It seems to me probable that Augusta will be found in Utah and 

 Arizona, perhaps also in Nevada. 



TENTHREDINIDyE COLLECTED AT OTTAWA, 1889. 



BY W. HAGUE HARRINGTON, OTTAWA. 



The past season was not a favorable one for the collection of Hymen- 

 optera. The early spring was very fine and warm, but vvas followed by 

 prolonged spells of cool and rainy weather, which not only made collect- 

 ing difficult, but appeared to destroy many of the insects. This will be 

 seen by the following list, in which a large proportion of the species are 

 represented by single specimens. It contains about eighty species, or 

 nearly two-thirds of those that have so far been taken in this locality. 



Few of the species were at all common, the most abundant and de- 

 structive being N. Erichsonii Hartig., which we now find wherever there 

 are larches, and by whose larvfe these trees are defoliated and injured. 

 N. Ribesii Scop, (ventricosics Hartig.), the gooseberry saw-fly, and H. 

 niaculatus Norton, the strawberry saw-fly, were also numerous. Or\ the 

 other hand several of the species, especially of Macrophya and Tenthredo, 

 which are usually common in midsummer, were not observed, and there 

 was a noticeable scarcity of larvje.
