GENERA ORIGINALLY PROPOSED IN CHALCIDOIDEA, BUT SUBSE- 

 QUENTLY TRANSFERRED. 



The following generic names, originally described in the Chal- 

 cidoidea, have been transferred to the Serplioidea by Ashmead, 1904, 

 p. 364: 



Agonophorus Dahlboni. 



Macrostigma Rondani. 



Trichasius Provancher. 



DEFINITIONS OF TERMS. 



AuTOBASic. — If a new generic name is proposed as a substitute for 

 another name because of preoccupation or for any other reason, the 

 new generic name automatically takes the same type as the genus 

 which it is to replace and the type fixation is said to be autobasic. 



Monobasic. — AVhen a genus is described with but one originally 

 included species, that species becomes the genotype and the genus is 

 said to be monobasic. 



Original designation. — When a genus is described with one or 

 more originally included species and the author of the genus in the 

 original publication designates one of these species as genotype the 

 fixation is called original or first designation. 



Present designation. — When a genus without a fixed type has one 

 designated for it in this paper the fixation is by present designation. 



Monobasic through subsequent reference. — When a genus is 

 described wnthout originally included species and a subsequent refer- 

 ence, either by the author of the genus or a different author, for the 

 first time definitely assigns a single species to it, that species becomes 

 the type and the fixation is said to be monobasic through subsequent 

 reference. 



By DESIGNATION OF. — When a genus, without a fixed type, has one 

 correctly chosen for it subsequent to the original publication the 

 fixation is "by designation of" the author so choosing. 



IsoGENOTYPic. — Two genera are isogenotypic when the same species 

 has correctly been named as type of each. 



Isogenotypic through synonymy of genotypes. — Two genera 

 are isogenotypic through synonymy when their genotypes are syn- 

 onymous. 



ARRANGEMENT OF CATALOGUE. 



Generic names are listed alphabetically and the scheme of arrange- 

 ment under each name is as follows: 



Generic name and author. Isogenotypic synonymy, if any. Ref- 

 erence to original description, and in cases where no species were 

 originally included the original reference is immediately followed 

 by the first reference in which species were included. Number of
