from The Century Dictionary and Cyclopedia
- A tribe of hesperian lepidopterous insects combining in some respects the characters both of moths and of butterflies, but justly regarded as having most affinities with the latter. They are characterized by a small head, a very large abdomen, unarmed front tibiæ, and very small spurs of the middle and hind tibiæ. The tribe is typified by the yucca-borer, Megathymus yuccæ, formerly Castnia yuccæ, and includes the genus Ægiale.
