C. J.? 



E. J. de Niceville gives this species as occuring in E. J. 



The specimen reproduced, the only one that I possess, is probably a male. 



Genus LYCAENA F. ') 



Snellen, as is the custom with Lepidopterists, gives the expansion of 

 each species in this genus in m.m. I shall not follow him in this, as I do not 

 attach much value to these measurements; seeing that in the specimens of 

 many species there is a great variety in size. I do not wish, either, to adopt 

 the so-called key as prepared by Snellen for distinguishing these species. 

 As in his systematic arrangement he does not accept the subgenera proposed 

 by various writers, because, in his opinion they do not bear sufficiently constant 

 characteristics, and the key aspires to arrange 52 different species, it cannot, 

 in my opinion, with al its divisions and subdivisions fulfil its object of avoiding 

 confusion on the subject. I attach more value to faithful reproductions, of 

 which there is still great need, for although Druce, Bingham and de Niceville 

 have done much good work in this respect, — Swinhoe's reproductions as a 

 rule, leave much to be desired — it is by no means certain that the specimens 

 to be found in Java of the same species are exactly the same as those repro- 

 duced by them. I shall, therefore, make a particular point of the illustrations. 



Where Snellen has described new species I consider that his descriptions 

 translated into English, as they have so far appeared in Dutch only, should 

 be included in the revised and abbreviated form which he prepared afterwards 

 for this monograph on the Java rhopalocera. 



') DE Niceville also gives the species Zalmora Bull. I myself do not know any 

 Java-specimens of this.
