PREFACE. 



The present volume contains the 

 histories of fifteen species of the 

 genus Gracilaria, and nine spe- 

 cies of the genus Ornix. 



Its appearance has been re- 

 tarded owing to the delay in 

 meeting with the larva of Gra- 

 cilaria Imperialella ; for, having 

 originally contemplated repre- 

 senting the transformations of 

 that species on the fifth Graci- 

 laria Plate, I was unwilling to 

 abandon that idea, and preferred 

 waiting till I could carry out my 

 project. I imagine few will refer 

 to that Plate without beins; of 

 opinion that the insect was well 

 worthy of a little delay. 



The next two volumes will 

 each contain twenty-four species 

 of the genus Gelechia. 



Many of the drawings in the 

 present volume are by Miss 

 Wing, some of whose larvae are 

 most life-like. I may particularly

Ce volume contient les histoires 

 de quinze especes du genre Gra- 

 cilaria, et de neuf especes du 

 genre Ornix. 



II aurait paru plus tot si ce ne 

 fut qu'on avait tarde de trouver 

 la chenille de la Gracilaria Im- 

 perialella, dont j'avais designe 

 representer les transformations 

 sur la cinquieme Table, idee que 

 je ne voulais pas abandonner, et 

 j'aimais mieux retarder un peu 

 la publication du volume. Je 

 congois que ceux qui regardent 

 la cinquieme Table partageront 

 avec moi 1' idee, que cette espece 

 a ete digne de tant d' attention. 



Les deux prochains volumes 

 contiendront chacun vingt-quatre 

 especes du genre Gelechia. 



Plusieurs des dessins dans ce 

 volume furent faits par Made- 

 moiselle Wing ; quelques-unes des 

 chenilles qu'elle a peintes parais-
