FURTHER NOTES ON ALBERTA LEPIDOPTERA. 



BY F. H. WOLLEY DQD, MILLARVILLE, ALBERTA. 



(The numbers refer to my list previously published in this magazine.) 

 1. Danais archippus, Fabr. — Both Mr. Willing and Mr. Gregson 

 inform me that there can be no doubt that the species breeds here. It is 

 not likely, however, that it survives the winter in any stage. 



[3a. Argytmis leto, Behr. — I have had a few specimens sent me as 

 this species from Utah and Idaho. The males differ from eastern cybele 

 mainly in being less heavily marked with black, especially in the outer 

 row of round spots in the interspaces, with a distinct tendency towards 

 the gradual obliteration of all markings near the apex, and in having 

 smaller metallic spots beneath. My only female of these is pale straw 

 instead of pale red as in typical cybele^ and both sexes agree well with 

 Holland's figures. Some Calgary specimens taken since my last list was 

 published closely approximate these, though I cannot see that they are 

 superficially separable from the local cybele^ as they appear to grade 

 through. My only local female of either, taken in cop. with one of the 

 most intermediate males, is considerably paler in colour than eastern 

 females, but except in being much smaller, otherwise approximate them 

 rather than my Idaho specimens. In short, what I have listed as cybele 

 seems strictly referable to neither so-called species.] 



4. A. cypris, Edw. — The species is, without much doubt, identical 

 with cypris S sent me from Denver, Colo., which, however, is somewhat 

 richer in colour. The resemblance of the local form to the paler forms of 

 lais is very close, and confusion is easy without a good knowledge of 

 both. Though nearly all Calgary specimens that I have seen are a little 

 larger, a series I took last summer on the Gleichen prairie, as well as some 

 submitted to me by Mr. Crocker from Redvers, Sask., are decidedly 

 smaller than Calgary lais. The apices are more acute, and outer margin 

 very slightly concave instead of straight or slightly convex as in lais. The 

 veins of primaries are much less prominently black marked. Another 

 difference is in the greater length and thickness in cypris of the tuft of 

 hairs on the subcostal vein of secondaries. Also, this tuft, as well as the 

 rest of the hairs near the inner margin, show, in certain lights, a very 

 distinct violaceous reflection, quite characteristic of the species^ and not 

 seen in lais. These remarks apply to the male. I have only one 

 undoubted female, taken in cop. Other females scarcely differ, but
