The other, although a male, agrees with the female examples noted in m y ' 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. 123. PTERYGOSPIDEA JAMESONI. (Plate IX. fig. 25.) Antigonus jamesoni, E. M . Sharpe, Ann. & Mag. Nat. Hist. 6th ser. vol. vi. p. 348 (Oct. 1890). Allied to the North-Indian P. bhagava (Moore). Exp. al. 1 in. 5-7 lin. 8 . Pale ochre-yellowish-brown, with conspicuous white vitreous black-edged spots in fore wing, and a very broad median white band (marked externally with black 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, forming 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 ratber suffused with ground-colour on nervules; black spots very conspicuous, forming a roughly semicircular 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 abdominal segments with slender white half-rings) ; white beneath, including palpi. Antennae black above, whitish beneath. This delicately tinted species clearly 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 |
