Specimens possessing the characters given for onusta on page 301 show differences in the colour of the superior 
surface of the frons that seem possibly due to age. The males from Key West, Round Mt., Jalapa, and 
Teapa, the females from Round Mt., Guadalajara, Teapa, and Sardinero have the frons yellowish or 
luteous with no metallic or red colouring, although the Round Mt. male and one or two of the females 
from more than one locality have a narrow obscure transverse stripe in front of the eyes. Males from 
Texas (exact locality not known), Wilson’s Lake, Altamira, San Luis Potosi, Guadalajara, Amula, and 
Tuxtla have the frons bright red, but in some of these a transverse metallic-violet or blue stripe in front 
of the ocelli and eyes exists. Finally, in the males from Florida (exact locality not known), Mesilla, and 
San José del Cabo the upper surface is more or less metallic-violet ; these last examples have the colours 
of the body generally darker, and are consequently presumably older. In the oldest females before me, 
those from Tepic and Cuernavaca, the upper surface of the frons is yellow with a narrow transverse 
metallic stripe in front of the ocelli and eyes. Somewhat similar age-changes in the colour of the frons 
appear to be indicated by the accessible material of 7. carolina, the nearest ally of onusta. 
The size and shape of the basal brown marking of the hind wings vary much, especially in the females, 
where it is smaller, more indented on both outer and inner edges, and less densely veined than in the 
males. In the males it may extend out to the fourth antecubital and almost on the level thereof across 
the entire width of the wing with but slight indentations on its distal margin, and with the deepest part
