THE GENOTYPES OF SAWFLIES AND WOODWASPS. 73 



The plan in the following list is to give the generic name first, the 

 name of the author second, the original reference tliird, the type 

 species fourth, the authority for the type fifth. In case the genus 

 was monobasic, an asterisk is placed after the type species; in case 

 the genotype was originally designated, the word "designated" is 

 placed in parentheses; in case the genus was not monobasic and no 

 genotype has been designated, the type has been chosen and no au- 

 thority is given (see Amauronematus Konow). Certain apparent syn- 

 onymy, as in the case of isogenotypic genera, is also given. All such 

 synonymy has been verified, and synonymy not verified is not given. 



The list of genera is believed to be complete, in as far as publications 

 have been received in Wasliington, D. C, up to January 1, 1911. 

 All the new generic names proposed in this paper are included in the 

 alphabetical catalogue with the reference, "see p. — ."
