50 ME, G. T. BETHUNE-BAKEB : A REVISION OE THE 



$ . Upperside : both wings dark brownish, the primaries with a large patch of very 

 pale iridescent blue from the discoidal to the submedian nervure and slightly on to 

 the internal margin ; in the posterior area a patch of white shows through the blue 

 iridescence ; there is a large dark spot closing the cell, which also shows through the 

 iridescence and off which the blue scales are liable to get rubbed. Secondaries with 

 the pale blue iridescence not extending quite so far towards the posterior margin. 

 Underside as in male, but with paler ground and darker spots (in contrast) and the white 

 encircling broader. In the primaries the spots over the middle discal spot and up to 

 that closing the cell are quite distinct though irregular in shape, and the submedian 

 area is whitish. In the secondaries there is a half basal spot on the extreme internal 

 edge of the costa. 



The type of this species, a single female, was described by Felder from Amboina. I 

 have therefore described a male from that island and also a female agreeing almost exactly 

 with the type ; the colour of the underside is not, however, constant in examples from 

 the same locality — some from Amboina being quite pale brown, others dark brown ; the 

 pattern, however, appears not to be subject to variation. In the female the pale upperside 

 patch occupies a greater or less area in different specimens quite irrespective of locality. 

 Dr. Staudinger has described a variety from Palawan as var. dilutior, of which I have 

 the type male and female before me; the male is precisely the same as Amboina 

 specimens of eridanus Feld., and the female differs only in the extent of the pale 

 upperside, which is slightly greater than in the type — this, however, varies in different 

 specimens. Herr Rober has also described his species polita from Ceram (Iris, I. c), 

 the type of which is also before me, and it is absolutely the same as a specimen from 

 Amboina, so that both these names must sink. I have before me, through the kindness 

 of Mr. Cator, a series of eight specimens, four males and four females, from Cagayan, 

 which present no differences from eridanus Feld., except that the tone of colour of the 

 male is distinctly bluer than usual. Dr. Staudinger calls his var. dilutior a small local 

 form of eridanus Feld. ; this remark no doubt arises from the fact that he had not 

 differentiated this species from the large padus of Felder, the two former being similar in 

 size as well as colour and pattern. The genitalia are very similar to those of A. padus 

 Feld., but the hooks attached to the lower part of the tegumen are recurved, as shown 

 in Plate IV. fig. 13.

I have not seen this species, which is described from specimens in Dr. Holland's 

 collection. I admit it with some doubt, believing it will turn out to be merely a slight
