Larva with three anterior pairs and one posterior pair of fleshy 

 filaments. 



Type C. core, Cramer. 



Note. Cramer's P. core has hitherto been considered the same 

 species as that described by Fabricius (Ent. Syst. iii. p. 41) under 

 the name of eorus and cited under that name in his genus Euplosa 

 (Illiger's Mag. vi. p. 280). 



These two names, however, refer to totally distinct insects, each 

 belonging to a different section of this subfamily of butterflies '. 



From the ftict of these two names having been thus considered, 

 by modern authors, to represent the same species, several errors 

 have resulted in determining tlie types in certain of the genera. 



These errors are now, it is hoped, satisfactorily worked out in the pre- 

 sent memoir, and the several species assigned to their proper genera.

 recurved across the wing and sharply defined, the third and fourth 

 upper spots of a larger oval shape, the lower somewhat smaller ; 

 a minute spot on the costa above end of the cell, and another
