Hal. Queensland ; Aru ; Waigeoe ; Woodlark Island ; Fergusson Island ; Tokal 

 Key ; and New Guinea. 



Expanse, 6 47-54, 2 48-58 mm. 



6 . Upperside : both wings brilliant morpho-blue, shading into purplish towards the 

 costal and posterior margins of the primaries and towards the posterior margin of the 

 secondaries. Costa of primaries narrowly black ; posterior margin broader, increasing 

 in width at the apex. Costa of secondaries broadly blackish ; posterior margin narrow, 

 abdominal fold entirely brownish ; tail black, tipped with white ; lobe scarcely deve- 

 loped. Underside: both wings reddish brown, with all the spots of a darker hue with 

 pale margins. Primaries : inner marginal area paler brown, apical area washed with 

 very pale pinkish lavender; three discal spots increasing in size, the upper portions of 

 each side of which are margined with pale silvery bluish, the usual two spots below the 

 discoidal cell ; transverse band continuous, inclined outwards, terminating on the lower 

 median nervule, below which, but unconnected with it, are one or two semi-coalescent 

 spots shifted well inwards ; submarginal row of darker spots very indefinite ; the upper 

 and apical areas are dusted over with grey. Secondaries with a broad subcostal streak 

 of pinkish lavender, with the four basal spots followed by the three large ones as 

 usual; cell closed by a large quadrate spot, below which is a small spot filling the 

 terminal space between second and lower median nervules. Transverse band unbroken, 

 extending round up to the internal nervure ; the outer edge of this band is very jagged 

 and irregular. Submarginal shading continuous, between which and the band is 

 a broad space of grey. Margin rather broadly and very darkly bordered ; anal spot 

 small, black, surmounted by slight green iridescence, which extends slightly over the 

 marginal area between it and the second median nervule. 



S . Upperside : both wings brilliant, slightly greenish morpho-blue ; primaries, very 

 broad apical and outer marginal areas and a narrow costal margin black. Secondaries 

 with costa and apical margins very broadly blackish ; posterior margin not so broad, 

 but increasing in width at the anal angle ; abdominal fold brownish. Underside as 

 male. 



I have another form of the female which has the blue darker, almost like the male, 

 but a shade paler perhaps. 



The genitalia have the clasps peculiar, with excised extremities ; the penis has a 

 globular orifice.
