 Protepeolus singularis Linsley and Michener, Rhipiphorus sexdens Linsley and 

 MacSwain, Spamoplius brevicomis Loew. Pollen: Collects pollen from flowers of 

 Sphaeralcea and Kallstroemia grandiflora. Diadasia olivacea (Cresson, 1878. Acad. 

 Nat. Sci., Phila., Proc. 30: 216), described from Mexico, may be a senior synonym 

 according to Timberlake (1957. hi Linsley and MacSwain, Wasmann Jour. Biol. 15:215); 

 however, Krombein (1967. U. S. Dept. Agr., Agr. Monog. 2, suppl. 2: 502) deletes the 

 species from the fauna of America north of Mexico. The type of D. olivacea was 

 collected by Sumichrast who made his collections of Hymenoptera in the environs of 

 Orizaba and Cordoba (see Cresson, 1868. Amer. Ent. Soc, Trans. 2: 1). This is well to 

 the south of the known southernmost occurrence (Zacatecas) of D. ochracea. The types 

 of D. olivacea and D. ochracea, both males, must be reexamined in order to determine 

 the validity of the proposed synonymy.
