In this series of 34 specimens 16 have the disk of the wings

 observed in the field the yellow-winged form seemed to be 

 somewhat more numerous than the orange- and pink-winged 

 forms. The wings of the yellow-winged form are of a rich 

 hue, slightly tinged with orange, and quite different in color 

 from the lemon-yellow wings of some Massachusetts speci- 

 mens in the collection of the University Museum.
