Brief Summary
provided by Catalog of Hymenoptera in America North of Mexico
Specimens with black hind femora (sometimes all femora black) are known from Que., Ont., Mich., Wash. Oreg., and Calif. The correct name for this species may be subcarinatus Holmgren. Roman (1925) suppressed longicalcar as a synonym of subcarinatus; he stated that Holmgren's type was lost, but that it appeared certain from the description that Holmgren's "male" of subcarinatus was a longicalcar female. It seems quite likely that Roman was correct, and I was prepared to accept Roman as first revisor. However, Dr. J.-P. Aeschlimann pointed out to me (personal commun., August, 1976) that Holmgren (1873) had in fact been first revisor and had suppressed subcarinatus as a synonym of C. cristator (Gravenhorst). A search is to be made for the subcarinatus type in places to which Holmgren is known to have sent material; if it is not found, and if no specimens of cristator having a black face are found, longicalcar must be suppressed as a synonym of subcarinatus.
