forms of Belenois. By Artruur G. BUTLER,

[Read November 16th, 1898.] 
WHILST arranging the Pierine of the genus Phrissura, I 
discovered three males of a species which is certainly 
undescribed, mixed up with the series of P. sylvia (the 
dry-season form of P. eudoxia), and in the Hewitson col- 
lection I discovered the female of the same species I now 
describe. 
Phrissura perlucens, sp. 0. 
¢. Above nearly resembling P. sylvia, but with the inner edging 
of the black outer border of primaries more blurred, less distinctly 
dentate-sinuate, the basal patch of lemon yellow without the least 
tinge of orange; on the undersurface the border far more distinct 
than in P. sylvia, irrorated with dark brown, yellowish externally ; 
the base bright lemon yellow as above (not orange, as in P. sylvia) ; 
the secondaries also with the costal area at base bright lemon yellow 
instead of orange. Expanse, 50—61 millim. 
Q. Similar in pattern to the female of P. sylvia, but with the 
ground-colouring of all the wings above pure white ; the border of 
primaries and marginal spots of secondaries rather broader than in 
P, sylvia; primaries below bright lemon yellow at base, slightly 
washed with saffron on costa; apical area irrorated with grey- 
brownish and with an oblique subapical stripe of the same colour ; 
secondaries with the base of costal area golden yellow, slightly more 
saffron on costal margin : no trace of the ochreous bordering common 
to the undersurface of all the wings in P. sylvia, Expanse, 64 
millim. 
Hab. ANGOLA and GoLp Coast (Mus, Brit.). 
Phrissura narcissus, sp. v. 
Q. Primaries bright ochreous ; a grey subapical crescentie band ; 
veins pale buff, partly dividing a marginal series of black spots ;
