median vein; it begins behind or at the hinder edge of the costal band and is either straight or 

 incurved in its course to the median vein, and thence to the inner edge of the wing is either nearly 

 straight or slightly sinuous; it is broad, white, edged with pink and beyond narrowly bordered 

 with black. The extradiscal line is nearly straight or slightly sinuous, ending in the two black 

 spots on the costa, the spot on the costal edge linear, the one parallel to it on the inside being 

 about twice as broad, and in one ? nearly triangular; the line tends in some specimens to be- 

 come obsolete toward the apex and near the two black costal spots; the band is dark brown, 

 shaded externally rather irregularly so as to be scalloped on the outer edge with pale gray lilac, 

 or pinkish white. 



On the hind wings this line is curved and is twice as broad as on the fore wings, and especially 

 the inner dark brown portion is broadest toward the middle and costal region. From the inner 

 of the two black spots a broad grayish lilac shade or dash passes nearly out to the apex. At 

 the outer end of the other or linear spot is a short mark of the same hue. 



Discal spots rounded, elliptical, varying much in size, those of the fore wingwith the transverse 

 diameter greater than the longitudinal, the anterior end or side always reaching to vein II, but 

 the posterior never touching median, and in some examples the spot only extends half way across 

 the discal cell. In a well-developed discal spot or ocellus the vitreous or transparent center is 

 about half the width (in one ? much wider) of the entire ocellus, the discal vein dividing it into 

 two unequal portions, of which the inner is the smaller. This vitreous center is surrounded 

 by a broad ochre-yellow ring, wider on the outer than inner side, sometimes nearly twice 

 as much so; it is edged with a narrow linear black ring, and externally on the outside is a narrow 

 linear whitish-blue semicircle, not extending beyond either end of the discal vein. 



Hind wings entire. Apex subacute, the outer edge bent at the end of the median vein. 

 Extradiscal line curved outward, a broad, diffuse dusky band, shaded externally with grayish 

 lilac, and beyond this line the wing is ochreous as on the fore wings. Discal spot very large, 

 and the ocellus itself, corresponding to that of the fore wings, is a little larger than in the anterior 

 wings and of the same general shape, but produced shaqily at each end (antero-posterior) ; the 

 yellow ring is decidedly thicker on the outside and is edged with a distinct fine linear black line. 

 It varies in size, either reaching the origin of the first median vem or ending quite a distance 

 from it. The ocellus proper is surrounded by a large oblong oval black shade, not only filling 

 the space or cell, but spreading over a little way into the cells on either side of the veins II and 

 median. It is bounded on the inner end by a red and white line, being a portion of the basal 

 line, and situated about half way between the base of the wings and the discal vein. On the 

 outside of the ocellus is a faint linear pale blue semicircle, while on the other side of the ocellus 

 or yellow ring about half and sometimes nearly two-thirds of the black patch is colored pale 

 blue, the blue scales varying in intensity and in some examples almost wanting. 



Underside of the wings. The basal band of fore wings dark, the wing within paler and more 

 grizzled than the rest of the wing. On the hind wings this portion sends two narrow streaks, 

 one to each side of the ocellus, then spreading out trigonately. Middle of wing darker, nut-brown, 

 the outer edge of this shade vaguely scalloped, and the inner edge also in some examples; this 

 shade or broad band is succeeded by a lighter shade, either pale ash or dusky lilac, the outer 

 edge darker, corresponding to the extradiscal line above. The edge of the wing is either pale 

 ochreous or ochreous brown. The two apical spots are disconnected from the extradiscal band. 

 In the median shade a dull reddish brown, broad, diffuse band crosses the wing, inclosing the 

 discal spot when it is small, and when the spot is large, being interrupted by it. 

 There is no essential or striking difference between the sexes. 



Expanse of fore wing, S 116-127 mm.; 2 125 mm. 



Length of wing, a* 55-58 mm. ; 9 66 mm. 



Ocellus of fore wings: Length, 2^-7 mm.; width, 2-7 mm. 



Ocellus of hind wings, not including the black and blue patch, 4-7£; black patch, 

 10 by 6 to 16 by 12 mm. 

 In a quite pale ? the ocellus of the fore wmgs is unusually large and round, and the vitreous 

 center large and round.
