INTRODUCTION 5 



pini Rohwer. 



Acantholyda modesta MacGillivray, 1923 (syn. by Middlekauff, 1958, loc. 

 cit. supra, p. 85). 



New status is shown as : 



johnsoni johnsoni Viereck, changed status. Reduced to subsp. rank (teste 

 Schuster, 1958, loc. cit. supra, p. 46). 



Generic or subgeneric transfer and a change in status may be 

 combined : 



SPHAEROPTHALMA subgenus PHOTOPSIS Blake 

 ( = Pho/ops/$ Blake of Catalog, in part, pp. 753—756) 



amphion (Fox), Transf. to Sphaeropthalnia subg. Photopsioides Schuster. 



♦SPHAEROPTHALMA subgenus PHOTOPSIOIDES Schuster 



amphion amphion (Fox), changed status. Transf. from Photopsis Blake, 

 p. 753 and reduced to subsp. rank (teste Schuster, 1958, loc. cit. 

 supra, p. 38). 



In the Aculeata, subgeneric assignment may be indicated by 

 a citation to the subgeneric name in parentheses following the 

 species entry: 



robustior Cockerell (JEumelissodes) 



In many entries here, the compiler of a particular section has 

 not agreed with the taxonomic placement or nomenclature used in 

 a publication by some other worker. This divergence of opinion is 

 expressed by citing the publication under the placement or usage 

 here considered to be preferable, followed by an indication of the 

 different placement or nomenclature in parentheses. For example: 



Genus EUPELMELLA Masi, p. 512 

 Nomenclature: Peck, 1963, loc. cit. supra, p. 492 (Macroneura) . 



In this Second Supplement the citations to the authorities for 

 some changes, additions, or deletions have been shortened in order 

 to save space. The references for new genera, subgenera, species, 

 subspecies, and varieties are cited in full throughout, but fre- 

 quently cited works may be referred to only by author, year, and 

 page following the first reference. For instance, in the Ichneu- 

 monidae, Townes and Townes, 1960. U. S. Natl. Mus. Bui. 216 

 (Pt. 2) : i-iv + 1-676 is, after its first citation, referred to as 

 Townes and Townes, 1960, followed by particular page references. 

 This has been done when this work is the authority for generic 

 transfers, deletions, changes in status, or synonymy. References 

 to discussions of biology, distribution, or taxonomy from this work 

 are cited in the same way. 



Elsewhere in this supplement frequently cited works may be 

 cited as loc. cit. supra, where such usage will save space without 

 producing ambiguity of reference. For instance, in the Symphyta, 

 Middlekauff, 1958. Calif. Univ. Pubs., Ent. 14: 51-174 is cited 

 completely under the Family PAMPHILIIDAE. Subsequently it is 

 referred to as Middlekauff, 1958, loc. cit. supra, with the page 

 reference, where it is the source for generic transfers, changes in 

 status, deletions, synonymy, or discussions of biology, distribu-
