shape, four on the disk and one above the second subcostal nervule : 

 the basal area somewhat browner and followed by a broad oblique 

 transverse band of yellowish white. 



Underside. Fore wing blackish, the transverse row of white 

 ovate spots distinctly marked, but becoming obsolete towards the 

 apex, where there is a distinct shade of ashy ; on the upper fore 

 margin of the discoidal cell is an indistinct spot of white. 



Hind wing light brown, darkening towards the apex and across 

 the disk ; the white spots not so distinct as on the upper surface, 

 the middle one of the five being obsolete ; between the second sub- 

 costal nervule and the radial nervule is an additional spot of white ; 

 basal area rufous, with a spot and streak of black above the sub- 

 costal nervure ; the discoidal cell with three black lines ; the rufous 

 base followed by a white band not so distinct as on the upperside of 

 the wing, and shaded with lilac under certain lights. 

 Exp. 4 inches. 



Hab. Between Sotik and Kavirondo, Sept. 1889. 

 The female is rather larger than the male, and is distinguished by 

 the patch of rufous ochre which takes the place of the white trans- 

 verse band of the male. There is a submarginal row of six white 

 spots on the hind wing, instead of five as in the male. Instead of 

 the band of longitudinal spots on the fore wing of the male, the 

 female has a submarginal row of rounded white spots differing in 

 size, five in number in a continuous series, confined to the disk, 

 absent between the fourth and fifth subcostal nervules and between 

 the latter and the first radial, but re-occurring between the third and 

 fourth subcostal nervules near the apex. There are three irregular 

 large white spots, one triangular on the upper margin of the dis- 

 coidal cell, another below the cell, ovate in shape, between the first 

 and second median nervules, and the third, a twin spot of irregular 

 shape, at the base of the fifth subcostal and first radial nervules. 

 Exp. 4\ inches. 

 Hab. Kikuyu, Sept. 1889. 



This species is also nearly allied to P. echerioides of Trimen (cf. 

 S. Afr. Butterfl. iii. p. 255), a species figured in the 'Transactions 

 of the Entomological Society' for 1868 (p. 72, pi. vi. figs. 1, 2). 



The position of the white spots on both wings is quite different, 

 and both spots and bands are white, not yellowish white as de- 

 scribed by Dr. Trimen. 



Subfam. Pierin^. 

 3. Mylothris wiNTONiANA, sp. n. (Plate XVI. fig. 2.) 



Female. Similar to thet female M. clarissa of Butler, and with a 

 yellowish hind wing as in that species, but with a very much broader 

 blackish border. 



Fore lui'tiff white, the basal area pinkish ; costal margin and an 

 oblique patch on the apex blackish, with four triangular spots on 

 the hind margin diminishing in size towards the posterior angle, the 

 spot at the end of the submedian nervure being very minute, those
