which are dark on both sides and others which are light brown ; generally 

 the d* are, indeed, darker, but otherwise I am unable to detect any difference 

 according to period of capture or habitat. Specimens either with large or 

 with less developed ocelli are met with in both sexes; amongst these occur 

 individuals with strongly developed ocelli taken at the height of the dry season 

 and others with least developed ocelli caught in the wet season. Specimens 

 such as Moore figures as the dry-season form I have never found in Java. 



The caterpillar was repeatedly found on a//ang-a//ang (Imperata Arundi- 

 NACEA Cyrill.) and according to de NiciviLLE occurs on />adi (Oryza sativa L.). 

 Fruhstorfer informs us that Martin found the greenish-white globular eggs 

 on the under side of leaves of various grass species ; he also relates the whole 

 life histor}^ of the caterpillar according to Martin's observations. 



I found them to be of a type such as occurs in some Debts larvae, with 

 long processes on the head and the hinder portion, the latter being sometimes 

 closely appressed. Some are greyish-green with a dark dorsal line, a faint 

 jellow subdorsal line and a clear white band at the ventral margin. With the 

 aid of a lens it is seen to be covered with short black hairs. The head 

 resembles ground glass and the horns are red, darker at the base and under 

 a lens it is also observed to be covered with short stiff hairs. The posterior 

 processes are faint rose. Another caterpillar was white with a raised white 

 stripe on the ventral margin, the horns and posterior processes rose. Yet 

 another caterpillar W'as entirely of a beautiful rose colour, including the horns 

 and posterior processes, with the stripes already alluded to. This caterpillar 

 had the head like ground glass but darker. The pupa is attached to a grass 

 stem and is light brown with longitudinal dark brown stripes ; the head termi- 

 nates in two sharp points mostly closely appressed in the same manner as is 

 the case with the posterior processes. According to Martin the imago emerged 

 after nine days in the fore-noon. 



The figures given by Moore of the larva and pupa of O. Man data Moore 

 from British India and Ceylon closely agree with mine of O. Medus F.

As is the case in the genus Cyllo, in the present genus a universal darkening 

 of colour appears to occur which subsequently again gradually diminishes. 

 Vestiges of the original red are, in fact, present in some species. The general 

 colour in several species as a reddish or brownish grey which in some indi
