Hagen.] 154 [December 27, 



the discal spot is nearly wanting. I will speak later about 

 the occasional appearance of a sub-marginal series more or 

 less incomplete of ferrugineous patches, and of one at the costa. 

 A few males have along the veins on the upperside of the prima- 

 ries black scales, giving to them a faintly striped appearance. 



The cut of the primaries is very variable ; generally the external 

 margin is oblique ; in many specimens it is somewhat concave, 

 by which the costal angle appears to be more protracted and 

 more pointed ; 17 specimens have the external margin more or 

 less convex and the angle rounded, which in a few specimens is 

 exaggerated. The hind angle of the secondaries is in one-third 

 of the specimens more strongly produced and angular ; in some 

 exaggerated cases this angle reaches 100°. The collar of some 

 specimens is pink, the other ones show all intermediate shades 

 to yellow. 



The size of the males varies in expansion of the wings from 60 

 to 43 millim. ; the average size is about 55 millim. ; five specimens 

 (dwarfs) are 46 to 43 millim., one of them was caught copulated 

 with a large female. 



Female. 



I have before me 46 females from Oregon and Washington 

 Territory, six of them caught in copula. Only two are white, 

 five more . whitish than yellow, five pale yellow, the other ones 

 lemon-yellow as the males. The primaries have a broad incom- 

 plete marginal band of black scales, which mostly does not reach 

 the edge ; it is expanded in a larger patch near the costa, and 

 reaches the hind angle in some specimens. The submarginal 

 band is followed in half of the specimens by a similar but nar- 

 rower internal band, which reaches or not the hind angle. The 

 submarginal band in one-third of the specimens has prolongations 

 along the veins to reach the inner band, and so to form more 

 or less well enclosed yellow (in one specimen white) spots. In 

 some specimens such prolongations are sent out, where no inner 

 band exists. The secondaries in eight specimens have a faint 

 marginal band of black scales, reaching the outer angle. The 

 wings of two specimens, one of them white, have no marks at all. 

 The discal spot of the primaries is similar to that of the males ;
