species in the forewing being more elongated, the inner margin being longer than 

 (instead of the same length as) the outer margin ; the discoidal cell is longer and 

 narrower, the second median nervule arises nearer the lower end of the cell ; there i.-; 

 also a greater space between the origins of the first and second median nervules. tln^ 

 sub-median nervure is straight instead of being greatly distorted in the middle ; the 

 inner margin is straight, in ^4. atkinsoni it is lobed towards the base, the lobed portion 

 beino; turned under ; the hindwincr is more elonorated, the discoidal nervule is obsolete ; 

 in A. atkinsoni it is fairly well-developed ; lastly, the palpi diflfer considerably, the 

 third joint being entirely hidden beneath the long hairs of the second joint instead nf 

 being projected far beyond that joint. In Arnetta atkinsoni the male has the bases ot 

 the first and second median nervules of the hindwing much swollen, this character 

 being found also in the genera Gangara, Moore, and Paduka, Distant, but is absent 

 in the genus Itys. (de Niceville.)

Imago. — Male. Upperside, both wings dark vandyke-brown, suffused with pnrpl(\ 



especially on the costal and outer margins and the veins ; the cilia ochreous-grey. 



Foreiring with five .small semi-transparent white lustrous spots, two (the first of whicli 



is very minute) before the apex, and three discal, one geminated in the cell consisting 



of an anterior outwardly convex thin crcscentic and a posterior triangular portion, 



another about the same size behind and a little external to this between the first and 



second median nervules sub-crescentic in shape, with its convexity turned towards rlic 



base, and a third squarish external to and in front of, and rather less than half tlie 



size of, this again between the second and thu-d median nervules. Underside. Forr- 



wing lighter than above, the translucent spots as on the upperside ; with an indistinct 



sub-marginal band of spots darker than the ground ; a dark anteciliary line ; the cilia 



obsoletely intersected at the veins with dark; and an indistinct whitey-brown spot 



touching the first median nervule and the satiny patch extending from the base nearly 



to the outer angle and from the interno-median fold to the inner margin of the wing, 



which bears a conspicuous fringe of slate-grey setse in part projecting straight liark- 



wards and outwards from the edge and in part turned up so as to lie spread out 



fan-wise over the satiny-ashy patch. Hindwing darker and more suffused with purple 



than the forewing, with a dai-k anteciliary line, but even less distinctly intersected 



cilia ; with some dark mottling indistinctly arranged in three bands, one sub-basal and
