The Pierimae have been given family 1ank by some authors but they 
certainly can not be placed on an equality with the Hesperidae and given 
the same family value. The tibial epiphysis is a small, concavo convex 
lappet like organ, attached near to or above the middle of the inner side 
of the tibia, and covering a small excavation. It is universally present in 
the Vo. fuidae, but is only found in the Papelionidae and Hesperidae in the 
Rhopalocera. Westwood and others call it a spur, but it is not at all 
s.:iuilar to the spurs of the median and posterior tibia. Speyer in Edwards 
catalogue, calls it the tibial epiphysis and I adopt the term. The Pap:-
