A few Notes on the Butterflies of Saskatchewan 

 (Assiniboia). 



By A. J. Croker, with remarks on the species exhibited by 

 Hy. J. Turner, F.E.S. Read April 12th, 1906. 



Last year I was three months at Miniota, a lovely place on the 

 banks of the Assiniboia River. Here I took a nice series of 

 Euvanessa antiopa, including one splendid variety, in which the 

 two yellow dashes on the costal margin are increased in size and 

 united into one great smudge of yellow, while at the same time the 

 yellow border is half as broad again as in the type. [This form 

 seems to be that named by Heydenreich as ab. hygicea, although in 

 the diagnosis no mention is made of the costal blotches, but only of 

 the extension of the outer marginal band. Dyar includes this 

 form in his "Cat. N. Am. Lep."] I had very little time for 

 collecting, but took a specimen of Pontia (Pleri's) protodice and 

 one of P. napi. The latter was a surprise. It made me think of the 

 old times at Ranmore Common and Box Hill. The large fritillary 

 I sent you is Argynnis lais, and the small one with purple underside 

 is Brcnthis bellona. This latter is a fairly common species here. It 

 is double-brooded, appearing in June and again in August. [There 

 appears to be very little difference between the two broods, at least 

 as exhibited in those from Assiniboia. It is one of the commonest 

 species over the whole of the northern parts of North America.] 

 With regard to the Clouded Sulphurs I can help you a bit, 

 I think. First of all the genus is Eurymus, according to the 

 "U. S. Bulletin," 1902, although Holland still lists them as 

 Colias in 1903. E. eury theme is the orange-flushed and 

 E. eriphyle the yellow. The yellow form appears first and then 

 the orange, but strange to say they both appear in rotation again 

 — that is to say, there are two broods of each form. Then, again, I 

 have taken two pairs of another yellow species which I take to be 

 E. philodice. This year, if all be well, I will pay especial attention to 

 the group as to dates, etc., and write you further. I have some very 

 nice forms, one yellow female without any markings, and one with 

 exceptionally broad bands. [These species were exhibited at the 

 Society's meeting last year, and a summary of what is known of 

 their extremely complex life-history was read to the Society, and is 

 printed in the "Annual Abstract of Proceedings" for 1905.] The 

 Erebia sent you is E. epipsodea, and has a range from North Mexico, 

 at a high elevation, to Alaska. I have taken two examples of 

 E. discoidalis, a species which only occurs in the far north. [Dyar
