Joubin, 1894, and C. macrosoma Goodrich, 1896. In 1924, Joiibin (p. 86) discussed rather vehemently the relationships of these species in an attempt to establish the priority of his species. A close ex- amination of the illustrations by all three authors and a study of the original descriptions lends much credence to his statements. I, also, believe that there is a strong possibihty that imperator and macrosoma are synonyms of pideti, but because I have had no opportunity to examine any of the types, a definite statement cannot be made at this time. If the three species are synonym-ous, the distribution given below would be amended to include records from the Atlantic Ocean. Distribution.—At present this species is Imown from Japan 635805—62 10
