1928] Notes on Some Butterflies from New England 227 
numerous at the end of the season, and has been noticed as late 
as November 11. 
Eurymus eurytheme form keewaydin (Edwards) 
Of the three males from Ipswich, Mass., taken on August 
25, 1925 (Psyche, vol. 32, No. 6, December 1925, p. 297), one 
approaches closely the light form keewaydin to which, I believe, 
it should be referred. A second is intermediate, and the third, 
which is the largest, is of the form amphidusa . All three in life 
had slight violet reflections. 
About Washington the form keeivaydin is most common in 
late summer. 
Bryas aphrodite cypris (Edwards) 
Seven males and two females referable to this form were 
taken at Essex, Mass., all after the middle of July, 1925. They 
are at once distinguishable from the common form of aphrodite 
occurring in the region by the longer and narrower fore wings of 
which the outer border is distinctly concave, and by the less 
rounded and shorter hind wings. The ground color of the upper 
surface of the wings is light and almost uniform, and the black 
markings are reduced. 
The two females have the wings more nearly of the normal 
type than the males. In both the black bar between veins Ml 
and M2 is extended inward so as to form a conspicuous black 
patch. 
Careful comparison with a series of cypris from Colorado 
removes all doubt regarding the identity of these specimens. 
Probably they do not represent an isolated colony of this 
western form, but instead should be interpreted as examples of a 
well characterized variant (a light long-winged “dry” form) which 
in portions of the west becomes the sole representative of the 
species. 
Yet the occurrence in the same year in the same region of 
Eurymus eury theme in the northern “dry” ( eriphyle ), interme- 
diate ( keewaydin ) and “wet” ( amphidusa ) forms should be borne 
in mind.
