In this paper, we present the first part of a revisional study of North American spiders belonging to the group Ageleneae. It deals with the genera Agelenopsis of Giebel and Calilena, Ritalena and Tortolena, newly proposed for groups of western and southern species. In the case of Agelenopsis, both sexes are described for all species excepting texana and aleenae which are at present known from the males only. Our knowledge of the second genus is less complete and various gaps remain to be filled. In the second paper, which it is hoped will follow at an early date, the remaining genera of the Ageleneae as represented in North America will be covered in a similar manner.
