Male. Upper side black, secondaries only having a slight bluish 

 (occasionally greenish) tinge ', hind margins of secondaries bordered 

 by a double row of blue (or green) crescents; the submargiual row is 

 continued on primaries, but is indistinct, almost obsolete; beyond the 

 ci'escents, on secondaries, is a row of russet spots surmounted by blue 

 (or green) scales, which are more or less conspicuous ; in some speci- 

 mens the russet spots ai'e distinct across the whole wing, in others two 

 or three only are seen, and in others they are altogether wanting; the 

 blue scales or spots make a circular band across secondaries, and are 

 continued across primaries with more or less distinctness (often becom- 

 ing whitish) to the costa, and correspond with the white band of under 

 surface; the contour of this band above is like that of Arthemis, and 

 it terminates on the costa in a white streak ; there is also a white sub- 

 apical s|)ot divided into two or three by the nervules, emarginations white. 



Under side brown, varying in shade from blackish to russet, and in 

 this respect and in markings remarkably like Arthemis, except that 

 the white baud of the latter is here always slight and sometimes partly 

 wanting; both wings have a double row of blue (or green) cresceuts. 

 preceded by a row of rounded russet spots, large on secondaries, and 

 on these, edged above and below with black ; the spot at inner angle 

 of primaries is wanting; above the russet spots is ^ curved whitish 

 band or streak, common to both wings, sometimes half the width of the 

 band of Arthcmla, but sometimes indicated by a few scales only above 

 the russet spots ; the subapical spot and costal streak of upper side re- 

 peated conspicuously; base of wings marked by russet spots edged with 

 black ; between these are metallic blue (or green) patches as in Arthemis. 



Body below white ; fore legs white, palpi white, edged with black ; 

 antennae and club black, tipped witli ferrugiiidus. 



Redescribed from six males taken in Stoney Clove, Catskills, on the 

 2d and 4th of July, 18G7. The species was abundant, and all taken 

 were fresh fioni chrysalis. The female I have not yet seen. 



Although the color of upper side of Proserpina is much like that of 

 Ursula, in all other respects it is more closely allied to Arthemis, curi- 

 ously imitating that species in the color and niarkinus of the under side.
