These insects fly amongst the underwood mostl)' close to the ground ; many 

 belong to the commonest Rhopalocera of Java. Considerable individual differ- 

 ence occurs in the size of the white and brown spots and streaks in the same 

 species. The larvae are furnished with processes similar to those occurring in 

 the genus Euploea but they are shorter and less numerous. The anterior pair 

 of these processes is movable, according to Wood Mason ; I have, in fact, 

 observed this in a couple of species ; if, however, we take into account the 

 great number of Danias larvae I have reared it must be assumed that this is 

 of rare occurrence, as has already been stated with respect to Euploeas. The 

 colouring of the pupae has already been dealt with in the introduction. According 

 to Moore some of the species, amongst these D. Genutia Cram., very common 

 in Java, and D. Chrysippus L. in British India, belong to the migratory butter- 

 flies, but this is not the case in Java.

A mountain species, very common everywhere in the upper mountains 

 above 1 000 metres altitude, where it may frequently be observed flying swiftly 

 close to the ground in the dark forest. Fruhstorfer found this butterfly on 

 Mount Gedeh as high up as 2600 metres and distinguishes the E. J. specimens 

 as GiLVA from those of W. J.
