showing very little if any variation. Skinner sinks chippciva as 

 a synonym for G. palacno Linn. , but with a suite of nearly forty 

 specimens of C. palacno before me from various localities in 

 Europe and Asia, I can at a glance separate the specimens 

 from Alaska. On the upper side the dark marginal band of 

 the males is much narrower, and the specimens are smaller. 

 The females on this side are almost without any dark margin, 

 resembling in this the females of C. scuddcri. On the under 

 side of the wings they are quite different from C. palacno, one 

 marked feature being the light-colored ray which runs from 

 the discal spot of the secondaries toward the base, through the 

 darker grayish green ground color of the wings. If C. chipper 'a 

 Edw. is not a good species, it is at all events a very strongly 

 marked varietal form, which, when known, is not easily mis- 

 taken.

The collection contains numerous examples, mostly in bad 

 condition, of the small Alaskan form in which there is a con- 

 siderable range of variation in size and in color. One female 

 is decidely dark, showing a tendency toward melanism. Some 

 of the males are abnormally light, and three examples have the 

 ground-color of the wings whitish, almost as light as in P. 

 curvnicdon. The specimens, twenty-one in number, were 

 mostly taken at White Horse, N. \V. Territory and Kagle 

 City, Alaska.
