Habitat. — England, Europe, and North America. 



Specimens in National Museum and Coll. Ashmead. 



This European species is now evidently widely distributed in" North 

 America, and has probably been imported with its Syrjjhid host, Uris- 

 talis tenax. I have specimens from Long Island and Albany, N. Y. ; 

 Ottawa, Canada; Arlington, Ya.; VYashington, D. C; and Marquette, 

 Mich. It is recorded by Kirchner (Cat. Hym. Europse, p. 204) as para- 

 sitic on Uristalis tcnax, and I have seen specimens in the Berlin Mu- 

 seum reared from this insect, while Mr. L. O. Howard informs me 

 Dr. Liutuer has reared it from this same Diptenm at Albany, N. Y.
