. 



In what Mr. Grote's new C.itocala Meskei || differs from Unijuga, Walker, I am at a loss to perceive ; Mr. Meske had the goodness 

 to send me Grote's type for examination, but I cannot with my be-;t will pronounce it anything else than Unijuga ; 1 have since sent to 

 Mr. Meske three examples fj' and 9 which he pronounces the same species as the one which Grote described as Meskei, and so they 

 are, but nevertheless they are at the same time Unijuga too, and as we are supposed to go in nomenclature by the law of priority, it will 

 still have to stand as Unijuga, although Mr. Grote doubtless imagines, after the manner of " the Ingenious Gentleman Don Quixote," 

 that he has acheived a glorious victory over Mr. Walker and has thereby acquired the right of annihilating that author's species as 

 spoils of war. 



N. B, — If C'atocala Arizonia;, described in same paper with C. Meskei, does not turn out to be one or the other of Dr. Von Belu-'a 

 species, others than my.self will be much surprised. 



I trust that, though the species figured in this No. are not conspicuous or showy, it still may not be devoid of interest. The 

 next No. (IXj will be devoted to N. Am. Catocalse.
