This paper consists of the descriptions of one new genus and 

 thirteen new species of North American Ichneumonidae, four new 

 species from the Neotropical Region, short revisions of the North 

 American species of several genera, several generic transfers, and the 

 synonymizing of two European species. 



Genus ISCHNOPSIDEA Viereck 



Ischnus Authors, not Gravenhorst. 



Rheoeidernms (Foerster) Ashmead, Proc. U. S. Nat. Mus., vol. 30, 1906, 

 p. 171, pi. 12, fig. 2. 



Two specimens of a species referable to this genus have recently 

 come to hand. They are specifically distinct from coloradensis Cush- 

 man as well as from the unnamed species referred to in the descrip- 

 tion of coloradensis. 



ISCHNOPSIDEA ALBERTA, new species 



Distinguishable at once from coloradensis Cushman by the larger 

 eyes and consequently shorter malar space, the entirely black an- 

 tennae, and the relatively longer tergites, as well as by many of the 

 following characters : 



Female. — Length 7.5 mm. ; antennae (tips broken but in the para- 

 type about two-thirds as long as body). 



Head large ; temples nearly as broad as eyes, slightly sloping,^ con- 

 vex ; eyes large, parallel within, their long diameter about four times; 

 the length of malar space; face densely, transversely striato-punc- 

 tate, head otherwise, including clypeus, sparsely punctate and pol- 

 ished. Thorax shining, punctate, metapleurum densely so ; scutellum 

 polished, almost impunctate, margined to beyond middle ; propodeum 

 with basal areas punctate, middle areas polished, apical areas trans- 

 No, 2709.— Proceedings U. S. National Museum, Vol. 72, Art! 13.
