This paper consists of the descriptions of ten new species of loh- 

 neumonidae, several of which are representatives of genera not. 

 previously recognized in the North Anierican fauna. 



Genus NEOTYPUS (Foerster) Holmgren 



No North Arnerican representative of this genus has heretofore 

 been described. The following new species is typical of the genus. 



NEOTYPUS AMERICANUS, new species 



Male. — Length, 7.5 nim. 



Very similar to melanocephalus (Gmelin). As in the male of that 

 species the claws are not pectinate. From the single male of melano- 

 cephalus available to me it differs practically only as follows: eyes 

 shorter than width of vertex, the malar space and oceU-ocular line 

 therefore longer, the former nearly half as long again as the basal 

 width of mandible and the latter about twice as long as the diameter 

 of a lateral ocellus; scutellum practically impunctate, polished, the 

 carinae higher and more strongly converging posteriorly; median 

 areas of propodeum narrower, the areola fully two-thirds as long 

 medially as wide, the petiolar area about twice as long as broad,, 

 closely transversely striate; second tergite nearly twice as wide at 

 apex as at base, gastrocoeli subquadrate, broader than the distance 

 between them. 



White markings of front and face narrower, clypeus only faintly 

 pale at sides; abdominal markings also smaller; hind legs entirely 

 black. 



Type-locality. — Hocking county, Ohio. 



Type.— C&t. No. 27679, U.S.N.M. 



One male received from Prof. C. H. Kennedy of Ohio State Uni- 

 versity. 



NEOTYPUS LAProATOR (Fabricius) 



A female from Oregon (C. F. Baker collection) apparently differs 

 in no way from this European species. 



No. 2595.— Proceedings U. S. National Museum, Vol. 67, Art. 23.
