Notes. Females of O . aff. trevoris can be recognized by the following combination of characters: clypeal margin with small triangular notch medially, clypeal setae brown, mandibular carinae parallel and scopa dark brown (M. Arduser, unpublished data). Males would run to couplet 27 in Mitchell (1962) , being similar to both O. collinsiae Robertson and especially O. subarctica (see above). The species was compared to O . inurbana Cresson and O . trevoris by MGR, likely synonymous names based on male and female types , and widely collected in western North America. Material from Michigan , Indiana , and Ohio need further study to resolve the taxonomic status of these specimens. Material examined.
