Excerpt from A Revision of the Moths of the Subfamily Prodoxinae (Lepidoptera, Incurvariidae) In 1892, C. V. Riley presented a paper in the third annual report of the Missouri Botanical Garden which summarized all that was then known of the biology and classification of yucca moths. Since that time, surprisingly little interest has been shown in this group of Lepidoptera; consequently, Riley's paper has remained the only comprehensive reference for the group. Unfortunately, this work, as well as several other classic studies of his, are no longer readily available to many biologists. Also, considerable information on general biology and systematics has appeared in recent years which has decreased the scientific merit of earlier efforts. Because of Riley's meticulous manner of observation, however, his biological studies probably will continue to be valuable sources for information regard ing these insects.
