This siDecies is a close ally of Charlonia, but the 

 whitish ? at once separates it, together with the very- 

 large discoidal spot and apical patch ; in the c? also 

 these two latter characters are decidedly larger than in 

 Charlonia, and the under surface of the hind wings is 

 often quite yellow, and when irrorated with grey is 

 never nearly as dark as in Donzel's insect. 



All the fourteen examples in the National Collection 

 were sent from the same neighbourhood, viz., Campbell- 

 pore, Attack Bridge, Akhor, and Khairabad, the earliest 

 specimen being labelled April 18th, 1886, and the latest 

 June 27th, 1886. 



The whitish ? is of great importance in our study of 

 this small group, in pointing out which of the two 

 forms, the white or the yellow, is in all probability the 

 ancestral species. 



Penia, Frr. 

 This species is — of the white group — the most nearly allied to 

 Charlonia, It is of a whitish colour, slightly tinged with pale 

 sulphur. The discoidal spot is brown, and in shape is a regular 

 quadrangle. The apical patch is greyish brown, deeply and 

 obtusely angled, extending fully three-quarters down the posterior 

 margin ; the spotted transverse band is angled in like manner. 

 The hind wings are more sulphurous, and exhibit the dark under 

 side through. Both wings are slightly greyish at the base. Costa 

 pink. Fringes greyish at apex, tinged with pink at anal angle. 

 Beneath the fore wings are whitish, tinged with sulphur on the 

 costal half, with the discoidal spot smaller, scarcely extending 

 beyond the costal margin of the cell. The apical patch is pale 

 greenish yellow, closely and finely irrorated with grey ; the costa 

 and fringes pinkish, the former very lightly dotted within the 

 apical area. The hind wings are yellowish green, finely irrorated 

 with pale grey ; the central whitish dot is small, sometimes rather 

 indistinct ; the posterior margin is slightly spotted ; and there is 

 scarcely more than a trace of the two spots between the central 

 spot and the anal angle. 



This species was first described by Freyer in his 

 *Neue Beitrage,' vi., p. 149, pi. 574, from a single 

 broken specimen without name or locality ; it was sub- 

 sequently found by Staudinger at Malatia, and by 

 Christoph in N. Persia and Turkestan, and I have 

 specimens from Krasnovodsk, on the Cas^Dian ; so that 

 it^probably ranges all through Northern Asia Minor and
