Intelligencer, 



About one hundred of the larvae 

 of this genus are known, including 

 those of several species which, being 

 yet undescribed, I have not enume- 

 rated in the foregoing list. These, 

 however, will be found indicated 

 under their respective food plants. 



It will be noticed, if the following 

 list of food-plants be compared with 

 that given in the 6th volume of this 

 work of the plants fed on by larvae 

 of the genus Depressaria, that the 

 order Umbelliferce, which feeds half 

 the known larvae of that genus, is 

 not patronised by any larva of the 

 genus Gelechia; that the Composite, 

 which support 14 Depressarice, only 

 nourish 10 Gelechice (amongst which 

 are some of our latest discoveries) ; 

 that the Leguminosce, which only 

 afford nourishment to 4 Depressarice, 

 are patronised by 16 of the present 

 genus, and the Caryophyllacece, which 

 nourish no species of Depressaria, 

 are already known to harbour 14 

 larvae of the genus Gelechia. 



On connait deja les chenilles a, 

 peu pres d'une centaine des especes 

 de ce genre, et meme celles de quel- 

 ques especes, qui n'ont jamais ete 

 decrites, et qui ne se trouvent pas 

 dans la liste que je viens de donner. 

 Ces chenilles cependant seront in- 

 diquees sous leurs plantes nourri- 

 cieres. 



Si nous comparons la liste des 

 plantes affectionnees par ces chenilles 

 avec la liste dans le sixieme volume 

 de cet ouvrage des plantes qui 

 nourrissent les chenilles du genre 

 Depressaria, nous remarquerons que 

 l'ordre des Ombelliferes, qui nour- 

 rit la moitie des chenilles connues 

 de Depressaria, ne nourrit aucune 

 chenille du genre Gelechia ; les 

 Composees, qui nourrissent 14 De- 

 pressarice, ne sont mangees que 

 par dix Gelechice (parmi lesquelles 

 se trouvent quelques-unes de nos 

 decouvertes les plus recentes) ; 

 tandisque les Leguminosees, qui ne 

 servent a nourrir que 4 Depressarice, 

 nourrissent 16 des especes du genre 

 dont nous traitons, et les Caryophyl- 

 lacees, qui ne nourrissent aucune 

 espece de Depressaria, sont deja 

 connues comme plantes nourricieres 

 pour 14 chenilles du genre Gelechia.
