 the Sawflies 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, 1911, certain corrections and 

 additions are necessary. 



A careful study of Panzer's "Faunae Insectorum Germanicse 

 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.
