 Station); Oregon (Portland); Pennsylvania (Spring Brook); Quebec 

 (Cap Rouge, Hemmingford, and Norway Bay) ; Washington (Ashford, 

 Bellingham, Bothell, Index, San Juan Island, Seattle, Wiser Lake in 

 Whatcom Co., and Westport). 



The species has been taken in numbers from May until August, the 

 largest number of captures being in July. Especially early and late 

 records include April 17 and 20 at Bellingham and Seattle, Wash., 

 respectively, and October 2 and 3, at Lethbridge, Alta., and San 

 Mateo, Calif., respectively. 



Hosts: Salt (1931) gives a comprehensive account of the species 

 as a parasite of Cephus pygmaeus (Linnaeus) in England, and Holmes 

 (1953) records it from Cephus ductus Norton, from Lethbridge, Alta. 

 Reared material at hand includes two females reared from Cephus 

 pygmaeus, at Joy, N. Y., Aug. 28, 1924, and Darien, N. Y., Aug. 29, 

 1924; a male and female reared from wheat stems at Chatterton, 

 Ont., July 30, 1953, by C. C. Loan; and a female reared from an oat 

 stem at Grand Pre, N. S., July 26, 1957. 



The species, which is also Palearctic, has a transcontinental dis- 

 tribution in the Transition zone in North America.
