106 MR. R. TRIMEN ON BUTTERFLIES [Jan. 20, 



the underside, where the pale ochre-yellow tint is reduced to a mere 

 tinge of the pale greyish-brown ground. The other, although a 

 male, agrees with the female examples noted in my ' South-African 

 Butterflies' (iii. p. 358) — from Natal and Delagoa Bay — as having 

 the vitreous spots of the fore wing much reduced in size ; it also 

 has, to a greater extent, the sparse discal hoary scaling on the 

 upperside of both fore and hind wings which characterizes those 

 examples. From the occurrence of other examples of both sexes 

 recently on the Natal coast, I am disposed to think it not unlikely 

 that this supposed variety of P. motozi may prove to be a distinct 

 species.

cJ . Pale ochre-yellowish-brown, with conspicuous white vitreous 

 black-edged spots in fore wing, and a very broad median lohite band 

 {marked externally with blacJc spots) in hind wing ; cilia white, 

 interrupted at extremity of nervules with brown in fore wing and with 

 black in hind wing. Fore wing : terminal discocellular spot large, 

 more or less rounded ; spots in discal row nine, larger than usual, 

 all very distinct, arranged in three groups, viz. : two smallest, 

 united, next costa ; three somewhat larger, rounder, separate, form- 

 ing a curved row below and beyond first two ; and four below 

 discoidal cell, of which the uppermost (between 3rd and 2nd median 

 nervules) is separate and of moderate size, while the remaining three 

 (of which the uppermost, between 2nd and 1st median nervules, is 

 the largest on the wing) are more or less closely united in a slightly 

 oblique line beneath terminal discocellular spot. Hind wing : basal 

 area of a darker tint ; inner edge of broad white band well-defined, 

 almost straight, outer edge rather suffused with ground-colour on 

 nervules ; black spots very conspicuous, forming a roughly semi- 

 circular series of nine, of which the first is on the brown inner edge 

 of white band (between costal and subcostal nervules), but all the 

 rest, from costal to submedian nervure, a little within the outer 

 edge. Underside. — Paler, the ground-colour without ochre-yellow 

 tinge. Fore wing : edgings of vitreous spots very attenuated and 

 in parts obsolete ; some whitish scaling near base and along inner 

 margin. Hind wing : basal area greyish white except on costal 

 border ; white band extending rather further beyond black spots, 

 which are in five specimens rather smaller (especially the 3rd, 4th, 

 and 5th). 



Head and body of ground-colour above (the four terminal abdo- 

 minal segments with slender white half-rings) ; white beneath, in- 

 cluding palpi. Antennee black above, whitish beneath. 



This delicately tinted species clearh' belongs to the group named 

 Satarupa by Moore (Proc. Zool. Soc. 1865, p. 780), which is 

 characterized by the hind wings presenting on both surfaces a broad
