endeavor to get through all the diurnal lepidoptera as speedily as 

 possible. We shall frequently include species which inhabit New 

 York and other Northern States, and which are likely to occur in 

 Canada. As we know of no work exclusively devoted to Canadian 

 species, we are compelled to adopt this course, as otherwise many 

 Butterflies would be omitted, which doubtless inhabit those por- 

 tions of this country with which we are unacquainted. We liopc 

 our correspondents will be able to set at rest any doubts respecting 

 some, if not all such species, by sending us specimens, and all 

 necessary information regarding them.
