Tingrdide. 121 
PIESMINA. 
PIESMA, Lep. 
(Zosmenus, Lap.). 
A genus whose position is somewhat doubtful, as it wants 
several of the more pronounced characters of the Tingidide, 
and yet differs from the Lygqeide in others ; it makes a sort 
of link between these families, and as it is generally classed 
with the Tingidide I have left it there. It may be known 
from all the other genera by its exposed scutellum, its 
distinct clavus and membrane, its ocelli,and the form of the 
cheeks, which are produced in front into distinct horn-like 
processes. 
There are fifteen species given by Puton, but many 
of them are very closely allied, and some may possibly not 
retain their specific value.
