The identity of this species is at British Museum, nor, so far as is 
present unknown, and from Walker’s known, in any other museum in 
extremely brief description it 
can not be recognized as any 
one of the North American 
species discussed in this paper. 
It is highly probable that all 
of the older American distribu¬ 
tion records for this species, 
possibly excepting the original 
one, refer to what we now 
know as Orthezia solidaginis 
Sanders. These records in¬ 
clude Lower Canada, New 
York, Ohio, and Iowa. The 
species was originally de¬ 
scribed from “ North America.” 
In recent correspondence Mr. Great Britain. Since this type ap- 
Frederick Laing of the Natural parently no longer exists, and since the 
species can not be placed from 
the original description, it seems 
best to set it aside as a wholly 
unrecognizable species and to 
eliminate it from further con¬ 
sideration in connection with 
the genus Orthezia .
