Ahaton Harris ; Very common ; end of June and July. 



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

 protodice was taken at Lachine some years ago by Dr. Barnston. Argynnis 

 bcllona was taken last season (1874) by Mr. R. Jack, on the south shore 

 of the St. Lawrence, opposite Lachine, and probably will yet be found on 

 the Island of Montreal, and I think additions will be made to the 

 Lycaenidre and Hesperidre 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 nomenclature. 



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 material, amongst whom I 

 would especially mention Messrs. Wm. Couper, P. Knetzing, C. W. and 

 G. B. Pearson.
