1891.] BUTTERFLIES FROM EASTERN AFRICA. 191 



Underside considerably different from that of M. rueppelli, the 

 hinder wing and the apex of the fore wing being ochreous, 

 each nervule being represented on the hind margin by a spot of 

 black ; the base of the fore wing with an oblique mark of bright 

 orange as on the upper surface, but this orange mark is extended 

 much further along the costal border and reaches beyond the limit 

 of the discoidal cell. 



Exp. 2|- inches. 



Hab. Kavirondo, Oct. 1889. 



6. Teracolus elgonensis, sp. u. (Plate XVI. fig. 6.) 



General colour greenish white, with a small black spot at the end 

 of the discoidal cell. The costal margin is narrowly edged with 

 black, which is much broader at the apex, and continues along 

 the hind margin, decreasing in width towards the submedian nervure, 

 where the black terminates. Near the apex, between the third 

 subcostal and first radial nervules, is an ovate spot of deep crimson 

 followed by two other spots smaller in size, the last being nearly obso- 

 lete. At the base near the inner margin is a slight shading of grey. 

 The hind wing is greenish white with no visible markings. 



Underside, fore wing white, with the costal margin, hind 

 margin, and apical portion pale yellow, the small black spot at the 

 end of the discoidal cell visible. 



Hind wing entirely pale yellow, the costal margin narrowly edged 

 with orange ; a small streak of black is very distinct at the end of 

 the cell ; from the end of the costa to the submedian nervure is a 

 half-circle of light brown spots between the nervules. 



Exp. 3 inches. 



Eab. Mount Elgon, Feb. 1890. 



7. Belenois margaritacea, sp. n. (Plate XVI. fig. 4.) 



Fore wing with more than the basal half pearly white, the apical 

 portion of the wing with the costal margin black, this black 

 extending to the posterior angle but becoming much narrower in 

 this direction. Some slight indications of subapical whitish 

 streaks. 



Hind wing pearly white with a bluish reflexion ; the hind margin 

 with a tolerably broad band of black indented by subterminal spots 

 of bluish white, becoming smaller and more longitudinal between 

 the first and second median nervules, and becoming obsolete above 

 the submedian nervure. 



Underside. Eore wing with the basal portion white, with a yellowish 

 tinge, inclining to pale orange near the extreme base ; costal margin 

 and apical portion of the wing black, inclining to bronzy black at 

 the apex and on the hind margin ; this leaves a subterminal band of 

 deeper black bordering the white area. 



Hind wing bronzy black, with a spot of orange -yellow before the 

 apex, and with a slight edging of yellow near the base of the costa ; 

 a slight indication of a paler subterminal shade of bronzy brown 

 along the hind margin.
