The eyes of this species during life are of a very pale grey. In many 

 specimens there is no black to be seen on the upper-side, but dark brown ; 

 this is, however, perhaps caused by the circumstance that such specimens are 

 not quite fresh any more. Many very fresh butterflies of this species, recently 

 received by me from Batavia are all dark-black without exception, also those 

 caught in the middle of the dry season. Snellen van Vollenhoven mentions 

 a specimen from Semarang with white marginal spots on the upper-side of all 

 the wings. 



W. J. Always common in the forest of Pademangan and other low-lying 

 localities in the neighboorhood of Batavia. In higher districts (3—14) not so 

 common, except in some years, as in 1867, when it frequently appeared. 

 Further more in the vicinity of Pelabouan Ratou (Wijnkoopsbay) (150) in the 

 south of the province of Prajangan. 



C. J. Semarang (4). I received also specimens from the province of Madioun. 



E. J. Very common in 1877— 1878 at Kediri (64). In the Leyden museum 

 there are also specimens from mount Arjouno and from Malang (445). At 

 Kediri I found in December the very gluttonous, and for that reason, very 

 quickly full-grown caterpillars on a kind of Capparis, which is called there in 

 Javanese wanouivannan and at Batavia daivon or kajoii foujoli. 



They show the ordinary Pieris form. Except the sides, which are covered 

 with short white hairs, they are smooth. The back is of a metallic hue and 

 dark lead-coloured, regularly spotted with larger and smaller gold-coloured 

 dots. Lengthwise, on the middle of the back and along each side, there is a 

 dark stripe. The chrysalis has also the common Pieris form. The head ends 

 in a long snout. It is white, or pale yellow, with black spots and dots, the 

 number and size of which differ a great deal, so that some pupas show only 

 black dots, whereas others are almost quite black. On the 6''^ or 7"' day 

 after pupating, the imago appeared. This irregularity in the increase of the
