DESCRIPTIONS OF NEW GENERA AND SPECIES, WITH 

 NOTES ON PARASITIC HYMENOPTERA 



By A. B. Gahan,

In this paper will be found descriptions of three species of Ichneu- 

 monoidea, and two genera and ten species of Chalcidoidea believed 

 to be new to science. Some synonymical and other notes on de- 

 scribed species are also included. 



Superfamily ICHNEUMONOIDEA. 



Family ICHNEUMONIDAE. 



Subfamily OFHIO^rilSr^E. 



Genus CASINARIA Holmgren. 



AmorpJwta orgyiae Howard, type of the genus AmorpTiota, agrees 

 with the characterization of Casinaria given by Szepligeti. Speci- 

 mens of the genotype species of Casinaria are not available for com- 

 parison, but descriptions of that species, Casinaria tenuiventris 

 Gravenhorst, leave no doubt that AmorpTiota is a synonym of Casi- 

 naria. 



CASINARIA INFESTA Cresson. 



Limneria infesta Cresson, Trans. Amer. Ent. Soc, vol. 4, 1872, p. 172. 

 Limnerium sessilis Ashmead, Proc. U. S. Nat. Mus., vol. 12, 1890, p. 433. 

 Limnerium erythrogaster Ashmead, Proc. U. S. Nat. Mus., vol. 13, 1890, p. 434. 

 Limnerium ashmeadi Dalle Torre, Cat. Hym., vol. 3, 1901, p. 90. 

 Anempheres diaphaniae Viereck, Proc. U. S. Nat. Mus., vol. 40, 1912, p. 188. 



After comparison of the types, the writer is convinced that all of 

 the above names represent the same species. 



SAGARITIS DUBITATUS Cresson. 



Mesoleptus dubitatus Cresson, Proc. Ent. Soc. Phila., vol. 3, 1864, p. 259. 

 Limnerium provancheri Dalle Torre, Cat. Hym., vol. 3, 1901, p. 102. 

 Limnerium (Campoletis) prodeniae Viereck, Proc. U. S. Nat. Mus., vol. 40, p. 190. 



Cresson's species undoubtedly belongs in Sagaritis, so that Dalle 

 Torre's name is unnecessary. Viereck's types are in every way 

 typical specimens of dubitatus.
