I possess many specimens of this species, not from the low lying country 

 of northern Java but from the mountains, and likewise from the lower districts 

 near Wijnkoops Bay on the south coast. They comprise light and dark 

 coloured, large and small, with more or less pronounced ocelli, all having been 

 caught either at the height of the dry or during the wet season, so that I find it 

 impossible to trace in these differences in colour development any relation either 

 the place or time of capture. Only the light coloured $ specimens from the 

 Prayangan mountains appear to me to be the largest with the most strongly 

 developed ocelli. I can, therefore, see nothing but individual differences of 

 colour evolution in the various races of this species established by Fruhstorfer, 

 any more than in the species Nigricans proposed by Snellen and Fruhstorfer. 

 In the numerous specimens of the latter from E. and W. Java, in my possession, 

 mostly taken during the dry but also in the wet season, I can only recognize 

 smaller, less developed individuals of Pandocus ; not a single definite feature 

 characterizing either form can be traced since in large series they may, distinctly 

 be seen to run into each other. Breeding may ultimately settle this matter. 



This butterfly is very common in the mountains flying low near the ground 

 amongst the underwood, even when there is no sun or during rain. Some 

 9 attain an expanse of wing of 45 mm. The larva feeds on a//ang a//ang 

 (Lmperata arundinacea Cyrill), bamboo (Bambusa sp.), and roumpoid pah it 

 (Paspalum conjugatum Berg). The colour dimorphism, referred to in the 

 introduction, is met with in these caterpillars, since there are loam- or brick- 

 coloured as well as light green individuals. They exhibit a dark dorsal stripe
