4 HYMENOPTERA OF AMERICA NORTH OF MEXICO 



Hymenoptera of America North of 

 Mexico-Synoptic Catalog 



(Agriculture Monograph No. 2) 

 SECOND SUPPLEMENT 



INTRODUCTION 



The "Hymenoptera of America North of Mexico — Synoptic 

 Catalog" was published on July 11, 1951. It contained references 

 to the literature published through 1949, and to a few papers that 

 appeared during 1950. The First Supplement to this catalog was 

 published on October 8, 1958. It covered the literature that ap- 

 peared from 1950-1951 through 1956. The Second Supplement, 

 which is presented herewith, includes the literature published 

 from 1957 through 1963, and in some sections, most of the papers 

 that appeared during 1964. 



In general, this Second Supplement to the "Hymenoptera of 

 America North of Mexico — Synoptic Catalog" preserves the form 

 of the First Supplement. New supergeneric, generic, subgeneric, 

 and trivial names are starred. Abbreviations and symbols agree 

 with those used in the Catalog and First Supplement. 



Additions to distribution, hosts, or prey, or corrections to 

 entries in the Catalog or First Supplement are made following the 

 citation to the generic, subgeneric, or trivial name as it appears in 

 the Catalog or First Supplement. Additional references to papers 

 on biology, distribution, or taxonomy are made in the same way. 

 In the center headings the first page reference is to the Catalog, 

 followed by a reference to the First Supplement, if the latter is 

 necessary. 



Generic transfers are shown as follows: 



Genus CEPHALGIA Panzer, pp. 9-10, Sup. 1, p. 8 

 apicalis (Westwood). Transf. to Acantholyda subg. Acantholyda A. Costa. 



ACANTHOLYDA subgenus ACANTHOLYDA A. Costa 

 ( = Acan/hofyda A. Costa of Catalog, in part, pp. 7—9) 



apicalis (Westwood). Transf. from Cephalcia Panzer, p. 9 (teste Middle- 

 kauff, 1958, loc. cit. supra, p. 77). 



When a species is transferred to a genus or subgenus different 

 from the one in which it appears in the Catalog or First Supple- 

 ment, all synonyms and other information under it are also trans- 

 ferred, unless indicated otherwise. 



New synonymy is shown: 



modesta MacGillivray. Syn. of pini Rohwer.
