be very interesting, but can only be definitely established 

 through an examination of males from that region. In this con- 

 nection it may be useful to add that all specimens from eastern 

 North America which I have seen in collections identified either 

 as V. vulgaris or as V. germanica, belong, in my opinion, to 

 Vespa communis Saussure. 



5. Vespa (Vespula) acadica Sladen, Ottawa Naturalist, XXXII, 



1918, p. 72. 



Savonoski, 1 9, July, 1919. 



This interesting species is apparently the northern and 

 boreal representative of V. vidua Saussure. In the American 

 Museum of Natural History there are two workers from N. 

 Ontario, Canada and Boisdale, Cape Breton, which also belong 

 to acadica; but I have been unable to find a specimen of this 

 species from the United States in any of the collections examined 

 by me. 



6. Vespa (Pseudovespa) austriaca Panzer. 

 Savonoski, 1 9 , July, 1919. 



This specimen agrees perfectly with the females found near 

 New York in 1916 and which I have fully described in Bull. 

 Brooklyn Ent. Soc, XI, 1916, pp. 102-103. Since, I have seen 

 a female of this species from Mt. Hood, Oregon (G. P. Engel- 

 hardt Coll.) and a male from Beaver Mouth, Selkirk Mountains, 

 British Columbia (J. C. Bradley Coll.). The genitalia of this 

 male agree in every detail with those of a male from Thuringia, 

 identified as V. austriaca by Schmiedeknecht.
