MISCELLANEOUS DESCRIPTIONS OF NEW PARASITIC HYMENOPTERA WITH SOME SYNONYMICAL NOTES By A. B, Gahan Of the Bureau of Entomology, United States Department of Agriculture. This paper contains descriptions of one new species of Braconidae, tliree new genera and seventeen new species of Chalcidoidea and one new species of Scelionidae. Most of these supposed new forms are from the United States, but one new genus and species from New Zealand, two new genera and species from Java, two new species from Costa Rica, and two new species from Porto Rico, are included. Sj'nonymical notes likewise include notes on species falling in Bra-conidae, Chalcidoidea, and Scelionidae. Superfamily ICHNEUMONOIDEA Family BRACONIDAE OPIUS FULVICOLLIS Thomson Opim fulvicollis Thomson, Opusc. Entom., pt. 20, 1895, p. 2181, no. 9. Optus cupidus Gahant, Proc. Ent. Soc. Wash., vol. 21, 1919, p. 162. Seven specimens of a species agreeing exactly with Thomson's description of 0. fulmcollk were recently received from Dr. Hans Bremer, Stralsund, Pomerania, Germany, parasitic according to the sender upon Pegomyia hyoscyami Panzer. To the surprise of the writer these proved to be identical in every respect with 0. cwpidus Gahan described in 1919 from specimens taken in Manhattan and Brooklyn, New York City, and parasitic upon the same species of Pegomyia. The record is interesting as shov/ing the occurrence of the species in both Europe and America as well as for constituting the first host record for 0. fulvlcollis known to the writer. mOSPILUS CURTICAUDIS, new species This species may be separated at once from all of the other described American species by the short ovipositor which is exserted less than half the length of abdomen.
