5 . Upperside : both wings bright violet-blue ; primaries with a 

 dark spot at the end of the cell and exceedingly broad brown 

 margins all round ; costa brown to the cell, and almost to the 

 upper median nervule ; secondaries with exceedingly broad costa 

 and very broad outer and abdominal margins. Underside exactly 

 like the male, but darker in colour. 



This species will precede A. arsenitts, Teld. 



Ariiopaia watbhstrabti, sp. n., Bethune-Baker. (Plate XXX.

d . Upperside : both wings lustrous bright blue tinged with 

 violet, in some lights the colour being dark violet-blue ; primaries 

 with costa narrowly, and outer margin less narrowly black ; 

 secondaries with costa less broadly than usual, and outer margin 

 very narrowly black. Underside brown, with slightly darker spots 

 palely edged. Primaries with pattern rather indistinct, with three 

 increasing cell-spots, the first near the base, below the second is an 

 indistinct and indefinite spot, and below the third is a small indis- 

 tinct one : transverse catenulated band composed of six spots, 

 ending on the lower median nervule ; the upper four are each 

 inclined obliquely outwards, but not fractured ; the fifth is shifted 

 inwards very slightly as to its outer, but more so as to its inner 

 margin ; the fifth is shifted outwards ; submai-ginal band very 

 indistinct ; submedian area paler. Secondaries with pattern more 

 distinct than in primaries ; four basal spots below each other, the 

 third shifted outwards, followed by three larger spots below each 

 otlier ; cell closed by a subquadrate spot, below which is a small 

 spot in the lower median angle : transverse catenulated band com- 

 posed of eight spots from the costal nervure ; the second largish, 

 shifted well outwards and slightly dislocated from the third, which 

 is shifted right outwards ; fourth shifted outwards again ; fifth 

 inwards, and having a very oval exterior margin ; sixth outwards, 

 with a straight margin ; seventh angular spot dislocated right 

 inwards, eightli slightly inwards ; submarginal row fairly distinct ; 

 anal area darker, with superimposed pale bluish-green metallic 

 scales. 



$ . Upperside : both wings bright lustrous azure ; primaries 

 with rather broad costa and very broad black outer margins ; 

 secondaries with broad even black margins all round ; abdominal 

 fold greyish. Underside just like the male, with two exceptions, 

 viz., that there is a trace of a spot on the costa over the third cell- 

 spot in the primaries, and in the secondaries the second and third 

 spots of the transverse baud are not dislocated. All the other 

 markings are exactly the same in every particular. 



This species will follow A. metamuta, Hew., but it can easily be 

 distinguished by both wings being the same colour.
