Hob. Mindanao.

d . Upperside : both wings exceedingly deep purplish indigo-blue, with a dead lustre 

 in certain lights ; in a side light the blue is scarcely visible at all : primaries with the 

 brown costa not very broad, but the nervules appearing in the blue as brown lines ; 

 outer margins very broad brown, the blue being rather sharply defined on its outer 

 edge : secondaries with the brown costa extending nearly to the cell, and the outer 

 margins exceedingly broad, especially at the apex and the anal angle. Underside : 

 both wings slightly rufous brown, with scarcely darker markings palely margined. 

 Primaries with an indistinct spot in the middle of the cell and one at the end, below 

 which is a very indistinct one in the lower median angle ; transverse band almost 

 straight, but with an outward inclination, composed of six small confluent spots of 

 about equal width; occasionally there is a very slight bend at the fourth spot ; sub- 

 marginal row fairly distinct ; marginal row almost obsolete. Secondaries with four 

 small basal spots below each other, the third shifted outwards, followed by four 

 rather large spots below each other, the fourth being really the eighth spot of the 

 transverse band ; cell closed by a quadrate spot, below which is a small one in the lower 

 median angle ; transverse band consisting of seven spots, the second the largest directly 

 below the first, but with its outer edge shifted outwards and touching both the spot 

 closing the cell and the third spot of the band, which last is shifted right out on to 

 its outer margin, fourth spot shifted outwards again, fifth spot slightly inwards, sixth 

 slightly outwards, seventh spot very slightly angled, shifted inwards ; submarginal row 

 distinct, marginal row less so. 



2 . Upperside : both wings mauvish brown ; primaries with a small violet patch 

 occupying the cell, the subdiscal area, and a very little of the submedian area ; 

 secondaries with the cell only occupied by some subdued indistinct violet scaling. 

 Underside as in the male. 



This species may be at once distinguished from catori mihi by its much smaller size, 

 the very exceptionally deep purplish blue, with yet broader borders, and by its straight 

 transverse band on the underside of the primaries. From avatha de Niceville the 

 exceptionally deep and dark colour of the upperside will at once separate it, as well as 

 the more distinct markings of the under surface.
