 is, of course, quite unnecessary to repeat Kirby's description of this very

 description and admirable figures see Edwards' " Butterflies of North 

 America." vol. i. . part iv.] 



Personal. — Our esteemed friend, J. Pettit, Esq., has removed from 

 Grimsby, Ontario, to Buffalo, New York. Correspondents when writing 

 him will please bear in mind this change of address.
