These are all the species that I have seen from this locality. 

 Pier is Protodice was taken at Lachine, some years ago, by Dr. 

 Barnston. Argynnis Lellona was taken, last season (1874), by 

 Mr. Jack, on the south shore of the St. Lawrence opposite 

 Lachine, and will probably yet be found on the Island of Mont- 

 real ; and I think additions will be made to the Lycsenidae and 

 Hesperidge when these groups have been properly worked up. 



I have, with two or three exceptions, followed Mr. W. H. 

 Edwards's synopsis in this list, both in classification and nomen- 

 clature. 



I hope to soon give lists of the remaining families, and would 

 here gratefully acknowledge the assistance given me by those 

 friends who kindly allowed me to study and refer to their mate- 

 rial, amongst whom I would especially mention Messrs. Wm. 

 Couper, P. Kutzing, C. W. and G. B. Pearson. — The Canadian 

 Entomologist.
