euurae (Ashmead). Western Mont., s.w. Idaho, Utah., s. Ariz., w. Nev., s. Calif. Host: Euura

 (1975) is not euurae.

This is a large genus. As presently defined in the structural sense, it appears to include spe- 

 cies from all zoogeographic regions, but by far the greatest number of species occur in the 

 Holarctic Region. From our knowledge of the habits of a considerable number of the species oc- 

 curring in the Holarctic Region there has developed the supposition that parasitism of sawfly 

 larvae clearly distinquishes Olesicampe from Hyposoter (parasites of Lepidoptera larvae). 

 Structural differentiatiton of the two genera is rather arbitrary, however, particularly when one 

 looks at the world fauna, in which case the differentiation of Olesicampe from Lemophagus also 

 appears arbitrary. Although it seems certain that some of the species currently placed in 

 Olesicampe will prove not to be parasites of sawflies, it appears equally as certain that nearly all 

 of the Nearctic and Palearctic species of Olesicampe are parasites of sawflies. In all cases known 

 to me, Olesicampe species kill the host after it has spun its cocoon and emerge as adults from 

 the host cocoon.
