The species differs particularly, as Bingham quite correctly observes, from 

 its allies in Java — /. c. M. Horsfielpi Moore — by the peculiar bending 

 of three of the ocelli on the under side of the hind-wings. In the figure in 

 Seitz, die Grossschm. d. Erde, 92a this feature has been completely overlooked. 

 In my figure I have indicated it (PI. XVII, fig. 54a). 



The species is very common in Java. As in the case of Horsfieldi 

 Moore, darker and lighter individuals occur, the d* being usually somewhat 

 darker but this has no reference to the seasons. The same applies to the 

 ocelli. Specimens with small ocelli occur, smaller in some than in others ; 

 these have been described by Fabricius as M. Blasius. In a specimen from 

 Tjampea I find the ocelli most reduced, being partly resolved into white dots. 

 I possess such specimens with small ocelli caught in may at Pouspa in E. J. 

 and in August — therefore, in the middle of the dry season — at Semarang, 

 but likewise some captured about the same time at Batavia and Semarang, 

 with well developed ocelli, and a 9 taken at Semarang in September where the 

 stage of development is, so to speak, intermediate. The development of the
