posterior half of the left fore wing being masculine: the right hind wing is female, with a large yellow patch 
near the outer angle, and the left hind wing is female, with a yellow stripe extending from the discoidal spot 
to the outer margin, the outer angle of the wing, and two irregular spots between the angle and the anal edge 
of the masculine colour.

Mr. Hewitson possesses a curious specimen of this Brazilian species here figured. The ordinary character 
of the male is shewn on the left side of figure 6, and the corresponding side (that is, the right side) of the under 
surface shewn in fig. 7. The wings of the female are pale buff, slightly darker at the base, with a broad black 
apical spot in the fore wings. In this sex the outer angle of the hind wing is more prominent than in the 
male, the inner margin of the hind wing being shorter than in the male. In Mr. Hewitson’s specimen the two 
wings on the left side and the hind wing on the right side are masculine (except that the latter has a female 
coloured spot in the middle of the costal region, which is more conspicuous on the under side of the hind wing). 
The right fore wing, however, presents on its upper surface a complete mélange of the colours of the two sexes: 
the base, however, being masculine; whereas the under surface of this wing offers no distinction from the ordi- 
nary under side of the male.

In Mr. F. Bond’s fine Collection is preserved a specimen of this common British species, which in size and 
general appearance, as well as in the structure of the fore legs, is a male insect, but of which the left fore wing 
does not exhibit the peculiar male rugose portion of the dise to its full extent!, whilst the apical portion is 
marked as in the female. 
Mr. F. Bond also possesses a male specimen of this species, with the apical half of all the wings marked as 
in the female. 
Famity—MORPHID. 
In Mr. Hewitson’s Collection is preserved a specimen of Morpho Sulkowshyi Koll. (11. Ganymede, Westw. 
Gen. D. Lep.), in which the fore and hind wing on the right side, and the fore wing on the left side, are mas- 
culine. The left hind wing, however, on the upper surface has two-thirds of the basal portion blue, but not quite 
so brilliant as the right fore wing; the apical one-third of the wing (as far as and including the ocelli, as seen 
through the wing) is pale brown, with two narrow subapical bands not at all lunulate; the anal patch is as in 
the male, but much more diffused with brown; the black and red markings as in the male. 
On the under surface the left fore wing is throughout more strongly marked with darker brown, and the 
ocelli are rather larger than in the opposite hind wing. 
1 Tn this species the greater portion of the dise of the wing is covered with ordinary shaped oval scales, which are 
affixed to the wing in little cups placed transversely in rows at equal distances apart ; but in the rugose portions of the 
fore wings, characteristic of the male, the membrane of the wing is covered quite irregularly with a vast number of the 
small cups, the characteristic male scales or plumules (as they are termed by microscopists) occurring in these parts in 
vast numbers. These plumules are either of a very elongated oval form, or are almost linear, with the surface, however striated, 
and the apex terminating in a small tuft of very fine bristles. These scales are implanted in the cups by a minute bul- 
bous base, from which extends a short extremely slender cylindrical portion. Although, however, occurring in such vast 
numbers, these scales are not observed when the insect is at rest, or dried in a cabinet, the roughness which is observed 
in those parts of the wings being produced by usual oval scales implanted amongst them, sticking out as if thrust upwards 
by the dense mass of male plumules beneath.
