Nelson, Auckland, fend Hawke’s Bay orchard districts, where it inflicts 
considerable damage on the foliage of apple and hawthorn. This Me 
is probably introduced from Australia; and must not be confused wi 
the well-known Empoasca mali (Le Baron) of America, which has not vet 
been introduced, and from which it differs not only structurally but also 
biologically, in that the results of its attack are rusty spots and patches 
on both sides of young and old leaves, instead of a curling of the younger 
leaves only, as in the American species. Its method of attack is very si 
to that of Typhlocyba (Empoa) -rosae (Linn.), which it resembles in some 
other respects, but from which it is quite distinct.
