Notes on and Descriptions of the Nearctic Wood- 

 wasps of the Genus Xiphydria Latreille (Hym.).

 partment of Agriculture, Washington, D. C. 



This paper, which is a contribution from the Branch of 

 Forest Insects, Bureau of Entomology, is based on a study of 

 the species of Xipliytlria in the collections of the National 

 Museum, the Academy of Natural Sciences of Philadelphia, 

 the Public Museum of Quebec and the British Museum. The 

 work is based in the greater part on the collections of the 

 National Museum but contains notes from the species in the 

 other collections. The type of the new species described and 

 the neotypes here designated are in the United States National 

 Museum. 



The North American species of Xifhytlria have been tab- 

 ulated by Konow (Syst. Zusam. Chalast., pp. 207-3 1 ; ::: ) , l )Ut - 

 inasmuch as that author did not have a large collection or ac- 

 cess to the types, there are some points which do not accord 

 with the facts. Harrington (Trans. Roy. Soc. Canada sec. 4, 

 iS()3) tabulates the Canadian species and MacGillivray (Bui. 

 22 Conn. Geol. Nat. Hist. Survey, 1917) tabulates the species 

 of the Northeastern States. None of these papers include all 

 of the species so it seems worth while to give a synopsis of 

 the North American species. The larvae of Xif>li\'i1ria are 

 wood borers and confine their attacks to dead <>r d\ in- branches
