There are larger and smaller specimens, but I see no difference between 

 specimens from W. J. and from E. J. The underside of the c? differs from 

 that of the 9 only in being somewhat darker. 



W. J. Batavia (3 — 14); Depok (95); vicinity of the Wijnkoopsbay or 

 Pelabouan Ratou (+ 150). 



C. J. Touban on the north coast; Province of Tegal.

The accompanying illustrations of both sexes are made from specimens 

 captured by Fruhstorfer in E. J. The species is unknown to me. He 

 considers it to be a subspecies, which he calls Tryphiodorus Cram.

W. J. In the Leiden museum there is a c? captured by S. Muller in 

 the Province of Krawang. 



C. J. Province of Madioun (± 500). 



E. J.? 



This species would therefore seem to be rare. On the underside both 

 sexes are alike. 



20. Pavana Horsf. (PI. XXI, a, b, c, d). 



A good deal of confusion exists between this species and the following 

 one, as they considerably resemble one another, and are both subject to a 

 process of colour evolution, which, especially in the female, leads to great 

 individual variations, so that the colour can only to a very limited extent be 

 taken as a specific characteristic. Not only that the colour of the upperside 

 in the (3 is sometimes more bluish and at others more brownish, but on the 

 underside also, although otherwise the same in both sexes, the colour is more
