fied as MiNEUs L. by Snellen, but after consulting Mr. Fruhstorfer and his 

 collection I am convinced that they must be referred to Moore's later species 

 HoRSFiELDL The clear white patch of specialized scales, duly observed by 

 Snellen, but incorrectly termed ochreous yellow by Moore, near the costa 

 on the upper side of the hind-wings in the d, distinctly separates this species 

 from Mineus L. In Mineus such a patch is indeed present but is covered 

 by pencils of long hairs, while in Horsfieldi also a similar patch occurs 

 which, however, is larger and more distinct and is placed at some distance in 

 front of these pencils of hairs. The figures given by Moore are, however, 

 poor and do not represent the species well ; the seasonal forms figured by him 

 are not to be traced, at least in Java. The d are generally darker in colour 

 than the 9, but there are some lighter ones also. Difference in colour or size 

 according to the dry or wet season is on the whole not to be observed but 

 considerable difference in the stage of development of the ocelli on the under 

 side does occur. Those most developed I find, the same as in M. Perseus F,, 

 in specimens captured in April near Wijnkoops Bay; moreover, these ocelli 

 are generally better developed during the wet than in the dry season ; I possess 

 several specimens with specially small ocelli, all taken during the dry season. 

 Amongst these even considerable difference in the degree of development exists 

 but in those least developed the ocelli are never reduced to white dots, and 

 I have individuals taken at the height of the dry season, both in the mountains 

 and in the lowlands, whose ocelli are equally developed as is usually the case 

 during the wet season. The individual unequal advance in colour development, 

 already referred to under Cyllo Leda L., therefore, exists here also, but a 

 separation into seasonal races I am unable to recognize. On the upper side 

 of the hind-wings of the 9 sometimes one and sometimes two ocelli are visible 

 or they may even be absent altogether. 



I have observed the larva on a//a/io allang (Imperata arundinacea Cyrill.) 

 and on a bamboo like grass. Some larvae are dark green with a pale green 

 lateral line, while in addition a dorsal and several dark and light longitudinal 

 lines are to be seen. The body terminates in two short, spinous, faint red 

 points. The head is reddish brown and furnished with two short stout points. 

 Another larva was reddish-brown with a faint dark dorsal line and a lateral 

 band, between which similar bands ran obliquely backwards; it was also strongly 

 chagreened. Yet another larva, likewise strongly chagreened, was light greyish 

 brown with a light line on the ventral margin and indistinct dark brown dorsal 

 bands, and with faint marking, resembling a linked row of rhombs, at the sides. 



The reddish brown larva before pupating turned to pale green. The pale 

 green pupa has yellowish white stigmata and is devoid of processes. It was
