given him over the collection of the British Museum; to Dr. Boisduval, to Mr. 
Bates, and to Mr. Wallace, whose collections he has had access to as freely as if they 
were his own. 
CORRECTIONS. 
Pieris Eliada is the male of Cramer’s P. Liberia. 
Pieris Cycinna has been incorrectly printed P. Concinna in the description. 
Cycinna is the name by which the author wishes it to be known. 
Leptalis Antherize, of Boisduval, is L. Fortunata of Lucas (Annals Soc. 
Entom., 3rd Series, Vol. II., Plate 3.) 
Messaras Maonites is P. Lampetia of Cramer, Plate 349. 
N.B.—An Index is given, by which the binder will be enabled to arrange the 
Plates, as in the “ Genera of Diurnal Lepidoptera.” 
A second Index, alphabetically arranged, is given for the benefit of those who 
will take the trouble to number the Plates (from 1 to 60) and the letterpress (from 
1 to 120), after the book has been arranged by the first Index. 
N.B.—On append un Index par lequel le reliewr peut arranger les planches de 
la méme maniére qu’en ‘“‘ Genera of Diurnal Lepidoptera.” 
On append un second Index, arrangé alphabétiquement, pour servir a ceux qui 
veulent mettre les nombres aux planches (1 @ 60), et aussi au texte (1 a 120), apres 
qu’on aura arrangé le livre par l’aide du premier Index.
