The taxa studiedmainly by Ivie included his first completely eyelessspecies, which he named buwata and assigned to thestem genus Cicurina with special knowledge of themeaning of that genus. Inasmuch as buwata is anunknown taxon with unknown type locality comingfrom an area where numerous species are known tooccur, and not one can be singled out even as aplausible type species, the name buwata must bedropped as a nomina inquirienda of unknown status,and with it goes the unusable subgeneric name Cicurata.The subgenus Cicurella, with its well knowntype species, Cicurina microps Chamberlin and Ivie,has largely been used in a general but never in a genericsense by Ivie or following students. For thesake of editorial completeness the name buwata islisted at the end of the valid taxa of the genus.A list of the eyeless taxa follows: descriptions ofthe 50 valid species are given with information onstate and county localities of the United States andknown data on the Mexican records. In this paperthe generic name Cicurina covers all the taxa.Descriptions of the 50 eyeless taxa follows:TEXAS: Williamson County: browni, vibora,elliotti. new species, and buwata Chamberlin andIvie. Coryell County: coryelli, new species. Hays97
