those in cell 3, not in front, as in Ardates; moreover those in cells 3 and 5 

 do not protrude much outwards as in Ardates. Markings and black spot in 

 eel 2 of the secondaries are the same as in Glauca : fringe-line dark grey, 

 edged fine greyish white. Fringe grey, on the underside somewhat lighter 

 than the wings, with a faint darker line over the root. 



It is not impossible that Nacaduba Aluia which Druce has described 

 in Proc. Zoo/. Soc, London, 1895, /. 578, with an illustration on plate XXXII, 

 should be included in this species. It is true that it has a tail, and Datarica has 

 none, and that while the size corresponds, the colour, as shown in the illustration 

 referred to does not correspond to that of Datarica. At the same time I must 

 here remark that Snellen calls the colour of the upperside of the 6 dark blue, 

 while in all my (3 specimens it is distinctly dark brown. Is it possible that in 

 specimens which have been kept for a long time the colour becomes darker?

The many specimens which I procured in Java are all tailless, and in 

 this respect agree with the above mentioned illustration by Moore, but not 

 with his description of Ardates as it mentions small tails on the secondaries. 

 De Niceville calls this species the tailless form of Ardates; Bingham is of 

 the same opinion, but Snellen does not agree with this, and therefore suggests 

 for this species the name Subardates. For reasons which I have explained in 

 the Introduction, I do not share Snellen's opinion in this matter, and have 

 therefore restored the name of Ardates to this species. The sexes do not 

 differ from one another.
