Hope Valley in Alpine Co., Leevining, Placerville, Smoky Jack Camp 

 in Yosemite Park, and Snowline Camp in El Dorado Co.); Colorado 

 (Williams Canyon in El Paso Co.) ; Maine (Bar Harbor) ; Michigan 

 (Ann Arbor, Douglas Lake, and Whitefish Point in Chippewa Co.) ; 

 New York (Allegany State Park, Erie Co., and Frontenac Point on 

 Cayuga Lake) ; Ontario (Toronto) ; Quebec (Aylmer and Laniel) ; 

 and Tennessee (Great Smoky Mountains National Park). We also 

 have studied a number of females from southern Germany. 



The above American specimens were all collected from June 10 to 

 July 21, except for a male taken May 25 near Alpine, Ariz. 



Biological data on pin labels are as follows: 9, ovipositing in Pinus 

 ponderosa containing Melanophila, Placerville, Calif., F. B. Herbert. 

 9, reared from Abies concolor, El Paso Co., Colo., June 10, 1904, 

 H. B. Kirk. 69, parasitic on siricid in Abies concolor, Williams 

 Canyon, Colo., June 12, 1916, George Hofer. cf, 9, parasitic on borer 

 in Larix trunk, Bar Harbor, Maine, 1944, A. E. Brower. 29, "Larix," 

 Erie Co., N. Y., Blackman. 9, reared from Picea mariana infested by 

 Monochamus sp. and Tetropium cinnamopterum, Laniel, Que., June 10, 

 1933. 9, reared from Abies, Queens Park, Aylmer, Que., June 27, 

 1921, F. C. Craighead. 



This species is transcontinental in the Canadian zone and occurs 

 also in Europe. It parasitizes siricids and perhaps also Coleoptera 

 boring in conifer trunks. Adults occur mostly in June and July.

This tribe includes seven genera, which have recently been revised 

 by Townes (1957, Proc. Ent. Soc. Washington, vol. 59, pp. 16-20). 

 The three Nearctic genera are treated below. The revision of the
