in the cell, is a dash of purplish iridescence. Under surface : 

 both wings pure white : primaries markless : secondaries with 

 a trace of a very fine subterminal dark line more distinct at the 

 tornus ; a bright red terminal spot between veins 2 and 8 ; 

 the lobe-spot (which on the upperside is black with bright 

 green metallic scales) is small, on the inner margin bril- 

 liantly metallic-blue, green, and mauve, edged above with a 

 red lunule, from which is a short, fine, dark line to the inner 

 margin ; three tails edged and tipped with white, the upper 

 one on vein 3 being a long tooth. 



Expanse 37-38 mm. 



This species, though not the brightest, is yet one of the 

 loveliest of a lovely genus : it is quite impossible to describe 

 the blue, and I have not attempted to do so ; it shades from 

 every tone of blue that can be imagined into greenish, 

 becoming almost bronze in certain lights, and is brilliantly 

 lustrous in most positions.

Arhopala halmaheira, sp. n. 



^ . Both wings lustrous pale silvery blue, bluer towards 

 the termen. Primaries with a fine black costa, increasing very 

 slightly near the apex ; apex rather broadly black for a very 

 limited area, termen narrowly black, fringes blackish : 

 secondaries with costa broadly brown; termen narrowly 

 black ; inner margin whitish grey to vein 1 b, deepening to 

 dark grey at the tornus; tail black, tipped with white. 

 Under surface : both wings brown, slightly tinged with 

 purple, with darker spots finely encircled with white. Pri- 

 maries with three increasing cell-spots, that closing the cell 

 large and irregular, below which is a large spot in the angle 

 of vein 2 ; catenulated band consisting of six spots increasing 

 in size from the costa to the fifth spot, the upper three nearly 

 round, the lower ones irregular ; a broad definite submargiaal 

 band of uniform width, edged on the interior with whitish ; 

 a dark linear termen ; area below vein 2 pale up to the sub- 

 marginal band ; fringes grey, darkly tipped. Secondaries 

 with four basal spots, the third shifted outwards and the 

 fourth inwards ; three large spots below each other, the middle 

 spot being in the centre of the cell, a largo spot closing the
