close together. From pupae of 27 April and 20 May the imagines emerged 

 on 6 and 28 May. 



Moore's figures of the imago are good but those of Kobus poor. None of 

 the figures of the larva referred to appears to me a good likeness, nor are those 

 prepared for me. On the other hand I am able to reproduce here (PI. XV, 

 fig. 3 If), a very successful figure of the larva of Cyllo Suyudana Moore which is, 

 indeed, larger than any specimen of C. Leda L. I have ever seen in Java but in 

 which, otherwise, I can discover no characters differentiating it from that species ; 

 it is true the white lateral band along the ventral boundary is particularly 

 distinct and evidently somewhat raised, but similar bands sometimes occur in 

 the larva of C. Leda L. Like that of the latter it is rugose but this is 

 difficult of reproduction, which is clearly proved by Kobus' figure.

Fruhstorfer confuses this species with Phedima of Cramer which represents 

 a badly coloured 9 of C. Leda L. ; his alleged seasonal forms, consequently, 

 are of no value. I possess this butterfly from West, Central, and East Java, 

 the majority of specimens being from the mountains, but one was captured in the 

 prov. Semarang, very near the north coast, in low lying country, therefore. I 

 have long been in doubt whether this species should not be considered a form 

 of Cyllo Leda L. A careful comparison of 19 specimens of the present 

 species has, however, satisfied me that, even when closely allied to Cyllo 

 Leda L., it constitutes an independent type, although one specimen may be a 

 little darker and another somewhat lighter on the upper side, while on the 

 under side also they differ and the pointed appendage of the fore-wings is very 

 pronounced in some individuals, whereas in others it is entirely wanting. 

 Although the manner in which the evolutional modification of its under side 

 is effected recurs in C. Leda L. no transitions between these two species are 

 met with. A careful examination of the genitalia of these butterflies conducted 

 on my behalf by an expert on the subject. Dr. Henri de Graaf of Leyden, 

 revealed the fact that of these i g specimens only 2 were V and that the latter
