condition it has a patch of lemon yellow on each side of the abdomen. This sp. must have been 
much more frequent when Commander Walker was in Hongkong in 1892-3. He took it from 
January to April, and says it flies close to the ground along shady paths. 
Fig. 2, PI. viii is from a $ taken in August, at Lantana flowers. 
Danais (Radena) similis, Linnceus. 
The commonest sp. of Danais here, flying throughout the year, and found almost every¬ 
where, though it is fond of trees and shade and very partial to flowers. The sexes are alike, and 
the $ has no scent-sac on the hindwing, though it is provided with the usual anal scent-gland. 
Fig. 5, PI. 1 is from a £ taken in December, but this insect scarcely varies seasonally. 
The egg is yellowish white, striated longitudinally, about twice as long as broad, laid 
singly on stems, tendrils or leaves of the foodplant, Tylophora hispida , D.C., a twiner, Nat. 
Ord. Asclepiadece , only known at present from Formosa and Hongkong. 
The larva is figured on PI. ia, Fig. 7, the pupa Fig. 8. In the latter figure the bluish 
colour on the band and spots represents silver. Larva just hatched whitish, showing tentacles as 
black dots. Head black. The larvae always seem to rest on the underside of the leaves. 
Danais (Salatura) plexippus, Linn. 
More often known, perhaps, as genutia , Cram ., but plexippus is the older name. A 
very common butterfly, especially in autumn, but found everywhere throughout the year, and very 
fond of flowers. It is a beautiful and conspicuous sp. and common enough to brighten up many a 
forlorn and sordid spot round the filthy native villages. This insect, with D. similis , the two com¬ 
mon sp. of Euplxa and a few D. limniacce swarm on the twigs and leaves of bushes and trees in 
sheltered nooks during November, where they cling all day if the weather is dull, rising in a dense 
cloud if disturbed, but soon settling again. I have never noticed any D. chrysippus amongst them. 
These gatherings are dispersed before the end of December, when many butterflies will be found 
dead beneath the bushes. 
Fig. 8, PI. I is from a £ taken in November. The % is like the $ but is without the 
scent-sac on the hindwing. 
Egg, about twice as long as broad, striated slightly longitudinally, laid singly on the under¬ 
side of leaves of the foodplant, Asclepias curassavica. The larva and pupa will be described later, 
as I have only recently obtained the eggs of this butterfly, but the larva just hatched is white, with 
three pairs of tentacles, as in D. chrysippus , just showing as brown dots. Head black. 
Danais (Anosia) archippus, Fabricius. 
Merely an accidental visitor at present, occurring at long intervals, but it is one of those 
butterflies which seem to be gradually spreading over the globe. Its original habitat is N. America, 
but it appears to be very closely allied to the S. American D. erippus menippe-t Hiibner.
