 the Sawfiies and Woodwasps, or the Super- 

 family Tenthredinoidea ^^ (Hymen.). 



By S. a. Rohwer, Bureau of Entomology, U. S. Department 

 of Agriculture, Washington, D. C. 



In the paper above quoted, published as Part 2, Technical 

 Series No. 20, Bureau of Entomology, United States Depart- 

 ment of Agriculture, March 4, 191 1, certain corrections and 

 additions are necessary. 



A careful study of Panzer's "Faunae Insectorum Germanicae 

 initia, oder Deutschlands Insecten gesammelt und herausgege- 

 ben," discloses the fact that some of the genera were described 

 earlier than they had heretofore been supposed to have been. 

 The results of this study make certain changes necessary. Cer- 

 tain generic names heretofore overlooked are also added. To 

 make the work complete, with the corrections, the species 

 should be added to the list of genotypes.
