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.
