 laevis (Gravenhorst). Que., Maine, N. H., N. W. T., Tex.?, Alaska; Europe. Aubert (1969, 1972) 



stated that D. laevifrous (Thomson) is a species distinct from laevis, but gave no 



indication that he had ever studied the holotype of laevis.

Revision: Kerrich, 1966. Entomologist 99: 44-46 (European spp.). 

 maculicoxis (Kriechbaumer). Que. s. to N. C, w. to Alta. and Calif.; Europe. Ecology: In North 

 America the species has been associated with Rhyssa howdenorum Townes and Rkyssa 

 persuasoria (L.) and is presumably cleptoparasitic on them. Kerrich (1966) has shown 

 that Townes (1960) misidentified the holotype o{ Rhyssa approximator var. mficoxis 

 Kriechbaumer, and Kerrich palaced mficoxis as a synonym of alpestris (Holmgren), a 

 species which does not occur in North America. 

 Rhyssa approximator var. mactilicoxis Kriechbaumer, 1889. Ent. Nachr. 15: 318. 9. 

 Kerrich (1966) incorrectly considered the name maculicoxis invalid because it was 

 originally proposed as a varietal name that was "used in an aberrational sense."
