family relationship of all. The females may at the same time he lurk- 
ing hard by in the jungle, though in smaller numbers, a few of them 
sometimes joining in the flight of the males. I have often obsei-v- 
ed males flying alone with expanded tufts, and I suppose they are trying 
to attract the female from a distance, appealing rather to her sense of 
smell than that of sight. In the presonce of the female, the male keeps 
his tufts in continual action, and whether of dark or bright colours, 
they may well be as attractive to her eyes, as the plumes of the cock 
grouse or peacock are to his hens. The eyes of butterflies are so pro- 
minent, that though the female never faces the male, but keeps gliding 
on just before him in coy rotreat, I cannot think that any grace of his 
escapes her notice. But her sight is probably not so strong as to re- 
cognize these ornaments at a great distance. So that the attractive 
colours are presumably intended to take effect at close quarters only, 
while with a favourable wind the odour is no doubt perceptible far 
away. I myself cannot generally make it out more than two or three 
feet away. But the forefeet of female Banaidce seem to be developed 
into a powerful organ of smell, and even apart from this, that sense 
must be keen in all butterflies, since they are attracted from long 
distances by the scent of flowers. And few flowers are so flagrant 
as these insects.

1. Nectaria leuconoe, Erichson, var. engania. This slight variety 
seems darker than the typical N. leuconoe, as figui’ed by Doubleday, just as 
N. clara (as figured by Herr Semper) is much lighter. The base is but 
slightly touched with creamy, and more so in the female than in the 
male. The dark lines in the cell of the forewing are distinct, the black 
transverse area there narrower and more quadrate than in leuconoe , the 
discal dark markings aro more connected, and those on the hindwing are 
more triangular, the wedge-shaped white spot near the lower angle of 
the forewing is distinct, and in general the markings are very clearly 
cut and distinctly outlined. The male has two large whitish abdominal 
tufts, each with a minute rudiment of another near its outward base. 
2. Macroi’Uka cokds, Fabricius, var. Micronesia. Somewhat re- 
sembling M. corns (elisa), with the size and shape of ill. phaibus. Male, 
forewing with the spots minute, one in the cell, seven in a bent discal 
series, and ten submarginal dots. Hindwing with two or three discal, 
and one or two subapical dots. Below, forewing with a dot in the cell, 
two large discal Bpots with a dot below them, two subapical dots, and
