THE ICHNEUMON-FLIES OF THE SUBFAMILY NEOKHAC- 

 ODINAE, IVITH DESCKIPTIONS OF A NEW GENUS AND 

 THREE NEW SPECIES 



By R. a. Cushman 



The three species of Neorhacodinae described herein bring the 

 Nearctic and Neotropical regions into the known distribution of this 

 anomalous subfamily of Ichneumonidae, add a new genus, and 

 increase to four the number of known species.

Under the name Rhacodes the typical genus was originally de- 

 scribed by Ruschka from a specimen reared as a parasite of the wasp 

 SpiloTnena troglodytes Lind. Ruschka placed the genus in the Bra- 

 conidae and erected for it the new subfamily Rhacodinae. 



Hedicke, finding Rhacodes Ruschka preoccupied by the crustacean 

 genus Rhacodes Koch, renamed it Neorhacodes and changed the sub- 

 family name to Neorhacodinae.
