In the Hopeian Collection is preserved the monstrous specimen of this pretty species from Sierra Leone 
here figured. The ordinary male character of the specimen is shewn on the left side of figure 11, exhibiting a 
large red spot on the broad apical margin of the fore wing, the dise of which is entirely white, and the white 
hind wings with black marginal spots, to which two small somewhat oval ones are attached, extending into the 
dise of the wing. The ordinary character of the upper side of the female is shewn in figure 12, shewing the large 
broad apical spot, and an oblong one on the inner margin of the fore wings (which are dilated below the middle 
of the apical margin), and the hind wings marked with a dark subcentral fascia as well as the marginal spots. In 
the specimen before us the left side of the insect is entirely male, and the wings on the right side are female 
in form, and the hind one is also female in markings; but the fore wing has the broad apical dark margin 
marked with an irregular series of red spots, thus partaking of the character of the male.

Prats XXXV, Fie. 2. 
The ordinary character of this very common butterfly is the entirely sulphur-yellow colour of the wings of 
the male, and the greenish-white colour of those of the female. I have seen several monsters of this species in 
which one or more of the wings exhibit a combination of the colours of the two sexes. 
In the specimen here figured (fig. 2) from the Collection of Herr Staudinger, of Dresden, the fore wing on 
the right side is female, with the anterior and posterior margins masculine, and with two orange dots on the 
dise beyond the cell; the right hind wing is entirely masculine ; the left fore wing has the anterior half mascu- 
line, with two spots at the end of the discoidal cell, and a spot on the apical margin as in the female; the 
posterior half is female, with a bipartite orange spot on the dise beyond the cell; the left hind wing has the 
costal half female, and the inner half male, with a pale spot near the anal angle. 
Plate XXXV, fig. 10, exhibits the right fore wing of a specimen of the same species in the Collection of 
Mr. F. Bond, which has the two wings on the left side, and the hind wing on the right side feminine ; but this 
right hand fore wing is confusedly divided (for the most part longitudinally) between the male and female 
colours. The specimen was taken near London, 
Mr. F. Bond possesses another specimen which is entirely masculine except the costal region of the fore 
wing on the left side, which is female, with a small narrow yellow dash in the middle of the costal edge. 
Mr. F. Bond has also recently obtained from the Collection of Mr. Edmunds, of Worcester, two specimens with 
irregular markings of the two sexes, but with the peculiarity that the markings are exactly similar on the two 
sides, the under surface of the wings, moreover, shewing the same markings as on the upper surface. In one 
of these specimens the basal half of all the wings is masculine, with slender white dashes on the chief veins, 
whilst the apical half is feminine, the body being also female. In the other specimen the fore wings have an 
oval spot of the female colour near the apex, an elongated dash between the second and third branches of the 
median vein, and the inner margin with a broad border of the female colour. In the hind wings the discoidal 
cell is of the female colour, from which three broad stripes of the same colour extend to the outer margin of the 
wing, each occupying the alternate space between the longitudinal veins of the hind wing beyond the cell. 
From the regularity of the markings of these two specimens, and their identity on the two sides, one is 
almost tempted to fancy the male colour may have been discharged in the pale parts by art. 
The Royal Museum of Berlin also possesses two interesting specimens of the same species. In one the left 
fore wing is masculine, and the two hind wings are feminine, except that the left-hand hind wing has a central 
narrow stripe of male colour running from the base of the wing, over the ordinary discoidal orange spot, and 
extending to the outer margin of the wing; the right fore wing is female, except that the costa for two-thirds 
of its length from the base, a narrow longitudinal streak running through the discoidal cell from the base to 
below the apex of the wing, and a dash parallel with the inner margin, are masculine. 
The other Berlin specimen has the right fore wing and the anterior half of the left fore wing female, the
