The Butterflies of North America, by \V. H. Edwards. Third 



Series, Part XV. 



This part, like its immediate predecessor, is of especial interest to 

 Canadian Entomologists, as it is chiefly devoted to the illustration of 

 some of our most interesting species of butterflies, and more than main- 

 tains the very high standard of excellence to which Mr. Edwards has 

 accustomed us. The first plate is devoted to two rare species of Argy- 

 nnis from the Rocky Mountains of Alberta, the first being Astarte, for so 

 many years practically unknown, save to those having access to the type 

 in the British Museum, the locality whence it was received being even 

 in doubt. True, it had been figured as to its upper side, in Doubleday, 

 Hewitson & Westwood's great work "The Genera of Diurnal Lepidoptera," 

 but that was not sufficient to identify it, so when it was re-discoveerd by 

 Mr. Thomas E. Bean on the mountain summits near Laggan, it was very 

 naturally re-described, or rather re-named, by Mr. Edwards, as Ai-gynnis 

 Victoria. The species is quite unlike any other North American species 

 of this genus, and Mr. Bean's notes on its habits are very interesting. 

 There is a slight clerical error in the reference to the plate in Doubleday's 

 work, as it should be 23 instead of 53, as given by Mr. Edwards at the 

 head of his article. The second species treated of is A. Alberta, a most 

 distinct and interesting species belonging to the Chariclea sub-group, 

 which also was discovered by Mr. Bean on the mountains near 

 Laggan, in 1888. The sexes differ considerably in colour, and so far as 

 known the imago only appears every second season, being found in the 

 even numbered years. 



The second plate is devoted chiefly to another butterfly discovered by 

 Mr. Bean at Laggan, a species of Chionobas, which Mr. Edwards regards 

 as identical with C. Subhyalina, Curtis, described in the Appendix to 

 Ross's Narrative of his Second Voyage, the solitary type of which was 

 taken in Boothia Felix. This identification, however, not being altogether 

 satisfactory, and the species having been described by Mr. Elwes in the 

 Trans. Eat. Sdc, Loaion, as C. Beaaii, it will doubtless be known by 

 the latter name. 



In connection with this, it may be mentioned that the specimens in 

 the British Museum collection, under the name Subhyalina are different 

 from the form from Laggan, and seem to agree more closely with 

 Curtis's description. A specimen from Hudson's Straits similar to those
