ocelli I found most advanced, here as in Horsfieldi, in specimens caught in 

 April near Wijnkoops Bay. 



I have also taken at Batavia on the same day in the rainy season two c?, 

 in one of which the eye-spot on the upper side of the fore-wings is very 

 distinct while in the other no trace is to be seen of it. Some of my other 

 specimens agree with the first and some with the second. As regards the row 

 of ocelli on the under side of the fore-wings I found amongst 43 specimens 

 many with only two, some with three or four, but only one with five ocelli 

 as in the accompanying figure. The small lower eye-spot is mostly wanting. 

 From this it will be seen to what extent the number of ocelli varies in the 

 same species — which is also the case with the European species of Satykus — 

 and that, consequently, there is no justification for basing forms or species on 

 the number of these. The attendant circumstances in this and the preceding 

 kind are doubtless indentical with those pointed out under Cyllo Leda L. ; 

 the rainy season indeed greatly promotes this development but only in the 

 individuals which have acquired susceptibility for it through evolution, while in 

 the case where the stage of evolutional change has progressed very considerably 

 this will manifest itself even in individuals making their appearance in the dry 

 season. Definite wet-and dry-season forms or races do not, therefore occur. 

 Much light is still required on the subject, not only as regards the genus 

 Mycalesis but in connection with Debts and Ypthima as well and we must await 

 further observation and breeding. Although I have numerous specimens at my 

 disposal, by far the great majority of them have been carefully labelled only as 

 regards the habitat but not as to the time of capture ; it was only during the 

 latter part of my stay in Java the importance of these data became manifest to me. 

 On one occasion I bred the imago from a larva living on allang allang 

 (Imperata arundinacea Cyrill).
