The genus properly represents a subfamily of the Hesperiidce, which might be named the Megatbymince. The species represented in our cuts is Megathymus yuccce, Boisdu- val and Leconte. There are a number of other species of Megathymus that are found in our Southern States, principally in Texas and Arizona.
