ON SOME NORTH AMERICAN SPECIES OF CHIONOBAS. 



BY DR. HERMAN STRECKER, READING, PA. 



Last December Mr. H. J. Elwes gave a revision of the genus Chionobas 

 in Trans. Ent. Soc, London, to which Mr. W. H. Edwards, in the March 

 number of the Can. Ent., gives " notes," or rather exceptions, in which he 

 still contends that Gigas, Calif ornica and Iduna are three distinct species, 

 but now allows Nevadensis, which he formerly considered also to be dis- 

 tinct, to be a synonym of one of these, but does not know of which. 

 Elwes has placed these four as one species, just as they are in the 

 " Synonymical Catalogue " issued by me in 1878, nor can I understand 

 how anyone can imagine there is more than one species under the four 

 names ; there is absolutely no point by which any of the examples can be 

 separated, whether they come from California, Washington, Oregon or 

 elsewhere ; were they to be mixed indiscriminately, without locality labels, 

 no one could say from whence came this or that example, or which was 

 this or that so-called species. 



With Subhyalina Elwes has followed our Syn. Cat. in the same way, 

 with the single exception, an important one, that he has given the name 

 Subhyalina priority over Crambis, which it reglly has by right of publi- 

 cation, if the two names belong to the same insect, but the doubt sur- 

 rounding the former name, which I believe belongs to an Erebia, 

 influenced me in placing Freyer's name first. The description of Hip- 

 parchia Subhyalina in appendix to Ross's 2nd Voyage, evidently fits 

 Erebia Fasciata^ or a variety of it, and, as Edwards suggests, the example 

 in Oberthiir's collection submitted to Elwes may not be the type, as 

 certainly, if it is the same species as Bean took in N. W. Territory, it in 

 no wise agrees with Curtis's description. 



Ch. Alberta, which Edwards insists is Varufia, is a smaller form of 

 Chryxus, of which I have good examples, $ $ , received from Morrison 

 a number of years since, who took them in Idaho ; Elwes's types came 

 from Calgary ; he says in the collection of a Mr. WoUey-Dod, from whom 

 he obtained them, were also examples of Varuna. At the same time I 

 received from Morrison Alberta (? V 3 he also sent Varuna, $ $ , taken 

 at same locality. There is no difficulty in distinguishing these two, as 

 Varuna is a variety or form of Uhleri, whilst Alberta occupies the same 

 position towards Chryxus. Varuna I also have from Bean, in N. W. Ty., 

 and from Morrison, from Arizona. I have Uhleri, from Colorado, not to 

 be distinguished from Varuna, from Idaho and Arizona. The female of
