 Wings above, in both sexes milk-white ; in the male the anterior wings have a narrow brown pos- 

 terior border, the hinder wings are surrounded by a delicate black striga, interior to which is an 

 obscure interrupted brown band, in which the large ocellate spot at the anal angle distinctly 

 shows itself; in the female the wings have a broad brown border, which in the fore wings is sim- 

 ple and more extended near the tip, in the hinder wings waving internally and bearing a series of 

 brown spots of a deeper tint towards the anal extremity ; these spots are enclosed individually by 

 two white crescents applied to each other from the opposite sides and forming a white ring, exte- 

 rior to which is a deep brown marginal streak, terminated by a grayish-brown fringe. Wings 

 underneath grayish-brown, varying in intensity of tint : anterior wings with seven, posterior wings 

 with nine, transverse white striga;, of which three are marginal, extending uniformly through both 

 pairs : the remaining striga; in the anterior wings are discoidal, regularly parallel, with a slight 

 inclination to the posterior apical angle, arranged in two pairs, the first, on the disk, short and 

 separated from the costa by three dots, disposed as the points of a triangle ; the second extending 

 nearly half across the wing, each with a dot at its contact with the costa slightly deviating from 

 the regular course. On reaching the middle of the wing these strigas are all abruptly terminated 

 at one of the longitudinal nerves, and each pair is continued by a single streak to the posterior 

 margin ; in consequence the striga; appear divided, resembling in some cases two successive 

 figures of the form of the letter Y. The posterior portions of the striga; have undefined, spreading 

 edges, and in many individuals the whole of the posterior portion of the wing is milky and 

 discoloured. Of the three marginal striga;, the interior is broadest and most prominent; reaching 

 the posterior part of the wing, its inner edge expands in a diffuse radiant border, gradually 

 mingling itself with the clouded milky surface ; the intermediate one is undulating, and com- 

 posed of a connected series of lunules directed outward; the exterior striga is continued, re- 

 gular, parallel with the margin, and exteriorly defined by a narrow black line, beyond which is 

 a grayish fringe: these marginal striga; preserve in the hinder wings the same character, until 

 they are partially interrupted in the anal region ; the surface of these wings is further marked 

 with six transverse strigae, disposed in three pairs, one near the base, a second across the disk, a 

 , third intermediate between this and the marginal ones; the basal striga; are delicate and regu- 

 larly transverse, with a slight curve at the interior margin; the discoidal pair is not continued 

 quite to the exterior margin, but has, at its commencement, a short intermediate lineola ; at the 

 interior margin.it is inflected inwards, so as to form, abruptly, an acute angle; the third pair 

 extends only half across the wing, having a short intermediate lineola at its posterior termination. 

 In both wings the ground colour assumes, in some individuals, between the transverse striga; a 

 deeper tint, so that these appear to be marked with broad, transverse, brown bands : but this is by 

 no means uniform : some of our specimens have these brown bands very distinct, in others,
