Daedalus Behr we think should be a form of icarioides, possibly 

 an aberrant one with transversely drawn out spots on primaries ; Behr 

 associates it with icarioides which he had apparently identified cor- 

 rectly. 



Mintha Edw. is a doubtful form from Nevada, possibly a well 

 marked ardea; we have not been able to find the type either in Pitts- 

 burg or New York. 



Helios Edw. is also doubtful and the types are seemingly lost. 



Ardea Edw. 



The species was described from the neighborhood of Virginia 

 City, Nevada, and the $ type is in the Hy. Edwards' Collection in 

 New York; it is a rather small specimen with greatly reduced macu- 

 lation on the underside of both wings, the ground color being a pecu- 

 liar light-gray ; we have a series from Pyramid Lake, Nevada, the $ 's 

 of which agree closely with the type in ground color of underside, but 

 have the spots of the primaries better developed. We think ardea 

 will prove to be a race of icarioides from the Great Basin region, with 

 paler violet-blue color and very slight dark marginal border; on the 

 underside the dark spots tend to become obsolete and appear as white 

 spots with faint dark centers ; throughout Utah and in Colorado west 

 of the divide we meet with a very similar form showing the same ten- 

 dency to reduction of spots, but with slightly more pronounced black 

 marginal border; this form has been variously called evins or pheres, 

 but we imagine should be rather referred to ardea. We figure the 

 underside of a Nevada $ . 



Lycea Edw. 



This is the race from Colorado west of the divide and is typical 

 in the canyons around Denver ; rapahoe Reakirt is the 9 of this form, 

 a 9 with rather more blue than usual being mistaken by Reakirt for 

 the $. 



Pembina Edw. 



The species was described from Lake Winnipeg; we have no ma- 

 terial from this locality, but specimens from Calgary and Yellowstone 

 Park seem to fit in with the description well ; the types seem to be 

 lost. It is a small race with little blue on 9 's and tendency to darker 

 color, broader borders and distinct discal dash in $ ; the underside is 

 rather brownish with often a reduction of the black spots to mere dots 

 and a corresponding increase of white encircling color as in ardea.
