2 While Mr. Walker, in the British Museum Lists, refers Canadian specimens of A. Langtonii 

 to A. 8-maculata, I think it probable that Mr. Couper describes the latter species as the male 

 of A. Langtonii. This supposition, however, becomes unlikely when we see that Mr. Couper 

 quotes my letter describing the male A. 8-maculata, with which he is unacquainted, in the same 

 Paper. If Mr. Couper is correct, we have to do with a species in which, while the female has 

 but a single spot on the hind wings, the male has two spots, like A. 8-maculata. But I think I 

 have both sexes of A. Langtonii agreeing with Mr. Couper's original illustration. A mistake is 

 the more likely to have happened, since Mr. Couper compares his species, in the first instance, 

 with A. MacCullochii, Kirby, instead of with A. 8-niaculata. Kirby gives the color of the 

 spots on both wings in his species as white. Both Kirby's very good figure and a specimen 

 before me from Owen's Lake, Nevada, show a sulphur tinge on both wings, though more decid- 

 edly on the primaries. A. Langtonii 8 has also the spots concolorous on either wing, and 

 it is probably only in A. 8-maculata that the spots on the primaries are sulphur yellow and on 

 the hind wings white. Now that we have also a Californian spei'ies described with all the spots 

 white, our remark as to the correspondence in the color of the spots between the species of 

 Alypia inhabiting the same Fauual District, becomes incorrect.
