THE CANADIAN ENTOMOLOGIST. 85 



botanists 1) on his return from the summer's collecting in California and 

 Nevada, 1878, went to Reading, and at once identified Arge z.^ Monti- 

 vaga, many examples of which he had taken at Tallac, Nevada. The de- 

 scription supports Mr. Mead's testimony. Erinna was unknown till five 

 years after Arge was described, when the first examples were brought in 

 from Washington Territory. Neither it nor Eurynome are Californian. 

 In Butt. N. A., Vol. II., Eurynome is figured and its egg: in Vol. III., 

 Egleis and its egg. Apart from the sufficient distinctness of the imagos, 

 the different form of the eggs is decisive, though doubtless Mr. Elvves 

 does not know it. There is no appreciable variation in the shape of the 

 eggs of any species of Argynnis. Mr. Scudder relies implicitly upon this 

 fact, even in the characterization of genera. If one is higher than broad, 

 with a given number of ribs, all are ; if one is broader than high, all are. 

 The egg of Eurynome is squat, as broad as high, with twenty ribs ; Egleis 

 is tall, considerably higher than broad, with eighteen ribs. I may say 

 here that nowhere in the paper do I find the least reference to the plates 

 in Butt. N. A., except on page 574. When talking oi Bischoffii 2a-\6. Opis, 

 I read : " In Edwards' figures I can see no specific characters." In the 

 list most of the plates are referred to, but in the text no one would sup- 

 pose that any of these species had been figured, or that such figures as 

 are given were of the least use in determining species. The author pre- 

 fers to trust to his " authentically named " specimens. 



On p. 536, he says he has not Inornata in his collection, and indirectly 

 that he never saw it, but he " cannot recognize it as a species." 

 Nothing further is said of it, but in the list it is put under Callippe, 

 " ? var. vel trans, ad Edwardsii, vel ad Zerene, Inornata.'' Edwardsii 

 in no one character resembles Zerene, and is Coloradan, while Inornata 

 is found only in California. The plate shows it to be one of the 

 most distinct species of the fauna. The male is as red as Adiante. 

 Callippe has no red about it, but is dark and melanic. So that here 

 Inornata is put down as related to three wholly unrelated species, under 

 one of them, and on its way, " trans." to the other two ! 



A. Hippolyta, which is kept up " (a favorite and charming phrase ! ) 

 " by its author as a species, and seems to be something intermediate 

 between Hesperis and some form oi Zerejie" (all loads lead to Zerene ! ) 

 " Its locality would indicate that it may be nearer to them than to
