On the upperside of the male of this species the darkening process has 

 developed in the same manner as in the above mentioned species ; the relic- 

 stripe is also very distinct. But the underside has become darkened to a 

 uniform light brown colour. 



From various districts of W. Java I procured 7 specimens, all males. The 

 female is still unknown. But I possess 6 specimens of a species as yet never 

 described, which, it is true, do not resemble these males, but are more like 

 the female of A. Unicolor Felder and also A. Waterstadti Druce, but which 

 are all females, and were caught in the same districts of W. Java as Portunus. 

 Moreover, the peculiar characteristic of the male, the light brown colour of the 

 underside, is also present in them, although in a much less degree, only along 

 the edges, and particularly upon the apex of the primaries ; thus distinguishing 

 this butterfly from the female of A. Unicolor Felder distinctly and uniformly. 



For these reasons, I think that this female, of which I here give a good 

 reproduction, may for the present be taken as the female of A. Portunus. 

 Fruhstorfer believes that he has in his possession a 9 of the same as the c? 

 of this species and considers the 9 reproduced by me to be that of A. Strigatus 

 Moulton which I do not know, and of which I never found a c? in this neigh- 

 bourhood.

In this species, of which I only possess one specimen from Java, the 

 darkening of the upperside has developed to a uniform brown, upon which 

 the relic-stripe is also faintly visible. On the underside the white is only a 

 litde obscured by a few dark scales, and thus is still pretty clear; but on the
