[Received May 22, 1871.] My principal object in the present paper is to refer the species this very difficult group to the genera into which I separated it in my " Revision of the Genera of the Subfamily Pierinee'''' (Cist. Ent. iii. pp. 33-58). I shall not, therefore, increase the difficulty of determining the already numerous and nearly allied species by describing all the unnamed forms at my disposal, but shall rather strive to lighten the labours of my fellow-workers by clearing up, to the best of my ability, the somewhat confused synonymy already existing. As one or two of the species of Elodina have been confounded by some Lepidopterists with Terias, I shall introduce that little genus into the present paper. Genus 1. ELODINA, Felder, Reise Nov.
