where, whitish. Below, the sub-marginal spots are obsolete upon the 

 fore wings, and nearly so upon the secondaries ; but one silver discoidal 

 spot upon the latter, broadly encircled with ferruginous. 



A female (L) to be described hereafter, was taken at the same time, 

 in coitu. 



Underneath there are variations in the size and number of the dis- 

 coidal spots, and of the containing irises, and in the complete presence 

 or incomplete nullity of the sub-marginal ferruginous spots, varying 

 also in size. 



Specimen E. mentioned above, has the discal spot of the primaries 

 pupilled with white, which is not. however, peculiar, though I have seen 

 none containing so large a spot ; and the under side of the secondaries 

 thickly covered with greenish black scales. Two silver discoidal spots. 

 very large and prominent; the sub-marginal spots not very distinct, but 

 more so upon the primaries. 



In the color of the cilije there exists considerable variation, ranging 

 from roseate to yellowish-white ; the first being more especially marked 

 at the extremities — apical and anal. 



There is ever, but little change in the yellow color of the male, but in 

 the female we find all shades from a soiled white to an intense yellow. 



The black margin of the female, in itself, does not vary so much as 

 in the male, as its width is generally about the same, but much more 

 so in regard to the contained spots. We find these of all sizes, from a 

 mere atom to as large as a pea; all shapes, quadrate, sagittate, and 

 ovate; and numbering from three to seven. Sometimes they are con- 

 fluent, forming larger introduced spaces, and sometimes widely sepa- 

 rated. There is generally a transverse row of 3 — 5 near the apex, and 

 two in the lower part of the border, one of which, and sometimes both 

 are obsolete. The marginal band never extends inwardly upon tin- 

 inner margin as far as in the male, and in a specimen from Brazil (?) is 

 cut off, just below the first median nervule. 



It is much more triangular at the apex, and in consequence extends 

 much farther upon the costa, which together with the base, is always 

 powdered with black atoms, generally densely. 



The discoidal points are generally larger than in the male, and some- 

 times nearly round, though more usually ovate. 



Secondaries commonly have the extremities of the apical nervules 

 lined with black; the black border, though wider, is not usually so 

 long as in the male, and generally contains in its upper part, two or 

 three spots of the ground color, usually more or less imperfect, and 

 sometimes obsolete. I have a specimen (S) from Mass., in which this
