In these tables there is no separate account taken of the 
species of Sphina. is genus cannot be satisfactorily split up, 
as I am sure that the different divisions proposed (¢. g Tnnt- 
neria) have not sufficient or any real characters to sustain them. 
lie all of the divisions. But many of the species fall evidently 
under either the second or third group. W jeraru 
is evidently allied to the European species, Gordius and allies 
are probably of southern extraction, and in Hisa and Dolli 
we have probably forms of American origin. The genus 
Ider i 
to my first arrangement of the genera. We have neither Macro- 
glossa nor Acherontia ; the decisive element in our fauna does 
not come from the Old World. 
But on the whole the tables are probably approximately 
accurate, sufficiently so as to draw attention to the class of facts 
which a study of this interesting group offers, and in presenting 
them, in connection with a resumé of our knowledge as to the 
number of kinds of North American Sphingide, the writer asks 
the indulgence of the reader. They have been the result of a 
long-continued study of this group of insects, and are put forth 
to invite the attention of entomologists to the recording of 8 
subject which the late
