10. Radena longa, n. sp. PI. I, Fig. 2. A local form of the 
Javanese B. juventa. Forewing very long, falcate, the white markings 
mostly elongate and reduced, cell of forewing with the basal mark 
slender, clavate at tip, the outer one small with the upper streak absent, 
the disoal spots beyond the cell much reduced. Hind wing, with the 
white area in the cell broken by two dark lines, the upper wide, the 
lower slender, not quite continuous ; all the discal spots beyond the 
cell slender and elongate. 
11. Radena macra, n. sp. PI. I, Fig. 4. A local form of B. vulgaris, 
the forewing elongate (but shorter than in B. longa), falcate, cell with the 
basal mark bifid, the upper streak slender, not so long as the lower, the 
outer spot narrow at its upper end, with a minute spot adjoining it 
above, and without the slender prolongation present in B. vulgaris ; the 
three spots beyond the cell greatly, and all the others more or less 
reduced in size. Hindwing with all the spots reduced, that in the cell 
simply bifid, without any spot in the bifurcation (such as occurs in 
B. vulgaris). The submarginal dots are wanting on the apex of the fore- 
wing above and below. 
These two Badenas are about equally common, and are found to- 
gether. In the island of Sembawa, east of Java, two Badenas also 
occur, but in this case the juventa form is restricted to higher altitudes, 
though there is a zone in which both are found. These facts surprised 
me as I had supposed juventa, like vulgaris, to be simply a local form of 
B. similis. 
The anal tufts of B. vulgaris and macra are shorter than in any other 
Danaid, the hairs white at the base and grey outwardly. In B. juventa 
and longa, they are nearly twice as long and grey throughout. 
All the Enganese species of Danais are distinguished by their 
elongate form. This is also the case with several groups of butterflies 
in the Celebes, as shown by Mr. Wallace.

12. Lethe europa, Fab. scarce. 
13. Melanitis leda, Linn, (ismene). My specimens were dark and 
nearly unmarked above, but of the usual shape. Both the ocellate and 
the non-ocellate forms were taken.
