Ageronia ferona is grayish brown with rings and irregular lines 
of blue and black. There are a number of large and small white or 
light gray spots on the upper wings and a few on the lower pair. 
Ageronia ferona. Under side. 
The under side is much lighter, being almost white, with black 
markings. In very fresh and perfect specimens there is a pinkish 
tint with a satiny gloss over the whole surface beneath. 
In Ageronia fornax the upper side is colored much like the 
preceding insect, but the under side of the lower wings is light 
yellowish brown instead of white, and the large spots on the lower 
wiugs of Ageronia ferona have almost disappeared in this species. 
These two insects are occasionally taken in southern Texas. I know 
nothing of the early stages of these butterflies. 
To the genera of Hypolimnas belongs a number of good-sized 
handsome butterflies, generally dark in color, with purple and blue 
reflections and large white spots. These butterflies are confined 
almost wholly to the tropics of Asia, Africa and Oceanica and are 
frequently very abundant where they are found.
