264 KANSAS ACADEMY OF SCIENCE, NOTES AND DESCRIPTIONS OF HYMENOPTERA FROM THE WESTERN UNITED STATES, IN THE COLLECTION OF THE UNIVERSITY OF KANSAS. By H. Li Vieeeck, Academy of Natural Sciences, Philadelphia, Pa, THE material furnished me for study by Dr. F. H. Snow, of the University of Kansas, from his collection of undetermined Hy-menoptera, is rich in new species. Parasitic Hymenoptera, particu-larly, are apt to lie idle in collections ; to determine old species and then quite often to describe new species has taken considerable time ; but the results of my work in describing so many new species are not at all surprising, since the field is only partly worked. The species are arranged by states, and systematically, according to Ashmead's classification, but starting with the least specialized and not with the most specialized, as in that classification. Of the super family Ichneumonoidea, four families are represented, in order of' treatment — Evaniidae, Ichneumonidee, Braconidse, and Stephanidse — and the results obtained in each are as follows: Family Evaniid.e. GENUS, OLD SPECIES, NEW SPECIES, Gasteruption 1 (Ariz.) Family Braconid^. GENUS, OLD SPECIES, NEW SPECIES. Rhogas 2 (Ka,) 2 (Ks.) Heterogamus 1 " Lytopylua 1 (Ke.)
