XXI. On some new species of African Picrimv in the col- 

 lection of the British Museum, with notes an seasonal 

 forms of Belenois. By ARTHUR G. BUTLER, 

 Ph.D., F.L.S., &c. 



[Read November 16th, 1898.] 



WHILST arranging the Pierinse 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. n. 



< . 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. aylria} ; 

 the secondaries also with the costal area at base bright lemon yellow 

 instead of orange. Expanse, 50 61 millim. 



$ . 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. syhia. Expanse, 64 

 millim. 



Hob. ANGOLA and GOLD COAST (Mus. Brit.}. 



Phrissura narcissus, sp. n. 



9 . Primaries bright ochreous ; a grey subapical crescentic band ; 



veins pale buff, partly dividing a marginal series of black spots ;
