THE GENOTYPES OP SAWFLIES AND WOODWASPS. 103 



sions were corrected by Doctor Ashmead, and it is most unfortunate 

 that these were not left in condition in which they could be published. 



In the tables of the genera of Tenthredinoidea many genera were 

 described as new, and some of these were based on species hitherto 

 undescribed. The characters given in the tables are sufficient to 

 satisfy the technical requirements, so the generic and specific names 

 should date from their publication in the tables. Various writers 

 have considered the characters given in the tables to be of no value, 

 and in some cases this is correct. On this basis they have sunk into 

 the synonymy genera which have as good standing as many which 

 they recognize. 



In the present paper the new genera founded on new species in 

 the tables in the Canadian Entomologist for 1898 are characterized 

 more completely, and a list of all the genera described, with the 

 synonymy, as far as it has been determined, is given. Unless other- 

 wise stated the types have been studied, and the conclusions based 

 on these studies.
