LXVI. — On a neio African Pierine Butterfly of the Genus 

 Mylothris. By Arthur G. Butler, Ph.D. &c. 



The following species was received among the Old-World 

 Pierinae of the Godman and Salvin collection : — 



Mylothris primulina^ sp. n. 



Intermediate in character between M. asphodelus and 

 M. su^phurea from the Cameroons. 



(J. Above milk-white, the costa and the basal area of 

 primaries to end of cell bright cowslip-yellow, changing at 

 base and on the basal half of costa to bright cadmium-yellow ; 

 a smoky black apical patch, rather broader than in M. sul- 

 phurea, a large spot almost confluent with the latter at end of 

 second median branch, and a dot at end of first median branch 

 also black : secondaries bright cowslip-yellow at base, six 

 small black marginal spots. Body above greenish grey; 

 abdomen creamy white at the sides. Primaries below with 

 the cadmium-yellow at the base more extended and the apical 

 third of the wing traversed by greenish-yellow internervular 

 streaks ; apical patch only visible through the wing, but 

 seven black marginal spots : secondaries with the yellow at 

 base slightly more extended and the base of costa cadmium- 

 yellow, the outer border faintly tinted with primrose-yellow, 

 the black marginal spots rather larger than above. Body 

 below creamy white, the pectus with a feeble tint of primrose. 



Expanse of wings 58 millim. 



Ondo country, Lagos (.bir G. Carter). From Godman and 

 Salvin coll. 



We have two males of this very pretty species.
