species. I have treated sufficiently of this matter in Part 12, Vol. III., 

 B. N. A. The case is parallel to that of Chryxus and Ivctllda, allowed 

 by the author to be two species. But, if Varuna cannot be separated 

 from Uhleri^ how can the author be sure that the Kananaskis examples 

 at 4,000 feet (5,000 + of Colorado), were not Ulileri 2 It is altogether 

 probable they were. On p. 467, a new species called Albei-ta is described, 

 from Calgary. It is a curious thing that this Alberta is put between JP.II0 

 and Chryxus, though it is said to "bear the greatest superficial resemblance 

 to Taygete." Now, on comparing the description of Alberta with the plate 

 and description of Varuna, in B. N. A , Vol III., these two cannot be dis- 

 tinguished from each other. Mr. Fletcher tells me he sent me an example 

 of this Alberta a year ago, and I returned it labelled Varuna. Really 

 this is too too ! Why then all this jumble about three other non-allied 

 species ? 



Mr. Elwes does not think that Semidea is found in Labrador ; at least 

 he has seen no specimens from that quarter. Here I am pleased to say 

 that I agree with him, as I have never seen a Semidea from Labrador. 

 But he has no doubt that a specimen in Mr. Lyman's collection from 

 Hudson's Strait is Semidea. Similarly I have a single example, a female, 

 taken at Fort Chimo, Hudson's Strait, that I consider to be Semidea. 

 The species will be fully illustrated in Pt. 15, B. N. A., Vol. 3, soon to 

 issue. What Moschler distributed as Semidea, from Labrador, was ^no, 

 Boisd., and Aino is the species taken on the peaks of Colorado. Assim- 

 ilis is a variety of ^no, taken in both localities. It is without a band on 

 under hind wings, or almost none. I have treated fully of these forms in 

 Part 14. Mr. Elwes continues, p. 473: "All authors who have yet 

 examined specimens of the form occurring in Colorado seem to agree in 

 identifying them with the typical White Mountains Semidea, but, on com- 

 paring a series of five pairs from each locality, I can certainly pick out the 

 Colorado specimens by the following. characters," etc., etc. ; closing thus : 

 " I certainly think there is good ground for looking on it as an incipient 

 species." It is identical with Labrador ^'Eno beyond a doubt. 



This brings us to Subhyalina, Curtis, p. 475 : — " I have had more 

 difficulty in dealing with the synonymy of this species than any other, 

 but, after having compared the unique type of Subhylina, Curtis, in 

 Guenee's, collection, kindly lent me by Mr. Oberthur, the figure oi Cram- 

 bis, given by .Freyer, the type of Assimilis, in the British Museum, and 

 several other specimens in the British Museum from various parts of Arc-
