74 ME. G. T. BETHUNE-BAKER : A REVISION OF THE 



tail long, dark fuscous, tipped with white, nervures on each side of this being slightly 

 elongated into a tooth-like projection. Underside : both wings greyish ochreous 

 brown, with very dark brown, almost blackish spots encircled with whitish. Primaries 

 with three increasing cell-spots ; above the third a small one near the costa, and below 

 it (the third) a large one in the lower median angle ; a very large subdiscal spot, with 

 a pale centre in it ; submedian area pale grey. Transverse band composed of seven 

 spots, highly dislocated between the fourth and fifth ; the second spot is large and 

 shifted outwards as to its outer margin only, third spot smaller with its outer margin 

 consequently inwards, fourth spot shifted somewhat outwards altogether, fifth spot 

 shifted right inwards, with its outer margin on the inner margin of the fourth spot, 

 sixth long spot shifted slightly outwards, seventh spot shifted inwards, but with an 

 outward inclination ; submarginal row distinct, but indefinite. Secondaries with a spot 

 at the basal costal extremity ; four basal spots, the lowest shifted inwards, followed by 

 three larger spots below each other ; cell closed by a large quadrate spot, below which 

 is another connecting it with the lowest of the three afore-mentioned ; above this cell- 

 spot, touching it, are two large spots above each other, extending up to the costa ; 

 these usually form the first two spots of the transverse band, but in this species they 

 form an inner fascia with the cell-spot, the small one below it, and the third spot of the 

 series of three. Transverse band beginning on the discoidal nervure, composed of four 

 spots and a large crook-shaped mark ; the second spot is shifted outwards, third 

 slightly inwards, fourth slightly outwards, the crook-shaped mark, composed of the 

 angular spot and long spot combined in one, shifted right inwards and extending 

 nearly up to the lowest of the basal spots. Submarginal row indefinite ; lobe-spot 

 deep black, with a slight black marginal spot in each of the next two nervure 

 interspaces, over which latter are superimposed greenish-metallic scales, which also 

 edge the lobe-spot above ; between these and the transverse band there is a slight 

 scattering of greenish-grey submetallic scales on a darker background. 



2 . Upperside : both wings a little bluer than the male ; primaries with broad 

 costa, broader outer margin, and very broad black apical area .; cell closed by a black 

 dash : secondaries with very broad black margins all round. Underside : both wings 

 precisely as in the male. 



This species, of which I have five specimens before me, is nearest silheteusis Hew., 

 but may be readily distinguished by the paler violet-blue and the very narrow black 

 borders to the primaries ; beneath it is much paler and greyer, whilst the blackish 

 spots, all standing out most prominently, make it recognisable at a glance.
