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
