 a specimen from Ambarawa (500) in the mountains of C. J. Fruhstorfer 

 caught the butterfly on the plateau of Pengalengan ( — 1700) in the province 

 of Prajangan in W. J. and is also in possession of a specimen from the sur- 

 roundings of Lawang (500) in E. J. The early stages are unknown. 



Genus CALLIDRYAS Bsd. 



Strong butterflies which like to sit down on wet sand. In Java the cater- 

 pillars seem to live by preference on different species of Cassia, the same 

 food-plant is mentioned from Ceylon by Moore; Scudder mentions it also of 

 the North-American C. Eubule L., Stoll of the South-American C. Mar-

 Depok (95) and at Buitenzorg (265). But in 1908 I received a large collection 

 of Rhopalocera, all caught in the lowest quarters of Batavia and among these 

 also many specimens of this species. I also received some from the localities 

 adjacent to Pelabouan Ratou (Wijnkoopsbay). 



It then made the impression on me that in these latter years this species 

 has become much more common than formerly.

According to Dr. Martin this species occurs in Sumatra in the lower

 Moore in Ceylon these butterflies are said even to appear every year in great
