806 Hymenoptera in America North of Mexico 



Dichalysis Foerster, 1856. Hym. Stud., v. 2, pp. 52, 56. N. name, unnecessarily proposed 

 for Psilocera. 



Psilocera was twice renamed by authors who thought the name was preoccupied by 

 Psilocerus Ruthe, 1831. Graham, 1969 (Brit. Mus. (Nat. Hist.) Ent., Bui. Sup. 16: 463) is not sure 

 the North American species referred to Psilocera really belong to it.

Genus CATOLACCUS Thomson 



Pteromalus subg. Catolaccus Thomson, 1878. Hym. Scand., v. 5, pp. 146, 152. 



Type-species: Catolaccus cavigena Thomson. Monotypic. 

 Merisoides Masi, 1911. Lab. Zool. Gen. e Agr. Portici, Bol. 5: 141. 



Type-species: Merisoides crassiceps Masi. Monotypic. 



The European species cavigena Thomson and crassiceps Masi are generally accepted to be 

 synonyms of ater Ratzeburg. Graham, 1969 (Brit. Mus. (Nat. Hist.) Ent., Bui. Sup. 16: 467) is not, 

 however, entirely satisfied that this is true.
